Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and in particular relates to a profile 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, which can detect the two ends of the photovoltaic module frame and the entire side, but it still has the following problems: (1) When inspecting the side of the frame, a flipping mechanism is set on both sides of the feeding conveyor line. The flipping mechanism is equipped with several first frame clamping components, and the several first frame clamping components are driven by the third motor to rotate around the horizontal axis at the same time, causing several frames to rotate at the same time. In this scheme, all frames rotate by the same angle each time. However, when the camera actually takes pictures, its field of view is a conical opening and closing angle, such as Figure 5 As shown, if the profile 600 has a groove 601 on its side, when all the profiles 600 are rotated by the same angle, the groove 601 of the middle profile 600 can face the camera directly, allowing for clear photography. However, for the profiles 600 on the sides, due to the camera's field of view being a conical opening angle, there is a blind spot at the bottom of the groove 601. Figure 5 As shown in the shadow position, when several profiles are rotated at the same angle, the grooves 601 of the profiles 600 on both sides cannot be clearly photographed due to the blind spot, which will reduce the accuracy of the detection. (2) After inspection, defective products are placed together on the waste discharge conveyor line. The defective products are not classified, and the actual defect type of the frame is not clear, which is not conducive to the improvement of the frame quality. Moreover, if frames with different types of defects are placed together, some frames with dirt defects will be contaminated again. If there are only some dirt defects on the frame, they can be wiped and reused after wiping. However, the defective products are not classified, and it is time-consuming and inefficient to find the dirty defective frames from a whole pile of defective products. (3) The reject handling mechanism is equipped with only one gripper, which can only grip one frame at a time. If there are multiple defective products in the same group of inspection frames, it is necessary to grip them multiple times, resulting in very low handling efficiency.

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

Detailed Implementation

[0018] Please refer to Figures 1-10This embodiment is a profile inspection device 100, which includes a feeding conveyor line 80, a receiving conveyor mechanism 40, and a discharging conveyor line 90 connected in sequence. Along the conveying direction of the feeding conveyor line 80 are arranged a material blocking separation mechanism 1 for dividing the arranged profiles 600 into single pieces for forward input, a first alignment mechanism 2 for aligning the two ends of the profiles, an end inspection device 50 for inspecting the two ends of the profiles, and a side inspection device 70 for inspecting the sides of the profiles. The end inspection device 50 includes a first camera module 20 for taking pictures of the profile ends and a first stop positioning mechanism 3 for blocking and positioning the profile 600. The side inspection device 70 includes a second camera module 30 for taking pictures of the profile sides and a first stop positioning mechanism 3 for blocking and positioning the profile 600. The second stop positioning mechanism 4 for blocking positioning and a pair of flipping mechanisms 5 set on both sides of the feeding conveyor line 80 and driving the profile to rotate around the horizontal axis; the receiving conveyor mechanism 40 includes a conveying unit 7 connected to the discharge conveyor line 90 and a receiving unit 6 that receives the profile after side inspection and transfers the profile to the conveying unit 7; a classification and stacking mechanism 8 for classifying and stacking defective products of different types and a handling mechanism 9 for transporting defective products on the discharge conveyor line 90 to the classification and stacking mechanism 4 or for transporting reworked and qualified profiles on the classification and stacking mechanism 4 to the discharge conveyor line 90 are provided above the discharge conveyor line 90. The first camera module 20, the second camera module 30 and the handling mechanism 9 are all electrically connected to the image processing unit.

[0019] In this embodiment, the profile 600 being tested is a photovoltaic module frame. In other embodiments, it can be used to test other profiles or materials with a structure similar to that of a photovoltaic module frame.

[0020] The material blocking separation mechanism 1 and the first alignment mechanism 2 are located at the input end of the feeding conveyor line 80. The material blocking separation mechanism 1 includes a blocking module 11 that blocks the profiles 600 on the feeding conveyor line 80 at the first profile position in front of the conveyor; a first sensor 12 that detects whether there are profiles at the first profile position; a second sensor 13 that detects whether there are profiles at the second profile position; a baffle plate 14 located above the junction of the first profile position and the second profile position; and a blocking cylinder 15 that drives the baffle plate 14 to move downward when both the first sensor 12 and the second sensor 13 detect the profile signal. The first profile position is the position at the front of the feeding conveyor line 80 that carries the first profile, and the second profile position is the position in front of the conveyor that carries the second profile. The blocking module 11 includes a blocking cylinder 111 and a blocking plate 112 that is driven by the blocking cylinder 111 to move up and down or rotate. The stop module 11 is installed on the feeding conveyor line 80, and the baffle plate 14 and the baffle cylinder 15 are installed on the frame above the feeding conveyor line 80.

[0021] Two first straightening mechanisms 2 are arranged opposite each other on the left and right sides of the feeding conveyor line 80, respectively, to straighten the two ends of the profile 600, so that the first camera module 20 can accurately take pictures of the ends of the profile, thus improving the accuracy of the picture detection. The first straightening mechanism 2 includes a straightening cylinder 21 and a straightening plate 22 driven by the straightening cylinder 21 to move closer to or away from the end of the profile.

[0022] Two first camera modules 20 are arranged opposite each other on the left and right sides, respectively located at both ends of the profile, to inspect both ends of the profile. Each first camera module 20 includes a first camera 201 located on the side of the profile end, a second camera 202 located above the profile end, and a third camera 203 located below the profile end. By simultaneously using three cameras, defect detection is performed on the outer side of the profile end and the inner side of the base plate, improving detection accuracy. The first camera 201, second camera 202, and third camera 203 are all mounted on a first bracket 204, which is driven by a first motor 205 and moves perpendicular to the conveying direction of the feeding conveyor line 80. The first alignment mechanism 2 is also mounted on the first bracket 204 and moves under the drive of the first motor 205. Integrating the first alignment mechanism 2 and the first camera module 20 onto the same first bracket 204 simplifies the structure and enables the linkage between end alignment and end detection. That is, while the first camera module 20 detects the profile in front, the first alignment mechanism 2 simultaneously performs alignment on the profile behind. The first motor 205 enables the first camera module 20 and the first alignment mechanism 2 to switch between their initial and working positions, and also allows for automatic position adjustment based on the profile length specifications, adapting to profiles 600 of different lengths.

[0023] Several first stop positioning mechanisms 3 are provided and are located in pairs on the feeding conveyor line 80. The structure of the first stop positioning mechanism 3 is the same as that of the stop module 11, and will not be described in detail here.

[0024] The second camera module 30 includes a plurality of fourth cameras 301 arranged in an array. These fourth cameras are mounted above the feeding conveyor line 80 via a support frame 302. The arrangement or layout of the fourth cameras 301 is determined according to the actual situation. In other embodiments, the second camera module 30 is located below or to the side of the feeding conveyor line 80. Therefore, the position of the second camera module 30 and the layout of each fourth camera 301 are determined according to the actual situation and are not limited here.

[0025] A side inspection station is located below the second camera module 30. A second stop positioning mechanism 4 is located at the side inspection station. The feeding conveyor line 80 has several profile bearing positions at the side inspection station, and a third sensor 44 for sensing the profile is located at each profile bearing position. The second stop positioning mechanism 4 includes a first driving member 41, a first support plate 42 driven by the first driving member 41 to move up and down, and several first blocking blocks 43 disposed on the first support plate 42 and corresponding to the profile bearing positions. The first driving member 41 is a motor or a cylinder. The profiles are separated into individual pieces and transported to the side inspection station. When the third sensor 44 on each profile bearing position detects the presence of profile 600, the first drive unit 41 drives the first support plate 42 to move several first blocking blocks 43 upwards and extend between the two profiles. Then the feeding conveyor line 80 moves forward a set distance, so that each profile can achieve the front and rear position correction of a set number of profiles by relying solely on the first blocking blocks 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 detection accuracy of the second camera module 30.

[0026] A pair of flipping mechanisms 5 are respectively clamped at both ends of the profile to perform a flipping action on the profile. The flipping mechanism 5 includes a second driving member 51, a second support plate 52 driven by the second driving member 51 to move along the conveying direction perpendicular to the feeding conveyor line 80, a third driving member 53 disposed on the second support plate 52, a first mounting frame 54 driven by the third 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 that clamps the end of the profile and a fourth driving member 552 that drives the clamping assembly 551 to rotate around a horizontal axis.

[0027] 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 damage to the profile. Preferably, the protective blocks 5513 are made of rubber.

[0028] In this embodiment, five flipping modules 55 are provided. The fourth camera 301 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 angle of the conical shape below the fourth camera 301, profiles at different positions can be flipped at different angles, allowing the fourth camera 301 to clearly capture the surface and groove 601 of the profile 600, thereby improving the inspection accuracy of the profiles. For example, as... Figure 6As shown, the profile 600 located directly below the fourth camera 301 is rotated at angle A so that the groove 601 faces the camera directly. The profiles on both sides are rotated at angles B and C so that the groove 601 faces the camera directly. There is no blind spot within the groove 201, and the area within the groove 601 can be clearly captured. The sizes of angles A, B, and C are related to the placement, rotation direction, and location of the profile 600. The sizes of angles A, B, and C are not limited here and can be set according to the actual situation.

[0029] 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 detected each time can be set according to the actual situation.

[0030] The receiving unit 6 includes a first lifting drive module 61, a first lifting frame 62 driven by the first lifting drive module 61 to move up and down, a fifth drive component 63 disposed on the first lifting frame 62, and a receiving plate 64 driven by the fifth drive component 63 to move closer to or away from the feeding conveyor line 80. The receiving plate 64 is provided with a plurality of pairs of positioning slots 65 for positioning profiles. Each pair of positioning slots 65 is opposite to each other, confining the wire 600 within a pair of positioning slots 65.

[0031] The conveying unit 7 includes a second lifting drive module 71, a second lifting frame 73 driven by the second lifting drive module 71 to perform lifting actions, and a transfer conveyor line 72 disposed on the second lifting frame 73.

[0032] The first lifting frame 62 and the receiving plate 64 are both set between the two belts of the conveying unit 7. The fifth driving component 63 drives the receiving plate 64 to move to the side inspection station to receive the profiles that have completed side inspection, and then moves it to the top of the conveying unit 7. Then the first lifting drive module 61 drives the first lifting frame 62 to lower the receiving plate 64 and put the tested profiles into the transfer conveyor line 72, and then flow into the discharge conveyor line 90.

[0033] Both the receiving unit 6 and the conveying unit 7 are equipped with lifting drive modules, which can lift the receiving plate 64 to transfer the profile to the transfer conveyor line 72, or lift the transfer conveyor line 72 to receive the profile. This provides good flexibility. Alternatively, both can lift simultaneously. For example, when the receiving plate 64 descends, the transfer conveyor line 72 rises to receive the profile, which can improve the efficiency of profile transfer.

[0034] In this embodiment, the feeding conveyor line 80, the transfer conveyor line 72, and the discharging conveyor line 90 are connected in a three-line docking manner, which simplifies the structure and makes the parts small and easy to handle. The feeding conveyor line 80, the transfer conveyor line 72, and the discharging conveyor line 90 are all belt conveyors. In other embodiments, the structure of the conveyor lines can be adjusted according to the actual situation.

[0035] In another embodiment, the feeding conveyor line 80, the transfer conveyor line 72, and the discharging conveyor line 90 can be connected to form an integrated conveying unit, which facilitates the installation and adjustment of the conveyor lines.

[0036] The image processing unit is an industrial control computer, an embedded processor, or a processor of other architectures. The image processing unit receives images captured by the first camera module 20 and the second camera module 30, and then transmits the processed results to the conveying mechanism 9, causing the conveying mechanism 9 to perform a corresponding grasping action. The image processing unit has an embedded visual analysis algorithm configured to perform the following steps: S1. Extract image features; S2. Compare the extracted image features with preset standard features; S3. Determine if a defect exists; S4. Classify the types of defects.

[0037] The specific operation methods of the above steps S1 to S4 are existing technologies, and the methods in the existing technologies can be used, so they will not be described in detail here.

[0038] The conveying mechanism 9 includes a sixth driving member 91, a third support plate 92 driven by the sixth driving member 91 to move back and forth along the conveying direction of the discharge conveyor line 90, a seventh driving member 93 disposed on the third support plate 92, a push rod 94 driven by the seventh driving member 93 to move up and down, a mounting plate 96 disposed at the bottom of the push rod 94, and a plurality of adsorption units 97 disposed at the bottom of the mounting plate 96.

[0039] Due to the relatively long length of the profile, two adsorption units 97 are arranged in the Y direction to ensure adsorption stability. The two adsorption units 97 form a group, adsorbing at different positions along the length of the same profile. In other embodiments, the number of adsorption units 97 in the Y direction can be set according to the actual length of the profile. Several groups of adsorption units 97 are arranged along the X direction to simultaneously adsorb multiple profiles. If multiple defective profiles are detected in the same group, they can be simultaneously adsorbed onto the sorting and palletizing mechanism 8, improving handling efficiency.

[0040] To ensure that the sorting and palletizing mechanism 8 can stack a relatively high number of layers, the push rod 94 is relatively long. The length of the push rod 94 is set according to the actual situation and is not limited here. To ensure the stability of the push rod 94's up and down movement, a first guide rod 98 is fixed on the mounting plate 96. The top end of the first guide rod 98 is movably mounted on the third support plate 92. The first guide rod 98 is movably mounted on the third support plate 92 via a linear bearing 99.

[0041] The sorting and palletizing mechanism 8 includes a second mounting frame 81 and several layers of storage racks 82 spaced vertically on the second mounting frame 81. Each layer of storage rack 82 is equipped with a conveying and storage unit 83. The several layers of conveying and storage units 83 are located directly above the discharge conveyor line 90, so that the adsorption unit 97 can conveniently and quickly place defective profiles onto the conveying and storage units 83. The same layer of conveying and storage units 83 is configured to store defective profiles with the same type of defects. Therefore, the several layers of conveying and storage units 83 can hold defective profiles with various types of defects, including but not limited to: dirt, scratches, cracks, breaks, foreign objects, etc.

[0042] A blocking assembly 85 is installed on the discharge conveyor line 90 below the input end of the conveying and storage unit 83. The blocking assembly 85 includes a second blocking plate 851 that blocks the forward conveying of defective products, a first blocking drive member 852 installed on the discharge conveyor line 90 and driving the second blocking plate 851 to move up and down or rotate, and a fifth sensor 853 installed on the discharge conveyor line 90. The inspected profiles are continuously output through the discharge conveyor line 90. If the image processing unit gives a good product signal, the blocking assembly 85 does not work. If it gives a defective product signal, the blocking assembly 85 starts to work. The first blocking drive member 852 drives the second blocking plate 851 to extend and block the defective profile. The fifth sensor 853 detects the defective profile. The conveying mechanism 9 receives the signal and starts to work. According to the defect type, the conveying mechanism 9 places the defective profile on the corresponding layer of the conveying and storage unit 83.

[0043] The conveying and storage unit 83 includes a second motor 831 mounted on a storage rack 82, a rotating shaft 832 driven by the second motor 831 to rotate horizontally, and conveying support assemblies 833 mounted at both ends of the rotating shaft 832 and perpendicular to its length. The two conveying support assemblies 833 respectively support the two ends of the defective profile. A fourth sensor 835 for sensing the profile is mounted on each conveying support assembly 833. First blocking plates 834 are mounted at both ends of each conveying support assembly 833 to prevent the profile from falling. In other embodiments, a second blocking drive member is also provided to drive the first blocking plates 834 to move up and down or rotate. In this embodiment, the conveying support assembly 833 is a belt conveyor assembly, which not only supports both ends of the defective profile but also conveys the defective profile forward sequentially until the conveying support assembly 833 is full of defective profiles. Furthermore, the conveying and storage unit 83 can be connected to other conveyor lines to conveniently transport defective profiles to a rework station for confirmation and inspection. Furthermore, some defects that can be repaired, such as dirt that can be wiped clean, can be cleaned before being placed on the conveyor support assembly 833. The conveyor support assembly 833 then transports the material in the opposite direction to the end near the handling mechanism 9. The handling mechanism 9 places the repaired and qualified profiles onto the discharge conveyor line 90, and the qualified profiles continue to flow to the next workstation for processing. The input end of each layer's conveyor support assembly 833 extends beyond the outer side of the storage rack 82, so that each layer's conveyor support assembly 833 and storage rack 82 form a clearance space 84 for the adsorption unit 97 to move around, facilitating the adsorption unit 97 to place the profiles onto the conveyor support assembly 833.

[0044] When using the profile inspection device 100 provided in this solution, profiles are continuously fed onto the feeding conveyor line 80, with both ends of the profiles extending beyond the sides of the feeding conveyor line 80 to facilitate clamping by the clamping assembly 551. The material separation mechanism 1 divides the arranged profiles 600 into single pieces for forward feeding. The first stop positioning mechanism 3 blocks the profiles, and the first motor 205 drives the first bracket 204 to approach the ends of the profiles, thereby causing the first alignment mechanism 2 to perform an alignment action on the profiles behind. Simultaneously, the first camera module 20 detects the ends of the profiles in front. After the end detection is completed, the first stop positioning mechanism 3 retracts, and the profiles continue to be fed forward. The second stop positioning mechanism 4 extends to block the profiles. The second driving component 51 drives the second support plate 52 to move several flipping modules 55 closer to the end of the profile 200. The clamping cylinder 5511 drives the clamping plate 5512 to clamp the end of the profile. The third 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 of set angles. The fourth camera 301 takes a picture of the first side of the profile. After taking the picture, several third driving components 552 drive their respective clamping components 551 to rotate the profile 200 by a second set of set angles. The fourth camera 301 takes a picture of the second side of the profile. The profiles are rotated sequentially. The material is photographed until the side of the profile is completely photographed, completing the side inspection of the profile. The fifth drive unit 63 drives the receiving plate 64 to move to the side inspection station. The first lifting drive module 61 drives the first lifting frame 62 to rise to receive the tested profile. The fifth drive unit 63 drives the receiving plate 64 to move directly above the conveying unit 7 and transfer the profile to the transfer conveyor line 72. While the receiving plate 64 is receiving the material, the second stop positioning mechanism 4 has already stopped the next group of profiles. As the receiving plate 64 returns to the transfer conveyor line, the flipping mechanism 5 moves to the second stop positioning mechanism 4 below to clamp the next group of profiles for the next inspection. The profiles on the transfer conveyor line 72 are conveyed. If the image processing unit gives a good product signal on the discharge conveyor line 90, the blocking component 85 and the conveying mechanism 5 do not perform any actions, and the good profile flows into the next workstation for operation via the discharge conveyor line 90; if a defective product signal is given, the blocking component 85 starts to work, the first blocking drive component 852 drives the first blocking plate 851 to extend and block the defective profile, the first sensor 853 detects the defective profile, the conveying mechanism 5 receives the signal, and the conveying mechanism 5 starts to work. According to the defect type, the defective profile is placed on the corresponding layer's conveying storage unit 83, and the conveying storage unit 83 conveys the defective profile forward in sequence until the conveying support component 833 is full of defective profiles.

[0045] 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.
