Description

Technical Field

[0001] The present invention relates to the technical field of silicone product detection, and in particular to a silicone product appearance detection device. Background Art

[0002] Silicone products that require visual inspection are widely distributed in industrial, medical, consumer and other fields. Visual inspection technology uses high-precision image analysis and automated algorithms to efficiently screen surface defects (such as bubbles, cracks, burrs) and dimensional accuracy of silicone products.

[0003] In the prior art, a visual inspection device for the appearance of silicone products generally sets a camera facing the silicone products on a conveyor line of silicone products. When the silicone products pass by the camera, the camera takes a picture of the silicone products to achieve appearance inspection of the silicone products.

[0004] Regarding the above-mentioned related technologies, the existing technology generally installs a camera facing the conveyor line above the conveyor line. When the silicone product moves past the camera, the camera takes a bird's-eye view of the silicone product for visual appearance inspection. However, the sides of some silicone products also need to be visually inspected. Installing cameras on all sides of the conveyor line is obviously too expensive. In summary, the existing silicone product appearance inspection device is not easy to fully inspect the surface of silicone products.

[0005] For this purpose, a device for detecting the appearance of silicone products is needed. Summary of the Invention

[0006] The present invention provides a silicone product appearance inspection device, which solves the problem in the prior art that existing silicone product appearance inspection devices are difficult to fully inspect the surface of silicone products.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0012] Preferably, a fill light protruding from the surface of the second camera is fixedly connected to the bottom end of the second camera, and light-emitting panels are fixedly installed on both inner walls of the chassis.

[0013] Preferably, the chassis is fixedly connected to mounting arms on both sides of the end where the silicone products enter, the mounting arms are fixedly connected to a vertical fixing column at the end away from the chassis, the top of the fixing column is rotatably connected to a guide plate for guiding on the surface of the conveyor belt, and the guide plate is rotatably connected to an adjusting rod at the end away from the fixing column.

[0014] Preferably, the mounting arm is provided with a slide groove along the length direction, a vertical sliding column is slidably connected in the slide groove, the adjustment rod is slidably connected to the top of the sliding column, and the top of the sliding column is also provided with a limiting structure for limiting the sliding of the adjustment rod.

[0015] Preferably, the chassis is fixedly installed with fixing plates above both ends of the silicone product, a plurality of shading plates are slidably connected in the vertical direction inside the fixing plates, and a vertical second telescopic column is fixedly installed on the outer surface of the fixing plates.

[0016] Preferably, the second telescopic column includes a fixed part fixedly connected to the fixed plate, and a telescopic part slidably connected to the fixed part. The bottom end of the telescopic part of the second telescopic column is fixedly connected to the bottom end of the light shielding plate. The light shielding plate can contact the conveyor belt when it moves downward, and will not interfere with the silicone products entering and exiting the chassis when it moves upward. The second camera can be lowered to the middle or upper part of the silicone product. The second camera can always move toward and around the silicone product during the transportation of the silicone product along the conveyor belt.

[0017] Preferably, the bottom end of the telescopic part of the first telescopic column is fixedly connected to the lifting frame, and the bottom end of the fixed part is connected to the mounting plate, the tail end of the second camera is slidably connected to the moving block along the length direction, the top end of the moving block is rotatably connected to the sliding rod, the sliding rod passes upward through the lifting frame and is slidably connected to the mounting plate, and a limiting mechanism is installed on the mounting plate to limit the sliding of the sliding rod relative to the mounting plate, and the lifting frame is fixedly connected to a limiting rod below the head end of the second camera, and when the second camera is in a horizontal state, the distance between the top surface of the limiting rod and the second camera is equal to the distance between the top surface of the second camera and the top surface of the inner wall of the lifting frame.

[0018] The present invention proposes a device for inspecting the appearance of silicone products. Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a slide rail in a box through which a conveyor belt can pass, and installs a camera at the end of a rotating arm below the slide rail. When the silicone product moves to the bottom of the first camera, the slider keeps moving in the same direction and speed as the silicone product in the slide rail. At the same time, the rotating arm rotates after the first telescopic column adjusts the telescopic amount, allowing the second camera to surround the silicone product for shooting, effectively increasing the range of visual inspection of the silicone product and more fully realizing the visual inspection of the silicone product.

[0020] 2. The present invention controls the extension and contraction of the first telescopic column. After the second camera completes the surround shooting of the silicone product, the slider slides in the opposite direction. At the same time, the first telescopic column contracts, so that the fill light below the second camera can push the silicone product onto the conveyor belt, exposing the bottom surface of the silicone product. Then the slider resumes movement in the same direction as the conveyor belt, so that the second camera moves away from the silicone product and shoots the bottom surface of the silicone product, further improving the visual inspection range of the silicone product.

[0021] 3. The present invention provides an adjustable guide mechanism at the silicone product inlet end of the chassis, so that the silicone product moving on the conveyor belt moves to the middle position of the conveyor belt under the guidance of the guide mechanism, so that the top of the center position of the silicone product can correspond to the first camera. During the rotation of the rotating arm, the second camera can better shoot the silicone product, and at the same time avoid the second camera from colliding with the silicone product when shooting around the silicone product.

[0022] 4. The present invention arranges light-emitting panels on both sides of the chassis. When the second camera faces the two sides of the silicone product, the light-emitting panels emit light to make the outline of the silicone product appear more clearly. Under the action of the fill light of the second camera, the surface of the silicone product can be photographed more clearly, effectively improving the accuracy of visual inspection of silicone products.

[0023] 5. The present invention sets a vertically lifting shading structure at both ends of the chassis. When the silicone product enters the interior of the chassis, the shading structure descends to maintain a darker environment inside the chassis, effectively avoiding the influence of light in the external environment on the visual inspection results, and further improving the accuracy of visual inspection of silicone products.

[0024] 6. The present invention rotatably installs a second camera at the bottom end of the first telescopic column, utilizes a sliding rod slidably connected to the bottom end of the first telescopic column to connect with the tail end of the second camera, and realizes the pitch angle adjustment of the second camera by controlling the sliding rod and the extension of the first telescopic column. For some silicone products with complex structures, multi-angle shooting can be adopted, further improving the visual inspection effect of silicone products. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-11 The present invention provides a technical solution: a silicone product appearance inspection device, including a chassis 1, a slide rail 2 is installed at the top of the chassis 1, and a slider 3 is slidably connected to the slide rail 2 along the length direction. Specifically, the principle of the slider 3 sliding in the slide rail 2 is the principle of a linear guide rail, which will not be described here. One end of a rotating arm 5 is connected to the bottom of the slider 3 through a steering motor 4. Specifically, in this embodiment, the steering motor 4 is an axial flux motor. The other end of the rotating arm 5 is fixedly connected to a first telescopic column 6. The bottom end of the first telescopic column 6 is installed with a second camera 8 horizontally facing the rotating axis of the rotating arm 5. Specifically, in this application, the first telescopic column 6 and the second telescopic column 20 are both electric push rods.

[0039] It also includes a first camera 7, which is installed at the bottom end of the rotating arm 5 at the rotating shaft position. A conveyor belt 21 passes through the chassis 1. The chassis 1 is installed with a guide mechanism for guiding the silicone products to the center of the conveyor belt 21 at the entry end of the silicone products. The first camera 7 moving along the slide rail 2 is always located at the center position of the conveyor belt 21 in the width direction. Specifically, in this embodiment, the first camera 7 and the second camera 8 are both industrial cameras used for visual inspection.

[0040] In the above embodiment, please refer to Figure 2-3 、 Figure 7-8The bottom end of the slider 3 is fixedly connected to the housing of the steering motor 4, and the bottom end of the rotating shaft of the steering motor 4 extends downward and is fixedly connected to a rotating arm 5. The bottom surface of the rotating arm 5 is coaxially connected to the steering motor 4 with a first camera 7 facing downward. The steering motor 4 is used to adjust the rotation angle of the rotating arm 5. Specifically, when performing a surround visual inspection of silicone products, the rotating arm 5 rotates slowly under the drive of the steering motor 4, and the second camera 8 continuously records and detects defects in the silicone products. When the second camera 8 rotates one circle, visual inspection of the sides of the silicone products can be achieved.

[0041] Specifically, the first telescopic column 6 includes a fixed part and a telescopic part. The fixed part of the first telescopic column 6 is fixedly connected to the rotating arm 5 and is orthogonal to the rotating arm 5. The bottom end of the telescopic part of the first telescopic column 6 is connected to the top of the second camera 8. By controlling the extension and contraction of the first telescopic column 6, the second camera 8 can be aimed at silicone products of different heights. Specifically, in this embodiment, when performing visual inspection of silicone products, the extension and contraction amount of the first telescopic column 6 is controlled, so that the second camera 8 is directed to the middle position of the silicone product to obtain a more accurate detection viewing angle, thereby avoiding missed shots or excessive visual distortion due to too high or too low viewing angles.

[0042] Second embodiment:

[0043] A device for inspecting the appearance of silicone products, please refer to Figure 1-8 Based on the first embodiment, the difference from the first embodiment is that the length of the rotating arm 5 is less than half the width of the chassis 1, and a counterweight block 501 is connected to the end away from the first telescopic column 6. The counterweight block 501 is used to improve the stability of the rotating arm 5 during the rotation process, and the rotating arm 5 is prevented from being too long and interfering with the inner wall of the chassis 1 during the rotation process.

[0044] In the above embodiment, please refer to Figure 2-3 、 Figure 7-8 The bottom end of the second camera 8 is fixedly connected to a fill light 9 protruding from the surface of the second camera 8. Specifically, in the process of pushing down the silicone product, the shell of the fill light 9 contacts the silicone product to push it down, effectively preventing the silicone product from contacting the glass lens of the second camera 8 and causing it to be contaminated with dust or dirt.

[0045] Furthermore, both inner walls of the chassis 1 are fixedly mounted with light panels 10, which are specifically LED light-homogenizing panels that can clearly display the outline of the silicone product, further improving the accuracy of visual inspection of the silicone product. The fill light 9 and the light panel 10 both help the second camera 8 and the first camera 7 to more clearly photograph the silicone product.

[0046] In the above embodiment, please refer to Figure 7-8The second camera 8 can be lowered to the middle or upper part of the silicone product. Specifically, when the second camera 8 is lowered to the middle position of the silicone product, it is to clearly shoot the silicone product, and when it is moved to the upper part of the silicone product, it is to better push down the silicone product to avoid the silicone product and the conveyor belt 21 from sliding relative to each other and being unable to be pushed down during the process of pushing down the silicone product. The second camera 8 can always move toward and around the silicone product during the transportation of the silicone product along the conveyor belt 21, so that the second camera 8 can cooperate with the relative movement of the conveyor belt 21 to push down the silicone product after completing shooting all around the silicone product, so as to shoot the bottom surface of the silicone product.

[0047] The third embodiment:

[0048] A device for inspecting the appearance of silicone products, please refer to Figure 1-8 On the basis of the second embodiment, the difference from the second embodiment is that the chassis 1 is fixedly connected to mounting arms 11 on both sides of the end where the silicone products enter, and the end of the mounting arm 11 away from the chassis 1 is fixedly connected to a vertical fixing column 14, and the top of the fixing column 14 is rotatably connected to a guide plate 15 for guiding on the surface of the conveyor belt 21, and the end of the guide plate 15 away from the fixing column 14 is rotatably connected to an adjusting rod 16, which pushes the guide plate 15 to rotate around the fixing column 14 through the adjusting rod 16, so that the silicone products can be guided by the guide plate 15 when moving on the conveyor belt 21. Specifically, in order to move the silicone products to the center position of the width direction of the conveyor belt 21, the guide plates 15 on both sides of the conveyor belt 21 are symmetrically arranged.

[0049] Furthermore, the mounting arm 11 is provided with a slide groove 12 along the length direction, and a vertical sliding column 13 is slidably connected in the slide groove 12. In this embodiment, the sliding column 13 can slide in the slide groove 12 to adjust its position and position. The specific positioning means are recorded in detail in the prior art, and this application will not go into details here. The adjusting rod 16 is slidably connected to the top end of the sliding column 13, and the top end of the sliding column 13 is also provided with a limiting structure for limiting the sliding of the adjusting rod 16. Specifically, in this embodiment, the top end of the sliding column 13 is rotatably connected to a fixing knob 17. When the fixing knob 17 is tightened, friction can be used to limit the relative sliding between the sliding column 13 and the adjusting rod 16. By adjusting the sliding position of the sliding column 13 in the slide groove 12, the flexibility of the adjusting rod 16 in controlling the rotation of the guide plate 15 is further improved.

[0050] In the above embodiment, please refer to Figure 4-6The chassis 1 is fixedly installed with a fixing plate 18 above both ends of the entry and exit of the silicone product. A plurality of light shielding plates 19 are connected to the fixing plate 18 in a vertical sliding manner. A vertical second telescopic column 20 is fixedly installed on the outer surface of the fixing plate 18. The light shielding plate 19 is lowered after the silicone product enters the chassis 1, effectively preventing external light from affecting the accuracy of the detection results.

[0051] Specifically, the second telescopic column 20 includes a fixed part fixedly connected to the fixed plate 18, and a telescopic part slidably connected to the fixed part. The bottom end of the telescopic part of the second telescopic column 20 is fixedly connected to the bottom end of the light shielding plate 19. The light shielding plate 19 can contact the conveyor belt 21 when it moves downward, and will not interfere with the silicone products entering and exiting the chassis 1 when it moves upward, thereby avoiding the existence of light-transmitting gaps in the chassis 1 after the light shielding plate 19 is lowered.

[0052] Fourth embodiment:

[0053] A device for inspecting the appearance of silicone products, please refer to Figure 1-11 On the basis of the second embodiment, the difference from the second embodiment is that the bottom end of the telescopic part of the first telescopic column 6 is fixedly connected to the lifting frame 22, and the bottom end of the fixed part is connected to the mounting plate 601. The tail end of the second camera 8 is slidably connected to the moving block 24 along the length direction. The top end of the moving block 24 is rotatably connected to the sliding rod 25. The sliding rod 25 passes upward through the lifting frame 22 and is slidably connected to the mounting plate 601. Specifically, a limiting mechanism for limiting the sliding of the sliding rod 25 relative to the mounting plate 601 is installed on the mounting plate 601. Specifically, the limiting mechanism is an electromagnetic push block 26 installed on the mounting plate 601. The electromagnetic push block 26 includes a fixed part fixedly connected to the mounting plate 601, and a telescopic part slidably connected to the inside of the fixed part. The end of the telescopic part of the electromagnetic push block 26 is fixedly connected to a friction block for rubbing against the outer wall of the sliding rod 25. When the electromagnetic push block 26 is not energized, the friction block does not contact the outer wall of the sliding rod 25. Otherwise, it contacts the outer wall of the sliding rod 25.

[0054] Furthermore, the lifting frame 22 is fixedly connected to a limit rod 23 below the head end of the second camera 8. When the second camera 8 is in a horizontal state, the distance between the top surface of the limit rod 23 and the second camera 8 is equal to the distance between the top surface of the second camera 8 and the top surface of the inner wall of the lifting frame 22, ensuring that the second camera 8 has the same pitch angle. When performing visual inspection on silicone products with complex configurations, the pitch angle of the second camera 8 can be adjusted during its descent to better perform visual inspection on the silicone products.

[0055] Specifically, when the telescopic part of the electromagnetic push block 26 is extended, the friction block of the telescopic part of the electromagnetic push block 26 contacts the side wall of the sliding rod 25. The friction between the electromagnetic push block 26 and the sliding rod 25 is used to temporarily prevent relative sliding between the sliding rod 25 and the electromagnetic push block 26. At this time, the telescopic part of the first telescopic column 6 is extended, and the moving block 24 will slide toward the tail end of the second camera 8. At the same time, the second camera 8 tilts downward until the second camera 8 is blocked by the limit rod 23. At this time, the second camera 8 remains in a downward tilted state. If the first telescopic column 6 continues to extend, since the second camera 8 has been retracted and limited, the moving block 24 cannot continue to slide toward the tail end of the second camera 8. Therefore, the sliding rod 25 and the electromagnetic push block 26 will slide relative to each other as the first telescopic column 6 extends.

[0056] Furthermore, the center of gravity of the second camera 8 is close to its own tail end. When the electromagnetic push block 26 is not in contact with the sliding rod 25, the second camera 8 is at an upward shooting angle due to its own gravity. At this time, no matter how the first telescopic column 6 is extended or retracted, the top of the second camera 8 always contacts the top surface of the inner wall of the lifting frame 22, maintaining the upward shooting angle. When it is necessary to restore the second camera 8 to a horizontal state, the electromagnetic push block 26 is contacted with the sliding rod 25, and the first telescopic column 6 is slowly extended. When the built-in horizontal sensor of the second camera 8 senses that the second camera 8 is in a horizontal state, the first telescopic column 6 stops extending or retracting.

[0057] Working principle: The silicone product is placed on the conveyor belt 21 and moves along the conveying direction of the conveyor belt 21. When the silicone product collides with the guide plate 15, the silicone product itself is still pushed by the conveyor belt, and is guided by the guide plate 15 to move to the position between the two guide plates 15 and pass through the two guide plates 15 from this position. At this time, the silicone product is guided by the guide plate 15 to move to the center position in the width direction of the conveyor belt 21;

[0058] When the first camera 7 facing downward captures a silicone product, it can visually inspect the top surface of the silicone product. The first telescopic column 6 extends, causing the second camera 8 to descend to the middle of the silicone product. Simultaneously, the slider 3 in the slide rail 2 moves synchronously and in the same direction as the conveyor belt 21. The steering motor 4 operates to cause the rotating arm 5 to rotate slowly and uniformly. During the rotation of the rotating arm 5, the second camera 8 always faces the silicone product, enabling multi-angle visual inspection of the silicone product's four sides after completing a circle.

[0059] When the rotating arm 5 rotates one circle, the slider 3 changes its movement direction so that the front end of the second camera 8 and the fill light 9 move toward the silicone product. At the same time, the first telescopic column 6 contracts a certain distance, so that the second camera 8 is directed to the upper end of the silicone product. As the fill light 9 and the silicone product move relative to each other, the fill light 9 contacts the top of the silicone product and pushes it down. Then the slider 3 slides quickly in the same direction as the conveying direction of the conveyor belt 21, and the sliding speed is faster than the conveying speed of the conveyor belt 21. Before the slider 3 slides to the end of the stroke, the second camera 8 can perform a final visual inspection of the bottom surface of the fallen silicone product. Multi-angle visual inspection of silicone products can be fully realized without installing a large number of cameras.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

A limiting mechanism for limiting the sliding of the sliding rod (25) relative to the mounting plate (601) is installed on the mounting plate (601). The lifting frame (22) is fixedly connected to a limiting rod (23) below the head end of the second camera (8). When the second camera (8) is in a horizontal state, the distance between the top surface of the limiting rod (23) and the second camera (8) is equal to the distance between the top surface of the second camera (8) and the top surface of the inner wall of the lifting frame (22).
