Detailed Embodiment

[0061] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0062] As Figures 1 to 8 shown, the encapsulation device for producing head-mounted bone conduction headphones of the present utility model includes:

[0063] A support table 1, which is independently and fixedly arranged;

[0064] A turntable 2, which is rotatably arranged on the support table 1 and is used for transporting the headphones. Four positioning components 21 are arranged in a circumferential arrangement on the turntable 2;

[0065] An adjusting mechanism 3, which is arranged on the support table 1 and is used for adjusting the positioning component 21;

[0066] A self-rotation mechanism 4, which is arranged on the support table 1 and is used for driving the headphones to rotate self;

[0067] A loading and unloading mechanism 5, which is arranged on the support table 1 and is used for automatic loading and unloading;

[0068] A dispensing and encapsulation mechanism 6, which is fixedly installed on the support table 1 and is used for dispensing and encapsulating the headphones;

[0069] Among them, the self-rotation mechanism 4 further includes:

[0070] A plurality of workpiece pallets 41, which are arranged on the turntable 2 and are used for carrying the headphones; a positioning hole is arranged in the middle of the workpiece pallet 41, and the positioning component 21 is inserted into the positioning hole of the workpiece pallet 41 to position and fix the workpiece pallet 41;

[0071] A fixing tool 42, and four fixing tools 42 are rotatably arranged on each workpiece pallet 41;

[0072] A clamping groove 43, which is arranged at the bottom end of the fixing tool 42;

[0073] A plurality of driving rods 49, which are arranged on the support table 1 to slide up and down and rotate on the support table 1. A flat position is arranged at the top end of the driving rod 49, and the driving rod 49 is inserted into the clamping groove 43. The number of the driving rods 49 is equal to the number of the fixing tools 42;

[0074] The working process and principle of the device are as follows: The bone conduction headphones to be encapsulated are placed on the workpiece pallet 41 one by one, and then the workpiece pallet 41 carrying the headphones is placed on the turntable 2. The adjusting mechanism 3 adjusts the positioning component 21 to ensure that the positioning component 21 can accurately insert into the positioning holes of the workpiece pallet 41 to position and fix the workpiece pallet 41. The turntable 2 starts to rotate, transporting the workpiece pallet 41 to the lower part of the dispensing and encapsulation mechanism 6. At this time, the self-rotation mechanism 4 starts to work. The driving rod 49 slides up and down and rotates on the support table 1, and the flat part at its top is inserted into the card slot 43 at the bottom of the fixing tooling 42. As the driving rod 49 rotates, the fixing tooling 42 and the headphones start to rotate. At the same time, the dispensing and encapsulation mechanism 6 starts to work to perform all-round dispensing and encapsulation on the headphones. After the dispensing and encapsulation is completed, the self-rotation mechanism 4 stops working, and the driving rod 49 withdraws from the card slot 43. The turntable 2 continues to rotate, transporting the encapsulated headphones to the unloading station. The loading and unloading mechanism 5 works again to remove the encapsulated headphones and prepare for the next round of loading. The equipment works in a cycle according to the above working process to achieve continuous, efficient, and automated encapsulation of the head-mounted bone conduction headphones. The design of the self-rotation mechanism 4 enables the headphones to rotate during the encapsulation process, thereby achieving all-round dispensing. This ensures the uniformity and integrity of the encapsulation effect and improves the encapsulation quality of the product. The automated design of the equipment reduces manual operation and reduces the safety risks caused by improper operation. It improves the encapsulation efficiency and encapsulation quality, and also reduces the labor intensity and production safety risks.

[0075] Preferably, as in the above embodiment, the self-rotation mechanism 4 further includes:

[0076] A guiding and sliding support plate 44, fixedly installed on the support table 1;

[0077] A cylinder support 45, hoisted on the guiding and sliding support plate 44;

[0078] A second cylinder 46, fixedly installed on the cylinder support 45;

[0079] A lifting frame 47, slidably installed up and down on the guiding and sliding support plate 44, controlled to lift by the second cylinder 46, and a driving rod 49 is rotatably arranged on the lifting frame 47;

[0080] A first motor 48, fixedly installed on the lifting frame 47, used to drive each driving rod 49 to rotate;

[0081] When the earphone needs to be encapsulated with glue, the second air cylinder 46 starts, pushing the lifting frame 47 to move upward along the guiding support plate 44; as the lifting frame 47 rises, the driving rod 49 installed on it gradually approaches and finally inserts into the card slot 43 at the bottom end of the fixed tooling 42, achieving mechanical connection; the first motor 48 is started, and the driving rod 49 is driven to rotate through the transmission system; since the driving rod 49 is connected to the fixed tooling 42, this will cause the fixed tooling 42 and the earphone on it to rotate synchronously, ensuring that the earphone can rotate omnidirectionally within the processing area, so as to achieve uniform glue dispensing; after the glue dispensing is completed, the first motor 48 stops running, and the second air cylinder 46 acts again, causing the driving rod 49 to be withdrawn from the card slot 43 and disconnecting from the fixed tooling 42; by precisely controlling the rotational movement of the driving rod 49, it can ensure that the earphone is covered comprehensively and without dead angles during the glue dispensing process, improving the quality and consistency of the glue dispensing.

[0082] As a preference of the above embodiment, the positioning assembly 21 includes:

[0083] A fixed block 2a, fixedly installed on the turntable 2, and two sliding grooves are symmetrically arranged inside the fixed block 2a;

[0084] Two elastic springs 2b, respectively fixedly installed in the two sliding grooves inside the fixed block 2a;

[0085] Two guiding and pressing rods 2c, respectively slidably installed in the two sliding grooves and fixedly connected to the elastic springs 2b; when the guiding and pressing rods 2c extend, they will press on the workpiece supporting plate 41 to fix the workpiece supporting plate 41, and when the guiding and pressing rods 2c contract, they can lift the workpiece supporting plate 41 upward and remove it;

[0086] Two hinge shafts 2d, respectively fixedly installed on the two guiding and pressing rods 2c;

[0087] Two transmission pieces 2e, both swingably installed on the fixed block 2a, and the top ends of the transmission pieces 2e are hinged to the corresponding hinge shafts 2d, and the bottom of the transmission pieces 2e is provided with an inclined guide surface;

[0088] The working process and principle of the positioning component 21 are as follows: When it is necessary to place the workpiece pallet 41 on the turntable 2, the bottom of the transmission piece 2e is controlled to swing outwards, thereby driving the top end of the transmission piece 2e to swing inwards. Then, the guide slide rod 2c is driven by the hinge shaft 2d to slide inwards along the chute, and the elastic spring 2b is compressed; when the workpiece pallet 41 is completely placed on the fixed block 2a, the elastic spring 2b returns to its original state, pushing the guide slide rod 2c to extend outwards and pressing on the workpiece pallet 41 to achieve firm fixation of the workpiece pallet 41; when it is necessary to take out the workpiece pallet 41, similarly control the bottom of the transmission piece 2e to swing outwards, so that the guide slide rod 2c slides inwards along the chute, and then the workpiece pallet 41 can be lifted; through the cooperation of the elastic spring 2b and the guide slide rod 2c, firm fixation of the workpiece pallet 41 is achieved; by pushing the inclined plane of the transmission piece 2e through an external mechanism, the guide slide rod 2c can be conveniently contracted, so that the workpiece pallet 41 can be easily taken out; the operation process is simplified and the work efficiency is improved; the positioning component 21 improves the fixing stability and the taking-out convenience of the workpiece pallet 41.

[0089] As a preference of the above embodiment, the adjusting mechanism 3 includes:

[0090] An adjusting support 31, fixedly installed on the support table 1;

[0091] A guide slide base 32, fixedly installed on the adjusting support 31;

[0092] A first air cylinder 33, fixedly installed on the adjusting support 31;

[0093] A guide slide plate 34, slidably inserted into the guide slide base 32, and the bottom end thereof is fixedly connected to the top output end of the first air cylinder 33;

[0094] Two rollers 35, both rotatably installed on the guide slide plate 34, and the rollers 35 are arranged above the guide slide base 32;

[0095] The working process and principle of the adjusting mechanism 3 are as follows: When it is necessary to adjust the position of the positioning component 21, the first air cylinder 33 starts to work; its top output end extends out, pushing the guide slide plate 34 to slide upwards along the guide slide base 32; as the guide slide plate 34 rises, the rollers 35 also rise and gradually cooperate with the inclined plane at the bottom of the transmission piece 2e. Continuing to push the guide slide plate 34 upwards, a certain pressure can be exerted on the inclined plane at the bottom of the transmission piece 2e through the rollers 35, so that the bottom of the transmission piece 2e swings outwards, and then the guide slide rod 2c is automatically controlled to contract, so as to automatically complete the taking and placing functions of the workpiece pallet 41; improving the convenience of use.

[0096] As a preference of the above embodiment, the loading and unloading mechanism 5 includes:

[0097] A second motor 51, fixedly installed on the support table 1;

[0098] The third cylinder 52 is fixedly installed at the top of the second motor 51 and is driven to rotate by the second motor 51;

[0099] The lifting frame 53 is fixedly installed at the top of the third cylinder 52. The lifting frame 53 is set in an "L" shape and its vertical height is adjusted by the third cylinder 52;

[0100] Two clamping cylinders 54 are both fixedly installed on the lifting frame 53. Two clamping plates 55 are slidably arranged on each clamping cylinder 54, and a lifting hole is arranged on the clamping plate 55;

[0101] The lifting lugs 56, and two lifting lugs 56 are symmetrically and fixedly installed on each workpiece support plate 41;

[0102] The working process and principle of the loading and unloading mechanism 5 are as follows: When loading is required, the second motor 51 is started to drive the third cylinder 52 and the lifting frame 53 to rotate above the workpiece support plate 41 to be loaded; then, the third cylinder is controlled to lower the lifting frame 53 to an appropriate height so that the clamping plate 55 can approach the lifting lug 56 on the workpiece support plate 41; then, the clamping cylinder 54 is started to push the clamping plate 55 to move inwards until the lifting hole is aligned with and clamped to the lifting lug 56; at this time, the third cylinder 52 is started again to lift the lifting frame 53 to lift the workpiece support plate 41 and the earphones thereon; the lifting frame 53 and the clamped workpiece support plate 41 are controlled by the second motor 51 to rotate above the turntable 2, and the workpiece support plate 41 is placed below onto the turntable 2; the loading and unloading mechanism 5 realizes the automatic loading and unloading of the earphones through the coordinated work of the second motor 51, the third cylinder 52 and the clamping cylinder 54; it not only improves the production efficiency, but also reduces the difficulty and intensity of manual operation.

[0103] As a preference of the above embodiment, an exhaust hole is arranged on the lifting lug 56; when the clamping cylinder 54 of the loading and unloading mechanism 5 pushes the clamping plate 55 to clamp the lifting lug 56, if there is air or gas residue between the contact surface of the lifting lug 56 and the clamping plate 55, it will affect the clamping stability and accuracy; at this time, the exhaust hole on the lifting lug 56 can serve as a gas escape channel, so that the residual air or gas during the clamping process can be discharged smoothly, thereby ensuring that the clamping plate 55 can tightly and stably clamp the lifting lug 56, reducing the looseness and instability during the clamping process, and thus improving the clamping stability and accuracy.

[0104] As a preference of the above embodiment, the loading and unloading mechanism 5 further includes:

[0105] Two limit supports 5a are both fixedly installed on the second motor 51, and the included angle between the two limit supports 5a is a right angle;

[0106] Limit switches 5b, and one limit switch 5b is fixedly installed on each limit support 5a;

[0107] The limit plate 5c is fixedly installed on the hoisting frame 53 and positioned by the limit switch 5b. When loading and unloading are required, the second motor 51 starts, driving the third cylinder 52 and the hoisting frame 53 to rotate to the specified position. During this process, the limit plate 5c moves as the hoisting frame 53 rotates. When the hoisting frame 53 rotates to the predetermined angle, the limit plate 5c contacts the corresponding limit switch 5b, triggering the limit switch 5b. At this time, the second motor 51 receives the feedback signal from the limit switch 5b and stops rotating. After the hoisting frame 53 stops stably, the third cylinder 52 starts to act, adjusting the height of the hoisting frame 53 so that the clamping plate 55 can accurately clamp or release the lug 56, completing the loading and unloading operation. By the combined use of the limit support 5a, the limit switch 5b and the limit plate 5c, the rotation angle of the hoisting frame 53 can be accurately controlled, ensuring the accuracy during the loading and unloading process. Precise positioning and stable operation can shorten the loading and unloading time and improve production efficiency.

[0109] The loading conveyor belt 5d is fixedly installed on the support table 1 and is used to convey the un-dot-glued and encapsulated earphones.

[0110] The unloading conveyor belt 5e is fixedly installed on the support table 1 and is used to receive the earphones after dot-gluing and encapsulation are completed and convey them outwards. The loading conveyor belt 5d can successively and continuously convey the workpiece pallets 41 carrying the un-dot-glued and encapsulated earphones to the specified position, and the unloading conveyor belt 5e can successively and continuously convey the workpiece pallets 41 carrying the earphones after dot-gluing and encapsulation are completed to the next processing station. The continuous conveying function of the loading conveyor belt 5d and the unloading conveyor belt 5e enables the earphones to enter and leave the equipment continuously, thereby improving production efficiency.

[0111] For the encapsulation equipment for producing the head-worn bone conduction earphones of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out.
