Description

Technical Field

[0001] The invention relates to the technical field of plate detection, and in particular to a flatness detection device for curtain wall aluminum plate composite plates. Background Art

[0002] Aluminum panels and composite panels for curtain walls need to go through multiple processes during the production process, such as cutting, marking and cornering, bending, arc rolling, argon arc welding, grinding, polishing, etc., to ensure product quality, especially the detection of the surface flatness of the panel. If the surface flatness of the aluminum panel does not meet the requirements, it will lead to difficulties and failures in the assembly, processing, painting and other processes.

[0003] At present, flatness detection machines are commonly used in sheet metal processing production lines to detect the flatness of sheets, that is, the sheets will enter the flatness detection machine through a conveyor belt or other automatic conveying device; then the flatness detection machine uses laser projection or optical scanning technology through the machine head to scan the surface of the conveyed sheet metal; thereby obtaining accurate three-dimensional data of the sheet metal surface; finally, the flatness detection machine calculates and analyzes the collected data; and evaluates the flatness of the sheet metal. However, the production cost of this equipment is relatively high, and during the conveying process of the sheet metal, the upper surface of the sheet metal faces upward, and only one-side scanning can be performed, which not only increases the labor intensity of the staff, but also introduces additional human errors, thereby affecting the precision and accuracy of the lower surface measurement.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 14 :

[0035] A flatness detection device for curtain wall aluminum composite plate comprises a feeding platform 1, and a mounting bracket 11 and a conveying unit 12 installed in the middle of the feeding platform 1, a flatness detection unit 2 is installed on the mounting bracket 11, and the conveying unit 12 conveys the plate to and fro through the flatness detection unit 2; the flatness detection unit 2 comprises a mounting frame 21 slidably mounted on the mounting bracket 11, and two parallel mounting rods 211 are arranged on the mounting frame 21, and the mounting rods 211 are respectively located on the upper and lower sides of the feeding platform 1 , each mounting rod 211 is rotatably connected to a plurality of force arms 22, the force arms 22 are evenly spaced along the axis of the mounting rod 211, and a laminating wheel 23 is rotatably mounted on one end of the force arm 22 away from the mounting rod 211, and the laminating wheel 23 is laminating the upper and lower sides of the plate passing through the flatness detection unit 2; a waist-shaped hole 221 extending along the length direction of the force arm 22 is provided in the middle of the force arm 22, and the same number of guide holes 212 as the force arms 22 are provided on the upper and lower sides of the mounting frame 21, and a lifting rod 24 (such as Figure 4 and Figure 5As shown), a connecting head 241 is arranged at the bottom of the lifting rod 24, and a horizontal connecting rod 242 is arranged on the connecting head 241, and the connecting rod 242 is inserted into the waist-shaped hole 221 of the force arm 22, and a first spring 243 is sleeved on the lifting rod 24, and the first spring 243 elastically connects the connecting head 241 and the mounting frame 21, and the elastic force of the first spring 243 makes the bonding wheel 23 bond to the surface of the plate, and a horizontal plate 25 is arranged at one end of the lifting rod 24 away from the connecting head 241, and a first sensor 26 for detecting the lifting state of the horizontal plate 25 is arranged on the mounting frame 21; a translation unit 3 is also arranged on the mounting bracket 11, and the translation unit 3 drives the mounting frame 21 of the flatness detection unit 2 to translate along the axial direction of the mounting rod 211 when the conveying direction of the conveying unit 12 changes, so as to change the detection position of the bonding wheel 23.

[0036] When the flatness detection device in the present application is in use, the staff places the plate to be tested on the feeding platform 1, and the conveying unit 12 conveys the plate from the positive direction through the flatness detection unit 2 on the mounting bracket 11. The mounting frame 21 of the flatness detection unit 2 is located on the upper and lower sides of the feeding platform 1 and is provided with a plurality of lifting rods 24. The elastic force of the first spring 243 on the lifting rod 24 causes the lifting rod 24 to move toward the feeding platform 1. The connecting head 241 of each lifting rod 24 is inserted into the waist-shaped hole 221 of the force arm 22 through the connecting rod 242. One end of the force arm 22 is rotatably mounted on the mounting frame 21 located on the upper and lower sides of the feeding platform 1. The laminating wheels 23 are arranged on the mounting rod 211 on the side thereof, so the elastic force of the first spring 243 can also make the end of the force arm 22 on which the laminating wheel 23 is installed move toward the feeding platform 1, so that the two opposite laminating wheels 23 are laminating at the upper surface of the feeding platform 1, and the feeding platform 1 can be provided with holes for avoiding the laminating wheels 23. When the plate passes through the flatness detection unit 2, the plate pushes the two laminating wheels 23 apart, and the laminating wheels 23 are respectively laminating on the upper and lower sides of the plate. Since the force arm 22 and the laminating wheels 23 are evenly spaced along the axial direction of the mounting rod 211, the laminating wheels 23 can be laminating on the upper and lower sides of the plate of any width passing through the flatness detection unit 2, and At the same time, the flatness of the upper and lower sides of the plate is detected to improve the efficiency of the detection; when there are uneven parts on the upper and lower sides of the plate, the laminating wheel 23 can move up or down to fit the part and can drive the power arm 22 to rotate around the axis of the mounting rod 211. The rotation of the force arm 22 drives the connecting rod 242 to move in the waist-shaped hole 221, thereby driving the lifting rod 24 to move in the vertical direction. The lifting and lowering of the horizontal plate 25 at the top of the lifting rod 24 is detected by the first sensor 26, and a signal can be sent to the data processor, indicating that there is an uneven part of the plate at this position; there is a gap between the laminating wheels 23 in this embodiment, in order to ensure that The flatness detection is performed on the part where the laminating wheel 23 does not contact the plate. In this embodiment, a translation unit 3 is also provided on the mounting bracket 11. When the plate passes through the flatness detection unit 2 along the square, the conveying unit 12 can drive the plate to pass through the flatness detection unit 2 again in the opposite direction. At this time, the translation unit 3 automatically drives the mounting frame 21 of the flatness detection unit 2 to translate along the axial direction of the mounting rod 211, thereby changing the contact position between the laminating wheel 23 and the plate. When the plate passes through the flatness detection unit 2 in the opposite direction, a second detection is performed on the plate to ensure the comprehensiveness of the flatness detection. The staff can take the plate away after the plate is reset.

[0037] In order to solve the problem of how to enable the first sensor 26 to detect the movement of the horizontal plate 25 when a plate of any thickness passes through the flatness detection unit 2, the following features are specifically set:

[0038] The first sensor 26 is fixedly installed in the adjustment box 261 (such as Fig. 9As shown in the figure, the adjustment box 261 is slidably mounted on both ends of the horizontal bonding plate 262, the working end of the first sensor 26 is located on the side of the bonding plate 262 close to the horizontal plate 25, and the two ends of the bonding plate 262 are provided with hanging ears 263. The upper and lower sides of the mounting frame 21 are provided with vertically extending first guide rods 213. The bonding plate 262 is slidably mounted on the first guide rod 213 through the hanging ears 263. The first guide rod 213 is sleeved with a second spring 214. The elastic force of the second spring 214 makes the bonding plate 262 fit the horizontal plate 25.

[0039] Taking the bonding wheel 23 on the upper side of the feeding platform 1 as an example, after the bonding wheel 23 in this embodiment is lifted up by a plate of any thickness, the lifting rod 24 compresses the first spring 243 to lift the position of the horizontal plate 25. At this time, the horizontal plate 25 linked to the bonding wheels 23 that are in contact with the plate is higher than the position of the horizontal plate 25 linked to the bonding wheels 23 that are not in contact with the plate. The bonding plate 262 moves down and is bonded to the horizontal plate 25 and then restricted from moving. At this time, the first sensors 26 at both ends of the bonding plate 262 are located on the lower side of the horizontal plate 25. The first sensor 26 in this embodiment can be a laser sensor and a receiver. When a certain part on the upper side of the plate bulges upward, the bonding wheel 23 that contacts this position drives the power arm 22 to flip upward. At this time, the lifting rod 24 connected to the power arm 22 moves upward, and the horizontal plate 25 at the top of the lifting rod 24 moves upward to lift the bonding plate 262. At this time, the position of the first sensor 26 is raised, and the laser emitted by the first sensor 26 is blocked by the horizontal plate 25 that remains unchanged in other positions. A signal is sent to indicate that there is unevenness at that position, and data marking is performed in cooperation with the data processing module, or in cooperation with an actual marking device (any existing technology can be used, no further elaboration is made here, and it is not shown in the figure) to mark on the plate, and subsequent staff can straighten the horizontal direction of the marked point; when a certain part on the upper side of the plate is recessed downward, the bonding wheel 23 contacting the position drives the power arm 22 to flip downward, and at this time, the lifting rod 24 connected to the power arm 22 moves downward, and the horizontal plate 25 on the top of the lifting rod 24 moves downward. Since the position of the bonding plate 262 remains unchanged, the downwardly moved horizontal plate 25 blocks the laser emitted by the first sensor 26, so the first sensor 26 can send a signal indicating that there is unevenness at that position. The first sensor 26 in this embodiment is installed on the bonding plate 262, and the bonding plate 262 maintains adaptive bonding with the horizontal plate 25 under the elastic force of the second spring 214, so that plates of any thickness can be detected without manual adjustment.

[0040] In order to solve the problem of how to ensure the detection accuracy of the first sensor 26, the following features are specifically set:

[0041] Both ends of the laminating plate 262 are provided with vertically extending sliding grooves 264, and the adjusting box 261 is slidably installed in the sliding grooves 264. One side of the sliding groove 264 is provided with a threaded hole 265 (such as Fig.13 As shown in the figure), a locking bolt 266 is screwed in the threaded hole 265, and the locking bolt 266 fits against one side of the adjustment box 261 to lock the position of the adjustment box 261.

[0042] In this embodiment, the first sensor 26 is installed in the adjustment box 261. The adjustment box 261 slides in the sliding grooves 264 at both ends of the bonding plate 262 to change the straight-line distance between the working end of the first sensor 26 and the bottom of the horizontal plate 25, thereby controlling the detection accuracy of the first sensor 26 and enabling the flatness detection unit 2 to detect the plate with different error standards to ensure the accuracy of the detection. The locking bolt 266 moves in the threaded hole 265 to lock and unlock the position of the adjustment box 261.

[0043] In order to facilitate the lifting of the laminating wheel 23 by the sheet and control the first sensor 26 to start detection after reaching the working position, the following features are specifically set:

[0044] Both ends of the mounting frame 21 are provided with a linear drive 27, and the working end of the linear drive 27 is arranged toward the hanging ear 263 and moves in the vertical direction (such as Fig. 9 As shown in the figure, a mounting box 271 is provided on the working end of the linear drive 27, a second sensor 272 is fixedly installed in the mounting box 271, and the working end of the second sensor 272 is arranged toward the hanging ear 263.

[0045] In this embodiment, the linear drivers 27 on both sides of the mounting frame 21 push the bonding plate 262 to compress the second spring 214 away from the horizontal plate 25 in the non-working state. At this time, when one end of the plate contacts the bonding wheel 23, it only needs to compress the first spring 243 to drive the bonding wheel 23 to lift. When the working end of the linear driver 27 is reset, the elastic force of the second spring 214 causes the bonding plate 262 to move toward the horizontal plate 25. After the bonding plate 262 is bonded to the horizontal plate 25, the working end of the linear driver 27 continues to move and separates from the hanging ears 263 at both ends of the bonding plate 262. After the second sensor 272 on the working end of the linear driver 27 detects that the pressure disappears, it can send a signal to the controller, and the controller controls the first sensor 26 to start detection.

[0046] In order to solve the problem of how the conveying unit 12 controls the plate to move in the forward and reverse directions, the following features are specifically set:

[0047] The conveying unit 12 includes a horizontally arranged fixed support plate 121 and a lifting support plate 122. The fixed support plate 121 is fixedly installed on both sides of the mounting bracket 11 and is located below the feeding platform 1. The lifting support plate 122 is slidably installed on the mounting bracket 11 and moves in the vertical direction. Conveying rollers 123 are rotatably installed at both ends of the fixed support plate 121 and the lifting support plate 122. The conveying rollers 123 are located on both sides of the flatness detection unit 2.

[0048] The conveying unit 12 in this embodiment includes a fixed support plate 121 and a lifting support plate 122. The conveying rollers 123 at both ends of the fixed support plate 121 are located below the feeding platform 1, and the conveying rollers 123 at both ends of the lifting support plate 122 are located above the feeding platform 1. The lifting support plate 122 is slidably installed on the mounting bracket 11 to keep the moving path stable in the vertical direction. The lifting support plate 122 can be connected to the working end of the cylinder or the electric push rod to achieve movement in the vertical direction, and the conveying rollers 123 can be driven to rotate by the working end connected to the servo motor. In this embodiment, the conveying rollers 123 are respectively located on both sides of the flatness detection unit 2. Therefore, when the lifting support plate 122 moves down to the conveying rollers 123 to press the upper side of the plate, the plate can move according to the rotation direction of the conveying rollers 123.

[0049] In order to solve the problem of how the translation unit 3 drives the flatness detection unit 2 to translate, the following features are specifically set:

[0050] The translation unit 3 includes two shifting plates 31, which are respectively located on both sides of the feeding platform 1 (such as Figure 7 As shown in the figure, a first shaft rod 311 extending horizontally along the axis direction of the mounting rod 211 is provided at the center of the toggle plate 31, and the first shaft rod 311 is inserted on the fixed support plate 121. When the toggle plate 31 is vertical, its top protrudes from the upper surface of the feeding platform 1; a second shaft rod 312 parallel to the first shaft rod 311 is provided on one side of the bottom of the toggle plate 31, and the second shaft rods 312 on the two first shaft rods 311 are respectively inserted at both ends of the moving plate 32, and the moving plate 32 is horizontally arranged, and a contact plate 321 extending vertically upward is provided on the upper side of the moving plate 32 (as shown in the figure). Figure 7 and Fig.11 As shown); second guide rods 215 extending outwardly parallel to the mounting rods 211 are arranged on both sides of the mounting frame 21, the second guide rods 215 are inserted on the mounting bracket 11 and extend outwardly, the top of the second guide rods 215 is fixedly connected to the limit head 216, and a contact block 217 extending vertically downward is arranged below the limit head 216 close to the contact plate 321 side, and a third spring 218 (combined with the second guide rod 215 on the side away from the contact plate 321) is sleeved. Figure 1 and Fig.14), the third spring 218 elastically connects the limit head 216 and the outer wall of the mounting bracket 11, and the elastic force of the third spring 218 makes the contact block 217 fit the outer wall of the contact plate 321; the outer wall of the contact plate 321 is provided with a protrusion 322 (such as Fig.11 As shown in FIG. 2 ), when the protrusion 322 is in contact with the contact block 217 , it pushes the installation frame 21 to move along the axis of the second guide rod 215 .

[0051] In this embodiment, toggle plates 31 are provided on both sides of the installation frame 21. The toggle plates 31 are rotatably installed on the fixed support plate 121 through the first shaft rod 311. In a normal state, the toggle plates 31 are kept vertical by the gravity of the movable plate 32 connected to the bottom. The top of the toggle plates 31 protrudes from the upper surface of the feeding platform 1. When the plate contacts the toggle plate 31 from one side, it pushes the toggle plate 31 to tilt to one side, thereby driving the movable plate 32 to translate. The contact plate 321 provided on the movable plate 32 fits the limit of one side of the installation frame 21 of the flatness detection unit 2 The contact block 217 is arranged on the positioning head 216, and the limiting head 216 on the other side of the mounting frame 21 is subjected to the elastic force of the third spring 218 to keep the contact block 217 in contact with the contact plate 321. When the other side of the plate completely passes over the two toggle plates 31 and moves in the opposite direction, the toggle plates 31 tilt toward the other side, and the reverse translation of the moving plate 32 causes the protrusion 322 on the contact plate 321 to contact the contact block 217, thereby driving the contact block 217 and the mounting frame 21 to compress the third spring 218 and translate, thereby changing the contact position between the fitting wheel 23 and the plate.

[0052] In order to ensure that the laminating wheel 23 is in full contact with the plate, the following features are specifically provided:

[0053] The thickness of the laminating wheel 23 is the same as the distance between two adjacent laminating wheels 23 , and the thickness of the protrusion 322 is the same as the thickness of the laminating wheel 23 .

[0054] In this embodiment, the distance that the protrusion 322 pushes the contact block 217 to move is the same as the spacing between the bonding wheels 23, so it can be ensured that the bonding wheel 23 can completely contact the part that was not contacted by the bonding wheel 23 during the last inspection after translation, ensuring comprehensive inspection of the plate.

[0055] In order to ensure that the contact plate 321 on the moving plate 32 is located between the contact block 217 and the outer wall of the mounting frame 21, the following features are specifically provided:

[0056] The movable plate 32 is attached to the outer wall of the fixed support plate 121 , and the fixed support plate 121 is provided with an avoidance groove 124 for avoiding the moving path of the second shaft rod 312 .

[0057] The movable plate 32 in this embodiment fits against the outer wall of the fixed support plate 121 to ensure that the contact plate 321 on the movable plate 32 is located between the contact block 217 and the mounting frame 21 , and the second shaft rod 312 on the toggle plate 31 passes through the avoidance groove 124 on the fixed support plate 121 and is connected to both ends of the movable plate 32 .

[0058] Working principle: When in use, the staff places the plate to be tested on the feeding platform 1, and the conveying unit 12 conveys the plate from the positive direction through the flatness detection unit 2 on the mounting bracket 11. The plate pushes away the bonding wheels 23 on the upper and lower sides of the flatness detection unit 2, and the bonding wheels 23 are respectively bonded to the upper and lower sides of the plate.

[0059] The lifting rod 24 compresses the first spring 243 to lift the position of the horizontal plate 25. At this time, the horizontal plate 25 linked to the bonding wheels 23 that are in contact with the plate is higher than the position of the horizontal plate 25 linked to the bonding wheels 23 that are not in contact with the plate. The bonding plate 262 moves down and fits with the horizontal plate 25 to limit movement. At this time, the first sensors 26 at both ends of the bonding plate 262 are located on the lower side of the horizontal plate 25. Taking the upper bonding wheel 23 as an example, when a certain part of the upper side of the plate bulges upward, the bonding wheel 23 that contacts this position drives the power arm 22 to flip upward. At this time, the lifting rod 24 connected to the power arm 22 moves upward, and the horizontal plate 25 at the top of the lifting rod 24 moves upward to lift the bonding plate 262. At this time, the position of the first sensor 26 is raised, and the laser emitted by the first sensor 26 is blocked by the horizontal plate 25 that remains unchanged in other positions. Therefore, the first sensor 26 can send a signal to indicate that there is an unevenness at this position; when a certain part of the upper side of the plate bulges upward, the bonding wheel 23 that contacts this position drives the power arm 22 to flip upward. When it is concave, the bonding wheel 23 in contact with this position drives the power arm 22 to flip downward. At this time, the lifting rod 24 connected to the power arm 22 moves downward, and the horizontal plate 25 on the top of the lifting rod 24 moves downward. Since the position of the bonding plate 262 remains unchanged, the downward-moving horizontal plate 25 blocks the laser emitted by the first sensor 26. Therefore, the first sensor 26 can send a signal indicating that there is unevenness at this position. After the plate passes through the flatness detection unit 2 along the square, the conveying unit 12 can drive the plate to pass through the flatness detection unit 2 again in the opposite direction. At this time, the translation unit 3 automatically drives the mounting frame 21 of the flatness detection unit 2 to translate along the axial direction of the mounting rod 211, thereby changing the contact position between the bonding wheel 23 and the plate. When the plate passes through the flatness detection unit 2 in the opposite direction, the plate is subjected to a secondary inspection to ensure the comprehensiveness of the flatness inspection. The staff can take the plate away after the plate is reset.
