[0039] During the production process of the diaphragm, it is necessary to detect the degree of bulging of the diaphragm roll. In this regard, the prior art provides a detection device for detecting the bulging of the diaphragm roll. The diaphragm roll is installed vertically on the frame. The driver is used to drive the connecting piece to reciprocate vertically. The connecting piece is used to connect the laser detection mechanism, so that the laser detection mechanism can move vertically along with the connecting piece to detect the degree of bulging at different positions of the diaphragm roll. However, the problem is that the axis of the diaphragm roll is parallel to the vertical direction, which easily causes the diaphragm roll to tip over, the installation is unstable, and the detection data is prone to errors.

[0040] In view of the above problems, this embodiment provides a detection device to solve the problems that in the detection device of the prior art, the axis of the diaphragm roll is parallel to the vertical direction, which easily causes the diaphragm roll to tip over, the installation is unstable, and the detection data is prone to errors. It can be used in the technical field of diaphragm detection.

[0041] Referring to Figures 1 - 5 , the detection device includes a support mechanism 1, a drive mechanism 2, and a detection mechanism 3. The support mechanism 1 is used to support the diaphragm roll so that the axis of the diaphragm roll extends along a first direction parallel to the horizontal plane, thereby supporting the diaphragm roll in the horizontal direction, which can avoid the diaphragm roll from tipping over and improve the stability of the support. The drive mechanism 2 is arranged on the support mechanism 1; the detection mechanism 3 includes a slider 31 slidably arranged on the support mechanism 1 along the first direction, a light emitter 32 arranged on the slider 31, and a light receiver 33 arranged on the slider 31. The drive mechanism 2 is used to drive the slider 31 to reciprocate along the first direction. The light emitter 32 is used to emit light, and the light receiver 33 is used to receive light. The light emitter 32 and the light receiver 33 are respectively located on the radial two sides of the diaphragm roll, so that part of the light emitted by the light emitter 32 irradiates on the outer peripheral wall of the diaphragm roll, and the other part of the light directly irradiates on the light receiver 33 and is received by the light receiver 33. Furthermore, a shadow of the outer peripheral wall of the diaphragm roll can be displayed on the light receiver 33, and this shadow shows the contour of the outer peripheral wall of the diaphragm roll. The height change of the contour of the outer peripheral wall of the diaphragm roll can be obtained by reading the light and dark changes of the shadow on the light receiver 33, and the degree of bulging of the diaphragm roll can be judged accordingly.

[0042] Referring to Figure 6, the detection mechanism further includes a control device 4, and both the light emitter 32 and the light receiver 33 are communicatively connected to the control device 4. Specifically, the control device 4 can be used to control the light emitter 32 to emit light. Subsequently, the control device 4 reads the data received by the light receiver 33 and obtains the highest point and the lowest point of the outer peripheral wall contour of the diaphragm roll. The degree of rib bursting is judged by the difference between the two. In some embodiments, the data received by the light receiver 33 can also be segmented by the control device 4, and the height difference between the highest point and the lowest point of the outer peripheral wall contour of the diaphragm roll for each segment is obtained in sequence, so as to judge the degree of rib bursting for each segment. In this way, the position where the rib bursting occurs can be determined when the rib bursting occurs, and the detection accuracy can be improved.

Or, after completing the detection of the upper side wall of the diaphragm roll, both the light emitter 32 and the light receiver 33 are transferred to the lower part to perform burst rib detection on the lower side wall of the diaphragm roll.

[0051] Optionally, the first vertical plate 312 is provided with a first guide rail 3122 in the vertical direction, and the light emitter 32 is slidably disposed on the first vertical plate 312 along the vertical direction through the first guide rail 3122; the second vertical plate 313 is provided with a second guide rail 3131 in the vertical direction, and the light receiver 33 is slidably disposed on the second vertical plate 313 along the vertical direction through the second guide rail 3131.

Thus, when performing detection, the relative position between the light emitter 32 and the first vertical plate 312 can be locked, and the relative position between the light receiver 33 and the second vertical plate 313 can be locked, and unlocked after the detection is completed. Optionally, the first locking member 34 is a first locking screw, and the first locking screw is threadedly inserted through the light emitter 32 and can be abutted against the first vertical plate 312 to lock the relative position between the light emitter 32 and the first vertical plate 312; the second locking member 35 is a second locking screw, and the second locking screw is threadedly inserted through the light receiver 33 and can be abutted against the second vertical plate 313 to lock the relative position between the light receiver 33 and the second vertical plate 313.
