Description

Technical Field

[0001] This utility model relates to the field of workpiece marking technology, and in particular to a marking and painting device. Background Technology

[0002] Currently, when marking workpieces with paint, the operator typically holds the workpiece in one hand and a paintbrush in the other to mark the workpiece's circumferential surface. Because both the workpiece and the paintbrush are held by hand, the marking accuracy and consistency are poor (the operator first applies paint to one side of the workpiece's surface, then to the other), easily resulting in uneven marking (it's difficult to create a uniform and regularly shaped marking surface on the workpiece's circumference) and inaccurate positioning. Furthermore, prolonged hand-holding of the workpiece and paintbrush for marking can easily lead to operator fatigue, thus affecting work efficiency and quality, especially when marking large batches of workpieces, further exacerbating these issues.

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0055] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0057] Currently, when marking workpieces with paint, the operator typically holds the workpiece in one hand and a paintbrush in the other to mark the workpiece's circumferential surface. Because both the workpiece and the paintbrush are held by hand, the marking accuracy and consistency are poor (the operator first applies paint to one side of the workpiece's surface, then to the other), easily resulting in uneven marking (it's difficult to create a uniform and regularly shaped marking surface on the workpiece's circumference) and inaccurate positioning. Furthermore, prolonged hand-holding of the workpiece and paintbrush for marking can easily lead to operator fatigue, thus affecting work efficiency and quality, especially when marking large batches of workpieces, further exacerbating these issues.

[0058] Based on this, refer to Figures 1-11 As shown, this application embodiment provides a marking and painting device with a Z-direction extending along its height direction for marking and painting the peripheral surface of a workpiece 8. The marking and painting device includes a painting component 1 for marking and painting the peripheral surface of the workpiece 8. The painting component 1 has a painting groove 11. In the Z-direction, the painting groove 11 has a first open state and a second closed state, that is, the painting groove 11 can be opened or closed along the Z-direction. When the painting groove 11 is in the first state, the painting groove 11 is in the open state, which is used to allow the workpiece 8 to be marked and painted to be placed into or removed from the painting groove 11. When the painting groove 11 is in the second state, the painting groove 11 is in the closed state, which is used to wrap the peripheral surface of the workpiece 8 placed in the painting groove 11, thereby realizing the marking and painting of the peripheral surface of the workpiece 8.

[0059] It is understood that the cross-section of workpiece 8 in this solution can be of any shape, such as circular, square, or triangular. Of course, the shape of the paint tank 11 should match the shape of the cross-section of workpiece 8. Thus, when workpiece 8 is placed in the paint tank 11, the peripheral surface of workpiece 8 can fit and conform to the paint tank 11, thereby achieving uniform paint marking on the peripheral surface of workpiece 8 and forming a regularly shaped paint marking surface, resulting in a better aesthetic appearance. This effectively avoids the problem of irregular shape and uneven paint application, leading to poor aesthetic appearance, when the operator holds workpiece 8 in one hand and a paint pen in the other to paint marking the peripheral surface of workpiece 8. It also reduces the complexity of the operator's operation, thereby avoiding operator fatigue and ensuring high-efficiency and high-quality completion of the paint marking workpiece 8.

[0060] In this embodiment, after the paint marking on the periphery of the workpiece 8 is completed, the closed paint tank 11 is opened along the Z direction, and then the workpiece 8 with the paint marking completed is removed from the paint tank 11. The operator can then place the new workpiece 8 to be painted into the paint tank 11 to carry out the subsequent paint marking operation.

[0061] Reference Figure 1 , Figure 2 As shown, in one embodiment of this application, the painting component 1 includes a first painting part 12 and a second painting part 13; wherein, the first painting part 12 has a first groove 111 on one side in the Z direction, and the first painting part 12 is fixedly arranged; the second painting part 13 is movable in the Z direction, and the second painting part 13 is disposed on the side of the first painting part 12 where the first groove 111 is provided, the second painting part 13 is located directly above the first painting part 12, and the side of the second painting part 13 facing the first groove 111 has a second groove 112 that cooperates with the first groove 111; the first groove 111 and the second groove 13... Both sides of 112 are connected to the outside. Thus, when the second painting part 13 moves in the Z direction and abuts against the first painting part 12, the second tank 112 and the first tank 111 abut against each other, thereby making the first tank 111 and the second tank 112 combine to form the above-mentioned painting tank 11. At this time, the painting tank 11 is in the second state. The second painting part 13 is driven to move away from the first painting part 12, so that the second painting part 13 and the first painting part 12 are separated, thereby separating and opening the second tank 112 and the first tank 111, so that the painting tank 11 is in the first state.

[0062] In this embodiment, when it is necessary to paint and mark the peripheral surface of the workpiece 8, the second painting part 13 is first driven to move a certain distance away from the first painting part 12, so that the second groove 112 and the first groove 111 are separated, thereby making the painting groove 11 open. Then, the workpiece 8 is placed into the first groove 111 located below (at this time, half of the peripheral surface of the workpiece 8 is in contact with the inner wall of the first groove 111). Then, the second painting part 13 is driven to move towards the first painting part 12 and make the second painting part 13 abut against the first painting part 12. A painting section 12 is provided, which assembles the second tank 112 and the first tank 111 into a painting tank 11 (at this time, the other half of the peripheral surface of the workpiece 8 is in contact with the inner wall of the second tank 112); after the painting tank 11 is closed, the peripheral surface of the workpiece 8 to be marked is covered by the painting tank 11. Then, the peripheral surface of the workpiece 8 can be uniformly painted and marked through the closed painting tank 11, and a regularly shaped painted marking surface is formed on the peripheral surface of the workpiece 8, so that the workpiece 8 has a better aesthetic appearance after the painting and marking is completed.

[0063] Reference Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment of this application, the first painting section 12 and the second painting section 13 have the same structure, and both the first painting section 12 and the second painting section 13 include a cylinder 2 and a coating member 3; wherein, the cylinder 2 has a receiving space, and the receiving space is used to receive a storage component 5 for storing paint; the coating member 3 is located at one end of the cylinder 2 along the Z direction, and a feed port 221 is provided through the cylinder 2 at the end where the coating member 3 is installed along the Z direction, the feed port 221 is used to enable the coating member 3 to contact the storage component 5 located in the receiving space; it can be understood that the coating member 3 at least partially passes through the feed port 221 and extends into the receiving space, thereby achieving contact with the storage component 5, so that the paint coating stored in the storage component 5 is transferred to the coating member 3, and finally the coating member 3 is used to mark the peripheral surface of the workpiece 8 with paint.

[0064] In this embodiment, as Figure 9 As shown, the first groove 111 and the second groove 112 are respectively formed on the corresponding coating member 3. That is, the first groove 111 is formed on the coating member 3 provided on the first painting part 12, and the second groove 112 is formed on the coating member 3 provided on the second painting part 13. When the second painting part 13 and the first painting part 12 abut together, the two coating members 3 abut against each other on one side, thereby causing the second groove 112 and the first groove 111 to be combined to form the above-mentioned painting groove 11. At this time, the two coating members 3 respectively cover the peripheral surface of the workpiece 8 (e.g., Figure 10As shown), the paint stored in the storage component 5 is applied to the peripheral surface of the workpiece 8 by the applicator 3, thereby forming a regularly shaped paint mark on the peripheral surface of the workpiece 8. Since the operator no longer needs to hold a paintbrush to apply the paint, the painting operation can be completed by driving the second painting part 13 toward the first painting part 12 in the Z direction and making the two applicators 3 wrap around the peripheral surface of the workpiece 8, thus ensuring the uniformity of the paint on the surface of the workpiece 8.

[0065] In this embodiment, the painting marking operation on the peripheral surface of the workpiece 8 can be achieved simply by moving the second painting part 13 in the Z direction. Compared with the operator holding the workpiece 8 and painting pen to paint and mark, the labor intensity of the operator is significantly reduced. When the operator holds the painting pen to paint and mark, the painting pen needs to be moved frequently on the peripheral surface of the workpiece 8 to complete the painting action. The operator's repeated execution of the above action will easily lead to fatigue and reduce work efficiency and work quality.

[0066] In this embodiment, the material of the coating component 3 is the same as that of the pen tip of the oil-based pen (made of polymer materials such as plastic and fiber), which can guide the paint through, but can also prevent the paint from flowing out through the coating component 3 in a short time. It has an appropriate porosity, which can both ensure the flow of the paint and control the outflow speed of the paint.

[0067] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, in one embodiment of this application, the cylindrical body 2 includes a first cylindrical body 21 and a second cylindrical body 22; wherein, the outer diameter of the second cylindrical body 22 is slightly smaller than the inner diameter of the first cylindrical body 21, thereby allowing the second cylindrical body 22 to be inserted into the first cylindrical body 21 (e.g., Figure 7 As shown), the aforementioned receiving space is formed inside the second cylinder 22; in the Z direction, one end of the second cylinder 22 extends at least partially outward from the first cylinder 21, for mounting the applicator 3 at the outward-extending end of the second cylinder 22 from the first cylinder 21, while the feed port 221 is provided at the outward-extending end of the second cylinder 22 from the first cylinder 21, and the feed port 221 completely penetrates the outward-extending end of the second cylinder 22 from the first cylinder 21 along the Z direction (e.g., Figure 8 As shown), this allows the coating component 3 to contact the storage component 5 through the feed port 221, so that the paint stored in the storage component 5 can be transferred to the coating component 3 for painting and marking operations; it is understood that the storage component 5 is housed inside the second cylinder 22 (accommodation space), and the second cylinder 22 and the first cylinder 21 are detachably connected, thereby enabling the replacement or replenishment of paint in the storage component 5 housed in the second cylinder 22.

[0068] In this embodiment, the cylinder 2 includes two detachably connected first cylinders 21 and second cylinders 22, which facilitates the operator to replace the storage component 5 or replenish the paint. After long-term use, the residual paint in the storage component 5 will solidify in the containment space, thereby dividing the cylinder 2 into two detachably connected first cylinders 21 and second cylinders 22, which facilitates later maintenance and upkeep.

[0069] Reference Figure 7 , Figure 8 As shown, in one embodiment of this application, the first painting portion 12 and the second painting portion 13 further include an elastic element 4; wherein, the elastic element 4 is housed within the receiving space, that is, inside the second cylinder 22; the elastic element 4 is arranged along the Z direction and can generate compressive elastic deformation along the Z direction, and the elastic element 4 has a first end abutting against the first cylinder 21 and a second end disposed opposite to the first end in the Z direction, such as... Figure 7 As shown, when the second cylinder 22 is inserted into the first cylinder 21 and the two are connected together, the first end of the elastic member 4 abuts against the end of the first cylinder 21 away from the coating member 3, and the second end of the elastic member 4 abuts against the storage component 5, so that the storage component 5 is clamped at the second end and the end of the second cylinder 22 where the material outlet 221 is provided (at this time, the storage component 5 is subjected to an elastic force applied by the elastic member 4 and squeezed towards the material outlet 221).

[0070] In this embodiment, the coating component 3 is arranged along the Z-direction at one end of the second cylinder 22 extending outward from the first cylinder 21. When the coating component 3 is compressed, at least a portion of it can pass through the feed port 221 and enter the receiving space. For example, in this solution, when the material storage component 5 is compressed by external force, it can squeeze out the paint stored inside and transfer it to the coating component 3. Finally, the coating component 3 applies the paint to the peripheral surface area of ​​the workpiece 8. In specific operation, the paint tank 11 is first adjusted to the open state, thereby placing the workpiece 8 into the first tank 111 located below, and then driving... The second painting section 13 moves downward toward the first painting section 12, causing the first tank 111 and the second tank 112 to assemble and cover the peripheral surface of the workpiece 8. Then, the second painting section 13 continues to move downward a certain distance. At this time, the two coating parts 3, which are slidably arranged along the Z direction, are obstructed by the workpiece 8 and slide relative to the corresponding second cylinder 22. This causes the coating parts 3 to enter the receiving space at least partially toward the storage assembly 5 and squeeze the storage assembly 5, so that the paint coating stored in the storage assembly 5 is squeezed out and transferred onto the coating parts 3 for painting and marking operations.

[0071] It is understandable that when the coating part 3 presses against the storage assembly 5, the elastic part 4 will simultaneously undergo a certain degree of compression deformation. After the painting and marking operation of the workpiece 8 is completed, the second painting part 13 is driven to move away from the first painting part 12, thereby separating the two coating parts 3. At this time, the coating part 3 is no longer squeezed by the workpiece 8, and the elastic part 4 restores its deformation and pushes against the storage assembly 5 to drive the coating part 3 to move back to the initial position (complete reset).

[0072] Reference Figure 6 , Figure 8 As shown in one embodiment of this application, the second cylinder 22 extends outward from the first cylinder 21 and has a mounting groove 222. It is understood that a mounting frame (not shown in the figure) is provided at the end of the second cylinder 22 extending outward from the first cylinder 21, and the mounting groove 222 is formed in the mounting frame. The applicator 3 is slidably arranged in the mounting groove 222, and the peripheral sidewall of the applicator 3 contacts and engages with the inner sidewall of the mounting groove 222. This results in a certain frictional resistance between the peripheral sidewall of the applicator 3 and the inner sidewall of the mounting groove 222, which ensures that when the applicator 3 is installed in the mounting groove 222 and is not subjected to external force, it can be stably located in the mounting groove 222 and will not detach from the mounting groove 222. The frictional resistance between the peripheral sidewall of the applicator 3 and the inner sidewall of the mounting groove 222 should not be too large, so that when the applicator 3 is squeezed by the workpiece 8, it can easily move in the mounting groove 222 along the Z direction.

[0073] In this embodiment, the projection of the feed port 221 in the Z direction is denoted as S1, and the projection of the mounting groove 222 is denoted as S2. S2 should be located inside S1, meaning the size of the feed port 221 should be greater than or at least equal to the size of the mounting groove 222. This is to ensure that when the coating component 3 is compressed by the workpiece 8, the workpiece 8 can pass through the feed port 221 and exert a certain degree of compression on the storage assembly 5, thereby allowing the paint stored in the storage assembly 5 to be better transferred to the coating component 3. Figure 7 , Figure 8 In order to ensure that the storage component 5 can be confined within the receiving space and will not detach outward, the projection of the storage component 5 in the Z direction should be greater than the projection of the feed port 221. Thus, when the elastic member 4 abuts against the storage component 5, the other end of the storage component 5 can abut against an area other than the feed port 221, thereby confining the storage component 5 within the receiving space and preventing it from detaching outward.

[0074] Understandably, when it is necessary to replenish the paint, the coating part 3 installed in the mounting slot 222 can be manually removed outwards, and at this time, paint can be replenished into the storage component 5 through the feed port 221.

[0075] Reference Figure 4, Figure 5 As shown, in one embodiment of this application, in the Z direction, the second cylinder 22 extends outward from the first cylinder 21 and is detachably connected to the first cylinder 21 via a connector. A connector is provided on the periphery of the end of the second cylinder 22 extending outward from the first cylinder 21 to realize the connection between the second cylinder 22 and the first cylinder 21. For example, the connector can be a threaded connection, a snap-fit ​​connection or other forms of connection, as long as it can realize the detachable connection between the second cylinder 22 and the first cylinder 21.

[0076] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, in one embodiment of this application, the connector includes an annular structural member 6 and a second threaded portion 211 disposed on the outer periphery of the first cylindrical body 21; wherein, the annular structural member 6 is coaxially fitted onto the periphery of the second cylindrical body 22 extending outward from the end of the first cylindrical body 21, and the inner wall of the annular structural member 6 is spaced apart from the outer periphery of the second cylindrical body 22, such that the gap between them forms a space for inserting the periphery wall of the first cylindrical body 21; as shown Figure 5 As shown, a first threaded portion 61 that mates with the second threaded portion 211 is provided on the inner wall of the annular structural member 6. When it is necessary to connect the first cylinder 21 and the second cylinder 22 into one unit, the second cylinder 22 is inserted into the first cylinder 21 and the second cylinder 22 is screwed on. Thus, the connection between the first cylinder 21 and the second cylinder 22 is achieved through the mate of the second threaded portion 211 and the first threaded portion 61.

[0077] In this embodiment, as Figure 7 As shown, the inner wall of the annular structural member 6 is fixedly connected to the outer peripheral wall of the second cylinder 22 via an annular plate (not shown in the figure) coaxially connected to it. The annular plate can be integrally formed with the second cylinder 22 or separately formed and then welded together. The annular plate ensures a certain gap between the inner wall of the annular structural member 6 and the outer peripheral wall of the second cylinder 22, allowing the first cylinder 21 to be inserted. When the second cylinder 22 is screwed on, it is until the end of the first cylinder 21 abuts against the annular plate (e.g., ...). Figure 7 As shown in the figure, you can stop turning. At this time, the first cylinder 21 and the second cylinder 22 have achieved a stable connection.

[0078] Reference Figure 7 , Figure 8As shown in one embodiment of this application, the storage component 5 is an ink-absorbing cotton, used to store a certain amount of paint to ensure a continuous supply of paint during the marking process; the ink-absorbing cotton is at least one of polyester fiber, non-woven fabric, and melamine foam; wherein, polyester fiber has high water absorption, can absorb a large amount of paint, maintain the marking requirements for a long time, and is corrosion-resistant, suitable for different types of paint; non-woven fabric has a high-density structure, which can quickly absorb and lock in the paint.

[0079] In this embodiment, the ink-absorbing cotton will become saturated after a period of use and needs to be replaced regularly to maintain the best performance of the marking device. Therefore, the first cylinder 21 and the second cylinder 22 are disassembled and opened to remove and replace the ink-absorbing cotton.
