The strip film is stretched and detected, the strip film is directly detected, the problems that the strip film is required to be cut firstly and then is placed on an instrument for detection, the film is inclined and inaccurate in detection are avoided, in the process of cutting and stretching detection of the film, the detection rod II 9 pushes the strip plate II 10 to descend, the two strip plates 10 descend to be in contact with the film, the strip plate II is matched with the middle and rear discharge plates 3 to clamp the film, the cutter 108 ascends to cut the film, the strip film is clamped by the strip plate II 10 and the discharge plates 3, the strip film bottom is adhered to the middle and rear discharge plates 3 due to the downward pressing of the strip plate II 10, then bolts 8 on the two strip plates 10 are twisted, the lower clamping blocks 11 positioned below the strip plate II 10 are fixed together with the strip plate II 10, the strip film is clamped at two sides, the detection rod II 9 drives the strip plate II 10 and the lower clamping blocks 11 to ascend, the strip plate II and the strip plate II is clamped by the strip plate II and the strip plate II is pulled by the cutter 108, and the strip plate II is clamped by the strip plate II and the strip plate II is pulled to be in contact with the strip plate 3, and the strip plate 3 is separated from the strip plate 3, and the strip film can not be adhered to the strip film is separated, and the strip film is adhered to the strip film and the strip film is separated from the strip film by the strip plate 3 and the strip film by the strip film and the strip film 3 and the strip film is stretched and detected;
the heating piece in the rear discharging plate 3 starts to work, the first rear pressing plate 5 is heated and conducts heat to the film, so that the film heats, the difference of the adhesiveness of the film when heated and unheated is observed, the heating scene of the mobile phone is simulated, the adhesiveness of the film is detected more accurately when the mobile phone heats, the problem that the film needs to be cut firstly when the film is placed in the prior art and then placed on an instrument for detection, the film is inclined, and meanwhile, various detection can be carried out on the film according to the specific use scene of the film;
because the adhesion detection is needed, after the film is placed by a worker, the film cannot be placed on the discharging plate 3 flatly due to manual placement, partial area arching or wrinkling can possibly occur, the film cannot be clung to the discharging plate 3, partial bubbles can occur between the film and the discharging plate 3 after the pressing plate II 10 is pressed down, the film cannot be completely adhered to the discharging plate 3, and further detection errors are caused, when the push rod IV 113 pushes the upper clamping plate 104 to descend, the film is slightly extruded on the lower clamping plate 103 through the upper clamping plate 104, namely the fastening degree of the upper clamping plate 104 and the lower clamping plate 103 for clamping the film is not high, meanwhile, the upper clamping plate 104 descends to drive the clamping block 105 to be clamped with the corresponding clamping block 106, so that the upper clamping plate 104 and the lower clamping plate 103 are fixed together, and then the push rod III 111 pushes the upper clamping plate 104 to move away from the film through the connecting plate II 112 and the push rod IV 113, so that the lower clamping plate 103 and the upper clamping plate 104 drive the film to move, and four sides of the film are driven to move, so that the film 103 is accurately pushed by the upper clamping plate 103 to be pushed by the four sides, and the lower clamping plate 103 is pushed by the supporting plate 103 to move away from the center of the supporting plate 103, and the compression point of the lower clamping plate 103 is avoided, and the compression phenomenon is avoided, and the expansion and compression of the compression rod 103 is accurate is avoided, and the expansion and compression of the clamping plate 103 is caused by the lower clamping plate 102;
but because the membrane has certain adhesion, so the membrane is easy to adhere on the lower plate 103, at this moment, the distance that the four sides of the membrane moved will be as far as the lower plate 103, and the lower plate 103 drives the membrane to move and can not judge the pulling distance again, if the pulling distance is too far, the membrane will be too tight, and the membrane is stretched more likely, and then the accuracy of membrane adhesion detection is affected, so before placing the membrane, the push rod four 113 will push the upper plate 104 down first, and the distance that the upper plate 104 descends is controlled through the inductor, the distance between the upper plate 104 and the lower plate 103 is made smaller, then the water supply equipment supplies water to the water spraying holes 104a, so that the water is sprayed out from the water spraying holes 104a, and then the water is attached to the lower surface of the upper plate 104 and the upper surface of the lower plate 103, then the push rod four 113 pushes the upper plate 104 to lift to the original position, and after that the lower plate 103 and the upper plate 104 are in driving the membrane to move, because there is a layer of water between the membrane and the lower plate 103, the membrane can not adhere tightly on the lower plate 103, and the upper plate 103 is enabled to pull the membrane and the upper plate 104 in advance, and the accuracy of membrane can not be affected when the membrane is pulled and the upper plate 104 is pulled, and the accuracy of membrane is not pulled and the lower plate 104 is not pulled, and the problem is solved when the membrane is not pulled is detected.

Each second pressing plate 10 is provided with a communication hole 10a, and the communication holes 10a are used for spraying gas, so that the gas pushes the film when the gas is sprayed out, and further, the film and the second pressing plates 10 are prevented from being adhered together, and the error of detection precision is caused.
Also included are dispersible tablets 202; each of the two pressing plates 10 has a dispersion plate 202 fixedly connected to the outlet of the communication hole 10a, and each dispersion plate 202 has nine air outlet holes, so that the air sprayed out is dispersed by the dispersion plate 202, and the coverage area of the air is more comprehensive.
The specific working steps are as follows:
first, the peripheral air supply device is connected to the communication hole 10 a;
because the film has adhesiveness, the film can be adhered on the blanking plate 3, and if the first blanking plate 5, the upper clamping block 7 and the lower clamping block 11 drive the film to rise to carry out stretching detection, the film can be stretched to influence the accuracy of the stretching detection of the film because the film is adhered to the blanking plate 3, the first concave groove 3a and the second concave groove 5a are respectively arranged on the front blanking plate 3 and the first blanking plate 5, so that when the front blanking plate 3 and the first blanking plate 5 clamp the film, the film has a small contact area with the first blanking plate 3 and the first blanking plate 5, the adhesiveness between the film and the front blanking plate 3 is small, and when the first blanking plate 5 clamps the film to rise to carry out stretching detection, the film can be rapidly separated from the blanking plate 3, the condition that the film is stretched and deformed is avoided, and the accuracy of the stretching detection is ensured;
the film adhesion detection is to separate the film from the adhesion object by using a certain force, record the required force and the stripping speed in the process, and be used for evaluating the adhesion performance of the film, and when the second pressing plate 10 is arranged below, the film can be adhered to the lower surface of the second pressing plate 10 when the film is adhered to the middle and rear discharging plates 3, when the second pressing plate 10 is lifted, the second pressing plate 10 pulls the middle part of the film to lift up, so that the middle part area of the film is pulled up, the phenomenon of incomplete adhesion between the middle part area of the film and the rear two discharging plates 3 is caused, and further, the adhesion detection is caused to be wrong, so that when the second pressing plate 10 is lifted up, the peripheral air supply equipment can also supply air to the communication hole 10a, further, the film is separated from the second pressing plate 10, thereby solving the problem that the middle part of the film is lifted up, the film is not completely adhered to the rear two discharging plates 3, and further, the problem of inaccurate film adhesion detection is avoided, and further, the detection accuracy is ensured;
before placing the film, the second detection rod 9 drives the second pressing plate 10 to descend, so that the second pressing plate 10 descends to the position above the discharging plate 3 and then stops descending, and then the peripheral air supply equipment supplies air to the communication hole 10a, so that the air is sprayed out of the communication hole 10a, the sprayed air cleans the surface of the discharging plate 3 below, the phenomenon that the film is not tightly adhered due to dust is avoided, sprayed air is in a dispersed state through the dispersing sheets 202, the coverage area of the sprayed air is more comprehensive, and the effect of cleaning the surface of the discharging plate 3 is better.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
