Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically a six-sided visual inspection device. Background Technology

[0002] Visual appearance inspection is a non-contact inspection method that uses industrial cameras, light sources, image processing algorithms, and artificial intelligence (especially deep learning) to collect and analyze images of product surfaces or appearances in real time in order to identify defects, flaws, or whether they conform to design specifications.

[0003] Specifically, in the visual inspection process of some 3D products, it is necessary to inspect multiple sides of the workpiece. This requires rotating and flipping the product during the inspection process, followed by photographic inspection. To achieve this function, currently, the product is continuously transported by a conveyor belt, and a flipping or rotating mechanism is set up on the side of the conveyor belt. After one side is inspected at one station, it is transported to the next station by the conveyor belt, where the product is flipped or rotated again, and then photographed. In the above process, the product moves by the conveyor belt, and each station must start and stop. Due to inertia, the product's position will deviate during frequent starts and stops. This causes the flipping or rotating device to frequently realign, making the control program more complex and requiring more advanced flipping and rotating devices, thus increasing the investment. In addition, the deviation will also lead to a deterioration in the photographic inspection effect. Utility Model Content

[0004] (I) Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model provides a six-sided visual inspection device.

[0006] The specific technical solution is as follows: a six-sided visual inspection device, including a lifting mechanism, a conveying mechanism, a flipping mechanism and an inspection mechanism;

[0007] The lifting mechanism includes a cylinder and a lifting platform. The upper part of the lifting platform is provided with several platforms for placing workpieces at equal intervals. The conveying mechanism includes a linear module, a motor, a mounting plate, and grippers. The motor is used to drive the linear module. The mounting plate is fixed on the slider of the linear module. The mounting plate is provided with multiple grippers at equal intervals. The distance between two adjacent grippers is the same as the distance between two adjacent platforms. When the cylinder lifts the lifting platform, the multiple grippers simultaneously clamp the workpieces on the multiple platforms and transport them to the top of another platform under the drive of the linear module.

[0008] The flipping mechanism includes a rotating gripper and a third linear module that drives the rotating gripper to reciprocate. When the cylinder lifts the lifting platform, the rotating gripper grabs the workpiece on the platform and moves to the next platform under the drive of the third linear module. During the movement, the rotating gripper flips horizontally by 180 degrees.

[0009] A rotary cylinder is also provided on a platform. When the workpiece is placed on the rotary cylinder by the gripper, the rotary cylinder rotates 90 degrees.

[0010] The detection mechanism includes six camera modules, which are respectively located on the front and rear platforms of the rotating gripper for detecting the top and bottom surfaces of the workpiece; the front and rear sides of the two platforms at the front end of the rotating cylinder are used to detect the two sides of the workpiece; the front and rear sides of the two platforms at the rear end of the rotating cylinder are used to detect the other two sides of the workpiece.

[0011] Furthermore, there are two conveying mechanisms: a first conveying mechanism and a second conveying mechanism. The first conveying mechanism includes a first linear module, a first motor, a first mounting plate, and a first gripper. The first motor drives the first linear module, the first mounting plate is fixed to the slider of the first linear module, and multiple grippers are fixed to the first mounting plate at equal intervals. The first grippers are horizontally positioned, and a camera module for detecting the upper and lower surfaces of the workpiece is located above the first gripper.

The second motor drives the second linear module, the second mounting plate is fixed to the slider of the second linear module, and multiple grippers are fixed to the second mounting plate at equal intervals. The second grippers are vertically positioned, and a camera module for detecting the four sides of the workpiece is located on the front and rear sides of the second gripper.

[0012] Furthermore, there are two lifting mechanisms, namely a first lifting mechanism and a second lifting mechanism. The first lifting mechanism includes a first cylinder and a first lifting platform. The first lifting platform is fixed to the head end of the first cylinder. The extension and retraction of the first cylinder drives the first lifting platform to move up and down. The second lifting mechanism includes a second cylinder and a second lifting platform. The second lifting platform is fixed to the head end of the second cylinder. The extension and retraction of the second cylinder drives the second lifting platform to move up and down. The first lifting platform and the second lifting platform are provided with multiple carriers, and the positions of the multiple camera modules correspond to the positions of the multiple carriers.

[0013] Furthermore, the first lifting mechanism corresponds to the first transport mechanism, and the second lifting mechanism corresponds to the second transport mechanism. The first gripper at the front end of the first transport mechanism is used to grip and transport the workpiece from the previous section to the platform at the front end of the first lifting platform. The gripper at the front end of the second transport mechanism is used to grip and transport the workpiece from the last platform of the first lifting platform to the platform at the front end of the second lifting platform.

[0014] Furthermore, the first lifting platform has five platforms and four grippers. The first grippers and the rotating grippers are located on the same horizontal line. Two first grippers are provided on each side of the rotating gripper. The distance between the two first grippers on the left and right sides of the rotating gripper is the same as the distance from the rotating gripper to the two adjacent first grippers and the distance between the two adjacent platforms on the first lifting platform.

[0015] Furthermore, the number of second grippers is four and they are equally spaced, the number of second lifting platforms is three, and the rotary cylinder is fixed on the platform of the second lifting platform closest to the first lifting platform. The distance between two adjacent second grippers, the distance between two adjacent platforms on the second lifting platform, and the distance between the last platform on the first lifting platform and the foremost platform on the second lifting platform are all the same.

[0016] Furthermore, the six camera modules are respectively fixed above the first and third platforms on the first lifting platform; the side of the last platform on the first lifting platform; and the sides of the three platforms on the second lifting platform.

[0020] (2) Take a picture during the gripper gripping. This only requires the camera and the gripper reciprocating terminal to be initially aligned.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] To address the problems existing in the relevant prior art, this utility model proposes a six-sided visual inspection device. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0030] A six-sided visual inspection device includes a lifting mechanism, a conveying mechanism, a flipping mechanism, and an inspection mechanism;

[0031] The lifting mechanism includes a cylinder 1 and a lifting platform 2. The bottom of the lifting platform is fixed to the upper part of the cylinder's telescopic rod. The cylinder is vertically positioned, so the extension and retraction of the cylinder can drive the lifting platform 2 to move up and down. Linear guide rails are set on both sides of the lifting platform for guidance, and the two linear guide rails are vertically fixed by a fixing plate, which ensures that the lifting platform 2 rises and falls stably in the vertical direction. Several platforms 3 for placing workpieces are evenly spaced on the upper part of the lifting platform 2. The conveying mechanism includes a linear module 4, a motor 5, a mounting plate 6, and grippers 7. The linear module 4 is a commonly used mechanical module. The motor 5 drives the linear module 4 to realize the movement of the slider of the linear module 4. A photoelectric switch is set on the side of the slider and connected to the motor 5 to control the motor 5 to change the direction of rotation, thus realizing the movement of the linear module. The reciprocating motion of the slider, the mounting plate 6 is fixed on the slider of the linear module 4, and the mounting plate 6 is provided with multiple grippers 7 at equal intervals. The distance between two adjacent grippers 7 is the same as the distance between two adjacent platforms 3. When the cylinder 1 lifts the lifting platform 2, the multiple grippers 7 simultaneously clamp the workpieces on the multiple platforms 3 and transport them to the next platform 3 under the drive of the linear module 4. Then the grippers 7 are released and the workpiece is placed on the corresponding platform. Next, the cylinder 1 drives the lifting platform to retract, and the linear module 4 drives the grippers back to the initial position. The above actions are repeated. The multiple grippers 7 clamp the parts on the corresponding platform 3 and transport them to the next platform through reciprocating motion, realizing this step-by-step conveying method. Through this conveying method, the conveying distance can be guaranteed to be fixed each time, and there will be no deviation.

[0032] The flipping mechanism includes a rotating gripper 8 and a third linear module 9 that drives the rotating gripper 8 to reciprocate. When the cylinder 1 lifts the lifting platform 2, the rotating gripper 8 grabs the workpiece on the platform 3 and moves to the next platform 3 under the drive of the third linear module 9. During the movement, the rotating gripper 8 flips horizontally by 180 degrees. At the same time, the third linear module is also connected to a drive motor to drive the linear module to work normally. A photoelectric switch is also provided on the third linear module to control the slider of the third linear module to achieve reciprocating motion. No specific limitation is made here. In the above scheme, the rotating gripper 8 reciprocates between two adjacent platforms to grab the workpiece, and flips it by 180 degrees during the process to achieve flipping. This can be used in conjunction with the detection mechanism to detect the upper and lower sides of the workpiece.

[0033] A rotary cylinder 10 is also provided on a platform 3. When the workpiece is placed on the rotary cylinder 10 by the gripper, the rotary cylinder rotates 90 degrees. By setting a rotary cylinder 10 that can rotate 90 degrees on a platform 3, the workpiece will be rotated 90 degrees by the rotary cylinder when it passes the platform. Thus, detection mechanisms are set on the two platform sides at the front end of the rotary cylinder to detect the two symmetrical sides, and detection mechanisms are set on the two platform sides at the rear end of the rotary cylinder to detect the other two sides.

[0034] The inspection mechanism includes six camera modules 11, each positioned above the front and rear platforms of the rotating gripper 8, for inspecting the top and bottom surfaces of the workpiece; the two platforms 3 at the front end of the rotating cylinder 10 are positioned at the front and rear sides for inspecting the two sides of the workpiece; the two platforms at the rear end of the rotating cylinder 10 are positioned at the front and rear sides for inspecting the other two sides of the workpiece. When the gripper 8 picks up the workpiece, the camera modules 11 take pictures of the workpiece at each corresponding position for inspection. That is, inspection is performed after the workpiece is picked up, rather than placing the workpiece on the platform for inspection. Through the above settings, all six sides of the workpiece are inspected. The workpiece is picked up by the gripper and then transported by the linear module, making the transport distance more precise and controllable each time, without deviation. In addition, the camera modules 11 correspond to the positions of each gripper, that is, the picture is taken when the gripper picks up the workpiece. This only requires ensuring the initial alignment of the camera and the reciprocating end of the gripper, and no counter-alignment is required during the process, which can ensure the accuracy of the picture and the work efficiency. The linear inspection and transport mechanism is also suitable for batch inspection.

[0035] In the above scheme, there are two conveying mechanisms, namely a first conveying mechanism and a second conveying mechanism. The first conveying mechanism includes a first linear module 4a, a first motor 5a, a first mounting plate 6a, and first grippers 7a. The first motor 5a drives the first linear module 4a. The first mounting plate 6a is fixed to the slider of the first linear module 4a. Multiple first grippers 7a are fixed to the first mounting plate 6a at equal intervals. The first grippers 7a are horizontally set. The camera module 11 for detecting the upper and lower surfaces of the workpiece is located above the first grippers 7a. By setting the first grippers 7a horizontally and then setting the camera module 11 above the first grippers 7a, the upper surface of the workpiece can be photographed and detected. At the same time, by cooperating with the rotating gripper to flip the workpiece, two downward-facing camera modules can photograph and detect the upper and lower surfaces of the workpiece respectively. The second conveying mechanism includes a second linear module 4b, a second motor 5b, a second mounting plate 6b, and a second gripper 7b. The second motor 5b drives the second linear module 4b. The second mounting plate 6b is fixed to the slider of the second linear module 4b. Multiple grippers 7b are fixed to the second mounting plate 6b at equal intervals. The grippers 7b are vertically arranged. The camera module 11 for detecting the four sides of the workpiece is located on the front and rear sides of the gripper 7b. In the above scheme, since it is necessary to take pictures of the sides of the workpiece, and the first gripper 7a in the first conveying mechanism needs to cooperate with the upper and lower sides for picture detection, it can only perform horizontal gripping. At the same time, when it is necessary to take pictures of the sides, the second conveying mechanism needs to be set up with the second gripper vertically arranged. This facilitates the picture detection of the sides and does not cause the gripper to block the detection surface.

[0036] Correspondingly, there are two lifting mechanisms: a first lifting mechanism and a second lifting mechanism. The first lifting mechanism includes a first cylinder 1a and a first lifting platform 2a. The first lifting platform 2a is fixed to the head end of the first cylinder 1a. The extension and retraction of the first cylinder 1a drives the first lifting platform 2a to move up and down. Simultaneously, the side of the first lifting platform 2a is provided with a vertical linear guide rail for guidance. The second lifting mechanism also includes a second cylinder 1b and a second lifting platform 2b. The second lifting platform 2b is fixed to the head end of the second cylinder 1b. The extension and retraction of the second cylinder 1b drives the second lifting platform 2b to move up and down. Multiple carriers 3 are provided on the first lifting platform 2a and the second lifting platform 2b, and the positions of multiple camera modules 11 correspond to the positions of multiple carriers 3. Furthermore, the first lifting mechanism corresponds to the first transport mechanism, and the second lifting mechanism corresponds to the second transport mechanism. That is, the first lifting platform 2a in the first lifting mechanism... The upper platform 3 corresponds vertically to the first gripper 7a in the first conveying mechanism. The platform 3 on the second lifting platform 2b in the second lifting mechanism corresponds vertically to the second gripper 7b in the second conveying mechanism. The first gripper 7a reciprocates between two adjacent platforms 3 on the first lifting platform 2a under the drive of the first linear module. The second gripper 7b also reciprocates between two adjacent platforms on the second lifting platform under the drive of the second linear module. The first gripper 7a at the front end of the first conveying mechanism is used to clamp and transport the workpiece from the previous section to the platform 3 at the front end of the first lifting platform 2a. The second gripper 7b at the front end of the second conveying mechanism is used to grab and transport the workpiece on the last platform 3 of the first lifting platform 2a to the platform 3 at the front end of the second lifting platform 2b. The above process completes the loading and the connection between the first and second lifting platforms.

[0037] Specifically, the first lifting platform 2a has five platforms, which are designated as the first, second, ... fifth platforms, with the end furthest from the second lifting platform 2b as the front end and the other end as the rear end. The number of first grippers 7a is four, designated as the first, second, ... fourth first grippers 7a. The first grippers 7a and the rotating gripper 8 are on the same horizontal line, with two first grippers 7a on each side of the rotating gripper 8. The distance between the two first grippers 7a on the left and right sides of the rotating gripper 8, and the distance from the rotating gripper 7a to the two adjacent first grippers 7a are specified. The distances between adjacent platforms 3 on the first lifting platform 2a and the first lifting platform 2a are all the same. In the above configuration, the first first gripper 7a can pick up and transport the workpiece from the previous section to the first platform 3, the second first gripper picks up and transports the workpiece on the first platform to the second platform, the rotating gripper 8 picks up and transports the workpiece on the second platform 3 to the third platform, and at the same time, the rotating gripper rotates the workpiece horizontally by 180 degrees, the third first gripper picks up and transports the workpiece on the third platform to the fourth platform, and the fourth first gripper picks up and transports the workpiece on the fourth platform to the fifth platform.

[0038] There are four second grippers 7b, which are equally spaced and referred to as the first, second, third, and fourth second grippers 7b for ease of explanation. There are three platforms on the second lifting platform, which are referred to as the sixth, seventh, and eighth platforms 3 for ease of explanation. The rotating cylinder 10 is fixed on the platform closest to the first lifting platform on the second lifting platform, i.e., the sixth platform 3. The distance between two adjacent second grippers, the distance between two adjacent platforms on the second lifting platform, and the distance between the last platform on the first lifting platform and the foremost platform on the second lifting platform are all the same. With the above settings, the first second gripper 7b moves the workpiece from the fifth platform to the sixth platform. When the workpiece is placed on the rotating cylinder of the sixth platform, the rotating cylinder rotates the workpiece 90 degrees. The second second gripper moves the workpiece on the rotating cylinder to the seventh platform, and so on. Finally, the fourth second gripper picks up the workpiece from the eighth platform and transports it to the next section.

[0039] Six camera modules are fixed above the first and third platforms on the first lifting platform. Two camera modules are also located on each side of the second lifting platform, along with the last platform on the first lifting platform and the sides of the three platforms on the second lifting platform. These six camera modules are responsible for detecting the six sides of the workpiece. This is achieved through the following steps: During the entire movement, when the gripper moves horizontally, the cylinder drives the lifting platform to retract and descend. When the gripper moves to a designated position to pick up the workpiece, the cylinder drives the corresponding lifting platform to rise for easy gripping. The horizontal movement of the workpiece relies on the linear module to drive the corresponding gripper to move horizontally. That is, the first gripper picks up the workpiece and places it on a platform, the second gripper picks up the workpiece on that platform and transports it to the next platform before releasing it. This process is repeated so that the workpiece passes through a total of eight platforms on the first and second lifting platforms. During the movement, the six sides of the workpiece are detected. Specifically, when the first gripper picks up the workpiece and transports it directly above the first platform, a photograph is taken of the workpiece. When the rotating gripper flips the workpiece and transports it directly above the third platform, the second camera module... The back of the workpiece is photographed for inspection. When the fourth first gripper transports the workpiece to the top of the fifth platform, the third camera module inspects one side of the workpiece. When the first second gripper transports the workpiece to the top of the fifth platform, the fourth camera module inspects the other side of the workpiece. The inspected workpiece is then placed on a rotary cylinder and rotated 90 degrees. The second second gripper picks up the rotated workpiece and transports it to the top of the seventh platform. At this point, the fifth camera module inspects the third side. The third second gripper picks up the workpiece from the first platform and moves it to the top of the eighth platform. At this point, the sixth camera module inspects the fourth side of the workpiece. Finally, the fourth second gripper picks up the workpiece from the eighth platform and transports it to the next stage. During the above process, photographic inspection is performed when the grippers pick up the workpiece. This only requires ensuring the initial alignment of the camera and the gripper's reciprocating end; no reverse alignment is needed during the process, which ensures photographic accuracy and work efficiency. The specific detection of the workpiece reaching the designated position can be achieved through a PLC control system, which is common knowledge in this field and will not be described in detail here.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
