Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to an automatic scanning device for mold surface defects based on machine vision. Background Technology

[0002] A mold is a tool or device used to shape various materials (such as metals, plastics, glass, ceramics, etc.) into specific shapes and sizes. It plays a crucial role in industrial production and is widely used in various sectors of the manufacturing industry, including but not limited to automobile manufacturing, electronics, packaging, construction, and consumer goods production. During the mold production process, it is necessary to inspect the mold surface for defects.

[0003] Existing automatic mold surface defect scanning devices typically transport the mold to the scanner via a conveyor belt for inspection. However, after one side of the mold is inspected, it needs to be manually flipped over before being transported to the scanner for inspection of the other side, which is time-consuming and labor-intensive, resulting in low mold scanning efficiency.

[0004] Therefore, a machine vision-based automatic mold surface defect scanning device has been developed that can automatically and continuously scan both sides of the mold for defects, saving manpower and improving mold scanning efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing automatic mold surface defect scanning devices, which require manual flipping of the mold after one side is inspected before being transported to the scanner for inspection of the other side, resulting in low efficiency due to time and labor consumption, this invention provides a machine vision-based automatic mold surface defect scanning device that can automatically and continuously scan defects on both sides of the mold, saving manpower and improving mold scanning efficiency.

[0006] The technical solution of this utility model is as follows: an automatic scanning device for mold surface defects based on machine vision, comprising a support frame, a first motor, a first roller, a first conveyor belt, a scanner, a fixed frame, an electric push rod, a clamping plate, a flipping assembly, and a protective assembly. The support frame has a first motor connected to the front sides of both the left and right sides. Multiple first rollers are rotatably connected to the upper part of the support frame. The output shaft of the first motor on the left side is connected to the leftmost first roller, and the output shaft of the first motor on the right side is connected to the rightmost first roller. A first conveyor belt is wound between the four first rollers on the left side, and also between the four first rollers on the right side. Scanners are connected to both the left and right sides of the support frame. Two fixed frames are connected to the front and rear sides of the support frame, each located to the right of an adjacent scanner. Electric push rods are connected to each fixed frame, and clamping plates are connected to the telescopic ends of the electric push rods. A flipping assembly capable of flipping the mold is provided on the support frame, and a protective assembly capable of protecting the mold is provided on the flipping assembly.

[0007] In one embodiment, the clamping plates are provided with soft pads.

[0008] In one embodiment, the flipping assembly includes a belt, a second roller, a second conveyor belt, a second motor, and a flipping frame. The support frame is rotatably connected to two second rollers on the left and right sides. The second roller on the right side is connected to the adjacent first roller by a belt through a transmission wheel. The two second conveyor belts are connected to each other in the front and rear. The support frame is connected to the front side of the middle section. The flipping frame is connected to the output shaft of the second motor. The flipping frame is rotatably connected to the support frame.

[0009] In one embodiment, the flipping frame is I-shaped.

[0010] In one embodiment, the protective component includes a sleeve, a buffer frame, and an elastic element. Multiple sleeves are connected to both the left and right sides of the middle of the flip frame. Buffer frames are slidably connected between the sleeves on the same side, and elastic elements are connected between each sleeve and the connected buffer frame.

[0011] In one embodiment, the elastic element is a telescopic spring.

[0012] Beneficial effects: 1. By starting the second motor, the flipping frame is rotated and the mold is flipped to the left side of the second conveyor belt, so that the back of the mold is facing up. Then the mold is transported to the first conveyor belt on the left side, and the back of the mold is scanned by the scanner on the left side. This achieves the effect of automatically and continuously scanning defects on both sides of the mold, saving manpower and improving the efficiency of mold scanning.

[0013] 2. When the mold is conveyed to the tilting frame, the mold comes into contact with the buffer frame. The pressure buffer frame slides on the sleeve. The force of the telescopic spring keeps the buffer frame in a relative position, thus achieving the effect of buffering and protecting the mold and avoiding damage to the mold.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] An automatic scanning device for surface defects in molds based on machine vision, such as Figures 1-4 As shown, the device includes a support frame 1, a first motor 101, first rollers 2, a first conveyor belt 3, a scanner 4, a fixing frame 5, an electric push rod 6, a clamping plate 7, a flipping assembly, and a protective assembly. The first motor 101 is connected to the front sides of both the left and right sides of the support frame 1. Eight first rollers 2 are rotatably connected to the upper part of the support frame 1. The output shaft of the first motor 101 on the left side is connected to the leftmost first roller 2, and the output shaft of the first motor 101 on the right side is connected to the rightmost first roller 2. The four first rollers 2 on the left side are connected in a loop. The first conveyor belt 3 is present, and the four first rollers 2 on the right side are also connected to the first conveyor belt 3. The scanners 4 are connected to both the left and right sides of the support frame 1. The two fixed frames 5 are connected to the front and rear sides of the support frame 1. The fixed frames 5 are all located to the right of the adjacent scanners 4. The electric push rods 6 are connected to the fixed frames 5. The clamping plates 7 are connected to the telescopic ends of the electric push rods 6. The clamping plates 7 are provided with soft pads to avoid damaging the mold. The support frame 1 is provided with a flipping assembly, and the flipping assembly is provided with a protective assembly.

[0021] like Figure 1 and Figure 3 As shown, the flipping assembly includes a belt 8, a second roller 9, a second conveyor belt 10, a second motor 11, and a flipping frame 12. The support frame 1 is rotatably connected to the left and right second rollers 9 in the middle. The second roller 9 on the right side is connected to the adjacent first roller 2 by the belt 8 through a transmission wheel. The second rollers 9 are connected to each other by two second conveyor belts 10 in the front and rear. The support frame 1 is connected to the front side of the middle of the support frame 1. The output shaft of the second motor 11 is connected to the flipping frame 12. The flipping frame 12 is rotatably connected to the support frame 1. The flipping frame 12 is I-shaped to facilitate the flipping of the mold.

[0022] like Figure 1 and Figure 4As shown, the protective assembly includes a sleeve 13, a buffer frame 14, and an elastic element. Two sleeves 13 are connected to the left and right sides of the middle of the flip frame 12. The buffer frame 14 is slidably connected between the sleeves 13 on the same side. An elastic element, which is a telescopic spring 15, is connected between each sleeve 13 and the buffer frame 14.

[0023] When using this invention, firstly, the support frame 1 is placed in the automatic defect scanning area on the mold surface. Then, the mold to be scanned is placed on the first conveyor belt 3 on the right. After placement, the first motor 101 is started, driving the first roller 2 to rotate, causing the first conveyor belt 3 to rotate and transport the mold to the left. The scanner 4 on the right scans the front of the mold for defects. When the mold enters below the scanner 4, the electric push rod 6 on the fixing frame 5 can be activated to drive the clamping plates 7 to move closer together, adjusting the mold to a centered position for easy scanning. While the first roller 2 rotates, the second roller 9 is driven to rotate through the belt 8, causing the second conveyor belt 10 to rotate. After the front of the mold is scanned, it continues to be transported to the second conveyor belt 10 to the left. The mold is conveyed to the left by the second conveyor belt 10 onto the flipping frame 12. Then, the second motor 11 is started, which drives the flipping frame 12 to rotate, flipping the mold to the left side of the second conveyor belt 10 so that the back of the mold faces upward. The mold is then conveyed to the first conveyor belt 3 on the left side, where the scanner 4 on the left side scans the back of the mold. This achieves automatic and continuous defect scanning of both sides of the mold, saving manpower and improving mold scanning efficiency. When the mold is conveyed onto the flipping frame 12, it contacts the buffer frame 14, squeezing the buffer frame 14 to slide on the sleeve 13. The force of the telescopic spring 15 keeps the buffer frame 14 in a relative position, thus providing buffer protection for the mold and preventing damage to the mold.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
