[0003] Die casting refers to a casting method in which molten or semi-molten metal is injected into a metal mold at high speed and crystallized under pressure. It is referred to as die casting. The engine bracket is cast by a die casting machine under high pressure. After the die casting is completed, the engine bracket needs to be removed by a robot.

The staff also needs to classify the unqualified engine brackets into repairable engine brackets and unrepairable engine brackets. The subsequent inspection steps are numerous and complicated, which wastes manpower.

The extension and retraction of the output end of the hydraulic cylinder 12 is used to control the up and down movement of the clamp 14. The extension and retraction of the two output ends of the double-headed hydraulic cylinder 13 are used to clamp the engine bracket and lower the engine bracket. The robotic arm 2 refers to a high-precision, multi-input and multi-output, highly nonlinear, and strongly coupled complex system. Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof and other fields.

[0023] Specifically, the air pump 16 is used to extract the gas inside the air box 15 and spray it onto the surface of the engine bracket from the output port of the injection pipe 17. The initial injection pipe 17 is aligned with the engine bracket. After the motor 10 controls the rotating block 11 to rotate one hundred and eighty degrees clockwise, the clamp 14 is aligned with the engine bracket.

[0024] A failed box 5 is provided at the rear side of the base 1 , and a passed box 4 is provided at the front side of the base 1 .

[0026] A plurality of partitions are evenly and fixedly connected inside the unqualified box 5 , and the interior of the unqualified box 5 is divided into a first scrap chamber 6 , a second scrap chamber 7 , a third scrap chamber 8 , and a pitting chamber 9 in sequence by the partitions.

[0028] An identification and clamping system is provided inside the control box 3. The identification and clamping system includes a detection module, a clamping module, and a flushing module. The detection module, the clamping module, and the flushing module are connected to each other by signals.

[0029] The detection module is connected with the camera 18 and the X-ray machine signal, the clamping module is connected with the robot arm 2, the motor 10, the hydraulic cylinder 12, and the double-head hydraulic cylinder 13 signal, and the flushing module is connected with the air pump 16 signal.

[0030] A database is provided inside the control box 3, and identification photos of engine brackets of different lengths and identification photos of engine brackets of different degrees of defects are stored inside the database.

[0031] Specifically, the camera 18 is used to capture images of the surface of the engine bracket, and convert the captured images into electrical signals and transmit them to the control box 3. When the control box 3 receives the photos sent by the camera 18, it will first compare the photos with the identification photos of engine brackets of different lengths in the internal database of the control box 3, and pre-identify the length of the engine bracket. Based on the obtained photos of the engine bracket, the engine bracket is divided into a large bracket and a small bracket. The photos sent by the camera 18 are then compared with the identification photos of engine brackets of different degrees of defects in the internal database of the control box 3 to identify the defects on the surface of the engine bracket. The degree of defect of the engine bracket is determined, and the degree of defect of the engine bracket is divided into irreparable and unrepairable according to the photographs of the engine bracket obtained. The X-ray machine is used to photograph and image the inside of the engine bracket, and convert the photographed image into an electrical signal and transmit it to the control box 3. When the control box 3 receives the photo sent by the X-ray machine, the photo sent by the X-ray machine is compared with the identification photos of engine brackets with different degrees of defect in the internal database of the control box 3 to identify the degree of defect inside the engine bracket, and the degree of defect of the engine bracket is divided into scrap, no need for repair and pitting repair according to the photographs of the engine bracket obtained.

[0032] The following steps are involved:

[0033] S1: The jet pipe 17 is used to blow air to clean the surface of the engine bracket;

[0034] Specifically, after the die-casting of the engine bracket is completed, the control box 3 controls the robotic arm 2 to align the injection pipe 17 with the engine bracket, and the air pump 16 extracts the air inside the air box 15 and sprays it to the engine bracket from the output end of the injection pipe 17, blowing away the dust on the surface of the engine bracket, making the subsequent photos taken by the camera 18 clearer, thereby improving the accuracy of the camera 18 taking pictures.

[0035] S2: The output end of the motor 10 rotates to align the camera 18 with the engine bracket, and the camera 18 takes a picture of the engine bracket;

[0036] Specifically, the output end of the motor 10 rotates clockwise to control the rotating block 11 to rotate 180 degrees, so that the camera 18 is aimed at the engine bracket. The camera 18 is turned on to capture an image of the engine bracket and converts the captured image into an electrical signal to be transmitted to the control box 3.

[0037] S3: According to the photo of the engine bracket taken by the camera 18, a photo of the engine bracket with the same length is matched from the database, so as to control the retraction length of the output end of the double-headed hydraulic cylinder 13;

[0038] Specifically, when the control box 3 receives the photo sent by the camera 18, it will first compare it with the identification photos of engine brackets of different lengths in the internal database of the control box 3, pre-identify the length of the engine bracket, and divide the engine bracket into a large bracket and a small bracket according to the obtained photograph of the engine bracket. The control box 3 sends the length of the output end that needs to be retracted to the double-headed hydraulic cylinder 13, so as to accurately clamp the engine bracket. Assume that the length of the large engine bracket is 50cm, the length of the small engine bracket is 30cm, and the distance between the two clamps is 60cm. When the camera 18 takes a photo of the engine bracket and the control box 3 is matched as a large engine bracket, the two output ends of the double-headed hydraulic cylinder 13 are retracted by 5cm respectively, and the control clamp 14 is controlled to clamp it accurately. When the camera 18 takes a photo of the engine bracket and the control box 3 is matched as a small engine bracket, the two output ends of the double-headed hydraulic cylinder 13 are retracted by 15cm respectively, and the control clamp 14 is controlled to clamp it accurately. There is no need to modify the retraction process of the output end of the double-headed hydraulic cylinder 13 multiple times before clamping engine brackets of different sizes, thereby achieving the effect of accurate clamping.

[0039] S4: According to the photo of the engine bracket taken by the camera 18, a photo of the engine bracket with the same degree of defect is matched from the database, so as to control the robot arm 2 to send the engine bracket to the designated position.

[0040] Specifically, after comparing the photos sent by the camera 18 with the identification photos of the engine brackets of different lengths in the internal database, the photos sent by the camera 18 are compared with the identification photos of the engine brackets of different degrees of defects in the internal database of the control box 3 to identify the degree of defects of the engine bracket, and the degree of defects of the engine bracket is divided into irreparable and X-ray machine detection according to the obtained photographs of the engine bracket. The X-ray machine then photographs and images the inside of the engine bracket, and converts the photographed image into an electrical signal and transmits it to the control box 3. When the control box 3 receives the photos sent by the X-ray machine, the photos sent by the X-ray machine are compared with the identification photos of the engine brackets of different degrees of defects in the internal database of the control box 3 to identify the degree of defects inside the engine bracket, and the degree of defects of the engine bracket is divided into scrap, no need for repair and pitting repair according to the obtained photographs of the engine bracket.

[0041] If the image of the engine bracket taken by the camera 18 has pores on its surface, the control box 3 determines that it cannot be repaired; if the image of the engine bracket taken by the camera 18 has sand holes on its surface, the control box 3 determines that it cannot be repaired; if the X-ray machine inspection taken by the camera 18 has only pitting defects and the number is not within the standard range, the control box 3 determines that it cannot be repaired; if the image of the engine bracket taken by the camera 18 has only pitting defects and the number is within the standard range, the control box 3 determines that it is an X-ray machine inspection; if the number of pores, sand holes and pitting on the surface of the engine bracket taken by the camera 18 is zero, the control box 3 determines that it is an X-ray machine inspection;

[0042] When the control box 3 detects that the engine bracket is beyond repair, the mechanical arm 2 moves the engine bracket to the top of the second scrap chamber 7, and the control box 3 controls the output end of the double-head hydraulic cylinder 13 to extend, thereby placing the engine bracket into the first scrap chamber 6;

[0043] When the control box 3 detects that the engine bracket is for X-ray inspection, the robot arm 2 moves the engine bracket to the X-ray machine for inspection. If there is any pore or sand hole inside the image of the engine bracket taken by the X-ray machine, the control box 3 determines that it is scrapped. If the number of pores, sand holes and pits inside the image of the engine bracket taken by the X-ray machine is zero, the control box 3 determines that it does not need to be repaired. If the number of pores, sand holes and pits inside the image of the engine bracket taken by the X-ray machine is zero, and there are only pitting defects on the surface and the number is within the standard range, the control box 3 determines that the pitting needs to be repaired.

[0044] When the control box 3 detects that the engine bracket is scrapped, the mechanical arm 2 moves the engine bracket from the X-ray machine to the top of the second scrap chamber 7, and the control box 3 controls the output end of the double-head hydraulic cylinder 13 to extend, thereby placing the engine bracket into the second scrap chamber 7;

[0045] When the control box 3 detects that the engine bracket does not need to be repaired, the mechanical arm 2 moves the engine bracket from the X-ray machine to the top of the qualified box 4, and the control box 3 controls the output end of the double-headed hydraulic cylinder 13 to extend, thereby placing the engine bracket into the qualified box 4;

[0046] When the control box 3 detects that the engine bracket is for pitting repair, the mechanical arm 2 moves the engine bracket from the X-ray machine to above the pitting cavity 9, and the control box 3 controls the output end of the double-head hydraulic cylinder 13 to extend, thereby placing the engine bracket into the pitting cavity 9;

[0047] By providing a camera 18, a robotic arm 2, a control box 3, a hydraulic cylinder 12 and a double-head hydraulic cylinder 13, after the die-casting of the engine bracket is completed, the camera 18 takes a photo of the engine bracket, compares it with the identification photos of engine brackets with different degrees of defects in the internal database, identifies the degree of defect of the engine bracket, and clamps the engine bracket to a position that matches it, and automatically classifies the engine brackets with different degrees of defects without the need for manual selection and sorting by personnel, thereby achieving the effect of automatic detection of defect degrees and intelligent screening and classification.
