Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a sensor-based ink curing detection device and a detection method thereof. Background Art

[0002] When printing paper, trademarks and other printed materials, the inks used usually include UV inks and traditional inks. UV inks rely on ultraviolet light to activate initiators during curing, generating active free radicals or cations, which trigger chain polymerization reactions between prepolymers and monomers, instantly forming a three-dimensional cross-linked solid film layer. Traditional inks mainly cure by drying and volatilization.

[0003] To ensure effective ink curing, it is necessary to test the conditions required for ink curing to ensure stable ink curing during printing. With the rapid development of the printing and packaging industries, ink curing testing technology plays an increasingly important role in quality control and improving production efficiency. Traditional ink curing testing methods typically rely on manual observation or simple physical tests such as tactile inspection or microscopic observation. However, these methods have many limitations, including high subjectivity, low efficiency, and the inability to monitor in real time.

The pendulum rod drives the detection box to swing back and forth so that the adhesive layer contacts the sample to be tested, and the curing degree of the ink is detected by the change in resistance of the resistance strain gauge.

[0007] In the above-mentioned sensor-based ink curing detection device, the swing assembly also includes motor 2, which is fixed to the driving end of motor 1, and the ends of rocker arm 1 and rocker arm 2 are fixed to the driving end of motor 2.

[0008] In the above-mentioned sensor-based ink curing detection device, the outer wall of the cleaning tank is provided with a groove consistent with the specifications of the detection box, and a sealing assembly is provided at the end of the cleaning tank, and the sealing assembly includes a right-angle plate fixed to the outer wall of the end of the cleaning tank, an electric push rod is fixed to the right-angle plate, and the driving end of the electric push rod is fixed with a sealing plate slidably inserted in the end of the cleaning tank, and the outer wall of the support rod is fixed with a liquid storage tank through a connecting rod, and a liquid pump is provided in the liquid storage tank, and the output end of the liquid pump is connected to an infusion pipe, the middle part of the infusion pipe is wrapped around the outer wall of the motor 2, and the end of the infusion pipe is fixed to the top of the cleaning tank and connected to its interior, and a return liquid pipe is connected between the sealing plate and the end of the liquid storage tank.

[0009] The top end of the support frame is provided with a protruding portion, and the bottom end of the support frame is fixed with a protruding portion.

[0010] In the above-mentioned sensor-based ink curing detection device, a conveyor belt for conveying samples to be tested is provided on the detection table.

[0011] In the above-mentioned sensor-based ink curing detection equipment, a clamping mechanism for clamping the sample to be tested is provided on the detection table, and the clamping mechanism includes two U-shaped plates symmetrically and slidably inserted on the detection table, and the ends of the U-shaped plates are fixedly connected to the clamping plates located on the upper side of the detection table, and a return spring is sleeved on the U-shaped plate, and the two ends of the return spring are respectively fixedly connected to the lower side wall of the detection table and the outer wall of the U-shaped plate. A motor is fixed to the lower side wall of the detection table, and the driving end of the motor is fixedly connected to a turntable. The other end of the U-shaped plate is located on the lower side of the turntable and in contact with it, and an inclined surface is provided at the contact between the turntable and the U-shaped plate.

[0012] A detection method for an ink curing detection device based on a sensor, comprising the following steps: S1, the sample to be tested is placed on the conveyor belt, and the rotation of the conveyor belt drives the sample to be tested forward; S2: When the frontmost sample to be tested moves to the middle of the test table, the second pendulum is in a vertical position, and the light beam emitter is activated to emit a light beam to contact the sample to be tested. When the ink is completely cured, the light beam will be emitted and received by the photoelectric sensor. When the ink is not cured, the ink will absorb the light, reducing the reflection of the light beam. The degree of ink curing is determined by optical signal analysis; S3: Motor 1 is started to drive Motor 2 to rotate, causing the test box to be rotated out of the cleaning tank. When the pendulum arm 1 rotates to a vertical position, Motor 1 stops and Motor 2 is started to drive the pendulum arm 1 to swing back and forth. During the swinging process, the adhesive layer continuously contacts the sample to be tested. If the ink is not solidified, the adhesive layer will adhere to the ink, pulling the diaphragm and the resistance strain gauge to deform. The degree of strain reflected by the voltage and current is measured to determine the degree of ink solidification. S4, after the test is completed, the motor 1 drives the motor 2 to rotate, so that the test box is transferred to the cleaning tank for cleaning, and the next sample to be tested is tested.

[0013] Compared with existing technologies, the advantages of this sensor-based ink curing detection device are: 1. The light beam emitted by the light emitter contacts the sample to be tested, and the reflected light beam signal is detected by the photoelectric sensor to determine the curing degree of the ink. The pendulum drives the detection box to swing back and forth to make the adhesive layer contact the sample to be tested, and the curing degree of the ink is detected by the change in the resistance of the resistance strain gauge. The dual detection and analysis of the ink curing degree make the test results more accurate. 2. The liquid pump pumps the ink cleaning liquid in the liquid storage tank into the liquid infusion tube, and enters the upper end of the cleaning tank from the end of the liquid infusion tube. The ink cleaning liquid flows along the inside of the cleaning tank and contacts the sticky hair layer, washing away the ink adhering to the sticky hair layer. The flow of the ink cleaning liquid in the liquid infusion tube can also absorb the heat of the two surfaces of the motor, increasing the temperature of the ink cleaning liquid. The heated ink cleaning liquid can more easily clean the ink; 3. When the motor 2 drives the swing rod 1 and the swing rod 2 to swing back and forth, the arc plate is driven to swing synchronously through the cross bar. When the arc plate swings until the protrusion contacts the push plate, it pushes the push plate to move downward, moves the telescopic spring, and the knocking plate rotates. When the protrusion rotates away from the push plate, the push plate moves upward under the reverse elastic force of the telescopic spring, pulling the end of the knocking plate to rotate upward, and the other end of the knocking plate rotates downward to knock the resonance plate, and the vibration is transmitted to the filter screen. Under the action of the vibration, the solid impurities on the surface of the filter screen slide downward, preventing the solid impurities from clogging the filter screen and affecting the flow of the ink cleaning liquid; To sum up, the present invention detects the degree of ink curing by combining an optical sensor to detect the reflectivity of the ink and the deformation of the resistance strain gauge driven by the contact between the sticky layer and the ink. The detection effect is more accurate, and the sticky layer is cleaned after a single detection, so that the sticky layer can perform detection work continuously, and absorb the heat from the motor 2 to heat the ink cleaning liquid, thereby improving the cleaning effect of the ink cleaning liquid.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figures 1-10 , a sensor-based ink curing detection device, including a detection table 1 on which a sample 29 to be detected is placed, a conveyor belt 28 for conveying the sample 29 to be detected is provided on the detection table 1, the detection table 1 is connected to a motor 3 through a support plate 2, the driving end of the motor 3 is connected to a swing component, the detection table 1 is also connected to a cleaning tank 5 through a support rod 21, the swing component includes a pendulum 1 6 and a pendulum 2 13, the end of the pendulum 2 13 is provided with a light beam emitter and a photoelectric sensor, the end of the pendulum 1 6 is fixed with a detection box 7, the outer wall of the detection box 7 is provided with a mounting groove 9, the inner wall of the mounting groove 9 is fixed with a diaphragm 11, a resistance strain gauge 10 is fixed between the diaphragm 11 and the inner wall of the mounting groove 9, and a sticky hair layer 8 is evenly distributed on the outer wall of the diaphragm 11, the swing component It also includes motor 2 4, which is fixed on the driving end of motor 1 3, and the ends of pendulum 1 6 and pendulum 2 13 are fixed on the driving end of motor 2 4. The setting of diaphragm 11 prevents the cleaning liquid from entering the installation groove 9 when cleaning the sticky layer 8. When the detection box 7 is located in the cleaning groove 5, pendulum 2 13 is set vertically, and the conveyor belt 28 drives the sample to be tested 29 to move to the lower side of pendulum 2 13. The reflectivity of the sample to be tested 29 is detected by the light beam emitter and the photoelectric sensor. Uncured ink will absorb more light, while cured ink will reflect more light. The light beam emitter emits light to contact the ink, and the photoelectric sensor detects the intensity of the reflected light. The curing degree of the ink is determined by detecting the intensity of the reflected light through the photoelectric sensor.

[0018] To further illustrate, the resistance strain gauge 10 implements signal conversion through a Wheatstone bridge circuit, and performs signal amplification, filtering, and compensation through an amplifier circuit to remove noise and interference, and finally converts the electrical signal into a digital signal through analog-to-digital conversion for display; The test platform 1 is provided with a clamping mechanism for clamping the sample 29 to be tested. The clamping mechanism includes two U-shaped plates 30 symmetrically and slidably inserted on the test platform 1. The ends of the U-shaped plates 30 are fixedly connected to the clamping plates 31 located on the upper side of the test platform 1. A return spring 20 is sleeved on the U-shaped plate 30. The two ends of the return spring 20 are respectively fixedly connected to the lower side wall of the test platform 1 and the outer wall of the U-shaped plate 30. A motor 32 is fixed to the lower side wall of the test platform 1. The driving end of the motor 32 is fixedly connected to the turntable 33. The other end of the U-shaped plate 30 is located at the lower side of the turntable 30 and contacts it. An inclined surface 34 is provided at the contact point between the disk 33 and the U-shaped plate 30. After the sample 29 to be tested moves to the position directly below the second rocker 13, the rotation of the conveyor belt 28 is stopped, and the motor 32 is started to drive the turntable 33 to rotate. During the rotation of the turntable 33, the inclined surface 34 in contact with the U-shaped plate 30 rotates from a thin part to a thick part, thereby squeezing the U-shaped plate 30 downward, so that the clamping plate 31 contacts and presses the end of the sample 29 to be tested, thus completing the fixation of the sample 29 to be tested. This ensures that the subsequent contact between the adhesive layer 8 and the sample 29 will not cause the sample 29 to be tested to move, so that the testing work can proceed normally. After the optical inspection is completed, motor 1 (3) is started to drive motor 2 (4) to rotate. The inspection box 7 is rotated out of the cleaning tank 5 and positioned above the sample 29 to be inspected. The adhesive layer 8 contacts the sample 29 to be inspected. Motor 2 (4) is started to drive the swing arm 1 (6) and the inspection box 7 to swing back and forth. The adhesive layer 8 is in constant contact with the ink. When the ink is not solidified, the adhesive layer 8 will adhere to the ink, pulling the diaphragm 11 and the resistance strain gauge 10 to deform. To further illustrate, the adhesive layer 8 is arranged in a multi-segment spiral. The multi-segment spiral arrangement has a larger contact surface when in contact with the ink, and the corresponding adhesion force will also be amplified accordingly. Therefore, when the ink is not solidified, the adhesive layer 8 moves outward under the adhesion of the ink, causing the diaphragm 11 and the resistance strain gauge 10 to move outward, and the resistance value of the resistance strain gauge 10 changes. The resistance strain gauge 10 alone cannot generate current directly, and signal conversion must be achieved through a Wheatstone bridge circuit.

[0019] The curing degree of the ink is determined by emitting a light beam through a light beam emitter to contact the sample to be tested 29, and detecting the reflected light beam signal through a photoelectric sensor. The pendulum 6 drives the detection box 7 to swing back and forth so that the adhesive layer 8 contacts the sample to be tested 29, and the curing degree of the ink is detected by the change in the resistance of the resistance strain gauge 10. The double detection is combined with the analysis of the curing degree of the ink, and the detection result is more accurate.

[0020] The outer wall of the cleaning tank 5 is provided with a slot that is consistent with the specifications of the detection box 7. The end of the cleaning tank 5 is provided with a sealing assembly, which includes a right-angle plate fixed to the outer wall of the end of the cleaning tank 5, and an electric push rod 12 is fixed to the right-angle plate. The driving end of the electric push rod 12 is fixed with a sealing plate 14 that is slidably inserted at the end of the cleaning tank 5. The outer wall of the support rod 21 is fixed with a liquid storage tank 15 through a connecting rod. A liquid pump is provided in the liquid storage tank 15, and the output end of the liquid pump is connected to an infusion tube 16. The middle part of the infusion tube 16 is wound around the outer wall of the motor 2 4, and the end of the infusion tube 16 is fixed to the top of the cleaning tank 5 and is connected to its interior. A return liquid pipe 17 is connected between the sealing plate 14 and the end of the liquid storage tank 15. After the detection of a single sample 29 to be tested is completed, the driving end of the motor 3 rotates The dynamic detection box 7 is inserted into the cleaning tank 5, and the driving end of the electric push rod 12 is extended to make the sealing plate 14 contact with the outer wall of the end of the detection box 7 to seal the end of the cleaning tank 5. The liquid pump is started to pump the ink cleaning liquid used for cleaning the ink in the liquid storage tank 15 into the liquid infusion pipe 16, and enters the upper end of the cleaning tank 5 from the end of the liquid infusion pipe 16. The ink cleaning liquid flows along the inside of the cleaning tank 5 and contacts the sticky hair layer 8, washing away the ink adhered to the sticky hair layer 8. The flow of the ink cleaning liquid in the liquid infusion pipe 16 can also absorb the heat from the surface of the motor 2 4, so that the temperature of the ink cleaning liquid increases. The heated ink cleaning liquid can more easily clean the ink, and then the ink cleaning liquid is discharged back to the liquid storage tank 15 from the return pipe 17, realizing the reuse of the ink cleaning liquid. Furthermore, the sealing plate 14 may be a rubber plate.

[0021] The liquid storage tank 15 is provided with a slot, in which a filter is fixed, and a resonance plate 18 is fixed to the outer wall of the filter. A knocking mechanism is connected between the rocker arm 213, the support plate 2 and the resonance plate 18. The knocking mechanism includes a cross bar fixed to the outer wall of the rocker arm 213, and an arc plate 19 is fixed at the end of the cross bar. The outer wall of the arc plate 19 is provided with a protrusion 22. The outer wall of the support plate 2 is fixedly connected with a cross plate 26, and the end of the cross plate 26 is rotatably connected with a knocking plate 27. One end of the knocking plate 27 is located on the upper side of the resonance plate 18. A slide groove is provided on the support plate 2, and a push plate 23 is slidingly provided in the slide groove. A guide rod 25 is fixed to the lower side wall of the push plate 23, and the end of the guide rod 25 is slidably inserted in the inner bottom wall of the slide groove. A telescopic spring 24 is fixedly connected between the push plate 23 and the inner bottom wall of the slide groove. The arc plate 19 contacts the upper side wall of the push plate 23, and the other end of the knocking plate 27 One end is located at the lower side of the push plate 23 and is fixedly connected to the push plate 23 with a pull rope, and a filter is set to filter the flowing ink cleaning liquid to remove solid impurities in the ink cleaning liquid. In the process of motor 24 driving the rocker arm 1 6 and the rocker arm 2 13 to swing back and forth, the arc plate 19 is driven to swing synchronously by the cross bar. When the arc plate 19 swings to the point where the protrusion 22 contacts the push plate 23, the push plate 23 is pushed to move downward, the telescopic spring 24 is moved, and the knocking plate 27 is rotated. When the protrusion 22 rotates away from the push plate 23, the push plate 23 moves upward under the reverse elastic force of the telescopic spring 24, pulling the end of the knocking plate 27 to rotate upward, and the other end of the knocking plate 27 rotates downward to knock the resonance plate 18, and the vibration is transmitted to the filter screen. Under the action of the vibration, the solid impurities on the surface of the filter screen slide downward, thereby preventing the solid impurities from clogging the filter screen and affecting the flow of the ink cleaning liquid.

[0022] A detection method for an ink curing detection device based on a sensor, comprising the following steps: S1, the sample 29 to be tested is placed on the conveyor belt 28, and the rotation of the conveyor belt 28 drives the sample 29 to be tested to move forward; S2: When the frontmost sample 29 moves to the middle of the test platform 1, the second pendulum 13 is in a vertical position, and the light beam emitter is activated to emit a light beam that contacts the sample 29. When the ink is completely cured, the light beam is emitted and received by the photoelectric sensor. When the ink is not cured, the ink absorbs the light, reducing the reflection of the light beam. The degree of ink curing is determined by analyzing the light signal. S3: Motor 1 (3) is started to drive Motor 2 (4) to rotate, causing the test box 7 to be rotated out of the cleaning tank 5. When the swing arm 6 rotates to a vertical position, Motor 1 (3) is stopped, and Motor 2 (4) is started to drive the swing arm 6 to swing back and forth. During the swinging process, the adhesive layer 8 is constantly in contact with the sample 29 to be tested. When the ink is not solidified, the adhesive layer 8 will adhere to the ink, pulling the diaphragm 11 and the resistance strain gauge 10 to deform. The degree of ink solidification is determined by measuring the voltage and current to reflect the strain. S4, after the test is completed, the motor 1 3 drives the motor 2 4 to rotate, so that the test box 7 is transferred into the cleaning tank 5 for cleaning, and the next test sample 29 is tested.
