Abstract
Description
Technical Field
[0001] This utility model relates to the field of receiver technology, specifically to a diaphragm separation device. Background Technology
[0002] A receiver is an electroacoustic device that converts audio electrical signals into sound signals without sound leakage. It is widely used in communication terminal equipment such as mobile phones, landline phones, and headsets to achieve audio output. A receiver typically contains a thin, highly sensitive diaphragm that responds to the incoming electrical signal, generating minute vibrations and converting these vibrations into sound waves, thus achieving the receiver's electroacoustic conversion.
[0003] However, during the production of receivers, due to the requirements of product performance, the overall quality of the diaphragm needs to be thin, soft and easily vibrated. Therefore, under the influence of static electricity and other factors, the diaphragm is prone to sticking together, making it difficult to pick up only one diaphragm at a time. It often requires manual assistance to separate the sticking diaphragms, which leads to low production efficiency. In addition, the diaphragm is soft and thin, making manual separation difficult and easy to damage the diaphragm. Utility Model Content
[0004] The purpose of this invention is to provide a diaphragm separation device, which aims to improve the problem that existing receivers are prone to diaphragm adhesion during production, making manual separation difficult and resulting in low production efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A membrane separation device, comprising:
[0007] A material storage mechanism includes a loading platform, a storage bin, a screening plate, and a mounting frame for placing the storage bin. The mounting frame is disposed on the loading platform, and the screening plate is disposed on the top surface of the storage bin. At least one storage trough is provided inside the storage bin, and the screening plate has a screening thread that aligns with the opening of the storage trough.
[0008] The material handling mechanism includes a support frame that elevates itself, a suction cup unit, a first drive unit that drives the suction cup unit to move up and down, and a second drive unit that drives the first drive unit to move horizontally toward or away from the material storage mechanism.
[0009] Preferably, there are two placement racks, which are symmetrically arranged on the loading platform;
[0010] A rotary power unit that drives the material loading platform to rotate is provided in the middle of the loading platform.
[0011] Preferably, it also includes a monitoring sensor, which includes a sensor receiver and a sensor transmitter, the sensor receiver being located on one side of the storage bin and the sensor transmitter being located on the other side of the storage bin;
[0012] The top of the storage box is provided with a monitoring through hole that runs through both sides of the storage box and through the storage trough, and the monitoring beam of the monitoring sensor is aligned with the monitoring through hole.
[0013] Preferably, the placement rack includes two symmetrically arranged slots, and the bottom of the slots is provided with a placement block for supporting the storage box.
[0014] Preferably, it also includes a clamping member, which is disposed on the loading platform and presses against the storage bin.
[0015] Preferably, it also includes a lifting mechanism located directly below the placement frame. The lifting mechanism includes at least one lifting member and a lifting power unit for driving the lifting member to move up and down.
[0016] The bottom of the storage tank is provided with a lifting hole that is aligned with the lifting component.
[0017] Preferably, the screening plate includes a first screening plate and a second screening plate, wherein the first screening plate and the second screening plate are joined together to form the screening thread.
[0018] The top surface of the storage box is provided with a plurality of first mounting holes, the first screen plate is provided with a second mounting hole that is bolted and fastened to the first mounting hole, and the second screen plate is provided with a third mounting hole that is bolted and fastened to the first mounting hole.
[0019] The second mounting hole and the third mounting hole are strip-shaped holes.
[0020] Preferably, a handle groove is provided on the top of the front end face and / or the rear end face of the storage box.
[0021] Preferably, an observation window is provided on the front end face and / or the middle of the rear end face of the storage box, and the observation window extends through the storage trough.
[0022] Preferably, the suction cup unit includes at least one vacuum nozzle.
[0023] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0024] 1. In this utility model, after the suction cup unit adsorbs the membrane, the first driving unit will drive the suction cup unit to shake up and down at the sieve thread opening. By using the thread structure of the sieve thread opening to contact the edge of the membrane, the excess membrane is peeled off, so that the vacuum nozzle can only adsorb one membrane at a time, realizing automated membrane separation, saving labor costs and improving production efficiency.
[0025] 2. In this utility model, the thread structure of the sieve thread is a continuous spiral protrusion with a triangular cross-section, which is made on a cylindrical surface. The protrusion structure with a triangular cross-section can quickly peel off the adhered membrane. When the circular thread structure contacts the edge of the membrane, it can make the edge of the membrane evenly stressed. The membrane that falls back into the storage tank is relatively flat and is not easy to fold or deform. This facilitates the vacuum nozzle to carry out the next round of adsorption process and is not easy to break. It can quickly separate the membrane. Attached Figure Description

[0047] Example
[0048] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a membrane separation device, including a storage mechanism 10 and a material handling mechanism 11. The storage mechanism 10 includes a loading platform 101, a storage bin 102, a screening plate 103, and a placement rack 104 for placing the storage bin 102. The placement rack 104 is disposed on the loading platform 101, and the screening plate 103 is disposed on the top surface of the storage bin 102. At least one storage trough 1021 is provided inside the storage bin 102, and the screening plate 103 is provided with a screening thread 1031 aligned with the opening of the storage trough 1021. The material handling mechanism 11 includes a support frame 111 that elevates itself, a suction cup unit 112, a first drive unit 113 that drives the suction cup unit 112 to move up and down, and a second drive unit 114 that drives the first drive unit 113 to move horizontally toward or away from the storage mechanism 10. The suction cup unit 112 includes at least one vacuum nozzle 1121. The first drive unit 113 and the second drive unit 114 can be a linear motor, a cylinder or a hydraulic cylinder. Optionally, the first drive unit 113 and the second drive unit 114 can be an SC32X25 standard cylinder.
[0049] Specifically, the storage tank 1021 of the storage box 102 contains a diaphragm for assembly into the receiver. The second drive unit 114 drives the suction cup unit 112 to move horizontally toward the storage mechanism 10. When the suction cup unit 112 moves to the position of the storage box 102, it moves up and down under the drive of the first drive unit 113 and adsorbs the diaphragm. Since the diaphragm is easily stuck together under the action of static electricity and other factors, after the suction cup unit 112 adsorbs the diaphragm, the first drive unit 113 will drive the suction cup unit 112 to shake up and down at the screen thread 1031. The thread structure of the screen thread 1031 contacts the edge of the diaphragm to peel off the excess diaphragm, so that the vacuum nozzle 1121 can only adsorb one diaphragm at a time, realizing automated separation of diaphragms, saving labor costs and improving production efficiency.
[0050] Furthermore, since the thread structure of the screen thread 1031 is a continuous spiral protrusion with a triangular cross-section made on a cylindrical surface, when the suction unit 112 adsorbs the membrane at the screen thread 1031 and shakes it up and down, the protrusion structure with a triangular cross-section can quickly peel off the adhered membrane. Moreover, when the circular thread structure contacts the edge of the membrane, it can make the edge of the membrane evenly stressed. The membrane that falls back into the storage tank 1021 is relatively flat and is not prone to folding or deformation. This makes it convenient for the vacuum nozzle 1121 to carry out the next round of adsorption process, and it is not easy to break. It can quickly separate the membrane.
[0051] like Figure 1 and Figure 2As shown, there are two placement racks 104, which are symmetrically arranged on the loading platform 101. A rotary power unit 1012 for driving the loading platform 101 to rotate is provided in the middle of the loading platform 101. One optional rotary power unit 1012 is a QSW50-90 rotary cylinder.
[0052] Specifically, one placement rack 104 is located on the side of the loading platform 101 near the suction cup unit 112 to facilitate the suction cup unit 112 in adsorbing the film; another placement rack 104 is located on the other side of the loading platform 101 to hold the storage bin 102 for material replacement. When the film in the storage bin 102 located on the side of the loading platform 101 near the suction cup unit 112 is exhausted, the rotary power unit 1012 drives the loading platform 101 to rotate, thereby rotating the other storage bin 102 to the side of the suction cup unit 112, realizing automatic material replacement and effectively improving production efficiency.
[0053] like Figure 1 and Figure 2 As shown, this embodiment also includes a monitoring sensor 12, which includes a sensor receiver 121 and a sensor transmitter 122. The sensor receiver 121 is located on one side of the storage bin 102, and the sensor transmitter 122 is located on the other side of the storage bin 102. A monitoring through-hole 1022 is provided on the top of the storage bin 102, penetrating both sides of the storage bin 102 and passing through the storage trough 1021. The monitoring beam of the monitoring sensor 12 is aligned with the monitoring through-hole 1022. An optional monitoring sensor 12 is a PM-K54 through-beam infrared photoelectric sensor.
[0054] Specifically, the sensor transmitter 122 of the monitoring sensor 12 emits a monitoring beam that passes through the monitoring through hole 1022 of the storage bin 102. When there are enough membranes in the storage bin 102, the monitoring beam will be blocked by the membranes. When there are not enough membranes in the storage bin 102, the monitoring beam will pass through the storage trough 1021 and be received by the sensor receiver 121, thereby transmitting a signal to issue a warning or triggering the rotation power unit 1012 to rotate, thereby realizing automatic material changing and improving production efficiency.
[0055] like Figure 2 As shown, in this embodiment, the placement rack 104 includes two symmetrically arranged slots 1041, and the bottom of the slots 1041 is provided with placement blocks 10411 for supporting the storage box 102. The placement blocks 10411 of the placement rack 104 can support the bottom of the storage box 102 and use the slots 1041 to engage the two sides of the storage box 102 to ensure the stability of the storage box 102.
[0056] like Figure 1 and Figure 2As shown, this embodiment also includes a clamping member 1011, which is disposed on the loading platform 101 and presses against the storage box 102. To facilitate material replacement, there is a certain gap between the slot 1041 of the placement rack 104 and the storage box 102. When the storage box 102 is placed on the placement rack 104, the clamping member 1011 is rotated to press against one side of the storage box 102. At this time, the other side of the storage box 102 will press against the slot 1041, thereby achieving the locking of the storage box 102 and further ensuring the stability of the storage box 102.
[0057] like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment also includes a lifting mechanism 13, which is located directly below the placement frame 104. The lifting mechanism 13 includes at least one lifting member 131 and a lifting power unit 132 for driving the lifting member 131 to move up and down. The bottom of the storage tank 1021 is provided with a lifting hole 10211 that is aligned with the lifting member 131. An optional lifting power unit 132 is an SC32X25 standard cylinder.
[0058] Specifically, the diameter of the lifting hole 10211 is smaller than the diameter of the diaphragm to ensure that the diaphragm can be stored in the storage tank 1021. The lifting power unit 132 can drive the lifting member 131 to rise and fall and extend into the storage tank 1021 through the lifting hole 10211 to lift the diaphragm so that the suction cup unit 112 can adsorb the diaphragm. Thus, without affecting the adsorption of the diaphragm by the suction cup unit 112, the storage tank 1021 has sufficient depth to accommodate more diaphragms, reduce the number of material changes, and improve production efficiency.
[0059] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the screening plate 103 includes a first screening plate 1032 and a second screening plate 1033. The first screening plate 1032 and the second screening plate 1033 are assembled to form a screening threaded opening 1031. The top surface of the storage box 102 is provided with a plurality of first mounting holes 1023. The first screening plate 1032 is provided with a second mounting hole 10321 that is bolted to the first mounting hole 1023. The second screening plate 1033 is provided with a third mounting hole 10331 that is bolted to the first mounting hole 1023. The second mounting hole 10321 and the third mounting hole 10331 are strip-shaped holes.
[0060] Specifically, since the second mounting hole 10321 and the third mounting hole 10331 are strip-shaped holes, the strip-shaped holes facilitate the adjustment of the distance between the first screen plate 1032 and the second screen plate 1033, thereby adjusting the diameter of the screen thread 1031, so as to accommodate diaphragms of different sizes and expand the range of applications.
[0061] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a handle groove 1025 is provided on the front end face and / or the top of the rear end face of the storage box 102. The handle groove 1025 is used to facilitate the taking and putting away of the storage box 102 for material replacement.
[0062] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, an observation window 1024 is provided on the front end face and / or the middle of the rear end face of the storage box 102. The observation window 1024 is provided through the storage tank 1021, and the situation inside the storage tank 1021 can be observed through the observation window 1024.
[0063] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
