Description

Technical Field

[0001] The utility model specifically discloses an ACF product slippage testing device. Background Art

[0002] Currently, ACF products in the industry need to undergo a slip test. However, in the existing technology, the slip test is mostly performed manually. The manual test method involves fixing the test reel with one hand and pulling the ACF product with the other hand (tightening it outward along the winding direction of the ACF product), so that the ACF product is partially pulled out of the test reel and the ACF product wound on the test reel is tightened until the ACF product feels loose and slips. The force felt at this time is then scored for slipping. This test method relies entirely on manual feel to judge the test results, which may result in misjudgment or inaccurate judgment, and there is no accurate test data. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide an ACF product slippage testing device in response to the above-mentioned deficiencies in the prior art. The ACF product slippage testing device can avoid the situation in which manual testing is prone to inconsistent pulling angles and forces, reduce the occurrence of misjudgments, and improve the stability and reliability of the test.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] An ACF product slippage test device includes a tension component, a clamping and fixing component, and a tension recorder. The ACF product is wound on a test reel. The clamping and fixing component is used to clamp and fix the test reel to prevent the test reel from rotating during the test. The tension component is connected to the end of the ACF product extending out of the test reel and is used to apply tension to the ACF product so that the ACF product wound on the test reel shrinks and is tightened until the ACF product and the test reel slip. The tension recorder is electrically connected to the tension component and is used to record the tension applied by the tension component.

[0006] Preferably, the tension assembly adopts a tension machine, the top of the tension machine is provided with a chuck for clamping the ACF product, and the clamping and fixing assembly is installed at the bottom of the tension machine.

[0007] Preferably, the chuck and the clamping and fixing assembly are located in the same vertical plane.

[0008] Preferably, the clamping and fixing assembly includes a fixed shaft, a clamping claw, and a fixed support. The fixed shaft passes through the center hole of the test reel and is fixedly connected to the fixed support. One end of the clamping claw is fixedly connected to the fixed shaft, and the other end is clamped on the outer circumference of the test reel. The diameter of the fixed shaft is the same as the diameter of the center hole of the test reel, and the length of the clamping claw is the same as the radius of the test reel.

[0009] Preferably, one end of the clamping claw connected to the outer circumference of the test roll is in the shape of a hook.

[0010] Preferably, the clamping and fixing assembly includes a fixed shaft and a sliding base. There are two sliding bases, which are arranged opposite to each other and can slide relative to each other along a slide rail arranged at the bottom of the tensile machine. A first through hole is also provided on the sliding base. The positions of the two sliding bases are adjusted so that the two sliding bases clamp the two sides of the test reel and keep the first through hole aligned with the center hole of the test reel. The fixed shaft passes through the first through hole and the center hole in turn, and the two ends are fixedly connected to the sliding base by nuts.

[0011] Preferably, sponge pads are provided on the opposite inner sides of the two sliding bases.

[0012] The clamping assembly of this ACF product slip tester secures the test reel. A tensioning assembly tightens the ACF product, causing it to slip against the test reel. A tension recorder records the tension during slippage, effectively avoiding the inconsistent tension and angles that can occur during manual testing, further preventing misjudgments.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] The utility model provides an ACF product slippage testing device, comprising a tension component, a clamping and fixing component, and a tension recorder. The ACF product is wound on a test reel. The clamping and fixing component is used to clamp and fix the test reel to prevent the test reel from rotating during the test. The tension component is connected to the end of the ACF product extending out of the test reel and is used to apply tension to the ACF product so that the ACF product wound on the test reel is contracted and tightened until the ACF product and the test reel slip. The tension recorder is electrically connected to the tension component and is used to record the tension applied by the tension component.

[0022] Example 1

[0023] This embodiment discloses an ACF product slippage test device, comprising a tension assembly, a clamping assembly, and a tension recorder. A test reel 100 is circular, with an annular groove defined on its outer circumference. ACF products 110 are wound within the groove of the test reel 100, with the innermost ACF product 110 attached to the test reel 100. The ACF products 110 are then wound around the test reel 100 in successive turns, with the ACF products 110 at the end extending outward from the test reel 100.

[0024] In this embodiment, a clamping assembly is used to clamp and secure the test reel 100, preventing it from rotating during testing. A tension assembly is located above the test reel 100 and is connected to the end of the ACF product 110 extending from the test reel 100, thereby applying tension to the ACF product 110, causing the ACF product 110 wound on the test reel 100 to shrink and tighten until the ACF product 110 and the test reel 100 begin to slip. A tension recorder is electrically connected to the tension assembly to record the tension applied by the tension assembly. The tension recorded by the tension recorder is used to determine whether the tension is within the standard range, thereby determining whether the ACF product 110 meets the requirements.

[0025] like Figure 1 As shown, the tensioning assembly utilizes a tensile testing machine 200. A chuck 210 is mounted on the top of the tensile testing machine 200 to clamp the ACF product 110. The clamping assembly is mounted on the bottom plate of the tensile testing machine 200. Furthermore, the chuck 210 and the clamping assembly are located in the same vertical plane, ensuring that the chuck 210 always maintains a vertically upward angle to pull the ACF product 110, thereby maintaining a constant tension angle. Furthermore, the use of the tensile testing machine 200 ensures the stability of the applied tension.

[0026] like Figure 2 As shown, the clamping and fixing assembly optionally includes a fixed shaft 310, a clamping jaw 320, and a fixed support 300. The fixed shaft 310 passes through the center hole of the test reel 100 and is fixedly connected to the fixed support 300. One end of the clamping jaw 320 is fixedly connected to the fixed shaft 310, and the connection method can be welding, bolt connection, or other fixed connection methods. The other end of the clamping jaw 320 is hook-shaped and is clamped on the outer circumference of the test reel 100 to grip the outer circumference of the test reel 100.

[0027] Specifically, the diameter of the fixed shaft 310 is the same as the diameter of the center hole of the test reel 100, ensuring that the fixed shaft 310 can be clamped to the test reel 100 after being inserted into the center hole of the test reel 100. The length of the clamping jaws 320 is the same as the radius of the test reel 100, ensuring that the clamping jaws 320 can be firmly clamped to the outer circumference of the test reel 100. The clamping of the fixed shaft 310 to the center hole of the test reel 100 and the clamping of the clamping jaws 320 to the outer circumference of the test reel 100 ensure that the test reel 100 is fixed and prevented from rotating during the test process.

[0028] Optionally, the fixed shaft 310 and the central hole may also be in the form of interference fit, and the length of the clamping jaw 320 may be set to be slightly smaller than the radius of the test reel 100 .

[0029] Two fixing supports 300 are arranged opposite to each other, and a second through hole is provided on each of the two fixing supports 300. Both ends of the fixing shaft 310 pass through the second through holes on the two fixing supports 300 and are connected to the fixing supports 300. The connection method is bolt connection.

[0030] like Figure 3 As shown, as another embodiment, the clamping and fixing assembly includes a fixed shaft 310 and a sliding base 330. Two sliding bases 330 are provided. The two sliding bases 330 are arranged opposite to each other and can slide relatively along the slide rail 340 arranged on the bottom plate of the tensile machine 200. In addition, a first through hole is provided on the sliding base 330. The positions of the two sliding bases 330 are adjusted so that the two sliding bases 330 clamp the two sides of the test reel 100 and keep the first through hole aligned with the center hole of the test reel 100. The fixed shaft 310 passes through the first through hole and the center hole in turn, and the two ends are fixedly connected to the sliding base 330 by nuts, thereby fixing the test reel 100.

[0031] Furthermore, sponge pads are provided on the inner sides of the two sliding bases 330 , which are used to provide a buffering effect when the sliding bases 330 come into contact with the side of the test reel 100 , thereby preventing the sliding bases 330 from squeezing and damaging the test reel 100 .

[0032] The use process of the ACF product slip test device in this embodiment is as follows:

[0033] Use a clamping fixture to securely mount the test reel 100 on the bottom of the tensile testing machine 200;

[0034] Pull out the ACF product 110 for a certain distance and fix its end on the chuck 210 on the upper part of the tensile testing machine 200;

[0035] Turn on the tensile testing machine 200 and apply tension to the ACF product 110 through the chuck 210 to start the test;

[0036] The tension value of the ACF product 110 when it slips is recorded by a tension recorder, and whether the ACF product 110 meets the requirements is determined based on the tension value.

[0037] Existing manual testing methods rely entirely on the tester's feel, resulting in no accurate test data and relying entirely on subjective scoring. During the test, the tester must manually pull, using inconsistent force and angles, leading to deviations in the pulling force applied to the ACF product. Furthermore, the force felt by different testers varies, potentially leading to inconsistent test results and misjudgments. Furthermore, manual testing results in a small number of tests and is inefficient. The tester's hands are easily injured during prolonged pulling, which also leads to fatigue and affects their perception of force.

[0038] The clamping assembly of the ACF product slippage test device in this embodiment secures the test reel 100. The tension assembly tightens the ACF product 110, causing it to slip against the test reel 100. A tension recorder records the tension during slippage, effectively avoiding the inconsistent tension and angles that can occur during manual testing, further preventing misjudgments. The tension assembly continuously and effectively outputs a stable tension, ensuring the accuracy of test results. The tension recorder's tension value range allows the ACF product 110 to be judged as meeting the requirements.

[0039] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
