Embodiment 2

[0073] see image 3 , is a schematic structural diagram of a second peeling tester provided by an embodiment of the present invention, the peeling tester includes: a load cell 201, an analog-to-digital converter 202, a first micro-control unit 203, a flash memory chip 301, and a second micro-controller Unit 302, where:

[0074] The load cell 201 is connected to the analog-to-digital converter 202 , the analog-to-digital converter 202 is connected to the first micro-control unit 203 , the flash memory chip 301 is connected to the first micro-control unit 203 , and the second micro-control unit 302 is connected to the flash memory chip 301 .

[0075] The analog-to-digital converter 202 is used to convert the force value collected by the load cell 201 into a discrete digital signal;

[0076] The first micro-control unit 203 is used to sort the discrete digital signals according to the size of the discrete digital signal values, obtain the intermediate value of the sorting result...

Embodiment 3

[0086] see Figure 4 , is a schematic structural diagram of the adjustable shoe last in the above-mentioned peel tester disclosed in the embodiment of the present invention, and the adjustable shoe last includes:

[0087] Front fixing block 1, bolt 2, adjusting nut 3, rear fixing block 4, rear shoe last 5 and front shoe last 6, wherein:

[0088] The front fixing block 1 is arranged in the front shoe last 6, the front fixing block 1 is provided with a threaded hole, the rear fixing block 4 is arranged in the rear shoe last 5, the rear fixing block 4 is provided with a through hole, and the bolt 2 penetrates through the front. The threaded hole in the fixed block 1 and the through hole in the rear fixed block 4, the bolt 2 is used to connect the front fixed block 1 and the rear fixed block 4, the bolt 2 matches the threaded hole in the front fixed block 1, and the adjustment nuts are 3 sets It is arranged on the bolt 2 and is located between the front fixing block 1 and the rea...

Embodiment 4

[0096] The embodiment of the present invention provides a peeling test knife in the above-mentioned peeling tester, and the peeling test knife includes:

[0097] The rib-shaped protrusions and the mounting holes at the end of the pressing surface of the peeling test knife.

[0098] Preferably, the figure 1 The pressure surface is divided into three pressure surfaces: the first pressure surface, the second pressure surface and the third pressure surface. The relationship between the first pressure surface, the second pressure surface and the third pressure surface is as follows: Figure 5 to Figure 10 shown. Of course you can only Figure 5 to Figure 10 the end of the first pressing surface (ie figure 1 The end of the medium pressure surface 102) is improved, and the figure 1 The pressure surface is divided into a first pressure surface, a second pressure surface and a third pressure surface.

Abstract

The embodiment of the invention discloses a peeling test method and a peeling test device. The peeling test device comprises: a force transducer acquiring force values in the peeling process of a shoe to be tested; an analog-to-digital (A-D) converter which is connected with the force transducer and converts the force values into discrete digital signals; and a first micro-control unit which is connected with the A-D converter, orders the discrete digital signals according to the size of the discrete digital signal values to obtain a medium value of an ordering result, and adopting the medium value as an effective peeling strength value corresponding to the current displacement of the shoe to be tested. By adopting the peeling test method and the peeling test device provided in the embodiment of the invention, errors generated through human judgment can be avoided, the peeling strength value of the shoe to be tested can be accurately tested, and the peeling strength value can be obtained by obtaining adhesion defects and the adhesion capability in the effective width of an adhesive layer through analyzing a displacement-strength value curve no longer just by the generation of early adhesive cracking.

Description

technical field [0001] The invention relates to data processing, and more particularly, to a peeling test method and a peeling tester. Background technique [0002] The peel tester is used to test the adhesion of the adhesive layer between the sole and the upper. The peel tester includes a peel test knife, figure 1 is the cross-sectional view of the peeling test knife in the prior art, from figure 1 It can be seen that the peeling test knife includes: the pressing surface 101, the pressing surface end 102, the inclined surface 103 and the mounting hole 104. The process of using the peeling test knife to peel off the shoe to be tested is as follows: [0003] First, place the pressure surface end 102 of the peeling test knife on the sole of the shoe to be tested and the adhesive layer of the upper. During the peeling process, the pressure surface end 102 separates the sole from the upper. At this time, it is necessary to overcome the sole With the adhesive force between the ...
