Description

[0002] In mechanical automation production, automatic inspection equipment is an indispensable and important component, and visual inspection is a more common inspection equipment among automatic inspection equipment. It is mainly used for inspections of angles, appearance, size, defects, scratches, burrs, dirt, etc.

[0003] Existing production lines generate dust when running at a high speed or during product production, which can easily attach to the camera lens. Small areas of dust stains will affect imaging, not only affecting the amount of light passing through, but also affecting clarity. They will be mistaken for defects or stains by the recognition system, and qualified products will be mistakenly judged as unqualified. Therefore, operators are required to wipe the lens of the visual inspection equipment at regular intervals. This method requires the production line to be stopped, which affects production and requires high labor intensity. It will also cause lens wear during long-term repeated wiping, thereby affecting visual imaging effects.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1-11The angle detection device based on machine vision shown in the figure includes a detection device body 1, a film applying mechanism 2 and a film feeding mechanism 3. The detection device body 1 includes a detection camera 11, a mounting frame 12 and a dust-proof glass cover 13. The detection camera 11 is fixedly mounted on the mounting frame 12. The dust-proof glass cover 13 is sleeved on the outside of the detection end of the detection camera 11. The dust-proof glass cover 13 is fixedly mounted on the mounting frame 12. The film applying mechanism 2 includes a first pushing component 21, a film peeling component 22, a cleaning component 23 and a pasting component 24. The first pushing component 21 is mounted on the mounting frame 12. The film peeling component 22 is mounted on the output end of the first pushing component 21. The cleaning component 23 and the pasting component 24 are both mounted on the mounting frame 12 and are located beside the dust-proof glass cover 13. The film feeding mechanism 3 includes a film feeding component 31 and an automatic residual detection component 32. The film feeding component 31 is fixedly mounted on the mounting frame 12 and is located on both sides of the dust-proof glass cover 13. The automatic residual detection component 32 is mounted on the film feeding component 31.

[0033] The present invention can realize the film application operation on the dust-proof glass cover 13 through the film application mechanism 2. The dust-proof glass cover 13 can protect the lens of the detection camera 11 to prevent scratches or dust from falling. Dust will fall on the dust-proof glass cover 13. The dust-proof film applied on the surface of the dust-proof glass cover 13 can prevent the dust-proof glass cover 13 from being contaminated by dust. When the dust-proof film applied on the dust-proof glass cover 13 is dirty, the film loading component 31 can automatically realize the automatic loading process of a new dust-proof film. The film application mechanism 2 can realize the re-application function. The first pushing component 21 drives the film peeling component 22 to work, and the dust film originally applied on the dust-proof glass cover 13 is removed. The dust-proof film on the dust-proof glass cover 13 is removed, and the surface of the dust-proof glass cover 13 will not be touched during the removal process to prevent scratches on the surface of the dust-proof glass cover 13. After the film removal operation is completed, the film-sticking position of the dust-proof glass cover 13 is cleaned by the cleaning component 23, and its surface is scrubbed with alcohol to facilitate the subsequent application of the dust-proof film and ensure that there is no dust residue at the film-sticking position. The dust-proof film can be tightly attached to the surface of the dust-proof glass cover 13 through the application component 24. The automatic remaining amount detection component 32 is used to detect the remaining amount of the dust-proof film in the film feeding component 31, and an alarm is sounded when it is about to run out, reminding the staff to change the material.

[0034] The present invention can greatly increase the continuous use time of the detection camera 11. Through the dust-proof glass cover 13 and the dust-proof film applied to the surface of the dust-proof glass cover 13, the clarity and accuracy of visual detection are maintained while working continuously, and dust and other substances are prevented from affecting the visual detection result of the detection camera 11. The film applying mechanism 2 can automatically perform operations such as film peeling, cleaning, and applying. The film feeding mechanism 3 can automatically perform film replacement operations without the need for operators to wipe or manually replace dust-proof components, so that the equipment can increase the continuous working time, can adapt to relatively harsh working environments, and avoid the visual detection effect of the detection camera 11 being affected by dust in the working environment. It has a wide range of applications and does not require operators to frequently enter dusty working areas to perform operations such as wiping and replacing, thereby improving work safety.

[0035] The first pushing assembly 21 includes a first fixed frame 211, a first sliding frame 212, a first sliding rod 213, a first spring 214 and a first linear driver 215. The first fixed frame 211 is fixedly installed on the mounting frame 12, the first sliding frame 212 is slidably arranged on the first fixed frame 211, the first sliding rod 213 is fixedly installed on the first sliding frame 212, the first sliding rod 213 is slidably connected to the first fixed frame 211, the first spring 214 is sleeved on the first sliding rod 213, the two ends of the first spring 214 are respectively fixedly connected to the first fixed frame 211 and the first sliding frame 212, the first linear driver 215 is fixedly installed on the first fixed frame 211, and the first linear driver 215 is transmission-connected to the first sliding frame 212.

[0036] When the first pushing component 21 is working, the first fixed frame 211 is used to install the first pushing component 21 on the mounting frame 12, and the first linear drive 215 drives the first sliding frame 212 connected thereto to slide in the direction close to the dust-proof film. When the first sliding frame 212 slides, it drives the first sliding rod 213 to move. The first sliding rod 213 is used to guide and limit the sliding of the first sliding frame 212. The first spring 214 provides the first sliding frame 212 with an elastic force away from the first fixed frame 211, so as to cooperate with the film peeling component 22 to realize the film peeling function.

[0037] The film peeling assembly 22 is provided with two groups and is symmetrically arranged along the vertical center plane of the first fixed frame 211. The film peeling assembly 22 includes a film peeling roller 221, a connecting arm 222, a first connecting rod 223, a first limit block 224, a second limit block 225 and a second connecting rod 226. The film peeling roller 221 is rotatably mounted on the end of the connecting arm 222 away from the first sliding frame 212. The end of the connecting arm 222 close to the first pushing assembly 21 is hinged to the first sliding frame 212. One end of the rod 223 is transmission-connected to the output end of the first linear drive 215, the other end of the first connecting rod 223 is hinged to the second connecting rod 226, and one end of the second connecting rod 226 away from the first connecting rod 223 is hinged to the side wall of the connecting arm 222. The first limit block 224 and the second limit block 225 are both installed on the first sliding frame 212, the first limit block 224 is used to limit the first connecting rod 223, and the second limit block 225 is used to limit the connecting arm 222.

[0038] When the first linear drive 215 is driven, the first connecting rod 223 connected to the output end of the first linear drive 215 is driven to deflect. In this process, the elastic force of the first spring 214 is first released to drive the first sliding frame 212 to move in the direction close to the dust-proof film, so that the surface of the film-peeling roller 221 installed on the connecting arm 222 contacts the dust-proof film and pushes the two ends of the dust-proof film to bulge outward. After the elastic force is released, the first linear drive 215 continues to drive. At this time, the first connecting rod 223 is driven by the first linear drive 215 to deflect, and the first connecting rod 223 drives the second connecting rod 226 to deflect, thereby pushing the connecting arm 222 to move in the first sliding frame. The movable frame 212 deflects, so that the film peeling roller 221 installed on the connecting arm 222 moves along the trajectory of the end of the connecting arm 222. The movement trajectory of the film peeling roller 221 first pushes against the two ends of the dust-proof film, and then moves toward the center in an arc-shaped trajectory, that is, the two film peeling rollers 221 move closer to each other toward the vertical center plane of the first fixed frame 211, and the dust-proof film applied on the dust-proof glass cover 13 is completely peeled off, so that the dust-proof film is separated from the surface of the dust-proof glass cover 13, and the separation operation is completed. In this process, the first limit block 224 and the second limit block 225 limit the deflection position of the first connecting rod 223 and the connecting arm 222 respectively, to ensure that the operation is accurate and correct.

[0039] The cleaning assembly 23 includes a second linear drive 231, a second fixed frame 232, a first pushing frame 233, a cleaning plate 234 and an alcohol storage tank 235. The second fixed frame 232 is fixedly mounted on the mounting frame 12, the second linear drive 231 is fixedly mounted on the second fixed frame 232, the driving direction of the second linear drive 231 is perpendicular to the driving direction of the first linear drive 215, the first pushing frame 233 is slidably arranged on the second fixed frame 232, the second linear drive 231 is fixedly mounted on the second fixed frame 232, the output end of the second linear drive 231 is transmission-connected to the first pushing frame 233, the cleaning plate 234 is mounted on the first pushing frame 233, and the alcohol storage tank 235 is mounted on the end of the second fixed frame 232 away from the dust-proof glass cover 13.

[0040] When the cleaning component 23 is working, the second linear drive 231 can push the first pushing frame 233 to slide on the second fixed frame 232, and the first pushing frame 233 drives the cleaning plate 234 installed thereon to move synchronously. During the movement, the application surface of the dust-proof glass cover 13 is cleaned with alcohol through the cleaning plate 234, so as to facilitate the subsequent application of the dust-proof film. The alcohol storage tank 235 is used to provide alcohol for the cleaning plate 234. Before wiping the cleaning plate 234, the cleaning plate 234 is first moved to the alcohol storage tank 235 to be dipped in a sufficient amount of alcohol.

[0041] The second fixed frame 232 is provided with a friction plate 2321, the first pushing frame 233 is provided with a third spring 2331, an elastic locking block 2332 and a rotating shaft 2333, the third spring 2331 and the elastic locking block 2332 are both installed on the side of the cleaning plate 234, the rotating shaft 2333 is horizontally arranged, the cleaning plate 234 is fixedly installed on the rotating shaft 2333, the third spring 2331 is vertically arranged and the top of the third spring 2331 is fixedly connected to the first pushing frame 233, the bottom end of the third spring 2331 is fixedly connected to the elastic locking block 2332, the cleaning plate 234 includes a cleaning cloth 2341, a locking ring tooth 2342 and a friction wheel 2343, the friction wheel 2343 and the locking ring tooth 2342 are both fixedly installed on the rotating shaft 2333, the friction wheel 2343 can fit with the friction plate 2321, the locking ring tooth 2342 is engaged with the elastic locking block 2332, and the cleaning cloth 2341 is fixedly installed on the rotating shaft 2333.

[0042] When the second linear drive 231 is driven, the first pushing frame 233 slides on the second fixed frame 232, so that the friction wheel 2343 installed on the rotating shaft 2333 fits with the friction plate 2321, and drives the rotating shaft 2333 to rotate 180 degrees during walking, thereby flipping the cleaning cloth 2341 to face upward. During this process, the third spring 2331 is compressed, and the elastic locking block 2332 and the locking ring tooth 2342 are unlocked. When the flipping is completed, the elastic locking block 2332 moves downward under the elastic force of the third spring 2331, realizing the locking function of the elastic locking block 2332 and the locking ring tooth 2342, thereby preventing the rotating shaft 2333 from deflecting, that is, ensuring the stability of the cleaning cloth 2341 during subsequent movement, which is convenient for subsequent wiping operations.

[0043] The first pushing frame 233 also includes a compression connecting rod 2334 and a fourth spring 2335. The cleaning component 23 also includes a third linear driver 236, a transmission connecting rod 237 and a resistance block 238. The third linear driver 236 is fixedly mounted on the second fixed frame 232. The output direction of the third linear driver 236 is opposite to the output direction of the second linear driver 231. The alcohol storage pool 235 is provided with a pool opening 2351. The pool opening 2351 is provided with a slidable sealing cover 2352. The output end of the third linear driver 236 is fixedly connected to the sealing cover 2352. One end of the transmission connecting rod 237 is fixedly connected to the sealing cover 2352. The fourth spring 2335 is sleeved on the compression connecting rod 2334, and the two ends of the fourth spring 2335 are respectively fixedly connected to the first pushing frame 233 and the compression connecting rod 2334.

[0044] When the cleaning cloth 2341 needs to be soaked in alcohol, the sealing cover plate 2352 fixedly connected thereto is driven to move linearly through the output of the third linear drive 236, so that the pool mouth 2351 leaks out, and the third linear drive 236 drives the transmission connecting rod 237 connected thereto to deflect during movement, thereby driving the resistance block 238 installed on the end of the transmission connecting rod 237 to move vertically downward, and the resistance block 238 squeezes the cleaning cloth 2341 located thereunder downward, overcomes the elastic force of the compression connecting rod 2334 to stretch the compression connecting rod 2334, thereby causing the rotating shaft 2333 and the cleaning plate 234 installed on the rotating shaft 2333 to descend into the pool mouth 2351, soaking the cleaning cloth 2341 in the alcohol inside the alcohol storage pool 235, completing the preparation work before wiping. It is worth mentioning that the use of alcohol can not only improve the cleaning effect of the surface of the dustproof glass cover 13 and prevent dust residue, but also improve the adhesion effect between the dustproof film and the surface of the dustproof glass cover 13 to prevent the occurrence of warping, bubbling, etc., which may affect the visual detection effect.

[0045] The applying assembly 24 includes a fourth linear drive 241, a third fixed frame 242, a second pushing frame 243 and an applying plate 244.

[0046] After the cleaning component 23 finishes cleaning the surface of the dust-proof glass cover 13, the clean dust-proof film is applied to the surface of the dust-proof glass cover 13 through the output of the application component 24, and the output of the fourth linear drive 241 drives the second pushing frame 243 to slide along the length direction of the third fixed frame 242. While moving, the second pushing frame 243 drives the application plate 244 connected thereto to be pushed forward synchronously, and the dust-proof film is applied to the surface of the dust-proof glass cover 13 through the application plate 244.

[0047] The third fixing frame 242 is provided with a slide rail 245 , a transmission limit rod 246 is installed on the side wall of the application plate 244 , an inclined chamfer 247 is provided at the end of the application plate 244 , and the application plate 244 is slidably matched with the third fixing frame 242 through the transmission limit rod 246 and the slide rail 245 .

[0048] Through the cooperation of the slide rail 245 and the transmission limit rod 246, the guiding and limiting functions of the sliding of the application plate 244 can be realized, and the application plate 244 can also move a certain distance towards the direction close to the dust-proof glass cover 13 after running a certain distance, so that the dust-proof film is tightly attached to the surface of the dust-proof glass cover 13, thereby improving the effect of the attachment. The inclined chamfer 247 can ensure that the dust-proof film smoothly enters between the application plate 244 and the dust-proof glass cover 13.

[0049] The film loading assembly 31 includes a mounting box 311, a connecting rotating joint 312, a second spring 313, a mounting rod 314 and a first rotating driver 315.
