Description

Technical Field

[0001] This utility model relates to the field of profile testing technology, and in particular to a frame profile straightness testing device and a frame profile pultrusion production line. Background Technology

[0002] The main production method for frame profiles is pultrusion. Raw materials are combed and fed into the pultrusion die, where they are cured and molded under specific pressure and temperature conditions. Powered by a traction machine, the molded frame products are continuously pulled out, and then cut to a fixed length by a cutting machine based on measured length signals. The cut products then undergo straightness testing by an inspection device. Currently, in most publicly available pultrusion production lines, straightness testing is performed manually, resulting in low efficiency and accuracy.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In response to the problems mentioned in the background art, this utility model proposes a frame profile straightness detection device and a frame profile pultrusion production line, which realizes automatic online detection of the straightness of the frame profile, thereby improving detection efficiency and accuracy.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, a straightness detection device for a frame profile is provided. The frame profile includes a first side surface, a second side surface, and a bottom surface. The first side surface and the second side surface are disposed opposite to each other, and the bottom surface is disposed between the first side surface and the second side surface. The straightness detection device includes: a bearing portion configured to bear the frame profile; a side stop assembly having a gap for the frame profile to pass through, the side stop assembly being configured to limit the frame profile from the side; a flipping portion configured to flip the frame profile so that the bottom surface flips from a horizontal state to a vertical state; and a laser distance detection component configured to detect the straightness of the first side surface, the second side surface, and the bottom surface.

[0006] In some embodiments of this application, the side guard assembly includes: The side stop includes two opposingly arranged first side stop members and second side stop members, with the gap formed between the first side stop members and the second side stop members. The side pusher is configured to push the frame profile toward the first side stop so that the first side abuts against the first side stop; the side pusher is also configured to push the frame profile toward the second side stop so that the second side abuts against the second side stop; the side pusher is also configured to push the frame profile toward the first side stop or the second side stop when the bottom surface is in a vertical state so that the bottom surface abuts against the first side stop or the second side stop.

[0007] In some embodiments of this application, the side thrust portion includes: A first sub-side pusher is disposed opposite to the first side stop, and the first sub-side pusher is configured to push the frame profile toward the direction of the first side stop; The second sub-side pusher is disposed opposite to the second side stop, and the second sub-side pusher is configured to push the frame profile toward the direction of the second side stop.

[0008] In some embodiments of this application, a detection conveyor is further included, the detection conveyor being configured to convey the frame profile; the support portion is configured to descend to detach from the frame profile as the frame profile moves along the detection conveyor; the support portion is also configured to rise to lift the frame profile, thereby lifting the frame profile away from the detection conveyor.

[0009] In some embodiments of this application, a blocking portion is also included, which is configured to restrict the advance of the frame profile along the detection conveyor.

[0010] In some embodiments of this application, a buffer conveyor is also included, which is located upstream of the detection conveyor along the conveying direction of the frame profile.

[0011] In some embodiments of this application, the flipping part is disposed below the frame profile. The flipping part includes a lifting drive and a lifting member. The lifting drive is configured such that when the bottom surface is in a horizontal state, the lifting drive drives the lifting member to rise to touch the bottom surface, and the frame profile is flipped 90° to flip the bottom surface to a vertical state.

[0012] In some embodiments of this application, along the length direction of the frame profile, there are two load-bearing portions spaced apart, two sets of side guard assemblies spaced apart, and two flipping portions spaced apart.

[0013] In some embodiments of this application, the support portion is disposed below the frame profile, and the support portion includes a lifting drive and a support member. The lifting drive is configured to drive the support member to move toward or away from the frame profile.

[0014] In some embodiments of this application, a pultrusion production line for frame profiles is also provided, including the aforementioned frame profile straightness detection device.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: The straightness detection device of this application allows the frame profile to be inspected to enter the inspection conveyor from the upstream process. The side baffle assembly automatically completes the side abutment and limit, and the laser assembly automatically performs straightness detection. The entire process requires no manual handling, positioning, or observation, significantly shortening the inspection cycle of a single profile. The inspection process is seamlessly integrated with the pultrusion production line, eliminating the need for offline transfer of profiles, avoiding production line interruptions caused by manual inspection, and increasing production capacity.

[0016] The straightness detection device of this application can perform straightness detection on the first side, second side, and bottom surface of the frame profile, achieving three-sided detection. After the first and second side are detected, the flipping unit automatically flips the profile 90°, turning the originally downward-facing bottom surface into a vertical state. With the side guard assembly's restraint on the bottom surface, the laser assembly can accurately detect the straightness of the bottom surface, ultimately achieving three-sided detection of the frame profile and avoiding product quality risks caused by missed bottom surface inspection.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0027] In some embodiments of this application, a frame profile pultrusion production line is provided. Raw materials are combed and fed to a pultrusion die, where they are cured and molded under specific pressure and temperature conditions. Power provided by a traction machine continuously pulls out the molded frame products, which are then cut to a fixed length by a cutting device based on measured length signals. The cut products are then inspected for straightness and other properties by a testing device. The frame profile 10 can be a photovoltaic frame, bracket, door and window profile, etc.

[0028] In some embodiments of this application, a frame profile straightness detection device is provided, with reference to... Figures 1 to 5 The straightness detection device was structurally improved to achieve automatic online detection of the straightness of the frame profile, thereby improving detection efficiency and accuracy.

[0029] Figure 8 This is a side view of the frame profile 10. The frame profile 10 includes a first side surface 11, a second side surface 12, and a bottom surface 13. The first side surface 11 and the second side surface 12 are disposed opposite to each other, and the bottom surface 13 is disposed between the first side surface 11 and the second side surface 12.

[0030] The testing device includes a testing conveyor table 560, which is configured to convey the frame profile 10. Conveyor wheels 563 are installed on the testing conveyor table 560 to drive the frame profile 10. When the frame profile 10 is conveyed on the testing conveyor table 560, its bottom surface 13 faces downwards and contacts the conveyor wheels 563. After the frame profile 10 is conveyed to its designated position, the conveying stops to allow for subsequent straightness testing. Guide plates 562 are installed on the testing conveyor table 560, arranged sequentially along the conveying direction of the frame profile 10, with guide plates 562 positioned on both the left and right sides of the frame profile 10. The guide plates 562 guide the conveying of the frame profile 10, ensuring that the frame profile 10 accurately reaches the testing position.

[0031] The detection device includes a support portion 510, which is configured to support the frame profile 10, as shown in the reference. Figure 4 , Figure 5 as well as Figure 7 Specifically, when the frame profile 10 is conveyed on the inspection conveyor table 560, the supporting part 510 does not contact the frame profile 10; when the frame profile 10 stops conveying to its position, the supporting part 510 contacts the frame profile 10, causing the frame profile 10 to detach from the inspection conveyor table 560, facilitating subsequent straightness inspection. The supporting part 510 automatically lifts the profile to detach it from the conveyor table, avoiding the influence of the conveyor wheels 563 and the flatness of the conveyor table surface on the profile's posture, thus providing a stable benchmark for inspection.

[0032] The detection device also includes a side baffle assembly 520, which has a gap for the frame profile 10 to pass through. The side baffle assembly 520 is configured to limit the frame profile 10 from the side. Figure 4 and Figure 5 .

[0033] The detection device also includes a flipping part 530, which is configured to flip the frame profile 10 so that the bottom surface 13 flips from a horizontal state to a vertical state, as shown in the figure. Figure 4 , Figure 5 as well as Figure 7 .

[0034] The detection device also includes a laser distance detection component configured to detect the straightness of the first side surface 11, the second side surface 12, and the bottom surface 13.

[0035] The operation process of the detection device is as follows: The frame profile 10 to be inspected is conveyed from the upstream process. The bottom surface 13 of the frame profile 10 faces down. The frame profile 10 passes through the gap of the side baffle assembly 520. After the frame profile 10 moves into place on the inspection conveyor table 560, the bearing part 510 starts to move. The bearing part 510 lifts the frame profile 10 and supports the frame profile 10. The side guard assembly 520 starts to operate. The side guard assembly 520 first abuts and limits the first side 11 of the frame profile 10, and the laser distance detection assembly detects the straight segment of the first side 11. The side guard assembly 520 then abuts against and limits the second side 12 of the frame profile 10, and the laser distance detection assembly detects the straightness of the second side 12; The flipping part 530 starts working, flipping the frame profile 10 by 90°, so that the bottom surface 13 is in a vertical state; The side guard assembly 520 then abuts and limits the bottom surface 13, and the laser distance detection assembly detects the straightness of the bottom surface 13.

[0036] The straightness detection device of this application allows the frame profile 10 to be inspected to enter the inspection conveyor 560 from the upstream process. The side baffle assembly 520 automatically completes the side abutment and limit, and the laser assembly automatically performs straightness detection. The entire process requires no manual handling, positioning, or observation, significantly shortening the inspection cycle of a single profile. The inspection process is seamlessly integrated with the pultrusion production line, eliminating the need for offline transfer of profiles, avoiding production line interruptions caused by manual inspection, and increasing production capacity.

[0037] The straightness detection device of this application can perform straightness detection on the first side 11, the second side 12, and the bottom surface 13 of the frame profile 10, achieving three-sided detection. After the first side 11 and the second side 12 are detected, the flipping part 530 automatically flips the profile 90°, so that the bottom surface 13, which was originally facing down, becomes vertical. With the side guard assembly 520 abutting and limiting the bottom surface 13, the laser assembly can accurately detect the straightness of the bottom surface 13, thus achieving three-sided detection of the frame profile 10 and avoiding product quality risks caused by missed detection of the bottom surface 13.

[0038] In some embodiments of this application, reference is made to Figure 4 Along the length of the frame profile 10, there are two load-bearing parts 510 spaced apart, two sets of side guard assemblies 520 spaced apart, and two flipping parts 530 spaced apart.

[0039] Two support units 510 are evenly spaced along the length of the frame profile 10. When the frame profile 10 is conveyed to its position and stops by the detection conveyor table 560, the two support units 510 simultaneously receive control signals and execute an upward lifting action. The two support units 510 can form a two-point stable support for the long profile, providing a horizontal reference for the bottom surface and preventing tilting. The stable two-point support can prevent the profile from shifting position when clamped by the subsequent flipping unit 530, ensuring that the flipping unit 530 can accurately align with both sides of the profile, laying the foundation for the smoothness of the flipping action.

[0040] Two sets of spaced side stop components 520 can achieve segmented limiting of the entire length of the profile, ensuring that each detection segment in the length direction of the profile is on the same reference plane, and that the full-length data scanned by the laser component is true and valid.

[0041] In some embodiments of this application, reference is made to Figure 5 The side guard assembly 520 includes a side guard portion 521 and a side push portion 522.

[0042] The side stop 521 includes two opposing first side stop members 5211 and second side stop members 5212, with a gap formed between the first side stop members 5211 and the second side stop members 5212 for the frame profile 10 to pass through. For example, the first side stop members 5211 and the second side stop members 5212 are rollers.

[0043] The side pusher 522 is configured to push the frame profile 10 toward the first side stop 5211 so that the first side surface 11 abuts against the first side stop 5211. The side pusher 522 is also configured to push the frame profile 10 toward the second side stop 5212 so that the second side surface 12 abuts against the second side stop 5212. The side pusher 522 is also configured to push the frame profile 10 toward the first side stop 5211 or the second side stop 5212 when the bottom surface 13 is in a vertical state so that the bottom surface 13 abuts against the first side stop 5211 or the second side stop 5212.

[0044] The first side stop 5211 and the second side stop 5212 are symmetrically arranged along the profile conveying path. During the profile conveying stage, the profile passes through the gap formed by the two, and the rollers rotate synchronously with the profile movement to avoid sliding friction with the side of the profile. The reserved gap width design ensures that there is no jamming during profile conveying and also allows sufficient stroke for the adjustment action of the side push part 522.

[0045] By adjusting the thrust stroke of the side pusher 522, it can be adapted to profiles with different widths of bottom surface 13 without replacing the side baffle, thus improving the compatibility of the device with products of various specifications.

[0046] In some embodiments of this application, reference is made to Figure 5 The side-pushing portion 522 includes a first sub-side-pushing portion 5221 and a second sub-side-pushing portion 5222. The first sub-side-pushing portion 5221 is disposed opposite to the first side stop 5211, and is configured to push the frame profile 10 toward the first side stop 5211. The second sub-side-pushing portion 5222 is disposed opposite to the second side stop 5212, and is configured to push the frame profile 10 toward the second side stop 5212.

[0047] The first sub-side push part 5221 and the second sub-side push part 5222 have the same structure, and each includes a side push drive member 5223 and a side push member 5224 respectively. The side push drive member 5223 drives the side push member 5224 to move in the horizontal direction toward or away from the frame profile 10.

[0048] The first sub-side push part 5221 is positioned opposite to the first side stop 5211, and the second sub-side push part 5222 is positioned opposite to the second side stop 5212, to prevent the side push cylinder from affecting the straightness of the frame profile 10.

[0049] The first sub-side pusher 5221 and the second sub-side pusher 5222 adopt an independent driving and non-interfering operation mode. When detecting a certain side, only the corresponding sub-side pusher 522 needs to be activated, while the other sub-side pusher 522 remains in its initial position, simplifying the operation process and ensuring reliable pushing effect on the profile.

[0050] In some embodiments of this application, reference is made to Figure 4 The support portion 510 is disposed below the frame profile 10. The support portion 510 is configured to descend to detach from the frame profile 10 as the frame profile 10 moves along the inspection conveyor table 560. The support portion 510 is also configured to rise to lift the frame profile 10, thereby lifting the frame profile 10 away from the inspection conveyor table 560.

[0051] The bearing unit 510 adopts a design with a bottom setting and lifting function. It can be separated to avoid interference during transportation and lifted to set a reference during inspection. It works in conjunction with the side guard assembly 520 and the flipping unit 530 to realize automatic detection of the straightness of the frame profile 10.

[0052] In some embodiments of this application, reference is made to Figure 7The support unit 510 includes a lifting drive 511 and a support member 512. The lifting drive 511 is configured to drive the support member 512 to move toward or away from the frame profile 10. For example, the lifting drive 511 is a cylinder. The lifting drive 511 is fixedly mounted on the frame of the inspection conveyor table 560.

[0053] In some embodiments of this application, reference is made to Figure 2 , Figures 4 to 6 The straightness detection device also includes a blocking part 540, which is configured to restrict the advance of the frame profile 10 along the detection conveyor table 560.

[0054] The blocking part 540 includes a blocking drive 541 and a blocking plate 542. For example, the blocking drive 541 is a cylinder. The blocking drive 541 is fixedly mounted on the frame of the inspection conveyor table 560. The blocking drive 541 drives the blocking plate 542 to move upward or downward. After the blocking plate 542 moves upward, it is located at the front end of the frame profile 10, stopping the frame profile 10. After the three sides of the frame profile 10 are inspected, the blocking plate 542 descends, waiting for the next frame profile 10 to arrive.

[0055] In some embodiments of this application, a positioning detection switch 561 is provided on the detection conveyor table 560. After the positioning detection switch 561 detects the frame profile 10, the frame profile 10 is conveyed to the positioning position and then it abuts against the baffle plate 542. Then the carrier 512 rises and lifts the frame profile 10 away from the detection conveyor table 560.

[0056] In some embodiments of this application, reference is made to Figure 5 and Figure 7 The flipping part 530 is disposed below the frame profile 10. The flipping part 530 includes a lifting drive 531 and a lifting member 532. The lifting drive 531 is configured to drive the lifting member 532 to rise and touch the bottom surface 13 when the bottom surface 13 is in a horizontal state, causing the frame profile 10 to flip 90° so that the bottom surface 13 flips to a vertical state. For example, the lifting drive 511 is a cylinder. The lifting drive 511 is fixedly mounted on the frame of the inspection conveyor table 560. The top of the lifting member 532 has a pointed structure to reduce the contact area with the frame profile 10.

[0057] In some embodiments of this application, the flipping part 530 and the supporting part 510 are integrated on the same mounting bracket, resulting in a compact structure.

[0058] In some embodiments of this application, reference is made to Figure 1The straightness detection device also includes a buffer conveyor 570, which is located upstream of the detection conveyor 560 along the conveying direction of the frame profile 10.

[0059] By setting up a buffer conveyor 570 to replace the rigid connection of the traditional testing conveyor 560 directly to the pultrusion line, the technical problems of mismatch between the continuous output of the pultrusion line and the intermittent testing rhythm of the testing station, the accumulation and jamming of profiles, and the forced shutdown of the pultrusion line in the traditional design are solved.

[0060] In some embodiments of this application, reference is made to Figure 1 and Figure 3 The straightness detection device also includes a gantry robot assembly 580 and a material frame 590.

[0061] The truss robot assembly 580 includes two spaced-apart robot arms 581, which grip both ends of the frame profile 10. The robot arms 581 move horizontally and vertically under the action of a drive mechanism.

[0062] The system determines whether the frame profile 10 is a qualified product based on the detection data of the laser distance detection component. If it is a defective product, the gantry robot component 580 grabs the frame profile 10 and puts it into the material box 590. If it is a qualified product, the blocking component descends and the frame profile 10 is transferred to the next process.

[0063] In some embodiments of this application, the laser distance detection component includes a first laser distance sensor 551 and a second laser distance sensor 552, which are respectively disposed on both sides of the frame profile 10. The first laser distance sensor 551 is located on the side where the first side stop 5211 is located, and the second laser distance sensor 552 is located on the side where the second side stop 5212 is located.

[0064] The operation process of the straightness testing device is as follows: The straightness zero points of the two first side stops 5211 and the first laser distance sensor 551 are calibrated, and the straightness zero points of the two second side stops 5212 and the second laser distance sensor 552 are calibrated. The frame profile 10 is conveyed in by the buffer conveyor 570. The bottom surface 13 of the frame profile 10 faces downward, the first side 11 faces the first side stop 5211, the second side 12 faces the second side stop 5212, and the blocking drive 541 drives the blocking member to rise, so that the blocking member is in the extended blocking state. When the position detection switch 561 detects the frame profile 10, the lifting drive component 511 drives the support component 512 to rise. The front and rear support components 512 rise and lift the frame profile 10, so that the frame profile 10 is in a two-point support state. The second side pusher 5222 is pushed out, pushing the frame profile 10 toward the direction of the first side stop 5211, until the first side 11 of the frame profile 10 abuts against the first side stop 5211. Then the first laser distance sensor 551 detects the straightness of the first side 11; The second sub-side pusher 5222 retracts back to its original position, and the first sub-side pusher 5221 extends out, pushing the frame profile 10 toward the direction close to the second side stop 5212, until the second side 12 of the frame profile 10 abuts against the second side stop 5212. Then the second laser distance sensor 552 detects the straightness of the second side 12; The first side push part 5221 retracts to its original position, the flipping part 530 is activated, the lifting drive 531 drives the lifting part 532 to rise, the contact position of the lifting part 532 with the frame profile 10 is close to the first side 11, as the lifting part 532 continues to rise, the frame profile 10 is flipped 90°, the second side 12 faces down, and the bottom surface 13 faces the first side stop 5211; The lifting member 532 descends, and the second sub-side pusher 5222 extends, pushing the frame profile 10 toward the first side stop 5211, until the bottom surface 13 of the frame profile 10 abuts against the first side stop 5211; Then the first laser distance sensor 551 detects the straightness of the bottom surface 13; The second side push part 5222 retracts and returns to its original position. Based on the straightness detection data, the system determines whether the frame profile 10 is a qualified product or a defective product. If it is a defective product, the truss robot arm assembly 580 grabs the frame profile 10 and puts it into the material box 590. If it is a qualified product, the blocking part descends and the frame profile 10 is transferred to the next process.

[0066] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
