Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a feeding device for detecting bolts in steel structures. Background Technology

[0002] In the production and assembly of steel components, bolts are key connecting parts. Defects such as bending and skewing of bolts can directly affect the stability and safety of the overall structure. Therefore, bolt quality inspection is a crucial step. Currently, the industry generally uses visual inspection devices to detect the bending and skewing of bolts. These devices can quickly and accurately determine whether bolts have defects through high-precision image recognition technology, greatly improving the accuracy of inspection.

[0003] However, in the actual testing process, there are obvious pain points in the bolt loading process. For smaller companies, due to limitations in funds, space and production scale, they often cannot equip themselves with automated loading equipment and can only rely on manual placement of the bolts to be tested one by one into the testing position. This manual loading method not only consumes a lot of labor costs, but also makes it easy for workers to get tired from repetitive operations for a long time, which can lead to problems such as unstable loading speed and bolt placement deviation, directly reducing the overall testing efficiency and making it difficult to meet the testing needs of mass production.

[0004] To improve production efficiency, large enterprises often use robotic arms to load bolts. While robotic arms can automate loading and ensure stability and speed, they are expensive to purchase and require professional technicians for installation, debugging, and maintenance. Subsequent operation and maintenance costs are also significant. This is undoubtedly a heavy burden for many small and medium-sized enterprises, making it difficult for them to afford such a high investment in equipment. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for inspecting bolts on steel components, comprising an operating table, on which a chain drive device is installed, and a vision inspection device and a feeding assembly are respectively installed on the chain drive device. The operating table is also equipped with a feeding assembly that cooperates with the feeding assembly. Several bearing plates are installed on the chain of the chain drive device. The feeding assembly includes a belt conveyor, with horizontal plates fixed at both ends of the belt conveyor. Multiple strips are fixed between the horizontal plates, and the distance between the strips forms a feeding channel. A support block is fixed between the heads of every two sets of strips. A stop block located in the feeding channel is fixed at the bottom of the support block. One side of the stop block is arc-shaped, and a sensing sensor is installed inside it.

[0006] Furthermore, the feeding assembly includes a frame plate and a side plate. A linear module is mounted on the frame plate. The moving end of the linear module is fixed with a moving plate that slides with the side plate. A push cylinder is mounted on the moving plate. The piston rod of the push cylinder is fixed with a push plate. The push plate is equipped with a number of clamping cylinders equal to the number of feeding channels.

[0007] Furthermore, the support plate includes a bottom block, an upper block is mounted on the bottom block, and the upper block is provided with a plurality of placement holes, in which an open cylinder is fixed.

[0008] Furthermore, a notch plate is fixed between the bottom block and the top block, and a positioning component is fixed on the operating table. The positioning component includes multiple support frames, a push cylinder is installed on the top of the support frame, and a push plate is slidably connected to the piston rod of the push cylinder. The push plate is provided with a top plate that can be adapted to the notch of the notch plate.

[0009] Furthermore, an adjustment block is fixed to the top of the push plate, a slide is provided in the middle of the adjustment block, and multiple positioning holes are provided on both sides of the top. The top plate is located in the slide, and a locking plate is fixed to the top of the top plate by screws and locking it to the positioning holes.

[0010] Furthermore, the upper block is internally provided with multiple top rods that can extend into the opening cylinder, and multiple waist holes are opened at the top. The top of the top rod is fixed with a protruding post located in the waist hole. The end of the top rod opposite to the opening cylinder is arc-shaped, and the other end is fixed with a side block. A guide wheel is installed on the side block. A spring is sleeved on the outside of the top rod. The operating table is fixed with a vertical plate distributed opposite to the visual inspection device, and a trapezoidal block is installed on the top of the vertical plate.

[0011] Furthermore, a sleeve plate is fixed to the top of the upright plate. The sleeve plate is hollow and has an elongated opening at the top. The trapezoidal block slides inside the sleeve plate and is locked and fixed by screws passing through the elongated opening.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This bolt inspection and feeding device for steel components achieves orderly bolt delivery through a feeding assembly. It uses inductive sensors to accurately detect the bolt position, and works with the clamping cylinder, linear module, and push cylinder of the feeding assembly to complete the automated transfer of bolts from the feeding assembly to the carrier plate. This replaces manual feeding, improves efficiency, and reduces labor costs. The chain drive device moves the carrier plate, and the push cylinder and top plate of the positioning assembly accurately position the carrier plate, ensuring the accuracy of feeding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7This embodiment of a feeding device for inspecting bolts on steel components includes an operating table 1. A chain drive device 2 is fixed on the top of the operating table 1. The chain drive device 2 adopts a conventional structure in which a motor drives a sprocket to rotate a chain in a circular motion. Multiple bearing plates 3 are installed on the chain of the chain drive device 2. The chain drive device 2 is used to realize the intermittent conveying of the bearing plates 3. Visual inspection devices 6 and feeding components 4 are also fixed on the operating table 1 and distributed on both sides of the chain drive device 2. The feeding components 4 are installed on the top of the operating table 1. The feeding components and the feeding components 4 cooperate to move the bolts onto the bearing plates and then convey them to the visual inspection devices through the chain drive device to complete the bending and skew detection.

[0024] like Figure 2 The automatic feeding assembly 4 includes a belt conveyor 41 fixed on the operating table 1. The conveying direction of the belt conveyor 41 is towards the chain drive device 2. Both ends of the belt conveyor 41 are fixed with horizontal plates. Multiple strips 42 are fixed between the horizontal plates. The spacing between the strips 42 is set according to the bolt specifications to form a feeding channel for limiting the bolt conveying trajectory. A support block 43 is fixed between the head ends of every two sets of strips 42. The bottom of the support block 43 is integrally formed with a stop block 44 located in the feeding channel. The side of the stop block 44 facing the bolt conveying direction is arc-shaped, which can reduce collision damage to the bolt. Furthermore, a sensor such as an infrared sensor is embedded inside the stop block 44 to detect the position status of the bolt in the feeding channel.

[0025] like Figure 3 The automatic feeding of bolts is achieved. The feeding component 5 includes a frame plate 51 and a side plate 52 fixed on the operating table 1 and distributed opposite each other. A linear module 53 is fixed on the side of the frame plate 51 opposite to the side plate 52. A moving plate 54 that slides with the side plate 52 is fixed to the moving end of the linear module 53 to ensure that the moving plate 54 moves smoothly. A push cylinder 55 is fixed on the moving plate 54. A push plate 56 is fixed to the piston rod end of the push cylinder 55. A number of clamping cylinders 57, the same as the feeding channel, are installed on the surface of the push plate 56. The clamping claws of the clamping cylinders 57 are adapted to the diameter of the bolts. Through the cooperation of the linear module, the push cylinder and the clamping cylinder, the bolts can be moved to the bearing plate to complete the feeding operation.

[0026] like Figure 5-6 The bearing plate 3 includes a bottom block 31 fixed on the chain of the chain drive device 2. A retaining plate 32 is fixed on the top of the bottom block 31. An upper block 33 is fixed on the top of the retaining plate 32. A pair of placement holes are provided on the upper block 33. An open cylinder 34 is embedded and fixed in the placement hole. The bolt is supported by the open cylinder, and the threaded end of the bolt extends out of the open cylinder.

[0027] like Figure 4A positioning component 7 is fixed on the side of the chain drive device 2 on the operating table 1. The positioning component 7 includes two support frames 71 fixed on the operating table 1. A push cylinder 72 is fixed on the top of the support frame 71, and a push plate 73 is slidably connected to the top of the support frame 71 through a slide rail. The push plate 73 is fixed to the piston rod end of the push cylinder 72. A top plate 76 is provided on the top of the push plate 73, which can be adapted to the notch of the notch plate 32. The positioning of the bearing plate 3 is achieved by the top plate 76 being inserted into the notch.

[0028] The push plate 73 has multiple adjusting blocks 74 fixed on its top. The adjusting blocks 74 have a slide rail in the middle and multiple equidistant positioning holes on both sides of the top. The top plate 76 slides in the slide rail. The top of the top plate 76 is integrally formed with a locking plate 75. The locking plate 75 has a through hole. The top plate 76 can be adjusted by screws passing through the through hole and cooperating with different positioning holes to adapt to different sizes of sill plates 32.

[0029] Additionally, a pair of push rods 35 are transversely inserted inside the upper block 33. One end of each push rod 35 extends into the interior of the open cylinder 34, forming an arc shape. A side block 38 is fixed between the other ends. A guide wheel 39 is mounted on the side of the side block 38 away from the push rods 35 via a pin. A pair of waist holes are opened at the top of the upper block 33. A protrusion 36 is fixed to the top of each push rod 35. The protrusion 36 slides within the waist holes, limiting the movement trajectory of the push rods 35. A spring 37 is sleeved on the outer side of each push rod 35. One end of the spring 37 abuts against the inner wall of the upper block 33, and the other end abuts against the side block 38, for resetting the push rod 35. A vertical plate 8 opposite to the vision inspection device is fixed on the operating table 1. A trapezoidal block 10 is installed on the top of the vertical plate 8. The head end of the trapezoidal block 10 is located on one side of the guide wheel 39. When the chain drive device drives the bearing plate to move, the guide wheel will push the side block through contact with the trapezoidal block, and push the push rod into the open cylinder to position the bolt, so as to avoid shaking during inspection.

[0030] To further explain, a sleeve plate 9 is fixed to the top of the upright plate 8. The sleeve plate 9 is a hollow rectangular structure with an elongated opening at the top. The trapezoidal block 10 slides inside the sleeve plate 9. The trapezoidal block 10 is fixed in position by screws passing through the elongated opening, thereby adjusting the timing of contact between the guide wheel 39 and the trapezoidal block 10.

[0031] The working principle of this embodiment is as follows:

[0032] The bolts to be tested are batched into the feeding channel of the feeding assembly. The belt conveyor is started, and simultaneously, the piston rod of the push cylinder extends, pushing the push plate to move so that the top plate is engaged in the notch of the notch plate, achieving precise positioning of the bearing plate. Under the action of belt friction, the bolts move along the feeding channel towards the stop block. When the bolt contacts the stop block, the arc surface of the stop block guides the bolt to be aligned. At this time, the sensing sensor detects the bolt and sends an electrical signal to the control system. After receiving the signal, the control system controls the linear module to start, driving the moving plate to slide along the side plate to the top of the feeding channel. Then, the piston rod of the push cylinder extends, driving the push plate and the clamping cylinder to move down. The clamping cylinder actuates to clamp the bolt. As the piston rod of the downward-pushing cylinder retracts and resets, the linear module drives the moving plate to move directly above the opening cylinder of the support plate. The downward-pushing cylinder extends again, the clamping cylinder releases, the bolt falls into the opening cylinder, the top plate retracts, and the chain drive device moves the support plate to the vision inspection device. When the guide wheel contacts the inclined surface of the trapezoidal block, as the support plate moves, the guide wheel drives the side block and the top rod to move towards the opening cylinder along the inclined surface. The top rod squeezes and positions the bolt, the vision inspection device starts, and performs bending and skew detection on the bolt, transmitting the detection data to the control system. After that, the support plate continues to move, the guide wheel disengages from the trapezoidal block, and the top rod resets under the action of the spring force, waiting for the next cycle.

[0033] The entire device achieves automated feeding, positioning, detection, and unloading through the combination of mechanical structure and sensors, without the need for manual intervention. It has a simple structure and lower cost than robotic arms, solving the cost pain point of small and medium-sized enterprises. At the same time, the adjustable structure improves the versatility of the device.

[0034] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
