DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The directions mentioned in this specification are based on the directions shown in the drawings and only represent relative positions, not absolute positions.

[0026] like Figure 1 As shown, a mechanical diaphragm housing machine includes a frame 10, a front side of the frame 10 (with Figure 1 A housing assembly 40 is installed (see the orientation shown). A housing feeder 34 and a diaphragm feeder 30 are mounted side by side on the frame 10 behind the housing assembly 40. An operating panel 20 for a worker to operate the machine is mounted on the right corner of the frame 10 behind the diaphragm feeder 30. In this embodiment, the housing feeder 34 and the diaphragm feeder 30 are vibrating discs.

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, the shell entering assembly 40 comprises a positioning disc rotating by a motor, the positioning disc is installed on the frame 10 through a mounting seat 42, the mounting seat 42 is in a right trapezoidal structure, the upper plate of the mounting seat 42 is an inclined surface of the right trapezoid, that is, the upper plate of the mounting seat 42 is an inclined plate surface, the front side is lower and the rear side is higher, the disc surface of the positioning disc is parallel to the upper plate of the mounting seat 42, that is, the positioning disc is inclined, the positioning disc is located on the upper side of the upper plate of the mounting seat 42, the motor is installed on the lower side of the upper plate of the mounting seat 42, the power output shaft 480 of the motor penetrates the upper plate, the positioning disc is fixed on the power output shaft 480 of the motor through a connecting key 49. A plurality of shell positioning grooves 430 and diaphragm positioning grooves 440 are correspondingly arranged on the circumferential side of the positioning disc, the diaphragm positioning grooves 440 are located above the shell positioning grooves 430. The rear side of the positioning disc (that is, the side with higher position) is connected with the shell conveying channel 36 and the diaphragm conveying channel 32, the shell conveying channel 36 is located on the left side and the diaphragm conveying channel 32 is located on the right side, because the positioning disc rotates in the clockwise direction, the shell conveying channel 36 is located at the upstream position of the diaphragm conveying channel 32. The shell conveying channel 36 is connected between the shell feeder 34 and the positioning disc, the shell conveying channel 36 is a straight line feeder in the embodiment, which is used to feed the shells vibrated out of the shell feeder 34 into the shell positioning grooves 430 on the positioning disc in a single column. The diaphragm conveying channel 32 is connected between the diaphragm feeder 30 and the positioning disc, the diaphragm conveying channel 32 is also a straight line feeder in the embodiment, which is used to feed the diaphragms vibrated out of the diaphragm feeder 30 into the diaphragm positioning grooves 440 on the positioning disc in a single column. The front side of the positioning disc (that is, the side with lower position) is connected with the inclined guide disc 50, the inclined direction of the guide disc 50 is consistent with the inclined direction of the positioning disc, the shells with diaphragms will automatically slide onto the guide disc 50 under the action of gravity and centrifugal force when the positioning disc rotates to the low side, and then are collected and enter the next assembly process of the microphone.

[0028] As Figure 2 , Figure 3 and Figure 5As shown in the drawings, in order to facilitate processing, the positioning disc of the embodiment preferably comprises a shell positioning disc 43 and a diaphragm positioning disc 44 arranged in a stack, and the diaphragm positioning disc 44 is located above the shell positioning disc 43. The shell positioning disc 43 and the diaphragm positioning disc 44 are simultaneously installed on the upper side of the mounting seat 42 and are fixedly connected to the power output shaft 480 of the motor through the connecting key 49, and are driven to rotate synchronously by the motor. The shell positioning groove 430 is arranged on the circumferential side of the shell positioning disc 43, specifically on the circumferential side of the upper surface of the shell positioning disc 43, that is, the shell positioning groove 430 is a lower groove. The diaphragm positioning groove 440 is arranged on the circumferential side of the diaphragm positioning disc 44, specifically on the circumferential side of the lower surface of the diaphragm positioning disc 44, that is, the diaphragm positioning groove 440 is an upper groove. A plurality of shell positioning grooves 430 are closely arranged around the shell positioning disc 43, and similarly a plurality of diaphragm positioning grooves 440 are also closely arranged around the diaphragm positioning disc 44, and the number of the shell positioning grooves 430 is the same as the number of the diaphragm positioning grooves 440, and they are arranged oppositely in the up-down direction.

[0029] As shown in the drawings, Figure 3 , Figure 4 and Figure 5 As shown in the drawings, the shell positioning disc 43 and the diaphragm positioning disc 44 are provided with a diaphragm blocking plate 45, which is approximately an L-shaped sheet structure. The vertical part of the diaphragm blocking plate 45 is located between the shell conveying channel 36 and the diaphragm conveying channel 32 and is fixedly connected to the mounting seat 42 through a fastener. The horizontal part of the diaphragm blocking plate 45 is located between the shell positioning disc 43 and the diaphragm positioning disc 44 and is located at the position where the positioning disc connects with the diaphragm conveying channel 32. The upper surface of the diaphragm blocking plate 45 cooperates with the diaphragm positioning groove 440 to form a diaphragm positioning space. The discharge port of the diaphragm conveying channel 32 is flush with the upper surface of the diaphragm blocking plate 45. The diaphragm enters the positioning space from the diaphragm conveying channel 32. The diaphragm positioning groove 440 plays a role in positioning the diaphragm in the horizontal direction, which can ensure that the diaphragm can accurately fall into the shell. The diaphragm blocking plate 45 plays a role in positioning the diaphragm in the vertical direction, which can prevent the diaphragm from being vertically flipped. In the embodiment, the edge of the diaphragm blocking plate 45 is located at about one-third of the downstream shell positioning groove 430. The diaphragm will move downstream clockwise in the positioning space as the shell positioning disc 43 and the diaphragm positioning disc 44 rotate. When the diaphragm moves out of the area of the diaphragm blocking plate 45, the diaphragm will gently fall into the shell under the clamping action of the diaphragm blocking plate 45 and the diaphragm positioning groove 440 on the one-third part of the shell positioning groove 430, and will not be vertically flipped.

[0030] As shown in the drawings, Figure 2 , Figure 3 and Figure 5 As shown in the drawings, a material blocking wall 41 is arranged on the circumferential side of the positioning disc between the diaphragm conveying channel 32 and the guide plate 50. The material blocking wall 41 is an arc-shaped structure and surrounds the outside of the positioning disc, which can effectively prevent the material in the shell positioning groove 430 from being thrown out due to the centrifugal force of the rotation of the positioning disc.

[0031] As Figure 3 , Figure 4 and Figure 5 together shown, the shell detection sensor 47 is arranged at the discharge end of the shell conveying channel 36, for detecting whether the shell enters the shell positioning groove 430, if the shell enters, the motor runs normally, if the shell does not enter, the motor stops rotating, and the motor continues to run after the shell enters. The diaphragm detection sensor 46 is arranged at the discharge end of the diaphragm conveying channel 32, for detecting whether the diaphragm enters the diaphragm positioning groove 440, similarly, if the diaphragm does not enter, the motor stops rotating, and the motor continues to run after the diaphragm enters. The shell detection sensor 47 and the diaphragm detection sensor 46 can ensure that the semi-finished product falling into the guide disc 50 is a qualified product. The shell detection sensor 47 and the diaphragm detection sensor 46 are preferably optical fiber sensors, the transmitting end or the receiving end is located above the positioning disc, and the receiving end or the transmitting end is also correspondingly installed below the positioning disc. The through hole for the optical fiber to pass through is arranged on the shell positioning groove 430, the diaphragm positioning groove 440 and the diaphragm blocking plate 45.

[0032] As Figure 1 , Figure 2 , Figure 4 and Figure 5 together shown, the positioning disc of the mechanical diaphragm shell machine is inclined, and the shell is sent into the shell positioning groove 430 by the shell feeder 34 and the shell conveying channel 36 on the side where the position is higher. When the diaphragm conveying channel 32 is rotated to the discharge end position, the shell positioning groove 430 has a shell, the diaphragm is sent into the diaphragm positioning groove 440 by the diaphragm feeder 30 and the diaphragm conveying channel 32, and the diaphragm will automatically fall into the shell with the continuous rotation of the positioning disc, thereby completing the diaphragm shell process. When the positioning disc is rotated to the side where the position is lower, the shell with the diaphragm will slide out of the shell positioning groove 430 under the action of gravity and centrifugal force, and fall into the guide disc 50. The mechanical diaphragm shell machine does not need pneumatic components to complete the diaphragm shell process, thereby greatly simplifying the structure of the equipment, reducing the volume of the equipment, and greatly improving the safety of production, reducing the cost of the equipment itself and the operation cost. The utility model is not limited to the above specific embodiments, and those skilled in the art can make various changes without creative labor, which are within the protection scope of the utility model.
