Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a device for creating an imitation marble pattern on the surface of acrylic sheets. Background Technology

[0002] Acrylic sheets are a type of transparent polymer plastic that can be widely used as a glass alternative in advertising displays, architectural decoration, handicrafts, and industrial applications.

[0003] Nowadays, with the upgrading of consumer demand, ordinary acrylic sheets can no longer meet the market's pursuit of high-end visual effects. Therefore, many manufacturers now paint marble-like patterns on the surface of acrylic sheets. By imitating the patterns of natural marble, acrylic sheets combine the high-end visual effect of natural stone with their own practical characteristics, thereby enhancing the added value and market competitiveness of the products.

[0004] However, existing processing methods mostly employ template pressing, manual brushing, or robotic drawing to achieve texture formation. Among these, robotic drawing technology, due to its rigid trajectory control, is prone to problems such as blurry textures and insufficient depth, potentially failing to achieve a natural simulation of marble and thus affecting product quality. Therefore, this utility model proposes a marble-pattern imitation device for acrylic sheet surfaces to effectively solve the aforementioned drawbacks. Utility Model Content

[0005] The purpose of this utility model is to provide a device for imitating marble patterns on acrylic sheet surfaces, in order to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a device for imitating marble patterns on the surface of acrylic sheet, including a robotic arm execution unit and a material pen. The material pen is flexibly connected to the control end of the robotic arm execution unit through a soft floating connection component. The material pen can be raised, lowered, or swung at the control end of the robotic pen execution unit to draw imitation marble patterns.

[0007] Optionally, the robotic arm execution unit includes at least two sets of robotic arm bodies, and the material pen is detachably connected to the movable end of the robotic arm body.

[0008] Optionally, the movable end of the robotic arm body is fixedly provided with a clamp, and a fixed tube sleeve is clamped and fixed on the clamp. The clamp has a clamping part adapted to the shape of the fixed tube sleeve. The fixed tube sleeve is fixedly assembled on the clamp through the clamping part, and the material pen is flexibly connected to the fixed tube sleeve.

[0009] Optionally, the fixed tube sleeve has a tubular structure, the material pen penetrates the inner side of the fixed tube sleeve along the axial direction of the fixed tube sleeve, and the material pen is detachably connected to the fixed tube sleeve through a soft floating connection assembly.

[0010] Optionally, the soft floating connection assembly includes a soft floating head, which has a spherical cavity structure and is made of elastic material. The soft floating head is fixedly and detachably connected to one end of the fixed tube sleeve. The soft floating connection assembly is fixedly sleeved on the outside of the material pen, and the side of the soft floating connection assembly away from the fixed tube sleeve is fixedly connected to the material pen.

[0011] Optionally, the diameter of the material pen is smaller than the diameter of the fixed tube sleeve.

[0012] Compared with the prior art, this utility model provides a device for simulating marble patterns on acrylic sheet surfaces, which has the following beneficial effects:

[0013] 1. This utility model sets a fixed tube sleeve at the control end of the robotic arm, and connects the fixed tube sleeve and the material pen through a soft floating head. By utilizing the elasticity and deformation capability of the soft floating head itself, the material pen can move axially within the fixed tube sleeve to achieve lifting and lowering. When the surface of the acrylic sheet is uneven, the material pen can be lifted and lowered at any time under the action of the soft floating head to prevent the material pen from getting stuck and ensure the smoothness and natural texture of the texture lines.

[0014] 2. In this utility model, the diameter of the material pen is smaller than the diameter of the fixed tube sleeve, so that there is a certain cavity gap between the material pen and the inner wall of the fixed tube sleeve, allowing the material pen to swing inside the fixed tube sleeve. When the material pen moves along an arc or zigzag trajectory, the soft floating head can drive the material pen to make slight offsets and angle adjustments, avoiding the hard edges and sharp corners of the texture caused by the mechanical rigidity of the material pen, making the drawn texture closer to the natural texture.

[0019] 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 protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 3 A device for creating a marble-like pattern on an acrylic sheet surface includes a robotic arm execution unit and a material pen 1. The material pen 1 is flexibly connected to the control end of the robotic arm execution unit via a soft floating connection component 2, so that the material pen 1 can have a certain degree of freedom of movement at the control end of the robotic arm execution unit, allowing the material pen 1 to rise, fall, or swing at the control end of the robotic pen execution unit to draw a marble-like pattern.

[0021] Furthermore, the robotic arm execution unit includes at least two sets of robotic arm bodies 3, with the material pen 1 detachably connected to the movable end of the robotic arm body 3. The robotic arm body 3 is automatically controlled by a PLC controller to precisely control the height of the material pen 1 and the trajectory it draws, ensuring that the contact state between the material pen 1 and the board material and the material accumulation shape conform to the natural feel of the natural texture.

[0022] On the other hand, the end of the material pen 1 furthest from the pen tip is connected to a feeding pipe for inputting materials such as color paste and pigment. A pressure pump is installed on the feeding pipe, which is also electrically connected to a PLC controller (not shown in the attached figure) to control the direction of the pigment and the amount of pigment output, so that the texture color has different shades and is more in line with the natural feel of natural texture.

[0023] In this embodiment, a clamp 4 is fixedly provided at the movable end of the robotic arm body 3. A fixed tube sleeve 5 is clamped and fixed on the clamp 4. The clamp 4 has a clamping part adapted to the shape of the fixed tube sleeve 5. The fixed tube sleeve 5 is fixedly assembled on the clamp 4 through the clamping part, and the material pen 1 is flexibly connected to the fixed tube sleeve 5. The movable end of the robotic arm body 3 is fixedly connected to a mounting plate 301, and at least two clamps 4 are fixedly installed on the mounting plate 301 to ensure that the fixed tube sleeve 5 can remain stable and not shake after being clamped and fixed.

[0024] On the other hand, the clamp 4 can be equipped with either manual or automatic grippers. The automatic grippers are electrically connected to the PLC controller, allowing the opening and closing of the clamp 4 to be automatically controlled. Furthermore, in this embodiment, the fixed pipe sleeve 5 has a tubular structure, and the main body of the clamp 4 consists of two relatively movable grippers. The opposing surfaces of the two grippers are arc-shaped, so that when the two grippers approach each other, they can fit against the outer wall of the fixed pipe sleeve 5, making the clamping force more stable.

[0025] Furthermore, the material pen 1 extends through the inner side of the fixed tube sleeve 5 along the axial direction of the fixed tube sleeve 5. The material pen 1 is detachably connected to the fixed tube sleeve 5 through the soft floating connection component 2, so that when the robotic arm body 3 controls the movement of the fixed tube sleeve 5, it will drive the material pen 1 to move together.

[0026] The following is a detailed description of the soft floating connection component 2:

[0027] The soft floating connection assembly 2 includes a soft floating head 201, which has a spherical cavity structure. The soft floating head 201 is made of elastic materials such as polyurethane elastomer or silicone and has a certain deformation capability, enabling the material pen 1 to obtain a certain range of adaptive fine-tuning motion space. The soft floating head 201 is fixedly and detachably connected to one end of the fixed tube sleeve 5. The soft floating connection assembly 2 is fixedly sleeved on the outside of the material pen 1, and the side of the soft floating connection assembly 2 away from the fixed tube sleeve 5 is fixedly connected to the material pen 1.

[0028] Among them, such as Figure 3 As shown, the soft floating head 201 has openings at both the top and bottom. The material pen 1 passes through the soft floating head 201, and an upper flange 203 and a lower flange 202 are fixedly connected to the openings at the top and bottom of the soft floating head 201, respectively. A first flange protrudes outward from the outer side of the fixed pipe sleeve 5 near the soft floating head 201. The lower flange 202 is fixedly connected to the first flange by bolts or other connecting parts, so that the soft floating head 201 is fixed to one end of the fixed pipe sleeve 5. A second flange protrudes outward from the outer side of the material pen 1 near the upper flange 203. The second flange is fixedly connected to the upper flange 203 by bolts or other connecting parts, so that the material pen 1 and the soft floating head 201 are fixedly connected to the end away from the fixed pipe sleeve 5.

[0029] Because the soft floating head 201 has a certain degree of elasticity and deformation capability, when the pen tip 1 draws patterns on the acrylic sheet, if it encounters a protrusion on the surface of the sheet, the pen tip 1 will be pushed away from the sheet. The pen tip 1 pulls the soft floating head 201 upward through the upper flange 203, causing the soft floating head 201 to deform, so that the pen tip 1 can smoothly glide over the protrusion on the surface of the sheet, avoiding the pen tip 1 getting stuck, and making the drawn patterns closer to nature.

[0030] Meanwhile, the diameter of the material pen 1 is smaller than the diameter of the fixed sleeve 5. Specifically, in this embodiment, the diameter of the material pen 1 is 1.5-3cm, and the diameter of the fixed sleeve 5 is 4-5cm. Therefore, the material pen 1 can swing around the position of the upper flange 203 within the fixed sleeve 5. When the material pen 1 draws along irregular lines such as arcs and zigzags, the soft floating head 201 can produce flexible deformation, causing the material pen 1 to adjust the contact angle and distance with the plate in real time. This avoids the material pen 1 from having hard edges and sharp corners due to mechanical rigidity, making the drawn texture more natural.

[0031] The working principle and usage process of this utility model are as follows: First, the fixed tube sleeve 5 is clamped and fixed by the clamp 4. Then, the material pen 1 is passed through the fixed tube sleeve 5 and the soft floating head 201. Using bolts and other connecting parts, the lower flange 202 and the fixed tube sleeve 5 are fixedly connected, and the upper flange 203 and the material pen 1 are fixedly connected, so that the material pen 1 and the fixed tube sleeve 5 are flexibly connected by the soft floating head 201. Subsequently, the PLC controller can control the robotic arm body 3 to drive the material pen 1 to move, thereby making the material pen 1 draw patterns on the surface of the acrylic sheet. Through the elasticity and deformation capability of the soft floating head 201, the material pen 1 can have a certain range of adaptive fine-tuning motion space when encountering the protrusions and irregular trajectories on the surface of the sheet, making the drawn patterns closer to natural.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
