[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] like Figure 1, which is a schematic diagram of the structure of an automatic speaker capping device provided by an embodiment of the present invention. The automatic speaker capping device can be applied to the field of mechanical automation technology, especially in an automated production line of speakers.

[0041] Specifically, the automatic capping device for loudspeakers in this embodiment includes an adjustment module 1, a first gluing module 2, a capping module 3, a transfer module 4, and a first working position, a second working position, and a third working position formed on the transfer module 4, wherein the transfer module 4 is equipped with a plurality of positioning carriers 401 for placing loudspeakers to be capped (i.e., the loudspeakers to be capped can be placed on the positioning carriers 401 and fed to the transfer module 4), and each positioning carrier 401 is sequentially transferred to the first working position, the second working position, and the third working position by the transfer module 4. Each positioning carrier 401 can be provided with a limiting groove structure adapted to the bottom of the loudspeaker to be capped, so that when the loudspeaker to be capped is placed on the positioning carrier 401, the bottom of the loudspeaker to be capped can be limited by the limiting groove to prevent the loudspeaker to be capped from being misplaced or detached, and the loudspeaker to be capped is fixed on the positioning carrier 401 by limiting, which is conducive to the taking and placing operation of the loudspeaker to be capped.

[0042] Furthermore, the adjustment module 1 corresponds to the first working position, and is used to adjust the voice coil welding point of the speaker to be capped corresponding to the first working position to the preset position, which is convenient for loading, that is, there is no need to place the speaker to be capped on the positioning carrier 401 in a manner that the voice coil welding point corresponds to the preset position, which can effectively improve the efficiency of loading the speaker to be capped on the positioning carrier 401, thereby improving production capacity. In actual applications, the specific method of loading the speaker to be capped onto the positioning carrier 401 can be determined according to actual conditions; for example, the speaker to be capped is manually loaded onto the positioning carrier 401 of the transfer module 4; or, the above-mentioned speaker automatic capping equipment also includes a loading module, and the speaker to be capped is transferred from the raw material bin to the positioning carrier 401 on the transfer module 4 through the loading module, thereby achieving the automatic loading function of the speaker to be capped.

[0043] The first gluing module 2 corresponds to the second working position, and the first gluing module 2 is mainly used to apply adhesive glue on the voice coil of the speaker to be capped corresponding to the second working position, so as to glue the speaker cap. In addition, the capping module 3 corresponds to the third working position, and the capping module 3 is mainly used to load the speaker cap and install the speaker cap into the voice coil of the speaker to be capped corresponding to the third working position, so that the speaker cap is bonded with the adhesive in the voice coil, thereby fixing the speaker cap in the voice coil of the speaker to be capped, and completing the capping manufacturing of the speaker to be capped.

[0044] In actual applications, the voice coil welding points of the speaker to be capped can be coated together with the adhesive glue (the adhesive glue is made of insulating material and has good insulating properties) applied inside the voice coil by the first gluing module 2; or, the voice coil welding points of the speaker to be capped can be coated with insulating glue applied by the first gluing module 2, and then the first gluing module 2 applies adhesive glue inside the voice coil of the speaker to be capped; the specific implementation method can be determined according to actual conditions.

[0045] The above-mentioned speaker automatic capping equipment transfers the speakers to be capped in sequence by the transfer module 4, so that the position of the voice coil welding point of the speaker to be capped can be adjusted by the adjustment module 1, and then the first glue application module 2 applies a glue layer inside the voice coil of the speaker to be capped, and finally the capping module 3 inserts the speaker cap into the voice coil of the speaker to be capped, thereby completing the capping manufacturing of the speaker to be capped. The entire capping manufacturing process does not require human participation and is fully automatic with a high level of intelligence. It not only greatly reduces labor costs, but also effectively improves production efficiency. It can produce uninterruptedly, is suitable for large-scale production and manufacturing, shortens the production cycle, thereby improving market competitiveness and meeting the needs of projects with large quantities and short cycles.

[0046] Furthermore, since the adjustment module 1, the first gluing module 2, the capping module 3 and the transfer module 4 are all repeatable (ie, they are controlled by a processor to repeat the same action), the manufacturing operation is more controllable and can improve product consistency, thereby reducing product defective rate.

[0047] In one embodiment of the present invention, the above-mentioned speaker automatic capping device also includes a second gluing module 5, and the second gluing module 5 corresponds to the fourth working position formed on the transfer module 4 of the above-mentioned speaker automatic capping device, and is used to apply insulating glue to the voice coil welding point of the speaker to be capped located at the fourth working position, so as to achieve the operation of insulating glue covering the voice coil welding point of the speaker to be capped. By setting the second gluing module 5, the above-mentioned speaker automatic capping device can ensure that the insulating glue is reliably applied to the voice coil welding point, avoid misalignment when applied together with the adhesive glue, and reduce the insulation effect of the voice coil welding point, and do not need the first gluing module 2 to perform secondary gluing. In this way, the first gluing module 2 and the second gluing module 5 can respectively perform synchronous gluing in the voice coil of the speaker to be capped corresponding to the second working position and the fourth working position, thereby reducing the operating time of the second gluing module 5, and avoiding the long operating time of a single station causing other modules to wait and reduce production capacity.

[0048] The above-mentioned preset position is preferably the gluing position of the second gluing module 5, so that when the capped speaker enters the fourth working position, the second gluing module 5 can directly apply the insulating glue, and the second gluing module 5 does not need to be moved and adjusted, which can effectively shorten the operation time.

[0049] In particular, the above-mentioned first working position, second working position, third working position and fourth working position are arranged along the running direction of the transfer module 4, and each positioning carrier 401 is transferred to the first working position, the second working position, the fourth working position and the third working position in sequence by the transfer module 4, that is, the speaker to be capped on each positioning carrier 401 first arrives at the first working position, and is adjusted by the adjustment module 1 so that the voice coil welding point of the speaker to be capped is located at a preset position, and then is driven to be transferred to the second working position by the transfer module 4, and the first gluing module 2 applies adhesive glue to the voice coil of the speaker to be capped, and then is driven to be transferred to the fourth working position by the transfer module 4, and the second gluing module 5 applies insulating glue at the voice coil welding point of the speaker to be capped, and finally is driven to be transferred to the third working position by the transfer module 4, and the capping module 3 installs the speaker cap into the voice coil of the speaker to be capped, thereby completing the capping manufacturing of the speaker to be capped.

[0050] Combination Figure 2 As shown, in another embodiment of the present invention, each positioning carrier 401 is rotatably mounted on the transfer module 4, and at least a portion of each positioning carrier 401 is exposed outside the transfer module 4, so as to facilitate connection with the positioning carrier 401, thereby realizing the rotation drive of the positioning carrier 401 and the speaker to be capped. In practical applications, each positioning carrier 401 is preferably mounted on the transfer module 4 through a bearing 42, which has a simple and practical structure and can reliably ensure that the positioning carrier 401 rotates on the transfer module 4. Of course, the specific installation method of each positioning carrier 401 on the transfer module 4 can be determined according to actual conditions.

[0051] Specifically, the above-mentioned adjustment module 1 includes a detection mechanism 11 and a first driving mechanism 12. The detection mechanism 11 includes a first sensor 111 (such as a photoelectric sensor, a visual sensor, etc.) corresponding to the top of the first working position, and the first sensor 111 is connected to the first driving mechanism 12 signal. Therefore, the first driving mechanism 12 can drive the positioning carrier 401 according to the detection signal of the first sensor 111, so that the voice coil welding point of the speaker to be capped on the positioning carrier 401 reaches and is located at a preset position.

[0052] The detection position of the first sensor 111 may specifically correspond to the preset position, so that when the voice coil soldering point of the speaker to be capped reaches the preset position through the drive of the first driving mechanism 12, the first sensor 111 will be triggered. When the first driving mechanism 12 receives the trigger signal of the first sensor 111, it stops driving the positioning carrier 401, so that the voice coil soldering point of the speaker to be capped is located at the preset position. Of course, in actual applications, the first sensor 111 can also be connected to the second glue module 5 signal, so that the second glue module 5 can obtain the position information of the voice coil soldering point of the speaker to be capped according to the detection signal of the first sensor 111, so as to adjust the position to apply insulating glue at the voice coil soldering point of the speaker to be capped.

[0053] Combination Figure 3 As shown, the first driving mechanism 12 comprises a first telescopic cylinder 121, a first motor 122 and a first roller 123, wherein the first roller 123 is mounted and fixed to the output shaft of the first motor 122, so that the first roller can be driven to rotate by the first motor 122. The first motor 122 is mounted and fixed to the output end of the first telescopic cylinder 121, and the first motor 122 and the first roller 123 are driven by the first telescopic cylinder 121 to perform telescopic movement toward the first working position.

[0054] In addition, the first roller 123 is driven by the first telescopic cylinder 121 to move toward the first working position, and is pressed against the positioning carrier 401 corresponding to the first working position (specifically, the portion of the first positioning carrier 401 exposed from the transfer module 4), and is driven to rotate by the first motor 122, thereby driving the positioning carrier 401 to rotate, thereby adjusting the position of the voice coil welding point of the speaker to be capped on the positioning carrier 401, until the voice coil welding point of the speaker to be capped reaches the preset position and triggers the first sensor 111. At this time, the first motor 122 stops driving the first roller, so that the voice coil welding point of the speaker to be capped corresponds to the preset position, and finally the first telescopic cylinder 121 drives the first motor 122 and the first roller 123 to retreat to disengage from the positioning carrier 401 to avoid affecting the operation of the transfer module 4.

[0055] The first roller 123 is preferably made of a colloid material (such as colloid), which allows the first roller 123 to have a greater friction force, thereby being able to reliably drive the positioning vehicle 401 to rotate, thereby preventing the first roller 123 from slipping and causing the positioning vehicle 401 to fail to adjust the position of the speaker to be capped.

[0056] To ensure that the first roller 123 can smoothly drive the positioning carrier 401, the first motor 122 is preferably installed at the output end of the first telescopic cylinder 121 in such a manner that the axial direction of the first roller 123 is parallel to the axial direction of the positioning carrier 401. Furthermore, the first roller 123 and the positioning carrier 401 can be located in the same plane, so that the first roller 123 can be reliably pressed against the outer peripheral surface of the positioning carrier 401.

[0057] Combination Figure 4As shown, the first gluing module 2 includes a second driving mechanism 21, a first transfer mechanism 22 and a first gluing device 23. The first gluing device 23 is mounted on the first transfer mechanism 22 and driven by the first transfer mechanism 22 to be transferred to the top of the second working position so as to apply adhesive glue inside the voice coil of the speaker to be capped at the second working position. In the process of applying adhesive glue by the first gluing device 23, the second driving mechanism 21 drives the positioning carrier 401 to rotate to move the speaker to be capped, so that the first gluing device 23 applies a circular glue layer inside the voice coil of the speaker to be capped, which is adapted to the shape and size of the speaker cap, so that when the capping module 3 installs the speaker cap into the voice coil, the glue layer can be bonded to the entire periphery of the speaker cap, thereby improving the connection strength between the speaker cap and the voice coil of the speaker to be capped and ensuring the bonding effect of the speaker cap. Of course, in actual applications, the shape and size of the glue layer applied by the first gluing module 2 inside the voice coil can be adjusted according to actual conditions.

[0058] In order to simplify the structural design and improve the consistency of the structural design, the second driving mechanism 21 can be configured in the same manner as the first driving mechanism 12. For example, the second driving mechanism 21 includes a second telescopic cylinder 211, a second motor 212, and a second roller 213, and the second roller 213 is mounted and fixed to the output shaft of the second motor 212, and the second motor 212 is mounted and fixed to the output end of the second telescopic cylinder 211 in such a manner that the axial direction of the second roller 213 is parallel to the axis of the positioning carrier 401, so that the second roller 213 can be driven by the second telescopic cylinder 211 to be pressed against the positioning carrier 401 corresponding to the second working position, and then driven to rotate by the second motor 212 to drive the positioning carrier 401 and the speaker cap to rotate, so that the first glue-spraying device 23 applies a circular glue layer in the voice coil of the speaker to be capped.

[0059] In particular, the first transfer mechanism 22 includes a sixth telescopic cylinder 221 arranged vertically, and the first glue device 23 is installed at the output end of the sixth telescopic cylinder 221. When the first glue device 23 performs the glue application operation, the sixth telescopic cylinder 221 extends to move the first glue device 23 downward, so as to shorten the distance between the output port of the first glue device 23 and the voice coil of the speaker to be capped, so that the adhesive can be reliably applied to the voice coil of the speaker to be capped. In addition, the first glue device 23 is raised by the sixth telescopic cylinder 221 to increase the distance between the first glue device 23 and the transfer module 4, which plays a role in avoiding air, can prevent the operation of the transfer module 4 from being obstructed, and is conducive to the annular transformation of the transfer module 4, and improves compatibility to be compatible with speakers of different sizes to be capped, and avoids the speaker to be capped from protruding from the transfer module 4 to a large height and easily colliding with the first glue device 23.

[0060] Combination Figure 5As shown, the second glue-spraying module 5 includes a third driving mechanism 53, a second transfer mechanism 51, and a plurality of second glue-spraying devices 52 mounted on the second transfer mechanism 51, and the plurality of second glue-spraying devices 52 are driven to the top of the fourth working position by the second transfer mechanism 51, and apply insulating glue to the voice coil welding point of the speaker to be capped at the fourth working position to complete the glue-spraying manufacturing at the voice coil welding point of the speaker to be capped. In addition, during the process of the second glue-spraying device 52 applying glue to the voice coil welding point of the speaker to be capped, the third driving mechanism 53 drives the positioning carrier of the fourth working position to rotate to increase the glue-spraying range of the second glue-spraying device 52, thereby ensuring that the second glue-spraying device can reliably apply insulating glue to the voice coil welding point and increase the product yield.

[0061] In practical applications, the number of the second glue applying devices 52 can be determined according to actual conditions. Since the speaker to be capped has two voice coil welding points, three second glue applying devices 52 can also be provided to increase the glue application range, thereby ensuring that the two voice coil welding points of the speaker to be capped can be covered with insulating glue.

[0062] In particular, the second transfer mechanism 51 includes a seventh telescopic cylinder arranged vertically, and the first glue device 23 is installed at the output end of the seventh telescopic cylinder. When the second glue device 52 is performing the glue coating operation, the seventh telescopic cylinder extends to move the second glue device 52 downward, thereby shortening the distance between the output port of the second glue device 52 and the voice coil welding point, so that the insulating glue can be reliably coated on the voice coil welding point, improving the accuracy of the glue coating operation, and ensuring the glue coating effect of the voice coil welding point. In addition, since the seventh telescopic cylinder retracts and raises the second glue device 52, the distance between the second glue device 52 and the transfer module 4 can be increased, which plays a role in avoiding air, can prevent the operation of the transfer module 4 from being obstructed, and is conducive to the modification of the transfer module 4, and improves compatibility, so as to be compatible with the capping manufacturing of speakers to be capped of different sizes, and avoid the speakers to be capped from protruding from the transfer module 4 at a large height and easily colliding with the second glue device 52.

[0063] The second gluing device 52 is preferably installed on the second transferring mechanism 51 through an adjusting plate. The adjusting plate is provided with a long hole arranged along a preset direction, and the second gluing device 52 can be locked on the adjusting plate by a bolt passing through the long hole. In this way, the gluing position of the second gluing device 52 can be adjusted to correspond to the preset position by changing the position of the bolt in the long hole, while improving compatibility. The position of the second gluing device 52 can be adjusted to adapt to speakers to be capped of different sizes (the positions of the voice coil welding points of speakers to be capped of different sizes are not the same).

[0064] Specifically, the second transfer mechanism 51 includes an X-axis transfer device 511, a Y-axis transfer device 512, and a Z-axis transfer device 513, and a plurality of second glue-applying devices 52 are mounted on the Z-axis transfer device 513, and the height positions of the plurality of second glue-applying devices 52 are adjusted by the Z-axis transfer device 513. In addition, the Z-axis transfer device 513 is mounted on the Y-axis transfer device 512, and the Y-axis transfer device 512 is mounted on the X-axis transfer device 511, and the transfer directions of the X-axis transfer device 511 and the Y-axis transfer device 512 are both arranged horizontally, so that the X-axis transfer device 511 and the Y-axis transfer device 512 can be driven to adjust the positions of the Z-axis transfer device 513 and the plurality of second glue-applying devices 52 in the horizontal direction, thereby realizing the three-axis drive transfer of the second glue-applying device 52, so that the second glue-applying device 52 corresponds to the fourth working position.

[0065] Of course, in actual applications, the assembly method between the X-axis transfer device 511, the Y-axis transfer device 512 and the Z-axis transfer device 513 can be adjusted according to actual conditions. For example, several gluing devices are installed on the Y-axis transfer device 512, the Y-axis transfer device 512 is installed on the Z-axis transfer device 513, and the Z-axis transfer device 513 is installed on the X-axis transfer device 511.

[0066] In actual applications, the X-axis transfer device 511, the Y-axis transfer device 512 and the Z-axis transfer device 513 of the present embodiment are all manually driven. During the debugging process of the automatic speaker capping equipment, the X-axis transfer device 511, the Y-axis transfer device 512 and the Z-axis transfer device 513 are manually driven so that the second gluing device 52 corresponds to the preset position to accurately apply glue to the voice coil welding points of the speaker to be capped.

[0067] In order to further simplify the structural design, improve the consistency of the structural design and reduce the types of materials, the third driving mechanism 53 can be arranged in the same manner as the first driving mechanism 12 and the second driving mechanism 13. For example, the third driving mechanism 53 includes a third telescopic cylinder 531, a third motor 532 and a third roller 533, the third roller 533 is fixed to the output shaft of the third motor 532, and the third motor 532 is fixed to the output end of the third telescopic cylinder 531 in a manner that the axial direction of the third roller 533 is parallel to the axial direction of the positioning carrier 401, so that the third roller 533 can be driven by the third telescopic cylinder 531 to be pressed against the positioning carrier 401 corresponding to the fourth working position, and then driven to rotate by the third motor 532 to drive the positioning carrier 401 and the speaker cap to rotate, so that the second glue device 52 is coated with a semicircular or circular glue layer at the voice coil welding point of the speaker to be capped to increase the glue coating area. Of course, in actual applications, the shape of the glue layer can be determined according to actual conditions, such as a third of a circular ring, a quarter of a circular ring, etc.

[0068] Combination Figure 6 As shown, in one embodiment of the present invention, the capping module 3 includes a speaker cap material bin 31, a material dividing mechanism 32 and a capping mechanism 33, wherein the speaker cap material bin 31 is detachably mounted on the material dividing mechanism 32, and two adjacent speaker caps in the speaker cap material bin 31 are separated from each other under the action of the material dividing mechanism 32, so as to avoid the two adjacent speaker caps from fitting together and being loaded into the voice coil of the speaker to be capped by the capping device, thereby effectively reducing the product defective rate.

[0069] The above-mentioned capping mechanism 33 includes a third transferring mechanism 331 and a suction cup device 332 installed on the third transferring mechanism 331. The suction cup device 332 is transferred into the speaker cap material bin 31 through the third transferring mechanism 331, and adsorbed to the speaker cap in the speaker cap material bin 31, and then transferred through the third transferring mechanism 331. The speaker cap adsorbed on the suction cup device 332 can be transferred and loaded into the voice coil of the speaker to be capped corresponding to the third working position, thereby completing the assembly operation of the speaker cap.

[0070] In order to prevent two adjacent speaker caps from fitting together and being installed together into the voice coil of the speaker to be capped, a vibration design can be performed on the third transfer mechanism 331, so that the two speaker caps that fit together can be separated by vibration. For example, the third transfer mechanism 331 includes a transfer device 3311 and a fourth telescopic cylinder 3312, the fourth telescopic cylinder 3312 is installed on the transfer device 3311, and the suction cup device 332 is installed and fixed at the output end of the fourth telescopic cylinder 3312, so that the fourth telescopic cylinder 3312 can perform repeated telescopic operations after the suction cup device 332 absorbs the speaker cap, thereby vibrating the suction cup device 332 and the speaker cap, and preventing the suction cup device 332 from simultaneously absorbing two or more speaker caps.

[0071] Furthermore, the material dividing mechanism 32 includes a lifting assembly 321, a fifth telescopic cylinder 322 and two material dividing blocks 323. The two material dividing blocks 323 are mounted to the output end of the fifth telescopic cylinder 322 via a connecting piece 324, so that the two material dividing blocks 323 can be driven and transferred by the fifth telescopic cylinder 322. In particular, the two material dividing blocks 323 can be assembled to the output end of the fifth telescopic cylinder 322 via a sheet metal part.

[0072] Moreover, a material dividing cavity matching the shape and size of the trumpet cap is formed between the two material dividing blocks 323, and the material dividing cavity is driven by the fifth telescopic cylinder 322 so that the material dividing cavity corresponds to the opening of the material taking port of the trumpet cap material bin 31, so that the suction cup device 332 needs to be inserted into the trumpet cap material bin 31 through the material dividing cavity, that is, the trumpet cap sucked out by the suction cup device 332 will pass through the material dividing cavity. In particular, the inner wall of the above-mentioned material dividing cavity is provided with a thread structure, and because the shape and size of the material dividing cavity are matched with the shape and size of the trumpet cap, the thread structure will rub the outer edge of the trumpet cap when the trumpet cap passes through the material dividing cavity, thereby separating the two adjacent trumpet caps, achieving the material dividing function, and preventing the two adjacent trumpet caps from fitting together.

[0073] The above-mentioned material dividing mechanism 32 is provided with two material dividing blocks 323, and the two material dividing blocks 323 enclose a material dividing cavity, so that the size of the material dividing cavity can be adjusted by changing the distance between the two material dividing blocks 323, thereby adapting to horn caps of different sizes and improving compatibility. In addition, since the two material dividing blocks 323 are driven to correspond to the horn cap material bin 31 by the fifth telescopic cylinder 322, when the horn cap material bin 31 needs to be replaced, the replacement operation of the horn cap material bin 31 can be implemented by only driving the fifth telescopic cylinder 322 to drive the two material dividing blocks 323 to retract.

[0074] In another embodiment of the present invention, the above-mentioned lifting assembly 321 includes a fourth motor 3211, a transmission device 3212, a lifting rod 3213 and a second sensor 3214. The second sensor 3214 is connected to the fourth motor 3211 signal, and the detection position of the second sensor 3214 corresponds to the material picking position of the suction cup device 332 (the suction cup device 332 is inserted into the horn cap silo 31 and adsorbs the horn cap at the material picking position). Therefore, when the horn cap in the horn cap silo 31 is at the material picking position, the second sensor 3214 will be triggered, so that the second sensor 3214 sends a trigger signal to the fourth motor 3211.

[0075] Furthermore, the fourth motor 3211 is connected to the transmission device 3212, and the lifting rod 3213 is fixedly connected to the transmission device 3212, and the lifting rod 3213 is inserted into the horn cap silo 31 from the end of the horn cap silo 31 away from the material taking port, thereby ensuring that the horn cap in the horn cap silo 31 can be pushed toward the material taking position.

[0076] Specifically, the transmission device 3212 drives the lifting rod 3213 to move under the drive of the fourth motor 3211, so as to drive the lifting rod 3213 to push the horn cap in the horn cap bin 31, and when the horn cap reaches the material taking position, the fourth motor 3211 receives the trigger signal of the second sensor 3214 and stops driving the transmission device 3212 and the lifting rod 3213, so as to ensure that the suction cup device 332 can be adsorbed to the horn cap at the material taking position. In actual application, when the horn cap at the material taking position is sucked away by the suction cup device 332, the second sensor 3214 is not triggered, and the fourth motor 3211 starts and drives the transmission device 3212 and the lifting rod 3213 to move, so as to push the horn cap to the material taking position, thereby realizing automatic loading of the horn cap.

[0077] The structural design of the transmission device 3212 can be specifically determined according to actual conditions. For example, the transmission device 3212 includes a first guide rail, a screw member and a screw nut mounted on the screw member, the screw nut is connected to a first slider mounted on the first guide rail, so that the first guide rail and the first slider cooperate to improve the stability and reliability of the movement of the screw nut; and the fourth motor 3211 is fixedly connected to the screw member, and the lifting rod 3213 is fixedly connected to the screw nut, so that the screw member can drive the screw nut and the lifting rod 3213 to move along the length direction of the screw member under the drive of the fourth motor 3211. In order to ensure that the lifting rod 3213 can reliably lift the horn cap in the horn cap bin 31, the lifting rod 3213 and the screw member are preferably arranged along the axial direction of the horn cap bin 31.

[0078] Combination Figure 7 As shown, the above-mentioned speaker automatic capping equipment also includes a blanking module 6 and a fifth working position formed on the transfer module 4, and the blanking module 6 corresponds to the fifth working position, and is used to transfer the speaker equipped with the speaker cap on the positioning carrier 401 corresponding to the fifth working position to the finished product area, thereby realizing the blanking operation.

[0079] Of course, in practical applications, the structural design of the unloading module 6 can be specifically determined according to actual conditions; for example, the unloading module 6 includes a fourth transfer mechanism 61 and a mechanical gripper 62. The mechanical gripper 62 transfers and grabs the speaker with the speaker cap located at the fifth working position through the fourth transfer mechanism 61, and then transfers the speaker with the speaker cap to the finished product area through the fourth transfer mechanism 61.

[0080] In particular, the fourth transfer mechanism 61 of the present embodiment includes a support frame 611, a fifth motor 612, a synchronous belt device, and a second guide rail 615 and a second slider 616 that are connected together, and the mechanical gripper 62 is mounted on the support frame 611 in a manner that it can slide along the length direction of the second guide rail 615 by being fixed to the second slider 616. In addition, the synchronous belt device includes two synchronous wheels 613 rotatably mounted on the support frame 611, and a synchronous belt 614 adjusted on the two synchronous wheels 613, and the fifth motor 612 is connected to one of the synchronous wheels 613, and the synchronous belt 614 is fixedly connected to the mechanical gripper 62 through a transmission member, so when the fifth motor 612 drives the synchronous wheel 613 to rotate, the synchronous belt 614 runs synchronously and drives the mechanical gripper 62 to slide along the length direction of the second guide rail 615, thereby realizing the transfer operation of the mechanical gripper 62. The above structure is simple and practical, and the fourth transfer mechanism 61 adopts a synchronous belt device to effectively improve the transfer efficiency, thereby achieving efficient material unloading, saving time and improving production capacity.

[0081] In one embodiment of the present invention, the transfer module 4 includes a turntable 41 and a driving device, and a plurality of positioning carriers 401 are evenly distributed along the circumference of the turntable 41, and the first working position, the second working position, the fourth working position, the third working position, and the fifth working position are respectively distributed around the turntable 41, and the distance between the first working position, the second working position, the fourth working position, the third working position, and the fifth working position is adapted to the distance between two adjacent positioning carriers 401, ensuring that the transfer module 4 can synchronously transfer part of the positioning carriers 401 to the first working position, the second working position, the fourth working position, the third working position, and the fifth working position to perform related capping operations at the same time, avoiding the module from waiting for a long time and extending the capping manufacturing cycle. In practical applications, the structural design of the above-mentioned driving device can be specifically determined according to actual conditions, and it is preferred to use a cam divider in conjunction with a motor to complete the drive of the turntable 41.

[0082] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
