[0018] 1. The present invention aims to solve the problem that the adsorption, transportation and stacking of adsorption manipulators cannot synchronously complete surface defect detection, and the flipping action included therein causes the side of the engine cover to touch the bottom first and is very likely to be damaged by collision. On the one hand, the present invention first completes the classification of the appearance surface defect detection of the engine cover through the control system, and then completes the corresponding conveying and stacking control signal output according to the classified engine cover; on the other hand, the engine cover is controlled to form conveying and stacking corresponding to the classification information in combination with the classification information, and the stacking of the engine cover stamping parts is realized through the steering control that integrates flipping, conveying and stacking, which finally solves the problem that the adsorption, transportation and stacking of adsorption manipulators cannot synchronously complete surface defect detection, and the flipping action causes the side of the engine cover stamping parts to be damaged by collision;

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1: In view of the problem that the adsorption and transportation of the adsorption manipulator cannot synchronously complete the surface defect detection, and the flipping action involved causes the side of the engine cover to touch the bottom first and easily cause collision damage, the following technical solution is proposed:

[0041] Reference Figure 1 - Fig.10 As shown, in this embodiment, an automatic stacking device for stamping parts for engine hood processing comprises a receiving rack 1 and a feeding rack 2 arranged on the same horizontal plane, the feeding rack 2 is externally embedded with a control panel, one end of the receiving rack 1 is equipped with a flipping assembly 3 for flipping the engine hood, the other end of the receiving rack 1 is equipped with a conveying assembly 4 for feeding the flipped engine hood, and both sides of the end of the feeding rack 2 are equipped with positioning and clamping assemblies 5; the flipping assembly 3 comprises a bottom plate 301 and an adsorption plate 303, and an adsorption disk 304 connected to an exhaust source is installed through the bottom plate 301 and the adsorption plate 303, and a base plate 10 connected to the bottom plate 301 is vertically slidably installed at the feeding front end of the receiving rack 1; the positioning and clamping assembly 5 comprises a fixed pressure plate 501 rotatably arranged on the outside of the feeding rack 2, and one end of the fixed pressure plate 501 away from the hinge extends to between the feeding racks 2, and the fixed pressure plate 501 is made of rubber material and will not cause compressive damage to the engine hood;

[0042] Reference Figure 2 and Figure 8 As shown, a feeding roller 29 connected to the conveying roller 401 is provided between the feeding racks 2, and a stacking assembly 6 is installed at the end of the feeding rack 2 corresponding to the feeding roller 29, and the stacking assembly 6 includes a lifting platform 7 and a stacking plate 601 provided at the lifting end of the lifting platform 7;

[0043] Reference Figure 7 and Figure 8 As shown, the positioning and pressing assembly 5 also includes an electric push rod 504 hingedly arranged on the outside of the top cover 8, and the electric push rod 504 can drive the fixed pressure plate 501 to rotate and press on the engine cover after the stacking is completed to achieve stability;

[0044] It is important to note that the flipping-conveying-stacking action includes the following steps: (1) first, the suction plate 303 is in a state of overlapping with the conveying roller 401. When the stamping part slides onto the suction plate 303, the engine cover can be adsorbed outside the suction plate 303 through the adsorption effect of the adsorption disk 304 connected to the air extraction source, and then the driving structure is started to drive the stamping part to flip 180 degrees;

[0045] (2) After the stamping part is turned over 180°, it slowly falls off the conveying roller 401 and is horizontally conveyed to the stacking plate 601 by the conveying roller 401 and the feeding roller 29;

[0046] (3) After the engine cover stamping parts are collected, they are positioned and pressed by the fixed pressure plates 501 symmetrically arranged on both sides, and finally transferred at a short distance for deep processing such as surface treatment;

[0047] The control panel has a built-in control system, which is communicatively connected with a control unit, an image acquisition unit, an evaluation and analysis unit, and a processor, and a camera is arranged above the feeding direction of the engine cover to capture an overhead image of the engine cover during the feeding process;

[0048] The image acquisition unit is used to collect overhead images and send them to the evaluation and analysis unit through the processor for analysis to obtain evaluation information, and compare the evaluation information with the normal appearance of the engine cover preset in the processor to classify the defective engine cover and send it to the control unit;

[0049] The control unit performs startup control according to the classification information of the engine cover. The control unit is used to control the feed roller 29 and the electric push rod 504 to perform the following actions:

[0050] Action 1: When the engine cover on the conveying roller 401 has appearance defects, the conveying roller 401 normally conveys the engine cover to the feeding roller 29, and the feeding roller 29 stops after receiving all the engine covers. At this time, the engine cover on the feeding roller 29 is sucked out separately by the adsorption manipulator, thereby completing the removal of the engine cover with appearance defects, avoiding entering the normal stacking link to affect the subsequent smooth processing;

[0051] Action 2: When the engine cover on the conveying roller 401 has no appearance defects, the feeding roller 29 continues to convey the engine cover until all of them fall onto the stacking plate 601. At this time, the position of the stacking plate 601 on the lifting platform 7 is determined according to the number of engine covers that have fallen, and then the electric push rod 504 is started, and the electric push rod 504 drives the fixed pressure plate 501 to flip inward until it contacts the engine cover on the stacking plate 601 and completes the fixation;

[0052] Reference Figure 3As shown, the upper end of the base plate 10 is symmetrically mounted with a bearing seat 11, the bottom end of the bottom plate 301 is rotatably mounted on the bearing seat 11, a turntable 302 connected to the bottom plate 301 is mounted between the bearing seats 11 via a rotating rod, and a driving structure for driving the turntable 302 to rotate is arranged outside the bearing seat 11, and the driving structure is a conventional driving motor, which drives the adsorption plate 303 and the adsorption disk 304 to complete the deflection action, thereby achieving the purpose of flipping the engine cover;

[0053] Basic principle: When feeding the engine hood after appearance defect detection based on visual analysis, on the one hand, the control system first completes the classification of the appearance surface defect detection of the engine hood, and then completes the corresponding conveying and stacking control signal output according to the classified engine hood; on the other hand, the engine hood is controlled in combination with the classification information to form the conveying and stacking corresponding to the classification information, and the stable stacking of the engine hood stamping parts is achieved through the steering control that integrates flipping, conveying and stacking.

[0054] Embodiment 2: This embodiment further optimizes the process of how to stabilize the stacking of the engine cover stamping parts after the appearance defect detection in Embodiment 1:

[0055] Reference Figure 7 - Fig.10 As shown, it includes: a fork hole 602 is opened on the stacking plate 601, a lifting frame 28 is vertically slidably installed on the lifting end of the lifting platform 7, and the lifting frame 28 is connected to the rear side of the stacking plate 601. Rotating grooves 9 for rotating the fixed pressure plate 501 are opened on both sides of the top cover 8. The fixed pressure plate 501 rotates to the upper side of the two sides of the stacking plate 601 through the rotating grooves 9. A plurality of rotating seats 503 are installed on the outer side of the feeding frame 2, and a rotating rod 502 connected to the fixed pressure plate 501 is rotatably installed between the rotating seats 503. A clamping sleeve 506 is installed on the outer end of the rotating rod 502, and a deflection rod 505 fixedly connected to the clamping sleeve 506 is hinged at the output end of the electric push rod 504;

[0056] It is important to note that: the engine cover stamping parts after appearance defect detection are normally transported to the stacking plate 601, and the fork bar hole 602 provided on the stacking plate 601 is used to match the lifting fork of the forklift. After the stacking is completed, the engine cover stamping parts are uniformly transported to the surface treatment station by the forklift, thereby reducing the transportation demand after the engine cover stamping parts are processed. In combination with the first embodiment, after a series of processes such as flipping, appearance defect detection and stacking, the engine cover stamping parts are directly "ferryed" at a short distance by the forklift, thereby reducing the probability of damage to the engine cover stamping parts;

[0057] Reference Figure 2 - Figure 6As shown, the conveying assembly 4 includes a roller frame 101 arranged on one side of the receiving frame 1, and a chassis 102 is installed on the other side of the receiving frame 1. A conveying roller 401 is installed at the upper end between the roller frame 101 and the chassis 102, and the outer cover of the conveying roller 401 is provided with evenly distributed gaskets 402. A pair of symmetrically distributed wheel seats 16 are installed on the lower side of the front end of the feeding side of the receiving frame 1, and a pulley 17 is rotatably installed on the wheel seat 16. A synchronous belt 18 is sleeved between the pair of pulleys 17, and clamping blocks 19 are respectively installed on the upper and lower layers of the synchronous belt 18. A hook seat 20 extending to the bottom of the conveying roller 401 is installed at the rear end of the clamping block 19, and a clamping rod 21 extending to the gap between the conveying roller 401 is installed on the hook seat 20;

[0058] In addition, during the conveying process, the limiting structure composed of the synchronous belt 18, the hook seat 20 and the clamping rod 21 can effectively prevent the engine cover stamping part from shifting during the conveying process, and can be adapted to engine covers of different sizes for use, so that the camera can take a more comprehensive overhead image to complete a comprehensive appearance defect detection;

[0059] Reference Figure 4 and Figure 5 As shown, a mounting frame 24 is provided on the rear side of one of the wheel seats 16, and a photoelectric sensor 25 is installed on the mounting frame 24. A turntable 27 opposite to the photoelectric sensor 25 is installed on the portion of the synchronization rod 26 of the pulley 17 extending to the mounting frame 24. In the process of stacking the engine cover stamping parts, a single flipping action performed by the flipping assembly can be measured by a single rotation of the photoelectric sensor 25 and the turntable 27. After counting, the information is stored and compared with the subsequent deep processing of the engine cover to achieve the purpose of information traceability.

[0060] Embodiment 3: Based on the technical contents of Embodiment 1 and Embodiment 2, the process and principle of the present invention are as follows:

[0061] Initial state: At this time, the adsorption plate 303 is in a state of overlapping with the conveying roller 401. When the stamping part slides onto the adsorption plate 303, the engine cover can be adsorbed outside the adsorption plate 303 through the adsorption effect of the adsorption disk 304 connected to the air extraction source;

[0062] During flipping: after the engine cover stamping parts stamped by the stamping equipment are placed outside the adsorption plate 303, the driving structure drives the adsorption plate 303 to deflect 180°, thereby rotating the stamping parts onto the conveying roller 401. According to the initial placement position, the limiting structure composed of the synchronous belt 18, the hook seat 20 and the clamping rod 21 is started, which can effectively prevent the engine cover stamping parts from deviating during the conveying process on the conveying roller 401 and the feeding roller 29, and can be adapted to engine covers of different sizes for use;

[0063] During stacking: the feed roller 29 continues to transport the engine cover until all of them fall onto the stacking plate 601. At this time, the position of the stacking plate 601 on the lifting platform 7 is determined according to the number of engine covers that have fallen in. Then the electric push rod 504 is started, and the electric push rod 504 drives the fixed pressure plate 501 to flip inward until it contacts and fixes the engine cover on the stacking plate 601. The fork bar hole 602 provided on the stacking plate 601 is used to match the lifting fork of the forklift. After the stacking is completed, the forklift will unify the engine cover stamping parts and then transport them to the surface treatment station, thereby reducing the transportation requirements after the engine cover stamping parts are processed.

[0064] In summary: On the one hand, the present invention first completes the classification of the appearance surface defect detection of the engine hood through the control system, and then completes the corresponding conveying and stacking control signal output according to the classified engine hood; on the other hand, the classification information of the engine hood is combined to control the engine hood to form conveying and stacking corresponding to the classification information, and the stacking of the engine hood stamping parts is realized through the steering control that integrates flipping, conveying and stacking, which finally solves the problem that the surface defect detection cannot be completed synchronously through the adsorption, transportation and stacking of the adsorption robot, and the flipping action causes collision damage to the side of the engine hood stamping parts.
