[0036] This invention provides an automated assembly line for headphone cases, which enables automated and continuous assembly of headphone cases and improves assembly efficiency.

[0037] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Please refer to Figure 1 , Figure 1 An automatic assembly production line for an earphone box provided in this embodiment of the invention includes a base, and two double-speed chain conveyors 100 disposed on the base, the two double-speed chain conveyors 100 being arranged in parallel on the base.

[0040] Lifting mechanisms 1 for loading and unloading are respectively provided at the loading end and the unloading end of the double-speed chain conveyor 100. Along the loading end to the unloading end, the following are arranged in sequence: folding hot pressing mechanism 2, upper cover loading preheating mechanism 3, hot pressing mechanism 4, and cold pressing mechanism 5. The double-speed chain conveyor 100 is used to transport the carrier positioning device 200 to the processing station of the above-mentioned mechanisms.

[0041] In a specific embodiment, by setting up a double-speed chain conveyor 100, the carrier positioning device 200 is conveyed on the double-speed chain conveyor 100. The folding hot pressing mechanism 2, the upper cover feeding preheating mechanism 3, the hot pressing mechanism 4, and the cold pressing mechanism 5 have processing stations that match the carrier positioning device 200. When the carrier positioning device 200 moves to each of the processing stations of the above-mentioned mechanisms, each mechanism processes the material at the processing station.

[0042] Workflow: First, the earphone blank is manually placed into the carrier positioning device 200 on the lifting mechanism 1 at the loading end. The pneumatic double-speed chain conveyor 100 is then activated to move the carrier positioning device 200 to the processing station of the folding and hot-pressing mechanism 2. The carrier positioning device 200 moves upward, pushing the earphone blank to the preset processing station. The folding and hot-pressing mechanism 2 folds and hot-presses the earphone blank. Then, the double-speed chain conveyor 100 moves the carrier positioning device 200 forward to the processing station of the top cover loading and preheating mechanism 3. The top cover loading and preheating mechanism 3 first loads the top cover onto the earphone blank, then preheats and presses the covered earphone blank to form the earphone case. Afterward, the double-speed chain conveyor 100... After hot pressing, the headphone box is transferred to the processing station of the hot pressing mechanism 4. The hot pressing mechanism 4 presses down and applies a preset temperature to the pressing area of ​​the headphone box. Then, the double-speed chain conveyor 100 transfers the headphone box to the processing station of the cold pressing mechanism 5. The cold pressing mechanism 5 presses down to cool the hot-pressed headphone box. After processing, the headphone box is unloaded by the lifting mechanism 1 at the discharge end. Then, the lifting mechanism 1 at the discharge end moves the empty carrier positioning device 200 down to the lower double-speed chain conveyor layer 102. The lower double-speed chain conveyor layer 102 transports the empty carrier positioning device 200 to the lifting mechanism 1 at the loading end. The lifting mechanism 1 moves the empty carrier positioning device 200 up to the loading station at the loading end, starting a new round of cyclic processing and realizing automatic processing of the headphone box.

[0043] Furthermore, such as Figure 2 As shown, the double-speed chain conveyor 100 consists of an upper double-speed chain conveyor layer 101 and a lower double-speed chain conveyor layer 102. The loading end and the unloading end of the double-speed chain conveyor 100 are respectively provided with the lifting mechanism 1. The lifting mechanism 1 is used to convey the carrier positioning device 200 to the upper double-speed chain conveyor layer 101 and the lower double-speed chain conveyor layer 102.

[0044] Specifically, by setting the double-speed chain conveyor 100 as a two-layer structure, and setting the lifting mechanism 1 at the loading end and the unloading end of the upper double-speed chain conveyor layer 101 and the lower double-speed chain conveyor layer 102 respectively, the lifting mechanism 1 is used to load and unload the carrier positioning device 200, forming a moving closed loop of the carrier positioning device 200.

[0045] Furthermore, such as Figure 3 As shown, the vehicle positioning device 200 includes a fixture position 201 for placing an earphone box. A bevel cutting mechanism 202 is provided at the bottom of the fixture position 201. The bevel cutting mechanism 202 is connected to a bevel cutting drive mechanism 203. The bevel cutting drive mechanism 203 is used to push the bevel cutting mechanism 202 to lift the fixture position 201 upward.

[0046] Specifically, by setting a beveling drive mechanism 203 at the bottom of the fixture position 201, the beveling drive mechanism 203 pushes the beveling mechanism 202 to lift the fixture position 201 upward, thereby lifting the fixture position 201 to the processing station of each mechanism.

[0047] Furthermore, such as Figure 3 As shown, the oblique cutting mechanism 202 includes a pushing block 2021 and a lifting block 2022. The pushing block 2021 has a slope surface with a preset angle. An oblique cutting drive cylinder 2030 is used, and an oblique cutting slider 2031 is connected to the piston rod of the oblique cutting drive cylinder 2030. The bottom of the oblique cutting slider 2031 is slidably connected to the oblique cutting slide rail 2032. The pushing block 2021 is fixedly connected to the oblique cutting slider 2031. One end of the lifting block 2022 is slidably connected to the slope surface of the pushing block 2021, and the other end of the lifting block 2022 is fixedly connected to the bottom of the fixture position 201. The oblique cutting drive mechanism 203 pushes the pushing block 2021 to move the lifting block 2022 up and down to lift the fixture position 201.

[0048] Specifically, the lifting block 2022 of the oblique cutting mechanism 202 moves along the slope of the pushing block 2021 under the drive of the oblique cutting drive cylinder 2030, thereby lifting the fixture position 201 by moving the lifting block 2022 up and down.

[0049] Furthermore, such as Figure 4 As shown, the folding and hot pressing mechanism 2 is disposed above the fixture position 201. The folding and hot pressing mechanism 2 includes a folding support foot 20, a support plate 21 is fixed on the folding support foot 20, a first through groove 210 communicating with the fixture position 201 is disposed in the middle of the support plate 21, a folding station 211 is disposed above the first through groove 210, the folding station 211 is used to match the fixture position 201, and a plurality of folding cylinders 212 are disposed at intervals around the folding station 211.

[0050] Specifically, the headphone blank box in the jig position 201 on the folding station 211 is folded by the folding cylinder 212.

[0051] Furthermore, such as Figure 4As shown, a pressing mechanism 22 is provided above the folding station 211. The pressing mechanism 22 includes a mounting top plate 220, a pressing plate 221, a folding plate 222, and an elastic pressure plate 223. A first cylinder drive assembly 224, a second cylinder drive assembly 225, and a third cylinder drive assembly 226 are mounted on the mounting top plate 220. The piston rod of the first cylinder drive assembly 224 passes through the mounting top plate 220 and the pressing plate 221 and is fixedly connected. The piston rod of the second cylinder drive assembly 225 passes through the pressing plate 221 and the top surface of the folding plate 222 and is fixedly connected. The piston rod of the third cylinder drive assembly 226 passes through the pressing plate 221, the folding plate 222, and the elastic pressure plate 223 and is fixedly connected.

[0052] Specifically, firstly, the elastic pressure plate 223 is pushed down by the third cylinder drive assembly 226 to position the earphone blank. Then, the folding plate 222 is pressed down by the second cylinder drive assembly 225 to press down the folding edge of the earphone blank. Finally, the pressing plate 221 is pushed down by the first cylinder drive assembly 224 to press the earphone blank together.

[0053] Furthermore, such as Figure 5 As shown, the cover feeding and preheating mechanism 3 includes a cover feeding device 30, a cover transfer device 31, and a preheating device 32; the preheating device 32 is disposed on one side of the cover feeding device 30; the cover transfer device 31 is disposed above the cover feeding device 30; specifically, by disposing of the cover feeding device 30 and the preheating device 32 above a processing station, the continuous feeding and preheating of the cover can be completed in one go.

The loading station 313 is provided with pusher slide rails 3130 on both sides. Pusher sliders 3131 are slidably connected to the pusher slide rails 3130. U-shaped push plates 3132 are fixedly connected to the pusher sliders 3131. The U-shaped push plates 3132 are fixedly connected to the piston rod of the pusher cylinder 3133.

[0056] The cover is transferred to the loading station 313 by the cover transfer device 31. After the previous cover is preheated and pressed, the pusher cylinder 3133 pulls the U-shaped pusher plate 3132 to push the cover to the processing station for preheating and pressing.

[0057] Furthermore, such as Figure 5 As shown, the preheating device 32 includes a pre-pressing support plate 320, on which a preheating pressing station 321 is provided.

[0058] Specifically, the preheating cylinder 322 pushes down the preheating plate 323 to preheat the upper cover on the preheating station 321.

[0062] Specifically, after hot pressing, the headphone box is cooled and fixed in shape by the cold pressing mechanism 5, thus completing the processing.

[0063] Furthermore, such as Figure 2 As shown, the lifting mechanism 1 includes a material feeding bracket 10 for placing the carrier positioning device 200. The bottom of the material feeding bracket 10 is provided with a lifting cylinder assembly 11. The lifting cylinder assembly 11 includes a lifting cylinder 110 and lifting guide columns 111 disposed on both sides of the lifting cylinder 110.

[0064] Specifically, after the processed headphone box is manually unloaded at the discharge end, the empty carrier positioning device 200 is moved down to the lower layer double-speed chain conveyor layer 102 by the lifting mechanism 1 at the discharge end. The lower layer double-speed chain conveyor layer 102 transports the empty carrier positioning device 200 to the loading end, and the carrier positioning device 200 is moved up to the loading station by the lifting mechanism 1 at the loading end, and enters the next round of cyclic processing.
