Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component detection, and in particular to a comprehensive detection platform for photovoltaic frame detection and an automatic detection line thereof. Background Art

[0002] With the increasing exploitation of traditional energy sources such as oil and coal, and based on the awareness of energy crisis, humans pay more and more attention to the research and development of new energy technologies. Photovoltaic technology is based on the principle of photoelectric effect, and its energy mainly comes from sunlight. It is an extremely clean energy source, and has gradually replaced other new energy technologies and become the leader. Due to the rapid development of the photovoltaic industry, the production efficiency and product quality of photovoltaic modules have attracted more and more attention from major manufacturers. Among them, the photovoltaic frame is an important component of photovoltaic modules, and its dimensional accuracy and appearance quality will directly affect the overall life and performance of photovoltaic modules.

[0003] The existing photovoltaic frame detection is mostly carried out by manual detection. However, manual detection is inefficient on the one hand, and with the increase of production capacity, the number of false detections and missed detections also gradually increases, resulting in low efficiency and high full inspection costs. In addition, the photovoltaic frame detection devices provided by the existing technology are often relatively simple, with disadvantages such as long process cycle and high detection cost. Utility Model Content

[0004] The utility model aims at the technical problems of single manual detection and single automatic detection in the prior art, and provides a comprehensive detection platform for photovoltaic frame detection, which has at least the advantages of high detection efficiency, wide detection coverage, and low equipment cost.

[0005] First aspect

[0006] The utility model provides a comprehensive detection platform for photovoltaic frame detection, including:

[0007] A base to provide structural support;

[0008] A detection transmission line is arranged on the base and has a transmission function;

[0009] A visual inspection station, a length inspection station and a bending and torsion inspection station are arranged along the transmission path of the inspection transmission line;

[0010] The visual inspection station includes a first lifting mechanism, a flipping mechanism and a visual inspection station. The first lifting mechanism and the flipping mechanism are arranged on both sides of the inspection transmission line. The visual inspection station is arranged relative to the transmission line.

[0011] The length detection station includes a displacement sensor and a second jacking mechanism;

[0012] The bending and torsion detection station comprises a contact sensor and a third lifting mechanism.

[0013] Specifically, one of the main concepts of the utility model is to integrate visual inspection, length inspection and bending and torsion inspection into one inspection platform to improve the comprehensiveness of inspection and thus improve the inspection efficiency. At the same time, the main concept of the utility model is to set a flipping mechanism at the visual inspection station, and with the cooperation of the lifting mechanism, the photovoltaic frame is flipped at multiple angles, thereby improving the comprehensiveness and reliability of visual inspection. In addition, the main concept of the utility model is to set a second lifting mechanism and a third lifting mechanism at the length inspection station and the bending and torsion inspection mechanism, so that the inspection of the photovoltaic frame is in a lifting state, eliminating the transportation error of the inspection transmission line, and making the inspection process smoother and more accurate.

[0014] Furthermore, the length detection station is adjacent to the bending and torsion detection station, and the second lifting mechanism and the third lifting mechanism are an integrated part.

[0015] Specifically, based on the similarity between the length detection station and the bending and torsion detection station, the utility model sets the two stations adjacent to each other, thereby simplifying the second jacking mechanism and the third jacking mechanism and reducing the complexity of the comprehensive detection platform.

[0016] Optionally, the visual inspection station is provided with at least two groups to balance the inspection time of the visual inspection station with the inspection time of the length inspection station and the bending and torsion inspection station.

[0017] Specifically, another concept of the present invention is to balance the detection time of the comprehensive detection platform by setting up multiple groups of the visual detection stations to improve its detection efficiency. It is worth noting that since the visual detection station needs to flip and photograph the photovoltaic frame at multiple angles, its detection time is relatively long, while the length detection station and the bending and torsion detection station only need to use different sensors to detect the photovoltaic frame, and the detection time is relatively short. If the visual detection station, length detection station and bending and torsion detection station described in the comprehensive detection platform are arranged one by one, the detection time of the visual detection station will inevitably affect the detection time of the length detection station and the bending and torsion detection station. Therefore, the present invention sets at least two groups of the visual detection stations in the comprehensive detection platform for alternate detection of the photovoltaic frame to balance the detection time of the length detection station and the bending and torsion detection station, thereby reducing equipment costs and improving detection efficiency.

[0018] In some embodiments, the first lifting mechanism comprises: a driving mechanism and a lifting table disposed on the driving mechanism;

[0019] The flipping mechanism comprises a clamping assembly, a telescopic arm and a rotating motor. The rotating motor is used to drive the rotation of the telescopic arm. The clamping assembly is arranged at the open end of the telescopic arm.

[0020] Specifically, when the photovoltaic frame flows to the visual inspection station, the first lifting mechanism lifts the photovoltaic frame through its lifting table, and then the flipping mechanism controls the clamping assembly to clamp the photovoltaic frame through its telescopic arm, and then the flipping mechanism adjusts the orientation angle of the photovoltaic frame through the rotating motor, so that the visual inspection station above can take pictures of the photovoltaic frame at multiple angles, so as to improve the comprehensiveness of photovoltaic frame detection and reduce the missed detection rate of automatic photovoltaic frame detection.

[0021] Furthermore, the flipping mechanism includes a shock absorber.

[0022] Specifically, the shock absorber is used to reduce shock during the flipping process of the photovoltaic frame to prevent it from shaking and displacement, thereby affecting the detection effect of the visual detection position.

[0023] Optionally, the axis of the telescopic arm coincides with the center line of the lifting table.

[0024] Specifically, through the above arrangement, the flip mechanism can clamp the photovoltaic component through its clamping assembly at the center line of the photovoltaic frame, thereby improving the rotational stability of the flip mechanism and avoiding the phenomenon of material falling off of the photovoltaic frame.

[0025] Optionally, a buffer station is provided before the visual inspection station, the length inspection station and the bending and torsion inspection station;

[0026] The buffer station comprises a centering mechanism, and the centering mechanism is arranged on both sides of the detection transmission line.

[0027] Specifically, the centering mechanism is used for centering before photovoltaic frame detection to ensure the identity during photovoltaic frame detection.

[0028] Furthermore, a material blocking assembly is provided before the buffer station, and the material blocking assembly is provided on both sides of the detection transmission line;

[0029] The material blocking assembly includes a telescopic assembly, a material blocking block and a proximity sensor or a collision sensor;

[0030] The material stopper is arranged on the telescopic assembly, and the proximity sensor or the collision sensor is arranged on the material stopper.

[0031] Specifically, another concept of the utility model is to count the delivery of photovoltaic frames and control the flow into the detection transmission line through the material blocking assembly to ensure the orderly operation of the comprehensive detection platform and improve its reliability.

[0032] Second aspect

[0033] The utility model provides an automatic detection line for photovoltaic frame detection, including the comprehensive detection platform for photovoltaic frame detection provided by any embodiment of the first aspect, including:

[0034] A material input line and a material output line are arranged at the input end and the output end of the detection transmission line.

[0035] Specifically, the utility model realizes the streamlined operation of photovoltaic frame detection by setting up a material input line and a material output line.

[0036] Furthermore, the material output line includes a sorting line, and the sorting line is used to divert unqualified products to improve the degree of automation of photovoltaic frame detection.

[0037] In summary, the utility model provides a comprehensive detection platform for photovoltaic frame detection and an automatic detection line thereof, which has at least the following advantages:

[0038] 1. The utility model integrates visual inspection, length inspection and bending and torsion inspection into one inspection platform to improve the comprehensiveness of inspection and thus improve the inspection efficiency. At the same time, the utility model also sets a flipping mechanism at the visual inspection station, and with the cooperation of the lifting mechanism, the photovoltaic frame is flipped at multiple angles, thereby improving the comprehensiveness and reliability of visual inspection. In addition, the utility model also sets a second lifting mechanism and a third lifting mechanism at the length inspection station and the bending and torsion inspection mechanism, so that the inspection of the photovoltaic frame is in a lifting state, eliminating the transportation error of the inspection transmission line, and making the inspection process smoother and more accurate;

[0039] 2. The utility model balances the detection time of the comprehensive detection platform by setting up multiple groups of visual detection stations to improve its detection efficiency;

[0040] 3.

[0041] 4. The utility model improves the rotation stability of the flip mechanism by clamping the flip mechanism on the center line of the photovoltaic frame, thus avoiding the phenomenon of material falling off of the photovoltaic frame;

[0042] 5.

[0051] The following is combined with Figures 1 to 6 , the utility model is described in detail.

[0052] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0053] The main idea of ​​the utility model is to integrate the visual inspection station, the length inspection station and the bending and torsion inspection station into one, so as to form a comprehensive inspection platform for photovoltaic frame inspection, thereby improving the inspection efficiency and comprehensiveness of the comprehensive inspection platform.

[0054] For further information, see Figure 1 Shown is a structural schematic diagram of a comprehensive detection platform for photovoltaic frame detection provided by the utility model.

[0055] Specifically, the direction indicated by the arrow in the figure is the moving direction of the detection transmission line 2. At the same time, the comprehensive detection platform includes a base 1, and the base 1 includes a detection table 11 and a frame 12. The detection table 11 is used for installing components for detection such as the detection transmission line 2, the visual detection station 3, the length detection station 4 and the bending and torsion detection station 5, and the frame 12 is an installation frame of an I-beam frame, which is used to provide structural support and installation support.

[0056] Furthermore, the detection transmission line 2 is a belt transmission structure, see Figure 6 As shown ( Figure 6 The embodiment of the utility model provides Figure 1 (see enlarged view at point E of FIG. 1 ), which includes a transmission belt, a driving mechanism and other mechanisms for realizing the transmission of the photovoltaic frame placed thereon.

[0057] Furthermore, along the transmission path (direction indicated by the arrow) of the detection transmission line 2, the comprehensive detection platform is provided with a visual detection station 3, a length detection station 4 and a bending and torsion detection station 5.

[0058] The visual inspection station 3 includes a first lifting mechanism 31, a flipping mechanism 32 and a visual inspection station 33. The structure of the first lifting mechanism 31 can be seen Figure 5 As shown ( Figure 5 The embodiment of the utility model provides Figure 1 The turning mechanism 32 (see FIG. Figure 2 As shown, Figure 2 The embodiment of the utility model provides Figure 1 The enlarged view at point A of the figure) includes a clamping assembly 321, a telescopic arm 322 and a rotating motor (not shown in the figure). The rotating motor is used to drive the rotation of the telescopic arm 322. The clamping assembly 321 is arranged at the open end of the telescopic arm 322. The visual inspection station 33 is arranged above the detection transmission line 2, and is used to detect the photovoltaic frame thereon. It is worth noting that when the photovoltaic frame is transmitted to the visual inspection station 3 via the detection transmission line 2, the first lifting mechanism 31 supports it to make it separate from the detection transmission line 2, and then the flipping mechanism 32 flips it at multiple angles. During the flipping process of the flipping mechanism 32, the visual inspection station 3 shoots the photovoltaic frame at multiple angles, thereby realizing a comprehensive inspection of the appearance of the photovoltaic frame.

[0059] The length detection station 4 includes a displacement sensor 42 (see Figure 4 The utility model embodiment provides Figure 1 C) and the second lifting mechanism 41 (see Figure 5 As shown), the bending and torsion detection station 5 includes a contact sensor 52 (see Figure 4 As shown) and the third lifting mechanism 51 (see Figure 5 shown).

[0060] Optionally, the structures of the second lifting structure and the third lifting mechanism 51 are similar to those of the first lifting mechanism 31, and are also used to lift the photovoltaic frame from the detection transmission line 2, so that it is temporarily suspended and detached from the detection transmission line 2, and then the displacement sensor 42 and the contact sensor 52 respectively detect the length and bending torsion of the photovoltaic frame.

[0061] Optionally, the length detection station 4 is adjacent to the bending and torsion detection station 5, and the second lifting mechanism 41 and the third lifting mechanism 51 are integrated, thereby simplifying the structure of the comprehensive detection platform.

[0062] Optionally, the visual inspection station 3 includes a light source, and the light source is arranged around the visual inspection station 33 to provide supplementary light for the visual inspection station 33 .

[0063] Optionally, the visual inspection station 33 is provided with at least two groups to balance the inspection time of the visual inspection station 3 with the inspection time of the length inspection station 4 and the bending and torsion inspection station 5 .

[0064] Specifically, since the visual inspection station 33 needs to flip the photovoltaic frame at multiple angles, the inspection time is relatively long, which easily causes the length inspection station 4 and the bending and torsion inspection station 5 to wait. In order to improve the inspection efficiency of the comprehensive inspection platform, multiple groups of visual inspection stations 3 are provided.

[0065] Assuming that the detection time of the visual inspection station 3 is greater than or equal to twice the detection time of the length detection station 4 and the bending and torsion detection station 5, but less than three times, the visual inspection station 3 is set in two groups, otherwise different multiples are set according to the time ratio (if it is greater than three times and less than four times, then take three, and so on. Generally speaking, two times can meet the use requirements). At this time, the stations of the comprehensive detection platform are set as two visual inspection stations 3, one length detection station 4, and one bending and torsion detection station 5. When the photovoltaic frame flows into the detection platform, the visual inspection station 3 close to the length detection station 4 and the bending and torsion detection station 5 is first used for appearance inspection, and then the other visual inspection station 3 is used to synchronously inspect the other photovoltaic frame, so that the simultaneous inspection of the two photovoltaic frames can be met, thereby improving the inspection efficiency of the comprehensive detection platform.

[0066] Optionally, the flip mechanism 32 includes a shock absorber 323 (see Figure 4 shown).

[0067] Optionally, the axis of the telescopic arm 322 coincides with the center line of the lifting table. The above arrangement enables the flipping mechanism 32 to clamp the photovoltaic component through its clamping assembly 321 at the center line of the photovoltaic frame, thereby improving the rotational stability of the flipping mechanism 32 and avoiding the phenomenon of material falling off the photovoltaic frame.

[0068] Optionally, a buffer station 6 is provided before the visual inspection station 3, the length inspection station 4 and the bending and torsion inspection station 5; the buffer station 6 includes a centering mechanism 61 (see Figure 2 As shown), the centering mechanism 61 is arranged on both sides of the detection transmission line 2. Specifically, the centering mechanism 61 is used for centering before photovoltaic frame detection to ensure the identity of photovoltaic frame detection.

[0069] Furthermore, a material blocking assembly 62 is provided before the buffer station 6 (see Figure 3 The utility model embodiment provides Figure 1 The material blocking assembly 62 is arranged on both sides of the detection transmission line 2;

[0070] Specifically, the material blocking assembly 62 includes a telescopic assembly 621, a material blocking block 622, and a proximity sensor 623 or a collision sensor;

[0071] The stopper block 622 is disposed on the telescopic assembly 621 , and the proximity sensor 623 or the collision sensor is disposed on the stopper block 622 .

[0072] Specifically, another concept of the present invention is to count the delivery of the photovoltaic frame and control the flow into the detection transmission line 2 through the material blocking assembly 62, so as to ensure the orderly operation of the comprehensive detection platform and improve its reliability.

[0073] It is worth mentioning that the utility model also provides an automatic detection line for photovoltaic frame detection, including: a material input line 7 and a material output line 8 arranged at the input end and the output end of the detection transmission line 2.

[0074] Further, the material output line 8 includes a sorting line (see Figure 6 As shown), the sorting line is used to divert unqualified products to improve the degree of automation of photovoltaic frame detection.

[0075] The utility model is described in detail above. The utility model uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
