Description

Technical Field

[0001] This invention belongs to the technical field of new material testing devices, specifically a viscosity testing device for cover tape production. Background Technology

[0002] Cover tape is a strip-shaped product used in the field of electronic packaging. It is used in conjunction with carrier tape and can be sealed to the surface of carrier tape under external force or heat, forming a closed space inside the carrier tape to protect the electronic components inside.

[0003] Viscosity testing is required during the production of cap tape to ensure that its viscosity performance meets the requirements, thereby guaranteeing its reliability and effectiveness in different application scenarios and preventing failures. Meanwhile, during the viscosity testing of cap tape for new material testing, the tape is clamped in the fixture by rotating a screw. In practical applications, the tape is easily pulled out during testing if the screw is not rotated fully, leading to test failure. Furthermore, adhesive residue is easily left on the fixture after testing, making it difficult to clean. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a viscosity testing device for cover tape production. This device utilizes an adsorption plate to apply adhesive or attach the cover tape, and adds a self-adhesive silicone layer to the adsorption plate. This increases the thickness of the clamping blocks for clamping and fixing, improving the fixing effect and preventing the adsorption plate or cover tape from slipping during the testing process. This facilitates viscosity testing and improves testing accuracy. At the same time, it isolates the adhesive on the adsorption plate, making it easier to clean residual adhesive.

[0005] The technical solution adopted by the present invention to solve its technical problem is: the viscosity detection device for cap tape production of the present invention includes a main body, a controller is installed on the right end of the main body, and a clamping mechanism and a detection mechanism are installed on the left end of the main body; The clamping mechanisms are arranged in pairs. Each clamping mechanism includes a lifting plate, and an mounting plate is installed at the lower end of the lifting plate. An electric push rod is installed inside the main body, and the electric push rod drives the mounting plate to move up and down. An installation frame is installed on the lifting plate, a tension sensor is installed between the lifting plate and the installation frame, a clamping block is installed on the installation frame, an adjusting rod is installed on the clamping block, an adsorption plate is installed between the clamping blocks, adhesive is applied to the lower surface of the adsorption plate or a test strip is installed, and the detection mechanism is located in the middle of the two clamping mechanisms. The detection mechanism includes a mounting base on which a pressure sensor is mounted. The pressure sensor is in contact with the test strip. The mounting base is mounted on a slide rail, and the slide rail is perpendicular to the adsorption plate.

[0006] Preferably, the mounting base is equipped with multiple sets of pressure sensors, which are evenly arranged along the length of the adsorption plate. The clamping mechanism includes a symmetrically arranged left clamping head and a right clamping head, which are raised and lowered by their respective independent electric push rods.

[0007] Preferably, a self-adhesive silicone layer is installed on the lower surface of the adsorption plate, and the test strip is placed and attached to the self-adhesive silicone layer.

[0008] Preferably, the self-adhesive silicone layer is arched, the test strip first contacts the self-adhesive silicone layer in the middle of the adsorption plate, and then the test strip contacts the self-adhesive silicone layers at both ends of the adsorption plate, and the surfaces of the multiple pressure sensors are matched with the surfaces of the self-adhesive silicone layers.

[0009] Preferably, the self-adhesive silicone layer has air gap grooves, and the length direction of the air gap grooves is perpendicular to the length direction of the self-adhesive silicone layer.

[0010] Preferably, the adsorption plate squeezes the pressure sensor before the detection begins, and the squeezing force on the pressure sensor is within a preset range.

[0011] Preferably, the clamping block includes an upper plate and a lower plate, the adjusting rod passes through the upper plate and the lower plate, a positioning groove is formed on the lower surface of the upper plate, and the adsorption plate is magnetically attracted and fixed in the positioning groove, the depth of the positioning groove being less than or equal to the thickness of the adsorption plate.

[0012] Preferably, a spacer is movably mounted on the upper surface of the lower plate, and a smooth Teflon tape is adhered to the surface of the spacer.

[0013] The beneficial effects of this invention are as follows: 1. The viscosity testing device for cap tape production described in this invention, by setting up clamping blocks, an adsorption plate, a self-adhesive silicone layer, and pressure sensors, allows the new material cap tape to adhere to the adsorption plate, ensuring that the new material cap tape is straight, free of air bubbles and wrinkles, so as not to affect the accuracy of subsequent viscosity testing results. At the same time, the thickness of the adsorption plate and the self-adhesive silicone layer is superimposed with the thickness of the new material cap tape, thereby facilitating the clamping block to clamp and fix the new material cap tape, avoiding the situation where the thickness of the new material cap tape to be tested is small, and the new material cap tape is not firmly fixed and slips off during the testing process, affecting the smooth progress of the testing. In addition, multiple sets of pressure sensors can detect multiple sets of parallel data at the same time, thereby reducing systematic errors, avoiding random errors, and improving the accuracy of viscosity testing results.

[0014] 2. The viscosity testing device for cap tape production described in this invention, by setting up an upper plate, a positioning groove, a lower plate, a separating sheet, and a self-adhesive silicone layer, places the adsorption plate into the positioning groove, which facilitates the accurate placement of the adsorption plate by the operator and avoids the adsorption plate from being skewed or offset, thus affecting the accuracy of the test results of the new material cap tape. At the same time, through the action of the separating sheet, Teflon tape, and self-adhesive silicone layer, the new material cap tape or the adhesive applied is relatively isolated from the clamping mechanism, avoiding glue residue after testing that is difficult to clean.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1 to 6 As shown, the viscosity testing device for cap tape production according to the present invention includes a main body 1, a controller 11 is installed on the right end of the main body 1, and a clamping mechanism and a testing mechanism are installed on the left end of the main body 1. The clamping mechanisms are arranged in pairs. Each clamping mechanism includes a lifting plate 2. An mounting plate 21 is installed at the lower end of the lifting plate 2. An electric push rod 22 is installed inside the main body 1. The electric push rod 22 drives the mounting plate 21 to move up and down. An installation frame 3 is installed on the lifting plate 2. A tension sensor 34 is installed between the lifting plate 2 and the installation frame 3. A clamping block 32 is installed on the installation frame 3. An adjusting rod 31 is installed on the clamping block 32. An adsorption plate 5 is installed between the clamping blocks 32. Adhesive is applied to the lower surface of the adsorption plate 5 or a test strip 6 is installed thereon. The detection mechanism is located in the middle of the two clamping mechanisms. The detection mechanism includes a mounting base 41, on which a pressure sensor 4 is mounted. The pressure sensor 4 is in contact with the test strip 6. The mounting base 41 is mounted on a slide rail 411, and the slide rail 411 is perpendicular to the adsorption plate 5. During the production of cover tape, when testing new materials, it is necessary to test the viscosity of the new material cover tape or adhesive to ensure that the viscosity of the new material cover tape meets the design requirements, so as to ensure its reliability and effectiveness in different application scenarios and avoid failure. If the adhesive viscosity is detected by detecting the force between the pressure sensor 4 and the adhesive, the worker evenly applies the adhesive to the adsorption plate 5, then installs the adsorption plate 5 between the clamping blocks 32, and uses the threaded adjusting rod 31 to rotate, so that the clamping blocks 32 come closer together and clamp the adsorption plate 5. Then, the worker controls the electric push rod 22 to start running through the controller 11, which drives the mounting plate 21, the lifting plate 2, the mounting frame 3, and the clamping blocks 32 to start descending, so that the adhesive on the adsorption plate 5 comes into contact with the pressure sensor 4. Then, the worker controls the electric push rod 22 to run in the opposite direction through the controller 11, so that the adsorption plate 5, the adhesive, and the pressure sensor 4 separate from each other, thereby detecting the viscosity data of the adhesive through the pressure sensor 4. When using a ball bearing to test the adhesive's viscosity, the adhesive is evenly applied to the adsorption plate 5 with the adhesive side facing upwards. Then, the adsorption plate 5 is installed between the clamping blocks 32. Next, the controller 11 controls the adsorption plate 5 to gradually descend and contact the pressure sensor 4. At the same time, the controller 11 controls the clamping mechanisms on both sides to descend at different heights, causing the adsorption plate 5 to tilt. Then, the operator releases the ball bearing from the higher end of the adsorption plate 5, allowing the ball bearing to roll over the adhesive surface and detect the data from the pressure sensor 4, thereby obtaining the adhesive's viscosity data. Similarly, when testing the viscosity of the new material cover strip, the test strip 6 is attached to the adsorption plate 5. Then, the viscosity of the new material cover strip is tested in the two ways mentioned above. At the same time, the two ends of the test strip 6 and the two ends of the adsorption plate 5 are squeezed and clamped by the clamping block 32 to prevent the test strip 6 from loosening and slipping during the test, which would lead to test failure. Meanwhile, a tension sensor 34 is installed between the mounting frame 3 and the lifting plate 2. The tension sensor 34 detects the force exerted on the adsorption plate 5 during the detection process, and the data from the tension sensor 34 is integrated to improve the accuracy of viscosity detection. Meanwhile, the mounting base 41 is installed on the slide rail 411. When different models of new material cover strips are tested and the pressure sensor 4 needs to be replaced, the staff will move the mounting base 41 along the slide rail 411 so that the mounting base 41 is relatively away from the clamping mechanism, which makes it easier for the staff to replace and maintain the pressure sensor 4. Meanwhile, by using the adsorption plate 5 to place and fix the new material cover strip to be tested, the strip 6 to be tested can be kept straight between the two clamping mechanisms, avoiding the situation of the strip 6 to be tested being skewed, stretched or loosened when placed, thus avoiding affecting the accuracy of the test results, and facilitating the installation and removal of the strip 6 to be tested on the testing device. Meanwhile, there are two types of adsorption plates 5. The first type of adsorption plate 5 has greater strength and is not easily bent or deformed during the testing process. This type of adsorption plate 5 is used in the test of detecting the force between the pressure sensor 4 and the adhesive to detect the adhesiveness. The second type of adsorption plate 5 has relatively less strength and is relatively easy to deform. Therefore, when this type of adsorption plate 5 is used in the test of detecting adhesiveness using balls, if the lowering height of the clamping mechanisms on both sides is inconsistent, the position of the adsorption plate 5 near the clamping mechanism is prone to deformation and tilting, so that the balls can roll off the adsorption plate 5.

[0019] In one embodiment of the present invention, a plurality of pressure sensors 4 are installed on the mounting base 41, and the pressure sensors 4 are evenly arranged along the length direction of the adsorption plate 5. The clamping mechanism includes a symmetrically arranged left clamping head and a right clamping head, which are raised and lowered by their respective independent electric push rods 22; By setting multiple sets of pressure sensors 4, multiple sets of parallel detection data can be collected during a single viscosity detection process, whether the ball is rolling or the adhesive is separating from the pressure sensor 4. This reduces systematic errors and avoids the impact of random errors on the accuracy of the detection results, thereby improving the accuracy of the detection results. Meanwhile, in the test of detecting the force between the pressure sensor 4 and the adhesive to detect the adhesiveness, since the left clamping head and the right clamping head are raised and lowered by independent electric push rods 22 respectively, the clamping heads on both sides are raised and lowered at the same time during the test to detect the overall adhesiveness of the adhesive on the test strip 6 or adsorption plate 5. Alternatively, a ball bearing can be used to test the adhesive's viscosity, which facilitates adjusting the height difference between the two clamping heads and thus changing the tilt angle of the adsorption plate 5, ensuring smooth viscosity testing and guaranteeing testing accuracy.

[0020] In one embodiment of the present invention, a self-adhesive silicone layer 51 is installed on the lower surface of the adsorption plate 5, and the test strip 6 is placed and attached to the self-adhesive silicone layer 51. The self-adhesive silicone layer 51 is used to adhere and fix the test strip 6, preventing it from becoming loose or sagging when placed on the surface of the adsorption plate 5. This facilitates the installation and fixation of the test strip 6. At the same time, the self-adhesive silicone layer 51 increases the force between the test strip 6 and the adsorption plate 5, preventing the test strip 6 from detaching from the adsorption plate 5 and ensuring smooth testing. In addition, the self-adhesive silicone layer 51 further enhances the clamping and fixing effect of the clamping block 32 on the adsorption plate 5 and the test strip 6, making the thickness of the test strip 6 relatively increase. This facilitates the clamping and fixing of the clamping block 32 and prevents the test strip 6 from slipping off at both ends when subjected to force during testing. Meanwhile, the self-adhesive silicone layer 51 isolates the adhesive applied to the adsorption plate 5, preventing the adhesive from directly adhering to the adsorption plate 5 and facilitating the cleaning of the adhesive adhering to the adsorption plate 5 after testing.

[0021] In one embodiment of the present invention, the self-adhesive silicone layer 51 is arched, the test strip 6 first contacts the self-adhesive silicone layer 51 in the middle of the adsorption plate 5, and then contacts the self-adhesive silicone layer 51 at both ends of the adsorption plate 5. The surfaces of the multiple pressure sensors are matched with the surfaces of the self-adhesive silicone layer. During testing, the test strip 6 is relatively long. During its attachment to the adsorption plate 5, wrinkles or air bubbles can easily form on the test strip 6, affecting its placement and fixation, and consequently the accuracy of the subsequent viscosity test results. Therefore, by using an arched self-adhesive silicone layer 51, when the operator holds both ends of the test strip 6 and attaches it to the adsorption plate 5, the test strip 6 will first contact the middle of the adsorption plate 5, and then the two ends. This sequential contact between the test strip 6 and different positions on the adsorption plate 5 prevents wrinkles or air bubbles from forming on the test strip 6, ensuring that the test strip 6 is tightly and straight on the adsorption plate 5, thus guaranteeing the accuracy of the subsequent test results. Simultaneously, by adjusting the installation height of each set of pressure sensors 4, the upper ends of multiple sets of pressure sensors 4 form a downward arched shape, ensuring that the pressure between the pressure sensors 4 and various points on the self-adhesive silicone layer 51 is the same.

[0022] In one embodiment of the present invention, an air gap groove 511 is formed on the self-adhesive silicone layer 51, and the length direction of the air gap groove 511 is perpendicular to the length direction of the self-adhesive silicone layer 51. By creating tiny air gaps 511, during the process of attaching the test strip 6 to the adsorption plate 5, the air between the wide test strip 6 and the adsorption plate 5 will be quickly vented along the air gaps 511, minimizing the formation of air bubbles between the test strip 6 and the adsorption plate 5, which would affect the accuracy of the viscosity test results. At the same time, the air gaps 511 relatively increase the contact area between the test strip 6 and the adsorption plate 5, improving the placement and fixation of the test plate on the adsorption plate 5, reducing the occurrence of the test strip 6 being pulled or separating from the adsorption plate 5 during the test, and ensuring smooth test performance.

[0023] In one embodiment of the present invention, the adsorption plate 5 squeezes the pressure sensor 4 before the detection begins, and the squeezing force on the pressure sensor 4 is within a preset range. The controller 11 controls the electric push rod 22, causing the electric push rod 22 to move the adsorption plate 5 downwards before the test begins. This causes the adsorption plate 5 to bring the test strip 6 into contact with and press against the pressure sensor 4 until the pressure exerted by the adsorption plate 5 on the pressure sensor 4 is within a preset range. At this point, the adhesive on the test strip 6 exerts the same pressure on each pressure sensor 4, meaning that the adhesion between each pressure sensor 4 and the test strip 6 is consistent. This further reduces the error in viscosity detection and improves the accuracy of the test results for the new material. At the same time, the pressure exerted by the adsorption plate 5 on the pressure sensor 4 can calibrate the data between each pressure sensor 4 and the tension sensor 34, ensuring that the reference of each sensor is consistent during the test and improving the accuracy of the test results for the new material. In addition, since the shape of the upper end of the pressure sensor 4 matches the shape of the self-adhesive silicone layer 51, the arched part on the self-adhesive silicone layer 51 is prevented from increasing the pressure on the pressure sensor 4, which would affect the consistency of the adhesion between each pressure sensor 4 and the test strip 6 and increase the error in viscosity detection.

[0024] In one embodiment of the present invention, the clamping block 32 includes an upper plate 321 and a lower plate 322, the adjusting rod 31 passes through the upper plate 321 and the lower plate 322, a positioning groove is provided on the lower surface of the upper plate 321, and the adsorption plate 5 is magnetically attracted and fixed in the positioning groove, the depth of the positioning groove is less than or equal to the thickness of the adsorption plate 5. After applying adhesive to the adsorption plate 5 or attaching the test strip 6 to the adsorption plate 5, the operator places the adsorption plate 5 into the positioning groove on the upper plate 321, so that the adsorption plate 5 can be stably placed between the clamping blocks 32. This avoids the need for the operator to manually lift the adsorption plate 5 during the clamping and fixing process, thereby preventing accidental movement by the operator that could cause the adsorption plate 5 and the test strip 6 to become misaligned relative to the pressure sensor 4, resulting in a reduced contact area or insufficient contact between the test strip 6 and the pressure sensor 4, thus avoiding affecting the accuracy of the test results.

[0025] In one embodiment of the present invention, an isolation plate 33 is movably mounted on the upper surface of the lower plate 322, and a smooth Teflon tape is pasted on the surface of the isolation plate 33. An isolation plate 33 is installed on the lower plate 322, and Teflon tape is installed on the isolation plate 33 to isolate the adhesive on the test strip 6. This prevents residual adhesive from appearing on the clamping block 32 after clamping and fixing the test strip 6 and the adsorption plate 5 and after the test is completed. At the same time, since the Teflon tape is in contact with the adhesive on the test strip 6, it can avoid adhesive residue. In addition, if there is adhesive residue, the isolation plate 33 can be removed, the old Teflon tape can be peeled off, and a new Teflon tape can be replaced. This makes it easy to clean and replace the surface of the isolation plate 33, avoiding the problem of small operating space between the clamping blocks 32, which makes it difficult to operate, and the problem of wrinkles appearing on the Teflon tape.

[0026] The specific workflow is as follows: During the production of the cover tape, when testing new materials, it is necessary to test the viscosity of the new material cover tape or adhesive to ensure that the viscosity of the new material cover tape meets the design requirements. If the adhesive viscosity is detected by detecting the force between the pressure sensor 4 and the adhesive, the worker evenly applies the adhesive to the adsorption plate 5, then installs the adsorption plate 5 between the clamping blocks 32, and uses the threaded adjusting rod 31 to rotate, so that the clamping blocks 32 come closer together and clamp the adsorption plate 5. Then, the worker controls the electric push rod 22 to start running through the controller 11, which drives the mounting plate 21, the lifting plate 2, the mounting frame 3, and the clamping blocks 32 to start descending, so that the adhesive on the adsorption plate 5 comes into contact with the pressure sensor 4. Then, the worker controls the electric push rod 22 to run in the opposite direction through the controller 11, so that the adsorption plate 5, the adhesive, and the pressure sensor 4 separate from each other, thereby detecting the viscosity data of the adhesive through the pressure sensor 4. When using a ball bearing to test the adhesive's viscosity, the adhesive is evenly applied to the adsorption plate 5 with the adhesive side facing upwards. Then, the adsorption plate 5 is installed between the clamping blocks 32. Next, the controller 11 controls the adsorption plate 5 to gradually descend and contact the pressure sensor 4. At the same time, the controller 11 controls the clamping mechanisms on both sides to descend at different heights, causing the adsorption plate 5 to tilt. Then, the operator releases the ball bearing from the higher end of the adsorption plate 5, allowing the ball bearing to roll over the adhesive surface and detect the data from the pressure sensor 4, thereby obtaining the adhesive's viscosity data. Similarly, when testing the viscosity of the new material cover strip, the test strip 6 is attached to the adsorption plate 5, and then the viscosity of the new material cover strip is tested in the two ways mentioned above. At the same time, the two ends of the test strip 6 and the two ends of the adsorption plate 5 are squeezed and clamped together by the clamping block 32. Meanwhile, a tension sensor 34 is installed between the mounting frame 3 and the lifting plate 2 to detect the force exerted on the adsorption plate 5 during the detection process. Meanwhile, the mounting base 41 is installed on the slide rail 411. When different models of new material cover strips are tested and the pressure sensor 4 needs to be replaced, the staff will move the mounting base 41 along the slide rail 411 so that the mounting base 41 is relatively away from the clamping mechanism, which makes it easier for the staff to replace and maintain the pressure sensor 4. Meanwhile, by using the adsorption plate 5 to place and fix the new material cover strip to be tested, the strip 6 to be tested can be kept straight between the two clamping mechanisms; Meanwhile, there are two types of adsorption plates 5. The first type of adsorption plate 5 has greater strength and is not easily bent or deformed during the testing process. This type of adsorption plate 5 is used in the test of detecting the force between the pressure sensor 4 and the adhesive to detect the adhesiveness. The second type of adsorption plate 5 has relatively less strength and is relatively easy to deform. Therefore, when this type of adsorption plate 5 is used in the test of detecting adhesiveness by ball bearings, if the lowering height of the clamping mechanisms on both sides is inconsistent, the position of the adsorption plate 5 near the clamping mechanism is prone to deformation and tilting, so that the ball bearings can roll off the adsorption plate 5. By setting multiple sets of pressure sensors 4, multiple sets of parallel detection data can be collected during a single viscosity detection process, whether the ball is rolling or the adhesive is separating from the pressure sensor 4, thus reducing systematic and random errors. Meanwhile, in the test of detecting the force between the pressure sensor 4 and the adhesive to detect the adhesiveness, since the left clamping head and the right clamping head are raised and lowered by independent electric push rods 22 respectively, the clamping heads on both sides are raised and lowered at the same time during the test to detect the overall adhesiveness of the adhesive on the test strip 6 or adsorption plate 5. Alternatively, a ball bearing can be used to test the adhesive's viscosity, which facilitates adjusting the height difference between the two clamping heads and thus changing the tilt angle of the adsorption plate 5, making viscosity testing easier and ensuring accuracy. The test strip 6 is adhered and fixed by the self-adhesive silicone layer 51. At the same time, the self-adhesive silicone layer 51 increases the force between the test strip 6 and the adsorption plate 5, preventing the test strip 6 from separating from the adsorption plate 5. In addition, the self-adhesive silicone layer 51 relatively increases the thickness of the test strip 6, which facilitates the clamping and fixing of the clamping block 32. At the same time, the self-adhesive silicone layer 51 is used to isolate the adhesive applied to the adsorption plate 5. Because the self-adhesive silicone layer 51 is arched, when the operator pinches both ends of the test strip 6 and attaches it to the adsorption plate 5, the test strip 6 will first contact the middle position of the adsorption plate 5, and then contact the two ends of the adsorption plate 5. By the sequential contact of the test strip 6 with different positions on the adsorption plate 5, wrinkles or air bubbles in the test strip 6 are avoided. At the same time, the upper surface of each pressure sensor 4 matches the surface of the self-adhesive silicone layer 51. By creating tiny air gaps 511, during the process of attaching the test strip 6 to the adsorption plate 5, the air between the wide test strip 6 and the adsorption plate 5 will be quickly discharged along the air gaps 511. At the same time, the air gaps 511 increase the contact area between the test strip 6 and the adsorption plate 5. The controller 11 controls the electric push rod 22, which moves the adsorption plate 5 downward before the test begins. This causes the adsorption plate 5 to bring the test strip 6 into contact with and press the pressure sensor 4 until the pressure of the adsorption plate 5 on the pressure sensor 4 is within a preset range. At this point, the adhesive on the test strip 6 exerts the same pressure on each pressure sensor 4, meaning that the adhesion between each pressure sensor 4 and the test strip 6 is consistent. This further reduces the error in viscosity detection. At the same time, the pressure of the adsorption plate 5 on the pressure sensor 4 can calibrate the data between each pressure sensor 4 and the tension sensor 34, ensuring that the reference of each sensor is consistent during the test. After applying adhesive to the adsorption plate 5 or attaching the test strip 6 to the adsorption plate 5, the staff places the adsorption plate 5 into the positioning groove on the upper plate 321 so that the adsorption plate 5 can be stably placed between the clamping blocks 32. An isolation plate 33 is installed on the lower plate 322, and Teflon tape is installed on the isolation plate 33 to isolate the adhesive on the test strip 6.
