Description

Technical Field

[0001] This invention proposes a device for testing the initial tack of adhesive tape, which belongs to the field of adhesive tape testing equipment. Background Technology

[0002] Currently, the initial tack of adhesive tape is tested using a rolling ball method adhesive tape initial tack tester. However, this tester occupies a large space, is inconvenient to store, and is placed on a laboratory table. The laboratory table is very wide and non-adjustable, which is not friendly to small-statured testers and makes them more prone to fatigue. In addition, the experimental data is still recorded manually, and the test tape needs to be cut and fixed manually, resulting in low testing efficiency. The existing laboratory table is generally adjusted vertically, which is very restrictive when horizontal adjustment is required. The space utilization of the laboratory is low. To solve the above problems, there is an urgent need for an easy-to-store, adjustable-size adhesive tape initial tack testing device to improve testing efficiency. Summary of the Invention

[0003] To address the technical problems existing in the prior art, the present invention proposes a tape initial tack testing device, the technical features of which are as follows:

[0004] A device for testing the initial tack of adhesive tape includes a test plate, a test platform, a test frame, and a data component. The test plate has a cutting part, which includes a cutting groove and a cutting blade. The test platform includes a test seat and a test slide plate. The test seat includes a tensile fixing component and a rotating tensile support. The data component includes a data acquisition component and a data analysis component. The tensile fixing components of the test plate and the test seat are detachably connected to the test frame. The test frame includes a lateral adjustment part, a longitudinal adjustment part, and a vertical adjustment part. Each adjustment part consists of an inner tube column and an outer tube column. A tensile component is located between the inner tube column and the outer tube column. The inner tube column and the outer tube column are interlocked and movable. The end of the interlocking joint has an annular groove filled with steel balls. The steel balls are located separately in a steel ball groove. An elastic component connects the steel ball groove and the annular groove.

[0005] Preferably, the cutter includes a rotating and folding blade head and blade body, and the test plate has cutting grooves on its surface and four sides, and segmented cutting grooves are provided on the vertical side surface of the test plate.

[0006] Preferably, the tension fixing component and the rotating tension support are movably connected, one end of the test slide is connected to the rotating tension support, and the other end is connected to the tension fixing component. The test plate, the tension fixing component and the test slide share a common rotating shaft group, and a rotation angle display device is provided at both ends of a single rotating shaft.

[0007] Preferably, the maximum distance after stretching of the tension fixing component is greater than the length of the test slide, the outer width of the test slide is less than the inner width of the tension fixing component, the frame of the tension fixing component forms a hollow groove, the thickness of the tension fixing component is greater than the total thickness of the test slide and the rotating tension bracket, the hollow groove fits into the test slide and the rotating tension bracket, and limit plates are distributed at the four corners of the fit.

[0008] Preferably, a movable tight-fitting block is provided at the connection between the test slide and the rotating tension bracket, and a spring-loaded device is provided between the movable tight-fitting block and the inner wall of the test slide.

[0009] Preferably, the tension fixing assembly includes a movable tension rod, a movable fixing plate, a fixing groove, and a spring. The movable fixing plate is located at the end of the movable tension rod, and the movable fixing plate and the fixing groove are elastically connected.

[0010] Preferably, at least one of the test slide plates has a groove, and an arc-shaped connector is provided at the connection between the groove of the test slide plate and the test plate. One end of the connector is connected to the groove of the test slide plate, and the other end is horizontally connected to the test plate.

[0011] Preferably, the inner tube of the vertical adjustment section is solid, the outer tube is hollow, the tensioning assembly is an electro-hydraulic rod, and a sliding fixing device is provided at the bottom of the vertical adjustment section.

[0012] Preferably, the inner tube head of the lateral adjustment section and the longitudinal adjustment section is fixed with a ruler spring, a reel, a brake pad and a test steel belt, and the other end of the test steel belt is fixed to the outer tube head.

[0013] Preferably, the longitudinal adjustment part and the lateral adjustment part share a power source, and the power source has two power shafts. The power shafts are connected to the horizontal axle wheel and the steering axle wheel respectively. The axle wheels of the same type are connected by a chain, and the upper side of the inner tube column has a toothed groove that mates with the axle wheel in the same direction.

[0014] The beneficial effects of this invention are as follows:

[0015] By setting a cutting component on the test plate, the tape on the production line can be laid directly onto the test plate, and the tape can be quickly cut and divided. The blade head and blade body can rotate and fold, which facilitates the cutting of the test tape, makes it easy to divide the test tape into sections, facilitates the comparison of tape test data, and reduces the time spent on manually fixing the tape.

[0016] Meanwhile, the test base is equipped with a fixed tension component, which can adjust the position of the test base and the test slide plate, making it easy to adjust the falling height of the test ball. The tension fixing component includes a movable tension rod, a fixing plate, a fixing groove and a spring, which can easily adjust the length of the test base. The combination of the spring and the fixing plate will also prevent the test base from loosening.

[0017] The hollow groove of the test seat fits into the test slide plate. The test seat and the test slide plate occupy the same space volume. The rotating tension bracket is designed to easily fix the test slide plate and facilitate the collection and reading of the falling height of the test steel ball. When stored, it also shares a space with the test seat, reducing the storage space volume of the test platform. The test plate, test slide plate and tension fixing components are fixed to the same rotating axis group, which can be folded and rotated 180 degrees or 360 degrees to adapt to different situations and facilitate storage.

[0018] By incorporating ball bearing grooves, the test balls are protected from deviating from the test trajectory, reducing test errors. The ball bearing storage component facilitates the storage and recording of ball bearing data, enabling convenient test data calculation. An arc-shaped connector is provided at the connection between the test slide groove and test plate 1 to adjust the direction of the test balls entering the test plate to a horizontal direction, preventing excessive deflection angle between the test plate and the test slide from causing the balls to pop out or impairing the test speed.

[0019] The hollow groove of the fixed tension component fits into the test slide and the rotating tension bracket, reducing the storage volume when closed, and the rotating angle scale display device can easily read the opening and closing angle of the test seat and the test slide, facilitating data acquisition.

[0020] The data acquisition component can quickly collect test data instead of manually, while the data analysis component uses machine learning to obtain more accurate test results.

[0021] By setting up horizontal, vertical, and longitudinal stretching sections, the distance adjustment in the three directions of length, width, and height can be achieved. The bottom of the inner column of the vertical stretching section is equipped with a sliding fixing device to reduce the friction of horizontal and longitudinal stretching.

[0022] The inner tube of the vertical tension section is solid to enhance the load-bearing capacity of the tension frame, while the outer tube is hollow to allow for the placement of an electro-hydraulic rod between the inner and outer tubes. The electro-hydraulic rod has strong load-bearing capacity, smooth movement, and is easy to operate.

[0023] The transverse and longitudinal tensioning sections are equipped with three core components based on the size of the support and the required tensioning force. This provides a tensioning frame that is easy to operate, has stable load-bearing capacity, and is safe and reliable. Different core components can be selected according to the load capacity to achieve cost savings.

[0024] The tensioning assembly is set as an electro-hydraulic rod combination, which is suitable for situations where the tensioning bracket has a large volume and mass load.

[0025] The tensioning assembly is a combination of a ruler spring, a reel, a brake pad, and a test steel belt. It is suitable for tensioning supports that can be easily pulled manually, and has the effect of convenient tensioning, fixing, and rapid rebound. At the same time, the scale on the test steel belt can record the tensioning distance in a timely manner.

[0026] The tensioning assembly is set as a shaft and wheel combination, suitable for tensioning brackets with light to medium volume and weight. The power source input is realized through manual rotating wheel or reduction motor. The power source drives the gear and connecting shaft to move synchronously. The connecting shaft is set so that the lateral or longitudinal tensioning can be carried out synchronously. At the same time, it drives the gear groove of the outer tube column to complete the quick tensioning of the bracket.

[0027] The tensile fixing components of the test plate and test seat are detachably connected to the test frame, making the test equipment easy to operate. Testers can adjust it according to their own habits or the tensile frame according to the test equipment used, providing testers with a suitable test environment, reducing interference factors during the test, increasing the convenience of the test, and speeding up the test efficiency.

[0048] Example 1

[0049] Figure 1This is a schematic diagram of the testing equipment described in this invention. The testing equipment of this invention includes a test plate 1, a test platform 2, a test frame 3, and a data component 4. The test plate 1 is provided with a cutting part 11, which includes a cutting groove 111 and a cutting blade 112. The cutting blade 112 includes a rotating and folding blade head and a blade body. The cutting blade head extends from the cutting groove 111 and pulls the cutting blade body to cut the tape, thereby obtaining tape of standard size for testing. The test plate 1 has cutting grooves 111 on its surface and all four sides. The vertical part of a single direction on the side of the test plate 1 also has segmented cutting grooves 111 for adjusting the tape cutting. The cutting blade body and the cutting blade head are movably connected to adjust the size and direction of the tape cutting. In addition, the blade body is composed of multiple stretchable cylinders. The end of the blade body can be operated manually or placed on an automated robotic arm for automated operation.

[0050] The test bench 2 includes a test base 21 and a test slide 22. The test base 21 includes a tension fixing assembly 211 and a rotating tension bracket 212. The test bench 2 of the present invention includes a test base 21 and a test slide 22. The test base 21 has a tension fixing assembly at its bottom end. The tension fixing assembly 211 includes a movable tension rod 2111, a movable fixing plate 2112, a fixing groove 2113, and a spring 2114. The movable fixing plate is located at the end of the movable tension rod. The movable fixing plate and the fixing groove are elastically connected. The springs connect the bottom ends of both sides of the tension fixing assembly. There are at least two springs. The movable tension rod 2111 passes through the movable fixing plate 2112. 112 is embedded in the fixing groove 2113 for fixing, used to precisely adjust the length of the bottom end of the test seat. The maximum distance after stretching the tension fixing component 211 is greater than the length of the test slide plate 22. The outer width of the test slide plate is less than the inner width of the tension fixing component. The frame of the tension fixing component forms a hollow groove. The thickness of the tension fixing component is greater than the total thickness of the test slide plate and the rotating tension bracket. The hollow groove fits into the test slide plate and the rotating tension bracket. Limiting pieces are distributed at the four corners of the fit to accommodate the test slide plate, so that the test slide plate is embedded in the test seat. The surface of the test plate is a smooth steel surface, or a soft sponge or rubber layer can be laid on the steel surface.

[0051] Test board 1 and test platform 2 are fixed on the same rotating bracket, and are connected by rotating the bracket. After rotation and folding, the test board and the slide of test platform 2 are horizontal. This allows for rotation and folding, making storage convenient. Alternatively, using the rotating bracket, the test board and test platform 2 can be coaxially embedded or non-coaxial. When non-coaxial, the test board and test platform 2 are fixed on the same rotating bracket and can be folded and rotated 180 degrees or 360 degrees, adapting to different situations and facilitating horizontal stacking after rotation for storage.

[0052] In this invention, the test base 21 and the test slide plate 22 are fitted together at one end and share the same fixed rotation axis. The coaxial fixed outer contour is circular. The rotating axis connecting rod is a triangular prism or a cuboid. There are rotation angle scale display devices 3 on the outer sides of both ends of the rotating axis, which are used to adjust the vertical height of the test slide plate in accordance with the rotation angle of the test slide plate. The other end of the test base 21 has a rotating tension bracket 212 embedded in the frame of the test base. The contact end between the test slide plate 22 and the rotating tension bracket 212 is provided with a movable tight contact block 221. There is a spring-loaded device 222 between the movable tight contact block 221 and the test slide plate 22. Alternatively, a groove is provided on the rotating tension bracket 212 to engage with the test slide plate for fixing the test slide plate. In addition, the rotating tension bracket 212 has a height scale display. The inner and outer layers of the test plate have scales. The scale algorithm is the outer scale plus the inner display scale. After the spring 2212 is stretched and fixed, it forms an adjustable slope triangular test platform 2. When retracted, the test slide plate and the test base are on the same horizontal plane, which is convenient for storage and saves space. At least one of the test slide plates 22 has a groove 223. The arc of the groove is greater than the arc of the maximum test ball radius. A ball storage component is provided at the top joint of the test slide groove. Its function is that when the movable opening of the ball storage device is opened, the ball enters the groove and slides from the groove onto the test base for experimental testing.

[0053] The test slide groove of test plate 1 and test platform 2 has an arc-shaped connecting component at the joint. One end of the connecting component is connected to the slide groove of the test slide, and the other end is connected to test plate 1, so that the ball slides into the test base plate from the horizontal direction, reducing energy loss and making the test data more accurate.

[0054] Data component 4 includes a data acquisition component 41 and a data analysis component 42. The testing equipment also includes the data acquisition component 41, which is used to collect test data and production data of the test tape. Experimental data acquisition uses a fixed stroboscope / phase camera to record ball displacement and time, generating test data, which is then uploaded to the data storage device. Production data acquisition involves the production department generating a production information QR code. Production data includes the tape's material composition, material ratio, process steps, and data. This information is entered and read using the QR code, then uploaded to the experimental data tape's matching storage database. The data is then transmitted wirelessly to the data analysis device, where it is analyzed. The data analysis component 42 analyzes the collected data, records multiple sets of ball data, filters and selects comprehensive data for testing, resulting in more accurate and objective data.

[0055] The tensile fixing assembly 211 of the test plate 1 and the test seat is detachably connected to the test frame 3. The test frame 3 includes a transverse adjustment part 31, a longitudinal adjustment part 32, and a vertical adjustment part 33. Each adjustment part consists of an inner tube column 34 and an outer tube column 35. A tensile assembly 36 is located between the inner and outer tube columns, allowing them to engage and move. The end of the engagement has an annular groove 37 filled with steel balls 38. Each steel ball 38 is located in a steel ball groove 381, which is a semi-hollow sphere. The inner diameter of the steel ball groove is 5%–10% larger than the inner diameter of the steel ball, and the outer diameter of the steel ball groove is 12%–15% of the inner diameter of the steel ball. The inner ring of the annular groove has a movable groove. The groove has multiple raised chambers, the spacing of which is consistent with the outer diameter of the ball groove, used to fix the ball groove. The movable groove has a range of motion of 15 degrees forward and backward. An elastic component is connected between the ball groove 381 and the annular groove 37. The elastic component is a concave compression spring 371. The open ends can fix the ball groove and the annular groove well, so that the spring will not tip over when the ball rotates. The concave part in the middle of the spring allows the ball to deflect more widely and flexibly. The inner diameter of the two open ends of the concave compression spring is 70%-90% of the outer diameter of the bottom of the ball groove, and the inner diameter of the concave part in the middle is 30%-60% of the outer diameter of the bottom of the ball groove. In this embodiment, the core of the tensioning component is an electro-hydraulic rod 361.

[0056] Each inner tube 34 has an outer diameter smaller than the inner diameter of the outer tube, with a difference of 10-100 μm. At the junction of the inner and outer tubes, there is an annular protrusion 44 and an annular groove 37. The annular groove 37 is filled with steel balls 38, which are individually located in a steel ball groove 381. An elastic component connects the steel ball groove 381 and the annular groove 37. One-fifth to one-quarter of the steel ball protrudes from the annular groove, blocking the annular protrusion 44 and achieving a sliding connection at the junction of the inner and outer tubes, resulting in uniform force distribution. The length of the outer tube 35 is slightly greater than the sum of the distance between the inner tubes 34 and the distance after the hydraulic rod retracts, ensuring that when the hydraulic rod is fully retracted, the outer tube 35 completely encloses the inner tube. When the hydraulic rod is fully extended, the outer tube wraps around the upper end of the inner tube. Each inner tube has a graduation mark, consisting of two parts: the upper part displays the current extension graduation, and the lower part displays the current extension graduation plus the length of the outer tube.

[0057] In addition, a sliding protective cover 7 is provided on the outer layer of the outer tube column 35. The sliding protective cover can be single-layered or nested in multiple layers. The distance between a single layer or multiple nested layers of the sliding protective cover is greater than the distance of the hydraulic rod or other fully extended method. After the sliding protective cover is retracted, its length is consistent with that of the outer tube column. The upper end of the sliding protective cover is slidably connected to the outer tube column 35, and the lower end of the sliding protective cover is fixedly connected to the bottom end of the inner tube column. The outer tube column 35 is engraved with dimension scale lines from top to bottom. The dimension scale is the distance of the sliding protective cover plus the lifting distance of the outer tube column. The inner tube column of the vertical adjustment part 33 is solid, and the outer tube column is hollow. The top of the inner tube column 34 and the top of the outer tube column are provided with electric hydraulic rods. The outer tube column and the inner tube column 34 are rectangular, cylindrical, elliptical, or triangular prisms. The inner tube column of the vertical adjustment part 33 is in contact with the ground. The bottom of the inner column of the vertical adjustment section 33 is provided with a sliding fixing device 331, such as a universal brake wheel; at least three nested tension columns are provided in the vertical adjustment section 33, and the positions of each part of the three nested tension columns are consistent with the positions of the internal electro-hydraulic rods 361. The power supply of the electro-hydraulic rods is connected in series, and the tension or contraction control is performed simultaneously. The moving speed of the electro-hydraulic rods is 3-5 cm / s.

[0058] Electro-hydraulic rods are also placed between the inner and outer tube columns of the longitudinal and lateral adjustment sections 31. The lateral and longitudinal electro-hydraulic rods are connected in series and controlled independently. The control ends of the vertical adjustment section 33, longitudinal adjustment section 32, and lateral adjustment section 31 are all located on the same control unit. The tension frame is operated by a single person. The tension frame control unit is equipped with a password or fingerprint unlocking device and saves commonly used test settings, such as length, width, and height data. Saved parameters can be directly selected and used, and commonly used settings can be output for quick adjustment of existing parameters. In this embodiment, the core of the longitudinal and lateral downward tensioning is an electro-hydraulic rod, which is suitable for situations where the tension support has a large volume and mass load. After the tension frame is adjusted, a thick plate can be laid flat on the tension frame as a workbench, or testing equipment can be connected to the tension frame to place the testing equipment at the most suitable height for the tester. Test tape can also be laid flat on the support for testing large pieces of tape.

[0059] Example 2

[0060] The difference between Example 2 and Example 1 is that the test plate and test platform are connected by mortise and tenon joints, with a cutting blade at the end of the joint for cutting the fixed tape after the test tape is inserted. Furthermore, the core of the internal tensioning assembly of the transverse adjustment section 31 and the longitudinal adjustment section 32 is an electro-hydraulic rod. A ruler spring 311, a reel 312, a brake pad 313, and a test steel strip 314 are fixed to the end of the inner tube column 34. The other end of the test steel strip is fixed to the end of the outer tube column. The test steel strip has dimensional markings; after manual tensioning, its position is fixed by a braking device, and the ruler spring returns to its initial position via the brake pad 13. This embodiment is suitable when the contraction force of the ruler spring 11 is greater than the horizontal movement friction of the vertical adjustment section 33. It is lightweight and compact, suitable for a tensioning bracket that can be easily pulled manually. While the test steel strip and ruler spring provide elastic recoil force, data on the test steel strip can be directly recorded. A data acquisition component can also be installed next to the test steel strip to store the recorded data and transmit it to the data analysis component via a wireless transmission module, reducing manual recording time, accelerating testing efficiency, and preserving the integrity of the test data.

[0061] Example 3

[0062] In the case of Embodiment 1, the difference between this embodiment and Embodiment 1 is that the core of the tensioning assembly of the longitudinal adjustment part 32 and the lateral adjustment part 31 is an electro-hydraulic rod. Both the longitudinal adjustment part and the lateral adjustment part use axle wheel adjustment. The longitudinal adjustment part 32 and the lateral adjustment part 31 share a power source. The power source has two corresponding power shafts. The power shafts are connected to the horizontal axle wheel 37 and the steering axle wheel 38 respectively. The power source can be selected as a manual rotary wheel or a geared motor.

[0063] The horizontal adjustment section has horizontal shaft wheels located at the head and tail ends of the inner tube column and penetrating the longitudinal adjustment section. The horizontal shaft wheel has a nested telescopic section in the middle, and the telescopic interface has a stop block and a stop groove. The two ends of the horizontal shaft wheel are arranged in a ring-shaped stepped pattern, and the smallest rings are connected by a chain 39. There is a toothed groove on the upper side of the inner tube column in the transverse direction. The outermost ring of the horizontal shaft wheel cooperates with the toothed groove on the upper side of the inner tube column in the transverse direction. Rotating the horizontal shaft wheel realizes the synchronous operation of transverse stretching.

[0064] The longitudinal adjustment section has steering axle wheels located at the head and tail ends of the inner tube column, respectively. The steering axle wheels also penetrate the transverse adjustment section. A nested telescopic section is located in the middle of the steering axle wheel, with a stop block and stop groove at the telescopic interface. The steering axle wheel has one more steering surface than the horizontal axle wheel. The two ends of the steering axle wheel are arranged in a ring-shaped stepped configuration. The steering axle wheels on the corresponding longitudinal adjustment sections are connected by a chain between the smallest rings. The upper side of the longitudinal inner tube column has toothed grooves, and the outermost ring of the steering axle wheel engages with the toothed grooves on the upper side of the longitudinal inner tube column. Rotating the horizontal axle wheel enables synchronous longitudinal stretching. The steering axle wheel, horizontal axle wheel, and drive shaft have the same module, with a tooth ratio of 5:5:1. The pressure angle is 20 degrees, and the face width coefficient of the steering axle wheel and horizontal axle wheel is 15-20.

[0065] The power source for the longitudinal and lateral adjustment sections can be a geared motor from NORD, Germany. By adjusting the reduction ratio of the gearbox, the output speed and torque of the motor can be precisely controlled. The motor power ranges from 0.12 to 55 kW, which can meet the needs of different weights and tensile speeds, and satisfy various application requirements of the test fixture.

[0066] In addition to adjusting the size of the testing equipment and obtaining a suitable testing equipment for testing personnel, the present invention also provides a matching assembly line interface for the testing equipment. When the testing equipment is adjusted to the position of the assembly line interface, the assembly line interface is connected to the tape production roll interface to introduce the test tape. The test plate 1 cuts the introduced test tape, quickly extracting the test tape for convenient testing.

This invention does not improve any software programs or methods. This invention only designs the hardware structure. The methods or software programs involved in the effects or functions achieved by the hardware structure are all implemented by those skilled in the art based on existing methods or software program design books, manuals, or product manuals, combined with the functions involved in the principles and effects of this invention, through independent program writing.
