Detailed implementation manners

[0038] The following are specific embodiments of the invention and, in combination with the accompanying drawings, further describe the technical solutions of the invention, but the invention is not limited to these embodiments.

[0039] Embodiment 1

[0040] As Figure 1 shown, the processing production line of this metal stamping part includes a conveying device 1, a multi-station coding device 2, a multi-station detection device 3, a multi-level storage device 4, a feeding device 5, a transfer device 6, and a one-time multi-material insertion transfer device 7.

[0041] Specifically, as Figure 1 shown, the conveying device 1 includes a first conveyor belt 10 distributed along the first direction X, and a second conveyor belt 11 connected to the output side of the first conveyor belt 10 and distributed along the second direction Y. The first direction X and the second direction Y are perpendicularly distributed.

[0042] As the first conveyor belt 10 is inclined, the second conveyor belt 11 is horizontal, and the feeding 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.

[0043] Both the first conveyor belt 10 and the second conveyor belt 11 are caterpillar conveyor belts. Of course, the conveying device 1 may also only include the first conveyor belt 10.

[0044] The stamping equipment stamps metal sheets to obtain stamped metal parts, and the stamped parts are transferred to the upper conveying surface of the first conveyor belt 10.

[0045] An industrial inspection camera is provided on the feeding side of the second conveyor belt 11 to detect whether there is incoming material.

[0046] The multi-station coding device 2, the multi-station detection device 3, and the multi-level storage device 4 are arranged in sequence according to the production direction, that is, the stamped parts on adjacent two devices are transferred and released by different manipulators.

[0047] Specifically, as Figure 2 and Figure 3 shown, the multi-station coding device 2 is used to code the stamped parts conveyed by the conveying device 1; for example, the multi-station coding device 2 includes a first device platform 20, on which several groups of juxtaposed coding positioning jigs 21 are provided, and each group of coding positioning jigs 21 respectively has several stamped part fixing stations. Each group of coding positioning jigs 21 respectively has four stamped part fixing stations. The coding positioning jigs 21 are connected to the first linear driving component 22. The first linear driving component 22 is, for example, a linear motor group. A coding component 23 that moves in a direction perpendicular to the driving direction of the first linear driving component 22 is provided on the first device platform 20, that is, the moving direction of the coding component 23 and the driving direction of the first linear driving component 22 are perpendicularly distributed.

[0048] The first linear driving component 22 drives the coding positioning jigs 21 to reach the coding position, and the coding component 23 then completes the coding of the stamped parts on the coding positioning jigs 21. The first linear driving component 22 drives the coding positioning jigs 21 to move one stamped part fixing station. At this time, the coding component 23 completes the coding of several stamped parts by moving along the second direction Y. Repeating the above actions completes the coding of several stamped parts on the same coding positioning jig 21.

[0049] The coding component 23 is, for example, a laser and other components.

[0050] The coding component 23 includes a coding gantry, and at least one laser coder that can move in the second direction Y is provided on the coding gantry. The movement of the laser coder can also be a linear motor group.

[0051] Secondly, a first robot arm 8 for picking up and releasing the stamped parts conveyed by the conveying device 1 onto the coding positioning fixture 21 is provided on the multi-station coding device 2. The first robot arm 8 is a spider robot arm. The coding positioning fixture 21 moves actively below the first robot arm 8, and the first robot arm 8 picks up the stamped parts on the conveying device 1 and releases the stamped parts onto the coding positioning fixture 21. For example, the first robot arm 8 picks up the stamped parts from the first conveyor belt 10 or from the second conveyor belt 11. And a second robot arm 9 for picking up and releasing the coded stamped parts onto the multi-station detection device 3 is provided on the multi-station coding device 2. The second robot arm 9 is a multi-axis moving robot arm, 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 two directions, namely the third direction Z and the second direction Y.

[0052] Optionally, the second robot arm 9 of this embodiment includes a gantry body, and at least part of the gantry body extends outside the first device platform 20. At this time, the second suction cup robot arm on the gantry body can move from the first device platform 20 above the multi-station detection device 3 outside the first device platform 20.

[0053] As Figure 4 As shown, the multi-station detection device 3 is a flatness detection device, which includes a second device platform 30. A number of detection positioning fixtures 31 are arranged in parallel on the second device platform 30, and each detection positioning fixture 31 has a number of stamped part fixing positions respectively. Each detection positioning fixture 31 is respectively connected to a second linear drive assembly 32. A detection assembly 33 corresponding to each detection positioning fixture 31 is also provided on the second device platform 30. The second linear drive assembly 32 also selects a linear motor group, and the detection assembly 33 is, for example, an industrial camera, etc.

[0054] Optionally, the number of stations of the multi-station coding device 2 is more than that of 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, while 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 fixtures 21 of the coding positioning fixtures 21 of the multi-station coding device 2 can perform material receiving, at least two coding positioning fixtures 21 can perform coding at the coding stations, and the remaining one coding positioning fixture 21 can be used to complete the material taking after coding, so that the whole process does not require a front and back action waiting cycle, thereby improving production efficiency.

[0055] As the detection positioning fixture 31 moves in the first direction X, the detection assembly 33 at this time can complete the detection of the stamped parts, such as flatness detection.

[0056] When the detection is completed, there are two situations for the stamped parts at this time. The first is the qualified stamped parts, and the second is the unqualified stamped parts. The qualified stamped parts are obtained by the second manipulator 9 as described above and released onto the transfer device 6, and the unqualified stamped parts are transferred and released onto 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 replenishing device 5, and the replenishing device 5 and the transfer device 6 of the present embodiment are staggeredly distributed and arranged on the multi-station detection device 3. The transfer device 6, the replenishing device 5 and the detection and positioning jig 31 of the present embodiment are spaced apart in the second direction Y. Secondly, the unqualified material output device 34 is located beside the replenishing device 5, and the unqualified material output device 34 is used to convey the unqualified stamped parts detected.

[0057] Further, as Figure 4 shown, the replenishing device 5 includes a replenishing jig 50 having a plurality of stamped part fixing positions, and a fourth manipulator 51 for obtaining and releasing the stamped parts on the replenishing jig 50 onto the transfer device 6. The replenishing jig 50 is connected to a third linear drive assembly 52. The third linear drive assembly 52 is, for example, a linear motor group, and the fourth manipulator 51 is, for example, an industrial robot with a suction cup. The replenishing jig 50 actively moves in the picking area of the fourth manipulator 51 under the drive of the third linear drive assembly 52. At this time, the multi-axis movable fourth manipulator 51 obtains the qualified stamped parts pre-placed on the replenishing jig 50 from the replenishing jig 50 and releases them onto the transfer device 6. At this time, the total number of qualified stamped parts on the transfer device 6 is equal to the set total number of stamped parts, so that the number of stamped parts obtained by the multi-material insertion transfer device 7 at one time is equal to the total number of one material position of the multi-material position storage device 4. For example, the multi-material position storage device 4 has several rows and each row has four stamped part material positions. The multi-material insertion transfer device 7 obtains four qualified stamped parts from the transfer device 6 at one time, which can prevent the stamped part material positions of the multi-material position storage device 4 from being vacant, or prevent the subsequent manual placement of the missing stamped parts.

[0058] That is, the replenishing device 5 is used to supplement the unqualified stamped parts after one-time detection by the multi-station detection device 3 and make the number of stamped parts on the transfer device 6 reach the set qualified number. As Figure 8 shown, the transfer device 6 includes a jig 60 with several stamped part transfer positions.

[0059] Specifically, as Figures 5 - 7As shown, the multi-level storage device 4 of this embodiment is a basket-type multi-level storage device, including a device frame 40. An empty basket loading mechanism 41, an empty basket orientation mechanism 42, and a loaded basket descending mechanism 43 are provided on the device frame 40. A fifth manipulator 44 is also provided on the device frame 40 for obtaining the empty basket conveyed upward by the empty basket loading mechanism 41 and releasing it to the empty basket orientation mechanism 42, and for obtaining the loaded basket after being fully loaded on the empty basket orientation mechanism 42 and releasing it to the loaded basket descending mechanism 43. And there are two fifth manipulators 44 in this embodiment, and the one-time multi-material transfer device 7 is a multi-axis manipulator, such as a multi-axis (six-axis) industrial robot, which carries four suction cups.

[0060] The empty basket orientation mechanism 42 includes a receiving fixture 420 and a drive motor 421 for driving the receiving fixture 420 to rotate. The drive motor 421 is, for example, a DD motor.

[0061] The structure of the fifth manipulator 44 is, for example: a gantry bracket 440. A linear motor assembly 441 is provided on the gantry bracket 440. A lifting frame 442 is provided on the linear motor assembly 441, and a lifting drive 443 for driving the lifting frame 442 to lift. The empty basket and the fully loaded basket are collectively referred to as the basket. An adapter frame / plate 444 that conforms to the open surface of the basket is provided on the lifting frame 442. Translation clamping parts 445 are respectively provided on the opposite sides of the lower surface of the adapter frame / plate 444, and a drive cylinder 446 connected to the translation clamping parts 445 is provided on the adapter frame / plate 444. Of course, the drive cylinder 446 can also be replaced by a drive oil cylinder. The two translation clamping parts 445 move towards each other and cooperate with the adapter frame / plate 444 to clamp the basket.

[0062] Secondly, the empty basket loading mechanism 41 of this embodiment includes an empty basket conveyor belt 410. One side of the empty basket conveyor belt 410 is the empty basket entry end. An empty basket lifting and elevating 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 elevating assembly 411 obtains the empty basket in the form of a support bracket or a grasping manipulator and walks upward in the third direction Z. When the empty basket is lifted to a set height, at this time, one of the fifth manipulators 44 is used to obtain the empty basket conveyed upward by the empty basket loading mechanism 41 and release it to the empty basket orientation mechanism 42. After the empty basket orientation mechanism 42 rotates the empty basket to a set angle, the one-time multi-material transfer device 7 obtains the equal number of stamped parts on the transfer device 6 and inserts them into the four side-by-side or parallel stamped part positions of the empty basket. Subsequently, the one-time multi-material transfer device 7 repeats the actions of obtaining and releasing and inserting until the entire empty basket is fully loaded. When the empty basket is fully loaded, the other fifth manipulator 44 is used to obtain the fully loaded basket on the empty basket orientation mechanism 42 and release it to the loaded basket descending mechanism 43.

[0063] 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.

[0064] 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 .

[0065] Preferably, the conveying direction of the loaded basket output belt 431 of this embodiment is opposite to the conveying direction of the empty basket conveyor belt 410.

[0066] like Figures 1 - 9 As shown, the processing method of the metal stamping part in this embodiment includes the following steps:

[0067] S1, stamping to obtain a stamped part, and the stamped part is transported to the output end of the conveying device 1 through the conveying device 1;

[0068] S2, transferring the stamping parts in S1 to the multi-station coding device 2, the multi-station coding device 2 performs coding processing on a plurality of stamping parts distributed in parallel, and each column has a plurality of stamping parts;

[0069] S3, transferring the stamped parts after coding in S2 to the multi-station detection device 3, the multi-station detection device 3 detects a number of stamped parts distributed in parallel to obtain qualified stamped parts and unqualified stamped parts;

[0070] S4, transfer the qualified stamping parts in S3 to the transfer device 6. When S3 detects unqualified stamping parts, obtain qualified stamping parts from the feeding device 5 and feed them to the transfer device 6, so that the total number of temporarily stored qualified stamping parts on the transfer device 6 is equal to the set number of qualified stamping parts;

[0071] S5, obtaining a plurality of qualified stamping parts on the transfer device 6 in S4 through a one-time insertion multi-material transfer device 7 and transferring and inserting them into the multi-level storage device 4;

[0072] S6. Repeat the above S1-S5 to continuously process the stamping parts.

[0073] The advantages of this embodiment are as follows:

[0074] 1. By presetting the transfer device 6 and the multi-material insertion and transfer device 7, and combining with the feeding device 5, the number of stamped parts inserted into the multi-position storage device 4 each time can reach the set quantity, eliminating the subsequent need for manual feeding and significantly improving production efficiency.

[0075] 2. Through the continuous distribution of the multi-station coding device 2, the multi-station detection device 3, and the multi-position storage device 4, and combining with the transfer device 6, continuous processing operations of the production line can be achieved, thereby improving production efficiency.

[0076] 3. Both the multi-station coding device 2 and the multi-station detection device 3 are devices that drive the stamped parts to move actively, facilitating the picking and releasing of materials by different manipulators to shorten the alternating time interval of picking and releasing materials.

[0077] 4. The basket-type multi-position storage device can be directly applied to post-processing operations such as cleaning, etc., without the need to re-stack materials in a dedicated storage device or the corresponding fixtures of the cleaning production line.

[0078] Embodiment 2

[0079] As Figure 10 and Figure 11 shown, based on Embodiment 1, this embodiment further discloses the following content: There are several empty basket conveyor belts 410 and they are arranged in sequence according to the conveying direction, and each empty basket conveyor belt 410 is driven by a drive motor respectively. Through the design of several empty basket conveyor belts 410, more empty baskets can be temporarily stored. And an empty basket conveyor belt 410 on the output side according to the conveying direction is arranged on the empty basket lifting and elevating assembly 411. At this time, the empty basket lifting and elevating assembly 411 drives the empty basket conveyor belt 410 to lift. The empty basket lifting and elevating assembly 411 is, for example, a belt-type lifting assembly. Specifically, the empty basket lifting and elevating assembly 411 includes two first rotating shafts 4110 rotatably connected to the device frame 40, and the two first rotating shafts 4110 are connected by several first synchronous belts 4111. Any one of the first rotating shafts 4110 is connected to a first motor, and the first motor is, for example, a servo motor.

[0080] One of the above-mentioned empty basket conveyor belts 410 is connected to the first synchronous belt 4111, and the empty basket conveyor belt 410 and the device frame 40 are connected by a first guiding structure 4112. The first guiding structure is, for example, a guide rail pair, etc. That is, the conveyor belt bracket of the empty basket conveyor belt 410 is fixed to the slider of the guide rail pair.

[0081] Secondly, the structure of the loading basket lifting assembly 430 is the same as that of the empty loading basket lifting assembly 411, and there are several loading basket output belts 431 distributed along the conveying direction. The loading basket output belt 431 closest to the loading basket lifting assembly 430 is fixed to the loading basket lifting assembly 430. For the specific fixing method, refer to the fixing method of the empty loading basket conveyor belt 410 described above.

[0082] When multiple empty loading baskets are palletized, the upper and lower empty loading baskets are aligned and palletized through the positioning pins and positioning holes, as well as the positioning pins and positioning grooves.

[0083] For example, the empty loading basket is defined as an upper empty loading basket and a lower empty loading basket. Positioning pins are respectively provided on the opposite sides of the top of the lower empty loading basket. One side of the opposite sides of the bottom of the upper empty loading basket is provided with positioning holes corresponding to the corresponding positioning pins one by one (with a clearance fit between the two), and the other side is provided with positioning grooves corresponding to the corresponding positioning pins one by one. In this way, rapid palletization with a certain displacement adjustment amount can be achieved.

[0084] An avoidance space is formed between the upper empty loading basket and the lower empty loading basket. For example, an avoidance space is formed between the other opposite sides of the top of the lower empty loading basket and the other opposite sides of the bottom of the upper empty loading basket for operations such as forklifting.

[0085] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
