[0033] Referring to Figure 1 、 Figure 2 and Figure 6 As shown, the diaphragm slitting device involved in the embodiment of this application includes: a machine base 100, a winding assembly 200, and a detection device 300.

[0034] Specifically, the winding assembly 200 is arranged on the machine base 100. The winding assembly 200 includes a core 210. The detection device 300 is arranged on the machine base 100. The detection device 300 includes a detection assembly 310. A detection assembly 310 is arranged at each preset position at both axial ends of the core 210. The detection assembly 310 includes a laser generator 311 and an image acquisition member 312. The laser emitted by the laser generator 311 falls at the preset position, and the image acquisition member 312 is used to detect the image within a preset range of the core 210. The preset position is within the preset range.

[0035] Specifically, referring to Figure 2 As shown, in this embodiment, a sponge wrap 220 is wrapped on the surface of the core 210. Each axial end of the core 210 has a preset position. When the diaphragm is pasted on the core 210, both ends of the diaphragm are respectively at a preset position. At this preset position, the distance between the end of the diaphragm and the end of the sponge wrap 220 close to this end is H, satisfying: H≥10mm.

[0036] In the diaphragm slitting device of the present application, the core 210 of the winding assembly 200 is used to wind the slit diaphragm. Before winding, the diaphragm needs to be pasted onto the core 210. Since the laser emitted by the laser generator 311 can fall onto the preset position of the core 210, thus, when pasting the diaphragm, the two ends of the diaphragm can be aligned with the laser beam, so as to align the two ends of the diaphragm with the preset position of the core 210. At the same time, since the image acquisition member 312 is used to detect the image within the preset range of the core 210, and the preset position is within the preset range, thus, when pasting the diaphragm, the images of the two ends of the diaphragm can be acquired by the image acquisition member 312 to further determine whether the pasting positions of the two ends of the diaphragm are at the preset position. If the images of the two ends of the diaphragm acquired by the image acquisition member 312 show that the pasting positions of the two ends of the diaphragm are not at the preset position, the position of the diaphragm is readjusted to improve the accuracy of the placement position of the diaphragm.

[0037] Specifically, the diaphragm slitting device of the present application further includes a controller (not shown) and an alarm (not shown). The image acquisition member 312 and the alarm are both electrically connected to the controller. The image acquisition member 312 is used to send an image signal to the controller. If the image signal sent by the image acquisition member 312 shows that the two ends of the diaphragm are at the preset position, the alarm will not sound. If the image signal sent by the image acquisition member 312 shows that the two ends of the diaphragm are not at the preset position, the controller sends an alarm instruction to the alarm to make the alarm sound, and the operator readjusts the position of the diaphragm according to the alarm signal.

[0038] Specifically, in this embodiment, the image acquisition member 312 is a ccd camera.

[0039] Refer to Figure 3 and Figure 5 As shown, the detection device 300 further includes a sliding assembly 320. The sliding assembly 320 is arranged on the machine base 100. The sliding assembly 320 includes a guiding member 321 and a sliding member 322 slidably connected to the guiding member 321. The guiding member 321 extends along the axial direction of the core 210. The sliding member 322 slides along the axial direction of the core 210 relative to the guiding member 321. Each detection assembly 310 is connected to a sliding member 322.

[0040] In this embodiment, since the sliding member 322 slides axially along the core 210 relative to the guiding member 321, and each detection assembly 310 is connected to a sliding member 322, thus, the detection assembly 310 can be driven by the sliding member 322 to slide axially along the core 210. When replacing cores 210 of different sizes, the position of the detection assembly 310 can be changed according to the size change of the core 210. Similarly, when the core 210 changes its position, the position of the detection assembly 310 can be changed according to the position change of the core 210, so that the laser emitted by the laser generator 311 always falls into a preset position, and at the same time, the image collected by the image acquisition member 312 is always an image within a preset range, so that the detection assembly 310 can be applied to more winding stations to improve the applicability of the above-mentioned diaphragm slitting equipment.

[0041] Referring to Figure 4 As shown, the sliding assembly 320 further includes a protection frame 323. The protection frame 323 is arranged on the machine base 100 and extends axially along the core 210. The guiding member 321 and the sliding member 322 are both arranged inside the protection frame 323, and the laser generator 311 and the image acquisition member 312 are exposed outside the protection frame 323.

[0042] In this embodiment, the guiding member 321 and the sliding member 322 can be protected by the protection frame 323 to avoid being damaged by the external environment. At the same time, since the laser generator 311 and the image acquisition member 312 are exposed outside the protection frame 323, the protection frame 323 can be prevented from interfering with the laser generator 311 and the image acquisition member 312, so that the laser emitted by the laser generator 311 can fall into a preset position, and at the same time, the image acquisition member 312 can collect an image within a preset range.

[0043] Continuing to refer to Figure 4 As shown, the protection frame 323 is provided with an avoidance groove 3231 extending axially along the core 210. The opening 3231a of the avoidance groove 3231 faces away from the machine base 100 in the radial direction of the core 210. The guiding member 321 and the sliding member 322 are arranged on the groove wall of the avoidance groove 3231 opposite to the opening 3231a. The detection device 300 further includes a connection assembly 330. One end of the connection assembly 330 is connected to the sliding member 322, and the other end of the connection assembly 330 extends out of the avoidance groove 3231 through the opening 3231a and is connected to the laser generator 311 and the image acquisition member 312.

[0044] In this embodiment, the detection component 310 can be connected to the sliding member 322 through the connection component 330, so as to facilitate the sliding of the detection component 310 along the axial direction of the core 210. Since one end of the connection component 330 away from the sliding member 322 extends out of the avoidance groove 3231 through the opening 3231a, in this way, the laser generator 311 and the image acquisition member 312 can be exposed outside the avoidance groove 3231, so as to avoid interference of the protection frame 323 on the laser generator 311 and the image acquisition member 312, so that the laser emitted by the laser generator 311 can fall at a preset position, and at the same time, the image acquisition member 312 can acquire images within a preset range.

[0045] Referring to Figure 6 As shown, the connection component 330 further includes a first connection member 331 and a second connection member 332. One end of the first connection member 331 is connected to the sliding member 322. The other end of the first connection member 331 extends out of the avoidance groove 3231 and is rotatably connected to the second connection member 332. The second connection member 332 rotates relative to the first connection member 331 around the axial direction of the core 210. The laser generator 311 is connected to the second connection member 332.

[0046] In this embodiment, since both ends of the first connection member 331 are respectively connected to the sliding member 322 and the second connection member 332, and the laser generator 311 is connected to the second connection member 332, in this way, the connection between the sliding member 322 and the laser generator 311 can be realized through the first connection member 331. Also, since the first connection member 331 is rotatably connected to the second connection member 332, and the second connection member 332 rotates relative to the first connection member 331 around the axial direction of the core 210, in this way, when the second connection member 332 rotates relative to the first connection member 331 around the axial direction of the core 210, the second connection member 332 can drive the laser generator 311 to rotate along the axis direction of the first winding, so as to adjust the angle of the laser generator 311, so that the laser emitted by the laser generator 311 can always fall at a preset position. Also, since the end of the first connection member 331 connected to the second connection member 332 extends out of the avoidance groove 3231, in this way, interference of the protection frame 323 on the second connection member 332 can be avoided, so as to expand the rotation angle of the second connection member 332 and improve the applicable range of the laser generator 311.

[0047] Continuing to refer to Figure 6 As shown, the connection component 330 further includes a third connection member 333. One end of the third connection member 333 is connected to the sliding member 322. The other end of the third connection member 333 extends out of the avoidance groove 3231 and is connected to the image acquisition member 312.

[0048] In this embodiment, since both ends of the third connecting member 333 are respectively connected to the sliding member 322 and the image acquisition member 312, thus, the connection between the image acquisition member 312 and the sliding member 322 can be realized through the third connecting member 333. Also, since one end of the third connecting member 333 connected to the image acquisition member 312 extends out of the avoidance groove 3231, thus, interference of the protection frame 323 on the image acquisition member 312 can be avoided, so that the image acquisition member 312 can acquire images within a preset range.

[0049] Specifically, one end of the third connecting member 333 connected to the image acquisition member 312 is inclined, so that the image acquisition member 312 can be arranged towards the core 210, so that the image acquisition member 312 can acquire images within a preset range.

[0050] Refer to Figure 4 As shown in FIGS. 4 and 5, the detection assembly 310 further includes a protective cover 313, and the protective cover 313 covers the laser generator 311 and the image acquisition member 312.

[0051] In this embodiment, since the protective cover 313 covers the laser generator 311 and the image acquisition member 312, thus, the protective cover 313 can play a protective role for the laser generator 311 and the image acquisition member 312. When moving the detection assembly 310, damage to the laser generator 311 and the image acquisition member 312 caused by accidental collision can be avoided.

[0052] Specifically, in this embodiment, the protective cover 313 covers one end of the laser generator 311 away from the image acquisition member 312 along the axial direction of the core 210, one end of the image acquisition member 312 away from the laser generator 311 along the axial direction of the core 210, and one end of the laser generator 311 and the image acquisition member 312 away from the protection frame 323 along the radial direction of the core 210, so that the laser generator 311 and the image acquisition member 312 are located inside the protective cover 313, thereby realizing the protection of the laser generator 311 and the image acquisition member 312.

[0053] Refer to Figure 1 As shown in FIGS. 2 and 3, the winding assembly 200 includes a first winding assembly 230 and a second winding assembly 250. The first winding assembly 230 includes a first core 240, the second winding assembly 250 includes a second core 260, the second core 260 is arranged in parallel with the first core 240, the second winding assembly 250 and the first winding assembly 230 are arranged at intervals along the radial direction of the core 210, and the first winding assembly 230 and the second winding assembly 250 are arranged staggeredly along the axial direction of the core 210. A detection assembly 310 is arranged at a preset position at both axial ends of the first core 240 and the second core 260.

[0054] In this embodiment, since the second winding assembly 250 and the first winding assembly 230 are arranged at intervals in the radial direction of the core, and the first winding assembly 230 and the second winding assembly 250 are arranged staggeredly in the axial direction of the core 210, thus, two adjacent slit diaphragms can be wound by the first winding assembly 230 and the second winding assembly 250 respectively, so as to improve the winding efficiency of the slit diaphragms. At the same time, since a detection component 310 is arranged at a preset position at both axial ends of the first core 240 and the second core 260, thus, the placement position of the diaphragm on the first core 240 and the second core 260 can be detected by the detection component 310, so as to improve the accuracy of the placement position of the diaphragm on the first core 240 and the second core 260.

[0055] Continue to refer to Figure 1 As shown, there are multiple first winding assemblies 230 and multiple second winding assemblies 250. The multiple first winding assemblies 230 are arranged at intervals in the axial direction of the first core 240 on the machine base 100. In the axial direction of the first core 240, the multiple second winding assemblies 250 are arranged at intervals in the axial direction of the second core 260 on the machine base 100, and each first winding assembly 230 is arranged staggeredly in the axial direction of the core 210 with a second winding assembly 250.

[0056] In this embodiment, since the multiple first winding assemblies 230 are arranged at intervals in the axial direction of the first core 240 on the machine base 100, and the multiple second winding assemblies 250 are arranged at intervals in the axial direction of the second core 260 on the machine base 100, thus, multiple slit diaphragms can be wound simultaneously by the multiple first winding assemblies 230 and the multiple second winding assemblies 250, so as to improve the winding efficiency of the diaphragms. Since each first winding assembly 230 is arranged staggeredly in the axial direction of the core 210 with a second winding assembly 250, thus, interference between two adjacent first winding assemblies 230 or two adjacent second winding assemblies 250 can be avoided.

[0057] Specifically, continue to refer to Figure 1 As shown, in the axial direction of the first core 240, a detection component 310 is arranged at a preset position at both axial ends of each first core 240. Thus, the position of each diaphragm on the first core 240 can be detected by the multiple detection components 310, so as to improve the accuracy of the placement position of the diaphragm. In the axial direction of the second core 260, a detection component 310 is arranged at a preset position at both axial ends of each second core 260. Thus, the position of each diaphragm on the second core 260 can be detected by the multiple detection components 310, so as to improve the accuracy of the placement position of the diaphragm.

[0058] Continue to refer to Figure 1As shown, there are two sliding components 320. The two sliding components 320 are arranged at intervals along the radial direction of the core 210. One of the sliding components 320 is arranged at one end of the first core 240 along its radial direction away from the second core 260, and the other sliding component 320 is arranged at one end of the second core 260 along its radial direction away from the first core 240.

[0059] In this embodiment, since one of the sliding components 320 is arranged at one end of the first core 240 along its radial direction away from the second core 260, and the other sliding component 320 is arranged at one end of the second core 260 along its radial direction away from the first core 240, thus, it can be ensured that both the first winding component 230 and the second winding component 250 are located between the two sliding components 320. And the guiding member 321 of one of the sliding components 320 is arranged close to the first winding component 230, and the guiding member 321 of the other sliding component 320 is arranged close to the second winding component 250, so that the detecting component 310 for detecting the diaphragm on the first core 240 can slide on the guiding member 321 of one of the sliding components 320, and at the same time, the detecting component 310 for detecting the diaphragm on the second core 260 can slide on the guiding member 321 of the other sliding component 320, so as to realize the detection of the installation positions of the diaphragms on all the cores 210.

[0060] Specifically, continue to refer to Figure 1 As shown, in the guiding member 321 arranged close to the first core 240, each first core 240 is located within the range of the guiding member 321. Thus, it can be ensured that each first core 240 can be located within the moving range of each detecting component 310 along the axial direction of the first core 240, so that when the number, size and position of the first cores 240 change, there is a detecting component 310 at the preset position of each first core 240. In the guiding member 321 arranged close to the second core 260, each second core 260 is located within the range of the guiding member 321. Thus, it can be ensured that each second core 260 can be located within the moving range of each detecting component 310 along the axial direction of the second core 260, so that when the number, size and position of the second cores 260 change, there is a detecting component 310 at the preset position of each second core 260, so as to improve the applicable range of the above-mentioned diaphragm slitting equipment.
