Description

Technical Field

[0001] This invention relates to the field of prefabricated building component production and testing technology, specifically to an intelligent detection and sorting device for defects in prefabricated components. Background Technology

[0002] Prefabricated construction transfers the on-site casting work of traditional construction methods to factories. Through standardized design, factory production, and assembly construction, it realizes the industrialized production of building components (such as precast concrete floor slabs, composite slabs, precast beams and columns, steel structure components, etc.). With the country's vigorous promotion of prefabricated construction, the proportion of prefabricated buildings in new buildings has been increasing year by year, which has put forward higher requirements for the production quality and testing efficiency of precast components.

[0003] In the factory production of prefabricated components, defect detection is a key aspect of quality control. Common defects include surface cracks, honeycomb pitting, dimensional deviations, missing or misaligned embedded parts, and insufficient concrete cover thickness. Existing prefabricated component inspection and sorting devices, taking precast concrete slabs as an example, require inspecting one side of the slab first, then flipping it over to inspect the other side. However, in existing technologies, because both sides of the precast concrete slab are inspected at the same workstation, continuous inspection and flipping are not possible, resulting in low efficiency. Furthermore, the same workstation leads to positional discrepancies between the precast concrete slab before and after flipping, creating blind spots and low accuracy.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0008] Furthermore, the flipping unit includes: The support frame consists of two sets, which are positioned across the top of the first and second transmission units.

[0011] Furthermore, a limit shaft is rotatably connected to the contact surface between the clamp and the concrete floor slab; A ball bearing is sleeved on the outside of the limiting shaft and inside the top shaft. The ball bearing is used to reduce friction when the clamping piece moves relative to the concrete floor slab.

[0012] Furthermore, the second transmission unit includes: The second conveying mechanism is located on the side of the flipping unit away from the first conveying unit, and is used to receive the flipped concrete floor slab and move it. The second detection probe is located above the second conveying mechanism and is used to detect the second surface of the concrete floor slab.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8 The present invention provides a technical solution: A smart detection and sorting device for defects in prefabricated components is used for double-sided detection and sorting of precast concrete floor slabs 100, comprising: The first conveying unit 1 is used to detect and convey the first surface of the concrete floor slab 100; The flipping unit 2 is located at the output end of the first conveying unit 1 and is used to lift the concrete floor slab 100 from the first conveying unit 1 and flip it to the second conveying unit 3. The second conveying unit 3 is used to inspect the second surface of the flipped concrete floor slab 100 and sort and export the concrete floor slab 100 based on the inspection results.

[0023] As an improvement, such as Figure 1 As shown, the first transmission unit 1 includes: The first conveying mechanism 11 is used to drive the concrete floor slab 100 to move along the first direction; The first centering plate 12 is located inside the first conveying mechanism 11 and is used to guide and center the moving concrete floor slab 100. The first detection probe 13 is located above the first conveying mechanism 11 and is used to detect the first surface of the moving concrete floor slab 100. A stop bar 14 is located at the output end of the first conveying mechanism 11 and is used to block and position the tested concrete floor slab 100.

[0024] Furthermore, such as Figure 2-5 As shown, the flipping unit 2 includes: The support 21 is provided in two sets, spanning across the top of the first transmission unit 1 and the second transmission unit 3; A crossbeam 22 is fixedly connected between the upper parts of the two sets of brackets 21; Mounting frame 23 is fixedly connected to the upper end of the crossbeam 22 near one side; A sliding component 26 is disposed at the upper end of the bracket 21 and is used to switch positions between the first transmission unit 1 and the second transmission unit 3. The flipping component 27 is connected below the sliding component 26 and is used to clamp, lift and flip the concrete floor slab 100.

[0025] Furthermore, such as Figure 1-2 As shown, the sliding component 26 includes: The movable plate 261 is slidably disposed between the two sets of brackets 21; Guide wheels 262 are rotatably connected to both sides of the movable plate 261 and roll in cooperation with the upper end of the bracket 21; Driven gear 2621 is coaxially and fixedly connected to one side of guide wheel 262; The mounting frame 23 is equipped with a first drive motor 24 and a first drive gear 25. The first drive gear 25 is connected to the driven gear 2621 via a chain 251.

[0026] Among them, such as Figure 2-4 As shown, the flipping component 27 includes: The fixed frame 271 is fixedly connected to the output end of the cylinder 263 below the movable plate 261; U-shaped block 274 is fixedly connected to the lower end of the fixed frame 271, and through holes 2741 are symmetrically provided on both sides of the U-shaped block 274; The top shaft 276 is slidably inserted into the corresponding through hole 2741; A clamping piece 277 is provided at one end of the top shaft 276 near the concrete floor slab 100 and is used to clamp the side of the concrete floor slab 100. The second drive motor 272 is installed on one side of the fixed frame 271; The second drive gear 273 is connected to the output end of the second drive motor 272; The rack rod 275 is symmetrically arranged on both sides of the second drive gear 273 and meshes with it. One end of the rack rod 275 is fixedly connected to the corresponding top shaft 276 through the clamping rod 2751.

[0027] In addition, a limit shaft 2771 is rotatably connected to the contact surface between the clip 277 and the concrete floor slab 100; A ball bearing 2772 is sleeved on the outside of the limiting shaft 2771 and inside the top shaft 276. The ball bearing 2772 is used to reduce friction when the clamping piece 277 moves relative to the concrete floor slab 100.

[0028] As an improvement, such as Figure 1 , Figure 8 As shown, the second transmission unit 3 includes: The second conveying mechanism 31 is located on the side of the flipping unit 2 away from the first conveying unit 1, and is used to receive the flipped concrete floor slab 100 and drive it to move. The second detection probe 33 is located above the second conveying mechanism 31 and is used to detect the second surface of the concrete floor slab 100. The sorting mechanism is located at the output end of the second conveying mechanism 31 and is used to extract the concrete floor slab 100 from the second conveying mechanism 31 according to the detection results.

[0029] Furthermore, such as Figure 8 As shown, the sorting mechanism includes: The first electric cylinder 321 is fixedly connected to one side of the second conveying mechanism 31, and the output end of the first electric cylinder 321 is provided with a first stop block 3211; The first discharge channel 311 is located on the other side of the second conveying mechanism 31 and is opposite to the first electric cylinder 321. The second electric cylinder 322 is fixedly connected to one side of the second conveying mechanism 31 and located downstream of the first electric cylinder 321. The output end of the second electric cylinder 322 is provided with a second stop block 3221. The second outlet channel 312 is located on the other side of the second conveying mechanism 31 and is opposite to the second electric cylinder 322; A base plate 32 for supporting the first electric cylinder 321 and the second electric cylinder 211 is installed on one side of the second conveying mechanism 31.

[0030] Furthermore, the tail end of the second conveying mechanism 31 is provided with a storage frame 34, which is used to receive the concrete floor slab 100 output from the end of the second conveying mechanism 31 in the event of a failure of the first electric cylinder 321 or the second electric cylinder 322.

[0031] The second conveying mechanism 31 has a second centering plate on its inner side, which is used to guide and center the overturned concrete floor slab 100. Both the first conveying mechanism 11 and the second conveying mechanism 31 are roller conveyors or belt conveyors.

[0032] It should be noted that, in the specific implementation of this invention, such as... Figure 1 , Figure 6 As shown, when it is necessary to inspect the concrete floor slab 100, the concrete floor slab 100 is placed onto the first conveying mechanism 11 by a robotic arm. The first conveying mechanism 11 drives the concrete floor slab 100 to be conveyed under the first detection probe 13. During this process, the two sets of first centering plates 12 located inside the first conveying mechanism 11 guide and center the concrete floor slab 100. The first detection probe 13 detects one side of the moving concrete floor slab 100. After one side of the concrete floor slab 100 is detected, it is sent to one side of the stop bar 14. The stop bar 14 blocks the concrete floor slab 100 to complete the automatic detection of one side of the concrete floor slab 100. like Figure 2-6 As shown, subsequently, the cylinder 263, located directly above the concrete floor slab 100 blocked by the stop bar 14, synchronously drives the U-shaped block 274 and the top shaft 276 downward through the fixed frame 271, causing the top shaft 276 to move downward to both sides of the concrete floor slab 100 near one end. This activates the second drive motor 272, which rotates via the second drive gear 273. The second drive gear 273 synchronously drives the rack 275 meshing at its upper and lower ends to move in the opposite direction. The rack 275, through the clamping rod 2751, drives the top shaft 276 to move along the corresponding through hole 2741. 6. The clamping plates 277 are clamped on both sides of the concrete floor slab 100 near one end. Then, the cylinder 263 drives the top shaft 276 to move upward through the fixed frame 271. The top shaft 276 drives the concrete floor slab 100 at the end of the stop bar 14 to be gradually lifted from the top of the first conveying mechanism 11 through the clamping plates 277. At this time, the concrete floor slab 100 drives the limiting shaft 2771 to rotate in the top shaft 276 through friction with the clamping plates 277. The limiting shaft 2771 drives the ball bearing 2772 to roll in the top shaft 276, realizing the flipping of the concrete floor slab 100 from the horizontal state to the vertical state. like Figure 6-8As shown, the first drive motor 24 is then started, which drives the first drive gear 25 inside the mounting frame 23 to rotate. The first drive gear 25 drives the driven gear 2621 to rotate via the chain 251. The driven gear 2621 drives the guide wheel 262 to move along the upper end of the bracket 21 toward the second conveying unit 3, so that the guide wheel 262 drives the moving plate 261 to move toward the second conveying unit 3 via the shaft. The moving plate 261 drives the fixed frame 271 to move via the cylinder 263. The fixed frame 271 drives the top shaft 276 to move via the U-shaped block 274. The top shaft 276 drives the concrete floor slab 100 to move to the second conveying unit 3 via the clamping piece 277. Above mechanism 31, cylinder 263 drives U-shaped block 274 to move downward through fixed frame 271. U-shaped block 274 drives clamping piece 277 to move downward through top shaft 276, so that concrete floor slab 100 is lowered to the upper end of second conveying mechanism 31. When the lower end of concrete floor slab 100 contacts the upper end of second conveying mechanism 31 in the conveying state, under the friction of second conveying mechanism 31 on concrete floor slab 100, concrete floor slab 100 switches from vertical state to horizontal state, controls second drive motor 272 to rotate in the opposite direction, so that clamping piece 277 separates from concrete floor slab 100, completing the automatic transportation and flipping of concrete floor slab 100. like Figure 1 , Figure 8 As shown, after the concrete floor slab 100 is released to the upper end of the second conveying mechanism 31, the second conveying mechanism 31 drives the concrete floor slab 100 to move, and after being centered by the second centering plate fixedly connected to the inner side of the second conveying mechanism 31, it moves past the lower part of the second detection probe 33. The second detection probe 33 completes the detection of the other side of the concrete floor slab 100, and then the second conveying mechanism 31 drives the concrete floor slab 100 after the detection is completed to continue moving forward. like Figure 1 , Figure 8 As shown, if both sides of the concrete floor slab 100 pass the inspection, the concrete floor slab 100 is blocked by the second stop block 3221 when it moves to the output end of the second electric cylinder 322. At this time, the second electric cylinder 322 pushes the concrete floor slab 100 from the second conveying mechanism 31 into the second discharge channel 312 for discharge. If two surfaces of the concrete floor slab 100 fail the inspection, the concrete floor slab 100 will be blocked by the first stop block 3211 when it moves to the output end of the first electric cylinder 321. At this time, the first electric cylinder 321 will push the concrete floor slab 100 from the second conveying mechanism 31 to the first export channel 311 for export, thereby realizing the automatic screening of the inspected concrete floor slab 100. like Figure 1As shown, the tail end of the second conveying mechanism 31 in this invention is provided with a storage frame 34. When the control system of the first electric cylinder 321 or the second electric cylinder 322 malfunctions and the concrete floor slab 100 is not brought out from the second conveying mechanism 31, the storage frame 34 can promptly store the concrete floor slab 100 brought out by the second conveying mechanism 31 to prevent the concrete floor slab 100 from falling to the ground and causing damage.
