Description

TECHNICAL FIELD

[0001] The present application relates to the field of copper bar processing equipment, in particular to a copper bar flat end face and end face marking device. BACKGROUND

[0002] In the production and manufacturing process of copper bars, after forming through rolling, drawing and other processes, it is necessary to cut them into short copper bars according to specific sizes according to actual application requirements. However, the two end faces of the cut short copper bars will inevitably produce more obvious burrs and flash due to the influence of the cutting process, and the flatness of the end face is extremely poor, and even local concave or convex may occur. These defects make the short copper bars unable to directly meet the requirements of subsequent assembly, connection or precision machining. Among them, burrs and flash not only may scratch the packaging or other workpieces during storage and transportation, but also may affect the assembly accuracy and connection strength in subsequent machining, welding and other links, and even cause safety hazards; and the unevenness of the end face will directly affect the fit of the short copper bar with other parts, reducing the quality stability of the overall product.

[0003] At the same time, with the continuous expansion of the application field of copper bars, such as in the power, communication, precision machinery and other industries, higher requirements are put forward for the traceability and identification clarity of short copper bars. End face marking as a key means to identify the specifications, materials, production batches and other information of short copper bars, the marking quality is directly related to the reading accuracy and durability of the information. However, due to the unevenness of the original end face of the short copper bar after cutting, problems such as light spot dispersion, uneven marking depth, and edge blur may occur during laser marking, resulting in poor marking effect and difficulty in meeting the identification needs in industrial production. Especially for short copper bars used in some small precision equipment, unclear identification may directly affect the subsequent maintenance and replacement work.

[0004] In order to solve the above problems, the existing technology usually adopts a step-by-step processing mode: first, the end faces of the short copper bars are processed by milling equipment to remove burrs and ensure flatness, and then the processed short copper bars are transported to the laser marking equipment for marking. However, this step-by-step processing mode has obvious defects: on the one hand, the transportation process between the two processes increases the working hours and labor costs, and for batch production of short copper bars, the problem of low efficiency is more prominent; on the other hand, the size of the short copper bar is relatively small, and it is more likely to be displaced or damaged during transportation, resulting in a decrease in positioning accuracy of the short copper bar after flat end face processing during marking, further affecting the marking quality.

DETAILED DESCRIPTION

[0027] The present application provides a copper rod flat end face and end face marking device. In order to make the purpose, technical scheme and effect of the present application more clear and explicit, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the protection scope of the present application.

[0028] Please refer to Figures 1 to 3This invention provides a copper rod flat end face and end face marking device, including a worktable 11, an inclined top frame 12 disposed on the worktable 11, a feeding box 21 disposed behind the worktable 11, a guide sloping plate 22 disposed on the front end face of the feeding box 21, a first milling machine 31 and a second milling machine 32 disposed on the worktable 11 and respectively located on both sides below the guide sloping plate 22. The guide sloping plate 22 extends above the worktable 11 and its supporting surface has a first discharge port 23 at its lowest position. The worktable 11 is provided with a lower material support structure 4 located between the first milling machine 31 and the second milling machine 32. The inclined top frame 12 is provided with a material support structure 4 that cooperates with the lower material support structure 4. The upper clamping structure 5 for conveying a single copper rod 28 downwards; the guide sloping plate 22 is provided with a first aligning structure 6 for aligning the copper rod 28 located at the lowest point of the guide sloping plate 22; the workbench 11 is provided with a second discharge port 111 located below the first discharge port 23; the bottom of the workbench 11 is provided with an openable receiving assembly 7 for receiving the copper rod 28 falling from the second discharge port 111; the receiving assembly 7 is provided with a second aligning structure 8 for aligning the copper rod 28; the bottom of the workbench 11 is provided with a first marking structure 91 and a second marking structure 92 for marking the two ends of the steel rod respectively; and a feeding basket 10 is provided below the receiving assembly 7.

[0029] The short copper rods 28 to be processed are pre-placed in the feeding box 21 and are conveyed in an orderly manner by the guide sloping plate 22 at the front end of the feeding box 21. The short copper rods 28 slide down along the supporting surface of the guide sloping plate 22. The lower support structure 4 restricts the copper rods 28 at the lowest point of the guide sloping plate 22 from falling to the first discharge port 23. Then, the first aligning structure 6 aligns the copper rods 28 located at the lowest point of the guide sloping plate 22, so that the end of the copper rod 28 away from the first aligning structure 6 is aligned with the inner side of the guide sloping plate 22.

[0030] The first milling machine 31 and the second milling machine 32 operate continuously at high speed. Then, the upper clamping structure 5 descends and, together with the lower supporting structure 4, reliably clamps the copper rod 28 and works together to move the copper rod 28 out of the first discharge port 23. Then, the copper rod 28 is moved downward into the processing position between the first milling machine 31 and the second milling machine 32. The milling heads of the first milling machine 31 and the second milling machine 32 respectively perform milling treatment on both ends of the copper rod 28 to remove burrs and flash and ensure the flatness of the end face.

[0031] After processing, the copper rod 28 is moved away from the processing position under the continued conveying action of the upper clamping structure 5 and the lower supporting structure 4. The upper clamping structure 5 releases the copper rod 28, and the copper rod 28 falls into the receiving component 7 below through the second discharge port 111 of the worktable 11 under the action of gravity. The receiving component 7 closes to receive the copper rod 28, and the second aligning structure 8 aligns the copper rod 28 again to ensure the positioning accuracy during marking.

[0032] The first marking structure 91 and the second marking structure 92 on the bottom of the workbench 11 laser mark the two ends of the copper rod 28 to mark the specifications, material and other information.

[0033] After marking is completed, the receiving component 7 opens, and the copper rod 28 falls into the material feeding basket 10 below, completing the entire processing flow.

[0034] The copper rod 28 with a flat end face and an end face marking device provided by the present invention have the following advantages:

[0035] 1. The lower support structure 4 first restricts the fall of the copper rod 28 at the lowest point of the guide sloping plate 22. Combined with the first aligning structure 6, it precisely aligns the end of the copper rod 28 furthest from the aligning structure with the inner surface of the guide sloping plate 22, achieving initial precise positioning during the loading stage. The upper clamping structure 5 and the lower support structure 4 jointly clamp and transport the copper rod 28, ensuring its stable posture when entering the milling position and avoiding insufficient end-face flatness due to positional deviation during milling. After the copper rod 28 falls into the receiving assembly 7, the second aligning structure 8 aligns it again, providing reliable positioning for marking. This multi-positioning design ensures higher end-face flatness after milling, stable laser spot focusing during marking, effectively avoiding problems such as inconsistent marking depth and blurred edges, and significantly improving the consistency of product processing quality.

[0036] 2. The device employs a coordinated transfer method using an upper clamping structure 5 and a lower supporting structure 4 to achieve seamless transfer of the copper rod 28 from the guide slant plate 22 to the milling position and then to the receiving assembly 7. This eliminates the need for manual transfer or secondary positioning between processing steps in traditional step-by-step processing. Simultaneously, the first milling machine 31 and the second milling machine 32 operate continuously at high speed, avoiding downtime caused by waiting for the copper rod 28 to be positioned. The overall process is tightly integrated, reducing unnecessary time losses, making it particularly suitable for batch processing of short copper rods 28 and significantly improving production efficiency.

[0037] Specifically, the lower support structure 4 includes a cylinder bracket 41 fixed on the worktable 11, a thin guide rod cylinder 42 (specifically a three-guide rod thin cylinder) mounted on the cylinder bracket 41 and facing the first discharge port 23, and a support bar 43 mounted on the end of the guide rod of the thin guide rod cylinder 42. Using the thin guide rod cylinder 42 as the driving component, it features small size, smooth operation, and high precision. When it is necessary to restrict the descent of the copper rod 28, the thin guide rod cylinder 42 can quickly drive the support bar 43 to extend towards the first discharge port 23, precisely blocking the copper rod 28; and when the copper rod 28 is subsequently moved, it can quickly retract, ensuring the smooth removal of the copper rod 28. This rapid and precise action response effectively matches the automated process rhythm of the entire device, reduces waiting time between processes, and improves overall processing efficiency.

[0038] The shape and position of the support bar 43 are designed to work well with the upper clamping structure 5. When clamping the copper rod 28, the support bar 43 provides stable support from below, forming a reliable clamping effect together with the upper clamping structure 5, preventing the copper rod 28 from loosening, falling, or rotating during the transfer process. Especially for short copper rods 28, this stable clamping cooperation ensures that their posture remains stable throughout the entire process of moving out of the first discharge port 23, entering the processing position, and moving away from the processing position, further guaranteeing the accuracy of milling and marking.

[0039] Specifically, the upper clamping structure 5 includes a servo electric cylinder 51 mounted on the downward-facing inclined top frame 12 and a pressure bar frame 52 mounted on the output end of the servo electric cylinder 51 and facing the first discharge port 23. The bottom of the pressure bar frame 52 has a positioning arc groove 521 adapted to the shape of the bar. This contouring design allows it to fit tightly against the outer surface of the short copper bar 28, increasing the clamping contact area. Compared to planar clamping, the positioning arc groove 521 can effectively limit the radial rotation and axial sliding of the copper bar 28 during clamping. Especially during transfer and milling, it can provide more stable constraints for the copper bar 28, preventing the copper bar 28 from shaking and affecting the flatness of the milled end face, thus further ensuring the processing quality.

[0040] The servo electric cylinder 51 has high-precision displacement control and stable output force, enabling precise control of the descent, transfer, and ascent of the pressure bar frame 52. When used in conjunction with the lower support structure 4 to clamp the copper rod 28, it can ensure appropriate clamping force by precisely controlling the descent distance, thus preventing the copper rod 28 from falling off due to excessively loose clamping and preventing deformation of the copper rod 28 due to excessively tight clamping. During the transfer of the copper rod 28, it can move smoothly and strictly according to the preset trajectory, ensuring that the copper rod 28 accurately enters the milling machining position and moves away smoothly, greatly improving the controllability and accuracy of the entire transfer process.

[0041] The pressure bar frame 52 driven by the servo electric cylinder 51 and the support bar crossbar 43 of the lower support structure 4 form a corresponding clamping relationship, and their movements are closely coordinated. When it is necessary to clamp the copper rod 28, the pressure bar frame 52 descends precisely and together with the support bar crossbar 43 forms a reliable clamp; during the transfer process, the two work together to maintain a stable clamping state; after moving to the target position, the servo electric cylinder 51 precisely controls the pressure bar frame 52 to release, ensuring that the copper rod 28 falls smoothly.

[0042] Furthermore, the top of the inclined top frame 12 is provided with two linear bearings 53, and the top of the pressure bar frame 52 is provided with a guide rod 54 that is slidably connected to the linear bearings 53. The linear bearings 53 and the guide rod 54 are slidably connected to form a reliable guiding structure. When the servo cylinder 51 drives the pressure bar frame 52 to perform lifting and conveying actions, the guide rod 54 slides precisely along the linear bearings 53, which can effectively limit the swaying, shaking or rotation of the pressure bar frame 52 during the movement, ensuring that the pressure bar frame 52 always moves smoothly along the preset trajectory. This not only further improves the positioning accuracy of the pressure bar frame 52 when it cooperates with the lower material support structure 4 to clamp the copper rod 28, ensuring that the copper rod 28 can accurately enter the milling processing position, but also reduces the additional load on the servo cylinder 51 caused by the unstable movement of the pressure bar frame 52, extends the service life of the servo cylinder 51, and enhances the stability and reliability of the entire upper clamping structure 5.

[0043] In this embodiment, the first alignment structure 6 includes a mounting cylinder 61 horizontally positioned at the lowest point of the side of the guide swashplate 22, a first alignment cylinder 62 positioned at the outer end of the mounting cylinder 61, and a pusher head positioned at the output end of the first alignment cylinder 62. A through hole is provided on the side of the guide swashplate 22, allowing the mounting cylinder 61 to communicate with the interior of the guide swashplate 22. The first alignment cylinder 62 drives the pusher head through the through hole on the side of the guide swashplate 22 and into its interior, pushing the copper rod 28 so that the end furthest from the pusher head is reliably aligned with the inner side of the guide swashplate 22, effectively ensuring the uniform initial posture of the copper rod 28 before entering subsequent clamping and milling processes. This precise alignment effect provides a good foundation for the stable clamping of the upper clamping structure 5 and the lower support structure 4, avoiding problems such as unstable clamping or decreased milling accuracy caused by the offset position of the copper rod 28.

[0044] In this embodiment, the worktable 11 is equipped with a fixed base 33 for fixing the first milling machine 31. A slide block 34 capable of lateral movement is slidably disposed on the worktable 11. The second milling machine 32 is disposed on the slide block 34. The worktable 11 is equipped with a rotatable lead screw 35, on which a lead screw nut 36 is fitted. The lead screw nut 36 is fixed on the slide block 34. A handwheel 37 is disposed at the output end of the lead screw. When the handwheel 37 is rotated, the movement distance of the slide block 34 can be precisely controlled by the pitch of the lead screw 35, flexibly adjusting the distance between the first milling machine 31 and the second milling machine 32, and quickly adapting to the processing requirements of short copper rods 28 of different lengths. This ensures that the first milling machine 31 and the second milling machine 32 can always maintain the optimal milling position relationship with the two end faces of the copper rod 28. Regardless of the change in the length of the copper rod 28, the milling depth of the two end faces can be guaranteed to be uniform and the flatness consistent, effectively avoiding the problem of reduced milling quality caused by distance adjustment errors.

[0045] Preferred, see Figure 5As shown, the bottom of the feeding box 21 forms a guide plate groove 24 that matches its front end face and an inclined surface 25 that slopes towards the guide plate groove 24. A lifting feeding plate 26 is provided at the guide plate groove 24. The top of the lifting feeding plate 26 is provided with a feeding arc 27 facing the guiding inclined plate 22, which can reliably lift a single copper rod 28 and smoothly transfer it to the guiding inclined plate 22. This effectively avoids the congestion and jamming caused by multiple copper rods 28 rushing into the guiding inclined plate 22 at the same time, and ensures the orderliness of the feeding process. The lifting feeding plate 26 is driven and connected to the lifting mechanism (not shown in the figure).

[0046] This structure eliminates the need for manual placement of copper rods 28 one by one. Instead, a batch of short copper rods 28 are placed into the feeding box 21. The inclined surface 25 at the bottom of the feeding box 21 allows the short copper rods 28 to slide naturally into the guide plate groove 24 under gravity. Combined with the periodic upward movement of the lifting feeding plate 26, it can accurately achieve the effect of feeding copper rods 28 one by one onto the guide plate 22.

[0047] In this embodiment, see Figure 3 As shown, the receiving assembly 7 includes a vertical plate 71 fixed to the bottom of the workbench 11, a swing plate 72 that swings towards or away from the vertical plate 71, and a swing cylinder 73 that drives the swing plate 72 to swing. The cylinder body of the swing cylinder 73 is hinged to the workbench 11, and the piston rod end of the swing cylinder 73 is hinged to the back of the swing plate 72. When the vertical plate 71 and the swing plate 72 are joined, they form a receiving corner groove 74. When the swing plate 72 moves closer to and joins the vertical plate 71 under the drive of the swing cylinder 73, the receiving corner groove 74 can reliably receive the copper rod 28 falling from the second discharge port 111. After the copper rod 28 falls into the receiving corner groove 74, its outer circumference is in contact with the inner side of the vertical plate 71 and the swing plate 72, which can effectively limit the horizontal displacement of the copper rod 28, provide a stable foundation for the subsequent alignment operation of the second alignment structure 8, ensure that the copper rod 28 is in the preset precise position during marking, and improve the marking accuracy.

[0048] After marking is completed, the swing cylinder 73 drives the swing plate 72 to quickly swing away from the vertical plate 71, the receiving corner groove 74 opens, and the copper rod 28 falls smoothly into the feeding basket 10 under the action of gravity.

[0049] For details, see Figure 1 and Figure 4As shown, the second alignment structure 8 includes a positioning step 81 on the end face of the swing plate 72 facing the vertical plate 71, a support plate 82 on the back of the swing plate 72, a driving wheel 83 and a driven wheel 84 rotatably mounted on the support plate 82, and a conveyor belt 85 that is wound around the driving wheel 83 and the driven wheel 84 to form a transmission connection. The conveyor belt 85 is provided with a pusher 86 for pushing the copper rod 28 to align with the positioning step 81. The support plate 82 is provided with a motor 87 for driving the driving wheel 83 to rotate. The swing plate 72 is provided with a clearance groove 721 for the pusher 86 to extend into the receiving corner groove 74.

[0050] When the copper rods 28 that have fallen into the receiving corner groove 74 need to be precisely aligned, the motor 87 drives the drive wheel 83 to rotate, which in turn moves the conveyor belt 85 and the pusher flag 86. The pusher flag 86 passes through the clearance groove 721 on the swing plate 72 and extends into the receiving corner groove 74, pushing the copper rods 28 closer to the positioning step 81 and ensuring that they reliably abut against it, thus ensuring that the copper rods 28 are in a uniform position within the receiving corner groove 74. This precise alignment provides a stable positioning basis for the marking operations of the first marking structure 91 and the second marking structure 92, avoiding problems such as misalignment and blurring of marking information caused by the offset position of the copper rods 28, and significantly improving the marking quality. It should be emphasized that after the pusher flag 86 completes the alignment action, it will be pushed out of the receiving corner groove 74 and will not affect the marking operation of the second marking structure 92.

[0051] Specifically, the pusher flag 86 includes a support 861 fixed on the conveyor belt 85, a pin 862 mounted on the support 861, a flag body 863 rotatable around the pin 862, and a torsion spring wound around the pin 862. The torsion spring pulls the flag body 863, causing it to abut against the support 861 and maintain an upright pushing posture, remaining in its initial position with the conveyor belt 85. When the conveyor belt 85 moves the pusher flag 86 towards the copper rod 28, the flag body 863 first contacts the end of the copper rod 28. At this time, the copper rod 28 is not restricted by the positioning step 81, and the flag body 863, relying on the upright state maintained by the torsion spring, pushes the copper rod 28 towards the positioning step 81.

[0052] When the copper rod 28 is pushed to contact the positioning step 81, the positioning step 81 rigidly limits the copper rod 28, preventing it from moving further. At this point, the flag body 863 experiences a reverse resistance from the copper rod 28. When the resistance overcomes the torsion spring force, the flag body 863 rotates around the pin 862 to flip over, avoiding the end of the copper rod 28 and preventing excessive compression of the copper rod 28.

[0053] After the pusher flag 86 continues to move to the limit position with the conveyor belt 85, it returns. At this time, the flag body 863 is freed from the constraint of the copper rod 28 and rotates in the opposite direction around the pin 862 under the action of the torsion spring. It then rests against the support 861 and returns to the initial pushing posture, preparing for the next pushing action.

[0054] The design of the pusher flag 86 has the following advantages: 1. Avoiding interference with the marking process and ensuring smooth marking: When the copper rod 28 is pushed to contact the positioning step 81, the flag body 863 flips around the pin 862 and exits the receiving corner groove 74 under the action of the moving resistance, completely avoiding the end area of ​​the copper rod 28. This avoidance design ensures that the second marking structure 92 will not have spatial interference with the pusher flag 86 when marking the end face of the copper rod 28, providing sufficient working space for the marking head, ensuring that the laser beam can be accurately focused on the end face of the copper rod 28, and avoiding marking failure or information incompleteness caused by structural obstruction. 2. The conveyor belt 85 operates unidirectionally and periodically, simplifying the control logic. After the flag body 863 flips to avoid the copper rod 28, it can continue to move along the original direction to the end of the stroke with the conveyor belt 85, and then return to reset with the conveyor belt 85. One push-alignment cycle can be completed without reversing the start of the conveyor belt 85 midway.

[0055] 3. After the copper rod 28 is stopped by the positioning step 81, the flag body 863 achieves flexible flipping through the balance between the torsion spring force and the moving resistance, rather than rigidly colliding with the copper rod 28 or the positioning step 81. This design avoids wear or deformation of the push flag 86, copper rod 28, and positioning step 81 caused by hard impact, significantly reducing the risk of component damage, extending the service life of the push flag 86 and related structures, and reducing equipment maintenance costs.

[0056] In this embodiment, the first marking structure 91 includes a first manually adjustable lifting slide 911 fixed to the bottom surface of the workbench 11 and a first laser marking device 912 disposed on the slide of the first manually adjustable lifting slide 911. The second marking structure 92 includes a second manually adjustable lifting slide 921 fixed to the bottom surface of the workbench 11 and a second laser marking device 922 disposed on the slide of the second manually adjustable lifting slide 921. The first laser marking device 912 and the second laser marking device are symmetrically arranged. The first laser marking device 912 is used to mark one end face of the copper rod 28, and the second laser marking device 922 is used to mark the other end face of the copper rod 28.

[0057] The manually adjustable lifting slide can precisely adjust the height of the first laser marking device 912 and the second laser marking device 922, thereby accurately controlling the vertical distance between the marking device and the end face of the copper rod 28. Since the end face heights of copper rods 28 of different diameters within the receiving groove 74 vary, manually adjusting the slide ensures the laser marking device is always at the optimal focal length, guaranteeing laser beam focusing accuracy and avoiding problems such as blurred or distorted markings caused by focal length deviations. This ensures clear marking of copper rods 28 of different specifications.
