Description
TECHNICAL FIELD
[0001] The utility model relates to mould detection technical field, concretely is a kind of detection device for automatic identification mould processing. BACKGROUND
[0002] Mould is the key tool for injection molding, blow molding, extrusion, die casting, forging, smelting, stamping and other molding processes in industrial production, and is widely used in automobile, electronics, household appliances, aerospace and other fields. The quality of mould directly affects the precision, appearance and performance of the final product, so it is very important to strictly detect the quality of mould. After mould processing is completed, comprehensive size detection and tangent detection are usually carried out on the mould by using mould detection device to ensure that it meets design specifications and process standards.
[0003] In the prior art, the detection device for mould processing first places the mould under the detection head during detection, and detects the mould by the detection head provided by the detection device. Since the mould is mostly placed directly and the stability effect is poor, the mould is prone to deviation during detection, which affects the accuracy of mould size detection. Moreover, the fixed position camera can only cover a specific detection area and cannot flexibly adjust the shooting angle and distance. For moulds with complex shapes, key parts may not be completely captured, resulting in incomplete detection and affecting the detection effect.
[0004] To solve this problem, we propose a detection device for automatic identification of mould processing. UTILITY MODEL CONTENT

[0027] To address the shortcomings of existing technologies, such as Figures 1-9 As shown, this utility model provides an automatic identification detection device for mold processing, including: a detection box 1, a door 20 and an identification mechanism 2 for QR code identification of AGV trolley are provided on one side of the detection box 1, a guide component for conveying mold 19, a first positioning mechanism 3 and a second positioning mechanism 4 for fixing the upper mold 191 and lower mold 193 of mold 19 respectively, a laser range sensor 5 is provided on the first positioning mechanism 3 and the second positioning mechanism 4, and a camera detection mechanism for detecting mold 19 is provided on one side of the positioning mechanism;
[0028] It should be noted that the identification mechanism 2 is equipped with a QR code recognition module, which is used to exchange data with the QR code on the AGV vehicle, confirm the identity and position of the AGV vehicle, and open the hatch 20 to receive the mold 19 to be inspected; the laser sensor is used to detect the specific position of the mold 19 entering the inspection box 1 and feed the data back to the controller, which controls the controller to drive the first lifting component 31 and the second lifting component 41 to operate according to the position information of the mold 19, so as to adjust the position of the first clamping component 32 and the second clamping component 42. When the mold 19 enters the inspection area through the guide component, the first clamping component 32 and the second clamping component 42 clamp and fix the upper mold 191 and the lower mold 193 of the mold 19 respectively.
[0029] The camera inspection mechanism includes an X-axis linear guide 6, a Y-axis linear guide 7, and a line scan camera 8. The upper end of the X-axis linear guide 6 is mounted on one side of the inner wall of the inspection box 1 via a first fixing plate 9. A first slider 10 is slidably mounted on the X-axis linear guide 6. A first drive motor 11 for driving the first slider 10 to slide on the X-axis linear guide 6 is mounted at one end of the X-axis linear guide 6. The upper end of the Y-axis linear guide 7 is fixedly connected to a second fixing plate 12 mounted on the bottom side of the first slider 10. A second slider 13 is slidably mounted on the Y-axis linear guide 7. A second drive motor 14 for driving the second slider 13 to slide on the Y-axis linear guide 7 is mounted at one end of the Y-axis linear guide 7. A line scan camera 8 is mounted on one side of the second slider 13 via a connecting plate. The line scan camera 8 is used to inspect the mold 19.
[0030] It should be noted that the first drive motor 11 drives the first slider 10 to slide along the X-axis linear guide rail 6, so that the entire Y-axis linear guide rail 7 and the line scanning camera 8 on it move in the X-axis direction to cover the transverse area of the mold 19, ensuring that the line scanning camera 8 can scan every column of the mold 19. The second drive motor 14 drives the second slider 13 to slide along the Y-axis linear guide rail 7, so that the line scanning camera 8 moves in the Y-axis direction to cover the longitudinal area of the mold 19, ensuring that the line scanning camera 8 can scan every row of the mold 19. During the movement, the line scanning camera 8 scans the surface of the mold 19 row by row, generating continuous image data. After the images are stitched together, the results are fed back to the control system. The control system performs real-time analysis based on the acquired data to determine whether the quality of the mold 19 meets the design specifications and process standards.
[0031] Specifically, the first positioning mechanism 3 includes a first lifting component 31 and a first clamping component 32. The first lifting component 31 is disposed at the top of the inside of the detection box 1, and the first clamping component 32 is disposed at the bottom of the first lifting component 31. The first clamping component 32 is clamped and fixed by the upper mold 191 of the mold 19.
[0032] Specifically, the second positioning mechanism 4 includes a second lifting component 41 and a second clamping component 42. The second lifting component 41 is disposed at the bottom of the inside of the detection box 1, and the second clamping component 42 is disposed at the top of the first lifting component 31. The second clamping component 42 is clamped and fixed by the lower mold 193 of the mold 19.
[0033] Specifically, the first clamping component 32 and the second clamping component 42 are used to clamp the locking blocks 194 provided on the upper mold 191 and the lower mold 193 of the mold 19, respectively;
[0034] It should be noted that the first lifting assembly 31 and the second lifting assembly 41 can be hydraulic cylinders, and the first clamping assembly 32 and the second clamping assembly 42 can be mechanical grippers to clamp the block 194.
[0035] Specifically, the guide assembly includes a base plate 17 and guide frames 15 disposed opposite to each other on both sides. The guide frames 15 are disposed on one side of the inner wall of the detection box 1. Multiple guide wheels 16 are arrayed on the inner side of the guide frames 15 in both the upper and lower horizontal directions. The upper and lower sets of guide wheels 16 are used to guide the upper mold 191 and the lower mold 193 of the mold 19, respectively.
[0036] Specifically, guide grooves 192 are provided on both sides of the bottom end of the upper mold 191 of the mold 19, and the guide grooves 192 are matched with the guide wheels 16;
[0037] It should be noted that the design of the guide frame 15 and guide wheel 16 can effectively prevent the mold 19 from shifting laterally or longitudinally during the conveying process, so as to ensure that the mold 19 is conveyed to the detection area according to the preset trajectory and avoid detection errors caused by position deviation.
[0038] Specifically, the detection box 1 has two doors 18 connected by hinges on the side away from the hatch 20.
[0039] In summary, the basic working principle of this utility model is as follows: After the identification mechanism 2 detects the AGV trolley, the detection device automatically opens the hatch 20 to allow the AGV trolley box detection device to transport the mold 19 to be detected. The mold 19 enters the detection box 1 through the base plate 17 and the guide frames 15 on both sides to be transported to the detection area. The laser ranging sensor 5 monitors the specific position of the mold 19 in real time. The controller controls the operation of the first lifting assembly 31 and the second lifting assembly 41, adjusts the first clamping assembly 32 and the second clamping assembly 42 to clamp and fix the mold 19, the camera detection mechanism is started, and the X-axis linear guide 6 and the Y-axis linear guide 6 are activated. Driven by the first drive motor 11 and the second drive motor 14, the line scanning camera 8 scans the surface of the mold 19 line by line on the track 7, generating continuous image data. After the image data is stitched together, it is analyzed in real time by the control system to determine whether the quality of the mold 19 meets the design specifications and process standards. After the inspection is completed, the control system sends a signal, the first clamping component 32 and the second clamping component 42 release the mold 19, the AGV trolley transports the mold 19 out of the inspection box 1, the first lifting component 31 and the second lifting component 41 return to their initial positions, and the door 20 closes to inspect the next mold 19.
