before the adhesive tape 81 passes through between the first positioning plate 42 and the second positioning plate 43, the side surface of the first positioning plate 42, which is close to the second positioning plate 43, is coplanar with the side surface of the fixed disc 21, which is close to the movable disc 23, and the side surface of the second positioning plate 43, which is close to the first positioning plate 42, is coplanar with the side surface of the movable disc 23, which is close to the fixed disc 21;
the detection device further comprises a first power mechanism 5, and the first power mechanism 5 is used for driving the clamp 4 to move towards the glue discharging mechanism 2 during detection, so that the adhesive tape 81 and the glued plate 3 form an angle of 180 degrees, and peel strength detection is performed.
After the movable tray 23 is removed, the roll of tape 8 may be wound around the support roller 22, and then the movable tray 23 may be mounted on the support roller 22, such that the fixed tray 21 and the movable tray 23 are respectively contacted with both sides of the roll of tape 8, and the movable tray 23 may be mounted on the support roller 22 by means of threads, as shown in fig. 1 and 2. The adherend 3 is a stainless steel plate for attaching the adhesive tape 81.
In the above technical solution, the fixing component 44 may adopt a mode that the cylinder drives the pressing block, and the adhesive tape 81 is pressed on the panel 41 by the pressing block to fix the adhesive tape 81.
In the above technical scheme, the first power mechanism 5 includes a third driving component 50 and a fourth driving component 51, the fourth driving component 51 is mounted at an output end of the third driving component 50, the clamp 4 is mounted at an output end of the fourth driving component 51, the third driving component 50 is used for driving the clamp 4 to move towards the glue discharging mechanism 2, and the fourth driving component 51 is used for driving the clamp 4 to move vertically. Wherein the third driving part 50 and the fourth driving part 51 may be linear motors, screw-nut devices, air cylinders, etc.
In fig. 10, the adhesive tape 81 is shown as being distorted, the arrow indicates the peeling direction, the peeling position between the adhesive tape 81 and the adherend 3 is the peeling line 82, and the peeling line 82 is not perpendicular to the longitudinal direction of the adhesive tape 81, that is, the length is large.
In this embodiment, the specific implementation manner is as follows: firstly, the adhesive tape roll 8 is sleeved on the supporting roller 22, the fixed disc 21 and the movable disc 23 are respectively contacted with two sides of the adhesive tape roll 8, then the adhesive tape 81 on the adhesive tape roll 8 is pulled towards the direction of the clamp 4, the adhesive tape 81 passes through the space between the first positioning plate 42 and the second positioning plate 43, namely as shown in fig. 1 and 2, then the adhesive tape 81 is pressed on the panel 41 through the fixing component 44, and finally the peeling strength detection is carried out. In the detection, the driving part III 50 drives the clamp 4 to move towards the glue discharging mechanism 2, so that the adhesive tape 81 can form an angle of 180 degrees with the glued plate 3, and the detection is started after the movement is continued after the angle of 180 degrees is formed. The purpose of driving the clamp 4 to move vertically by the driving part four 51 is to prevent the problem that the clamp 4 collides with the adhered plate 3 in the moving process. Before the adhesive tape 81 passes through the first positioning plate 42 and the second positioning plate 43, the side surface of the first positioning plate 42 on the side close to the second positioning plate 43 is made coplanar with the side surface of the fixed disk 21 on the side close to the movable disk 23, and the side surface of the second positioning plate 43 on the side close to the first positioning plate 42 is made coplanar with the side surface of the movable disk 23 on the side close to the fixed disk 21, the purpose is to make the distance between the first positioning plate 42 and the second positioning plate 43 equal to the width of the adhesive tape 81 so as to be positioned, that is, the adhesive tape 81 is in a pulled state when both sides of the adhesive tape 81 are in contact with both side walls of the first positioning plate 42 and the second positioning plate 43. In this way, when the peel strength is detected, the peeling line 82 when the adhesive tape 81 and the adherend 3 are peeled off is perpendicular to the length direction (or peeling direction) of the adhesive tape 81, so that the peeling line 82 is exactly equal to the width of the adhesive tape 81, and the problem of greater peel strength due to the lengthening of the peeling line 82 and the increase of the peeling force is avoided.

Because the distance between the glue discharging mechanism 2 and the clamp 4 is far, when the adhesive tape 81 is pulled to the position of the clamp 4, the cross section of the adhesive tape can generate an arc shape, and at this time, gaps are reserved between the two sides of the adhesive tape 81 and the first positioning plate 42 and the second positioning plate 43, and the adhesive tape cannot be contacted and cannot be positioned. Therefore, when the adhesive tape 81 is pulled to the position of the clamp 4, firstly, the non-adhesive surface of the adhesive tape 81 is attached to the bottom of one pressing plate 442 close to the releasing mechanism 2, the vacuum generator is used for vacuumizing, the adhesive tape 81 is adsorbed on the other pressing plate 442 by adopting the same method, and it is noted that the adhesive tape 81 between the two pressing plates 442 should be straightened, and the adhesive tape 81 is straightened again due to the closer distance between the two pressing plates 442, so that the arc shape generated by the cross section of the adhesive tape is eliminated, so that the two sides of the adhesive tape 81 are conveniently contacted with the first positioning plate 42 and the second positioning plate 43 to facilitate positioning.

Referring to fig. 4 of the specification, the detection device further includes a second power mechanism 6, the second power mechanism 6 includes a mounting plate 61, the mounting plate 61 is mounted on the platform 1, the mounting plate 61 is vertically mounted with a belt transmission part 62, a belt of the belt transmission part 62 is fixedly mounted with a connecting seat 63, and the fixing plate 21 is fixedly mounted on the connecting seat 63.
