Description

Technical Field

[0001] The invention belongs to the technical field of viscosity testing, and in particular relates to an adhesive viscosity testing device. Background Art

[0002] After the production of adhesives, the viscosity quality of the adhesives needs to be tested. Through the viscosity test of the adhesives, we can understand whether the adhesives meet the expected bonding performance standards and ensure that the products using the adhesives have reliable connections and stability. The test results can provide a basis for research and development and improvement, help find more suitable formulas or adjust the production process to improve the viscosity of the adhesives.

[0003] Before testing the viscosity of the adhesive, it is necessary to apply the adhesive to the two test substrates. After application, it is necessary to add extrusion force between the two test substrates to assist the adhesive to better contact and infiltrate the substrates, promote the interaction between molecules, and thus ensure the bonding effect. The extrusion force currently applied is fixed. For adhesives with high viscosity, there will be greater resistance during bonding. Therefore, sufficient extrusion force is required to overcome this resistance and ensure that the adhesive can be evenly distributed between the two test substrates and fit tightly. For adhesives with low viscosity, their own resistance is relatively small, and a larger extrusion force is easy to cause This causes excessive overflow of adhesive, which is not conducive to stable bonding. The current test results only determine whether the adhesive strength of the tested adhesive meets the standard, but there is no direct calculation of the difference between the tested adhesive strength value and the design threshold. As a result, the feedback test data is not comprehensive and accurate, making it difficult to accurately evaluate the stability and consistency of adhesive performance, and it is impossible to clearly know the viscosity changes in different batches or under different conditions, which is not conducive to effective control of product quality. The lack of difference value comparison will make the optimization direction of adhesive performance unclear, making it difficult to make targeted adjustments and improvements, affecting the R&D efficiency and effect of adhesives.

A larger pressure is used for adhesives with high viscosity to ensure that the adhesive can be evenly distributed between the two test substrates and fit tightly. A smaller pressure is used for adhesives with low viscosity to avoid the problem that a large extrusion pressure may easily cause excessive overflow of the adhesive, which is not conducive to stable bonding.

[0015] By setting the estimated initial viscosity strength setting mechanism, glue coating mechanism, fixed substrate and pulling substrate, the automatic coating operation of adhesive can be performed between the fixed substrate and the pulling substrate, and the glue coating thickness can be automatically adjusted based on the estimated viscosity strength value of the adhesive, so that the stronger the viscosity of the adhesive, the thicker the coating thickness of the adhesive, which meets the actual situation that the use of adhesives with high viscosity requires stronger adhesion and the thickness used is thicker, while the use of adhesives with low viscosity also requires less adhesion and the thickness used is relatively thinner.

[0017] By setting up the test result difference feedback mechanism, viscosity strength feedback mechanism and initial viscosity strength estimation setting mechanism, the viscosity strength value of the adhesive can be directly fed back and displayed, and the difference with the estimated viscosity strength value of the adhesive can be calculated and fed back, so that the feedback test data is more comprehensive and accurate, and the optimization direction of the adhesive performance is clearer, which enables the staff to make better targeted adjustments to the improvement of the adhesive, thereby improving the research and development efficiency and improvement effect of the adhesive.

[0036] An alarm device 13 and a PLC controller 14 are also fixedly installed on the upper end of the base 1. The PLC controller 14 is electrically connected to the viscosity strength feedback mechanism 2, the initial viscosity strength estimation setting mechanism 3, the pulling compensation mechanism 4, the pressurization auxiliary mechanism 5, the dust removal and cleaning mechanism 6, the glue coating mechanism 7 and the test result difference feedback mechanism 8 respectively.

[0037] The operating principle of the present invention is described as follows: before the test, the PLC controller 14 controls the electric telescopic rod 62 to drive the intermediate tube 63 to move, so that the intermediate tube 63 extends between the fixed substrate 9 and the pulling substrate 12, and the PLC controller 14 controls the rotation motor assembly 65 and the suction pump 67 to operate, and the rotation motor assembly 65 drives the support shaft 61 to rotate, thereby causing the intermediate tube 63 and the suction head 64 to rotate between the fixed substrate 9 and the pulling substrate 12. After the support shaft 61 rotates one circle, it returns to its original position and rotates, and the suction pump 67 cooperates with the suction head 67 to rotate. The suction pipe 66 forms negative pressure suction in the middle tube 63, and quickly sucks out the dust and impurities on the contact surface of the fixed substrate 9 and the pulling substrate 12 through the suction head 64. The suction pipe 66 here is an elastic telescopic tube, so it will not affect the rotation and movement of the middle tube 63, and can quickly remove dust and ash from the contact surface of the fixed substrate 9 and the pulling substrate 12 before testing, so as to avoid dust and impurities accumulating on the contact surface of the fixed substrate 9 and the pulling substrate 12, which will cause the viscosity of the adhesive to be weakened, thereby affecting the accuracy of the test results.

[0038] The PLC controller 14 drives the adjusting motor 33 to move according to the estimated value of the adhesive strength. The greater the estimated value of the adhesive strength, the longer the driving time of the adjusting motor 33 is. The adjusting motor 33 drives the adjusting screw 32 to rotate, and the adjusting plate 34 is moved downward by the threaded sleeve effect of the adjusting screw 32 and the adjusting plate 34. The greater the estimated value of the adhesive strength, the greater the downward movement distance of the adjusting plate 34, thereby making the sliding distance of the adhesive-coated conductive contact 36 on the adhesive-coated resistor rod 37 greater, thereby making the access resistance of the adhesive-coated resistor rod 37 greater, and the adhesive-coated conductive contact 36 The glue coating resistor rod 37 is connected in series to the power supply circuit of the annular drive electric slide rail 71, and the annular drive electric slide rail 71 is a DC device. Therefore, the smaller the power of the annular drive electric slide rail 71, the slower the moving speed of the annular drive electric slide rail 71. After the contact surface of the fixed substrate 9 and the pulling substrate 12 is cleaned, the electric telescopic rod 62 drives the intermediate tube 63 to move back and away from between the fixed substrate 9 and the pulling substrate 12. The PLC controller 14 then controls the transverse electric slide rail 72 to drive the glue coating head 74 to move forward, so that the glue coating head 74 moves to the fixed substrate 9 and the pulling substrate. The PLC controller 14 controls the glue pump 76 to work, and the glue pump 76 cooperates with the glue tube 75 to transport the adhesive to the glue head 74, and the adhesive is coated on the fixed substrate 9. The annular drive electric slide 71 drives the glue head 74 to move, and the adhesive is evenly coated on the fixed substrate 9. The greater the expected viscosity of the adhesive, the greater the access resistance of the glue resistor rod 37, and the slower the moving speed of the annular drive electric slide 71, so that more adhesive is coated on the upper surface of the fixed substrate 9, which can be between the fixed substrate 9 and the pulling substrate 12. The adhesive is automatically coated between the substrates 12, and the coating thickness can be automatically adjusted based on the estimated value of the adhesive strength, so that the coating thickness of the adhesive with stronger viscosity is greater, which satisfies the actual situation that the adhesive with greater viscosity requires stronger adhesive force and the thickness used is also thicker, while the adhesive with less viscosity also requires less adhesive force and the thickness used is relatively thinner. The coating thickness can be automatically adjusted according to the actual situation, so that the adhesive test of the adhesive is more in line with the actual situation, so that the test result can obtain more realistic feedback;

[0039] After the gluing is completed, the PLC controller 14 controls the transverse electric slide rail 72 to drive the gluing head 74 to move backward, so that the gluing head 74 is separated from the fixed substrate 9 and the pulling substrate 12. The PLC controller 14 then controls the electric push rod 11 to push the pulling substrate 12 downward until the pulling substrate 12 contacts the fixed substrate 9. During the continued downward movement of the lifting plate 41, the anti-slip rod 42 drives the anti-slip plate 43 to move upward relative to the lifting plate 41 until the anti-slip plate 43 acts on the confirmation switch 46. At this time, the PLC controller 14 controls the electric push rod 11 The push-down action continues. At this time, the PLC controller 14 controls the power supply device to supply power to the thrust electromagnetic plate 57. The thrust electromagnetic plate 57 is energized to generate magnetism to cooperate with the thrust permanent magnet plate 56 to provide a downward pressure to the pressure plate 55. The pressure plate 55 pushes the pressure roller 54 through the pressure rod 53 to provide an extrusion force to the pulling substrate 12. The PLC controller 14 then controls the circular transfer electric slide rail 51 to drive the pressure roller 54 to move in an annular manner, providing a stable extrusion force to the upper surface of the pulling substrate 12, thereby making the pulling substrate 12 and the fixed substrate 9 close to each other. The space between the fixed substrate 9 and the pulling substrate 12 is fully squeezed, so that the adhesive is better bonded between the fixed substrate 9 and the pulling substrate 12, and when the expected adhesive strength value of the adhesive is greater, the moving distance of the pressurized conductive contact piece 39 on the pressurized resistor rod 38 is also greater, so that the resistance value of the pressurized resistor rod 38 is smaller, and the pressurized conductive contact piece 39 and the pressurized resistor rod 38 are connected in series to the power supply circuit of the thrust electromagnetic plate 57, so at this time, the greater the power supply current of the thrust electromagnetic plate 57, the stronger the magnetism of the thrust electromagnetic plate 57, so that the thrust electromagnetic plate 57 cooperates with the thrust permanent magnet plate 5 6. The pair of pressure rollers 54 provide a greater pressure, thereby achieving a greater pressure on the pulling substrate 12, and can automatically adjust the pressure of the adhesive applied to the fixed substrate 9 and the pulling substrate 12 according to the expected value of the adhesive strength of the adhesive. A greater pressure is used for the adhesive with high viscosity to ensure that the adhesive can be evenly distributed between the two test substrates and fit tightly, while a smaller pressure is used for the adhesive with low viscosity to avoid the problem that a large extrusion force easily causes excessive overflow of the adhesive, which is not conducive to the stability of bonding;

[0040] After providing pressure to the pulling substrate 12 for 5 minutes, the PLC controller 14 first cuts off the power supply to the thrust electromagnetic plate 57, and at the same time the PLC controller 14 controls the electric push rod 11 to drive the fixed shell 21 to move up, and then drives the pulling substrate 12 to move up synchronously through the lifting plate 41. The pulling substrate 12 provides a downward pulling force to the lifting plate 41 due to the bonding force of the adhesive, which counteracts the upward pulling force of the electric push rod 11, so that the lifting plate 23 cooperates with the lifting rod 22 to overcome the elastic force of the strong spring 24 and move downward relative to the fixed shell 21. When the adhesive strength of the adhesive meets the standard, the downward pulling force of the lifting plate 41 caused by the bonding force of the adhesive can enable the lifting plate 23 to overcome the elastic force of the strong spring 24 and act on the in-place switch 35 at the upper end of the adjustment plate 34. At this time, the in-place switch 35 feedbacks a signal to the PLC controller 14, and the PLC controller 14 controls the alarm 13 to make a sound to remind the staff that the inspection meets the standard.

[0041] The pressurized conductive contact 39 and the pressurized resistor rod 38 are also connected in series to the power supply circuit of the first force electromagnetic plate 86. The first force electromagnetic plate 86 is energized to generate magnetism and cooperate with the first force-bearing permanent magnet plate 85 to push the push plate 83 to move upward along the guide slide bar 81 to overcome the elastic force of the downward pressure spring 84. Specifically, the greater the expected viscosity strength value of the adhesive, the smaller the access resistance value of the pressurized resistor rod 38, thereby making the magnetism of the first force electromagnetic plate 86 stronger, and the upward movement distance of the push plate 83 greater. In this process, the PLC controller 14 controls the power supply device to supply power to the suction electromagnetic plate 811. The suction electromagnetic plate 811 is energized to generate magnetism and cooperate with the suction permanent magnet plate 810 to drive the outer expansion plate 89 and the trigger rod 88 to move upward, so that the trigger rod 88 is located at the uppermost position;

[0042] In the process of the lifting plate 23 moving downward relative to the fixed shell 21, the feedback conductive contact 25 also slides on the feedback resistor rod 26. Specifically, the greater the relative downward movement distance of the lifting plate 23, the greater the sliding distance of the feedback conductive contact 25 on the feedback resistor rod 26, thereby making the access resistance of the feedback resistor rod 26 smaller. In addition, the feedback conductive contact 25 and the feedback resistor rod 26 are also connected in series to the power supply circuit of the second force electromagnetic plate 817. The second force electromagnetic plate 817 is energized to generate magnetism and cooperate with the second force permanent magnet plate 816 to drive the bottom support plate 815 along the resistance rod. 814 overcomes the friction resistance of the resistance rod 814 and moves upward, and the farthest distance that the feedback conductive contact piece 25 moves up and down on the feedback resistance rod 26 is fed back to feedback the minimum access resistance of the second force electromagnetic plate 817, and then the maximum magnetic force of the second force electromagnetic plate 817 is fed back, so that the bottom support plate 815 moves up to the maximum height. When the lifting plate 23 cannot contact the in-place switch 35 after the pulling substrate 12 and the fixed substrate 9 are relatively separated, it means that the bonding force of the adhesive is not up to standard. At this time, the PLC controller 14 cuts off the power supply to the suction electromagnetic plate 811, and the outer expansion plate 89 The trigger rod 88 moves downward under the action of its own weight until the lower end of the trigger rod 88 contacts the upper end of the bottom support plate 815. At this time, the trigger rod 88 stops moving downward. During the downward movement of the outer expansion plate 89, the pressing round head 812 on one side of the outer expansion plate 89 acts on the warning switch 813. When the distance between the bottom support plate 815 and the push plate 83 increases, the downward movement distance of the trigger rod 88 increases, so that the pressing round head 812 can act on the warning switch 813 further down, indicating that the adhesive strength of the currently detected adhesive is different from the expected adhesive strength. The larger the value, the more the warning switch 813 on the lower side controls the alarm 13 to prompt the staff that the difference value is larger, and the size of the difference value is recorded through the PLC controller 14 in conjunction with the memory, which can directly feedback and display the viscosity strength value of the adhesive, and calculate and feedback the difference with the expected viscosity strength value of the adhesive, so that the feedback test data is more comprehensive and accurate, and the optimization direction of the adhesive performance is clearer, which can enable the staff to better target the improvement of the adhesive and improve the research and development efficiency and improvement effect of the adhesive.
