[0033] The present utility model provides a material stripping device 100, which is applicable to stripping the material on the tape. Among them, the tape includes a protective film and the material provided on the protective film. By separating the material from the protective film, it is convenient to perform functional tests on the subsequent structure of the material. The material can be a microphone, an electronic component, or other parts with micropores. Hereinafter, for the convenience of description, taking the material as a microphone as an example, the specific structure of the material stripping device 100 will be described.

[0034] Specifically, please refer to Figures 1 to 2, in this embodiment, the material stripping device 100 includes a machine frame 1, a tape conveying assembly 2, a stripping mechanism (not shown in the drawings), and a detection assembly 3; the tape conveying assembly 2 includes a tape unwinding wheel 21 rotatably arranged on the machine frame 1, a platform structure 22, and a protective film winding wheel rotatably arranged on the machine frame 1. The tape unwinding wheel 21 is used for winding the tape thereon, and the protective film winding wheel is used for recovering the protective film after the product is stripped. A stripping station is provided on the platform structure 22; the stripping mechanism is arranged on the machine frame 1 and is used for stripping the material on the tape at the stripping station; the detection assembly 3 is arranged on the machine frame 1; wherein, the tape unwound from the tape unwinding wheel 21 can be conveyed towards the platform structure 22, stripped by the stripping mechanism, and then wound into the protective film winding wheel. The detection area of the detection assembly 3 is set corresponding to the protective film conveying path between the stripping station and the protective film winding wheel.

[0035] In this embodiment, the tape conveying assembly 2 can be used to unwind and convey the rolled tape to the platform structure 22, so that the stripping mechanism can strip the material from the tape; moreover, the detection assembly 3 can detect whether there is material on the tape to ensure that the material is completely stripped from the tape; moreover, the detection area of the detection assembly 3 is set corresponding to the protective film conveying path between the stripping station and the protective film winding wheel. The detection assembly 3 can detect whether the material on the tape is completely stripped, so as to ensure that the tape can be conveyed again after the material is stripped, so as to ensure that each material can be stripped without missing stripping, making the stripping effect of the material better and the stripping efficiency higher.

[0036] Preferably, the stripping station can be arranged at the conveying end of the platform structure 22, and the detection assembly 3 is arranged corresponding to the conveying end of the platform structure 22. When the microphone is removed by the stripping mechanism at the conveying end of the platform structure 22 and the tape continues to be conveyed, the protective film of the stripped microphone can be sucked and moved to the detection area of the detection assembly 3, so that the detection assembly 3 can quickly detect whether the microphone has been removed. If the microphone has been stripped of the protective film, the tape can be controlled to continue to be conveyed, so that the next tape containing the microphone can be moved to the stripping station and wait for the stripping mechanism to pick and strip the microphone. If the microphone is not removed from the protective film, the tape is controlled to pause until the stripping mechanism removes the microphone, which can effectively avoid the phenomenon of missing stripping.

[0037] Among them, in combination with Figures 1 to 3As shown, the platform structure 22 includes a platform support plate 221 and a pressing plate 224. The platform support plate 221 is arranged on the frame 1 and is generally arranged in a flat plate shape. It should be noted that when the material stripping device 100 is working normally, the platform support plate 221 is arranged in the horizontal direction. A guiding groove 222 extending along the transverse direction of the frame 1 is provided on the platform support plate 221. Here, the transverse direction can refer to a direction on the horizontal plane, and the longitudinal direction is perpendicular to the transverse direction on the horizontal plane. Among them, the transverse direction can refer to the front-back direction of the frame 1, and the longitudinal direction can refer to the left-right direction of the frame 1. In the present invention, unless otherwise specified, the description of the orientation can be referred to this as a reference. The pressing plate 224 is arranged on the platform support plate 221 and at least partially extends into the guiding groove 222. A tape passing gap is formed between the pressing plate 224 and the bottom of the guiding groove 222. Both ends of the guiding groove 222 in the transverse direction of the frame 1 are open. The tape can penetrate into the guiding groove 222 from one end in the transverse direction of the guiding groove 222 and penetrate out from the other end in the transverse direction of the guiding groove 222. The tape can be pressed flat in the guiding groove 222 through the pressing plate 224 to prevent the tape from warping, so that the stripping mechanism can pick up the material better. Preferably, the width of the guiding groove 222 is adapted to the width of the tape, which can better ensure the position of the tape on the platform support plate 221, so that the stripping mechanism can pick up the material better in alignment.

[0038] Since the sizes of different tapes are different, the widths of the corresponding guiding grooves 222 will also be different. Preferably, one side wall of the guiding groove 222 in the longitudinal direction of the frame 1 is open; the platform structure 22 further includes an adjusting plate 225. The adjusting plate 225 is arranged at the open place to jointly form a tape passing gap with the other side wall of the guiding groove 222 in the longitudinal direction of the frame 1. The width of the tape passing gap in the longitudinal direction is adapted to the width of the tape; among them, the adjusting plate 225 is movably arranged to adjust the width of the tape passing gap in the longitudinal direction of the frame 1, that is, to adjust the width of the guiding groove 222, so that the guiding groove 222 can better adapt to the stripping requirements of tapes with different widths.

[0039] Furthermore, there are two pressing plates 224. The two pressing plates 224 are arranged oppositely in the longitudinal direction of the frame 1 on both sides of the guiding groove 222, so as to respectively press both sides of the tape in its width direction, better ensuring the flatness of the tape. Moreover, one of the pressing plates 224 is arranged on the adjusting plate 225. After the width of the tape changes, the width of the guiding groove 222 can be adjusted by moving the adjusting plate 225. Furthermore, one pressing plate 224 remains unchanged, and one pressing plate 224 can move together with the adjusting plate 225. While better centering the tape, the two pressing plates 224 can better press on the tape, and there is no need to adjust the pressing plates 224 separately, making the operation more convenient.

[0040] Preferably, the pressing plate 224 is disposed near the conveying end of the platform support plate 221 to ensure the flatness of the strip at the peeling station, which is more convenient for the peeling mechanism to pick up the material.

[0041] In another embodiment, when there are two pressing plates 224, two adjusting plates 225 can also be provided. The two pressing plates 224 and the two adjusting plates 225 are arranged in one-to-one correspondence, so that the adjustment range of the guiding groove 222 is larger. When the strip is aligned with the central axis of the guiding groove 222, this adjustment method can better ensure the centering of the strip.

[0042] It can be understood that there are many ways for the adjusting plate 225 to move relative to the platform support plate 221. For example, the adjusting plate 225 can be slidably arranged on the platform support plate 221 through an adjusting screw. By rotating the adjusting screw, the adjusting plate 225 can move longitudinally along the platform support plate 221. Or, the adjusting plate 225 and the platform support plate 221 are attracted and fixed to each other. The first magnetic attraction part on the adjusting plate 225 is magnetically attracted and matched with a plurality of second magnetic attraction parts on the platform support plate 221, so as to adjust the position of the adjusting plate 225.

[0043] Preferably, as Figure 3 shown in, a long hole 226 is provided on one of the adjusting plate 225 and the platform support plate 221, and a plurality of mounting holes 223 are provided on the other. The material peeling device 100 further includes a connecting piece, and the connecting piece passes through the long hole 226 and the corresponding mounting holes 223 to fix the adjusting plate 225 at multiple positions on the platform support plate 221. Among them, the long hole 226 extends longitudinally along the frame 1. The connecting piece can be set as a screw, a bolt or a pin, etc., so that the fixing between the adjusting plate 225 and the platform support plate 221 is more reliable and convenient for adjustment.

[0044] Moreover, the strip conveying assembly 2 further includes a plurality of unwind guiding wheels 228. The rotating shafts of the plurality of unwind guiding wheels 228 are parallel to the rotating shaft of the strip unwind wheel 21, and in the conveying direction of the strip, the unwind guiding wheel 228 at the conveying end is disposed near the conveying start end of the platform structure 22, so that the strip can be better conveyed onto the platform structure 22 and the strip is ensured to be in a taut state.

[0045] Preferably, each unwinding guide wheel 228 includes an unwinding shaft body 2281 and two limiting wheels 2282 provided on the unwinding shaft body 2281. The two limiting wheels 2282 are arranged at intervals to form a receiving gap for the feeding tape to wind around. The receiving gap is adapted to the width of the tape, ensuring that the tape does not shift during transmission, making the tape transmission alignment more accurate and thus more convenient for material picking. Moreover, at least one of the two limiting wheels 2282 is movably arranged. By moving the limiting wheel 2282, the size of the receiving gap can be adjusted. After the width of the tape changes, the position of the limiting wheel 2282 can be adjusted accordingly, so that the material peeling device 100 can better adapt to the use requirements of tapes of different sizes.

[0046] In addition, the material peeling device 100 further includes a driving structure 4. The driving structure 4 is connected to the protective film winding wheel and is used to drive the protective film winding wheel to rotate. Moreover, a plurality of winding guide wheels 227 are arranged between the end of the platform support plate 221 and the protective film winding wheel. Through the plurality of winding guide wheels 227, the protective film can be in a taut state, and better winding can be achieved.

[0047] For the material peeling mechanism, the material peeling mechanism is used to pick up materials (such as microphones) on the tape. The material peeling mechanism may include a robotic arm and a picking head provided at the end of the robotic arm. Through the multi-degree-of-freedom movement of the robotic arm, the picking head can flexibly pick up materials on the tape. The picking head can be set as a vacuum suction head, a clamping jaw or a magnetic attraction block, etc. Different picking heads can be replaced according to different materials.

[0048] Among them, the detection component 3 can be set as an induction optical fiber, which can better obtain the situation of the materials on the tape and the detection structure is more accurate. Of course, the material peeling device 100 may further include a controller. The controller is electrically connected to the detection component 3 and the driving structure 4. By obtaining the situation of the materials on the tape through the detection component 3 and transmitting the detection signal to the controller, the controller can judge whether there are materials on the tape according to the detection signal, so as to control the driving structure 4 to work, making the work of the entire material peeling device 100 more intelligent.

[0049] When the material peeling device 100 starts to work, the driving structure 4 can be started to drive the protective film winding wheel to rotate. Thus, under the action of the tightening force, the protective film pulls the tape to move, so that the tape can be unrolled from the tape unwinding wheel 21, enters the guiding groove 222 of the platform support plate 221 after passing through a plurality of unwinding guide wheels, and after the tape is transferred to the peeling station, it can be temporarily separated from the driving structure 4, so that the tape pauses at the peeling station to wait for the material peeling mechanism to pick up the material. After the material peeling mechanism finishes picking up the material and the detection component 3 detects that the material has been taken out, the driving structure 4 starts to work again. Repeating the work like this can achieve the peeling of the material and the protective film, with higher work efficiency and better peeling effect.

[0050] The present utility model also provides a microphone processing production line, which includes the above-mentioned material stripping device 100, so that foreign matters are not easily introduced during the processing of the microphone, and the yield rate of the microphone is higher. Moreover, the microphone processing production line may include multiple sets of material stripping devices 100, and two of the multiple sets of material stripping devices 100 can share a stripping mechanism, thereby achieving higher stripping efficiency.

[0051] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structures made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
