Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and in particular relates to a profile side inspection device. Background Technology

[0002] Strip profiles are used in many products, such as the frames of photovoltaic modules, window frames, and the frames for edging sheet materials. After the strip profiles are cut, drilled, and chamfered, they need to be visually inspected. In order to improve the inspection efficiency and accuracy, it is urgent to design automated equipment to perform visual inspection on the profiles.

[0003] In the prior art, Chinese invention patent authorization announcement CN118527375B discloses a fully automatic frame inspection and palletizing device capable of inspecting both ends and the entire side of a photovoltaic module frame. When inspecting the side of the frame, a flipping mechanism is set on both sides of the feeding conveyor line. The flipping mechanism has several first frame clamping components, which are driven by a third motor to rotate simultaneously around a horizontal axis, causing several frames to rotate simultaneously, i.e., each frame rotates at the same angle. Each time, the frame rotates by a preset angle, then pauses to take a picture of that side. After taking the picture, it continues to rotate by a certain angle to complete the side inspection. In this solution, all frames rotate by the same angle each time, but the camera's field of view during actual photography is a conical opening and closing angle, such as... Figure 5 As shown, if the profile 200 has a groove 201 on its side, when all the profiles 200 are rotated by the same angle, the groove 201 of the middle profile 200 can face the camera directly, resulting in a clear image. However, for the profiles 200 on the sides, due to the conical opening angle of the field of view, there is a blind spot at the bottom of the groove 201. Figure 5 As shown in the shadow position, when several profiles are rotated at the same angle, the grooves 201 of the profiles 200 on both sides cannot be clearly photographed due to the blind spot, which will reduce the accuracy of the detection.

[0004] Therefore, it is necessary to provide a profile side inspection device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main objective of this invention is to provide a profile side inspection device that can adaptively adjust the rotation angle of different profiles to ensure that the interior of the profile is completely clear and without blind spots, thereby significantly improving the inspection accuracy and reliability.

The transmission assembly includes a first transmission wheel fixed at the output shaft end of the third drive member, a first rotating shaft rotatably disposed on the first mounting bracket, and a second transmission wheel fixed on the outer periphery of the first rotating shaft and synchronously transmitting power with the first transmission wheel.

[0009] Furthermore, the first mounting bracket is provided with a plurality of first sensors, the first sensors being corresponding to and located beside the first rotating shaft, and a detection plate for sensing by the first sensor is provided on the outer periphery of one end of the first rotating shaft.

[0010] Furthermore, the clamping assembly is fixed to the output shaft end of the third drive member.

[0011] Furthermore, a testing station is provided below the camera module, and the conveyor line is provided with several profile bearing positions at the testing station, with a second sensor for detecting the profile provided at each profile bearing position.

[0012] Furthermore, the blocking and positioning mechanism includes a fourth driving member, a second support plate driven by the fourth driving member to move up and down, and a plurality of first blocking blocks disposed on the second support plate and corresponding to the profile bearing position.

[0015] Furthermore, the camera module includes a plurality of cameras arranged in an array, and the plurality of cameras are mounted above the conveyor line via a support frame.

[0016] Compared with the prior art, the beneficial effects of this utility model's profile side inspection device are as follows: (1) It has efficient multi-section synchronous detection capability: by setting up multiple flip modules in conjunction with the camera, multiple profiles can be photographed and detected at the same time, which greatly improves the detection efficiency and is especially suitable for the online detection needs of batch profile production lines; (2) Flexible and adjustable flipping and shooting mechanism: Each flipping module can be controlled independently and can adaptively adjust the rotation angle of different profiles according to the actual position of the profile and the orientation of the groove, ensuring that there are no blind spots inside the groove and that it is completely clear to be photographed, which significantly improves the detection accuracy and reliability.

It is especially suitable for profile testing scenarios with high surface quality requirements. Attached Figure Description

Detailed Implementation

[0018] Please refer to Figures 1-6This embodiment is a profile side inspection device 100, which includes a conveyor line 1 for conveying profiles, a material blocking and separating mechanism 2 located at the input end of the conveyor line 1 for dividing the arranged profiles 200 into single pieces for forward input, a camera module 3 located above the conveyor line 1 for taking pictures of the profiles, a blocking and positioning mechanism 4 for blocking and positioning multiple profiles 200, and a pair of flipping mechanisms 5 located on both sides of the conveyor line 1 for driving the profiles to rotate around a horizontal axis. The pair of flipping mechanisms 5 respectively clamp the two ends of the profiles 200 to perform a flipping action on the profiles, so as to... It facilitates the inspection of the side of the profile 200; the flipping mechanism 5 includes a first driving member 51, a first support plate 52 driven by the first driving member 51 to move along the conveying direction perpendicular to the conveying line 1, a second driving member 53 disposed on the first support plate 52, a first mounting frame 54 driven by the second driving member 53 to move up and down, and a plurality of flipping modules 55 disposed on the first mounting frame 54. The flipping module 55 includes a clamping assembly 551 for clamping the end of the profile and a third driving member 552 for driving the clamping assembly 551 to rotate around a horizontal axis.

[0019] In this embodiment, profile 200 is a photovoltaic module frame. In other embodiments, profile 200 may be a product with a similar structure to the photovoltaic module frame. In this embodiment, the conveyed profile is a photovoltaic module frame, and conveyor line 1 is a belt conveyor. In other embodiments, conveyor lines with other structures can be replaced according to the actual profile being conveyed.

[0020] In this embodiment, the camera module 3 includes a plurality of cameras 31 arranged in an array. The cameras are mounted above the conveyor line 1 via a support frame 32. The arrangement or layout of the cameras 31 is determined according to the actual situation. In other embodiments, the camera module 3 is located below or to the side of the conveyor line 1. Therefore, the position of the camera module 3 and the layout of each camera are determined according to the actual situation and are not limited here.

[0021] In this embodiment, five flipping modules 55 are provided. The camera 31 can simultaneously photograph and inspect five profiles. Each flipping module 55 can clamp and drive one profile to flip individually. Therefore, based on the opening and closing angle of the cone shape below the camera 31, different angles can be flipped for profiles at different positions, so that the camera 31 can clearly photograph the surface and groove 201 of the profile 200, thereby improving the inspection accuracy of the profile. For example, as... Figure 6As shown, the profile located directly below the camera rotates at angle A so that the groove 201 faces the camera directly. The profiles on both sides rotate at angles B and C so that the groove 201 faces the camera directly. There are no blind spots within the groove 201, and the area within the groove 201 can be clearly captured. The sizes of angles A, B, and C are related to the placement, rotation direction, and location of the profile 200, and are not limited here; they can be set according to the actual situation.

[0022] In other embodiments, the number of flip modules 55 can be adjusted according to the actual detection range of the camera. Therefore, the number of flip modules 55 is not limited here, that is, the number of profiles 200 detected each time can be set according to the actual situation.

[0023] The clamping assembly 551 includes a clamping cylinder 5511 and a pair of clamping plates 5512 driven by the clamping cylinder 5511 to perform opening or clamping actions. In order to prevent the clamping plates 5512 from damaging the profile, protective blocks 5513 are provided on the inner clamping sides of the clamping plates 5512. The protective blocks 5513 are made of soft material to prevent the profile from being pinched. Preferably, the protective blocks 5513 are made of rubber.

[0024] In this embodiment, the clamping assembly 551 is mounted on the output shaft end of the third drive member 552 via the transmission assembly 553. The third drive member 552 is a rotary motor. Specifically, the transmission assembly 553 includes a first transmission wheel 5533 fixed to the output shaft end of the third drive member 552, a first rotating shaft 5531 rotatably mounted on the first mounting bracket 54, and a second transmission wheel 5532 fixed to the outer periphery of the first rotating shaft 5531 and synchronously driven with the first transmission wheel 5533. In this embodiment, the clamping cylinder 5511 is fixed to one end of the first rotating shaft 5531 via the connecting bracket 5534. In other embodiments, the clamping cylinder 5511 can be directly fixed to one end of the first rotating shaft 5531. Therefore, the connection method between the clamping cylinder 5511 and the first rotating shaft 5531 is not limited here.

[0025] In this embodiment, both the first transmission wheel 5533 and the second transmission wheel 5532 are gears, and the two gears mesh to achieve rotational transmission. In other embodiments, both the first transmission wheel 5533 and the second transmission wheel 5532 are pulleys, and a gap is formed between the first transmission wheel 5533 and the second transmission wheel 5532. A synchronous belt is wound around the first transmission wheel 5533 and the second transmission wheel 5532 to achieve rotational transmission.

[0026] The first rotating shaft 5531 is rotatably mounted on the first mounting bracket 54 via a bearing. In order to monitor the rotation angle of the first rotating shaft 5531 in real time, a number of first sensors 56 are provided on the first mounting bracket 54. The number of first sensors 56 corresponds one-to-one with the number of first rotating shafts 5531, and the first sensors 56 are located beside the first rotating shaft 5531. A detection piece 57 for sensing by the first sensor 56 is provided on the outer periphery of one end of the first rotating shaft 5531.

[0027] In other embodiments, the clamping assembly 551 is fixed to the output shaft end of the third drive member 552, and the third drive member 552 directly drives the clamping assembly 551 to rotate, which simplifies the structure of the flipping module 55.

[0028] Both the first drive unit 51 and the second drive unit 53 are linear motors. The first drive unit 51 is designed to allow the clamping assembly 551 to move closer to or further away from the end of the profile to perform clamping or releasing actions, and it can also move left and right to adapt to profiles of different lengths, thereby improving the versatility of the detection device. The second drive unit 53 is designed to drive the profile 200 on the conveyor line 1 to rise to a set height so that the profile can perform subsequent rotation actions.

[0029] A detection station is located below the camera module 3. A stop and positioning mechanism 4 is located at the detection station. The conveyor line 1 has several profile bearing positions at the detection station, and a second sensor 44 for detecting the profile is located at each profile bearing position. The stop and positioning mechanism 4 includes a fourth driving component 41, a second support plate 42 driven by the fourth driving component 41 to move up and down, and several first blocking blocks 43 located on the second support plate 42 and corresponding to the profile bearing positions. The fourth driving component 41 is a motor or a cylinder. The profiles are separated into individual pieces and transported to the inspection station. When the second sensor 44 on each profile bearing position detects the presence of profile 200, the fourth drive unit 41 drives the second support plate 42 to move several first blocking blocks 43 upward and extend between the two profiles. Then the conveyor line 1 moves forward a set distance, so that each profile can achieve the front and rear position correction of a group of multiple profiles by relying solely on the first blocking block 43, restricting the profiles on each profile bearing position, so that the subsequent flipping mechanism 5 can accurately clamp the group of multiple profiles as a whole, thereby ensuring the inspection accuracy of the camera module 3.

[0030] The material blocking and separating mechanism 2 includes a blocking module 21 that blocks profiles on the conveyor line 1 at the first profile position at the very front of the conveyor; a third sensor 22 that detects whether there are profiles at the first profile position; a fourth sensor 23 that detects whether there are profiles at the second profile position; a baffle plate 24 located above the junction of the first and second profile positions; and a first cylinder 25 that drives the baffle plate 24 downward when both the third sensor 22 and the fourth sensor 23 detect a profile signal. The first profile position is the position at the very front of the conveyor line that carries the first profile, and the second profile position is the position at the front of the conveyor line that carries the second profile. The blocking module 21 includes a blocking cylinder 211 and a blocking plate 212 that is driven by the blocking cylinder 211 to move up, down, or rotate.

[0031] In this embodiment, a straightening mechanism 6 for straightening the profile 200 is also provided on both sides of the material blocking and separating mechanism 2. The straightening mechanism 6 includes a straightening cylinder 61 and a straightening plate 62 driven by the straightening cylinder 61 to move closer to or away from the end of the profile. Both the material blocking and separating mechanism 2 and the straightening mechanism 6 are mounted on the frame.

[0032] The conveyor line 1 continuously inputs profiles. The input profiles are first blocked by the stop module 21 in the material blocking and separation mechanism 2. When the third sensor 22 detects a profile signal but the fourth sensor 23 does not detect a profile signal, the stop plate 24 remains in a high position. When both the third sensor 22 and the fourth sensor 23 detect a profile signal, the stop plate 24 descends to a low position, blocking the profile at the second profile position, ensuring that only one profile is sent to the inspection station at a time. When the third sensor 22 detects an inspection station signal, the two alignment plates 62 extend simultaneously to align the positions of both ends of the profile 200, providing a positional accuracy basis for subsequent visual inspection of the profile, thus ensuring the accuracy of the inspection.

[0033] When using the profile side inspection device 100 provided in this solution, the conveyor line 1 continuously inputs profiles, with both ends of the profiles extending beyond the sides of the conveyor line 1 to facilitate clamping the ends of the profiles by the clamping assembly 551. The input profiles are first blocked by the stop module 21 in the stop separation mechanism 2. When the third sensor 22 detects a profile signal but the fourth sensor 23 does not, the stop plate 24 remains in a high position. When both the third sensor 22 and the fourth sensor 23 detect a profile signal, the stop plate 24 descends to a low position, blocking the profile at the second profile position, ensuring that only one profile is fed into the inspection station at a time. When the third sensor 22 detects a profile signal... After the signal from the measuring station is received, two straightening plates 62 extend simultaneously to straighten the positions of both ends of the profile 200. The straightened profile 200 is then conveyed to the testing station. When the second sensor 44 at each profile bearing position detects the presence of the profile 200, the fourth drive unit 41 drives the second support plate 42 to raise and extend several first blocking blocks 43 between the two profiles. Then, the conveyor line 1 moves forward a set distance, so that each profile is straightened by the first blocking block 43 alone, thus restricting the profiles at each bearing position. The first drive unit 51 drives the first support plate 52 to move several flipping modules 55 closer to the ends of the profile 200. The clamping cylinder 5511 drives the clamping plate 5512 to clamp the end of the profile. The second driving component 53 drives the first mounting bracket 54 to raise several profiles to a set height. Several third driving components 552 drive their respective clamping components 551 to rotate the profile 200 by a first set set angle. The camera 31 takes a picture of the first side of the profile. After the picture is taken, the several third driving components 552 drive their respective clamping components 551 to rotate the profile 200 by a second set set angle. The camera 31 takes a picture of the second side of the profile. The profile is rotated and photographed in sequence until the side of the profile is completely photographed, thus completing the side inspection of the profile. Then the receiving and transfer mechanism (not shown in the figure) is used. (i) Transfer the inspected profiles to other positions. While the flipping mechanism 5 is positioned above the conveyor line 1 and taking pictures of the profiles, profiles are continuously transported to the inspection station on the conveyor line 1 and positioned by the stop and positioning mechanism 4. After the inspected profiles above are transferred away, the flipping mechanism 5 descends to continue clamping several profiles for the next round of inspection. The first set of angles can be set to the same as or different from the second set of angles, depending on the actual situation. Since several flipping modules 55 can clamp multiple profiles at a time, and each profile can rotate independently, and some profiles have different rotation angles, each set of angles includes multiple rotation angles, such as... Figure 6As shown, however, its specific rotation angle is set according to the actual situation and is not limited here; the material receiving and transfer mechanism is set at the output end of the conveyor line 1. The material receiving and transfer mechanism is not shown in this embodiment. You can refer to the material receiving and transfer mechanism in a fully automatic edge detection and palletizing equipment disclosed in Chinese Invention Patent Announcement CN118527375B. It will not be described in detail here.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
