Description

Technical Field

[0001] This application relates to the field of equipment for producing steel cages, and in particular to an intelligent CNC steel cage forming and welding production line. Background Technology

[0002] A reinforcing cage is the skeleton of a pile. It includes multiple annular reinforcing bars, multiple main reinforcing bars arranged circumferentially along and welded to the annular reinforcing bars, and spiral bars wrapped around and welded to the main reinforcing bars. Existing reinforcing cage forming and welding production lines include main reinforcing bar welding equipment, spiral bar welding equipment, automatic main reinforcing bar feeding equipment, and automatic spiral bar feeding equipment.

[0003] When welding the main ribs onto the annular reinforcing ribs, the operator needs to manually inspect the main ribs to check their straightness. Then, the main ribs that meet the requirements are placed on the material platform of the automatic main rib feeding device. Finally, the automatic main rib feeding device feeds the main ribs, and the main rib welding device welds the main ribs onto the annular reinforcing ribs.

[0004] Because the straightness of the main reinforcement bars needs to be checked manually before placing them on the material platform, the labor intensity of the operators is high. Summary of the Invention

[0005] To reduce the labor intensity of operators, this application provides an intelligent CNC steel cage forming and welding production line.

[0006] The intelligent CNC rebar cage forming and welding production line provided in this application adopts the following technical solution:

[0007] A smart CNC steel cage forming and welding production line includes an automatic main bar feeding device located on one side of the main bar welding device. The automatic main bar feeding device includes a material platform and a feeding robot. The automatic feeding device also includes an inclined plate connected to the surface of the material platform, and the inclined plate is inclined upward in the direction away from the material platform.

[0008] A detection bucket is fixed on the lower surface of the inclined plate. A through hole communicating with the detection bucket is provided on the inclined plate. The detection bucket includes two side plates that are slidably connected to the inclined plate and a bucket body located between the two side plates. A limit spring is also fixedly connected to the side plate. The limit spring is fixed to the inclined plate so that the side plate abuts against the bucket body.

[0009] The detection bucket is equipped with fixing components at both ends to fix the two ends of the main rib;

[0010] An mounting plate is slidably connected in the bucket body between two fixed components. The mounting plate slides along the length of the bucket body. A semi-annular detection ring plate is slidably connected on the mounting plate. The detection ring plate slides along the width of the bucket body. Each side plate is in contact with the detection ring plate.

[0011] The bucket body is equipped with a drive assembly for moving the mounting plate.

[0012] By adopting the above technical solution, in the initial state, the mounting plate is located at one end of the detection hopper, and the two side plates limit the detection ring plate, so that the axis of the detection ring plate is located in the middle of the detection hopper; when the straightness of the main rib needs to be detected, the main rib is placed on the inclined plate, and the main rib rolls along the inclined plate and falls into the detection hopper. At this time, the main rib is located in the detection ring plate, and the inner ring wall of the detection ring plate contacts the side wall of the main rib; then the fixing assembly fixes both ends of the main rib, and then the drive assembly is started. The drive assembly works to move the mounting plate to the other end of the detection hopper, while the main rib guides the detection ring plate. When the main rib is misaligned, the main rib drives the detection ring plate to move along the width of the detection bucket, thereby causing the detection ring plate to push the corresponding side plate to move. The operator can determine whether the main rib meets the usage requirements by observing the position of the side plate. After the inspection is completed, the drive assembly is activated, causing the mounting plate and the detection ring plate to move back to their initial positions. At the same time, the limit spring returns to its original deformation and pushes the side plate and the detection ring plate to move. When the limit spring and the mounting plate return to their initial state, the detection ring plate also returns to its initial position. This reduces the need for operators to manually inspect the main rib and lowers the labor intensity of the operators.

[0013] Optionally, the fixing assembly includes a first support rod and a second support rod that are slidably connected to the bucket body. The first support rod and the second support rod slide along the width direction of the bucket body. The fixing assembly also includes a power component that drives the first support rod and the second support rod to move.

[0014] By adopting the above technical solution, when the main rib enters the testing bucket, the main rib falls between the first support rod and the second support rod. Then, the power component works to move the first support rod and the second support rod closer to each other until both the first support rod and the second support rod abut against the main rib. The first support rod and the second support rod cooperate to fix the main rib.

[0015] Optionally, the power component includes a receiving plate located in the bucket body and sliding along the height direction of the bucket body. Several support springs are fixedly connected to the receiving plate, and the lower ends of the support springs are fixedly connected to the bucket body. The receiving plate has a strip-shaped hole for inserting a first support rod and a second support rod. Both the first support rod and the second support rod are hinged with a drive rod, which is hinged to the receiving plate. The two drive rods gradually tilt from bottom to top in a direction away from each other.

[0016] By adopting the above technical solution, when the main rib falls onto the receiving plate, the main rib presses the receiving plate downwards, simultaneously compressing the support spring. The receiving plate moves and drives the upper end of the drive rod downwards, causing the drive rod to rotate. The lower end of the drive rod moves closer to the center of the detection bucket, causing the first and second support rods to move closer to each other. When the main rib is removed from the receiving plate, the support spring returns to its original deformation and pushes the receiving plate upwards. The receiving plate moves and drives the drive rod, causing the first and second support rods to move away from each other. When the support spring returns to its initial state, the first and second support rods reset.

[0017] Optionally, the mounting plate is slidably connected to the upper surface of the receiving plate, and the driving assembly includes two limiting plates fixedly connected to the receiving plate, each limiting plate contacting a corresponding side plate. The mounting plate is located between the two limiting plates, and a lead screw is threadedly connected to the mounting plate, the lead screw passing through the mounting plate. A drive motor for driving the lead screw to rotate is also mounted on the mounting plate.

[0018] By adopting the above technical solution, when it is necessary to move the mounting plate along the length of the detection bucket, the drive motor is started, the drive motor drives the lead screw to rotate, and the lead screw cooperates with the limit plate, so that the mounting plate can drive the limit ring plate to move along the length of the detection bucket.

[0019] Optionally, the inclined plate is provided with a material distribution component for controlling the main ribs to enter the detection hopper.

[0020] By adopting the above technical solution, operators can place multiple main ribs on the inclined plate, and the material distribution component controls the main ribs to enter the detection hopper one by one, reducing the need for operators to manually feed them one by one.

[0021] Optionally, the material distribution assembly includes a base plate hinged to the upper surface of the inclined plate, and a baffle plate fixedly connected to the base plate vertically. The base plate and the baffle plate are located on the side of the detection hopper away from the material platform. The width of the base plate is less than the sum of the diameters of the two main ribs. A material distribution motor for driving the base plate to rotate is also installed on the inclined plate.

[0022] By adopting the above technical solution, in the initial state, the bottom plate and the inclined plate are in contact, the baffle is perpendicular to the inclined plate, and the main ribs are evenly distributed on the inclined plate. One of the main ribs is located on the bottom plate and is in contact with the baffle. When it is necessary to push the main rib into the detection hopper, the feeding motor is started. The feeding motor makes the baffle rotate downward and the bottom plate rotate upward. When the baffle and the inclined plate are in contact, the bottom plate is perpendicular to the inclined plate. At this time, the main rib between the baffle and the bottom plate falls into the detection hopper. When the bottom plate rotates, it blocks the main rib on the inclined plate, reducing the number of main ribs falling into the detection hopper at the same time.

[0023] After the main ribs on the bottom plate and the baffle fall into the detection hopper, the material distribution motor is started, causing the baffle and the bottom plate to rotate to the initial state. At this time, the remaining main ribs slide under the action of the inclined plate, causing one of the main ribs to slide onto the bottom plate.

[0024] Optionally, the inclined plate is also provided with an alarm component, which includes a ranging sensor located on the side of the side plate away from the other side plate. The ranging sensor is mounted on the inclined plate. The inclined plate is also equipped with a controller that is electrically connected to the ranging sensor. An alarm is also mounted on the inclined plate and is electrically connected to the controller.

[0025] By adopting the above technical solution, when the main rib is defective, the detection ring plate moves along the main rib, and the main rib causes the detection ring plate to push the corresponding side plate to move. When the side plate moves into the detection range of the distance sensor, the distance sensor transmits a signal to the controller, and the controller controls the alarm to work, thereby reminding the staff to take the defective main rib out of the detection bucket.

[0026] Optionally, a reset component is provided below the receiving plate in the bucket body. The reset component includes a cylinder fixed on the bottom wall of the bucket body. A push plate is fixedly connected to the top of the telescopic end of the cylinder. A through hole is provided on the receiving plate for the push plate to pass through.

[0027] By adopting the above technical solution, when the main rib needs to be removed from the detection bucket, the cylinder is instructed to push the push plate and the main rib upward. At the same time, the support spring restores its deformation and pushes the receiving plate upward, thereby causing the drive rod to rotate and the first support rod and the second support rod to move away from each other, thus releasing the fixation of the main rib.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting up a detection bucket, side plate, limit spring, mounting plate, detection ring plate, fixing components, and drive components, the labor intensity of operators is reduced;

[0030] 2. By setting up a receiving plate, supporting spring, driving rod, first support rod, and second support rod, the two ends of the main reinforcement can be automatically fixed;

[0031] 3. By setting up cylinders and push plates, the first and second support rods can be released from fixing the main reinforcement. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses an intelligent CNC rebar cage forming and welding production line. It includes a main rebar welding device and an automatic main rebar feeding device located on one side of the main rebar welding device, and also includes a spiral rebar welding device and an automatic spiral rebar feeding device; see reference... Figure 1 The main rib automatic feeding device includes a material platform 1 and a feeding robot arm installed on the material platform 1.

[0040] Reference Figure 1 and Figure 2 A frame 2 is provided on the side of the material platform 1 away from the main rib welding device. The length direction of the frame 2 and the material platform 1 is the same. The frame 2 includes an inclined plate 21 connected to the upper surface of the material platform 1. The inclined plate 21 gradually tilts upward in the direction away from the material platform 1. A discharge hole 211 is provided on the side of the upper surface of the inclined plate 21 close to the material platform 1. The length direction of the discharge hole 211 is set along the length direction of the material platform 1. A detection hopper 3 is provided below the inclined plate 21. The top of the detection hopper 3 is connected to the discharge hole 211.

[0041] Reference Figure 2 and Figure 3The detection bucket 3 includes a bucket body 31 fixedly connected to the lower surface of the inclined plate 21. The length direction of the bucket body 31 is consistent with the length direction of the inclined plate 21. One side of each of the two long sides of the bucket body 31 is open. The bucket body 31 is inclined. The inner bottom wall of the bucket body 31 is parallel to the upper surface of the inclined plate 21. The detection bucket 3 also includes two side plates 32 for sealing the opening of the bucket body 31. The bucket body 31 is located between the two side plates 32. The side plates 32 are perpendicular to the upper surface of the inclined plate 21.

[0042] Several sliders 321 are fixedly connected to the upper surface of the side plate 32. The lower surface of the inclined plate 21 is provided with a groove 212 corresponding to the sliders 321. The length direction of the groove 212 is set along the width direction of the frame 2. Each slider 321 is slidably inserted into the corresponding groove 212. The slider 321 and the groove 212 cooperate to make the baffle 42 and the inclined plate 21 slide together. A limiting spring 33 is fixedly connected to the inner wall of the end of the groove 212 away from the bucket body 31. The limiting spring 33 is fixedly connected to the slider 321. When the limiting spring 33 is in a compressed state, the side plate 32 abuts against the bucket body 31, thereby blocking the opening on the side of the bucket body 31.

[0043] Reference Figure 2 and Figure 3 When inspecting the main ribs, the main ribs need to be placed into the inspection hopper 3 one by one for inspection. The inclined plate 21 is also provided with a material distribution component 4 to control the main ribs to enter the inspection hopper 3. The material distribution component 4 includes a bottom plate 41 hinged to the upper surface of the inclined plate 21. The bottom plate 41 is adjacent to the discharge hole 211. The bottom plate 41 is located on the side of the discharge hole 211 away from the material platform 1. The length direction of the bottom plate 41 is set along the length direction of the inclined plate 21. The rotation axis of the bottom plate 41 is also set along the length direction of the inclined plate 21. The width of the bottom plate 41 is the diameter of the main rib. The side wall of the bottom plate 41 away from the discharge hole 211 gradually tilts from top to bottom in the direction away from the discharge hole 211.

[0044] A baffle 42 is vertically fixedly connected to the base plate 41. The length direction of the baffle 42 is set along the length direction of the base plate 41. A material distribution motor 43 is also fixedly connected to the frame 2. The output shaft of the material distribution motor 43 is coaxial with the hinge shaft of the base plate 41, and the output shaft of the material distribution motor 43 is fixed with the hinge shaft of the base plate 41. In the initial state, the base plate 41 is in contact with the upper surface of the frame 2, the baffle 42 is perpendicular to the inclined plate 21, a main rib is located on the base plate 41, and the main rib on the base plate 41 is in contact with the baffle 42.

[0045] Reference Figure 2 and Figure 3The bucket body 31 is provided with fixing components 5 at both ends of the bucket body 31 to fix the main ribs. The fixing components 5 include a first support rod 51 and a second support rod 52 that are slidably connected to the bottom wall of the bucket body 31. The first support rod 51 and the second support rod 52 are both perpendicular to the bottom wall of the bucket body 31. The first support rod 51 and the second support rod 52 are arranged in sequence toward the material platform 1. The upper end of the second support rod 52 is higher than the upper end of the first support rod 51.

[0046] The lower ends of the first support rod 51 and the second support rod 52 are both fixedly connected to T-shaped connecting blocks 53. A connecting groove 311 is provided on the inner bottom wall of the bucket body 31. The length direction of the connecting groove 311 is set along the width direction of the frame 2. The two connecting blocks 53 are simultaneously slidably inserted into the connecting groove 311. The connecting blocks 53 and the connecting groove 311 cooperate to make the first support rod 51 and the second support rod 52 slidably connected to the bucket body 31.

[0047] The fixing assembly 5 also includes a power component 54 for driving the first support rod 51 and the second support rod 52 to move. The power component 54 includes a receiving plate 541 located in the bucket body 31. The circumferential sidewalls of the receiving plate 541 are in contact with the corresponding sidewalls of the detection bucket 3. The upper surface of the receiving plate 541 is parallel to the upper surface of the inclined plate 21. The receiving plate 541 has a strip hole 5411 that penetrates the receiving plate 541 at the position corresponding to the first support rod 51 and the second support rod 52. The length direction of the strip hole 5411 is set along the width direction of the frame 2. The first support rod 51 and the second support rod 52 are both inserted through the strip hole 5411.

[0048] The power component 54 also includes a plurality of support springs 542 fixedly connected to the lower surface of the receiving plate 541. The plurality of support springs 542 are evenly distributed on the receiving plate 541. The lower end of the support spring 542 is fixedly connected to the inner bottom wall of the bucket body 31. The support spring 542 creates a gap between the lower surface of the receiving plate 541 and the inner bottom wall of the bucket body 31. Both the first support rod 51 and the second support rod 52 are hinged with drive rods 543. The upper end of the drive rod 543 is hinged to the lower surface of the receiving plate 541. The two corresponding drive rods 543 gradually tilt away from each other from bottom to top.

[0049] Reference Figure 2 and Figure 4A detection component 6 for detecting the straightness of the main reinforcement is also provided between the two first support rods 51. The detection component 6 includes two mounting plates 61 disposed on the upper surface of the support plate 541. The two mounting plates 61 are distributed at both ends of the support plate 541. One of the mounting plates 61 is fixedly connected to the support plate 541. The length direction of the mounting plate 61 is set along the width direction of the support plate 541. A semi-annular detection ring plate 62 is provided on the upper surface of the support plate 541. The axial direction of the detection ring plate 62 is set along the length direction of the support plate 541. The opening of the detection ring plate 62 faces upward, and the inner diameter of the detection ring plate 62 is consistent with the diameter of the main reinforcement. Both side plates 32 are in contact with the outer side wall of the detection ring plate 62.

[0050] A sliding groove 611 is provided on the upper surface of the mounting plate 61. The length direction of the sliding groove 611 is set along the length direction of the mounting plate 61. A sliding block 621 is slidably inserted into the sliding groove 611. The outer wall of the detection ring plate 62 is fixed to the sliding block 621. The sliding block 621 cooperates with the sliding groove 611 to enable the detection ring plate 62 to slide along the length direction of the receiving plate 541.

[0051] Reference Figure 2 and Figure 3 The receiving plate 541 is also provided with a driving assembly 7 for driving the mounting plate 61 to move along the length direction of the receiving plate 541. The driving assembly 7 includes two limiting plates 71 that are vertically fixedly connected to the upper surface of the receiving plate 541. The length direction of the limiting plates 71 is set along the length direction of the receiving plate 541. The mounting plate 61 is located between the two limiting plates 71 and is in contact with the two limiting plates 71.

[0052] The drive assembly 7 also includes a lead screw 72 rotatably connected to the receiving plate 541. The length direction of the lead screw 72 is consistent with the length direction of the receiving plate 541. The lead screw 72 passes through two mounting plates 61, wherein the mounting plate 61 sliding along the receiving plate 541 is threadedly connected to the lead screw 72. A drive motor 73 is provided on the receiving plate 541 at one end of the lead screw 72. The output shaft of the drive motor 73 is coaxial with the lead screw 72, and the end faces of the drive motor 73 and the lead screw 72 that are close to each other are fixed. The highest point of the drive motor 73 is lower than the upper surface of the mounting plate 61.

[0053] Reference Figure 3 and Figure 5 The bucket body 31 is also provided with a reset component 8 that pushes the main rib that has been tested onto the material platform 1. The reset component 8 includes a cylinder 81 fixedly connected to the inner bottom wall of the bucket body 31. A push plate 82 is fixedly connected to the upper end of the telescopic rod of the cylinder 81. The push plate 82 is parallel to the inclined plate 21. The cylinder 81 and the push plate 82 are both located on one side of the lead screw 72. A through hole is opened on the receiving plate 541 for the push plate 82 to pass through. When the support spring 542 is in a fully compressed state, there is still a gap between the push plate 82 and the receiving plate 541.

[0054] Reference Figure 2 and Figure 3 When the detection component 6 detects a defective product, an alarm component 9 is also provided on the inclined plate 21 to facilitate reminding the operator to remove the defective product. The alarm component 9 includes two distance sensors 91 installed on the inclined plate 21, and two side plates 32 are located between the two distance sensors 91. The alarm component 9 also includes a controller 93 installed on the inclined plate 21. The distance sensors 91 are electrically connected to the controller 93. An alarm 92 is also installed on the inclined plate 21 and is electrically connected to the controller 93. The cylinder 81, the drive motor 73, and the material distribution motor 43 are all electrically connected to the controller 93.

[0055] Before testing the main reinforcement, the operator lays multiple main reinforcements on the inclined plate 21, with one main reinforcement located on the bottom plate 41. At this time, the main reinforcement has not fallen into the detection ring plate 62, the support spring 542 is in the initial state, the distance between the first support rod 51 and the second support rod 52 is greater than the diameter of the main reinforcement, and the two side plates 32 limit the detection ring plate 62 so that the axis of the detection ring plate 62 is located in the middle of the receiving plate 541. The side plates 32 abut against the bucket body 31 under the action of the limiting spring 33. At this time, the side plates 32 are outside the detection range of the distance measuring sensor 91.

[0056] When the main ribs are being tested, the controller 93 controls the dispensing motor 43 to work, causing the dispensing motor 43 to drive the base plate 41, the baffle 42, and the main ribs on the base plate 41 to rotate, so that the base plate 41 rotates to fit against the inclined plate 21. At this time, the baffle 42 rotates to be perpendicular to the inclined plate 21. At this time, the main ribs between the base plate 41 and the baffle 42 fall into the testing hopper 3 through the discharge hole 211. During the rotation of the base plate 41 and the baffle 42, the baffle 42 limits the subsequent main ribs, reducing the occurrence of multiple main ribs falling into the testing hopper 3 at the same time.

[0057] When the baffle 42 contacts the inclined plate 21, the controller 93 controls the dispensing motor 43 to work, causing the baffle 42 to rotate towards the inclined plate 21. When the baffle 42 rotates, it pushes the main rib in contact with it to move. When the baffle 42 moves to fit against the inclined plate 21, the main rib near the baffle 42 moves towards the baffle 42 under the action of the inclined plate 21. At this time, the controller 93 controls the dispensing motor 43 to stop working for a period of time to provide time for the detection component 6 and the reset component 8 to work. After a period of time, the controller 93 controls the dispensing motor 43 to work again, thereby pushing the main rib into the detection hopper 3.

[0058] After the main reinforcement bar falls into the detection bucket 3, the second support rod 52 limits the main reinforcement bar, causing it to fall into the detection ring plate 62. The inner ring wall of the detection ring plate 62 contacts the side wall of the main reinforcement bar. At the same time, the reinforcement bar moves the detection ring plate 62, the mounting plate 61, and the receiving plate 541 downwards. As the receiving plate 541 moves, it also compresses the support spring 542. The receiving plate 541 drives the upper end of the drive rod 543 to move downwards, causing the lower end of the drive rod 543 to move towards the middle of the bucket body 31. This causes the first support rod 51 and the second support rod 52 to move closer to each other until the first support rod 51 and the second support rod 52 cooperate to clamp and fix the end of the main reinforcement bar.

[0059] After a period of time, the controller 93 controls the drive motor 73 to work, and the drive motor 73 drives the lead screw 72 to rotate. The lead screw 72 cooperates with the limit plate 71 to move the receiving plate 541 and the detection ring plate 62 closer to the other end of the receiving plate 541. When the receiving plate 541 and the detection ring plate 62 move, the main rib guides the detection ring plate 62, causing the detection ring plate 62 and the sliding block 621 to move, thereby causing the detection ring plate 62 to move along the width direction of the bucket body 31. The movement of the detection ring plate 62 pushes the corresponding side plate 32 to move. At the same time as the side plate 32 moves, it further compresses the limit spring 33.

[0060] When the main reinforcement meets the usage requirements, after the detection ring plate 62 pushes the side plate 32 to move, the side plate 32 is still outside the detection range of the distance sensor 91; when the main reinforcement does not meet the usage requirements, after the detection ring plate 62 pushes the side plate 32 to move, the side plate 32 is within the detection range of the distance sensor 91. At this time, the distance sensor 91 transmits a signal to the controller 93, and after receiving the signal, the controller 93 controls the alarm 92 to sound an alarm.

[0061] Simultaneously with the alarm triggered by controller 93, controller 93 reverses the rotation shaft of drive motor 73, causing lead screw 72 to reset the receiving plate 541. At the same time, controller 93 controls cylinder 81 to operate, causing cylinder 81 to push push plate 82 upward. As push plate 82 moves, it pushes the main rib upward. While the main rib moves, support spring 542 recovers its deformation and pushes receiving plate 541 upward. The movement of receiving plate 541 causes the corresponding end of drive rod 543 to move, thereby causing drive rod 543 to rotate. The lower end of drive rod 543 moves towards the edge of bucket body 31, causing the first support rod 51 and the second support rod 52 to move away from each other. When the telescopic rod of cylinder 81 stops moving, both the first support rod 51 and the second support rod 52 are at a distance from the main rib. At this time, the main rib is still located in the detection bucket 3, and the operator can remove the main rib.

[0062] After the main rib is removed, the support spring 542 continues to deform and pushes the receiving plate 541 upward. When the support spring 542 returns to its initial state, the receiving plate 541, the first support rod 51, and the second support rod 52 all return to their initial positions. At the same time, the limiting spring 33 restores its deformation and pushes the side plate 32 to move. The side plate 32 moves and pushes the detection ring plate 62 to move. When the limiting spring 33 returns to its initial state, both side plates 32 abut against the bucket body 31. The side plates 32 limit the detection ring plate 62, so that the axis of the detection ring plate 62 is still located in the middle of the receiving plate 541.

[0063] After a period of time, the controller 93 controls the cylinder 81 to work, causing the push plate 82 to reset; when the material distribution assembly 4 pushes the next main bar into the detection hopper 3, the receiving plate 541 moves to fix the first support rod 51 and the second support rod 52 to the bar, and the controller 93 controls the drive motor 73 to work, thereby detecting the main bar; after the drive motor 73 has been working for a period of time, the mounting plate 61 and the detection ring plate 62 move to the other end of the receiving plate 541, and the alarm 92 is not triggered, indicating that the detected main bar is qualified. The controller 93 controls the cylinder 81 to work, causing the push plate 82 to push the main bar out of the detection hopper 3.

[0064] When the main rib is outside the detection hopper 3, it falls onto the inclined plate 21 along the inclined push plate 82, and then falls onto the material platform 1. Finally, the controller 93 controls the cylinder 81 and the drive motor 73 to reset the receiving plate 541, drive rod 543, first support rod 51, second support rod 52, mounting plate 61, detection ring plate 62, and side plate 32. This reduces the need for manual inspection of the straightness of the main rib and lowers the labor intensity of the operators.

[0065] The implementation principle of an intelligent CNC steel cage forming and welding production line according to an embodiment of this application is as follows: the operator places multiple main steel bars on the inclined plate 21, and the controller 93 controls the material distribution motor 43 to work, thereby pushing the main steel bars into the detection hopper 3 one by one; when the main steel bars enter the detection hopper 3, the main steel bars move by pressing the receiving plate 541, thereby fixing the main steel bars with the first support rod 51 and the second support rod 52. At the same time, the controller 93 controls the drive motor 73 to work, so that the detection ring plate 62 moves along the main steel bars.

[0066] When the detection ring plate 62 pushes the corresponding side plate 32 to the point where it triggers the alarm 92, the controller 93 controls the drive motor 73 to stop working and controls the cylinder 81 to drive the push plate 82 to push the main rib upward. At this time, the operator removes the main rib. After a period of time, the controller 93 controls the cylinder 81 and the drive motor 73 to work, so that the detection ring plate 62 and the side plate 32 are reset. After the drive motor 73 has been working for a period of time, the detection ring plate 62 moves to the other end of the receiving plate 541, and the side plate 32 does not trigger the alarm 92. At this time, the controller 93 controls the drive motor 73 to stop working and controls the cylinder 81 to work, so that the push plate 82 pushes the main rib to move outside the detection hopper 3, so that the main rib falls onto the inclined plate 21 and rolls onto the material platform 1.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
