Description

Technical Field

[0001] This application relates to the technical field of white cardboard detection, and in particular, to a paper sample aging test device and method applicable to white cardboard. Background Art

[0002] White cardboard is a kind of paper that is firm, thick, and has a relatively large basis weight. Its main uses include printing business cards, certificates, invitations, covers, monthly calendars, and postal postcards, etc. The aging detection of white cardboard is a key step in testing the quality of white cardboard, and the aging detection data of white cardboard is one of the important indicators for deriving the durability of white cardboard.

[0003] The aging of white cardboard is mainly affected by environmental factors, including factors such as light, high temperature, high humidity, acid and alkali, etc., and its aging process is affected by multiple factors. First of all, the main components of white cardboard include cellulose, hemicellulose, and lignin. These components will undergo chemical changes under specific environments, resulting in paper aging. Specifically, cellulose is prone to hydrolysis and oxidation under the catalysis of acid and alkali, and the oxidation of hemicellulose and lignin will also cause the paper to turn yellow and brittle. In addition, ultraviolet light can break the chemical bonds in lignin, further accelerating the embrittlement process of the paper.

[0004] The existing aging detection method for white cardboard is to accelerate the aging rate of white cardboard through an aging test chamber and compare the diffuse reflection changes before and after. However, since the surface of white cardboard is very easy to be scratched, it will affect the detection result during the aging test, resulting in inaccurate inspection effect. Summary of the Invention

[0005] In order to overcome the above-mentioned technical problems in the prior art, this application provides a paper sample aging test device and method applicable to white cardboard.

[0006] In the first aspect, a paper sample aging test device applicable to white cardboard provided by this application adopts the following technical solutions: A paper sample aging test device applicable to white cardboard includes A test bench, at one end of which there is a visual detection mechanism for detecting the scratch condition on the surface of the paper sample, and at the other end there is an aging test chamber; A cutting and transfer mechanism is movably arranged on the test bench. The cutting and transfer mechanism includes a cutting component for cutting the paper sample and a transfer component for driving the cutting component to adjust its position. The transfer component is electrically connected to the visual detection mechanism. The transfer component can drive the cutting component to cut the non-scratched part of the paper sample according to the detection situation of the visual detection mechanism, and transfer the cut part of the paper sample into the aging test chamber for aging test.

[0007] Further, a carrying frame for carrying the paper sample is provided at the visual inspection mechanism on the test bench. The cutting assembly includes a cutting plate located below the carrying frame, an annular cutter located above the carrying frame, a lifting member for driving the annular cutter to move up and down towards the cutting plate, and a suction member for sucking the paper sample inside the annular cutter. One side of the cutting plate is fixed with a connecting frame. The annular cutter is connected to the connecting frame through the lifting member in a lifting and sliding manner. The suction member is located on the connecting frame, and the connecting frame is connected to the output end of the transfer assembly.

[0008] Further, the suction member includes a suction cylinder with a closed top end and a suction pump arranged on the connecting frame. The suction pump is connected to the side wall of the suction cylinder through a pipeline. The annular cutter is sleeved on the bottom end of the suction cylinder in a sliding manner. A spring is connected between the annular cutter and the suction cylinder. The telescopic direction of the spring is the same as the sliding direction of the annular cutter. The output end of the lifting member is fixedly connected to the suction cylinder. The lifting member drives the suction cylinder and the annular cutter to move towards the cutting plate until the bottom end of the suction cylinder contacts and sucks the paper sample. At this time, the annular cutter presses tightly against the cutting plate to realize the cutting of the paper sample, and at the same time, the spring is compressed.

[0009] Further, both the suction cylinder and the cutting plate are made of transparent acrylic plates.

[0010] Further, a partition is arranged above the pipeline inside the suction cylinder. A transparent hemispherical elastic capsule is installed above the partition. A water injection port for injecting water into the transparent hemispherical elastic capsule is arranged on the side wall of the suction cylinder.

[0011] Further, the visual inspection mechanism includes two groups of visual sensors and a data processor electrically connected to the visual sensors. The two groups of visual sensors are respectively located on the upper and lower sides of the carrying frame. The transfer assembly is electrically connected to the data processor.

[0012] Further, the transfer assembly includes a first displacement member arranged on the test bench and a second displacement member arranged on the output end of the first displacement member. The connecting frame is fixedly connected to the second displacement member. The first displacement member drives the second displacement member to reciprocate along the length direction of the test bench, and the second displacement member drives the connecting frame to reciprocate along the width direction of the test bench.

[0013] In a second aspect, a paper sample aging test method applicable to white cardboard provided by the present application, based on the above-mentioned paper sample aging test device applicable to white cardboard, includes the following steps. S1, paper sample surface detection. Place the paper sample in the carrying frame and start the visual inspection mechanism. The visual inspection mechanism detects the scratch condition on the surface of the paper sample and transmits the detection result to the transfer assembly. S2. Pattern cutting. According to the detection results of the vision detection mechanism, the transfer component drives the cutting component to move to the appropriate cutting part of the pattern through the connecting frame. At this time, the annular cutter and the cutting plate are respectively located on the upper and lower sides of the part to be cut. Then, the lifting member is started, and the lifting member drives the suction cylinder and the annular cutter to move towards the cutting plate until the bottom of the suction cylinder contacts the pattern. At this time, the annular cutter is elastically pressed against the cutting plate to complete the cutting of the pattern. S3. Pattern aging test. After the pattern cutting is completed, the suction pump is started. The suction pump stably adsorbs the cut part of the pattern on the bottom of the suction cylinder through negative pressure adsorption. Then, the lifting member is started, and the suction cylinder takes the cut pattern away from the carrying frame. Finally, the transfer component transfers the cut pattern part to the aging test chamber through the cutting component for aging test.

[0014] In summary, the beneficial technical effects of the present application are as follows: After the vision detection mechanism detects the scratch condition on the surface of the pattern, the cutting component can cut an appropriate part of the pattern, and under the drive of the transfer component, it is transferred to the aging test chamber for aging test, reducing the influence on the test results caused by excessive scratches on the surface of the pattern.

Detailed Embodiments

[0019] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.

[0020] The embodiments of the present application disclose a paper sample aging test device and method applicable to white cardboard.

[0021] Referring to Figure 1 , a paper sample aging test device applicable to white cardboard includes a test bench 1, a visual detection mechanism, a cutting and transfer mechanism, and an aging test chamber 2 arranged on the test bench 1. The visual detection mechanism and the aging test chamber 2 are respectively located at both ends of the test bench 1, and the cutting and transfer mechanism is movably arranged between the visual detection mechanism and the aging test chamber 2. When conducting an aging test on white cardboard, the visual detection mechanism can first detect the scratch condition on the surface of the paper sample. The part of the paper sample surface without scratches or with fewer scratches is the suitable part for the aging test. Then, according to the detection situation, the cutting and transfer mechanism is driven to cut the suitable part of the paper sample, and the cutting and transfer mechanism transfers the cut part of the paper sample into the aging test chamber 2 for the aging test.

[0022] To reduce the influence of scratches on both sides of the paper sample on the test results, referring to Figure 1 and Figure 2 , a bearing frame 5 for carrying the paper sample is horizontally arranged on the test bench 1, and the middle part of the bearing frame 5 is hollow. The visual detection mechanism includes two groups of visual sensors 81 and a data processor 82 electrically connected to the visual sensors 81. The two groups of visual sensors 81 are respectively located on the upper and lower sides of the bearing frame 5 and are directly opposite the hollow part of the bearing frame 5, so that under the combined action of the two groups of visual sensors 81, the scratch conditions on both the upper and lower surfaces of the paper can be effectively detected. The two groups of visual sensors 81 transmit the detected data to the data processor 82, and the data processor 82 processes the signal data to determine the position of the suitable part to be cut on the paper sample; the data processor 82 is electrically connected to the cutting and transfer mechanism, so that the data processor 82 can drive the cutting and transfer mechanism to quickly move to the suitable part of the paper sample to be cut, thereby realizing the precise cutting of the paper sample.

[0023] To achieve the rapid cutting of the paper sample, referring to Figure 1 and Figure 2 , the cutting and transfer mechanism includes a cutting component 3 for cutting the paper sample and a transfer component 4 for driving the position adjustment of the cutting component 3. The transfer component 4 is electrically connected to the data processor 82, and the data processor 82 can drive the transfer component 4 to drive the cutting component 3 to quickly move to the suitable part of the paper sample to be cut, so that the cutting component 3 can perform precise cutting on the paper sample. Subsequently, the transfer component 4 transfers the cut part of the paper sample through the cutting component 3 into the aging test chamber 2 for the aging test.

[0024] To achieve lightweight design, in the embodiments of the present application, the cutting component 3 has the functions of cutting and grasping the paper sample. For the setting of the cutting component 3, referring toFigure 1 , Figure 2 and Figure 3 , the cutting assembly 3 includes a cutting plate 31 located below the carrying frame 5, a circular cutter 32 located above the carrying frame 5, a lifting member 33 for driving the circular cutter 32 to move up and down towards the cutting plate 31, and a suction member for sucking the paper pattern inside the circular cutter 32; a connecting frame 6 is connected to the output end of the transfer assembly 4, the connecting frame 6 is arranged in an inverted T-shaped structure, one side of the horizontal end of the connecting frame 6 is fixedly connected to the output end of the transfer assembly 4, and the lifting member 33 is installed on the vertical end of the connecting frame 6; the lifting member 33 can be a linear driving structure such as an electric push rod, a cylinder, a screw-nut pair, etc. In the embodiment of the present application, the lifting member 33 is arranged as a small cylinder, the cylinder body of the cylinder is fixed on the vertical end of the connecting frame 6, and the piston rod of the cylinder extends vertically downward. The cutting plate 31 is fixedly installed on the side of the horizontal end of the connecting frame 6 away from the transfer assembly 4, the cutting plate 31 is horizontally arranged below the carrying frame 5, and when the cutting plate 31 moves to the position of the carrying frame 5, the upper surface of the cutting plate 31 fits with the lower surface of the carrying frame 5. A connecting plate 16 is horizontally arranged directly above the cutting plate 31, the connecting plate 16 is fixedly connected to the output end of the lifting member 33, both the suction member and the circular cutter 32 are installed on the lower surface of the connecting plate 16, and are located at one end of the connecting plate 16 away from the lifting member 33.

[0025] Refer to Figure 2 and Figure 3, the adsorbing member includes an adsorption cylinder 34 with a closed top end and an air suction pump 35 arranged on the vertical end of the connecting frame 6. The top of the adsorption cylinder 34 is fixedly installed on the connecting plate 16. An air flow channel 14 is formed on the side wall of the adsorption cylinder 34. The air suction pump 35 is communicated with the air flow channel 14 on the adsorption cylinder 34 through a pipeline 7, so that under the adsorption action of the air suction pump 35, the cut paper sample part can be negatively adsorbed at the bottom end of the adsorption cylinder 34. The annular cutting knife 32 is slidably sleeved at the bottom end of the adsorption cylinder 34. To achieve stable cutting of the paper sample, a spring 9 is connected between the annular cutting knife 32 and the adsorption cylinder 34. The telescopic direction of the spring 9 is consistent with the sliding direction of the annular cutting knife 32. One end of the spring 9 is fixedly connected to the inner wall of the top of the annular cutting knife 32, and the other end is fixedly connected to the outer wall of the bottom of the adsorption cylinder 34. In the non-working state, the spring 9 is in its original length. At this time, the cutting edge at the bottom of the annular cutting knife 32 is located below the bottom end of the adsorption cylinder 34. In the working state, the lifting member 33 drives the adsorption cylinder 34 to move towards the cutting plate 31 through the connecting plate 16 until the bottom end of the adsorption cylinder 34 contacts the paper sample. At this time, the spring 9 is compressed, and the annular cutting knife 32 presses the paper sample against the cutting plate 31 under the drive of the spring 9 to achieve cutting of the paper sample. At the same time, the air suction pump 35 is started, and the air suction pump 35 can stably adsorb the cut paper sample part at the bottom end of the adsorption cylinder 34, so that when the lifting member 33 drives the adsorption cylinder 34 and the annular cutting knife 32 to move away from the cutting plate 31 through the connecting plate 16, the cut paper sample part can be taken away from the carrying frame 5, so that it can continue to be smoothly transferred into the aging test chamber 2 for aging test.

[0026] For the setting of the transfer assembly 4, refer to Figure 1 and Figure 2 , the transfer assembly 4 includes a first displacement member 41 arranged on the test bench 1 and a second displacement member 42 arranged on the output end of the first displacement member 41. The first displacement member 41 and the second displacement member 42 can be linear drive structures such as electric push rods, cylinders, and screw nut pairs. In the embodiment of the present application, both the first displacement member 41 and the second displacement member 42 are set as screw nut pairs. The connecting frame 6 is fixedly connected to the output end of the second displacement member 42. The second displacement member 42 is installed on the output end of the first displacement member 41. The first displacement member 41 drives the second displacement member 42 to reciprocally slide along the length direction of the test bench 1, and the second displacement member 42 drives the connecting frame 6 to reciprocally slide along the width direction of the test bench 1, so that under the combined action of the first displacement member 41 and the second displacement member 42, the cutting assembly 3 can quickly position and cut each part of the paper sample located in the carrying frame 5.

[0027] To enable the cutting assembly 3 to smoothly transfer the paper sample into the aging test chamber 2 for aging test, refer to Figure 1, one side of the aging test chamber 2 close to the carrying frame 5 is the entrance of the chamber. A chute 17 is penetrated and opened on the side wall of the aging test chamber 2. The length direction of the chute 17 is consistent with the length direction of the test bench 1, and the width of the chute 17 is not less than the maximum dimension between the connecting plate 16 and the cutting plate 31. When the transfer assembly 4 drives the cutting assembly 3 to drive the paper sample to move into the aging test chamber 2, both the cutting plate 31 and the connecting plate 16 pass through the chute 17 and are located inside the aging test chamber 2, while the lifting member 33, the second displacement member 42, etc. are all located outside the aging test chamber 2, avoiding damage to the lifting member 33 and the second displacement member 42 during the aging test.

[0028] The aging test chamber 2 simulates the aging speed of the paper sample under different light conditions by adjusting the light intensity. To ensure that the light can reach the paper in the adsorption cylinder 34 smoothly, both the adsorption cylinder 34 and the cutting plate 31 are made of transparent acrylic plates, so that the adsorption cylinder 34 can stably hold the paper for the aging test.

[0029] Considering that the light intensity adjustment of the aging test chamber 2 is mostly in a stepped manner, and the light intensity difference between adjacent two steps is relatively large. To simulate the stepless adjustment of the light intensity on the paper as much as possible, referring to Figure 3 , a transparent partition 10 is arranged above the pipeline 7 in the adsorption cylinder 34, a transparent hemispherical elastic capsule 11 is installed above the partition 10, and a water injection port 12 for injecting water into the transparent hemispherical elastic capsule 11 is arranged on the side wall of the adsorption cylinder 34. A water pump 15 is installed on the connecting frame 6, and the water pump 15 is communicated with the water injection port 12 through a water pipe 13. When fine adjustment of the light is required, a certain amount of water can be injected into the transparent hemispherical elastic capsule 11 through the water pump 15, so that the transparent hemispherical elastic capsule 11 gradually expands under the filling of water, thus forming an approximate convex lens structure. According to the principle of light concentration by a convex lens, the light in the aging test chamber 2 can be converged. As the transparent hemispherical elastic capsule 11 increases / decreases, its focal length changes, resulting in a change in the light intensity at the center of the paper sample at the bottom of the adsorption cylinder 34, so as to achieve the simulation of the stepless adjustment of the light intensity at the center of the paper.

[0030] A paper sample aging test method applicable to white cardboard provided by the present application adopts the following technical solutions: S1, paper sample surface detection. Place the paper sample in the carrying frame 5 and start the visual detection mechanism. The visual detection mechanism detects the scratch condition on the surface of the paper sample and transmits the detection result to the transfer assembly 4; S2. Pattern cutting. According to the detection of the vision detection mechanism, the transfer assembly 4 drives the cutting assembly 3 to move to the appropriate part of the pattern to be cut through the connecting frame 6. At this time, the annular cutter 32 and the cutting plate 31 are respectively located on the upper and lower sides of the part to be cut. Then, the lifting member 33 is started, and the lifting member 33 drives the suction cylinder 34 and the annular cutter 32 to move towards the cutting plate 31 until the bottom of the suction cylinder 34 contacts the pattern. At this time, the annular cutter 32 elastically abuts against the cutting plate 31 to realize the cutting of the pattern. S3. Pattern aging test. After the pattern cutting is completed, the suction pump 35 is started. The suction pump 35 stably adsorbs the cut part of the pattern on the bottom of the suction cylinder 34 through negative pressure adsorption. Then, the lifting member 33 is started, and the suction cylinder 34 takes the cut pattern away from the bearing frame 5. Finally, the transfer assembly 4 transfers the cut pattern part to the aging test box 2 through the cutting assembly 3 for aging test.

[0031] The implementation principle of a pattern aging test device and method for white cardboard according to an embodiment of the present application is as follows: First, place the pattern in the bearing frame 5 and start the vision detection mechanism. The vision detection mechanism detects the scratch condition on the surface of the pattern and transmits the detection result to the transfer assembly 4. According to the detection of the vision detection mechanism, the transfer assembly 4 drives the cutting assembly 3 to move to the appropriate part of the pattern to be cut through the connecting frame 6. At this time, the annular cutter 32 and the cutting plate 31 are respectively located on the upper and lower sides of the part to be cut. Then, the lifting member 33 is started, and the lifting member 33 drives the suction cylinder 34 and the annular cutter 32 to move towards the cutting plate 31 until the bottom of the suction cylinder 34 contacts the pattern. At this time, the annular cutter 32 elastically abuts against the cutting plate 31 to realize the cutting of the pattern. After the pattern cutting is completed, the suction pump 35 is started. The suction pump 35 stably adsorbs the cut part of the pattern on the bottom of the suction cylinder 34 through negative pressure adsorption. Then, the lifting member 33 is started, and the suction cylinder 34 takes the cut pattern away from the bearing frame 5. Finally, the transfer assembly 4 transfers the cut pattern part to the aging test box 2 through the cutting assembly 3 for aging test.

[0032] When carrying out the aging test, an appropriate amount of water can be injected into the transparent hemispherical elastic capsule 11 through the water pump 15, so that the transparent hemispherical elastic capsule 11 expands, thereby changing the light intensity reaching the center of the pattern on the bottom end of the suction cylinder 34, so as to achieve the stepless adjustment of the light intensity of the center of the paper.

[0033] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
