Description

Technical Field

[0001] This invention belongs to the field of appearance inspection of new material castings, specifically relating to an appearance inspection device for new material castings used in a die-casting production line. Background Technology

[0002] The appearance inspection device for new material castings in the die casting production line uses an industrial camera to capture high-definition images of the surface of the new material castings. The captured images are then sent to a computer terminal, which automatically compares these photos with a standard qualified product template through preset image processing programs such as grayscale comparison and contour matching to determine whether there are defects such as pores, cracks, and burrs on the surface, thereby improving the quality and effectiveness of the inspection.

[0003] Patent CN217954286U discloses a die-casting appearance inspection device, including: a frame, a material table, at least one material suction mechanism, a material support mechanism, and an image acquisition mechanism. The material suction driver drives the material suction slider to slide above the material table, and the downward pressure driver drives the suction cup to move downwards, allowing the suction cup to pick up the die-casting. The material suction driver then drives the material suction slider to move closer to the material support mechanism. Driven by the support driver, the support frame moves closer to the material suction guide rail. The material suction slider slides above the support frame, and the suction cup moves downwards under the downward pressure driver, placing the die-casting on the support frame. Driven by the support driver, the support frame slides below the image acquisition mechanism to acquire an image. A computer analyzes the acquired image to detect whether the die-casting has defects. The accurate suction and release of the material suction mechanism ensures that the inspected die-casting can be accurately returned, avoiding interference with the die-casting's transport.

[0004] The above-mentioned device also has the following problems: When the appearance inspection device inspects the new material castings on the die-casting production line, it is necessary to adjust the position of the camera lens to align with the new material castings. Due to camera shake when adjusting the position of the camera lens, the high-definition image of the surface of the new material castings captured by the camera is not clear, resulting in poor comparison inspection effect of the appearance inspection device. Summary of the Invention

[0005] The purpose of this invention is to provide a new material casting appearance inspection device for die casting production lines, in order to solve the problem that when adjusting the camera lens position, camera shake causes the high-definition image of the surface of the new material casting to be unclear, resulting in poor comparative inspection effect of the appearance inspection device.

[0006] To achieve the above objectives, the present invention provides a new material casting appearance inspection device for a die-casting production line, comprising: A vertical frame is provided with a chassis on the back. A sliding groove is provided on the right side of the chassis. A drive frame is provided inside the chassis. A threaded rod is rotatably installed inside the drive frame. A carrier plate is slidably installed on the outer wall of the threaded rod of the drive frame. The inner wall of the carrier plate meshes with the inner wall of the threaded groove of the threaded rod. A plate is fixed to the right side of a carrier plate. A servo motor is fixedly installed on the top surface of the plate. A camera body is fixed to the bottom surface of the output end of the servo motor. A lens is fixedly installed on the right side of the camera body. The carrier plate slides up and down in the threaded groove of the threaded rod and slides up and down in the slide groove of the chassis. The carrier plate drives the plate to move up and down, and the plate drives the servo motor and the camera body to move up and down. The camera body follows the new material casting on the transport line to take pictures and automatically sends the high-definition image of the new material casting to the computer terminal. The high-definition image of the new material casting is compared with the standard new material casting photo template. A sleeve is fixed to the left side of a carrier plate. The carrier plate moves the sleeve downwards, limiting the downward movement distance of the sheet. A semi-circular block is fixed to the upper left side of the camera body. A fork is hinged to the outer wall of the semi-circular block, and a cylinder is slidably installed on the outer wall of the fork. A shaft disc is mounted through and rotatably on the top surface of a carrier plate. The outer wall of the shaft disc is fixedly connected to the inner wall of a cylinder. A spring is provided between the top of the shaft disc and the top surface of the carrier plate. Under the constraint of the carrier plate, the fork rotates on the semi-circular block and slides in the cylinder. The cylinder drives the shaft disc to rotate, and the shaft disc rotates in the carrier plate. The shaft disc drives the spring to rotate, and the spring is twisted and deformed.

[0007] According to the above technical solution, the vertical frame is located on the left side of the casting transport platform, the back of the chassis has a cabinet door, the bottom surface of the drive frame is provided with a servo motor II, the output end of the servo motor II is fixedly connected to the bottom surface of the threaded rod, and the carrier plate is slidably installed on the inner wall of the slide groove of the chassis.

[0008] According to the above technical solution, a rubber pad is provided on the bottom surface of the sleeve, the semi-circular block is located below the plate, and the fork is located to the left of the semi-circular block.

[0009] According to the above technical solution, the outer wall of the carrier plate is provided with a storage device, which is used to protect the lens of the camera body; the front and back of the camera body are provided with lens pressing devices, which are used to fasten the lens of the camera body.

[0010] According to the above technical solution, the storage device includes: A rectangular frame is fixed to the top surface of a carrier plate, and a frame arc plate is fixed to the bottom surface of the frame; A dual-axis frame is provided, which is slidably installed on the lower left side of the inner wall of the chassis. A baffle is embedded on the right side of the dual-axis frame, and a foam pad is provided in the middle of the left side of the baffle.

[0011] According to the above technical solution, the square frame is fitted outside the carrier plate, the frame of the dual-axis frame is triangular in structure, the top surface of the dual-axis frame is on the movement trajectory of the bottom surface of the frame arc plate, the square frame drives the frame arc plate to move downward, the frame arc plate and the surface of the dual-axis frame come into contact, the frame arc plate squeezes the dual-axis frame, the dual-axis frame slides to the right in the chassis, the dual-axis frame drives the baffle to slide to the right, and the camera main lens descends to the left of the foam pad.

[0012] According to the above technical solution, a notch is provided in the middle of the right side of the frame of the dual-axis frame. A second spring is fixed to the right side of the inner wall of the notch. A connecting plate is fixed to the end of the second spring away from the notch. The connecting plate is fixed to the lower left side of the inner wall of the chassis. When the notch presses the second spring to the left, the second spring contracts and stores energy. When the frame arc plate leaves the surface of the dual-axis frame, the second spring releases its elastic force.

[0013] According to the above technical solution, the mirror pressing device includes: Two strips are fixed to the front and back of the camera body. A light shield is embedded in the right side of the two strips. The strips drive the light shield to rotate, so that the light shield blocks the backlight in front of the camera body lens. A dual-axis plate, which is slidably mounted on the top surface of a light-shielding plate, and an arc-shaped spring piece is provided between the top of the inner end of the dual-axis plate and the top surface of the light-shielding plate; A rubber sheet is fixed to the bottom surface of a double-axis plate. The strip drives the light-shielding plate to rotate, so that the light-shielding plate blocks the backlight in front of the camera lens.

[0014] According to the above technical solution, the light shield is set to tilt upwards, and the rubber plate is set above the lens of the camera body.

[0015] According to the above technical solution, a double ring frame is provided below the outer wall of the double-axis plate, and a fill light is fixedly installed on the front of the double ring frame. The double-axis plate drives the double ring frame to rotate, and the double ring frame drives the fill light to rotate. The fill light follows the rotation of the camera lens.

[0016] The beneficial effects of this invention are: 1. The main lens of the camera can follow the new material castings on the transport line to take pictures, ensuring that the camera captures high-definition images of the new material castings. The camera automatically sends the high-definition images of the new material castings to the computer terminal. The high-definition images of the new material castings are compared with the standard new material casting photo template to determine whether there are defects on the surface of the new material castings, thereby improving the detection effect and quality of the appearance inspection device. The fork rotates on the semi-circular block and slides in the cylinder. The cylinder drives the axle disk to rotate, and the axle disk rotates in the carrier plate. The axle disk drives the first spring to rotate. The elastic force of the first spring slows down the rotation speed of the axle disk. The fork supports the semi-circular block, reducing the shaking when the camera body rotates. This prevents the camera from shaking when adjusting the camera lens position. As a result, the high-definition image of the surface of the new material casting is not clear, leading to poor comparison inspection effect of the appearance inspection device.

[0017] 2. The carrier plate drives the film plate to move up and down reciprocally, the film plate drives the first servo motor to move up and down reciprocally, and the output end of the first servo motor drives the camera body to move up and down reciprocally, adjusting the up and down position of the camera body lens; the carrier plate drives the sleeve to move down, and the rubber pad of the sleeve contacts the inside of the drive frame downward, limiting the distance the film plate moves down and preventing the bottom of the film plate from hitting the inside of the chassis slide.

[0018] 3. The square frame moves the curved frame plate downwards, bringing it into contact with the surface of the dual-axis frame. The curved frame plate presses against the triangular structure of the dual-axis frame, causing the dual-axis frame to slide to the right within the chassis. This movement causes the baffle to slide to the right, which in turn causes the foam pad to slide to the right. The camera lens descends to the left of the foam pad, which then covers the camera lens, preventing accidental damage. The notch on the dual-axis frame presses against the second spring to the left, causing the second spring to contract and store energy. The curved frame plate then leaves the surface of the dual-axis frame, releasing its elasticity. The dual-axis frame slides to the left within the chassis, causing the camera lens to rise and leave the baffle. The dual-axis frame quickly returns to its original position, preventing it from bumping into the lens during the return process.

[0019] 4. The strip plate drives the light shield to rotate, blocking backlight in front of the camera lens and improving the shooting effect of the camera. The light shield drives the double-axis plate to rotate, and under the elastic force of the arc-shaped spring, the rubber plate on the double-axis plate is tightly pressed against the surface of the camera lens, preventing the camera lens from loosening and falling off during displacement, which would cause poor performance of the appearance inspection device. The double ring frame drives the fill light to rotate, and the fill light follows the rotation of the camera lens, avoiding poor performance of the appearance inspection device in dim scenes.

[0022] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] Example 1, as Figures 1-10 As shown, a new material casting appearance inspection device for a die-casting production line includes: A vertical frame 1 is provided. A housing 2 is provided on the back of the vertical frame 1. A sliding groove is provided on the right side of the housing 2. A drive frame 3 is provided inside the housing 2. A threaded rod is rotatably installed inside the drive frame 3. A carrier plate 4 is slidably installed on the outer wall of the threaded rod of the drive frame 3. The inner wall of the carrier plate 4 meshes with the inner wall of the threaded groove of the threaded rod. Plate 5 is fixed to the right side of carrier plate 4. Servo motor 6 is fixedly installed on the top surface of plate 5. Camera body 7 is fixedly installed on the bottom surface of the output end of servo motor 6. Lens is fixedly installed on the right side of camera body 7. Sleeve 8, sleeve 8 is fixed to the left side of carrier plate 4; A semi-circular block 9 is fixed to the upper left side of the camera body 7. A fork 10 is hinged to the outer wall of the semi-circular block 9, and a cylinder 11 is slidably installed on the outer wall of the fork 10. A shaft disc 12 is mounted through and rotatably on the top surface of the carrier plate 4. The outer wall of the shaft disc 12 is fixedly connected to the inner wall of the cylinder 11. A spring 13 is provided between the top of the shaft disc 12 and the top surface of the carrier plate 4. The vertical frame 1 is located on the left side of the casting transport platform. A cabinet door is opened on the back of the machine box 2. A servo motor 2 is provided on the bottom surface of the drive frame 3. The output end of the servo motor 2 is fixedly connected to the bottom surface of the threaded rod. The carrier plate 4 is slidably mounted on the inner wall of the slide groove of the machine box 2. A rubber pad is provided on the bottom surface of the sleeve 8. The semi-circular block 9 is located below the plate 5. The fork 10 is located to the left of the semi-circular block 9. The vertical frame 1 is installed on the left side of the die-casting transport line. When the die-casting production line transports new material castings, the operator starts the second servo motor on the drive frame 3. The output end of the second servo motor begins to rotate in both directions, driving the threaded rod to rotate in both directions. The threaded rod rotates in both directions within the frame. Under the constraint of the slide groove in the housing 2, the carrier plate 4 slides up and down in the threaded groove of the threaded rod. The carrier plate 4 moves up and down in the slide groove in the housing 2, driving the plate 5 to move up and down. The plate 5 drives the first servo motor 6 to move up and down. The output end of the first servo motor 6 drives the camera body 7 to move up and down, adjusting the up and down position of the lens of the camera body 7. At the same time, the first servo motor 6 is started, and its output end rotates in both directions, driving the camera body 7 to move up and down. The main body 7 rotates back and forth. The camera body 7 can adjust the lens deflection angle of the camera body 7 according to different usage scenarios, so that the lens of the camera body 7 can follow the new material casting on the transport line to take pictures, ensuring that the camera body 7 captures high-definition images of the new material casting. The camera body 7 automatically sends the high-definition images of the new material casting to the computer terminal, compares the high-definition images of the new material casting with the standard new material casting photo template, and thus judges whether there are defects on the surface of the new material casting, improving the detection effect and quality of the appearance inspection device. While the carrier plate 4 moves downward, the carrier plate 4 drives the sleeve 8 to move downward. The rubber pad of the sleeve 8 contacts the inside of the drive frame 3 downward, limiting the downward movement distance of the plate 5 and preventing the bottom of the plate 5 from hitting the inside of the slide of the chassis 2. While the output of servo motor 6 drives the camera body 7 to rotate, the camera body 7 drives the semi-circular block 9 to rotate. Under the constraint of the carrier plate 4, the fork 10 rotates on the semi-circular block 9 and slides in the cylinder 11. The cylinder 11 drives the shaft disk 12 to rotate, and the shaft disk 12 rotates in the carrier plate 4. The shaft disk 12 drives the spring 13 to rotate, and the spring 13 twists and deforms. The elastic force of the spring 13 slows down the rotation speed of the shaft disk 12. Under the action of the elastic force of the spring 13, the fork 10 supports the semi-circular block 9, reducing the shaking when the camera body 7 rotates. This avoids the problem that when the appearance inspection device is inspecting new material castings, the camera shakes when the camera lens is adjusted, resulting in unclear high-definition images of the surface of the new material castings and poor comparison inspection effect of the appearance inspection device.

[0024] Example 2, as Figures 1-10 As shown, based on Embodiment 1, a storage device 14 is provided on the outer wall of the carrier plate 4, which is used to protect the lens of the camera body 7; a lens pressing device 15 is provided on the front and back of the camera body 7, which is used to fasten the lens of the camera body 7.

[0025] Storage device 14 includes: A rectangular frame 141 is fixed to the top surface of the carrier plate 4, and a frame arc plate 142 is fixed to the bottom surface of the rectangular frame 141. The dual-axis frame 143 is installed through and slidably on the lower left side of the inner wall of the chassis 2. The right side of the dual-axis frame 143 is embedded with a baffle 144, and a foam pad 145 is provided in the middle of the left side of the baffle 144. The square frame 141 is fitted on the outside of the carrier plate 4. The frame of the dual-axis frame 143 has a triangular structure, and the top surface of the dual-axis frame 143 is on the movement trajectory of the bottom surface of the frame arc plate 142. When the appearance inspection device is not in use, the threaded rod of the drive frame 3 continues to rotate forward. The carrier plate 4 drives the plate 5 to move downward, the plate 5 drives the servo motor 6 to move downward, and the output end of the servo motor 6 drives the camera body 7 to move downward. The carrier plate 4 drives the square frame 141 to move downward, and the square frame 141 drives the frame arc plate 142 to move downward. During the downward movement of the frame arc plate 142, the frame arc plate 142 and the surface of the dual-axis frame 143 come into contact. The frame arc plate 142 squeezes the triangular structure of the dual-axis frame 143, and the dual-axis frame 143 slides to the right in the housing 2. The dual-axis frame 143 drives the baffle 144 to slide to the right, and the baffle 144 drives the foam pad 145 to slide to the right. At this time, the lens of the camera body 7 descends to the left of the foam pad 145. The foam pad 145 on the baffle 144 covers the lens of the camera body 7, so that when the appearance inspection device is not in use, the foam pad 145 protects the lens of the camera body 7 and prevents the lens of the camera body 7 from being accidentally damaged.

[0026] A notch 146 is provided in the middle of the right side of the frame of the dual-axis frame 143. A spring 147 is fixed to the right side of the inner wall of the notch 146. A connecting plate 148 is fixed to the end of the spring 147 away from the notch 146. The connecting plate 148 is fixed to the lower left side of the inner wall of the chassis 2. While the frame arc plate 142 presses against the dual-axis frame 143, the notch 146 on the dual-axis frame 143 presses against the second spring 147 to the left. Under the constraint of the connecting plate 148, the second spring 147 contracts and stores energy. When the appearance inspection device is in use, the carrier plate 4 drives the square frame 141 to move upward, and the square frame 141 drives the frame arc plate 142 to move upward. The frame arc plate 142 leaves the surface of the dual-axis frame 143, and the second spring 147 releases its elastic force. The dual-axis frame 143 slides to the left in the housing 2, and the lens of the camera body 7 rises and leaves the baffle 144. This allows the second spring 147 to release its elastic force when the appearance inspection device is in use, so that the dual-axis frame 143 can quickly reset and the lens of the camera body 7 can start working. This avoids the dual-axis frame 143 hitting the lens when it resets during the use of the appearance inspection device.

[0027] The mirror pressing device 15 includes: Two strips 151 are fixed to the front and back of the camera body 7, and a light shield 152 is embedded in the right side of the two strips 151. A double-axis plate 153 is installed through and slidably on the top surface of the light-shielding plate 152. An arc-shaped spring piece 154 is provided between the top of the inner end of the double-axis plate 153 and the top surface of the light-shielding plate 152. Rubber plate 155 is fixed to the bottom surface of double-axis plate 153; light shield 152 is set to tilt upwards, and rubber plate 155 is set above the lens of camera body 7; While the servo motor 6 drives the camera body 7 to rotate, the camera body 7 drives the strip 151 to rotate, and the strip 151 drives the light shield 152 to rotate. This allows the light shield 152 to block the backlight in front of the camera body 7 lens, preventing the backlight from affecting the image captured by the camera body 7 and improving the shooting effect of the camera body 7. At the same time, the light shield 152 drives the dual-axis plate 153 to rotate, and the dual-axis plate 153 drives the arc-shaped spring 154 to rotate. Under the action of the elasticity, the rubber plate 155 on the dual-axis plate 153 is tightly pressed against the surface of the camera body 7 lens, preventing the camera body 7 lens from loosening during displacement. This avoids the problem of the camera body 7 lens loosening and falling off during displacement when the appearance inspection device is inspecting new material castings, which would cause poor performance of the appearance inspection device.

[0028] A double-ring frame 156 is provided on the lower part of the outer wall of the double-axis plate 153, and a supplementary light 157 is fixedly installed on the front of the double-ring frame 156. While the dual-axis plate 153 drives the arc-shaped spring 154 to rotate, the dual-axis plate 153 drives the dual-ring frame 156 to rotate, and the dual-ring frame 156 drives the fill light 157 to rotate. The fill light 157 follows the rotation of the camera body 7 lens and provides real-time fill light to the camera body 7 lens, so that the camera body 7 can still take clear photos of the new material casting in dim scenes, avoiding the problem of poor performance of the appearance inspection device in dim scenes.
