Description

Technical Field

[0001] This invention relates to the field of electronic cigarette manufacturing technology, and in particular to an automatic microphone feeding and fabrication device. Background Technology

[0002] The e-cigarette microphone is a component of an e-cigarette, primarily used to detect the user's inhalation. A dedicated MCU (usually an 8-bit microcontroller) drives the atomizer. The microphone is essentially an airflow sensor; when the user inhales, the airflow sensor responds and triggers the control circuit, causing the atomizer to activate and produce vapor. Currently, e-cigarette microphones include those with soldered pins and those without. Microphones without soldered pins offer advantages such as a solder-free pin design, higher production efficiency, and improved overall product reliability. Furthermore, they feature an integrated MOS switch, supporting high-current discharge, thus giving the e-cigarette a more powerful burst of vapor.

[0003] Therefore, leadless electronic cigarette microphones are becoming increasingly widely used. These microphones are typically stored in rolls after production. When these microphones are needed to be assembled into electronic cigarette products, the microphone rolls must first be loaded onto a chip mounter. Loading the microphone rolls involves a series of operations, including winding, fixing the roll, and adjusting the head position. The winding process is cumbersome, time-consuming, and labor-intensive. It is evident that there is still room for improvement in the current microphone roll winding process. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the background art.

[0005] This invention provides an automatic fabric feeding device for microphones, comprising:

[0006] frame;

[0007] A vibratory feeder, which is mounted on the frame, includes a discharge chute.

[0008] A visual inspection mechanism is used to detect the orientation of the microphone on the discharge chute.

[0009] A flipping mechanism is used to flip the microphone on the discharge chute.

[0010] The beneficial effects of this invention are as follows: The automatic microphone feeding and fabrication device is equipped with a vibratory feeder. Before feeding, multiple rolls of microphone material are removed at once and placed into the vibratory feeder. The vibratory feeder feeds the microphone to the discharge chute. A vision detection mechanism identifies the front and back of the microphone. Based on the vision detection mechanism's identification of the microphone's front and back, a flipping mechanism flips the microphone so that the front and back of the microphone exiting from the discharge chute are aligned. This automatic microphone feeding and fabrication device can load multiple rolls of microphone material at once. Compared with the method of using a patch panel feeding machine, it reduces manual loading, unloading, and adjustment of the material head, improves the microphone feeding efficiency, reduces manual intervention, and helps to reduce costs.

[0011] As some sub-solutions of the above technical solutions, the flipping mechanism includes an air blowing pipe and an air blowing device. The air blowing device is mounted on the frame, and the output end of the air blowing device is connected to the air blowing pipe. An air blowing hole is provided on the discharge slide, and the air blowing hole is inclined upward. The air blowing pipe is connected to the air blowing hole.

[0012] As some sub-solutions of the above technical solution, the flipping mechanism also includes a flipping structure, which is used to make the microphone leave the discharge chute with the circuit board facing upwards.

[0013] As some sub-solutions of the above technical solution, the flipping structure is a twisting slide, which includes an entry end and an exit end. During the continuous extension of the twisting slide from the entry end to the exit end, the positions of the bottom surface and the top surface are reversed.

[0014] As a sub-solution of the above technical solution, the flipping mechanism also includes an isolation structure that separates other microphones when the microphone is flipped.

[0015] As some sub-solutions of the above technical solution, the discharge chute is provided with a front clearance hole and a rear clearance hole, both of which are transversely connected to the discharge chute. The front clearance hole and the rear clearance hole are located on the front and rear sides of the air blowing hole, respectively. The isolation structure includes an isolation driver, a front partition, and a rear partition. The isolation driver is mounted on the frame and is driven to both the front partition and the rear partition. The front partition and the rear partition enter and exit the discharge chute along the front clearance hole and the rear clearance hole, respectively.

[0016] As some sub-solutions of the above technical solutions, the discharge slide is also provided with a push-off clearance hole, which runs through the discharge slide laterally. The isolation structure also includes a pusher, which is driven by the isolation driver to move in and out of the discharge slide along the push-off clearance hole.

[0017] As some sub-solutions of the above technical solution, the overturning clearance hole extends laterally through the two side walls and bottom wall of the discharge slide. The isolation structure also includes a circulation belt and a pushing rod. The circulation belt is disposed on the frame. One end of the pushing rod is hinged to the isolation driver, and the other end is hinged to the push head. The push head slides along the circulation belt so that after passing the overturning clearance hole laterally, the push head retracts downward to the bottom of the discharge slide and returns.

[0037] The following is combined with Figures 1 to 5 Embodiments of the present invention will be described.

[0038] This embodiment relates to an automatic microphone feeding and fabric distribution device.

[0039] The automatic fabric feeding device for microphones includes:

[0040] frame;

[0041] Vibratory feeder 1, the vibratory feeder 1 is mounted on the frame, and the vibratory feeder 1 includes a discharge chute 11;

[0042] Visual inspection mechanism 2, which is used to detect the orientation of the microphone 9 on the discharge chute 11;

[0043] A flipping mechanism is used to flip the microphone 9 on the discharge chute 11.

[0044] In this embodiment, the microphone 9 is disc-shaped and includes a cylindrical cover 91 and a circuit board 92. The circuit board 92 is embedded in the cylindrical cover 91 and the solder pads 921 of the circuit board 92 are exposed downwards so that it can enter the downstream related welding production line to be wired on the solder pads 921 and subsequently assembled into a finished product.

[0045] When using the automatic microphone feeding and fabric distribution device, microphones 9 are manually or through other means removed from multiple rolls of microphone 9 fabric at once and placed into the vibrating plate 1. The vibrating plate 1 feeds the microphones 9 one by one along the discharge chute 11, and the vision detection mechanism 2 identifies the orientation of the microphones 9. In this embodiment, the positive orientation of the microphone 9 is with the circuit board 92 of the microphone 9 at the bottom and the cylindrical cover 91 at the top; the negative orientation is with the circuit board 92 of the microphone 9 at the top and the cylindrical cover 91 at the bottom.

[0046] When designing the automatic microphone feeding and fabric distribution device, the microphone 9 on the discharge slide 11 can be preset to be in the normal state when facing forward and in the state to be flipped when facing backward, or the microphone 9 can be preset to be in the normal state when facing backward and in the state to be flipped when facing forward. When the vision detection mechanism 2 identifies that the corresponding microphone 9 is in the state to be flipped, the flipping mechanism is activated to flip the microphone 9, so that the microphones 9 output along the discharge slide 11 are transported to the downstream workstation for processing in the same direction.

[0047] This automatic microphone feeding and fabrication device is equipped with a vibratory feeder 1. Before feeding, multiple rolls of microphone 9 are removed at once and placed into the vibratory feeder 1. The vibratory feeder 1 vibrates the microphones to the discharge chute 11. A vision detection mechanism 2 identifies the front and back of the microphones 9. Based on the results of the vision detection mechanism 2, the flipping mechanism flips the microphones 9 so that the front and back of the microphones 9 exiting from the discharge chute 11 are aligned. This automatic microphone feeding and fabrication device can load multiple rolls of microphone 9 at once. Compared with the feeding method of using a patch panel, it reduces the manual loading, unloading and adjustment of the rolls, improves the feeding efficiency of microphones 9, reduces manual intervention, and helps to reduce costs.

[0048] Specifically, the flipping mechanism includes an air blowing pipe (not shown in the figure) and an air blowing device (not shown in the figure). The air blowing device is mounted on the frame, and its output end is connected to the air blowing pipe. An air blowing hole 111 is provided on the discharge chute 11, and the air blowing hole 111 is inclined upwards. The air blowing pipe is connected to the air blowing hole 111. The upwardly inclined air blowing hole 111 faces the corner of the microphone 9. When it is necessary to flip the microphone 9, the air blowing device is activated to supply air to the air blowing hole 111 through the air blowing pipe, blowing air from the corner of the microphone 9 to generate an upward force on the microphone 9 pointing to the other side, thus flipping the microphone 9. The flipping mechanism using air blowing can easily and quickly achieve the flipping operation of the microphone 9.

[0049] When using the air blowing device to flip the microphone 9, it is easier to keep the microphone 9 in a lower center of gravity position. Since the overall weight of the microphone 9 is concentrated on the side where the circuit board 92 is located, in this embodiment, the normal state is selected with the cylindrical cover 91 on top and the circuit board 92 on the bottom; the state with the cylindrical cover 91 on the bottom and the circuit board 92 on top is the state to be flipped. When the microphone 9 is set to the normal state with the circuit board 92 on the bottom, a flipping structure needs to be designed to flip the microphone 9 to the position where the circuit board 92 faces upwards before it is output from the discharge chute 11, so that the solder pads 921 are exposed. Therefore, the flipping mechanism also includes a flipping structure, which is used to make the microphone 9 leave the discharge chute 11 with the circuit board 92 facing upwards.

[0050] The flipping structure is a torsion slide (not shown in the figure), which includes an inlet end and an outlet end. As the torsion slide extends continuously from the inlet end to the outlet end, the positions of its bottom and top surfaces are reversed. This allows the microphone 9 to rotate vertically after passing through the torsion slide, enabling it to exit the discharge slide 11 with the circuit board 92 positioned above it, and enter the downstream soldering station for easy wire bonding to the solder pads 921 on the circuit board 92.

[0051] Ideally, the vibration rhythm of the vibratory plate 1 should match the flipping rhythm of the air blowing device, allowing the air blowing device to complete the flipping of the microphone 9 during the intervals between vibrations of the vibratory plate 1. This prevents the microphone 9 from getting stuck after being blown up and unable to fall back onto the discharge chute 11. However, this presents a certain stability issue during processing. Therefore, in this embodiment, the flipping mechanism also includes an isolation structure. This isolation structure separates other microphones 9 during flipping, ensuring that the microphone 9 can fall back onto the discharge chute 11 after flipping. Specifically, separating other microphones 9 means separating the microphones 9 located in front of and behind the air blowing hole 111, ensuring that the microphone 9 directly opposite the air blowing hole 111 is not disturbed by other microphones 9 during flipping.

[0052] The discharge chute 11 is provided with a front clearance hole and a rear clearance hole, both of which are transversely connected to the discharge chute 11. The front clearance hole and the rear clearance hole are located on the front and rear sides of the air blowing hole 111, respectively. The isolation structure includes an isolation driver 31, a front partition 32, and a rear partition 33. The isolation driver 31 is mounted on the frame and is driven to both the front partition 32 and the rear partition 33. The front partition 32 and the rear partition 33 enter and exit the discharge chute 11 along the front clearance hole and the rear clearance hole, respectively. After the front clearance hole and the rear clearance hole are opened on the discharge slide 11, when the microphone 9 needs to be flipped by the air blowing device, the isolation driver 31 is first activated to drive the front isolation plate and the rear isolation plate into the discharge slide 11, separating the other microphones 9 in front and behind. This ensures that the microphone 9 at the air blowing hole 111 is not disturbed by other microphones 9 when it is flipped, and ensures that the microphone 9 can be flipped normally.

[0053] The discharge chute 11 is also provided with a push-off clearance hole, which extends laterally through the discharge chute 11. The isolation structure also includes a push head 34, which is driven by the isolation driver 31 to move in and out of the discharge chute 11 along the push-off clearance hole. In this way, while the air blowing device blows air into the air blowing hole 111 through the air blowing pipe and blows up the microphone 9, the push head 34 also pushes the lower side of the microphone 9 to further ensure that the microphone 9 completes the flipping action.

[0054] Furthermore, to ensure that the pusher head 34 does not interfere with the flipped microphone 9 upon return, the overturning clearance hole extends laterally through both side walls and the bottom wall of the discharge chute 11. The isolation structure also includes a circulating belt 35 and a pushing rod 36. The circulating belt 35 is mounted on the frame. One end of the pushing rod 36 is hinged to the isolation driver 31, and the other end is hinged to the pusher head 34. The pusher head 34 slides along the circulating belt 35, allowing it to pass laterally through the overturning clearance hole and then retract downwards to return below the discharge chute 11. It is understood that the circulating belt 35 is supported by rollers located on both sides, enabling the circulating belt 35 to rotate stably. The isolation structure of the automatic feeding and fabric feeding device also includes a circulating belt 35 and a push rod 36. When the isolation driver 31 is activated, the push rod 36 can also drive the push head 34 to slide along the circulating belt 35. The movement of the front partition 32, the rear partition 33 and the push head 34 can be achieved by a single driving element of the isolation driver 31. The device achieves multiple functions with a simple structure, and is compact and efficient.

[0055] The isolation actuator 31 is a cylinder. The isolation actuator 31 uses a cylinder, which can use a blowing device as a common air supply source.

[0056] The visual inspection mechanism 2 identifies the orientation of the microphone 9 using a fiber optic sensor. Specifically, a reflective fiber optic sensor is used. Reflective fiber optic sensors determine the shape of an object by acquiring the light reflected from it. Their working principle utilizes the different strain distributions within the cross-section of an optical fiber under different shapes. Therefore, after pre-setting the strain distribution for the front of the microphone 9, for example, pre-setting the orientation of the microphone 9 (circuit board 92 at the bottom), if the strain distribution acquired by the fiber optic sensor is inconsistent with the preset value, it indicates that the microphone 9 is facing the wrong direction.

[0057] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
