Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for test equipment, in particular to a 90-degree peeling auxiliary tool. Background Art

[0002] 90-degree peeling aids are often used in electronic multi-purpose machines for peeling, breaking and other performance tests on FPC, adhesives, adhesive tapes, self-adhesive stickers, patches, protective films, release papers, composite films, artificial leather, woven bags, films, paper and other related products. They are also suitable for conventional mechanical performance tests and analysis studies such as stretching and peeling on various mobile phones, tablet computers and related products with a force of 1KN or below.

[0003] Due to the design reasons of ordinary 90-degree peeling tools, the peeling and stretching are affected by the weight of the tooling itself, resulting in the stretching angle not being able to reach 90 degrees or the actual data cannot be accurately detected. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a 90-degree peeling auxiliary tool, which adopts synchronous wire rope traction to effectively eliminate the weight of the auxiliary tool itself and solve the problem of unstable measurement data caused by jamming and overload detection.

[0005] The utility model is achieved through the following technical solutions:

[0006] A 90-degree peeling aid is provided, which is installed on a testing machine and includes a transverse slide for placing a sample plate. The left and right ends of the transverse slide are respectively connected with an inverted L-shaped left pressure plate and a right pressure plate. Both pressure plates are vertically threaded with clamping bolts that can abut and clamp the sample plate. A linear slide is formed on the bottom surface of the transverse slide along its length direction and a linear slider is slidably connected to the linear slide. The bottom of the linear slider is connected and fixed to the adapter on the working table of the testing machine through a slider seat. The back of the slider seat is vertically connected to a mounting bracket located between the universal testing machine and the transverse slide. A sample roller located directly above the transverse slide and perpendicular to the length direction of the transverse slide is rotatably installed on the mounting bracket. A fixed pulley is rotatably installed on the front of the slider seat. The lower end of the left pressure plate is connected with a pull rope. The pull rope passes through the fixed pulley and is connected upward to the moving beam of the testing machine through a pull rope buckle. The bottom of the moving beam is connected to a clamping mechanism for clamping one end of the sample through an S-shaped sensor.

[0007] Furthermore, the clamping mechanism includes an inverted U-shaped fixed block, which has two threaded through holes facing each other horizontally at the same position of the two U-shaped arms, and adjusting screws are respectively threadedly connected in the threaded through holes, and the two adjusting screws are respectively vertically connected to clamps for clamping the sample at the opposite ends.

[0008] The clamping mechanism uses the adjusting screws arranged on both sides of the inverted U-shaped fixing block to clamp and fix the ends of the sample using the clamping plates at the ends of the adjusting screws, effectively ensuring the stability of the test during the test peeling.

[0009] Preferably, a V-shaped groove is formed on the wheel surface of the fixed pulley for cooperating with the pull rope.

[0010] By setting the wheel surface of the fixed pulley as a V-shaped groove, it is convenient to cooperate with the pulling rope, preventing the pulling rope from escaping from the fixed pulley or shaking, which affects the accuracy of the test.

[0011] Furthermore, the two adjusting screws are respectively vertically penetrated at the two opposite ends and movably connected with sliding rods.

[0012] Sliding rods are respectively slidably provided at the two opposite ends of the two adjusting screws. The sliding rods can be used to increase the rotational torque of the adjusting screws, making it easier to rotate the adjusting screws, thereby completing the clamping and loosening of the specimen and improving the convenience of operation.

[0013] Preferably, the upper ends of the clamping bolts are connected to hand wheels.

[0014] The hand-tightening wheel facilitates the rotation of the clamping bolt, helps to quickly clamp and loosen the specimen plate, and improves the convenience of operation.

[0015] Preferably, the pull rope is a steel wire rope.

[0016] The pull rope is set as a steel wire rope to improve the overall stability, carry a larger peeling tensile load, and help ensure operational stability.

[0017] Beneficial effects of the utility model:

[0018] The utility model adopts a sliding connection mode between the linear slide rail and the linear slider at the bottom of the slide, and cooperates with the sample roller on the upper part of the slide that can deform the sample 90 degrees, which can effectively ensure that the 90-degree data is fixed accurately and effectively; on the left pressure plate on one side of the slide, the fixed pulley cooperates with the pull rope to realize synchronous pull rope traction, effectively eliminating the weight of the auxiliary device itself, and solving the problem of unstable measurement data caused by jamming and overload detection due to the weight of the auxiliary device itself.

DETAILED DESCRIPTION

[0024] To clearly illustrate the technical features of the present scheme, the present scheme will be described below through specific embodiments.

[0025] As shown in Figs. 1-3 A 90 degree peeling aid is installed on the testing machine 3, which includes a horizontal sliding table 4 for placing the sample plate 10, and the left and right ends of the horizontal sliding table 4 are respectively connected with the left pressing plate 5 and the right pressing plate 6 in inverted L shape, and the two pressing plates are respectively vertically screwed with the compression bolts 20 which can abut and compress the sample plate 10, and the upper ends of the compression bolts 20 are connected with the hand wheels 15.

[0026] The bottom surface of the horizontal sliding table 4 is formed with a linear slide rail 16 along the length direction thereof, and a linear slide block 17 is slidingly connected on the linear slide rail 16, the bottom of the linear slide block 17 is connected and fixed with the adapter 9 on the workbench of the testing machine 3 through the sliding block seat 7, the back surface of the sliding block seat 7 is vertically connected with the mounting bracket 8 which is located between the testing machine 3 and the horizontal sliding table 4, the mounting bracket 8 is rotatably installed with the sample roller 12 which is located directly above the horizontal sliding table 4 and is perpendicular to the length direction of the horizontal sliding table 4, the front surface of the sliding block seat 7 is rotatably installed with the fixed pulley 18, the wheel surface of the fixed pulley 18 is provided with a V-shaped groove matched with the pull line 14, the lower end of the left pressing plate 5 is connected with the pull line 14, in this embodiment, the pull line 14 is a steel wire rope, the pull line 14 passes through the fixed pulley 18 and is connected with the mobile beam 1 of the testing machine 3 through the pull line buckle 11 upwards, and the bottom of the mobile beam 1 is connected with the clamping mechanism for clamping one end of the sample 13 through the S-shaped sensor 19.

[0027] The clamping mechanism includes a fixed block 2 in inverted U shape, the fixed block 2 is transversely provided with two screw through holes which are opposite to each other at the same position of the two U-shaped arms, and the two screw through holes are respectively screwed with the adjusting screws 21, and the two adjusting screws 21 are respectively vertically connected with the clamping plates 22 for clamping the sample 13 at the opposite two ends.

[0028] The working process of the utility model:

[0029] The 90-degree peeling auxiliary is fixed on the universal testing machine 3, one end of the sample 13 is pasted on the sample plate 10, and then the sample plate 10 is placed on the transverse sliding table 4, and the pressing bolts 20 on the left pressing plate 5 and the right pressing plate 6 are used to press the sample plate 10.

[0030] The other end of the sample 13 is guided by the sample roller 12 and enters the fixed block 2 upward and is fixed and tightened by the two adjusting screw rods 21 and the clamping plate 22, then the pull line rope 14 is wound around the fixed pulley 18 and the pull line buckle 11 is fixed on the moving cross beam 1 of the universal testing machine 3, when the moving cross beam 1 moves, the S-shaped sensor 19 drives the clamping mechanism below to drive the sample 13 and the sample plate 10 to separate, and the S-shaped sensor 19 records and feeds back the generated force value.

[0031] The moving cross beam 1 of the universal testing machine 3 drives the pull line buckle 11 to drive the pull line rope 14 to drive the left pressing plate 5, the linear slide 17 and the linear slide rail 16 are used to slide, so that the transverse sliding table 4 slides horizontally on the linear slide rail 16, so as to eliminate the torsional force generated during peeling, if these factors are not eliminated, the sample 13 will be adhered to the sample plate 10 due to excessive force, thereby achieving the effect of 90 degrees, resulting in distortion of the 90-degree experiment.

[0032] Since the pull line buckle 11 and the pull line rope 14 do not participate in the force value generated by the sensor and the experiment, the force value interference generated by the sample weight and the assembly can be eliminated, so that the correct experimental effect is achieved.
