Description

Technical Field

[0001] This utility model relates to a screening device, and more particularly to a bar screening device for bar production. Background Technology

[0002] In the production of bar stock, quality screening is a crucial step in ensuring the finished product's pass rate, and its importance is self-evident. As a fundamental raw material for many industrial products, bar stock is widely used in machinery manufacturing, automobile production, aerospace, and many other fields. The quality of the bar stock directly affects the performance, reliability, and service life of the finished products. If substandard bar stock enters the production process, it may lead to quality problems in the finished products, increase production costs, and even affect product safety.

[0003] Traditional screening methods rely heavily on manual visual inspection or simple mechanical sorting devices. Manual visual inspection is extremely inefficient, requiring workers to concentrate on observing the bars for extended periods, which can easily lead to visual fatigue. This not only results in high labor intensity but also a high rate of missed inspections. Existing mechanical screening equipment typically uses size screening or weight sorting, which makes it difficult to accurately identify surface defects in the bars and lacks automated classification functions, leading to defective products being mixed with qualified products and affecting overall quality. Utility Model Content

[0004] To overcome the difficulty in accurately identifying surface defects in bar stock, this invention provides a bar stock screening device for bar stock production.

[0005] A bar screening device for bar production includes a support frame, a CCD camera, a collection bin, a first motor, a conveyor belt, a support frame, a controller, a connecting block, a second motor, a support rod, and a belt. The CCD camera, which has a built-in image analysis and processing module, is mounted on the support frame. A controller is located on top of the CCD camera, and the image analysis and processing module is electrically connected to the controller. A conveyor belt is mounted on the support frame, and support frames are evenly distributed along the conveyor belt. A first motor is located on one side of the support frame and is electrically connected to the controller. The output shaft of the first motor is connected to a pulley at one end of the conveyor belt. A collection bin is located at one end of the support frame, and a connecting block is located on top of the collection bin. A second motor is mounted on the connecting block, and a support rod is mounted on the connecting block. A belt is mounted on the support rod, and the output shaft of the second motor is connected to a pulley at one end of the belt. The pulley of the belt is rotatably connected to the support rod.

[0006] Furthermore, it also includes a storage bin, a cylinder, a push plate, a fixed plate, and a conveying plate. The storage bin is located at one end of the support frame. The cylinder is located inside the storage bin. The piston of the cylinder is equipped with a push plate. The storage bin is located inside a bottom plate. The bottom plate is equipped with a fixed plate. The push plate is slidably connected to the bottom plate and the fixed plate respectively. The bottom plate, the push plate, and the fixed plate are all inclined. The lower end of the bottom plate faces the push plate and the fixed plate. The push plate and the fixed plate are inclined at 30° clockwise. The top of the storage bin is equipped with a conveying plate, which is connected to the top of one end of the support frame.

[0007] Furthermore, the thickness of the push plate and the fixing plate is the same as the diameter of the bar stock.

[0008] Furthermore, it also includes a stop block, with a stop block provided at one end of the connection between the conveyor plate and the support.

[0009] Furthermore, it also includes baffles, with baffles installed on the bracket.

[0010] Furthermore, it also includes a collection box, a V-shaped plate, a third motor, and a connecting rod. The collection box is installed inside the collection chamber, and there is a distance between the collection box and the collection chamber for the bar to pass through. This distance is greater than the diameter of the bar. The bottom surface of the collection chamber is equipped with a third motor, and the output shaft of the third motor is connected to the connecting rod. The connecting rod is rotatably connected to the collection chamber. A V-shaped plate is installed on the connecting rod, and a through hole is provided on the collection chamber. The V-shaped plate is slidably connected to the through hole.

[0011] The beneficial effects are as follows: 1. This utility model enables the bar stock to rotate at a uniform speed during the detection process through the linkage control of CCD camera, controller, belt and second motor, so as to achieve all-round surface detection without dead angles and significantly improve the accuracy of defect identification.

[0012] 2. The pushing mechanism consisting of an inclined pusher plate, a fixing plate, and a cylinder in the storage box of this utility model, combined with the design of matching the thickness of the pusher plate with the diameter of the bar, ensures that only one bar is pushed at a time, avoiding multiple materials from overlapping or jamming, and ensuring the stability of the conveyor belt's material supply.

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] A bar screening device for bar production, such as Figures 1-6 As shown, the system includes a bracket 1, a CCD camera 4, a collection chamber 5, a first motor 6, a conveyor belt 7, a support frame 14, a controller 15, a connecting block 18, a second motor 19, a support rod 20, and a belt 21. The CCD camera 4 is located at the left end of the bracket 1. The CCD camera 4 has a built-in image analysis and processing module. The controller 15 is located on the top of the CCD camera 4, and the image analysis and processing module of the CCD camera 4 is electrically connected to the controller 15. The conveyor belt 7 is mounted on the bracket 1, and the support frames 14 are evenly distributed on the conveyor belt 7. The first motor 6 is provided on the side and is electrically connected to the controller 15. The output shaft of the first motor 6 is connected to the pulley at one end of the conveyor belt 7. The collection bin 5 is provided on the left end of the bracket 1. Two connecting blocks 18 are provided on the top of the collection bin 5. The second motor 19 is provided on each of the connecting blocks 18. The support rod 20 is provided on the connecting blocks 18. The belt 21 is provided on the support rod 20. The output shaft of the second motor 19 is connected to the pulley at one end of the belt 21. The pulley of the belt 21 is rotatably connected to the support rod 20.

[0022] When using this device for bar stock screening, the controller 15 starts the first motor 6. The output shaft of the first motor 6 rotates, driving the pulley of the conveyor belt 7 to rotate, thereby moving the conveyor belt 7 and placing the bar stock onto the support frame 14 on the conveyor belt 7. The bar stock on the support frame 14 moves through the conveyor belt 7 into the imaging range of the CCD camera 4. The CCD camera 4 captures the bar stock and sends the image to the image analysis and processing module. After processing and analyzing the image, the image analysis and processing module sends a signal to the controller 15. The controller 15 controls the first motor 6 to shut down. At this time, the bar stock is in contact with the upper surface of the belt 21. The second motor 19 starts, and the second... The output shaft of motor 19 rotates, driving the pulley of belt 21 to rotate, thereby driving belt 21 to rotate. Under the drive of belt 21, the bar stock begins to rotate slowly under the constraint of support frame 14. CCD camera 4 continues to take pictures of the surface of the bar stock and sends them to image analysis and processing module. Image analysis and processing module analyzes the multiple images sent by CCD camera 4. After the image analysis and processing module completes the analysis, it sends a signal to controller 15. Controller 15 controls the first motor 6 to start, and the conveyor belt 7 continues to move. The bar stock moves onto belt 21. Supported by belt 21, the bar stock detaches from support frame 14 and is transported to collection bin 5 by belt 21.

[0023] like Figure 1 and Figure 2 As shown, the system also includes a storage bin 2, a cylinder 8, a push plate 9, a fixed plate 10, and a conveying plate 12. The storage bin 2 is located at the right end of the support 1. The cylinder 8 is located on the bottom surface inside the storage bin 2. At least two push plates 9 are located on the piston of the cylinder 8. A bottom plate 11 is located inside the storage bin 2. The fixed plate 10 is located on the bottom plate 11. The push plate 9 is slidably connected to the fixed plate 10. The push plate 9 passes through the bottom plate 11 and is slidably connected to it. The bottom plate 11, the push plate 9, and the fixed plate 10 are all inclined. The lower end of the bottom plate 11 faces the push plate 9 and the fixed plate 10. The push plate 9 and the fixed plate 10 are inclined at a clockwise angle of 30°. The conveying plate 12 is located on the top of the storage bin 2 and is connected to the top of one end of the support 1.

[0024] Before screening the bar stock, the bar stock can be placed into the storage bin 2. The placed bar stock will first fall onto the base plate 11, and then, under the action of gravity, move towards the lower end of the base plate 11 and to the top of the push plate 9. The cylinder 8 is then activated, and its piston extends, pushing the push plate 9 upwards at an angle. The bar stock moves upwards under the constraint of the fixed plate 10. When the top of the push plate 9 and the top of the fixed plate 10 are on the same plane, the piston of the cylinder 8 stops extending, and the bar stock moves to the top of the fixed plate 10 under the action of gravity. Then, the process is started... When the piston of the cylinder 8 retracts, the push plate 9 moves downward. When the top of the push plate 9 is on the same plane as the upper surface of the base plate 11, the piston of the cylinder 8 stops retracting. The bar stock moves to the top of the push plate 9 under the action of gravity. The bar stock located on the top of the fixed plate 10 will fall onto the next-level push plate 9. Then the piston of the cylinder 8 repeats the action of extending and retracting, which can transport the bar stock from the base plate 11 to the top of the storage box 2, and then fall onto the conveyor plate 12, and be transported to the conveyor belt 7 by the conveyor plate 12.

[0025] like Figure 2 As shown, the thickness of the pusher plate 9 and the fixing plate 10 is the same as the diameter of the bar stock. Because the thickness of the pusher plate 9 is the same as the diameter of the bar stock, the pusher plate 9 will only push one bar stock at a time, avoiding multiple bar stocks being transported onto the conveyor belt 7 together, which would cause the bar stocks on the conveyor belt 7 to become messy and affect the detection of the CCD camera 4.

[0026] like Figure 3 As shown, it also includes a stop block 13, which is provided at one end of the connection between the conveyor plate 12 and the support 1. The stop block 13 provided at one end of the connection between the conveyor plate 12 and the support 1 can prevent the bar stock from sliding off the conveyor plate 12, avoid excessive movement of the bar stock, and allow the bar stock to fall stably onto the support frame 14.

[0027] like Figure 1 and Figure 3 As shown, the support also includes baffles 3, which are provided on both the left and right sides of the support 1. The baffles on the support 1 are used to protect the bar material on the conveyor belt 7 and prevent the bar material from falling off the conveyor belt 7 during transportation.

[0028] like Figure 4 and Figure 6As shown, it also includes a collection box 16, a V-shaped plate 17, a third motor 22, and a connecting rod 23. The collection box 16 is installed inside the collection chamber 5. A distance is left between the collection box 16 and the collection chamber 5 for the bar stock to pass through. This distance is greater than the diameter of the bar stock. Three third motors 22 are installed in sections on the bottom surface of the collection chamber 5. The output shaft of the third motor 22 is connected to the connecting rod 23. The connecting rod 23 is rotatably connected to the collection chamber 5. The V-shaped plate 17 is installed on the connecting rod 23. The collection chamber 5 has a through hole. The V-shaped plate 17 is slidably connected to the through hole.

[0029] After the image analysis and processing module built into the CCD camera 4 analyzes and processes the bar stock, it will distinguish and complete the three-level classification based on the surface quality of the bar stock. The image analysis and processing module sends the classification signal to the controller 15. If a first-level classification signal is sent, the controller 15 only controls the third motor 22 of the first-level classification to rotate forward. The output shaft of the third motor 22 rotates, driving the connecting rod 23 to rotate. The rotation of the connecting rod 23 drives the two V-shaped plates 17 to rotate. The V-shaped plates 17, which were originally located on the back of the collection chamber 5, rotate. Driven by the third motor 22, the V-shaped plate 17 rotates its V-shaped opening towards the inside of the collection bin 5. The bottom surface of the V-shaped plate 17 contacts the collection box 16, and the top surface of the V-shaped plate 17 remains parallel to the bottom surface of the collection bin 5. When the screened bar stock slides down the bottom surface of the collection bin 5, it will fall along the V-shaped plate 17 into the primary sorting collection box 16 located at the top of the collection bin 5. Then, the controller 15 controls the third motor 22 of the primary sorting to reverse, causing the V-shaped plate 17 of the primary sorting to rotate again. The back of the collection bin 5 does not affect the subsequent two stages of bar stock entering the corresponding collection boxes 16. If a secondary classification signal is sent, the controller 15 only controls the third motor 22 of the secondary classification to rotate forward, and the bar stock will fall through the V-shaped plate 17 of the secondary classification into the secondary classification collection box 16 located in the middle of the collection bin 5. Then, the controller 15 controls the third motor 22 of the secondary classification to rotate in reverse, causing the V-shaped plate 17 of the secondary classification to rotate back to the back of the collection bin 5. If a tertiary classification signal is sent... The controller 15 controls the third motor 22 of the three-level sorting to rotate forward, and the bar stock will fall through the V-shaped plate 17 of the three-level sorting into the collection box 16 of the three-level sorting located at the bottom of the collection bin 5. Then, the controller 15 controls the third motor 22 of the three-level sorting to rotate the V-shaped plate 17 of the three-level sorting back to the back of the collection bin 5. The bar stock is sorted in three levels through the cooperation of the CCD camera 4, the controller 15, the third motor 22 and the V-shaped plate 17.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
