DETAILED DESCRIPTION

[0020] The following are specific embodiments of the invention and combined with the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] Embodiment 1

[0022] like Figure 1 As shown, the metal stamping parts processing production line includes a conveying device 1, a multi-station coding device 2, a multi-station detection device 3, a multi-position material storage device 4, a material replenishment device 5, a transfer device 6 and a one-time insertion multi-material transfer device 7.

[0023] Specifically, Figure 1 As shown, the conveying device 1 includes a first conveyor belt 10 distributed along a first direction X, and a second conveyor belt 11 connected to the output side of the first conveyor belt 10 and distributed along a second direction Y. The first direction X and the second direction Y are distributed vertically.

[0024] For example, the first conveyor belt 10 is inclined, the second conveyor belt 11 is horizontally distributed, and the feed side of the second conveyor belt 11 is located below the lower end of the first conveyor belt 10. The stamping parts conveyed from the first conveyor belt 10 fall onto the second conveyor belt 11.

[0025] The first conveyor belt 10 and the second conveyor belt 11 are both crawler conveyor belts. Of course, the conveying device 1 may also only include the first conveyor belt 10.

[0026] The stamping equipment stamps the metal sheet to obtain a metal stamping part, and the stamping part is transferred to the upper conveying surface of the first conveyor belt 10 .

[0027] An industrial detection camera is provided on the feeding side of the second conveyor belt 11 to detect whether there is incoming material.

[0028] The multi-station coding device 2, the multi-station detection device 3 and the multi-station storage device 4 are arranged in sequence according to the production direction, that is, the stamping parts on two adjacent devices are transferred and released by different manipulators.

[0029] Specifically, Figure 2 and Figure 3 As shown, the multi-station coding device 2 is used to code the stamping parts conveyed by the conveying device 1; for example, the multi-station coding device 2 includes a first device platform 20, on which are provided a plurality of groups of coding positioning fixtures 21 distributed in parallel, and each group of coding positioning fixtures 21 respectively has a plurality of stamping part fixing stations, and each group of coding positioning fixtures 21 respectively has four stamping part fixing stations, and the coding positioning fixture 21 is connected to a first linear drive component 22, which is, for example, a linear motor group, and on the first device platform 20, a coding component 23 is provided which moves in a direction perpendicular to the driving direction of the first linear drive component 22, that is, the moving direction of the coding component 23 and the driving direction of the first linear drive component 22 are vertically distributed.

[0030] The first linear drive component 22 drives the coding positioning fixture 21 to reach the coding position, and the coding component 23 completes the coding of the stamping parts on the coding positioning fixture 21. The first linear drive component 22 drives the coding positioning fixture 21 to move a stamping part fixed station. At this time, the coding component 23 moves along the second direction Y to complete the coding of several stamping parts. Repeat the above actions to complete the coding of several stamping parts on the same coding positioning fixture 21.

[0031] The coding component 23 is, for example, a laser component.

[0032] The coding assembly 23 includes a coding gantry, on which is disposed at least one laser coding device that can move in the second direction Y. The movement of the laser coding device can also be a linear motor group.

[0033] Secondly, the multi-station coding device 2 is provided with a first manipulator 8 for obtaining the stamping parts conveyed by the conveying device 1 and releasing them on the coding positioning fixture 21. The first manipulator 8 is a spider manipulator. The coding positioning fixture 21 actively moves below the first manipulator 8, and the first manipulator 8 obtains the stamping parts on the conveying device 1 and releases the stamping parts on the coding positioning fixture 21, such as the first manipulator 8 obtains the stamping parts from the first conveyor belt 10, or obtains the stamping parts from the second conveyor belt 11. And the multi-station coding device 2 is provided with a second manipulator 9 for obtaining the stamping parts after coding and releasing them on the multi-station detection device 3. The second manipulator 9 is a multi-axis mobile manipulator, for example, it moves in the third direction Z, the first direction X and the second direction Y. Of course, it can also move in both the third direction Z and the second direction Y.

[0034] Preselected, the second manipulator 9 of the present embodiment includes a gantry frame, at least part of which extends outside the first device platform 20. At this time, the second suction cup manipulator on the gantry frame can be moved from the first device platform 20 to above the multi-station detection device 3 outside the first device platform 20.

[0035] like Figure 4 As shown, the multi-station detection device 3 is a flatness detection device, which includes a second device platform 30, on which are arranged a plurality of detection positioning fixtures 31 distributed in parallel, and each detection positioning fixture 31 has a plurality of stamping part fixing positions, each detection positioning fixture 31 is connected to a second linear drive component 32, and a detection component 33 corresponding to each detection positioning fixture 31 is also arranged on the second device platform 30. The second linear drive component 32 also uses a linear motor group, and the detection component 33 is such as an industrial camera, etc.

[0036] Preselectively, the multi-station coding device 2 has more stations than the multi-station detection device 3. For example, the multi-station coding device 2 has four columns of stations distributed along the first direction X, and the multi-station detection device 3 has three columns of stations distributed along the first direction X. At this time, at least one of the coding positioning jigs 21 of the multi-station coding device 2 can be used to perform material receiving, at least two coding positioning jigs 21 can perform coding at the coding station, and the remaining one coding positioning jig 21 can be used to complete the material removal after coding, so that the entire process does not require a waiting period for the previous and next actions, so as to improve production efficiency.

[0037] As the detection and positioning fixture 31 moves in the first direction X, the detection assembly 33 can now complete the detection of the stamping part, such as flatness detection.

[0038] When the inspection is completed, there are two situations for the stamping parts at this time, the first is qualified stamping parts, and the second is unqualified stamping parts. The qualified stamping parts are obtained by the second manipulator 9 as above and released to the transfer device 6, and the unqualified stamping parts are transferred and released to the unqualified material output device 34. In order to make the total number of each loading of the transfer device 6 equal to the set total number, the present embodiment further provides a feeding device 5, and the feeding device 5 and the transfer device 6 of the present embodiment are staggered and arranged on the multi-station detection device 3. The transfer device 6, the feeding device 5 and the detection and positioning fixture 31 of the present embodiment are spaced apart in the second direction Y. Secondly, the unqualified material output device 34 is located next to the feeding device 5, and the unqualified material output device 34 is used to convey the stamping parts that fail the inspection.

[0039] Furthermore, if Figure 4 As shown, the feeding device 5 includes a feeding fixture 50 with a plurality of fixed positions for stamping parts, and a fourth manipulator 51 for obtaining the stamping parts on the feeding fixture 50 and releasing them on the transfer device 6. The feeding fixture 50 is connected to the third linear drive component 52. The third linear drive component 52 is, for example, a linear motor group, and the fourth manipulator 51 is, for example, an industrial robot with a suction cup. The feeding fixture 50 actively moves in the material taking area of ​​the fourth manipulator 51 under the drive of the third linear drive component 52. At this time, the multi-axis can move the fourth manipulator 51 to obtain the qualified stamping parts pre-placed on the feeding fixture 50 from the feeding fixture 50 and release them on the transfer device 6. At this time, the total number of qualified stamping parts on the transfer device 6 is equal to the set total number of stamping parts, so that the number of stamping parts obtained by the multi-material transfer device 7 at one time is equal to the total number of material levels of the multi-material storage device 7 at one time. For example, the multi-level storage device 7 has several rows and each row has four stamping parts. The multi-material transfer device 7 is inserted once to obtain four qualified stamping parts from the transfer device 6 at a time, which can prevent the stamping parts positions of the multi-level storage device 7 from being empty, or prevent the missing stamping parts from being manually inserted later.

[0040] That is, the feeding device 5 is used to replenish the unqualified stamping parts after the multi-station inspection device 3 is inspected once and make the stamping parts on the transfer device 6 reach the set qualified number. Figure 8 As shown, the transfer device 6 includes a plurality of jigs 60 for transferring stamping parts.

[0041] Specifically, Figure 5-Figure 7 As shown, the multi-level storage device 4 of this embodiment is a basket-inserting multi-level storage device, including a device frame 40, on which are provided an empty basket loading mechanism 41, an empty basket orientation mechanism 42 and a loading basket descending mechanism 43, and the device frame 40 is also provided with a fifth manipulator 44 for taking the empty basket conveyed upward by the empty basket loading mechanism 41 and releasing it to the empty basket orientation mechanism 42, and taking the loaded basket on the empty basket orientation mechanism 42 and releasing it to the loading basket descending mechanism 43. And the fifth manipulator 44 of this embodiment has two and the multi-material transfer device 7 is a multi-axis manipulator, such as a multi-axis (six-axis) industrial robot, which carries four suction cups.

The two translation clamping portions 445 move toward each other and combine with the adapter frame / plate 444 to clamp the basket.

[0044] Secondly, the empty basket feeding mechanism 41 of the present embodiment includes an empty basket conveyor belt 410, one side of the empty basket conveyor belt 410 is an empty basket entry end, and an empty basket lifting and hoisting assembly 411 is provided at the other end of the empty basket conveyor belt 410 away from the empty basket entry end. The empty basket lifting and hoisting assembly 411 adopts a supporting frame or a grabbing manipulator to obtain the empty basket and move upward in the third direction Z. When the empty basket is lifted to a set height, one of the fifth manipulators 44 is used to take the empty basket conveyed upward by the empty basket feeding mechanism 41. The empty basket is obtained and released to the orienting mechanism 42 for empty basket. After the orienting mechanism 42 for empty basket orients and rotates the empty basket to the set angle, the multi-material transfer device 7 obtains and inserts equal amounts of stamping parts on the transfer device 6 into the four parallel or parallel stamping parts positions of the empty basket. Then the multi-material transfer device 7 repeats the action of obtaining and releasing the insertion until the entire empty basket is full. When the empty basket is full, another fifth manipulator 44 is used to obtain the loaded basket on the orienting mechanism 42 for empty basket and release it to the loading basket descending mechanism 43.

[0045] In order to ensure orderly processing and traceability, each empty basket has a QR code, and the multi-level storage device 4 also includes a scanner 45. When the empty basket loading mechanism 41 forces the empty basket to rise to a set height or rotate to a set angle, the scanner 45 scans the QR code to obtain basket information, whether there is a basket, etc., so that the processing can be continuous.

[0046] The loading basket descending mechanism 43 includes a loading basket lifting assembly 430 , that is, the fifth manipulator 44 releases the fully loaded loading basket onto the loading basket lifting assembly 430 , and at this time the loading basket lifting assembly 430 descends and is output from the loading basket output belt 431 .
