Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to an automatic marking device for a heat treatment line and its working method. Background Technology

[0002] Currently, due to the specific mechanical performance requirements of die-cast structural components, these requirements can only be met through post-die-casting heat treatment. To distinguish whether a product has undergone heat treatment, markings need to be drawn on the product. After high-temperature heat treatment, the markings will change color with temperature changes. By distinguishing the color of the markings, it is clear whether the product has undergone heat treatment. However, the biggest problem with this process is that the drawing is entirely manual, which is unreliable.

[0003] Because the lines are drawn manually, several problems have been identified in practice. First, due to worker negligence, omissions in the lines are frequent. If these omitted lines are used in the heat treatment process, and we cannot distinguish whether they have undergone heat treatment, they must be scrapped, resulting in significant waste. Second, standardizing the lines is difficult. Defining the exact location and length of the lines on the product surface is challenging. Even if the calculations are defined, the increased variety of product types places extremely high demands on the operator; slight errors in memory can lead to inconsistencies in line length and placement.

[0004] Therefore, how to standardize product marking and reduce the chances of mismarking or omissions is one of the problems that marking devices should solve. Utility Model Content

[0024] Currently, due to the specific mechanical performance requirements of die-cast structural components, these requirements can only be met through post-die-casting heat treatment. To distinguish whether a product has undergone heat treatment, markings need to be drawn on the product. After high-temperature heat treatment, the markings will change color with temperature changes. By distinguishing the color of the markings, it is clear whether the product has undergone heat treatment. However, the biggest problem with this process is that the drawing is entirely manual, which is unreliable.

[0025] Because the lines are drawn manually, several problems have been identified in practice. First, due to worker negligence, omissions in the lines are frequent. If these omitted lines are used in the heat treatment process, and we cannot distinguish whether they have undergone heat treatment, they must be scrapped, resulting in significant waste. Second, standardizing the lines is difficult. Defining the exact location and length of the lines on the product surface is challenging. Even if the calculations are defined, the increased variety of product types places extremely high demands on the operator; slight errors in memory can lead to inconsistencies in line length and placement.

[0026] Therefore, how to standardize product marking and reduce the chances of mismarking or omissions is one of the problems that marking devices should solve.

[0027] To address this issue, this application proposes an automatic marking device for heat treatment lines. A translation component brings the drawing pen closer to the workpiece, and a telescopic mechanism allows the pen tip to rest on the workpiece. The reciprocating movement of a lifting drive component then draws lines on the workpiece surface, resulting in more standardized lines. Furthermore, by incorporating sensors, the distance between the pen holder and the workpiece can be accurately detected, preventing missed or incorrect markings.

[0028] Reference Figure 1The automatic marking device for heat treatment lines in this embodiment includes a lifting assembly 100, a translation assembly 200, a drawing pen assembly 300, and a sensor (not shown). The lifting assembly 100 adjusts the height of the drawing pen assembly 300, the translation assembly 200 adjusts the distance between the drawing pen assembly 300 and the workpiece, the drawing pen assembly 300 extends to contact the workpiece surface, and the sensor detects whether a predetermined distance has been reached between the drawing pen assembly 300 and the workpiece. When the pen tip contacts the workpiece, the lifting assembly 100 moves back and forth to drive the drawing pen to draw lines on the workpiece surface, thereby automatically completing the drawing process.

[0029] Specifically, the lifting assembly 100 includes a base 110, a movable seat 120, and a lifting drive 130. The lifting drive 130 is connected to the base 110 and can drive the movable seat 120 along a first direction (see reference). Figure 1 The translation assembly 200 includes a slider 210 and a translation drive (not shown in the figure). The slider 210 is slidably connected to the movable seat 120 and can move in the second direction (refer to the z-direction). Figure 1 The slider 210 slides in the x-direction and the translation drive is mounted on the movable seat 120 and can drive the slider 210 to move.

[0030] Reference Figure 2 The brush assembly 300 includes a brush holder 310, a telescopic mechanism 320, and a brush 330. The brush holder 310 is connected to the slider 210. The telescopic mechanism 320 is mounted on the brush holder 310 and can extend. The brush 330 is mounted on the output end of the telescopic mechanism 320, so that the telescopic mechanism 320 can extend the brush 330 and contact the workpiece surface.

[0031] The sensor is mounted on the slider 210 to detect the distance between the brush holder 310 and the workpiece, thereby enabling closed-loop control of the translation drive of the brush holder 310 by the translation component 200.

[0032] The lifting drive 130 moves back and forth along the first direction, which enables the pen 330 to draw lines on the surface of the workpiece.

[0033] The working principle of this automatic marking device for the heat treatment line is as follows: The lifting component 100 can adjust the height of the drawing pen component 300, the translation component 200 can adjust the position of the drawing pen component 300 on the horizontal plane, and the sensor can continuously monitor the distance between the drawing pen component 300 and the workpiece, thereby ensuring that the drawing pen component 300 reaches a predetermined position close to the workpiece. Then, the telescopic mechanism 320 in the drawing pen component 300 extends the drawing pen 330, and the tip of the drawing pen 330 contacts the surface of the workpiece. Subsequently, the lifting component 100 drives the drawing pen 330 to move back and forth along the first direction, thereby drawing lines on the surface of the workpiece.

[0034] Furthermore, the lifting drive component 130, the translation drive component, and the telescopic mechanism 320 can be hydraulic telescopic rods, pneumatic telescopic rods, or screw mechanisms, or other drive mechanisms capable of linear motion, which will not be elaborated here.

[0035] Furthermore, the brush assembly 300 also includes a rotating mechanism 340, which is mounted on the slider 210. The brush holder 310 is mounted on the output end of the rotating mechanism 340. The output end of the rotating mechanism 340 can rotate, thereby changing the orientation of the brush holder 310 and making adaptive adjustments according to the surface of different workpieces.

[0036] Furthermore, the rotating mechanism 340 can be driven by a motor directly, by a motor through a transmission mechanism, or by a cylinder turntable, etc., which will not be described in detail again.

[0037] Furthermore, the brush assembly 300 also includes a brush cap 350, which is mounted on the slider 210. The tip of the brush 330 can extend into the brush cap 350, so that when the automatic marking device of this heat treatment line is not in operation, the tip of the brush 330 can extend into the brush cap 350 to prevent the ink from drying out and keep the brush tip moist.

[0038] Furthermore, the pen cap 350 is mounted on the side of the brush holder 310, the rotating mechanism 340 can drive the brush holder 310 to rotate so that the brush 330 is aligned with the pen cap 350, and the telescopic mechanism 320 can drive the brush 330 to extend so that its tip extends into the pen cap 350.

[0039] Optionally, the brush holder 310 includes a brush base 311 and a flip plate 312. One end of the flip plate 312 is hinged to the brush base 311. A telescopic mechanism 320 is mounted on the flip plate 312. The flip plate 312 can rotate around its hinge axis with the brush base 311, thereby changing the pitch angle of the brush 330 to adapt to workpieces with different surfaces.

[0040] Specifically, the brush base 311 has an arc-shaped adjustment groove on its side, and the flip plate 312 has a threaded hole corresponding to the adjustment groove on its side. The fixing bolt can pass through the adjustment groove, extend into the threaded hole, and be tightened, thereby fixing the tilt angle of the flip plate 312 by the bolt.

[0041] Furthermore, the translation component 200 also includes a slide rail 220, which is mounted to the movable seat 120. The slider 210 slides in the slide rail 220, thereby reducing the movement resistance of the slider by setting the slide rail.

[0042] Furthermore, the lifting assembly 100 also includes a guide rail 140, which is fixed to the base 110 and extends along the first direction. The movable seat 120 is slidably connected to the guide rail 140, thereby restricting the sliding direction of the movable seat 120 by the guide rail 140, so that it can only slide along the first direction, and preventing the movable seat 120 from deviating during the lifting process.

[0043] Furthermore, the base 110 has a mounting slot through which bolts can pass so that the base 110 can be connected to an external device.

[0044] The following describes the working method of this automatic marking device for the heat treatment line, including the following steps: S100. The lifting drive 130 drives the movable seat 120 to move along the first direction so that the pen 330 reaches a predetermined height; S200. The translation drive drives the pen holder 310 to move along the second direction until the sensor is triggered, at which point the distance between the pen 330 and the workpiece reaches the predetermined distance. S300. The telescopic mechanism 320 drives the pen 330 to extend, so that the tip of the pen 330 contacts the workpiece; S400. The lifting drive 130 drives the movable seat 120 to move back and forth in the first direction so that the pen 330 can sweep across the surface of the workpiece to complete the drawing work. S500. The telescopic mechanism 320 drives the pen 330 to retract, and the pen 330 moves away from the workpiece; S600. The translation drive drives the pen holder 310 to move along the second direction, and the pen holder 310 moves away from the workpiece.

[0045] When the next workpiece moves to the automatic marking device of this heat treatment line, the above operation is repeated to achieve the alternating marking of multiple workpieces.

[0046] Furthermore, in some embodiments, the brush assembly 300 further includes a rotating mechanism 340 and a brush cap 350, both mounted on the slider 210, and a brush holder 310 mounted on the output end of the rotating mechanism 340. After the automatic marking device for the heat treatment line completes the marking work, the rotating mechanism 340 can drive the brush holder 310 to rotate so that the brush 330 is aligned with the brush cap 350, and the telescopic mechanism 320 drives the brush 330 to extend so that the tip of the brush 330 extends into the brush cap 350, reducing the drying of the ink at the brush tip.

[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application 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 this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
