Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection, in particular to a double-sided intelligent visual inspection and error correction machine. Background Technique

[0002] An intelligent visual inspection and error correction machine is a device that combines machine vision technology and intelligent algorithms. It can quickly and accurately analyze and detect images of various products or production processes, so as to discover defects, errors or abnormalities and perform timely error correction processing.

[0003] At present, most of the items to be tested are conveyed to the lower part of the industrial camera through a transmission mechanism, and the industrial camera in the middle takes pictures of the items to be tested. If the item to be tested is not in the centered position, it will affect the integrity of the shooting.

[0004] The existing public technical solution, with the publication number of CN217820054U, discloses an intelligent visual on-line inspection device. Its technical solution is: including a concave table and a conveyor belt mechanism arranged on the concave table, and also including a detection component fixedly installed above the middle of the concave table, a second infrared sensor fixedly installed at one end of the concave table, and a correction mechanism. The correction mechanism includes square plates symmetrically and fixedly installed on both sides of one end of the concave table close to the second infrared sensor and two sets of pusher components arranged in the two sets of square plates, realizing automatic straightening of the parts before detection, so that the parts are in the middle position of the conveyor belt mechanism, thus ensuring that the detection component can completely collect the images of the parts, improving the accuracy of the detection device for part detection, and avoiding the phenomenon that unqualified products flow into the market and bring negative impacts to the manufacturer, with a high degree of intelligence.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4, A double-sided intelligent vision detection and error correction machine, including a base 1. The four corners of the top of the base 1 are installed with a top plate 2 through vertical rods, and a conveyor belt 3 is arranged between the base 1 and the top plate 2. A lifting component 5 for adjusting the height is arranged below the conveyor belt 3, and an industrial camera 7 for shooting is arranged above the conveyor belt 3. A flipping component 4 for flipping workpieces is arranged on the lifting component 5;

[0028] The flipping component 4 includes a clamping piece 401 installed above the conveyor belt 3. A clamping plate 412 is arranged on one side of the clamping piece 401 close to the vertical center line of the conveyor belt 3. The power output end of a flipping motor 413 is installed in the middle of the clamping plate 412. The flipping motor 413 is fixed inside the clamping piece 401. A clamping screw rod 403 is arranged on one side of the clamping piece 401 far from the vertical center line of the conveyor belt 3. A screw rod sleeve 405 is installed outside the clamping screw rod 403. An activity hole 411 is arranged at the connection between the screw rod sleeve 405 and the clamping piece 401, and the clamping screw rod 403 penetrates through the inside of the activity hole 411;

[0029] The flipping component 4 further includes a first sprocket 406 installed at the end of the clamping screw rod 403. A second sprocket 408 is arranged below the first sprocket 406. A chain belt 407 is arranged on the surfaces of the second sprocket 408 and the first sprocket 406. The middle of the second sprocket 408 is fixedly connected with an output shaft 409, and the end of the output shaft 409 is connected with the power output end of a two-way motor 410. Support rods 402 penetrating through the inside of the clamping piece 401 are arranged on both the left and right sides of the clamping screw rod 403, and a guiding hole 404 is opened at the connection between the support rod 402 and the clamping piece 401.

[0030] By adopting the above technical solution, the workpiece moves to below the industrial camera 7 through the conveyor belt 3. At this time, the two-way motor 410 is started. The power output end of the two-way motor 410 drives the output shaft 409 to rotate. Thus, the first sprocket 406 can be driven to rotate by the second sprocket 408 and the chain belt 407. Under the action of the first sprocket 406, the clamping screw rod 403 is driven to rotate. Thus, the screw rod sleeve 405 drives the clamping piece 401 to move on the clamping screw rod 403. The clamping piece 401 approaches the workpiece until the clamping plate 412 clamps the workpiece. Since the structures of the two clamping pieces 401 are the same, when clamping the workpiece, the workpiece moves to the central position. The industrial camera 7 shoots the workpiece. The industrial camera 7 transmits the data to the image processing device through a cable to realize vision detection. Once an error is found, an alarm device will give an alarm. After single-sided detection, the lifting component 5 can be used to push the flipping component 4 to move upward, driving the workpiece to move upward. The flipping motor 413 drives the clamping plate 412 to rotate, driving the workpiece to flip through the clamping plate 412 to detect the other side.

[0031] Specifically, such as Figure 4As shown in the figure, the lifting assembly 5 includes a supporting cross plate 502 arranged below the conveyor belt 3, and the telescopic end of a lifting hydraulic cylinder 501 is fixedly arranged at the bottom of the supporting cross plate 502. Supporting vertical plates 503 are arranged on the left and right sides of the supporting cross plate 502. The first sprocket 406, the second sprocket 408 and the chain belt 407 are all arranged inside the supporting vertical plates 503. A bidirectional motor 410 and an output shaft 409 are both arranged inside the supporting cross plate 502. A support frame 6 fixed between the base 1 and the top plate 2 is arranged outside the supporting vertical plates 503. A guiding slider 504 is arranged at the connection between the supporting vertical plates 503 and the support frame 6, and a guiding chute 505 adapted to the guiding slider 504 is arranged on the surface of the support frame 6.

[0032] By adopting the above technical solution, after the lifting hydraulic cylinder 501 is started, it can push the supporting cross plate 502 to move upward, driving the supporting vertical plates 503 to slide on the support frame 6. Thus, the flipping assembly 4 can be driven to move upward by the supporting cross plate 502 and the supporting vertical plates 503, moving the workpiece away from the conveyor belt 3, providing space for flipping the workpiece, facilitating the flipping of the workpiece. An infrared sensor for detecting the position of the workpiece, a controller for controlling the sensor and other devices, and an image processor for processing images can be arranged on the base 1. These devices are all existing devices, and the specific working principle can be based on the content recorded in the publication number CN217820054U, which will not be elaborated here.

[0033] Working principle: The workpiece moves to below the industrial camera 7 through the conveyor belt 3. At this time, the bidirectional motor 410 is started, and the power output end of the bidirectional motor 410 drives the output shaft 409 to rotate. Thus, the first sprocket 406 can be driven to rotate by the second sprocket 408 and the chain belt 407. Under the action of the first sprocket 406, the clamping lead screw 403 is driven to rotate. Then, the lead screw sleeve 405 drives the clamping member 401 to move on the clamping lead screw 403, and the clamping member 401 approaches the workpiece until the clamping plate 412 clamps the workpiece. Since the two groups of clamping members 401 have the same structure, when clamping the workpiece, the workpiece moves to the centered position, and the industrial camera 7 takes pictures of the workpiece. The industrial camera 7 transmits the data to the image processing device through a cable to realize visual inspection. Once an error is found, an alarm device will give an alarm. After one-sided inspection, after the lifting hydraulic cylinder 501 is started, it can push the supporting cross plate 502 to move upward, driving the supporting vertical plates 503 to slide on the support frame 6. Thus, the flipping assembly 4 can be driven to move upward by the supporting cross plate 502 and the supporting vertical plates 503, moving the workpiece away from the conveyor belt 3, and the flipping motor 413 drives the clamping plate 412 to rotate, driving the workpiece to flip through the clamping plate 412 to inspect the other side, without manually turning the workpiece over again and then placing it on the conveyor belt 3, improving work efficiency.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
