In practical applications, each positioning carrier 401 is preferably mounted on the transferring module 4 through the bearing 42, so that the structure is simple and practical, and the positioning carrier 401 can be reliably ensured to rotate on the transferring module 4. Of course, the installation manner of each positioning carrier 401 on the transferring module 4 can be determined according to actual situations.

Specifically, the adjusting module 1 includes a detecting mechanism 11 and a first driving mechanism 12, the detecting mechanism 11 includes a first sensor 111 (e.g., a photoelectric sensor, a vision sensor, etc.) corresponding to the upper side of the first working position, and the first sensor 111 is in signal connection with the first driving mechanism 12, so that 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 solder joint of the to-be-covered speaker on the positioning carrier 401 reaches and is located at a preset position.

Of course, in practical applications, the shape and size of the glue layer coated in the voice coil by the first glue applying module 2 can be adjusted according to practical situations.

In order to simplify the structure and improve the consistency of the structure, the second driving mechanism 21 may be the same 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 installed and fixed to an output shaft of the second motor 212, and the second motor 212 is installed and fixed to an output end of the second telescopic cylinder 211 in a manner that an axial direction of the second roller 213 is parallel to an axis of the positioning carrier 401, so that the second roller 213 can be driven by the second telescopic cylinder 211 to adhere to the positioning carrier 401 corresponding to the second working position, and then driven by the second motor 212 to rotate so as to drive the positioning carrier 401 and the speaker cap to rotate, so that the first glue applying device 23 applies a circular glue layer in the voice coil of the speaker to be capped.

Particularly, the first transfer mechanism 22 includes a sixth telescopic cylinder 221 arranged vertically, and the first glue applying device 23 is installed at the output end of the sixth telescopic cylinder 221, when the first glue applying device 23 performs a glue applying operation, the sixth telescopic cylinder 221 extends out to transfer the first glue applying device 23 downwards, so as to shorten the distance between the output port of the first glue applying device 23 and the voice coil of the to-be-capped speaker, so that the adhesive can be reliably applied to the voice coil of the to-be-capped speaker. In addition, the sixth telescopic cylinder 221 retracts to lift the first gluing device 23, so that the distance between the first gluing device 23 and the transferring module 4 can be increased, a space avoidance effect is achieved, the moving of the transferring module 4 can be prevented from being obstructed, the annular transformation of the transferring module 4 is facilitated, the compatibility is improved, the horn-shaped cover cap is compatible with the horn-shaped cover cap to be covered, which has different sizes, and the horn-shaped cover cap is prevented from protruding out of the transferring module 4, so that the height of the horn-shaped cover cap is large and the horn-shaped cover cap is easy to collide with the first gluing device 23.

In addition, in the process that the second gluing device 52 applies 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, so that the gluing range of the second gluing device 52 is enlarged, the second gluing device can be ensured to lean against the voice coil welding point to apply insulating glue, and the product yield is increased.

In practical applications, the number of the second glue applying devices 52 may be determined according to practical situations. Because the to-be-capped loudspeaker is provided with two voice coil welding spots, three second gluing devices 52 can be arranged to enlarge the gluing range, so that the two voice coil welding spots of the to-be-capped loudspeaker can be covered by the insulating glue.

Particularly, the second transfer mechanism 51 includes a seventh telescopic cylinder vertically arranged, the first glue applying device 23 is installed at the output end of the seventh telescopic cylinder, when the second glue applying device 52 performs a glue applying operation, the seventh telescopic cylinder extends out to downwardly transfer the second glue applying device 52, so that the distance between the output port of the second glue applying device 52 and a welding point of the voice coil is shortened, the insulating glue can be reliably applied to the welding point of the voice coil, the accuracy of the glue applying operation is improved, and the glue applying effect of the welding point of the voice coil is ensured. Moreover, as the seventh telescopic cylinder retracts to raise the second glue applying device 52, the distance between the second glue applying device 52 and the transfer module 4 can be increased, a clearance avoiding effect is achieved, not only can the operation of the transfer module 4 be prevented from being hindered, but also the model changing transformation of the transfer module 4 is facilitated, the compatibility is improved, the cap manufacturing of the to-be-capped horn with different sizes is compatible, and the problem that the to-be-capped horn protrudes to transfer the module 4, so that the height of the to-be-capped horn is large and the to-be-capped horn easily collides with the second glue applying device 52 is avoided.

The second is beaten mucilage binding and is put 52 preferably to install the second through the regulating plate and move and carry mechanism 51 on, the regulating plate is equipped with the rectangular hole that sets up along the direction of predetermineeing, and the second is beaten mucilage binding and is put 52 accessible and pass the bolt locking in this rectangular hole on the regulating plate, can adjust the second through changing the position of bolt in rectangular hole and beat the rubber coating position of mucilage binding 52 like this, in order to correspond to predetermineeing the position, can improve compatibility again simultaneously, beat the position of mucilage binding and put 52 with the adaptation in not unidimensional treating the block loudspeaker (the position of the voice coil loudspeaker voice coil solder joint of treating the block loudspeaker of not unidimensional is different the same through the adjustment second.

Referring to fig. 6, in an embodiment of the present invention, the capping module 3 includes a speaker cap bin 31, a material distribution mechanism 32 and a capping mechanism 33, wherein the speaker cap bin 31 is detachably mounted on the material distribution mechanism 32, and two adjacent speaker caps in the speaker cap bin 31 are separated from each other under the action of the material distribution mechanism 32, so as to prevent the two adjacent speaker caps from being attached to each other and being mounted in a voice coil of a speaker to be capped by a capping device, thereby effectively reducing the fraction defective of the product.

The cap mechanism 33 includes a third transfer mechanism 331 and a suction cup device 332 installed on the third transfer mechanism 331, the suction cup device 332 is transferred to the horn cap bin 31 through the third transfer mechanism 331 and is adsorbed to the horn cap in the horn cap bin 31, and then the third transfer mechanism 331 is used for transferring, so that the horn cap adsorbed on the suction cup device 332 can be transferred and installed into the voice coil of the horn to be capped corresponding to the third working position, and the assembling operation of the horn cap is completed.

The two adjacent horn caps are prevented from being attached to each other to be mounted together in the voice coil of the horn to be capped, so that the third transfer mechanism 331 can be subjected to vibration design, and the two horn caps attached to each other can be separated from each other through vibration. For example, the third transfer mechanism 331 includes a transfer unit 3311 and a fourth telescopic cylinder 3312, the fourth telescopic cylinder 3312 is installed on the transfer unit 3311, and the chuck device 332 is installed and fixed to an output end of the fourth telescopic cylinder 3312, so that the chuck device 332 and the horn cap are vibrated by repeating the telescopic operation after the chuck device 332 sucks the horn cap by the fourth telescopic cylinder 3312, thereby preventing the chuck device 332 from sucking two or more horn caps at the same time.

Further, the material distribution mechanism 32 includes a jacking assembly 321, a fifth telescopic cylinder 322 and two material distribution blocks 323, and the two material distribution blocks 323 are mounted to the output end of the fifth telescopic cylinder 322 through a connecting member 324, so that the two material distribution blocks 323 can be driven and moved by the fifth telescopic cylinder 322. In particular, two distributor blocks 323 may be assembled to the output end of the fifth telescopic cylinder 322 by sheet metal parts.

Moreover, a material distributing cavity matched with the shape and size of the horn cap is formed between the two material distributing blocks 323, and the material distributing cavity is driven by the fifth telescopic cylinder 322 to correspond to the opening of the material taking port of the horn cap bin 31, so that the suction cup device 332 needs to be inserted into the horn cap bin 31 through the material distributing cavity, that is, the horn cap sucked out through the suction cup device 332 passes through the material distributing cavity. Particularly, the inner wall of the material distribution cavity is provided with a thread structure, and the shape and the size of the material distribution cavity are matched with those of the horn caps, so that the thread structure can rub the outer edges of the horn caps when the horn caps pass through the material distribution cavity, the adjacent two horn caps are separated, the material distribution function is achieved, and the adjacent two horn caps are prevented from being attached to each other.

The material distributing mechanism 32 is provided with the two material distributing blocks 323, and the two material distributing blocks 323 surround to form the material distributing cavity, so that the size of the material distributing cavity can be adjusted by changing the distance between the two material distributing blocks 323, the material distributing mechanism is further adapted to horn caps with different sizes, and the compatibility is improved. Moreover, since the two distributing blocks 323 are driven by the fifth telescopic cylinder 322 to correspond to the horn cap storage bin 31, when the horn cap storage bin 31 needs to be replaced, the replacing operation of the horn cap storage bin 31 can be implemented only by driving the two distributing blocks 323 to retreat by the fifth telescopic cylinder 322.

In another embodiment of the present invention, the jacking assembly 321 includes a fourth motor 3211, a transmission device 3212, a jacking rod 3213, and a second sensor 3214, the second sensor 3214 is in signal connection with the fourth motor 3211, and a detection position of the second sensor 3214 corresponds to a material taking position of the suction cup device 332 (the suction cup device 332 is inserted into the horn cap storage bin 31, and adsorbs the horn cap at the material taking position), so that the second sensor 3214 is triggered when the horn cap in the horn cap storage bin 31 is at the material taking position, so that the second sensor 3214 sends a trigger signal to the fourth motor 3211.

Further, the fourth motor 3211 is connected to the transmission device 3212, the lifting rod 3213 is fixedly connected to the transmission device 3212, and the lifting rod 3213 is inserted into the horn cap bin 31 from an end of the horn cap bin 31 away from the material taking port, so as to ensure that the horn cap in the horn cap bin 31 is pushed toward the material taking position.

Specifically, the transmission device 3212 drives the jacking rod 3213 to move under the driving of the fourth motor 3211, so as to drive the jacking 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 jacking rod 3213, thereby ensuring that the suction cup device 332 can be adsorbed to the horn cap at the material taking position. In practical application, after the loudspeaker cap at the material taking position is sucked away by the sucking disc device 332, the second sensor 3214 is not triggered, and the fourth motor 3211 is started and drives the transmission device 3212 and the jacking rod 3213 to move, so that the loudspeaker cap is pushed to the material taking position, and automatic feeding of the loudspeaker cap is realized.

For example, the transmission device 3212 includes a first guide rail, a screw member, and a screw nut installed on the screw member, the screw nut is connected to a first slider installed on the first guide rail, so that the first guide rail and the first slider cooperate to improve the stability and reliability of movement of the screw nut; further, since the fourth motor 3211 is fixedly connected to the screw member and the lifting rod 3213 is fixedly connected to the screw nut, the screw member can drive the screw nut and the lifting rod 3213 to move in the longitudinal direction of the screw member by the driving of the fourth motor 3211. To ensure that the jacking rod 3213 can reliably jack the horn cap in the horn cap storage bin 31, the jacking rod 3213 and the screw member are preferably arranged along the axial direction of the horn cap storage bin 31.

As shown in fig. 7, the automatic horn capping device further includes a blanking module 6 and a fifth work station formed on the transfer module 4, and the blanking module 6 corresponds to the fifth work station and is configured to transfer the horn with the horn cap on the positioning carrier 401 corresponding to the fifth work station to the finished product area, thereby achieving the blanking operation.

Certainly, in practical application, the structural design of the blanking module 6 can be specifically determined according to practical conditions; for example, the blanking module 6 includes a fourth transfer mechanism 61 and a mechanical gripper 62, the mechanical gripper 62 transfers and grips the horn with the horn cap at the fifth work position by the fourth transfer mechanism 61, and then transfers the horn with the horn cap to the finished product area by the fourth transfer mechanism 61.

Specifically, the fourth transfer mechanism 61 of the present embodiment includes a support frame 611, a fifth motor 612, a timing belt device, and a second rail 615 and a second slider 616 that are cooperatively connected together, and the mechanical gripper 62 is fixed to the support frame 611 by being fixed to the second slider 616 so as to be slidable in the longitudinal direction of the second rail 615. In addition, the synchronous belt device includes two synchronizing wheels 613 rotatably mounted to the supporting frame 611, and a synchronous belt 614 adjusted on the two synchronizing wheels 613, and the fifth motor 612 is connected to one of the synchronizing wheels 613, and the synchronous belt 614 is fixedly connected to the mechanical gripper 62 through a transmission member, so that when the fifth motor 612 drives the synchronizing wheels 613 to rotate, the synchronous belt 614 synchronously runs and drives the mechanical gripper 62 to slide along the length direction of the second guide rail 615, thereby implementing the transferring operation of the mechanical gripper 62. The structure is simple and practical, and the fourth transfer mechanism 61 can effectively improve the transfer efficiency by adopting the synchronous belt device, thereby realizing high-efficiency blanking and saving time to improve productivity.
