Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board processing, in particular to a precise wetting device for corrugated board. Background Art

[0002] In the process of producing corrugated board, it is usually necessary to apply glue or perform printing on its surface, and then dry it through a drying device. However, the surface of the dried board is prone to cracking, which will affect the quality of the board. To avoid this situation, it is often necessary to wet the board.

[0003] The traditional wetting method is usually to spray water mist on the surface of the corrugated board, but this method has some problems. First of all, not all positions on the surface of the corrugated board need to be wetted, and excessive wetting will lead to insufficient hardness of the board, thus affecting the quality of the board. Therefore, a device that can accurately identify dry cracks and perform local wetting treatment is needed. Summary of the Utility Model

[0004] The utility model aims at the technical problems existing in the prior art, and provides a precise wetting device for corrugated board to solve the problem that not all positions on the surface of the corrugated board need to be wetted, and excessive wetting will lead to insufficient hardness of the board, thus affecting the quality of the board.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: a precise wetting device for corrugated board, comprising:

[0006] A conveying mechanism for conveying the corrugated board;

[0007] A gantry frame arranged directly above the conveying mechanism;

[0008] A ccd vision detection component arranged at the bottom of the gantry frame and facing the conveying mechanism, wherein the ccd vision detection component is used to detect and identify dry cracks on the corrugated board;

[0009] A three-axis robotic arm arranged at the top of the gantry frame and electrically connected to the ccd vision detection component;

[0010] A wetting component arranged on the moving end of the three-axis robotic arm. When the ccd vision detection component identifies a dry crack, the three-axis robotic arm drives the wetting component to move to the dry crack area on the corrugated board for wetting treatment.

[0011] The beneficial effects of the utility model are:

[0012] 1) The device introduces CCD vision detection to achieve real-time detection and recognition of dry cracks on the surface of corrugated cardboard. When the dry cracks on the cardboard are recognized, the wetting component is driven by a three-axis robotic arm to accurately position the wetting operation in the dry crack area of the cardboard, rather than the entire cardboard surface. This not only avoids operating on areas that do not require wetting treatment but also avoids excessive wetting, thus protecting the quality of the cardboard. Through precise wetting treatment, the generation of cracks is effectively prevented, the scrap rate in the production process is reduced, and the production efficiency is improved.

[0013] Based on the above technical solution, the present utility model can be further improved as follows.

[0014] Further, the wetting component includes a roller, a wet sponge, and two hanging arms. The two hanging arms are respectively rotatably connected to the mobile end of the three-axis robotic arm through rotating shafts, and both ends of the roller are respectively rotatably connected to the side walls between the two hanging arms through rotating shafts.

[0015] Further, the sponge is sleeved outside the roller.

[0016] The beneficial effect of adopting the above further solution is that the mobile end of the three-axis robotic arm drives the wet sponge to displace to the dry crack of the corrugated cardboard. By making the wet sponge contact the dry crack of the corrugated cardboard, the water liquid on the sponge adheres to the cardboard crack, thereby enabling the dry crack of the cardboard to be wetted with water liquid. In addition, the use of a rotatable roller effectively reduces the friction and impact between the sponge and the cardboard, reducing the wear of the cardboard.

[0017] Further, a torsion spring is provided between the hanging arm and the mobile end of the three-axis robotic arm.

[0018] The beneficial effect of adopting the above further solution is that the introduction of the torsion spring endows the hanging arm with a torque elastic force, enabling the roller on the hanging arm to achieve a certain degree of floating. This floating property allows the roller to more softly adapt to the irregularity of the cardboard surface when contacting the cardboard, thereby avoiding overly rigid contact, reducing the risk of damage and crushing of the cardboard, and also enabling the water liquid on the sponge to adhere to the irregular cardboard surface.

[0019] Further, a water-dipping box is provided at the bottom of the gantry, and water liquid is provided inside the water-dipping box.

[0020] Further, the size of the water-dipping box is sufficient for the roller to immerse.

[0021] The beneficial effect of adopting the above further solution is that the robotic arm drives the roller to displace into the water-dipping box, so that the sponge outside the roller gets the water liquid in the water-dipping box and is wetted, ensuring that the sponge remains in a wet state.

[0028] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0029] In the process of producing corrugated cardboard, it is usually necessary to apply glue or perform printing on its surface, and then dry it through a drying device. However, the surface of the dried cardboard is prone to cracking, which will affect the quality of the cardboard. To avoid this situation, it is often necessary to wet the cardboard.

[0030] Traditional wetting methods usually spray water mist on the surface of the corrugated cardboard, but this method has some problems. First, not all positions on the surface of the corrugated cardboard need to be wetted, and excessive wetting will cause insufficient hardness of the cardboard, thus affecting the quality of the cardboard. Therefore, a device that can accurately identify dry cracks and perform local wetting treatment is needed. For this, the inventor has proposed a precise wetting device for corrugated cardboard to solve the above problems.

[0031] The present utility model provides the following preferred embodiments

[0032] As Figures 1-4 shown, a precise wetting device for corrugated cardboard includes:

[0033] A conveyor mechanism 100 for conveying corrugated cardboard;

[0034] A gantry 200 disposed directly above the conveyor mechanism 100;

[0035] The CCD vision detection component 300 is arranged at the bottom of the gantry 200 and faces the conveying mechanism 100. Among them, the CCD vision detection component 300 is used to detect and identify the dry cracks on the corrugated board;

[0036] The three-axis robotic arm 400 is arranged at the top of the gantry 200 and is electrically connected to the CCD vision detection component 300;

[0037] The wetting component 500 is arranged on the mobile end of the three-axis robotic arm 400. When the CCD vision detection component 300 identifies a dry crack, the three-axis robotic arm 400 drives the wetting component 500 to move to the dry crack area on the corrugated board for wetting treatment.

[0038] This device introduces CCD vision detection to achieve real-time detection and identification of dry cracks on the surface of corrugated board. When the dry cracks on the board are identified, the three-axis robotic arm 400 drives the wetting component 500 to accurately position the wetting operation at the dry crack area of the board, rather than the entire surface of the board. This can not only avoid operating on the areas that do not require wetting treatment but also avoid excessive wetting, thus protecting the quality of the board. Through precise wetting treatment, the generation of cracks is effectively prevented, the scrap rate in the production process is reduced, and the production efficiency is improved.

[0039] In this embodiment, as Figures 1-4 shown, the wetting component 500 includes a roller 501, a wet sponge 502, and two hanging arms 503. The two hanging arms 503 are respectively rotatably connected to the mobile end of the three-axis robotic arm 400 through rotating shafts. The two ends of the roller 501 are respectively rotatably connected to the side walls between the two hanging arms 503. The sponge 502 is sleeved outside the roller 501. The mobile end of the three-axis robotic arm 400 drives the wet sponge 502 to move to the dry crack of the corrugated board. By making the wet sponge 502 contact the dry crack of the corrugated board, the water on the sponge 502 adheres to the crack of the board, thereby wetting the dry crack of the board with water. In addition, the use of the rotatable roller 501 effectively reduces the friction and impact between the sponge 502 and the board, reducing the wear of the board.

[0040] In this embodiment, as Figures 1-4As shown, a torsion spring is provided between the hanging arm 503 and the mobile end of the three-axis robotic arm 400. The introduction of the torsion spring endows the hanging arm 503 with a torque elastic force, enabling the roller 501 on the hanging arm 503 to achieve a certain degree of floating. This floating property allows the roller 501 to more softly adapt to the irregularities of the cardboard surface when contacting the cardboard, thereby avoiding overly rigid contact, reducing the risk of damage and crushing to the cardboard, and also enabling the water liquid on the sponge 502 to adhere to the irregular cardboard surface.

[0041] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a water-dipping box 600 is provided at the bottom of the gantry 200, and the interior of the water-dipping box 600 contains water liquid. The size of the water-dipping box 600 is sufficient for the roller 501 to immerse. The robotic arm drives the roller 501 to move into the water-dipping box 600, so that the sponge 502 on the outer side of the roller 501 gets the water liquid in the water-dipping box 600 and is wetted accordingly, ensuring that the sponge 502 remains in a wet state.

[0042] The specific working process of the present utility model is as follows:

[0043] (1) Identify the cracks on the cardboard

[0044] First, the ccd lens of the ccd vision detection component 300 is used to obtain the real-time pixel information of the corrugated cardboard on the conveying mechanism, and the obtained real-time pixel information of the corrugated cardboard is compared with the standard pixel information (the standard pixel information is the shape of the corrugated cardboard in a cracked state).

[0045] (2) Conduct wetting

[0046] When the similarity comparison of the two pixel information is successful, the ccd vision detection component 300 obtains the coordinate axis information of the dry crack of the corrugated cardboard, and transmits the coordinate axis information such as: the x-axis coordinate information and the y-axis coordinate information to the main control. The main control controls the conveying mechanism to stop running, and conveys the coordinate axis information of the dry crack to the three-axis robotic arm 400. The three-axis robotic arm 400 drives the roller 501 to move to the position of this coordinate axis according to the coordinate axis information of the dry crack, and then approaches along the cardboard direction, so that the sponge 502 outside the roller 501 contacts the dry crack on the cardboard, thereby realizing the wetting treatment of the dry crack position of the cardboard alone.

[0047] The above description is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
