[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0021] Example 1
[0022] Reference Figure 1 and Figure 2 As shown in the figure, this application discloses a rapid photographic inspection device for nuts, including: a frame 1; a placement platform 2, rotatably mounted on the frame 1 for placing products; an image acquisition component 3, used to photograph the product and acquire actual image information; a telescopic component 4, the main body of which is hinged to the frame 1, and the piston rod of which is hinged to the lower side of the placement platform 2; wherein, the piston rod of the telescopic component 4 retracts, which can tilt the placement platform 2, thereby causing the product to slide off the placement platform 2; a control terminal, electrically connected to the image acquisition component 3 and the telescopic component 4; and a first belt conveyor 51, which is located below the placement platform 2 and on the product's falling path.
[0023] In practical use, the product to be tested is first placed on the placement platform 2. The image acquisition component 3 takes a picture of the surface of the product to be tested and obtains the actual image information of the surface of the product to be tested. The image information is then transmitted to the control terminal, which compares the actual image information with the theoretical image information stored in the control terminal.
[0024] If the actual image information matches the theoretical image information, the control terminal transmits an electrical signal to the telescopic component 4. The piston rod of the telescopic component 4 performs one extension stroke, tilting the storage platform 2. The product slides from the storage platform 2 onto the first belt conveyor 51, which then transports the product to the next process.
[0025] If the actual image does not match the theoretical image, the defective product will be removed manually.
[0026] By using this invention, the nuts on the product to be inspected can be quickly and accurately tested to determine whether the welding of the nuts meets the production requirements; it can effectively reduce manual labor and improve the inspection efficiency of the nut welding work of the product.
[0027] It is worth mentioning that the image acquisition component 3 can be a CCD industrial camera.
[0028] Preferably, a box can be provided at one end of the first belt conveyor 51 to receive the products.
[0029] It is understandable that the control terminal uses a PC as a processing platform, acquires images through a CCD industrial camera, performs image processing on the PC processing platform, and outputs the analysis results to output devices such as displays or control mechanisms; the specific process of how to perform machine vision analysis based on the acquired images is well-known technology in the field, and will not be elaborated here.
[0030] It is worth mentioning that the telescopic component 4 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.
[0031] Preferably, the device further includes: a material unloading window, which is opened on the frame 1; a first mounting shaft 61, which is mounted on the frame 1, and a placement platform 2 is hinged on the first mounting shaft 61; wherein, the piston rod of the telescopic component 4 extends, which can place the placement platform 2 horizontally in the material unloading window.
[0032] In the initial state, the piston rod of the telescopic component 4 is in the extended state, and the piston rod of the telescopic component 4 supports the placement platform 2 to keep it in a horizontal state for product placement.
[0033] Specifically, the device also includes an arc-shaped baffle 71, which is mounted on the frame 1 and located on the side of the discharge window away from the first mounting shaft 61, for guiding the product to fall.
[0034] Specifically, the device also includes an inclined baffle 72, installed on one side of the first belt conveyor 51, for guiding the product to fall.
[0035] In this embodiment, the product is guided to fall by setting the arc-shaped baffle 71 and the inclined baffle 72, ensuring that the product falls on the first belt conveyor 51 and preventing the product from falling to the ground and being damaged.
[0036] Example 2
[0037] Reference Figure 3 and Figure 4As shown, in this embodiment, the device further includes: a second belt conveyor 52, installed parallel to one side of the first belt conveyor 51; a movable platform 8, movably installed on the frame 1, vertically positioned above the first belt conveyor 51 and the second belt conveyor 52, and below the placement platform 2; a drive assembly for driving the movable platform 8 to perform linear reciprocating motion along a straight line, thereby placing the movable platform 8 above the first belt conveyor 51 or the second belt conveyor 52; a first baffle 81, rotatably mounted on the frame 1, positioned above the placement platform, for pushing the product onto the first belt conveyor 51; a rotating component 83 for driving the first baffle 81 to rotate, allowing the product to pass through; and a second baffle 82, rotatably mounted on the frame 1, positioned above the placement platform, for pushing the product onto the second belt conveyor 52.
[0038] In the initial state, the mobile platform 8 is above the first belt conveyor 51; after the test is completed, the piston rod of the telescopic component 4 extends and retracts, the product slides onto the tilted platform 2 and the drive component is activated, causing the mobile platform 8 to carry the product and move along the width direction of the first belt conveyor 51 and the second belt conveyor 52.
[0039] If the actual image information of the product matches the theoretical image information, the first baffle 81 is in a vertically installed state. When the mobile platform 8 passes under the first baffle 81, the first baffle 81 can push the product that meets the production requirements on the mobile platform 8 onto the first belt conveyor 51.
[0040] If the actual image information of the product matches the theoretical image information, the first baffle 81 is in a vertically installed state. When the mobile platform 8 passes under the first baffle 81, the first baffle 81 can push the product that meets the production requirements on the mobile platform 8 onto the first belt conveyor 51.
[0041] If the actual image information of the product does not match the theoretical image information, the control terminal transmits an electrical signal to the rotating component 83. The rotating component 83 drives the first baffle 81 to rotate 90°. The first baffle 81 is in a horizontal installation state, and the mobile platform 8 can carry the product that does not meet the production requirements through the bottom of the first baffle 81. When the mobile platform 8 passes under the second baffle 82, the second baffle 82 can push the product that does not meet the production requirements on the mobile platform 8 onto the second belt conveyor 52.
[0042] In this utility model, by setting up a mobile platform 8, the product can fall in two stages, which can effectively reduce the impact between the product and the belt conveyor and play a certain role in protecting the product. In addition, it can also classify and transport products with different processing quality, sending products that meet the production requirements to the first belt conveyor 51 and sending products that do not meet the production requirements to the second conveyor, eliminating the need for manual handling of products that do not meet the production requirements.
[0043] In this embodiment, the device further includes two limiting plates 84, which are fixedly mounted on the frame 1 and located on both sides of the mobile platform 8; by setting the limiting plates 84 on both sides of the mobile platform 8, the product is prevented from falling off the mobile platform 8.
[0044] Specifically, the drive assembly includes: a lead screw 85, which is rotatably mounted on the frame 1 and is connected to the moving platform 8 by a threaded transmission; a guide rod 86, which is fixedly mounted on the frame 1 and slidably mounted on the moving platform 8; and a drive motor 87, which drives the lead screw to rotate.
[0045] Specifically, the output shaft of the drive motor 87 is connected to the lead screw 85 via a coupling. Rotation of the output shaft of the drive motor 87 drives the lead screw 85 to rotate. Under the guidance of the guide rod 86, the moving platform 8 moves along the axial direction of the lead screw 85. Of course, by changing the direction of rotation of the output shaft of the drive motor 87, the moving platform 8 can be reset.
[0046] Specifically, the device also includes: a second mounting shaft 62, which is rotatably mounted on a limiting plate 84, and a first baffle 81 is fixedly mounted on the second mounting shaft 62.
[0047] It is worth mentioning that the lead screw 85 can be rotatably mounted on the frame 1 via bearings, and the second mounting shaft 62 can also be rotatably mounted on the limit plate 84 via bearings.
[0048] It is worth mentioning that the rotating component 83 can be a motor, and the second mounting shaft 62 is connected to the output shaft of the motor via a coupling.
