Description

Technical Field

[0001] The invention relates to the technical field of visual inspection, in particular to a machine vision intelligent inspection device for automobile parts production. Background Art

[0002] A machine vision intelligent detection device is a device that uses an optical imaging system (such as a camera) to obtain images of auto parts, and then processes and analyzes the images through a computer vision algorithm. It can detect multiple quality indicators such as dimensional accuracy, shape error, and surface defects of parts. During long-term use of the detection device, dust will adhere to the lens of its camera. When dust adheres to the surface of the camera lens, it will change the propagation path of light, which may cause the captured image of auto parts to appear blurred, with reduced contrast and uneven brightness. Therefore, the staff needs to clean the camera lens regularly. When cleaning the camera lens, the staff cannot accurately control the frequency of cleaning. If the cleaning is too frequent, the coating on the surface of the lens is easily scratched and worn, which will affect the optical performance of the lens and reduce the image quality. If the cleaning interval is too long, dust will accumulate too much on the lens surface, which will make the captured image of auto parts become more and more blurred. Blurred images will make it difficult to accurately identify defects, increasing the probability of misjudgment. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1 Reference Figure 1-Figure 10, which is the first embodiment of the present invention, and this embodiment provides a machine vision intelligent detection device for automobile parts production. The machine vision intelligent detection device for automobile parts production includes a detection component 100, including a mechanical arm 101, a mounting frame 102 is arranged on the mechanical arm 101, a shooting camera 103 is arranged in the mounting frame 102, a lens 104 is arranged on one side of the shooting camera 103, and a light source 105 is arranged at the bottom of the mounting frame 102.

[0033] The mounting frame 102 is used to install and fix the shooting camera 103, the light source 105 is used to increase the brightness of the accessories that need to be photographed, and the robotic arm 101 is used to drive the shooting camera 103 to move. Through the cooperation of the shooting camera 103 and the lens 104, the surface of the automotive accessories can be photographed, so as to detect various quality indicators of the accessories such as size accuracy, shape error, surface defects, etc. After inspecting a group of accessories, the robotic arm 101 will drive the shooting camera 103 and the lens 104 to move to one side and be in a standby state, so as to avoid accidental touching of the lens 104 during the replacement of the accessories that need to be inspected. When the accessories are replaced, the robotic arm 101 will drive the shooting camera 103 and the lens 104 to photograph the accessories again. This is a prior art, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0034] The cleaning component 200 is arranged on one side of the mounting frame 102, and includes a cleaning member 201. The cleaning member 201 includes a protective plate 201a, and the protective plate 201a is located on one side of the mounting frame 102. A fixed sleeve 201b is fixed on one side of the protective plate 201a, and a cleaning block 201c is arranged in the fixed sleeve 201b. A fixed column 201d is fixed on one side of the cleaning block 201c. A rotating sleeve 201e is rotatably connected to the fixed sleeve 201b, and a fixed shaft 201f is fixed in the rotating sleeve 201e. A spiral groove 201d-1 is provided on the fixed column 201d. A slider 201g is fixed on one side of the cleaning block 201c, and a sliding groove 201b-1 is provided in the fixed sleeve 201b. The slider 201g slides in the sliding groove 201b-1. An annular groove 201b-2 is provided in the fixed sleeve 201b, and the sliding groove 201b-1 is connected to the annular groove 201b-2.

[0035] A soft brush is fixed on one side of the cleaning block 201c, and there are multiple slide grooves 201b-1, which are evenly distributed in the fixed sleeve 201b in a ring shape.

[0036] When the robotic arm 101 drives the shooting camera 103 and the lens 104 to move to one side and is in standby mode, the protective plate 201a will move downward and rotate to the bottom of the lens 104, so as to cover the lens 104, thereby reducing the chance of dust falling on the surface of the lens 104 and reducing the possibility of image quality degradation due to dust accumulation. This helps to maintain clear imaging of the lens 104 for a period of time and reduce the number of times frequent cleaning is required due to dust problems.

[0037] When the protective plate 201a moves up and down multiple times and the lens 104 has been used for a period of time, when the protective plate 201a moves to the bottom of the lens 104 again, the rotating sleeve 201e will drive the fixed shaft 201f to slide in the spiral groove 201d-1. The cooperation of the two will drive the cleaning block 201c to move, so that the cleaning block 201c moves to a position where it can contact the lens 104. When the cleaning block 201c moves, it will drive the slider 201g to slide in the slide groove 201b-1. The cooperation of the two will prevent the cleaning block 201c from rotating and becoming unable to move.

[0038] When the brush of the cleaning block 201c contacts the lens 104, the slider 201g will enter the annular groove 201b-2, and the fixed shaft 201f will move to the end of the inner wall of the spiral groove 201d-1. At this time, the cleaning block 201c can no longer move. When the rotating sleeve 201e continues to rotate, it can drive the cleaning block 201c to rotate, so that the surface of the lens 104 can be cleaned by the cleaning block 201c, thereby preventing the dust attached to the surface of the lens 104 from affecting the use of the lens 104.

[0039] Example 2 Reference Figure 2-Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0040] Specifically, the cleaning component 200 also includes a positioning member 202, which includes a positioning column 202a, which is inserted into the protective plate 201a, and a positioning block 202b is fixed to the end of the positioning column 202a. A positioning rod 202c is fixed to one side of the mounting frame 102, and the positioning block 202b is movably connected to the outer side of the positioning rod 202c. A torsion spring 202d is fixed to the outer side of the positioning column 202a, and the other end of the torsion spring 202d is fixed to the inner side of the protective plate 201a.

[0041] There are two positioning blocks 202b and two positioning rods 202c, which are located on both sides of the protective plate 201a respectively. The bottom and top ends of the positioning rod 202c are L-shaped. The positioning column 202a is supported by the cooperation of the positioning block 202b and the positioning rod 202c, and the protective plate 201a is supported by the positioning column 202a. The torsion spring 202d is used to connect the positioning column 202a with the protective plate 201a so that the protective plate 201a can always be in a vertical state.

[0042] When the protective plate 201a is pushed downward, it will drive the positioning block 202b to move downward on the outside of the positioning rod 202c through the positioning column 202a. When the positioning block 202b moves to the bottom end of the positioning rod 202c, it will be restricted and unable to move downward. When the protective plate 201a continues to be pushed downward, it will rotate with the positioning column 202a as the center and rotate to the bottom of the lens 104, so as to shield and protect the lens 104.

[0043] When the protection plate 201a rotates, the torsion spring 202d is tightened. When the protection plate 201a is subjected to an upward pulling force, the torsion spring 202d can drive the protection plate 201a to rotate to a vertical state.

[0044] Specifically, the cleaning component 200 also includes a rotating member 203, which includes an installation box 203a, which is fixed to one side of the fixed sleeve 201b, a coil spring 203b is arranged in the installation box 203a, a rotating column 203c is inserted in the installation box 203a, the rotating column 203c is fixed to the inner ring of the coil spring 203b, a groove 203c-1 is provided on the rotating column 203c, a block 203d is provided in the groove 203c-1, a first spring 203e is fixed to the bottom of the block 203d, a slot 201e-1 is provided in the rotating sleeve 201e, and the block 203d is engaged with the slot 201e-1.

[0045] The rotating column 203c is rotatably connected to the fixed sleeve 201b through a bearing. One side of the clamping block 203d is inclined. There are multiple clamping grooves 201e-1, which are evenly distributed in a ring shape on the inner side of the rotating sleeve 201e.

[0046] When the protection plate 201a moves downward, the rotating column 203c drives the coil spring 203b to rotate and tighten the coil spring 203b.

[0047] The rotating column 203c is connected to the rotating sleeve 201e through the cooperation between the clamping block 203d and the clamping slot 201e-1, so that when the rotating column 203c is tightened with the coil spring 203b, the rotating column 203c will not drive the rotating sleeve 201e to rotate.

[0048] When the coil spring 203b releases its elastic force to drive the rotating column 203c to rotate in the opposite direction, the rotating column 203c can drive the rotating sleeve 201e to rotate through the cooperation between the clamping block 203d and the clamping slot 201e-1.

[0049] The first spring 203e applies a thrust to the clamping block 203d, so that the clamping block 203d and the clamping slot 201e-1 are more tightly engaged.

[0050] Specifically, the cleaning component 200 also includes a transmission member 204, which includes a first gear 204a. A support ring 204b is fixed to one side of the mounting box 203a, and the first gear 204a is rotatably connected to the outer side of the support ring 204b through a bearing. A support rod 204c is fixed to one side of the mounting frame 102, and a rack 204d is fixed to the end of the support rod 204c, and the rack 204d cooperates with the first gear 204a.

[0051] The support rod 204c is L-shaped, a ratchet is fixed on the outside of the rotating column 203c, a pawl is arranged on the inside of the first gear 204a, the pawl is meshed with the ratchet, and the first gear 204a is connected to the rotating column 203c through the cooperation of the pawl and the ratchet.

[0052] When the protection plate 201a moves downward and makes the first gear 204a mesh with the rack 204d, the first gear 204a rotates on one side of the rack 204d. At this time, the first gear 204a drives the rotating column 203c to rotate through the cooperation of the ratchet pawl.

[0053] The rack 204d is short, so when the first gear 204a is meshed with the rack 204d, the rotation angle thereof is small.

[0054] When the protection plate 201a moves upward and the first gear 204a rotates on one side of the rack 204d, the first gear 204a will not drive the rotating column 203c to rotate.

[0055] Specifically, the cleaning component 200 also includes a limit member 205, which includes a fixed frame 205a, which is fixed to one side of the installation box 203a. A limit rod 205b is arranged in the fixed frame 205a, and a limit groove 203c-2 is provided on the rotating column 203c. The bottom end of the limit rod 205b is engaged with the limit groove 203c-2, and a second spring 205c is fixed to the top of the limit rod 205b.

[0056] There are multiple limiting grooves 203c-2, which are evenly distributed in a ring shape on the outer side of the rotating column 203c, and one side of the limiting rod 205b is inclined.

[0057] The cooperation between the limit rod 205b and the limit groove 203c-2 is used to lock the rotation direction of the rotating column 203c, so that it can only rotate when the coil spring 203b is tightened, otherwise it cannot rotate, thereby preventing the elastic force of the coil spring 203b from being released at will. The second spring 205c is used to apply a thrust to the limit rod 205b. When the limit rod 205b is separated from the limit groove 203c-2, the second spring 205c can push the limit rod 205b to engage with the limit groove 203c-2 again.

[0058] Specifically, a positioning sleeve 205d is fixed to the top of the fixed frame 205a, a connecting column 205e is fixed to the top of the limiting rod 205b, a sealing block 205f is fixed to the top of the connecting column 205e, a baffle 205g is hinged to the top of the sealing block 205f through a hinge seat, a vent hole 205g-1 is provided on the baffle 205g, and a vent groove 205d-1 is provided on the positioning sleeve 205d, and the vent groove 205d-1 is close to the sealing block 205f.

[0059] The sealing block 205f fits tightly with the inner wall of the positioning sleeve 205d and is movably connected with the positioning sleeve 205d. As the rotating column 203c rotates, the limiting rod 205b will frequently move up and down, so that it can be engaged with different limiting grooves 203c-2.

[0060] When the limiting rod 205b moves upward, it will drive the connecting column 205e and the sealing block 205f to move in the positioning sleeve 205d. Since the upward movement stroke of the limiting rod 205b is short, the height of the sealing block 205f will not be higher than the air permeable groove 205d-1, so that the air flow can enter the positioning sleeve 205d through the air permeable groove 205d-1, so that the limiting rod 205b will not be hindered by negative pressure when moving downward.

[0061] When the limiting rod 205b moves upward too much and makes the height of the sealing block 205f higher than the air-permeable groove 205d-1, the sealing block 205f will generate airflow when moving and push the baffle 205g to open upward, so as not to hinder the upward movement of the sealing block 205f.

[0062] When the second spring 205c pushes the limiting rod 205b to move downward, and the limiting rod 205b drives the sealing block 205f to move downward, the baffle 205g will close downward under the action of gravity. When the sealing block 205f moves downward, a negative pressure will be generated above it, thereby limiting the downward movement of the sealing block 205f. At this time, air can only be introduced into the positioning sleeve 205d through the air vent 205g-1 with a smaller diameter, so that the sealing block 205f can move downward slowly, and the limiting rod 205b can be delayed to engage with the limiting groove 203c-2, so that the coil spring 203b has enough time to release the elastic force and drive the rotating column 203c to rotate.

[0063] Example 3 Reference Figure 1-Figure 12 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0064] Specifically, the cleaning component 200 also includes a pushing member 206, which includes a second gear 206a, the second gear 206a is fixed to one side of the first gear 204a, one side of the mounting box 203a is rotatably connected to a third gear 206b via a rotating shaft, the second gear 206a is meshed with the third gear 206b, a push rod 206c is fixed to one side of the third gear 206b, and a force rod 206d is fixed to one side of the limiting rod 205b.

[0065] The number of teeth on the second gear 206a is one tenth of that on the first gear 204a. When the first gear 204a rotates, it drives the second gear 206a to rotate. When the teeth on the second gear 206a mesh with the third gear 206b, the third gear 206b can be driven to rotate, so that the third gear 206b can drive the push rod 206c to approach the force rod 206d. When the push rod 206c pushes the force rod 206d to move upward, the force rod 206d can drive the limit rod 205b to move upward, thereby releasing the restriction on the rotating column 203c.

[0066] Since the second gear 206a has only one tenth of the teeth of the first gear 204a, when the first gear 204a drives the second gear 206a to rotate one circle, the second gear 206a will only drive the third gear 206b and the push rod 206c to rotate a small angle. Only when the first gear 204a drives the second gear 206a for multiple circles and dust is attached to the lens 104, will the push rod 206c push the force-bearing rod 206d to move upward.

[0067] When the coil spring 203b releases its elastic force to drive the rotating column 203c to rotate in the opposite direction, the rotating column 203c will simultaneously drive the first gear 204a and the second gear 206a to rotate in the opposite direction. At the same time, the second gear 206a drives the third gear 206b and the push rod 206c to rotate in the opposite direction. When the elastic force of the coil spring 203b is completely released, the push rod 206c will also return to its original position.

[0068] Specifically, one side of the cleaning block 201c is rotatably connected to a connecting ring 201c-1, one side of the connecting ring 201c-1 is fixed with a third spring 201c-2, and the other end of the third spring 201c-2 is fixed to the inner wall of the fixing sleeve 201b.

[0069] The third spring 201c-2 is connected and fixed to the cleaning block 201c through the connecting ring 201c-1. When the elastic force of the coil spring 203b is released, the connecting ring 201c-1 and the cleaning block 201c can be pulled back to their original positions by the third spring 201c-2. The elastic force of the coil spring 203b is greater than that of the third spring 201c-2.

[0070] Specifically, the cleaning component 200 also includes a driving member 207, which includes a cylinder 207a. The cylinder 207a is fixed to one side of the mounting frame 102. A rotating rod 207b is fixed to the top of the protective plate 201a. A connecting block 207c is fixed to the output end of the cylinder 207a. A positioning shaft 207d is fixed to the connecting block 207c. A positioning groove 207b-1 is provided on the rotating rod 207b, and the positioning shaft 207d slides in the positioning groove 207b-1.

[0071] The cylinder 207a is fixed to the mounting frame 102 through a fixing frame, and the connecting block 207c is connected to the rotating rod 207b through the cooperation between the positioning shaft 207d and the positioning groove 207b-1, and the rotating rod 207b is inclined.

[0072] When in use, when the robotic arm 101 drives the shooting camera 103 and the lens 104 to move to one side and is in standby mode, the cylinder 207a drives the connecting block 207c to move downward, and the connecting block 207c drives the rotating rod 207b and the protective plate 201a to move downward through the cooperation of the positioning shaft 207d and the positioning groove 207b-1. When the protective plate 201a cannot move downward any further, the positioning shaft 207d will slide in the positioning groove 207b-1, and the cooperation of the two drives the rotating rod 207b to rotate, so that the rotating rod 207b can drive the protective plate 201a to rotate and rotate to the bottom of the lens 104, so as to block the lens 104, thereby reducing the chance of dust falling on the surface of the lens 104 and reducing the possibility of image quality degradation due to dust accumulation. This helps to maintain clear imaging of the lens 104 for a period of time and reduces the number of frequent cleanings required due to dust problems.

[0073] When the protective plate 201a moves downward and makes the first gear 204a mesh with the rack 204d, the first gear 204a will rotate on one side of the rack 204d. At this time, the first gear 204a will drive the rotating column 203c to rotate through the cooperation of the ratchet pawl, and the rotating column 203c will drive the coil spring 203b to rotate and tighten the coil spring 203b.

[0074] At the same time, when the first gear 204a rotates, it will drive the second gear 206a to rotate. When the teeth on the second gear 206a mesh with the third gear 206b, the third gear 206b can be driven to rotate, so that the third gear 206b can drive the push rod 206c to approach the force-bearing rod 206d. When the protective plate 201a moves up and down many times and the first gear 204a drives the second gear 206a for many circles, dust has been attached to the lens 104 at this time. The push rod 206c will push the force-bearing rod 206d to move upward, and the force-bearing rod 206d can drive the limit rod 205b to move upward, thereby releasing the restriction on the rotating column 203c.

[0075] At this time, the coil spring 203b releases its elastic force to drive the rotating column 203c to rotate in the opposite direction. The rotating column 203c drives the rotating sleeve 201e to rotate through the cooperation between the card block 203d and the card slot 201e-1. The rotating sleeve 201e will drive the fixed shaft 201f to slide in the spiral groove 201d-1. The cooperation between the two drives the cleaning block 201c to move, so that the cleaning block 201c moves to a position where it can contact the lens 104. When the cleaning block 201c moves, it will drive the slider 201g to slide in the slide groove 201b-1. The cooperation between the two prevents the cleaning block 201c from rotating and becoming unable to move.

[0076] When the brush of the cleaning block 201c contacts the lens 104, the slider 201g will enter the annular groove 201b-2, and the fixed shaft 201f will move to the end of the inner wall of the spiral groove 201d-1. At this time, the cleaning block 201c can no longer move. When the rotating sleeve 201e continues to rotate, it can drive the cleaning block 201c to rotate, so that the surface of the lens 104 can be cleaned by the cleaning block 201c, thereby preventing the dust attached to the surface of the lens 104 from affecting the use of the lens 104.
