[0042] Embodiment 1:

[0043] Please refer to Figure 1, the stamping production line shown in a preferred embodiment of the present application includes a stamping machine 1, a labeling machine 2, and an inspection and loading machine 3. The labeling machine 2 attaches a label to the surface of the processed product generated by the stamping machine 1 to form a product and transfers the product to the inspection position. The inspection and loading machine 3 sorts the products located at the inspection position into good products and defective products, and transfers the good products to the tray 104.

[0044] In this embodiment, the stamping machine 1 adopts an existing automatic stamping machine 1, which has a loading end 11, a punch 12, and an unloading end 13. The raw material enters the automatic stamping machine 1 from the loading end 11, forms a processed product after being stamped by the punch 12, and leaves the automatic stamping machine 1 from the unloading end 13. Since the specific structure of the automatic stamping machine 1 belongs to the prior art, it will not be described in detail here.

[0045] Please refer to Figure 2 , in this embodiment, the processed product is inscribed in a rectangle, has opposite first surface 101 and second surface 102. The first surface 101 of the processed product is a plane, and the second surface 102 is provided with protruding cylindrical positioning holes 103 at the four corners of the processed product. In this embodiment, when the processed product leaves the unloading end 13 of the stamping machine 1, its first surface 101 is located below the second surface 102.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, the labeling machine 2 adopts the CCD vision automatic alignment and bonding technology, and includes a workbench 22, a housing 21, a workpiece conveyor belt 23, two groups of limiting tracks 24, a label belt translation mechanism (not shown), a workpiece camera (not shown), a label camera (not shown), a transfer manipulator (not shown), and a labeling display component 25. The workpiece conveyor belt 23 is horizontally arranged on the workbench 22, and has a first end 231 close to the punching machine 1 and a second end 232 far from the punching machine 1. The height of the first end 231 of the workpiece conveyor belt 23 is lower than the height of the discharging end 13 of the punching machine 1, and the first end 231 of the workpiece conveyor belt 23 is connected to the discharging end 13 of the punching machine 1 through a slideway 14. The two groups of limiting tracks 24 are both arranged on the workbench 22 and have the same structure, and their positions respectively correspond to the first end 231 and the second end 232 of the workpiece conveyor belt 23, and are used to correct the setting direction of the workpiece. Each group of limiting tracks 24 includes a converging member 241 and a parallel member 242. The parallel member 242 includes two linear structures parallel to the workpiece conveyor belt 23 and with a spacing equal to the width of the workpiece. The converging member 241 includes two vertically arranged and opposite inclined surfaces 2411, which are connected to the side of the parallel member 242 close to the punching machine 1. The spacing between the inclined surfaces 2411 of the converging member 241 on the side close to the punching machine 1 is greater than the width of the workpiece, and the spacing between the inclined surfaces 2411 of the converging member 241 on the side far from the punching machine 1 is equal to the width of the workpiece. The limiting tracks 24 are horizontally arranged and the distance between the bottom and the workpiece conveyor belt 23 is less than the height of the workpiece. When the workpiece passes through the inside of the limiting tracks 24 along with the workpiece conveyor belt 23, the sides of the converging member 241 and the parallel member 242 are in contact with the sides of the workpiece, so that the setting direction of the workpiece is adjusted and corrected to be parallel to the direction of the conveyor belt. The limiting tracks 24 can adapt to workpieces of different sizes by adjusting the distance between the two linear tracks 6342. Both the workpiece camera and the label camera adopt CCD cameras and are both arranged on the workbench 22. The detection position of the workpiece camera is located between the two groups of limiting tracks 24. A plurality of labels are attached to the label belt in a flush manner. The label belt is installed on the label belt translation mechanism, so that the label belt moves synchronously and in the same direction as the workpiece conveyor belt 23. The label camera is arranged flush with the workpiece camera, and the detection position of the label camera is located on the label belt. The label belt moves along with the label belt translation mechanism, so that each label on it is respectively located at the detection position of the label camera. The transfer manipulator is arranged between the workpiece camera and the label camera. The workpiece reaches the first end 231 of the workpiece conveyor belt 23 from the slideway 14, so that the first surface 101 of the workpiece is in contact with the workpiece conveyor belt 23.The processed product moves along with the processed product conveyor belt 23 under the action of friction force. After the direction is corrected by the limit track 24, it reaches the detection position of the processed product camera along with the processed product conveyor belt 23. At this time, a label on the label tape is located at the detection position of the label camera. The transfer manipulator removes this label and transfers it to the second surface 102 of the processed product. Since the pressure-sensitive adhesive is attached to the label, the label is attached to the processed product to form a product. The product reaches another limit track 24 along with the processed product conveyor belt 23 to correct the set direction again, and then leaves the conveyor belt to reach the detection position. The images detected by the processed product camera and the label camera can be viewed through the labeling display component 25. The labeling display component 25 includes a display 251, a keyboard 252, and a mouse 253. The housing 21 is arranged above the workbench 22 to protect the internal structure of the labeling machine 2. The bottom of the workbench 22 is provided with universal wheels 221 for moving the labeling machine 2.

[0047] Please refer to Figure 1 and Figure 4 , the detection and loading machine 3 includes another workbench 22, another housing 21, a vision detection mechanism 4, a loading mechanism 5, a storage mechanism 6, and an integrated display component 7. The vision detection mechanism 4, the loading mechanism 5, and the storage mechanism 6 are all arranged above the workbench 22. The housing 21 is used to protect the internal structures of the vision detection mechanism 4, the loading mechanism 5, and the storage mechanism 6. The vision detection mechanism 4 conveys the product located at the detection position to the transfer position and performs detection. The loading mechanism 5 transfers the qualified product located at the transfer position into the accommodation groove 105 of the tray 104. At this time, the tray 104 is located at the preset position. The tray 104 includes a plurality of accommodation grooves 105 arranged in an array. The storage mechanism 6 includes a first bin 61 for storing a number of stacked trays 104, a second bin 62 for storing a number of stacked trays 104 with a plurality of qualified products placed therein, and a shifting component 63. The shifting component 63 transfers the bottommost tray 104 in the first bin 61 to the preset position, and transfers the tray 104 to the bottom layer of the second bin 62 after the tray 104 is filled with products. The shifting component 63 has a plurality of preset positions. When the tray 104 is located at different preset positions, a plurality of accommodation grooves 105 correspond to the loading mechanism 5. The working states and set parameters of the vision detection mechanism 4, the loading mechanism 5, and the storage mechanism 6 are all displayed and input through the integrated display component 7.

[0048] Please refer to Figure 1 , Figure 4 and Figure 5, the vision inspection mechanism 4 includes a flipping component 41, an inspection conveyor belt 42, another limiting track 24, an inspection camera 43, a limiting component 44, and a defective product box 45. The inspection conveyor belt 42 is horizontally arranged on the workbench 22 and has opposite receiving ends 421 and transfer ends 422. The flipping component 41 is rotatably connected to the receiving end 421 of the inspection conveyor belt 42 and includes a flipping platform 411, another converging member 241, and a driving member 412. The flipping platform 411 is a planar structure, on which a converging member 241 is arranged and is quickly flipped under the drive of the driving member 412. When the flipping platform 411 forms a 180-degree angle with the inspection conveyor belt 42, the position inside the converging member 241 is the inspection position. The flipping platform 411 drives the product thereon to flip towards the inspection conveyor belt 42, so that the second surface 102 of the processed product is located below the first surface 101 and contacts the inspection conveyor belt 42. The inspection camera 43 uses a CCD camera and is supported on the workbench 22. The inspection position of the inspection camera 43 is located in the middle of the parallel member 242 of the limiting track 24 and is used to detect the morphological structure of the second surface 102 of the processed product. The limiting component 44 is arranged on the workbench 22 and includes a limiting member 441 and a releasing member 442. The releasing member 442 uses a cylinder and is connected to the limiting member 441. When the releasing member 442 is in a stretched state, the limiting member 441 is located at one end of the parallel member 242 of the limiting track 24 away from the converging member 241, and the distance between the bottom of the limiting member 441 and the inspection conveyor belt 42 is less than the height of the processed product. When the releasing member 442 contracts, it drives the limiting member 441 to move vertically upward, so that the distance between the bottom of the limiting member 441 and the inspection conveyor belt 42 is greater than the height of the processed product. The defective product box 45 is arranged on the workbench 22, is arranged adjacent to the transfer end 422 of the inspection conveyor belt 42, and is located below the extension line of the inspection conveyor belt 42. When the product reaches the inspection conveyor belt 42, it moves along the inspection conveyor belt 42 into the inside of the limiting track 24. When passing through the inspection position of the inspection camera 43, the inspection camera 43 inspects the product. When the inspection result of the product is a qualified product, the releasing member 442 is in a stretched state, and the qualified product is limited between the parallel member 242 and the limiting member 441. At this time, the position where the product is located is the transfer position. When the inspection result of the product is a defective product, the releasing member 442 contracts, and the defective product falls from the transfer end 422 of the inspection conveyor belt 42 and enters the defective product box 45.

[0049] By setting the flipping component 41, the inspection position of the inspection camera 43 is the second surface 102 of the processed product, preventing the label attached to the first surface 101 of the processed product from interfering with the inspection of the product. By setting the limiting member 441 and the defective product box 45, the sorting of qualified products and defective products is achieved with higher efficiency.

[0050] Please refer to Figure 1, the tray loading mechanism 5 includes a first transplanting mechanism 51 and a second transplanting mechanism 52. The first transplanting mechanism 51 transfers the product at the transfer position to the transfer position, and the second transplanting mechanism 52 transfers the product at the transfer position to the tray 104 at the preset position. The tray loading mechanism 5 is electrically connected to the vision inspection mechanism 4 and only transfers the product when the inspection result is a good product.

[0051] Please refer to Figure 1 , Figure 4 and Figure 6 , the first transplanting mechanism 51 includes a cam transplanting manipulator 511, a positioning component 512, a rotating component 513, a first sampling component 514, a second sampling component 515 and a third sampling component 516. The cam transplanting manipulator 511, the positioning component 512 and the rotating component 513 are all arranged on the workbench 22.

[0052] In this embodiment, the cam transplanting manipulator 511 adopts an Ouda PA-180 manipulator, which has a moving block 5111 that moves between a first position and a second position. The moving block 5111 is connected to a horizontally arranged connecting rod 5112. The first sampling component 514 and the third sampling component 516 are respectively connected to two ends of the connecting rod 5112, and the second sampling component 515 is connected to the midpoint of the connecting rod 5112. The distance between the first sampling component 514 and the second sampling component 515 is equal to the horizontal distance between the first position and the second position. In this embodiment, the first sampling component 514, the second sampling component 515 and the third sampling component 516 have the same structure, and each includes two vacuum suction nozzles 5141. The distance between the vacuum suction nozzle 5141 and the connecting rod 5112 and the distance between the two vacuum suction nozzles 5141 can be adjusted according to the product structure. When the moving block 5111 is at the first position, the vacuum suction nozzle 5141 is opened. The position of the first sampling component 514 is directly above the transfer position to suck the product at the transfer position. The position of the second sampling component 515 is directly above the positioning component 512, and the position of the third sampling component 516 is directly above the rotating component 513. When the moving block 5111 is at the second position, the vacuum suction nozzle 5141 is closed, and the products respectively fall to the positioning component 512, the rotating component 513 and the transfer position.

[0053] The positioning component 512 includes a support frame 5121 and a positioning plate 5122. The support frame 5121 is arranged on the workbench 22, and the positioning plate 5122 is detachably connected to the support frame 5121 and is horizontally arranged. A set of circular limiting holes 5123 are arranged on the upper surface of the positioning plate 5122. The depth of the limiting holes 5123 is equal to the height of the positioning holes 103 of the workpiece. The inner diameter of the limiting holes 5123 gradually decreases from the surface to the inside of the positioning plate 5122 until it is equal to the outer diameter of the positioning holes 103 of the workpiece. A total of four limiting holes 5123 are arranged and their positions are matched with the positioning holes 103 of the workpiece. When the first sampling component 514 places the product on the positioning plate 5122, the second surface 102 of the workpiece is located below the first surface 101, and the four positioning holes 103 of the workpiece are completely embedded in the limiting holes 5123 of the positioning plate 5122 under the action of gravity, realizing the precise positioning of the product.

[0054] The rotating component 513 includes a bearing platform 5131 and a first rotating cylinder 5132. The structure of the bearing platform 5131 is the same as that of the positioning plate 5122, and it is detachably connected to the first rotating cylinder 5132 and rotates driven by the first rotating cylinder 5132 to realize the direction change of the product. The upper surface of the bearing platform 5131, the upper surface of the positioning plate 5122 and the transfer position are at the same height. In this embodiment, after the second sampling component 515 transfers the product located on the positioning plate 5122 to the bearing platform 5131, the first rotating cylinder 5132 drives the product to rotate 180 degrees. After the third sampling component 516 sucks the product on the bearing platform 5131, the first rotating cylinder 5132 returns to its original position. In other embodiments, the rotation angle of the first rotating cylinder 5132 can be different from that in this embodiment. For example, it can also not rotate, rotate 90 degrees clockwise or rotate 90 degrees counterclockwise. It can be selected and set according to the actual situation.

[0055] Please refer to Figure 1 、 Figure 4 and Figure 7, the second transplanting mechanism 52 includes a buffer component 521, a Cartesian robot 522, and a fourth sampling component 523 disposed on the workbench 22. The buffer component 521 includes a turntable 5211 provided with four buffer areas and a second rotary cylinder 5212 for driving the turntable 5211 to rotate. The turntable 5211 is detachably connected to the second rotary cylinder 5212. The structure of the buffer area is matched with the second surface 102 of the processed product for storing the product. The turntable 5211 is horizontally arranged and its upper surface is at the same height as the transfer position. The turntable 5211 is circular and rotates around its center, and the rotation angle of the second rotary cylinder 5212 is 90 degrees clockwise. The four buffer areas (not shown) are evenly arranged around the center of the turntable 5211, so that there is a buffer area at the transfer position before and after the turntable 5211 rotates. Each buffer area includes a set of limiting holes 5123 that fit the product for placing the product. In this embodiment, the Cartesian robot 522 has degrees of freedom in both the horizontal and vertical directions. The fourth sampling component 523 is connected to the Cartesian robot 522 and has a starting position and multiple ending positions. The starting position of the fourth sampling component 523 is centrosymmetric with the transfer position along the center of the turntable 5211. And the starting position of the fourth sampling component corresponds to a buffer area. The tray 104 includes a plurality of accommodating grooves 105 arranged in an array. When the tray 104 is in the preset position, each ending position of the fourth sampling component 523 corresponds to an accommodating groove 105. The third sampling component 516 places the product in the buffer area at the transfer position. The product reaches directly below the starting position of the fourth sampling component 523 after two rotations with the turntable 5211. The fourth sampling component 523 sucks the product and transfers it into the target accommodating groove 105.

[0056] The storage mechanism 6 includes a first bin 61, a second bin 62, and a shifting component 63. Multiple trays 104 are stacked and stored in the first bin 61. A release component 613 is provided at the bottom of the first bin 61 for releasing the tray 104 at the bottom layer position therein to the shifting component 63. The shifting component 63 transfers the tray 104 to the preset position. The shifting component 63 has multiple preset positions. When the tray 104 is at each preset position, a row of accommodating grooves 105 are respectively directly below the respective ending positions of the fourth sampling component 523. The Cartesian robot 522, the fourth sampling component 523, and the shifting component 63 cooperate with each other to sequentially place a plurality of products into the respective accommodating grooves 105 of the tray 104. The shifting component 63 transfers the tray 104 with the products placed therein to the bottom of the second bin 62 to complete the automatic storage of the products.

[0057] The first bin 61 and the second bin 62 both include two carrier frames 611 arranged in parallel with horizontal tops. Above each carrier frame 611, two vertically arranged angle steels 612 are fixedly connected, and the four angle steels 612 enclose a rectangular space that fits the tray 104. The tray 104 has a tray body (not shown) and side edges 106. The tray body is configured as a rectangular box structure with an open top, and a plurality of receiving grooves 105 are arranged in an array therein. The side edges 106 are annular, horizontally arranged and connected to the outside of the tray body for picking up and placing the tray 104. When a plurality of trays 104 are stacked, there is a gap between the bottom of the side edge 106 of the upper tray 104 and the top of the side edge 106 of the lower tray 104. On the tops of the two carrier frames 611 of the second bin 62, two one-way buckles 621 are provided. The one-way buckle 621 is configured as a right triangle, with the upper surface being horizontal and the lower surface being inclined towards the upper inner side of the second bin 62. The one-way buckle 621 is rotatably connected to the carrier frame 611 through a compression spring. When it receives an upward force, the one-way buckle 621 opens upward. When it receives a downward force, the one-way buckle 621 does not rotate. The stacked trays 104 are supported on the plane above the one-way buckle 621. When the tray 104 is forced to move upward from below the second bin 62, the tray 104 can pass through the one-way buckle 621 and enter the bottom of the second bin 62.

[0058] The displacement assembly 63 includes a first tray connecting member 631, a second tray connecting member 632, a support assembly 633 and a drive assembly 634. The drive assembly 634 includes a linear motor 6341, a linear track 6342, a sliding plate 6343 and two tray cylinders 6344. The linear track 6342 extends from below the first bin 61 to below the second bin 62 and is parallel to each carrier frame 611. The moving block slides along the linear track 6342 under the drive of the linear motor 6341. Above the sliding plate 6343, two tray cylinders 6344 with the same structure and synchronous lifting are vertically arranged. The tops of the two single-stroke cylinders respectively support the first tray connecting member 631 and the second tray connecting member 632. The first tray connecting member 631 and the second tray connecting member 632 have the same structure and are used to support the middle position of the bottom surface of the tray 104 and drive the tray 104 to move. When the first tray connecting member 631 is directly below the first bin 61, the second tray connecting member 632 is at a preset position closest to the second bin 62. When the first tray connecting member 631 is at the preset position closest to the second bin 62, the second tray connecting member 632 is directly below the second bin 62. The support assembly 633 includes two support cylinders 6331. The two support cylinders 6331 are respectively arranged on both sides of the preset position closest to the second bin 62, and a support plate 6332 parallel to the linear track 6342 is fixedly connected thereto, for supporting the bottom of the side edge 106 of the tray 104 at the preset position closest to the second bin 62.

[0059] When the first receiving member 631 is directly below the first bin 61 and the tray cylinder 6344 is in a compressed state, the release assembly 613 places the bottom tray 104 in the first bin 61 above the first receiving member 631. The linear motor 6341 drives the sliding plate 6343 to move, so that the first receiving member 631 reaches the preset position closest to the first bin 61, and starts to place the product into the tray 104 above the first receiving member 631. After the placement is completed, the first receiving member 631 reaches the preset position closest to the second bin 62. At this time, the second receiving member 632 is directly below the second bin 62. After the two tray cylinders 6344 are stretched synchronously, the support cylinder 6331 is stretched, and the two tray cylinders 6344 are reset synchronously. At this time, the tray 104 is supported above the support plate 6332. The linear motor 6341 drives the sliding plate 6343 to move, so that the first receiving member 631 returns directly below the first bin 61. At this time, the second receiving member 632 is directly below the tray 104. The support cylinder 6331 is reset, so that the tray 104 is supported above the second receiving member 632. The release assembly 613 places another tray 104 above the first receiving member 631. By repeating the foregoing steps, when the two tray cylinders 6344 are stretched synchronously, the second receiving member 632 drives the tray 104 to move upward from below the second bin 62, so that the tray 104 enters the second bin 62 from the bottom of the second bin 62 through the one-way buckle 621.

[0060] The release assembly 613 includes a lifting cylinder 614, a telescopic cylinder 615, and a tray (not shown). The first bin 61 includes two groups of release assemblies 613 that are supported above the carrier 611 and are arranged oppositely. The lifting cylinder 614 is fixedly connected to the angle steel 612, the telescopic cylinder 615 is connected to the lifting cylinder 614, and the tray is connected to the telescopic cylinder 615. The lifting cylinder 614 is a double-stroke cylinder. When the lifting cylinder 614 is in a compressed state and the telescopic cylinder 615 is in an extended state, the tray extends into the first bin 61, and the side 106 of the bottom tray 104 in the first bin 61 is supported above the tray. When the lifting cylinder 614 is stretched to the first stroke, the bottom tray 104 and the multiple trays 104 above it descend, so that the bottom tray 104 is supported above the first receiving member 631 that is directly below the first bin 61. The telescopic cylinder 615 switches to a retracted state, the tray moves away from the side 106 of the bottom tray 104, and the lifting cylinder 614 contracts to the second stroke. At this time, the position of the tray corresponds to the gap between the side 106 of the bottom tray 104 and the side 106 of the tray 104 above it. The telescopic cylinder 615 switches to an extended state, and the tray is inserted into the above gap. The lifting cylinder 614 contracts, driving the tray to support the multiple trays 104 back to the initial position. At this time, only one tray 104 is supported above the first receiving member 631, realizing the release of a single tray 104.

[0061] The first storage bin 61 and the second storage bin 62 are also respectively provided with an infrared sensor 616 for sensing the number of stacked trays 104 in the first storage bin 61 and the second storage bin 62, and giving a reminder when the number of trays 104 in the first storage bin 61 is less than a preset value or the number of trays 104 in the second storage bin 62 is less than a preset value.

[0062] The integrated display component 7 is arranged on the workbench 22 and includes a screen 71, a keyboard box 72, a fault alarm 73, an emergency stop knob 74 and a plurality of indicator lights 75. The screen 71 displays in real time the images captured by the detection camera 43 and the detection results. The operation conditions of the vision detection mechanism 4, the tray loading mechanism 5 and the storage mechanism 6 are controlled and adjusted through another keyboard 252 and another mouse 253 accommodated in the keyboard box 72. Each indicator light 75 is respectively used to indicate the working states of the vision detection mechanism 4 and the tray loading mechanism 5, and to prompt adding empty trays 104 into the first storage bin 61 and taking out full trays 104 from the second storage bin 62.

[0063] A plurality of universal wheels 221 and leveling screws 81 are arranged at the bottom of the workbench 22 of the detection tray loading machine 3. The leveling screws 81 can extend or contract by rotating, which is convenient for the movement, positioning and leveling of the labeling machine 2 and the detection tray loading machine 3.

[0064] When the stamping production line in the present invention is used for production, the stamping machine 1 automatically stamps raw materials to generate processed products, and the processed products reach the labeling machine 2 through the slideway 14 with their second surfaces 102 facing downwards. The labeling machine 2 attaches a label to the first surface 101 of the processed product to generate a product, and transfers the product to the detection position. The vision detection mechanism 4 flips the product located at the detection position and detects the second surface 102 of the processed product. The products with defective detection results slide into the defective product box 45 after reaching the transfer position, and the products with good detection results are transferred to the tray 104 located at the preset position by the tray loading mechanism 5 after reaching the transfer position. The storage mechanism 6 transfers the tray 104 from the first storage bin 61 to the preset position, and transfers the tray 104 filled with products to the second storage bin 62 for storage.

[0065] Through the production of products by the stamping production line in the present invention, seamless connection is achieved between each process, and the production efficiency is relatively high. The whole process realizes automation, reduces the intensity of manual labor and the total amount of manual operations, and reduces the labor cost on the one hand. By setting the vision detection mechanism 4, the detection and sorting of products are realized, and the overall qualified product rate is improved. The distance between the limit tracks 24 is adjustable, and the positioning plate 5122, the bearing table 5131 and the turntable 5211 are all arranged in a movably connected manner, so that the stamping production line in the present invention can be adapted to various products with different specifications and has relatively high universality.

[0066] Embodiment 2:

[0067] The difference between this embodiment and the first embodiment is only that it does not include the release member 442. When the product is detected as a defective product, the first sampling assembly 514 sucks up the product and automatically closes directly above the defective product box 45, causing the product to fall into the defective product box 45.

[0068] Embodiment Three:

[0069] The difference between this embodiment and the first embodiment is only that it does not include the positioning assembly 512 and the second sampling assembly 515. The distances from the rotating assembly 513 to the transfer position and the transfer intermediate position are equal. When the first sampling assembly 514 is directly above the transfer position, the third sampling assembly 516 is directly above the rotating assembly 513.

[0070] Embodiment Four:

[0071] The difference between this embodiment and the first embodiment is only that it does not include the rotating assembly 513 and the third sampling assembly 516. The distances from the positioning assembly 512 to the transfer position and the transfer intermediate position are equal. When the first sampling assembly 514 is directly above the transfer position, the second sampling assembly 515 is directly above the positioning assembly 512.

[0072] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
