Description

Technical Field

[0001] This application relates to the technical field of diaphragm preparation devices, and more particularly, to a guiding edge device and a guiding edge system. Background Art

[0002] In the process of preparing wet diaphragms, a high-boiling-point and low-volatility solvent (such as paraffin oil) is used as a pore-forming agent. During the transverse stretching of the diaphragm, a stretching device is usually used to clamp the edge of the diaphragm.

[0003] When using the current stretching device to stretch the diaphragm, the position of the edge of the diaphragm is likely to shift during the stretching process. However, when the current stretching device detects the position of the edge of the diaphragm and makes adjustments, the surface of the stretching device will contact the diaphragm and accumulate the pore-forming agent (paraffin oil) on the surface of the stretching device. The accumulated pore-forming agent (paraffin oil) will be blown by the current stretching device onto the surface of the diaphragm, affecting the quality of the diaphragm. Summary of the Utility Model

[0004] Based on the above deficiencies, this application provides a guiding edge device and a guiding edge system to improve the problem of poor diaphragm quality in related technologies.

[0005] This application is implemented as follows:

[0006] In a first aspect, an example of this application provides a guiding edge device, including a body and a laser sensor; the body is provided with a first guiding edge part and a second guiding edge part, and a gap for the edge of the diaphragm to pass through is formed between the first guiding edge part and the second guiding edge part; a liquid accumulation groove is arranged on one side of the first guiding edge part facing the second guiding edge part, and the liquid accumulation groove is used to receive the excess pore-forming agent of the edge of the diaphragm; the laser sensor includes a transmitter and a receiver, the transmitter is arranged on one of the first guiding edge part and the second guiding edge part, the receiver is arranged on the other of the first guiding edge part and the second guiding edge part, and the transmitter and the receiver are arranged opposite to each other; the laser sensor is used to detect whether the edge of the diaphragm passes between the transmitter and the receiver.

[0007] In the above implementation process, a gap is arranged between the first guiding edge part and the second guiding edge part of the guiding edge device body, and a transmitter and a receiver are respectively arranged at positions corresponding to both sides of the gap on the first guiding edge part and the second guiding edge part. When the edge of the diaphragm penetrates into the gap and extends between the transmitter and the receiver, the edge of the diaphragm will block the laser emitted by the transmitter, resulting in the receiver being unable to receive. When the edge of the diaphragm does not penetrate into the gap between the transmitter and the receiver, the receiver can receive the laser signal emitted by the transmitter. Therefore, by using the laser sensor, the relative position between the edge of the diaphragm and the guiding edge device can be judged in real time, so as to adjust the position of the edge of the diaphragm according to the position signal obtained by the laser sensor and improve the quality of the diaphragm.

[0008] When the edge of the separator penetrates into the gap of the edge guide for edge guiding, the pore former at the edge of the separator is likely to adhere to the first edge guiding part. Over time, oil accumulation is likely to form at the first edge guiding part, which is likely to cause defects on the surface of the separator. In the edge guide provided in this example, a liquid accumulation groove is provided on the side of the first edge guiding part facing the second edge guiding part. The liquid accumulation groove can receive the accumulated oil, reducing the probability of defects formed on the surface of the separator due to the accumulated oil, so as to further improve the quality of the separator.

[0009] Combined with the first aspect, in an optional implementation manner, the laser sensor includes a plurality of groups of corresponding transmitters and receivers, and the plurality of groups of transmitters and receivers are arranged at intervals perpendicular to the moving direction of the separator.

[0010] In the above implementation process, by arranging a plurality of groups of spaced transmitters and receivers at the edge guide, the laser sensor can sense which group of transmitters and receivers the edge of the separator is specifically located between, and can more accurately judge the position of the edge of the separator.

[0011] Combined with the first aspect, in an optional implementation manner, a suction pipe is provided on the first edge guiding part, and the suction pipe is communicated with the liquid accumulation groove for pumping out the accumulated oil in the liquid accumulation groove.

[0012] In the above implementation process, by providing a suction pipe communicated with the liquid accumulation groove on the first edge guiding part, the accumulated oil in the liquid accumulation groove can be pumped out, further reducing the probability of the accumulated oil contaminating the separator.

[0013] Combined with the first aspect, in an optional implementation manner, the receiver is arranged in the liquid accumulation groove, and the transmitter is arranged on the second edge guiding part.

[0014] In the above implementation process, by arranging the receiver in the liquid accumulation groove, the probability of the receiver protruding beyond the first edge guiding part and damaging the separator can be reduced.

[0015] Combined with the first aspect, in an optional implementation manner, an installation groove is provided on the side of the second edge guiding part facing the first edge guiding part, and the transmitter is arranged in the installation groove.

[0016] In the above implementation process, by providing an installation groove on the side of the second edge guiding part facing the first edge guiding part and arranging the transmitter in the installation groove, the influence of the transmitter on the separator can be reduced.

[0017] Combined with the first aspect, in an optional implementation manner, the transmitter is fixed to the top wall of the installation groove, and a blowing pipe is further provided on the second edge guiding part. The blowing pipe is obliquely downwardly arranged on the side wall of the installation groove for blowing off the oil stain attached to the receiver.

[0018] In the above implementation process, the emitter is arranged on the top wall of the installation groove, and a blow pipe inclined downward is arranged on the side wall of the installation groove. The blow pipe can be used to blow downward obliquely on the receiver below the emitter to blow off oil stains such as pore-forming agents attached to the receiver, ensuring the detection accuracy of the laser sensor.

[0019] Combined with the first aspect, in an optional implementation manner, the surface of the second guiding edge portion on the side facing the first guiding edge portion is an inclined surface or a curved surface.

[0020] Combined with the first aspect, in an optional implementation manner, the second guiding edge portion is in an inverted triangular shape or a cylindrical shape.

[0021] In the above implementation process, the surface of the second guiding edge portion on the side facing the first guiding edge portion is set as an inclined surface or a curved surface. During the guiding edge process, it is not easy for oil to accumulate on the inclined surface or the curved surface, thereby reducing the probability of oil dripping from the second guiding edge portion onto the diaphragm and improving the quality of the diaphragm.

[0022] In the second aspect, an example of the present application provides a guiding edge system, including the guiding edge device provided in the first aspect.

[0023] In the above implementation process, the guiding edge device provided in the first aspect is arranged in the guiding edge system. The guiding edge device can detect the position of the edge of the diaphragm, so as to facilitate the guiding edge system to adjust the position of the edge of the diaphragm.

[0024] Combined with the second aspect, in an optional implementation manner, the guiding edge system further includes an adjustment mechanism; the adjustment mechanism includes a controller, a moving member, and a fixture; the fixture is used to clamp the edge of the diaphragm; the fixture is connected to the moving member, and the laser sensor is signal-connected to the controller; the laser sensor detects the position of the edge of the diaphragm and sends a signal to the controller, and the controller controls the moving member to drive the fixture to move.

[0025] When guiding the edge using the above guiding edge system, the edge of the diaphragm is clamped at the fixture, and the edge of the diaphragm passes through the gap of the guiding edge device. When the laser sensor in the guiding edge device detects that the position of the edge of the diaphragm is offset relative to the guiding edge device, the laser sensor sends a signal to the controller. The controller receives the signal and controls the moving member to drive the fixture to move, thereby adjusting the position of the edge of the diaphragm. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Hereinafter, embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and thus are only examples and cannot be used to limit the protection scope of the present application.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0038] In the process of preparing the diaphragm 100, it is usually necessary to perform biaxial stretching on the diaphragm 100. During the transverse stretching of the diaphragm 100, it is usually necessary to use a fixture to clamp the edge of the diaphragm 100.

[0039] When using the current device to stretch the diaphragm 100, the position of the edge of the diaphragm 100 is likely to shift, and it is impossible to detect the position of the edge of the diaphragm 100 and make adjustments. If the position of the edge of the diaphragm 100 shifts, it will affect the quality of the stretched diaphragm 100.

[0040] To improve the quality of the diaphragm 100, the embodiments of the present application provide a guiding edge system 1 and a guiding edge device 10. To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0041] Please refer to Figure 1 , the guiding edge system 1 provided by the example of the present application includes a guiding edge device 10 and an adjusting mechanism 20.

[0042] Please refer to Figure 2 , the guiding edge device 10 includes a body 11 and a laser sensor 12.

[0043] Among them, please continue to refer to Figure 2 and Figure 3 , the body 11 is provided with a first guiding edge portion 111 and a second guiding edge portion 112, and a gap 113 for the edge of the diaphragm 100 to pass through is formed between the first guiding edge portion 111 and the second guiding edge portion 112.

[0044] Among them, please refer to Figure 3 and Figure 4 , the laser sensor 12 includes a transmitter 121 and a receiver 122. The transmitter 121 is disposed on one of the first guiding edge portion 111 and the second guiding edge portion 112, and the receiver 122 is disposed on the other of the first guiding edge portion 111 and the second guiding edge portion 112. The transmitter 121 and the receiver 122 are disposed opposite to each other. The laser sensor 12 is used to detect whether the edge of the diaphragm 100 passes between the transmitter 121 and the receiver 122.

[0045] Since the transmitter 121 and the receiver 122 are relatively spaced apart, the receiver 122 can receive the laser emitted by the transmitter 121 and generate a first signal. If the laser emitted by the transmitter 121 is blocked, causing the receiver 122 to be unable to receive the laser emitted by the transmitter 121, the laser sensor 12 will generate a second signal different from the first signal.

[0046] When using the above-mentioned edge guide 10 to guide the edge of the diaphragm 100, when the receiver 122 in the laser sensor 12 receives the laser emitted by the transmitter 121 and generates a first signal, it means that the edge of the diaphragm 100 does not extend into the gap 113 of the edge guide 10 between the transmitter 121 and the receiver 122. When the reception of the laser signal by the laser receiver 122 is interrupted, the laser sensor 12 generates a second signal, indicating that the edge of the diaphragm 100 extends into the gap 113 between the transmitter 121 and the receiver 122. Therefore, by using the above-mentioned edge guide 10, the position of the edge of the diaphragm 100 relative to the laser sensor 12 can be detected.

[0047] If the target position of the edge of the diaphragm 100 is set to the side of the laser sensor 12 away from the diaphragm 100, such as Figure 2 in an edge guide on the left, the target position is on the left side of the laser sensor 12, that is, the edge of the diaphragm 100 needs to pass through the transmitter 121 and the receiver 122. When the laser sensor 12 generates a first signal, it means that the position of the edge of the diaphragm 100 is shifted to the right relative to the target position, and the position of the diaphragm 100 needs to be adjusted according to the first signal so that the edge of the diaphragm 100 moves between the transmitter 121 and the receiver 122.

[0048] If the target position of the edge of the diaphragm 100 is set to the side of the laser sensor facing the diaphragm 100, such as Figure 2 in an edge guide on the left, the target position is on the right side of the laser sensor 12, that is, the edge of the diaphragm 100 cannot extend between the transmitter 121 and the receiver 122. When the receiver 122 of the laser sensor 12 interrupts the reception of the signal and generates a second signal, it means that the edge of the diaphragm 100 is shifted to the left relative to the target position, and the position of the diaphragm 100 needs to be adjusted according to the second signal so that the edge of the diaphragm 100 moves to the right from between the transmitter 121 and the receiver 122 outside the laser sensor 12.

[0049] If other sensors are used to detect the position of the edge of the diaphragm 100, for example, a pneumatic sensor, the blowing probe of the pneumatic sensor will blow air into the induction receiving port. During the detection process, oil substances such as pore-forming agents at the diaphragm 100 will be blown to form accumulated oil at the body 11, or the accumulated oil at the body 11 will be blown back to the film surface again, causing pollution to the diaphragm 100. In this example, a laser sensor 12 is used to detect the position of the edge of the diaphragm 100. The laser sensor 12 will not blow the accumulated oil to cause pollution to the diaphragm 100 during the detection process, and can improve the quality of the diaphragm 100.

[0050] Further, in order to detect the position of the edge of the diaphragm 100 more accurately, in a possible embodiment, the laser sensor 12 includes a plurality of groups of corresponding transmitters 121 and receivers 122, and the plurality of groups of transmitters 121 and receivers 122 are arranged at intervals along the direction perpendicular to the movement direction of the diaphragm 100.

[0051] Exemplarily, please refer to Figure 4 , the laser sensor 12 includes four groups of transmitters 121 and receivers 122 arranged at intervals.

[0052] As Figure 4 shown in, from left to right, the installation positions of the four groups of transmitters 121 and receivers 122 can be marked as the first position 01, the second position 02, the third position 03, and the fourth position 04.

[0053] If the receiver 122 at the fourth position 04 receives the laser signal, it means that the edge position of the diaphragm 100 is on the right side of the laser sensor 12. If the receiver 122 at the fourth position 04 does not receive the laser signal, but the receiver 122 at the third position 03 receives the laser signal, it means that the edge position of the diaphragm 100 is between the third position 03 and the fourth position 04. And so on, the position of the edge of the diaphragm 100 can be determined more accurately.

[0054] In a possible embodiment, the target position of the edge of the diaphragm 100 can be set between the second position 02 and the third position 03.

[0055] If the receiver 122 at the third position 03 receives the laser signal, it means that the position of the edge of the diaphragm 100 is shifted to the right relative to the target position and is not located between the second position 02 and the third position 03. In this case, the diaphragm 100 needs to be moved leftward by a certain distance. Moreover, the approximate distance for the diaphragm 100 to move leftward can be determined according to the reception condition of the receiver 122 at the fourth position 04. For example, the distance between the third position 03 and the fourth position 04 is the first length. When the receiver 122 at the fourth position 04 receives the laser signal, it means that the position of the edge of the diaphragm 100 is between the third position 03 and the fourth position 04. The diaphragm 100 can be moved leftward by the first length to make the position of the edge of the diaphragm 100 between the second position 02 and the third position 03.

[0056] If the receiver 122 at the second position 02 does not receive the laser signal, it means that the position of the edge of the diaphragm 100 is shifted to the left relative to the target position, and the diaphragm 100 needs to be moved rightward by a certain distance. Further, if the receiver 122 at the first position 01 receives the laser signal, it means that the position of the edge of the diaphragm 100 is between the first position 01 and the second position 02. If the distance between the first position 01 and the second position 02 is the second length, the diaphragm 100 can be moved rightward by the second length to make the position of the edge of the diaphragm 100 between the second position 02 and the third position 03.

[0057] Generally, the diaphragm 100 is a wet film, and a pore-forming agent, such as paraffin oil, remains on the surface of the diaphragm 100. The edge of the diaphragm 100 is guided by the edge guide 10. When the edge of the diaphragm 100 extends into the gap 113, the pore-forming agent at the diaphragm 100 is likely to adhere to the first edge guiding portion 111. Over time, oil accumulation is likely to form at the first edge guiding portion 111. Since the diaphragm 100 vibrates up and down, during the edge guiding process, the diaphragm 100 may come into contact with the accumulated oil at the first edge guiding portion 111, thereby contaminating the diaphragm 100.

[0058] Therefore, to reduce the probability of contamination of the diaphragm 100, please continue to refer to Figure 3 In the edge guide 10 provided in the exemplary embodiment of the present application, a liquid accumulation groove 114 is provided on the side of the first edge guiding portion 111 facing the second edge guiding portion 112. The liquid accumulation groove 114 is used to receive the excess pore-forming agent at the edge of the diaphragm 100.

[0059] Exemplarily, the first edge guiding portion 111 is located below the second edge guiding portion 112.

[0060] Since the liquid accumulation groove 114 has a certain depth, even if the diaphragm 100 vibrates up and down during the edge guiding process, it will not extend into the interior of the liquid accumulation groove 114 and will not come into contact with the accumulated oil in the liquid accumulation groove 114, thereby reducing the probability of forming defects on the surface of the diaphragm 100.

[0061] Further, in order to facilitate the discharge of the accumulated oil in the liquid accumulation tank 114, in a possible embodiment, please continue to refer to Figure 3 A suction pipe 115 connected to the liquid accumulation groove 114 can be provided at the first guide edge portion 111. When there is a lot of accumulated oil in the liquid accumulation groove 114, the suction pipe 115 can be used to extract the accumulated oil in the liquid accumulation groove 114.

[0062] Furthermore, a transfer tank (not shown in the figure) may be provided, and the suction pipe 115 draws the accumulated oil in the liquid accumulation tank 114 into the transfer tank.

[0063] During the edge guiding process, due to the shaking of the diaphragm 100, it may contact the bottom surface of the second edge guiding portion 112, forming oil stains. As the edge guiding progresses, these oil stains gradually accumulate and may form oil drops that fall onto the diaphragm 100 below the second edge guiding portion 112, causing contamination of the diaphragm 100.

[0064] If the bottom surface of the second guide edge portion 112 is a plane, for example, the second guide edge portion 112 is set to a rectangular parallelepiped structure, the diaphragm 100 will be in surface contact with the second guide edge portion 112 of the rectangular parallelepiped, the contact area is increased, and oil stains are easily attached.

[0065] Therefore, in order to further reduce the probability of contamination of the diaphragm 100 , in some possible embodiments, the surface on the bottom side of the second guide edge portion 112 may be set to be a slope.

[0066] Since the bottom surface of the second guide edge portion 112 is a slope, even when the diaphragm 100 vibrates and contacts the second guide edge portion 112, the contact area between the diaphragm 100 and the second guide edge portion 112 is small, similar to line contact, thereby reducing the probability of oil stains adhering to the bottom surface of the second guide edge portion 112.

[0067] Exemplarily, the second guide edge portion 112 may be configured to be an inverted triangle or a cylinder.

[0068] For example, see Figure 5 , the second guide edge portion 112 can be set to be cylindrical.

[0069] Furthermore, the present application does not limit the specific shape of the first guide edge portion 111. In a possible embodiment, please continue to refer to Figure 5 , the first guide edge portion 111 can be set to a rectangular parallelepiped structure.

[0070] Exemplarily, the first guide edge portion 111 is a rectangular structure, and the second guide edge portion 112 is a cylindrical structure. Pads are provided at the ends of the rectangular structure and the cylindrical structure facing away from the diaphragm 100 to form a gap 113 between the end of the rectangular structure facing the diaphragm 100 and the end of the cylindrical structure facing the diaphragm 100.

[0071] Further, the present application does not limit the specific installation positions of the transmitter 121 and the receiver 122 in the laser sensor 12. In a possible embodiment, the receiver 122 can be disposed on the second guiding edge portion 112, and the transmitter 121 can be disposed on the first guiding edge portion 111.

[0072] Or, in some other possible embodiments, please continue to refer to Figure 4 , the receiver 122 can be disposed on the first guiding edge portion 111, and the transmitter 121 can be disposed on the second guiding edge portion 112.

[0073] Further, in some possible embodiments, please continue to refer to Figure 4 , the receiver 122 can be disposed in the liquid accumulation groove 114 of the first guiding edge portion 111, so as to prevent the top end of the receiver 122 from protruding out of the first guiding edge portion 111 and contacting the diaphragm 100, thereby avoiding damage to the diaphragm 100 and improving the quality of the diaphragm 100.

[0074] Further, please continue to refer to Figure 4 , an installation groove 116 can be provided on the side of the second guiding edge portion 112 facing the first guiding edge portion 111, and the transmitter 121 can be disposed in the installation groove 116.

[0075] During the guiding edge process, when the edge of the diaphragm 100 penetrates between the transmitter 121 and the receiver 122, the pore-forming agent at the diaphragm 100 may adhere to the receiver 122, affecting the detection efficiency.

[0076] Therefore, in order to further improve the detection efficiency of the laser sensor 12, in some possible embodiments, an air blowing pipe 117 can be provided at the second guiding edge portion 112, and the air blowing pipe 117 blows air downward to blow off the oil stain adhering to the receiver 122.

[0077] Further, in some possible embodiments, a plurality of transmitters 121 can be spaced apart and disposed on the top wall of the installation groove 116, and a plurality of air blowing pipes 117 can be sequentially disposed on the top wall of the installation groove 116 between two transmitters 121, and the air blowing pipes 117 blow air vertically downward.

[0078] However, since the receiver 122 is located directly below the transmitter 121, when the air blowing pipes 117 between the transmitters 121 blow air downward, the air will blow to the position between two receivers 122, resulting in low cleaning efficiency of the receiver 122.

[0079] In order to further improve the cleaning efficiency of the receiver 122, in some possible embodiments, please continue to refer to Figure 4, at two side walls of the installation groove 116 along the direction of the emitter 121, a plurality of air blowing pipes 117 are vertically arranged at intervals. The air outlets of the plurality of air blowing pipes 117 are arranged obliquely downward, and the air blowing ports of the plurality of air blowing pipes 117 face the plurality of receivers 122 one by one, so that the air blowing pipes 117 can blow air obliquely downward to blow off the oil stains attached to the receivers 122. That is, the air blowing ports of the air blowing pipes 117 are at two side walls of the installation groove 116 perpendicular to the moving direction of the diaphragm 100.

[0080] Further, in some possible embodiments, a plurality of air blowing pipes 117 corresponding to the receivers 122 one by one can be arranged at two side walls of the installation groove 116 along the moving direction of the diaphragm 100.

[0081] Further, the air blowing pipe 117 includes a main pipe, a plurality of first branch pipes and a plurality of second branch pipes. The plurality of first branch pipes are arranged at two side walls of the installation groove 116 perpendicular to the moving direction of the diaphragm 100, the plurality of second branch pipes are arranged at two side walls of the installation groove 116 along the moving direction of the diaphragm 100, and the first branch pipes and the second branch pipes can be selectively connected to the main pipe.

[0082] Further, a first switch valve can be arranged at the first branch pipe, and a second switch valve can be arranged at the second branch pipe.

[0083] When purging is required along the direction perpendicular to the moving direction of the diaphragm 100, the first switch valve can be opened and the second switch valve can be closed, so that the air flow in the main pipe can be blown out through the first branch pipe. When purging is required along the moving direction of the diaphragm 100, the second switch valve can be opened and the first switch valve can be closed, so that the air flow in the main pipe can be blown out through the second branch pipe. When multi-directional simultaneous purging is required along the moving direction of the diaphragm 100 and along the direction perpendicular to the moving direction of the diaphragm 100, the first switch valve and the second switch valve can be opened, so that the air flow in the main pipe can be blown out through the first branch pipe and the second branch pipe.

[0084] When the edge guide 10 detects that the edge position of the diaphragm 100 is deviated, in order to facilitate the adjustment of the position of the diaphragm 100, in some possible embodiments, please continue to refer to Figure 1 , the edge guiding system 1 provided by the example of the present application is further provided with an adjusting mechanism 20.

[0085] Exemplarily, the adjusting mechanism 20 includes a controller 21, a moving member 22 and a fixture (not shown in the figure). The fixture is used to clamp the edge of the diaphragm 100. The fixture is connected to the moving member 22, and the laser sensor 12 is signal-connected to the controller 21. The laser sensor 12 detects the position of the edge of the diaphragm 100 and sends a signal to the controller 21, and the controller 21 controls the moving member 22 to drive the fixture to move to adjust the position of the edge of the diaphragm 100.

[0086] Exemplarily, the laser sensor 12 is wired to the controller 21.
