Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding line. Background Technology

[0002] During the production process, it is often necessary to weld the first and second bars to form a product. This is typically done using a welding line. In existing technology, the welding line relies on manual loading of the first bar so that the welding mechanism can weld it to the second bar, resulting in low welding efficiency. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a welding line that can improve welding efficiency.

[0004] This invention provides a welding line, which includes a pushing mechanism, a feeding mechanism, and a welding mechanism. The pushing mechanism includes a pushing drive and a pushing component. The pushing drive is connected to the pushing component and can drive the pushing component to push a first bar from the discharge position to the welding position, so that the first bar abuts against a second bar. The feeding mechanism includes a housing and a carrier. The housing stores the first bar, and the carrier abuts against the first bar. The carrier is movably connected to the housing. When the carrier moves relative to the housing, it can transfer the first bar inside the housing to the discharge position. The welding mechanism is used to weld the first bar and the second bar at the welding position to form a product.

[0005] The welding line provided by the embodiments of the present invention has at least the following beneficial effects: The carrier can sequentially transfer multiple first bars inside the box to the discharge position. The pusher can drive the pusher to push the first bars at the discharge position to abut against the second bars at the welding position, so that the welding mechanism can weld the first bars and the second bars to form a product. This enables automatic feeding of the first bars and improves welding efficiency.

[0006] In one embodiment of this implementation, the welding line further includes a clamping mechanism. The clamping mechanism includes a first welding seat with a clamping groove extending through the first welding seat. When the carrier moves the first bar to the discharge position, the pusher can push the first bar into the clamping groove and make one end of the first bar extend from the side of the first welding seat away from the carrier so that the first bar abuts against the second bar.

[0007] In one embodiment of this implementation, the clamping mechanism further includes a second welding seat. The first welding seat and the second welding seat are arranged at intervals along a first direction. The second welding seat is located on the side of the first welding seat away from the carrier. The second welding seat is used to allow one end of the second bar to extend into the gap between the first welding seat and the second welding seat, so that the first bar and the second bar abut against each other within the gap.

[0008] In one embodiment of this implementation, the welding line further includes a first clamping block, a second clamping block, and a feeding drive assembly. Both the first clamping block and the second clamping block are provided with arc-shaped grooves. The first clamping block and the second clamping block are respectively connected to the feeding drive assembly. The feeding drive assembly can drive the first clamping block and the second clamping block to extend into the gap and move closer to each other, so that the two arc-shaped grooves form a positioning hole, and the hole wall of the positioning hole abuts against the outer peripheral wall of the first bar and the outer peripheral wall of the second bar respectively. The feeding drive assembly can also drive the first clamping block and the second clamping block to move to the feeding position.

[0009] In one embodiment of this implementation, a cooling channel is provided on the first clamping block, which is used for coolant to flow through the first clamping block.

[0010] In one embodiment of this implementation, the feeding mechanism further includes a movable plate and a limiting component. The movable plate is disposed on the box and surrounds the box to form a storage bin for storing the first bar stock. The movable plate can move relative to the box along the axial direction of the first bar stock and is fixed in relative position to the box by the limiting component.

[0011] In one embodiment of this implementation, the first solder pad and the second solder pad are movably connected along a second direction, which is perpendicular to the first direction. The first solder pad and the second solder pad are relatively movably connected along a third direction. The second solder pad and the first solder pad are rotatably connected about an axis parallel to the third direction, which is perpendicular to the first direction and the second direction.

[0012] In one embodiment of this implementation, the welding mechanism includes a first welding head and a second welding head. The first welding head is used to energize a first bar stock, and the second welding head is used to energize a second bar stock. The first welding head is connected to a first welding base so that it can move with the first welding base.

[0013] In one embodiment of this implementation, the box body has an outlet, and the support member has a protrusion. When the support member moves relative to the box body, the protrusion can push the first bar through the outlet, so as to change the relative position between multiple first bars in the storage bin.

[0014] In one embodiment of this implementation, the feeding mechanism includes a push ball, and the carrier has an installation groove. The push ball is rotatably engaged with the installation groove and is partially exposed outside the installation groove to form a protrusion.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0024] Please see Figures 1 to 2 , Figures 4 to 5 , Figure 1 This is a three-dimensional structural schematic diagram of the welding line 100 according to one embodiment of the present invention; Figure 2 yes Figure 1 A top view of the welding line 100; Figure 4 yes Figure 1 A schematic diagram of the pusher mechanism 10; Figure 5 yes Figure 1 A schematic diagram of the feeding mechanism 20 is shown. This embodiment of the invention provides a welding line 100, which includes a pushing mechanism 10, a feeding mechanism 20, and a welding mechanism 30. The pushing mechanism 10 includes a pushing drive 11 and a pushing component 12. The pushing drive 11 is connected to the pushing component 12 and can drive the pushing component 12 to push the first bar material from the discharge position to the welding position, so that the first bar material abuts against the second bar material. The feeding mechanism 20 includes a housing 21 and a carrier 22. The housing 21 is used to store the first bar material, and the carrier 22 is used to abut against the first bar material. The carrier 22 is movably connected to the housing 21. When the carrier 22 moves relative to the housing 21, it can transfer the first bar material in the housing 21 to the discharge position. The welding mechanism 30 is used to weld the first bar material and the second bar material located at the welding position to form a product.

[0025] Specifically, the pusher drive 11 is a linear drive with the drive direction parallel to the X direction. The pusher 12 is installed on the drive end of the pusher drive 11. A storage bin 26 is formed inside the housing 21. The storage bin 26 is used to stack multiple first bars with axes parallel to the X direction. An outlet 27 is opened on one side of the housing 21 along the Z direction. The outlet 27 is connected to the storage bin 26. The carrier 22 is movably arranged on the side of the housing 21 with the outlet 27. A receiving groove 221 is opened on the side of the carrier 22 facing the housing 21. The receiving groove 221 passes through the carrier 22 along the X direction. The carrier 22 can move relative to the housing 21 along the Y direction until the receiving groove 221 is opposite to the outlet 27.

[0026] It should be understood that in some other embodiments, the second bar can be manually clamped at the welding position. In this embodiment, there are two feeding mechanisms 20, which are arranged along the X direction, with one feeding mechanism 20 located to the left of the other. The storage bin 26 of the box 21 in the right feeding mechanism 20 is used to store the first bar, and the storage bin 26 of the box 21 in the left feeding mechanism 20 is used to store the second bar. The axis of the first bar in the storage bin 26 of the right box 21 is parallel to the X direction, and the axis of the second bar in the storage bin 26 of the left box 21 is parallel to the X direction. There are two pushing mechanisms 10 corresponding to the feeding mechanisms 20, which are arranged along the X direction, with one pushing mechanism 10 located to the left of the other pushing mechanism 10.

[0027] It should be noted that in the left feeding mechanism 20, when the receiving groove 221 is opposite to the outlet 27, the second bar in the storage bin 26 can fall into the receiving groove 221, and expose the opposite end faces of the second bar to the opposite sides of the carrier 22 along the X direction. Subsequently, the carrier 22 can move from the position opposite to the outlet 27 to the discharge position along the Y direction. When the carrier 22 is in the discharge position, the pusher 12 of the left pushing mechanism 10 is arranged with the receiving groove 221 along the X direction, and the pusher 12 is opposite to the end face of the second bar in the receiving groove 221. The pusher drive 11 of the left pushing mechanism 10 can drive the pusher 12 to extend into the receiving groove 221 along the X direction and push the second bar to move along the X direction to the welding position.

[0028] It should be noted that in the right-side feeding mechanism 20, when the receiving groove 221 is opposite to the outlet 27, the first bar in the storage bin 26 can fall into the receiving groove 221, and expose the opposite two ends of the first bar to the opposite sides of the carrier 22 along the X direction. Subsequently, the carrier 22 can move from the position opposite to the outlet 27 to the discharge position along the Y direction. When the carrier 22 is in the discharge position, the pusher 12 of the right-side pushing mechanism 10 is arranged with the receiving groove 221 along the X direction, and the pusher 12 is opposite to the end face of the first bar in the receiving groove 221. The pusher drive 11 of the right-side pushing mechanism 10 can drive the pusher 12 to extend into the receiving groove 221 along the X direction and push the first bar to move along the X direction to the welding position so that the end face of the first bar abuts against the end face of the second bar at the welding position.

[0029] Understandably, the welding mechanism 30 can abut against the first and second bars at the welding position and connect one of the first and second bars to the positive terminal of the power supply, and the other to the positive terminal of the power supply, so that current flows through the first and second bars, thereby welding the first and second bars to form a product.

[0030] The welding line 100 of the present invention has a carrier 22 that can sequentially transfer multiple first bars in the housing 21 to the discharge position. The pusher drive 11 can drive the pusher 12 to push the first bars at the discharge position to abut against the second bars located at the welding position, so that the welding mechanism 30 can weld the first bars and the second bars to form a product, thereby realizing automatic feeding of the first bars and improving welding efficiency.

[0031] Please see Figures 1 to 2 , Figure 9 , Figure 9 yes Figure 1 A schematic diagram of the structure of the first welding head 31 and the first welding seat 41. In one embodiment of this implementation, the welding line 100 further includes a clamping mechanism 40, which includes a first welding seat 41. The first welding seat 41 has a clamping groove 411 that passes through it. When the carrier 22 moves the first bar to the discharge position, the pusher 12 can push the first bar into the clamping groove 411 and make one end of the first bar extend from the side of the first welding seat 41 away from the carrier 22, so that the first bar abuts against the second bar.

[0032] Specifically, in the feeding mechanism 20, when the carrier 22 moves to the feeding position, the carrier 22 is located on one side of the first welding seat 41 along the X direction, and the receiving groove 221 is connected to the clamping groove 411, so that the pushing member 12 of the pushing mechanism 10 can push the first bar in the receiving groove 221 into the clamping groove 411, and make the first bar slide in the clamping groove 411 along the X direction until one end of the first bar extends from the end of the first welding seat 41 away from the carrier 22, so that the end face of the first bar is in contact with the end face of the second bar on the side of the first welding seat 41 away from the carrier 22.

[0033] It should be noted that the joint between the first bar and the second bar forms a weld. During the welding process of the first bar and the second bar, molten metal may be splashed out at the weld. When the molten metal splashes onto the first welding seat 41, it will cause the surface of the first welding seat 41 to be rough, which will cause the first bar to be scratched during the transfer process.

[0034] It is understandable that by opening a clamping groove 411 through the first welding seat 41, the first bar can extend from one side of the first welding seat 41, so that the weld between the first bar and the second bar can be kept away from the first welding seat 41, thereby reducing the risk of molten metal splashing from the weld and adhering to the first welding seat 41.

[0035] Please see Figures 1 to 3 , Figure 10 , Figure 3 yes Figure 1 An enlarged schematic diagram of a portion of the structure of the welding line 100; Figure 10 yes Figure 1 A schematic diagram of the structure of the second welding head 32 and the second welding seat 42 is shown. In one embodiment of this implementation, the clamping mechanism 40 further includes a second welding seat 42. The first welding seat 41 and the second welding seat 42 are arranged at intervals along a first direction. The second welding seat 42 is located on the side of the first welding seat 41 away from the support member 22. The second welding seat 42 is used to allow one end of the second bar to extend into the gap between the first welding seat 41 and the second welding seat 42, so that the first bar and the second bar abut against each other within the gap.

[0036] Specifically, the first welding seat 41 and the second welding seat 42 are arranged at intervals along the X direction. It should be noted that during the welding process, the weld between the first and second bars may expand. When the weld expands and comes into contact with other structures, it will cause relative movement between the first and second bars, resulting in the dimensions of the welded product not meeting the requirements.

[0037] Understandably, the second welding seat 42 can fix the second bar during the welding process. The first welding seat 41 and the second welding seat 42 are arranged at intervals, and the first bar and the second bar abut against each other within the interval between the first welding seat 41 and the second welding seat 42. This can ensure that the weld is located within the interval between the first welding seat 41 and the second welding seat 42, thereby reducing the risk of the weld contacting the first welding seat 41 or the second welding seat 42 when it expands.

[0038] It should be understood that in some embodiments, the second welding seat 42 is located on the side of the first welding seat 41 away from the support member 22 of the right feeding mechanism 20. The second welding seat 42 is provided with a clamping groove 421, which extends through the second welding seat 42 in the X direction. When the support member 22 of the left feeding mechanism 20 moves to the feeding position, the support member 22 is located on the side of the second welding seat 42 away from the first welding seat 41, and the receiving groove 221 is connected to the clamping groove 421. The pusher 12 of the left pushing mechanism 10 can extend into the receiving groove 221 to push the second bar in the receiving groove 221 into the clamping groove 421 and make the second bar extend into the gap between the first welding seat 41 and the second welding seat 42.

[0039] Please see Figures 1 to 2 , Figure 11 , Figure 11 yes Figure 1A schematic diagram of the structure of the feeding drive assembly 54. In one embodiment of this implementation, the welding line 100 further includes a first clamping block 51, a second clamping block 52, and a feeding drive assembly 54. Both the first clamping block 51 and the second clamping block 52 are provided with arc-shaped grooves 53. The first clamping block 51 and the second clamping block 52 are respectively connected to the feeding drive assembly 54. The feeding drive assembly 54 can drive the first clamping block 51 and the second clamping block 52 to extend into the gap and move closer to each other, so that the two arc-shaped grooves 53 form a positioning hole, and the hole wall of the positioning hole abuts against the outer peripheral wall of the first bar and the outer peripheral wall of the second bar respectively. The feeding drive assembly 54 can also drive the first clamping block 51 and the second clamping block 52 to move to the feeding position.

[0040] Specifically, the unloading drive assembly 54 includes a gripper cylinder 543, with a first gripper block 51 and a second gripper block 52 respectively mounted on the two drive ends of the gripper cylinder 543. The unloading drive assembly 54 also includes an unloading linear actuator 541, with the gripper cylinder 543 mounted on the drive end of the unloading linear actuator 541. The unloading linear actuator 541 can drive the gripper cylinder 543 to move, causing the first gripper block 51 and the second gripper block 52 to extend into the gap between the first welding seat 41 and the second welding seat 42, and causing the first gripper block 51 to extend into the gap between the first welding seat 41 and the second welding seat 42. The first clamping block 51 and the second clamping block 52 are located on opposite sides of the product along the Y direction. The gripper cylinder 543 can drive the first clamping block 51 and the second clamping block 52 to move closer to each other along the Y direction, and make the arc grooves 53 on the first clamping block 51 and the second clamping block 52 surround the weld of the product and form a positioning hole. The hole wall of the positioning hole abuts against the product and covers the weld. The unloading linear actuator 541 can drive the gripper cylinder 543 to move along the Y direction to the unloading position, so that the first clamping block 51 and the second clamping block 52 cooperate to transfer the product to the unloading position.

[0041] It is understandable that after the first and second bars are welded to form a product, the part of the product near the weld may still be molten and not cooled. The wall of the positioning hole abuts against the outer peripheral wall of the first and second bars respectively. On the one hand, this restricts the movement of the first bar relative to the second bar in the radial direction, thereby reducing the risk of product deformation caused by relative slippage of the two parts of the product on opposite sides of the weld when the product is transferred before it is fully cooled. On the other hand, when the axes of the first and second bars do not coincide, the axes of the two parts of the product on opposite sides of the weld will not coincide. As the first clamping block 51 approaches the second clamping block 52, the first clamping block 51 and the second clamping block 52 will squeeze the parts of the product on opposite sides of the weld and cause the parts of the product on opposite sides of the weld to slide relative to each other in the radial direction, so that the axes of the parts of the product on opposite sides of the weld coincide with the axis of the positioning hole, which is beneficial to improving the coaxiality of the parts of the welded product.

[0042] It should be understood that you should refer to [the relevant documentation / reference]. Figures 1 to 2 , Figure 12 , Figure 12 yes Figure 1 A schematic diagram of the structure of the tray-stacking assembly 61 is shown. The welding line 100 also includes a tray-stacking assembly 61 and a conveying assembly 62. The tray-stacking assembly 61 includes a tray-stacking gripper 612 and a tray-stacking linear actuator assembly 611. The tray-stacking linear actuator assembly 611 is composed of multiple linear actuators with mutually perpendicular driving directions. The tray-stacking gripper 612 is mounted on the end driving end of the tray-stacking linear actuator assembly 611. The conveying assembly 62 includes a conveying guide rail 621 and a conveying linear actuator 622. The conveying guide rail 621 extends along the X direction, and its top side is used to support multiple trays. The driving direction of the conveying linear actuator 622 is parallel to the X direction. The driving end of the conveying linear actuator 622 is used to abut against the trays on the conveying guide rail 621 and move the trays along the X direction so that multiple trays pass through the tray-stacking position sequentially.

[0043] It should be noted that the swivel linear actuator assembly 611 can drive the swivel jaws 612 to move to the unloading position, so that the swivel jaws 612 can clamp the product located between the first clamping block 51 and the second clamping block 52. The swivel linear actuator assembly 611 can drive the swivel jaws 612 from the unloading position to the top side of the conveying guide rail 621, and cause the swivel jaws 612 to place the product into the tray located at the swivel position on the conveying guide rail 621.

[0044] It should be understood that, in some embodiments, the conveying guide rail 621 is located on one side of the clamping mechanism 40 along the Y direction. The unloading drive assembly 54 also includes an unloading rotary driver 542. A gripper cylinder 543 is mounted on the drive end of the unloading rotary driver 542. The unloading rotary driver 542 is mounted on the drive end of the unloading linear driver 541. After the first clamping block 51 and the second clamping block 52 clamp the product, the unloading rotary driver 542 can drive the gripper cylinder 543 to rotate around an axis parallel to the Z direction, so that the product rotates until the product's axis is parallel to the Y direction. The drive direction of the unloading linear driver 541 is parallel to the Y direction. The swivel assembly 61 also includes a swivel rotary driver 613. A swivel gripper 612 is mounted on the drive end of the swivel rotary driver 613. The swivel rotary driver 613 is located on the end drive end of the swivel linear driver assembly 611. The swivel rotary driver 613 can drive the swivel gripper 612 to rotate around an axis parallel to the X direction.

[0045] Understandably, after the first clamping block 51 and the second clamping block 52 clamp the product located in the clamping mechanism 40, the product's axis is parallel to the X direction. The unloading linear driver 541 can drive the gripper cylinder 543 to move the product along the Y direction toward the conveyor guide rail 621 to the unloading position. The unloading rotary driver 542 can drive the gripper cylinder 543 to rotate around an axis parallel to the Z direction, so that when the product moves to the unloading position, the product's axis is parallel to the Y direction. After the swing plate gripper 612 clamps the product at the unloading position, the swing plate rotary driver 613 drives the swing plate gripper 612 to rotate, so that the product rotates to the point where the product's axis is parallel to the Z direction, thereby enabling the swing plate assembly 61 to arrange multiple products with axes parallel to the Z direction in the tray.

[0046] Please see Figure 1 and Figure 11 In one embodiment of this implementation, a cooling channel is provided on the first clamping block 51, which is used for coolant to flow through the first clamping block 51.

[0047] Specifically, the first clamping block 51 has two cooling ports 511, which are connected to the cooling channel. One cooling port 511 is used to allow coolant to flow into the cooling channel, and the other cooling port 511 is used to allow coolant to flow out of the cooling channel.

[0048] It is understandable that when the first clamping block 51 and the second clamping block 52 clamp the product, the heat on the product will be transferred to the first clamping block 51. The cooling channel is opened on the first clamping block 51 and the coolant flows through the first clamping block 51, which can accelerate the heat dissipation efficiency of the first clamping block 51, thereby shortening the solidification time of the molten metal at the weld of the product, and thus reducing the risk of product deformation during the product transportation process.

[0049] Please see Figures 1 to 2 , Figures 5 to 8 , Figure 6 yes Figure 5 A top view of the feeding mechanism 20; Figure 7 yes Figure 5 An enlarged schematic diagram of part of the structure of the feeding mechanism 20; Figure 8 yes Figure 5 A side view of the feeding mechanism 20. In one embodiment of this implementation, the feeding mechanism 20 further includes a movable plate 23 and a limiting component 24. The movable plate 23 is disposed on the housing 21 and surrounds the housing 21 to form a storage bin 26 for storing the first bar stock. The movable plate 23 can move relative to the housing 21 along the axial direction of the first bar stock and is fixed in relative position to the housing 21 by the limiting component 24.

[0050] Specifically, the housing 21 is used to store a first or second bar stock with its axis parallel to the X direction. The movable plate 23 is movably connected to the housing 21 in the X direction. When the movable plate 23 moves relative to the housing 21 in the X direction, the size of the storage bin 26 changes in the X direction. The limiting component 24 is installed on the movable plate 23 and can abut against the housing 21 to limit the movement of the movable plate 23 relative to the housing 21.

[0051] Understandably, the movable plate 23 is movable so that the dimension of the storage bin 26 in the X direction matches the axial dimension of the first or second bar stock, so that the movable plate 23 abuts against the end face of the first or second bar stock. This restricts the rotation of the first bar stock around an axis perpendicular to its axis, or restricts the rotation of the second bar stock around an axis perpendicular to its axis. This helps reduce the risk of the first or second bar stock getting stuck in the storage bin 26 and improves the adaptability of the feeding mechanism 20 to first and second bars stock of different lengths.

[0052] Please see Figures 1 to 2 , Figures 9 to 10 In one embodiment of this implementation, the first solder pad 41 and the second solder pad 42 are movably connected along a second direction, which is perpendicular to the first direction. The first solder pad 41 and the second solder pad 42 are movably connected relative to each other along a third direction. The second solder pad 42 and the first solder pad 41 are rotatably connected about an axis parallel to the third direction, which is perpendicular to the first and second directions.

[0053] Specifically, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The clamping mechanism 40 also includes an adjusting guide rail 43 and an adjusting slider 44. The adjusting guide rail 43 extends along the Y direction, and the adjusting slider 44 can slide along the Y direction to cooperate with the adjusting guide rail 43. The adjusting guide rail 43 is mounted on the base 63. The first welding seat 41 can be movably disposed on the adjusting slider 44 along the Z direction, and the second welding seat 42 can be rotatably disposed on the base 63 about an axis parallel to the Z direction.

[0054] It is understandable that the first welding seat 41 and the second welding seat 42 clamp the first and second bars by abutting against the outer circumferential surfaces of the first and second bars, respectively. When the radius dimensions of the first and second bars are different, after the first welding seat 41 and the second welding seat 42 clamp the first and second bars, there may be a gap between the axis of the first bar and the axis of the second bar in both the Z and Y directions, resulting in the axis of the first bar and the axis of the second bar not coinciding. The first welding seat 41 can move relative to the second welding seat 42 in the Y and Z directions to eliminate the gap between the first and second bars in the direction perpendicular to the X direction and make the axes of the first and second bars coincide. This is beneficial to improving the flexibility of adjusting the relative position of the first and second bars, thereby improving the coaxiality of the welded product. The axes of the first and second bars may intersect. The second welding seat 42 is rotatably mounted on the base 63 about an axis parallel to the Z direction. By rotating the second welding seat 42, the axes of the first and second bars can be adjusted to be parallel to each other, which helps to reduce the risk that the dimensions of the welded product do not meet expectations.

[0055] It should be understood that you should refer to [the relevant documentation / reference]. Figures 5 to 8 In some embodiments, the support member 22 is provided with a first block 28 and a second block 29 detachably disposed thereon. A portion of the support member 22 protrudes along the Z direction to form a boss 222. The boss 222 and the second block 29 are spaced apart along the Y direction. The space between the second block 29 and the boss 222 forms a receiving groove 221. The first block 28 is located in the receiving groove 221. The first block 28 is located between the second block 29 and the boss 222, and the first block 28 and the second block 29 are spaced apart. The first block 28 fills part of the space in the receiving groove 221 so that the space between the first block 28 and the second block 29 forms the remaining part of the receiving groove 221.

[0056] It is understandable that the empty portion of the receiving groove 221 can accommodate the first bar stock. When the first block 28 and the second block 29 of different sizes are replaced, on the one hand, the size of the empty portion of the receiving groove 221 in the Y direction changes, which can accommodate the first bar stock with different radius sizes. After the first bar stock enters the empty portion of the receiving groove 221, the first block 28 and the second block 29 can work together to provide a limit on the first bar stock from the opposite sides along the Y direction. This is beneficial to improving the stability of the first bar stock during the process of the carrier 22 transferring the first bar stock to the feeding position. On the other hand, it can change the relative position of the axis of the first bar stock and the carrier 22 in the Y direction when the first bar stock enters the receiving groove 221, so that when the carrier 22 moves to the feeding position, the offset of the axis of the first bar stock in the Y direction changes, thereby accommodating the first welding seat 41 moving to different positions in the Y direction.

[0057] Please see Figures 1 to 2 , Figures 9 to 10 In one embodiment of this implementation, the welding mechanism 30 includes a first welding head 31 and a second welding head 32. The first welding head 31 is used to energize a first bar stock, and the second welding head 32 is used to energize a second bar stock. The first welding head 31 is connected to a first welding seat 41 so that it can move with the first welding seat 41.

[0058] Specifically, the first welding head 31 is located on one side of the first welding base 41 along the Y direction, and the second welding head 32 is located on one side of the second welding base 42 along the Y direction. In some embodiments, the first welding head 31 is connected to the adjusting slider 44, and the second welding head 32 is mounted on the base 63 so that the first welding head 31 can slide with the first welding base 41. It is understood that when the radial dimension difference between the first bar and the second bar is large, the first welding base 41 needs to move a large distance to make the axes of the first bar and the second bar coincide, which may cause the first welding head 31 to fail to contact the first bar on the first welding base 41. The fact that the first welding head 31 can slide with the first welding base 41 can reduce the risk that the first welding head 31 cannot contact the first bar and is conducive to the normal progress of the welding process.

[0059] Please see Figures 1 to 2 , Figures 5 to 8 In one embodiment of this implementation, the housing 21 is provided with an outlet 27, and the support member 22 is provided with a protrusion. When the support member 22 moves relative to the housing 21, the protrusion can push the first bar through the outlet 27, so as to change the relative position between multiple first bars in the storage bin 26.

[0060] Specifically, the housing 21 is used to stack multiple first bars in the storage bin 26. The outlet 27 is connected to the storage bin 26 and is located on one side of the housing 21 along the Z direction. The protrusion is located on the side of the support member 22 facing the housing 21. The protrusion protrudes relative to the support member 22 along the Z direction and can extend into the storage bin 26 through the outlet 27.

[0061] Understandably, when multiple first bars are stacked in the storage bin 26, their outer peripheral surfaces abut against each other and work together to form a stable structure. This may restrict the relative movement between the multiple first bars, causing them to become blocked in the storage bin 26, thus hindering the discharge of material from the feeding mechanism 20. When the carrier 22 moves, the protrusion pushes the first bars in the storage bin 26 through the outlet 27, causing them to shake and disrupt the stable structure formed by the multiple first bars. This also causes relative movement between the multiple first bars along the radial direction, thereby changing the arrangement of the multiple first bars in the storage bin 26 and reducing the risk of them becoming blocked.

[0062] It should be understood that in some of these implementations, the bottom wall of the housing 21 is a slope 211, which is connected to the side wall of the outlet 27 so that the first bar can slide along the slope 211 to the outlet 27. This arrangement helps to reduce the risk of material blockage in the feeding mechanism 20.

[0063] Please see Figures 1 to 2 , Figures 5 to 8 In one embodiment of this implementation, the feeding mechanism 20 includes a push ball 25, and the carrier 22 has an installation groove. The push ball 25 is rotatably engaged with the installation groove and is partially exposed outside the installation groove to form a protrusion.

[0064] Specifically, the mounting groove is located on the side of the support member 22 facing the housing 21. It is understood that after the protrusion extends into the storage bin 26 through the outlet 27, it can abut against the outer circumferential surface of the first bar stock. When the support member 22 drives the protrusion to move, friction may occur between the protrusion and the outer circumferential surface of the first bar stock. By forming the protrusion through the pushing ball 25 and rotatably mounting the pushing ball 25 on the support member 22, on the one hand, the contact area between the protrusion and the first bar stock can be reduced; on the other hand, the protrusion can rotate under the action of the frictional force between the protrusion and the first bar stock, thereby reducing the frictional force between the protrusion and the first bar stock and thus reducing the risk of damage to the outer circumferential surface of the first bar stock.

[0065] It should be understood that you should refer to [the relevant documentation / reference]. Figures 1 to 3 In some embodiments, a pressure sensor is provided on the pusher 12 of the right pusher mechanism 10, and the pressure sensor is electrically connected to the pusher drive 11. The clamping mechanism 40 also includes a positioning sensor 64, which is positioned opposite the gap between the first welding seat 41 and the second welding seat 42. The positioning sensor 64 can detect whether the first or second bar material is inserted into the gap between the first welding seat 41 and the second welding seat 42. The positioning sensor 64 is electrically connected to the pusher drive 11 of the left pusher mechanism 10.

[0066] Understandably, during the process of conveying the first and second bars to the welding position, the pusher 12 of the left pusher mechanism 10 first pushes the second bar to move. When the second bar moves to a preset position in the gap between the first welding seat 41 and the second welding seat 42, the position sensor 64 is activated and can send a control signal to the pusher driver to stop the pusher driver 11 from driving the pusher 12, so that the second bar is fixed in the current position. Subsequently, the pusher 12 of the left pusher mechanism 10 pushes the first bar to move. When the first bar moves to abut against the second bar, the force on the pusher 12 changes abruptly and rises. The pressure sensor can capture the rising edge of the left pusher mechanism 10 and send a control signal to the pusher driver 11 to stop the pusher driver 11 from driving the pusher 12, or to apply a preset driving force to the pusher 12 so that the clamping force between the first and second bars meets the expectation. This configuration, on the one hand, ensures that the weld between the first and second bars is located at a predetermined position within the gap between the first welding seat 41 and the second welding seat 42, reducing the risk of the weld coming into contact with the first welding seat 41 or the second welding seat 42, and also reducing the risk of molten metal splashing onto the first welding seat 41 and the second welding seat 42. On the other hand, it ensures that the contact force between the first and second bars meets expectations, thereby improving the welding quality.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
