Description

Technical Field

[0001] This utility model relates to the field of copper tube manufacturing technology, and in particular to a copper tube detection and marking device. Background Technology

[0002] After the raw material electrolytic copper undergoes smelting, rolling, and coiling processes to reach a semi-finished product state, a winding machine is needed to wind a 2-ton heavy coil into smaller coils weighing approximately 100 kilograms for easier packaging and transportation. During the winding process, the product must be inspected for defects. If a defect is detected by the system, an inkjet printer can be used to apply ink to the defective area. The inkjet print marks on the copper tube surface must be dried promptly to prevent omissions or transfer to other tube walls, which could lead to product defects, scrapping, and abnormal product testing.

[0003] However, in the existing copper tube inspection and marking process, the inkjet device itself may deviate from its initial position. After inkjet printing, the copper tube needs to be dried for a certain length. Within the drying length, the correction and guidance device cannot be used to guide the copper tube. As a result, the copper tube may also deviate during the inkjet section due to changes in conveyor tension and differences in its own physical characteristics, leading to deviation from the initially set inkjet position. Furthermore, the instability of the conveyor speed may also cause errors in the inkjet position. All of these factors result in abnormalities in product inspection and marking, affecting product inspection and shipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a copper pipe detection and marking device to solve one or more of the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides a copper tube detection and marking device, mounted on a machine base, comprising:

[0006] The conveyor table and the inkjet chamber located on the adjacent side of the conveyor table are provided. The conveyor table is provided with a conveying structure for transversely conveying the copper tube into the inkjet chamber. A limiting structure is fixedly provided in the inkjet chamber. An inkjet gun is fixedly provided on the adjacent side of the limiting mechanism. The inkjet gun performs point inkjet on the copper tube.

[0007] The limiting mechanism includes a limiting cover, which has an open design on the side away from the inkjet gun and a closed design on the side close to the inkjet gun. It is fixedly connected to the inkjet gun through a first connecting rod. Limiting wheels are provided on the upper and lower sides inside the limiting cover. The limiting wheels are rotatably connected inside the limiting cover and roll against the upper and lower sides of the copper tube. A speed sensor for detecting the rotational speed of the limiting wheels is provided inside the limiting cover.

[0008] The conveyor is equipped with a detection unit. When a defect is detected on the copper tube by the detection unit, the speed sensor is triggered to start detecting the rotation speed of the limit wheel. After controlling the predetermined time, the inkjet gun is triggered to spray ink.

The top end of the bidirectional lead screw is connected to a handle. By twisting the handle, the bidirectional lead screw is driven to rotate, so that the upper and lower sliders slide vertically closer or further apart.

[0011] Preferably, the fixed wheel frame includes a cross frame fixed to one side of the upper slider. The bottom end of the cross frame has multiple screw holes along its length. A movable frame is connected to the bottom end of the cross frame along the screw hole positions. The bottom end of the movable frame has multiple shaft holes along its length, and a fixed wheel is rotatably connected to at least one shaft hole.

[0012] Preferably, a guide wheel frame is provided on the side of the inkjet chamber facing the conveying mechanism, and a second guide cylinder is provided on the guide wheel frame. The first guide cylinder and the second guide cylinder are at the same height, and the copper tube is conveyed into the inkjet chamber in sequence along the first guide cylinder and the second guide cylinder.

[0013] Preferably, a second connecting rod is fixedly connected to the side of the guide wheel frame away from the conveying mechanism. The second connecting rod is laterally inserted into the inkjet chamber and fixedly connected to the limiting cover.

[0014] Preferably, the conveyor is divided into two parallel layers, and the two layers are fixedly connected by an inclined plate, with the bottom of the column inserted and fixed between the two layers of conveyor.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a copper tube detection and marking device is mounted on a machine base, including a conveyor table 1 and an inkjet chamber 2 located adjacent to the conveyor table 1. The conveyor table 1 is provided with a conveying structure for laterally conveying the copper tube 100 into the inkjet chamber 2. A limiting structure is fixedly provided inside the inkjet chamber 2, and an inkjet gun 3 is fixedly provided on the adjacent side of the limiting structure. The inkjet gun 3 performs dot-matrix inkjet printing onto the copper tube 100. The limiting structure includes a limiting cover 4, with an opening on the side of the limiting cover 4 away from the inkjet gun 3. The limiting cover 4 is close to the inkjet gun 3. One side is enclosed and fixedly connected to the inkjet gun 3 via a first connecting rod 5. Limiting wheels 6 are provided on the upper and lower sides of the limiting cover 4. The limiting wheels 6 are rotatably connected to the limiting cover 4 and roll against the upper and lower sides of the copper tube 100. A speed sensor for detecting the rotation speed of the limiting wheels 6 is provided inside the limiting cover 4. A detection unit is provided on the conveyor table 1. When a defect is detected on the copper tube 100 by the detection unit, the speed sensor is triggered to start detecting the rotation speed of the limiting wheels 6. After controlling a predetermined time, the inkjet gun 3 is triggered to spray ink.

[0025] This utility model is based on the existing copper tube detection and marking process. It is mounted on a machine (not shown in the figure), which is a long platform. The machine has a conveyor 1 and an inkjet chamber 2 located adjacent to the conveyor 1. The conveyor 1 has a conveying structure for laterally conveying the copper tube 100 into the inkjet chamber 2. A limiting structure is fixed inside the inkjet chamber 2. An inkjet gun 3 is fixed to the adjacent side of the limiting mechanism. The inkjet gun 3 is a conventional automatic inkjet gun, such as a pneumatic automatic inkjet gun. The automatic inkjet gun has its own ink cartridge and an external air inlet pipe with a vent valve. The limiting mechanism includes a limiting cover 4. The side of the limiting cover 4 closest to the inkjet gun 3 is closed and fixedly connected to the inkjet gun 3 via a first connecting rod 5. The side of the limiting cover 4 furthest from the inkjet gun 3 is open. The design includes a limiting cover 4 with limiting wheels 6 on the upper and lower sides facing each other. The limiting wheels 6 are rotatably connected inside the limiting cover 4 and roll against the upper and lower sides of the copper tube 100. The limiting cover 4 is equipped with a speed sensor for detecting the rotation speed of the limiting wheels 6. The conveyor table 1 is equipped with a detection unit. The speed sensor can be a conventional sensor such as photoelectric or laser, for example, a magnetoelectric tachometer, a photoelectric tachometer, or a laser tachometer. The detection unit (the specific selection varies and is not shown in the figure) can be a conventional instrument such as an eddy current flaw detector. It is used for online and offline flaw detection of various non-ferrous and ferrous metal tubes, bars, wires, filaments, and profiles. It has high detection sensitivity for defects in metal tubes, bars, wires, filaments, and profiles, such as surface cracks, dark seams, slag inclusions, and open cracks.

[0026] Therefore, when the detection unit detects a defect on the copper tube 100 in real time, it triggers the speed sensor to start detecting the rotational speed of the limit wheel 6. Since the relative position of the detection unit with respect to the conveying structure, the conveyor table 1, and the machine tool remains unchanged, and the relative position of the limit wheel 6 with respect to the limit cover 4, the inkjet gun 3, the inkjet chamber 2, and the machine tool also remains unchanged, the limit wheel 6 is used to guide and correct the copper tube 100, ensuring that the inkjet gun 3 is always stably aligned with the copper tube 100. Furthermore, since the limit cover 4 faces away from the inkjet gun 3, it prevents ink from the inkjet gun 3 from contaminating the limit wheel 6, thus preventing the limit wheel 6 from contaminating the copper tube 100 normally. On the other hand, when a defect is detected, the speed sensor is immediately triggered to start detecting the rotational speed of the limit wheel 6. Moreover, the lateral distance between the detection unit, the limit wheel 6, and the inkjet gun 3 is fixed. Thus, by calculating the rotational speed of the limit wheel 6 based on the fixed distance, a predetermined time can be calculated, and the inkjet gun 3 is triggered to perform point inkjet on the copper tube 100. For example, the normally closed vent valve is triggered to open instantaneously, so that compressed air in the air inlet pipe enters the inkjet gun 3, so that the inkjet gun 3 performs point inkjet, avoiding the error in inkjet position caused by the deviation of the transmission speed, and realizing a more stable and accurate detection and marking process.

[0027] The system can be designed using a system similar to existing conventional conveyor belt inkjet printing systems. The core component is a controller (such as a PLC, microcontroller, or industrial PC). The controller has a built-in timer, which is a software function block within the controller. The vent valve is a conventional high-speed response solenoid valve. The speed sensor detects the rotation speed of the limit wheel 6 and transmits the speed signal (V) to the controller. The timer calculates the time (T1) required for it to reach the next specific action position. After adding a delay time (T2), an instantaneous action (opening the vent valve) is triggered, thus realizing the entire marking process.

[0028] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the conveying structure includes a column 7 erected on a conveyor platform 1. Three sliders 8 are slidably connected to the column 7. A first guide cylinder 9 is connected to one side of the middle slider 8 to guide the copper tube 100 through. The copper tube 100 passes through the first guide cylinder 9 and the middle slider 8 in sequence and is sent into the inkjet chamber 2. A fixed wheel frame is connected to one side of the upper slider 8. A fixed wheel 10 is rotatably connected to the bottom end of the fixed wheel frame. The fixed wheel 10 is designed to rotate passively. A moving wheel frame 11 is connected to one side of the lower slider 8. A moving wheel 12 is rotatably connected to the moving wheel frame 11. The moving wheel frame 11 is equipped with a driving part, such as a conventional drive motor, to drive the moving wheel 12 to rotate axially. That is, the moving wheel 12 is designed to rotate actively. The fixed wheel 10 and the moving wheel 12 are respectively abutted against the upper and lower sides of the copper tube 100 to realize the conveying of the copper tube 100.

[0029] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the columns 7 are symmetrically arranged on the front and rear sides of the conveyor table 1. The front and rear ends of the slider 8 are respectively provided with through holes and are sleeved on the columns 7 along the through holes. The middle of the slider 8 is provided with a through hole. A bidirectional lead screw 13 is erected on the conveyor table 1 between the columns 7. The bottom end of the bidirectional lead screw 13 is rotatably connected to the conveyor table 1. The bidirectional lead screw 13 passes through each through hole in sequence and is threadedly engaged with the through holes of the upper and lower sliders 8. That is, the through hole on the middle slider 8 is not engaged with the bidirectional lead screw 13, and the position of the copper tube 100 passing through the middle slider 8 avoids the position of the through hole. The top of the bidirectional lead screw 13 is connected to a handle 14. Thus, for copper tubes 100 of different diameters, by twisting the handle 14, the bidirectional lead screw 13 is driven to rotate, so that the upper and lower sliders 8 slide vertically relative to each other, so that the fixed wheel 10 and the moving wheel 12 abut against the upper and lower sides of the copper tube 100 respectively, thereby realizing the conveying of the copper tube 100.

[0030] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the fixed wheel frame includes a horizontal frame 15 fixed to one side of the upper slider 8. The bottom end of the horizontal frame 15 has multiple screw holes along its length. A movable frame 16 is connected to the bottom end of the horizontal frame 15 along the screw hole positions, so that the movable frame 16 can be adjusted to different positions along the length of the bottom end of the horizontal frame 15. The bottom end of the movable frame 16 has multiple shaft holes 17 along its length, and a fixed wheel 10 is rotatably connected to at least one shaft hole 17, so that the fixed wheel 10 can be adjusted to different positions along the length of the bottom end of the movable frame 16 and multiple fixed wheels can be arbitrarily set.

[0031] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the inkjet chamber 2 has a guide wheel frame 18 on the side facing the conveying mechanism. The guide wheel frame 18 has a second guide cylinder 19. The first guide cylinder 9 and the second guide cylinder 19 are at the same height. Thus, the copper tube 100 is conveyed into the inkjet chamber 2 in sequence along the first guide cylinder 9, the middle slider 8, and the second guide cylinder 19. A fastening bolt can also be provided on the side of the slider 8. The position of the middle slider 8 can be moved up and down until the height of the first guide cylinder 9 and the second guide cylinder 19 are the same. Then, the fastening bolt on the middle slider 8 is tightened. After adjusting the relative sliding position of the upper and lower sliders 8 by turning the knob handle 14, the fastening bolts on the upper and lower sliders 8 are tightened again to ensure stable conveying.

[0032] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, a second connecting rod 20 is fixedly connected to the side of the guide wheel frame 18 away from the conveying mechanism. The second connecting rod 20 is inserted laterally into the inkjet chamber 2 and fixedly connected to the limiting cover 4, thereby achieving a stable connection and ensuring that the relative positions of the second guide tube 19, the limiting cover 4, and the inkjet gun 3 remain unchanged.

[0033] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the conveyor platform 1 is divided into two parallel layers, and the two layers of conveyor platform 1 are fixedly connected by inclined plate 21. The bottom end of the column 7 is inserted and fixed between the two layers of conveyor platform 1 to achieve a stable connection of the column 7 and avoid affecting the conveying and causing positional deviation.

[0034] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
