Description

Technical Field

[0001] The present application relates to the technical field of production of pipe pile products, and particularly to a marking device. Background Art

[0002] With the rapid development of China's economy, pipe piles are required for the foundation of railways, highways, bridge buildings, etc. Therefore, the demand for pipe piles has increased significantly. In order to trace the origin of the produced pipe piles, it is usually necessary to mark on the outer surface of the pipe piles, that is, to mark information such as production date, manufacturer, national standard number, size specification, etc. on the outer surface of the pipe piles.

[0003] The existing marking work is usually completed manually. Specifically, usually a template is made in advance, and then marking is carried out by manually brushing ink. This is not only time-consuming and laborious, but also has a large positioning error in manual lettering, poor uniformity, resulting in uneven appearance quality and affecting the brand image. In addition, most of the marking devices on the market use lasers to directly mark on the outer wall of the pipe piles. However, since the color of the pipe piles is similar to the color of the marked signs, it is relatively laborious for people to observe, and the signs may become blurred after the pipe piles are placed for a long time, making it impossible to trace the origin. Summary of the Utility Model

[0004] Based on this, the purpose of the present application is to provide a marking device to solve the problems of time-consuming and laborious existing marking methods, poor uniformity of the marked signs, and blurred signs.

The first mounting plate is connected to the mounting seat. The second mounting plate is connected to the bottom side of the first mounting plate through a second elastic element. The template is connected to the bottom side of the second mounting plate.

[0016] In one embodiment, a first detection component is further provided on the base. The first detection component includes a first emitting member, a receiving member and a first detection element communicatively connected to the receiving member. The first detection element is used to detect whether the to-be-marked part blocks the light emitted by the first emitting member to the receiving member, so as to judge whether the to-be-marked part is placed below the marking assembly.

[0017] In one embodiment, a second detection component is further provided on the base. The second detection component includes a second emitting member and a second detection element which are communicatively connected to each other. The second emitting member is used to emit a signal to the to-be-marked part, and the second detection element is used to obtain the diameter of the to-be-marked part according to the signal.

Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0029] In this application, unless otherwise clearly defined or limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In this application, unless otherwise clearly defined or limited, if there is a description such as the first feature being "on" or "under" the second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0032] This application provides a marking device, where the marking device is used to print marks on the workpiece to be marked, such as information such as production date, manufacturer, national standard number, size specification, etc., to facilitate the traceability of the workpiece to be marked.

[0033] Taking the workpiece to be marked as a pipe pile for construction as an example, the structure of the marking device in this application will be described below. It can be understood that in other embodiments, the marking device of this application is not limited to only being applicable to marking pipe piles, and can also be used to mark any workpiece to be marked, which is not limited here.

[0034] Figure 1The marking device 10 provided by an embodiment of the present application is shown. The marking device 10 provided by the embodiment of the present application includes a base 100, a moving module 200, a marking component 300, and a control unit 400. Among them, the moving module 200 is arranged on the base 100, the control unit 400 is communicatively connected to the moving module 200, and the marking component 300 is arranged on the moving module 200. The control unit 400 is used to control the moving module 200 to drive the marking component 300 to move along the vertical direction (the Z direction shown in the figure), or the first horizontal direction (the X direction shown in the figure), or the second horizontal direction perpendicular to the first horizontal direction (the Y direction shown in the figure), so that the marking component 300 can form a specific mark on the outer surface of the pipe pile.

[0035] Specifically, in one embodiment, as Figure 2 shown, the moving module 200 is a three-axis module, which includes a column 210, an X-axis module 220, a Y-axis module 230, and a Z-axis module 240. Among them, the column 210 is arranged on the base 100, the Z-axis module 240 is movably arranged on the column 210 along the vertical direction, the X-axis module 220 is movably arranged on the Z-axis module 240 along the first horizontal direction, and the marking component 300 is movably arranged on the Y-axis module 230 along the second horizontal direction; the Z-axis module 240 is used to drive the X-axis module 220, the Y-axis module 230, and the marking component 300 to move along the vertical direction together, the X-axis module 220 is used to drive the Y-axis module 230 and the marking component 300 to move along the first horizontal direction together, and the Y-axis module 230 is used to drive the marking component 300 to move along the second horizontal direction.

[0036] More specifically, in one embodiment, the Z-axis module 240 includes a mounting base 241 and a driving source 242. Among them, the mounting base 241 is movably connected to the column 210 along the vertical direction, and the driving source 242 is arranged on the mounting base 241. Exemplarily, the driving source 242 is a motor, the output shaft of which is connected with a gear, and a rack arranged along the vertical direction is arranged on the column 210, and the rack meshes with the gear. In this way, the mounting base 241 is movably arranged on the mounting base 241 through the meshing of the gear and the rack. When the driving source 242 drives the output shaft to rotate around its central axis, the gear can move along the rack, thereby driving the mounting base 241, the X-axis module 220, the Y-axis module 230, and the marking component 300 to move along the vertical direction together.

[0037] Similarly, the X-axis module 220 and the Y-axis module 230 also include a mounting base and a driving source arranged on the mounting base, and their structures are similar to those of the Z-axis module 240. Under the control of the control unit 400, the mounting base of the X-axis module 220, the Y-axis module 230, and the marking component 300 can move along the first horizontal direction together, or the marking component 300 can move alone along the second horizontal direction, which will not be elaborated in detail here.

[0038] It can be understood that the structure of the moving module 200 is not limited to the structure of the embodiment shown in the figure. For example, it can also be a structure in which multiple robotic arms are rotatably connected end to end, and the marking component 300 is arranged on the robotic arm at the outermost end, which can also realize the movement of the marking component 300 in multiple degrees of freedom in three-dimensional space for marking.

[0039] Please refer to Figure 2 and Figure 3 , in the structure of the marking component 300, the marking component 300 includes an inkjet head 310 and a marking head 320. The inkjet head 310 is used to jet ink onto the surface of the pipe pile to form an inkjet area, and the marking head 320 is used to etch (that is, remove the ink marks according to the set trajectory, such as emitting a laser for etching) in the inkjet area according to the trajectory set by the control unit 400 to form a specific mark in the inkjet area.

[0040] In this way, by using the control unit 400 to set the trajectory and adopting the method of first jetting ink and then etching for marking, compared with the method of manual ink brushing for marking, the marking efficiency can be effectively improved, and the marks formed by marking are formed on the black inkjet area, and the marks are clearly visible, overcoming the problems of difficult observation and unclear handwriting, resulting in the inability to trace the parts to be marked.

[0041] Furthermore, in a preferred embodiment, a template 500 is further provided on the moving module 200. A hollow area 501 is opened through opposite sides of the template 500. The hollow area 501 is configured to enable the inkjet head 310 to form a pattern on the surface of the pipe pile that is consistent with the contour of the hollow area 501 when jetting ink onto the pipe pile. This can make the shapes of the inkjet marks uniform and avoid uneven appearance quality of the marks. Specifically, the template 500 is connected to the mounting base 241 of the Z-axis module 240. Therefore, when the mounting base 241 moves in the vertical direction, the template 500 can move in the vertical direction together with the X-axis module 220, the Y-axis module 230, and the marking component 300, so that the template 500 can fit the surface of the pipe pile, and the inkjet marks can be more consistent with the contour of the hollow area 501 when jetting ink on the surface of the pipe pile, improving the quality of the inkjet marks.

[0042] Even further, in an even better implementation manner, in order to fix the template 500 on the pipe pile when it fits the pipe pile and prevent it from moving randomly and affecting the marking quality, two clamping members 600 are provided at intervals at the bottom of the template 500. The clamping members 600 are used to abut against the pipe pile in the radial direction of the pipe pile to fix the template 500 on the pipe pile and prevent the pipe pile from moving randomly.

[0043] It should be noted that the template 500 has a certain elasticity and will warp. If the template 500 cannot fit closely to the surface of the pipe pile, it will also affect the marking quality, such as defects like uneven edges of the inkjet area. Therefore, in order to reduce the warping of the template 500 so that it can better fit the surface of the pipe pile and eliminate the occurrence of this defect, in one embodiment, the Z-axis module 240 further includes a connection component 243. The connection component 243 is arranged on the mounting base 241, and the template 500 is arranged on the bottom side of the connection component 243 and close to the marking component 300. Each clamping component 600 at the bottom of the template 500 is respectively connected to the connection component 243 through a first elastic element 700 (such as a spring), and the first elastic element 700 is configured to provide an elastic force to prevent the template 500 from bending.

[0044] In this way, precisely because of the elastic force provided by the first elastic element 700 to pull the template 500, the template 500 will not bend naturally, so that it can fit more closely to the surface of the pipe pile, achieving the purpose of ensuring the inkjet effect.

[0045] In terms of the structure of the connection component 243, the connection component 243 includes a first mounting plate 2431 and a second mounting plate 2432 which are arranged at intervals. The first mounting plate 2431 is connected to the mounting base 241, and the second mounting plate 2432 is connected to the bottom side of the first mounting plate 2431 through a second elastic element 2433 (such as a spring). The template 500 is connected to the bottom side of the second mounting plate 2432 through the clamping component 600 and the first elastic element 700. In this way, precisely because the second elastic element 2433 is provided, when the template 500 contacts the pipe pile, the contact between the template 500 and the pipe pile is not a hard contact but has a certain buffer. In this way, even when there are errors in the radial dimensions of the pipe piles of the same batch specification, it can ensure a good fit between the template 500 and the pipe pile.

[0046] It can be understood that the Z-axis module 240 can also only set the mounting base 241 without setting the connection component 243. However, as described above, setting the connection component 243 can make the template 500 have a certain buffer when contacting the pipe pile, so it has the best technical effect.

[0047] Please continue to refer to Figure 1, in some embodiments, a first detection component 800 is further provided on the base 100. The first detection component 800 includes a first emitter, a receiver, and a first detection element communicatively connected to the receiver. The first detection element is used to detect whether the pile tube blocks the light emitted by the first emitter to the receiver, so as to determine whether the pile tube is placed below the marking component 300. When the receiver can receive the light emitted by the first emitter, it indicates that the pile tube is not below the marking component 300; when the receiver cannot receive the light emitted by the first emitter, it indicates that the light is blocked by the pile tube, indicating that the pile tube is located below the marking component 300.

[0048] Further optionally, a second detection component 900 is also provided on the base 100. The second detection component 900 includes a second emitter and a second detection element that are communicatively connected to each other. The second emitter is used to emit a signal to the pile tube, and the second detection element is used to obtain the diameter of the pile tube according to the signal.

[0049] In addition, in order to automatically transport the pile tube to below the marking component 300 and transport the marked pile tube to the next station after marking to form an automated assembly line operation, as shown in combination with Figure 1 and Figure 4 , a first conveying mechanism 1000 and a second conveying mechanism 1100 are further provided on the base 100. The first conveying mechanism 1000 includes at least two conveying rollers 1010 arranged at intervals along the first horizontal direction. The conveying rollers 1010 can rotate around their own central axes and can move in the vertical direction, so that the conveying rollers 1010 can convey the pile tube along the first horizontal direction to below the marking component 300 and lift the pile tube to make the pile tube close to the marking component 300 for easy marking; the second conveying mechanism 1100 is arranged between any two adjacent conveying rollers 1010, and it includes a support seat 1110 and a conveying trolley 1120. The conveying trolley 1120 can move along the second horizontal direction on the support seat 1110 to convey the pile tube away from the marking component 300. And optionally, there are multiple conveying trolleys 1120, and each conveying trolley 1120 is connected to a chain that moves in a circumferential cycle, so that each conveying trolley 1120 can return to its original position to carry the subsequent marked pile tubes after conveying the marked pile tube to the next station, thus realizing the recycling of the conveying trolley 1120.

[0050] The following will further introduce the process of marking the pile tube using the marking device 10 described in the above embodiments in combination with Figures 1 to 4 :

[0051] First, after the first conveying mechanism 1000 conveys the pile tube in place, the control unit 400 issues a marking task, and the Z-axis module 240 of the moving module 200 drives the template 500 and the marking component 300 to move downward in the vertical direction, so that the template 500 is close to and fits the pile tube.

[0052] Then, the X-axis module 220 and the Y-axis module 230 of the moving module 200 drive the inkjet head 310 of the marking assembly 300 to move along the first horizontal direction or the second horizontal direction respectively and pass through the hollow area 501 of the template 500 to perform inkjet on the surface of the pipe pile, so that the pattern of the inkjet area formed on the surface of the pipe pile is consistent with the contour of the hollow area 501.

[0053] Next, the X-axis module 220 and the Y-axis module 230 drive the marking head 320 of the marking assembly 300 to move along the first horizontal direction or the second horizontal direction according to the trajectory set by the control unit 400, and etch in the inkjet area formed in the previous step, so as to be able to form specific marks in the inkjet area.

[0054] Finally, the second conveying mechanism 1100 conveys the pipe pile after marking along the second horizontal direction to the next station, and the template 500 and the marking assembly 300 return to their original positions under the drive of the Z-axis module 240, thus completing the entire marking process.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
