Description

Technical Field

[0001] This invention relates to the field of welding equipment, and more particularly to a welding method for a poultry egg conveyor chain. Background Technology

[0002] The poultry egg conveyor chain consists of two chains and crossbars. The chains are made up of interlocking horizontal and vertical links. The two ends of the crossbars are welded to either the horizontal or vertical links of the two chains. Because the tops of the horizontal and vertical links are at different heights, to ensure consistent height of all crossbars, they are divided into straight bars and zigzag bars. Both ends of the zigzag bars have angled bends. The ends of the two angled bends of the zigzag bars are fixed to the tops of the horizontal links of the two chains, and the middle section of the zigzag bar is arched vertically (i.e., the zigzag bar stands upright). The two ends of the straight bars are welded to the tops of the vertical links, thus ensuring that the straight bars and zigzag bars are at the same height.

[0003] During the welding of the zigzag rod, it is necessary to first stand the zigzag rod upright, and then weld the ends of the two obliquely bent sections of the zigzag rod to the top side of the horizontal chain links of the two chains. The process of "standing the zigzag rod upright" has a low degree of automation, resulting in low overall efficiency of the poultry egg conveyor chain production process. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a method for welding a poultry egg conveyor chain, which can efficiently erect the zigzag rod so as to weld the zigzag rod to the top side of the horizontal link of the two chains.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A method for welding a poultry egg conveyor chain includes the following steps:

[0007] Unloading steps: The unloading rack stores the folding rods, and the two ends of the folding rods are equipped with slanted bending sections. The unloading rack tilts downward from back to front. The unloading rack releases one folding rod at a time, and the released folding rod falls into two gripper mechanisms.

[0008] Initial calibration steps: The vertical push cylinder drives the pusher to extend outward, so that the arc-shaped edge of the vertical end of the pusher pushes against the inclined bending section. When the pusher extends outward, it pushes the bending section to the vertical position. When the pusher pushes against the bending section, it will cause the bending rod to move a small distance away from the vertical push cylinder in the lateral direction.

[0009] Secondary calibration step: The piston rods of the two lateral positioning cylinders extend outwards simultaneously, respectively contacting the two ends of the broken line rod that has completed the initial calibration step and is already in an upright position, thereby moving the broken line rod laterally to a suitable position;

[0010] Clamping steps: Two gripper mechanisms clamp the folding rod;

[0011] Welding steps: The welding head moves down to contact both ends of the inclined bend section, so that the welding head, the end of the inclined bend section, the inner ring of the horizontal chain link, and the welding station block form part of a closed loop. Then, the closed loop is energized, and the current flows through the end of the inclined bend section and the inner ring of the horizontal chain link, generating high temperature, which melts and joins the two, thus achieving welding.

[0012] Specifically, in the unloading step, the base is rotatably provided with a rotating rod, which is arranged in the horizontal direction. The rotating rod is coaxially fixed to a limiting disc, and the edge of the limiting disc is provided with a release notch. The circular edge of the limiting disc is used to abut against the broken bar located at the lowest point in the unloading frame.

[0013] Specifically, in the unloading step, two gripper mechanisms are used to receive the broken wire rod falling from the unloading frame. When the broken wire rod falls to the gripper mechanism, the oblique bend of one end of the broken wire rod enters the limiting block on that side and abuts against the groove wall of the limiting groove at an angle.

[0014] Specifically, in the initial calibration step, when the piston rod of the vertical push cylinder completes its extension stroke, the end arc surface of the push plate abuts against the inclined bending section, keeping the folded rod upright.

[0015] Specifically, in the welding step, the welding station block is made of metal, and the welding head can be moved down to contact the end of the inclined bend section to weld the end of the inclined bend section.

[0016] Specifically, before the material unloading step, there is a chain conveying step: both sides of the base are provided with guide grooves, which are set longitudinally and located on the front or rear side of the welding station block. Each sprocket rotates in coordination, causing the two chains to move from back to front. The guide grooves allow the chains to pass through, so as to guide and limit the chains, and make the inner ring section of the horizontal chain link pass slightly over the top surface of the welding station block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] As the pusher completes its extension stroke, it pushes the inclined bending section to an upright position, causing the folding rod to move a short distance laterally away from the upright push cylinder. This process is called the initial calibration. After the initial calibration is completed, the piston rods of the two lateral positioning cylinders extend simultaneously, contacting the two ends of the folding rod, which has now completed the initial calibration and is in an upright position. This moves the folding rod laterally to the appropriate position—the ends of the two inclined bending sections are respectively located on the top side of the inner ring of the horizontal chain links of the two chains. This process is called the secondary calibration. The initial and secondary calibrations are seamlessly connected, efficiently and conveniently erecting the folding rod and achieving its lateral positioning, thereby improving the production efficiency of the egg conveyor chain.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] A method for welding a poultry egg conveyor chain includes the following steps:

[0030] Unloading steps: The unloading rack 1 stores the folded bar 11. The two ends of the folded bar 11 are provided with inclined bending sections 111. The unloading rack 1 tilts downward from back to front. The unloading rack 1 releases one folded bar 11 at a time. The released folded bar 11 falls into two gripper mechanisms 4.

[0031] Initial calibration steps: The vertical push cylinder 5 drives the push plate 51 to extend outward, so that the arc-shaped edge of the vertical end of the push plate 51 pushes against the inclined bending section 111 which is in an inclined state. When the extension stroke of the push plate 51 ends, the push plate 51 pushes the inclined bending section 111 to the vertical state. When the push plate 51 pushes against the inclined bending section 111, it will cause the bending rod 11 to move a small distance away from the horizontal direction of the vertical push cylinder 5.

[0032] Secondary calibration step: The piston rods of the two lateral positioning cylinders 15 extend outwards simultaneously and abut against the two ends of the folded rod 11, which has already completed the first calibration step and is in an upright state, thereby moving the folded rod 11 laterally to a suitable position.

[0033] Clamping steps: The two gripper mechanisms 4 clamp the folding rod 11;

[0034] Welding steps: The welding head 13 moves down to contact both ends of the inclined bending section 111, so that the welding head 13, the end of the inclined bending section 111, the inner ring of the horizontal chain link of the chain 3 and the welding station block 12 form part of a closed loop. Then, the closed loop is energized, and the current flows through the end of the inclined bending section 111 and the inner ring of the horizontal chain link of the chain 3, generating high temperature, so that the two melt and join together to achieve welding.

[0035] Specifically, in the unloading step, the base is rotatably equipped with a rotating rod 6, which is arranged laterally. A limiting disc 61 is coaxially fixed to the rotating rod 6. The edge of the limiting disc 61 is provided with a release notch 62. The circular edge of the limiting disc 61 is used to abut against the broken bar 11 located at the lowest point in the unloading frame 1. Specifically, a connecting disc 63 is fixed to the end of the rotating rod 6. The connecting disc 63 has an elongated hole 64. The base is equipped with a swing drive cylinder 7. The piston rod of the swing drive cylinder 7 is fixed with a pin 71, which is slidably disposed in the elongated hole 64.

[0036] Specifically, in the unloading step, two gripper mechanisms 4 are used to receive the broken wire rod 11 falling from the unloading frame 1. When the broken wire rod 11 falls to the gripper mechanism 4, the obliquely bent section 111 of one end of the broken wire rod 11 falls into the limiting block 14 on that side and obliquely abuts against the groove wall of the limiting groove 141.

[0037] Specifically, in the initial calibration step, when the piston rod of the vertical push cylinder 5 completes its extension stroke, the end arc surface of the push plate 51 abuts against the inclined bending section 111, keeping the folded rod 11 upright.

[0038] Specifically, in the welding step, the welding station block 12 is made of metal, and the welding head 13 can be moved down to contact the end of the inclined bending section 111 to weld the end of the inclined bending section 111.

[0039] Specifically, before the material unloading step, there is a chain 3 conveying step: both sides of the base are provided with guide grooves 16, which are arranged longitudinally and located in front of or behind the welding station block 12. Each sprocket 2 rotates in coordination, so that the two chains 3 move from back to front. The guide grooves 16 allow the chains 3 to pass through, so as to guide and limit the chains 3, and so that the inner ring of the horizontal chain link of the chain 3 passes slightly over the top surface of the welding station block 12.

[0040] The egg conveyor chain welding method of the present invention is as follows:

[0041] Each sprocket 2 rotates in coordination, causing the two chains 3 to move from back to front. The guide groove 16 allows the chains 3 to pass through, guiding and limiting their movement. The guide groove 16 is located on the front or rear side of the welding station block 12, allowing the inner ring of the horizontal link of the chain 3 to slightly pass over the top surface of the welding station block 12 (e.g., ...). Figure 7 (As shown).

[0042] The circular edge of the limiting disc 61 is used to abut against the lowest-positioned folded bar 11 in the unloading rack 1. When the rotating rod 6 rotates until the release notch 62 of the limiting disc 61 aligns with the lowest-positioned folded bar 11 in the unloading rack 1, the folded bar 11 enters the release notch 62 and then falls from the unloading rack 1 into the two gripper mechanisms 4, where it is supported (at this time, the folded bar 11 is not clamped). Subsequently, the circular edge of the limiting disc 61 continues to abut against the folded bar 11 located at the lowest position in the unloading rack 1.

[0043] Since the unloading rack 1 is laterally close to the side where the vertical push cylinder 5 is located, when the aforementioned folding rod 11 falls from the unloading rack 1 into the two gripper mechanisms 4, the obliquely bent section 111 of the folding rod 11 near the vertical push cylinder 5 will fall into the limiting block 14 located on that side, and rely on the vertical wall of its limiting groove 141, so that the obliquely bent section 111 is in an inclined state (e.g., Figure 4 , Figure 5 (As shown).

[0044] Subsequently, the vertical push cylinder 5 drives the pusher 51 to extend outward, causing the arc-shaped edge of the vertical end of the pusher 51 to push against the inclined bent section 111, which is in an inclined state. At the end of the extension stroke of the pusher 51, the pusher 51 pushes the inclined bent section 111 into an upright state (e.g., Figure 6 (As shown). Because the inclined section 111 is tilted, when the pusher 51 pushes the inclined section 111, it will cause the folding rod 11 to move a small distance in the lateral direction away from the vertical push cylinder 5. The above process is called the initial calibration.

[0045] After the initial calibration is completed, the piston rods of the two lateral positioning cylinders 15 extend outward simultaneously, respectively contacting the two ends of the folded rod 11, which has already completed the initial calibration and is in an upright position. This causes the folded rod 11 to move laterally to a suitable position—the ends of the two obliquely bent sections 111 are respectively located on the top side of the inner ring section of the horizontal links of the two chains 3 (e.g., Figure 7 As shown in the figure, the above process is called secondary calibration.

[0046] After the above secondary calibration is completed, the two gripper mechanisms 4 immediately clamp the bending rod 11, and then the welding head 13 moves down to contact both ends of the inclined bending section 111 (combined with...). Figure 1 , Figure 7 This causes the welding head 13, the end of the inclined bending section 111, the inner ring of the horizontal chain link 3, and the welding station block 12 to form part of a closed loop. Then, the closed loop is energized, and the current flows through the end of the inclined bending section 111 and the inner ring of the horizontal chain link 3, generating high temperature, which melts and joins the two to achieve welding.

[0047] As the pusher 51 completes its extension stroke, it pushes the obliquely bent section 111 to an upright position (e.g., Figure 6 (As shown), and will drive the folding rod 11 to move a short distance laterally away from the vertical pushing cylinder 5. This process is called the initial calibration. After the initial calibration is completed, the piston rods of the two lateral positioning cylinders 15 extend outward simultaneously, respectively abutting the two ends of the folding rod 11, which has completed the initial calibration and is now in an upright position, thereby moving the folding rod 11 laterally to a suitable position—the ends of the two obliquely bent sections 111 are respectively located on the top side of the inner ring section of the horizontal chain links of the two chains 3 (as shown). Figure 7 As shown in the diagram, the above process is called secondary calibration. The primary and secondary calibrations are seamlessly connected, enabling the folding rod 11 to be erected efficiently and conveniently, and achieving its lateral positioning, thereby improving the production efficiency of the poultry egg conveyor chain.

[0048] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
