[0045] In order to achieve the coordination and continuity of microphone assembly, the process flow of microphone assembly production has been improved. For specific processes, see Figure 5 Each process is implemented by different mechanisms. Based on the above process flow, a control method for realizing microphone assembly production was developed, as follows:

[0046] A first rotary loading mechanism is provided at the first workstation, and the first rotary loading mechanism is controlled to rotate so as to distribute the first assembly workpiece to its loading port by centrifugal force;

[0047] A grouping mechanism is provided at the second station. The grouping mechanism includes two spacer needles. The two spacer needles are controlled to be alternately inserted into the conveying array of the first assembly workpieces. The first assembly workpieces conveyed between the two spacer needles in an alternating cycle are grouped into one group.

[0048] A spacing adjustment mechanism, a first translation mechanism, and two spacing adjustment points are set at the third station, and the first translation mechanism is controlled to synchronously translate the spacing adjustment mechanism from the first spacing adjustment point to the second spacing adjustment point, and the first assembled workpiece is transferred from the third station to below the main pressing platform of the fourth station;

[0049] When the first translation mechanism moves to the first spacing adjustment point, the partition at the front corresponds to the workpiece between the two spacer needles; when the partition extends forward and is inserted between the first assembled workpieces of the same group to increase the spacing between the workpieces, the spacer needles at the rear retract and the spacer needles at the front extend forward; when the translation mechanism moves to the second spacing adjustment point, the partition at the rear moves to under the main pressing platform of the fourth station. At this time, the spacer needles at the rear extend forward and the spacer needles at the front retract. At the same time, the first translation mechanism is controlled to translate the spacing adjustment mechanism to the first spacing adjustment point;

[0050] A tablet pressing mechanism is set at the fourth station. The tablet pressing mechanism includes a main pressing platform. When the first assembled workpiece is transferred to the bottom of the main pressing platform of the fourth station, the pressing slider is controlled to press down. After the pressing slider is pressed down to the right position, the tablet pressing is completed and the pressing slider is lifted;

[0051] A second translation mechanism and a coil clamping mechanism are provided at the fifth station. When the pressing slider is pressed down, the coil clamping mechanism is controlled to release the coil; when the pressing slider is lifted, the coil clamping mechanism is controlled to clamp the coil. The second translation mechanism drives the coil clamping mechanism to move backward, pulling the coil to move a set distance, and then resets.

[0052] A second rotating mechanism is provided at the sixth station to control the rotation of the second rotating loading mechanism and to distribute the second assembly workpiece to its loading port by centrifugal force;

[0053] An assembly mechanism and two assembly points are provided at the seventh station, wherein the first assembly point is provided at the end of the sliding path of the first ejector rod, and the second assembly point is provided in parallel with the first assembly point and is located on the sliding path of the first ejector rod;

[0054] When the workpiece reaches the first assembly point, the first push rod is controlled to extend forward to push the second assembled workpiece on the second assembly point into the first assembled workpiece on the first assembly point. The second push rod is controlled to move after the first push rod is extended to push the workpiece assembled from the first assembly point forward.

[0055] Based on the above process flow and control method, a microphone assembly production line was developed. Figures 2 to 5 Commonly shown:

[0056] The first station corresponds to a loading process, and a first rotary loading mechanism is set at the first station. The first rotary loading mechanism includes a first turntable 20. The first turntable 20 rotates and distributes the first assembled workpiece to its loading port through centrifugal force; specifically, the first rotary loading mechanism includes a first turntable 20 driven by a first motor, and a discharge port is provided on one side of the first turntable 20; the first turntable 20 includes a turntable body 21, and an annular support frame 22 is provided on the outer side of the turntable body 21. The position of the turntable body 21 near the discharge port is provided with a A guide plate 23 is provided, and a baffle 24 is provided on the inner side of the guide plate 23, and the baffle 24 and the end of the guide plate 23 are combined to form a discharge port; a rotating shaft connected to the motor transmission is provided in the middle position of the turntable body 21, and a support shaft 25 is passed through the middle position of the rotating shaft, and the top end of the support shaft 25 extends out of the turntable body 21, and a top cover 26 is installed on the top end of the support shaft 25, and a paddle 27 is installed on the outer side of the top cover 26. When the turntable body 21 rotates, the paddle 27 shifts the workpiece to the edge of the turntable body 21, and the workpiece enters the discharge port formed by the baffle 24 and the end of the guide plate 23 and is transmitted to the next workstation.

[0057] The first assembled workpiece is transferred from the first workstation to the second via a first feed mechanism 91. This mechanism comprises a conveyor track 911, below which is mounted a vibrator 912. Above this track is a feed trough 913 to facilitate the passage of individual workpieces. The discharge port formed by the ends of the baffle 24 and guide plate 23 interfaces with the feed trough 913. Under the action of the vibrator 912, the workpieces sequentially enter the feed trough 913. The first feed mechanism begins at the loading port of the first rotary loading mechanism in the first workstation and ends at the first spacing adjustment point of the spacing adjustment mechanism in the third workstation.

[0058] The second workstation corresponds to the grouping process. A grouping mechanism is set at the second workstation. The grouping mechanism includes two spacer needles 31. The spacer needles 31 are installed on the push rod of the first cylinder 32. Each spacer needle 31 is driven by a cylinder. The two spacer needles 31 are alternately inserted into the conveying array of the first assembly workpiece; the first assembly workpiece conveyed between the two spacer needles in an alternating cycle is divided into a group. In this embodiment, the number of workpieces in each group is 3.

[0059] The control method of the grouping process is: control the spacer needle located upstream to retract, and the spacer needle located downstream to extend to block the advancement of the first assembly workpiece. When the workpieces are gathered into a group of three, control the spacer needle located upstream to extend to block the advancement of the first assembly workpiece, and the spacer needle located downstream to retract, and the first component workpiece divided into a group continues to move forward.

[0060] The third station corresponds to the distance adjustment process, and a distance adjustment mechanism and two distance adjustment points are set at the third station, such as Figure 4 As shown, the spacing adjustment mechanism includes a plurality of partitions 41 with spacing teeth 410, and the partitions 41 are arranged along the conveying direction of the first assembly workpiece. In this embodiment, the number of partitions 41 is three, and the spacing spacing of the partitions located downstream in the conveying direction is greater than the spacing spacing of the partitions located upstream. The installation centers of the partitions 41 are installed on the first installation base plate 42 at equal intervals, that is, the distances between the installation positions of several partitions 41 are equal. The partitions 41 are installed on the first installation base plate 42 at the installation position through fasteners. The first installation base plate 42 is connected to the push rod of the second cylinder 43, and the moving direction of the push rod of the second cylinder 43 is perpendicular to the conveying direction of the first assembly workpiece.

[0061] Each partition 41 is separated by three grooves for accommodating workpieces by the partition teeth 410. When the second cylinder 43 pushes out the push rod, the partition 41 is inserted into the workpiece, and the three workpieces are separated by the partition teeth 410. The partition teeth of the first partition are shallower to facilitate the separation of the workpieces. The partition teeth of the second partition are slightly larger than the first partition to increase the spacing between the workpieces. The partition teeth of the third partition are slightly larger than the second partition to increase the spacing between the workpieces to an appropriate spacing.

[0062] When the spacer teeth 410 are moved to the first spacing adjustment point through the first mounting base plate 42 , they are inserted between the first assembly workpieces of the same group, and the spacing adjustment mechanism is translated to the second spacing adjustment point.

[0063] The first translation mechanism between the third station and the fourth station synchronously translates the spacing adjustment mechanism from the first spacing adjustment point to the second spacing adjustment point, and transfers the first assembly workpiece from the third station to under the main pressing platform of the fourth station. The first translation mechanism includes a second mounting base plate 44, and the first mounting base plate 42 is slidably mounted on the second mounting base plate 44. The first mounting base plate 42 is connected to the push rod of the third cylinder 45, and the moving direction of the push rod of the third cylinder 45 is parallel to the transfer direction of the first assembly workpiece.

[0064] The coordinated control between the spacing adjustment mechanism and the first translation mechanism is as follows: the first mounting base 42 moves to the first spacing adjustment point, and the partition 41 located at the front corresponds to the workpiece between the two spacer needles 31; the push rod of the second cylinder 43 is controlled to be pushed out, driving the first mounting base 42 to be pushed out, and the partition 41 is inserted into the workpiece, and the three partitions gradually increase the spacing between the workpieces. At this time, the spacer needles located at the rear retract and the spacer needles located at the front extend forward; then the third cylinder 45 is controlled to start, and the first mounting base 42 is moved from the first spacing adjustment point to the second spacing adjustment point, and the workpieces of the three spacers 41 are all moved downstream, and the workpiece of the spacer 41 located at the downstreammost station is moved to the bottom of the fourth station main pressing platform 51. At this time, the spacer needles located at the rear extend forward and the spacer needles located at the front retract; the push rod of the second cylinder 43 is controlled to retract, and then the push rod of the third cylinder 45 is controlled to retract, and the third cylinder 45 moves the first mounting base 42 from the second spacing adjustment point to the first spacing adjustment point.

[0065] In order to ensure the coordination of various processes, the distance between the first spacing adjustment point and the second spacing adjustment point is equal to the center distance of the installation positions between two adjacent partitions 41 .

[0066] The alternating period of the spacer needle 31 is equal to the translation period of the spacing adjustment mechanism. When conveying workpieces, the conveying speed of the first feeding mechanism 91 is controlled so that the number of first assembly workpieces conveyed in one alternating period or translation period is equal to the number of first assembly workpieces in each group.

[0067] At the end of the previous translation cycle, the workpiece of the first partition moves downstream a set distance; after the new translation cycle begins, the second partition is inserted between the workpieces translated by the first partition in the previous translation cycle, and the third partition is inserted between the workpieces translated by the second partition in the previous translation cycle. The workpiece of the third partition in the previous translation cycle is translated to the bottom of the main pressing platform of the fourth station, ready for pressing.

[0068] The fourth workstation corresponds to the sheeting process and the unwinding process. A sheeting mechanism and an unwinding mechanism 56 with a coiled material are set at the fourth workstation. The main pressing platform 51 is an important component of the sheeting mechanism. A pressing slider 52 is provided above the main pressing platform 51. A conveying trough 53 for transmitting the first assembled workpiece is located below the main pressing platform 51. The coiled material 17 passes between the main pressing platform 51 and the conveying trough 53. Specifically, a pressure cover 54 is provided above the main pressing platform 51. A fourth cylinder 55 is installed on the pressure cover 54. The pressing slider 52 is installed on the push rod of the fourth cylinder 55. The push rod of the fourth cylinder 55 drives the pressing slider 52 to press down or rise. Stamping dies are installed on the main pressing platform 51 and the pressing slider 52. When the pressing slider 52 punches downward, a gasket 16 is punched out from the coiled material 17 and falls into the outer shell 11.

[0069] The unwinding mechanism 56 is the main execution equipment of the unwinding process. The unwinding mechanism 56 includes an unwinding shaft driven by a motor, and the coil 17 is installed on the unwinding shaft; along the extension direction of the coil 17, a coil guide frame 561 is installed in front of the main pressing platform 51.

[0070] When the first assembly workpiece is transferred to the bottom of the main pressing platform 51 of the fourth station, the pressing slider 52 is controlled to be pressed down, and the gasket 16 is punched out from the coil 17 and falls into the shell 11 of the first assembly workpiece. After the pressing slider 52 is pressed down into place, the pressing is completed and the pressing slider 52 is lifted.

[0071] A second pressing cylinder 511 is provided on one side of the main pressing platform 51, and a second pressing platform 57 is provided on the other side of the main pressing platform 51. A third pressing cylinder 571 is installed on the second pressing platform 57. The coil 17 passes through between the second pressing cylinder 511 and the main pressing platform 51, and between the third pressing cylinder 571 and the second pressing platform 57 in sequence. A guide wheel 562 is installed behind the second pressing platform 57.

[0072] When the pressing slide 52 presses downward, the push rods of the second pressing cylinder 511 and the third pressing cylinder 571 press down and compress the coil 17. When the pressing slide 52 rises, the push rods of the second pressing cylinder 511 and the third pressing cylinder 571 retract and release the coil 17.

[0073] The fifth workstation corresponds to the waste collection process. A second translation mechanism and a coil clamping mechanism are provided at the fifth workstation. When the pressing slider 52 is pressed down, the coil clamping mechanism is controlled to release the coil 17. When the pressing slider 52 is lifted, the coil clamping mechanism is controlled to clamp the coil 17. The second translation mechanism drives the coil clamping mechanism to move backward, pulling the coil 17 through the main pressing platform 51. The coil 17 left after the rear end stamping is completed extends outward through the guide wheel 562 and is collected.

[0074] The second translation mechanism includes a fifth cylinder 61, the coil clamping mechanism is connected to the push rod of the fifth cylinder 61, the moving direction of the push rod of the fifth cylinder 61 is parallel to the conveying direction of the coil 17, the coil clamping mechanism includes a mounting seat 62 connected to the push rod of the fifth cylinder 61, and a first pressing cylinder 63 is provided on the mounting seat 62, and the coil 17 passes between the mounting seat 62 and the first pressing cylinder 63.

[0075] A translation guide rod 58 is installed between the main pressing platform 51 and the second pressing platform 57. The push rod of the fifth cylinder 61 is connected to a slide 64. The slide 64 is slidably installed on the translation guide rod 58. The mounting seat 62 is connected to the slide 64 through a connecting rod in the same direction as the translation guide rod 58.

[0076] The coordination control method between the fourth and fifth stations is as follows: after the workpiece enters the conveying groove 53 below the main pressing platform 51, when the pressing slide 52 is pressed down, the push rods of the second pressing cylinder 511 and the third pressing cylinder 571 press down and press the coil 17, and the push rod of the first pressing cylinder 63 retracts; after the pressing slide 52 is pressed down into place, the stamping is completed, and the pressing slide 52 rises; when the pressing slide 52 rises, the second pressing cylinder 511 and the third pressing cylinder 571 The push rod retracts, loosening the coil 17, the push rod of the first pressing cylinder 63 extends to press the coil 17, the push rod of the fifth cylinder 61 extends, driving the mounting seat 62 and the first pressing cylinder 63 to move backward, pulling the coil 17 to move a set distance, and the coil 17 left after the rear end stamping is completed extends outward and is collected by the guide wheel 562. Subsequently, the push rod of the fifth cylinder 61 retracts, the mounting seat 62 is reset, and the push rod of the first pressing cylinder 63 retracts to loosen the coil; repeat the above actions.

[0077] Preferably, the set distance is equal to the length occupied by the gasket on the coil. If the length occupied by a gasket on the coil is one grid, the fifth cylinder 61 drives the coil clamping mechanism to pull the coil to move one grid.

[0078] The sixth workstation corresponds to the second loading process. A second rotary loading mechanism is set at the sixth workstation. The structure of the second rotary loading mechanism is the same as the first rotary loading mechanism. The position of the discharge port of the second rotary loading is slightly adjusted. The second rotary loading mechanism includes a second turntable 70. The rotation of the second turntable 70 uses centrifugal force to distribute the second assembly workpiece to its loading port.

[0079] The seventh station corresponds to the pushing process, and an assembly mechanism and two assembly points are set at the seventh station.
