[0028] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] This specific embodiment details the magnetic mounting device for the headphone cover described in this application, such as... Figures 1-9As shown, the headphone cover magnet mounting equipment includes: a main line 1, an assembly mechanism 4, a magnet feeding mechanism 5, a first lifting mechanism 2, a second lifting mechanism 3, a detection mechanism 6, a pressure holding mechanism 7, a discharge mechanism 8, and a defective product flow line 9. The main line 1 has an inlet and an outlet at its two ends. The assembly mechanism 4 and the magnet feeding mechanism 5 are adjacent to each other on the side of the main line 1. The detection mechanism 6 is located on the side of the main line 1, away from the assembly mechanism 4. The defective product flow line 9 is located on the side of the main line 1, near the outlet end. The discharge mechanism 8 is located next to the defective product flow line 9. The pressure holding mechanism 7 is located above the main line 1, between the detection mechanism 6 and the discharge mechanism 8. The first lifting mechanism 2 is located inside the main line 1, near the assembly mechanism 4. The second lifting mechanism 3 is located inside the main line 1, below the pressure holding mechanism 7. A carrier is also included. The system can hold workpieces, and the carrier holding the workpieces can be placed on the main line 1 and moved from the inlet end to the outlet end of the main line 1 under the drive of the main line 1. The first lifting mechanism 2 and the second lifting mechanism 3 can both lift or lower the carrier and the workpieces. The magnet feeding mechanism 5 is equipped with magnets, which can be moved to the outlet end of the magnet feeding mechanism 5 under the drive of the magnet feeding mechanism 5. The assembly mechanism 4 can pick up the magnets located at the feeding end of the magnet feeding mechanism 5 and attach the magnets to the workpieces lifted by the first lifting mechanism 2.

The pressure holding mechanism 7 can squeeze the magnets on the workpieces lifted by the second lifting mechanism 3. The discharge mechanism 8 can move unqualified workpieces to the unqualified product flow line 9, and the unqualified workpieces can be moved away from the main line 1 under the drive of the unqualified product flow line 9. In use, the workpiece is first placed on the carrier. Then, driven by the main line 1, the carrier moves from the inlet end of the main line 1 to the outlet end of the main line 1. Before mounting, the carrier is lifted by the first lifting mechanism 2. Then, the assembly mechanism 4 picks up the magnet from the outlet end of the magnet feeding mechanism 5 and attaches the magnet to the workpiece. Then, the detection mechanism 6 checks whether the workpiece with the magnet attached is qualified. If it is qualified, the carrier is lifted by the second lifting mechanism 3. Then, the pressure holding mechanism 7 presses the magnet and the workpiece together to ensure that the magnet and the workpiece are firmly attached. Then, the carrier and the workpiece move to the outlet end of the main line 1 under the drive of the main line 1. If the workpiece is unqualified, the unqualified material discharge mechanism 8 drives the workpiece to the unqualified product flow line 9. The unqualified product flow line 9 drives the workpiece away from the main line 1. The empty carrier moves to the outlet end of the main line 1 under the drive of the main line 1. Since the entire mounting process is fully automated, the degree of automation is high, and the mounting accuracy is also higher than that of manual mounting. It has the advantages of high automation and high placement accuracy.

The first drive wheel 11 and the second drive wheel 12 are connected by the drive belt 13. The two first drive wheels 11 are connected by a drive shaft. The rotating shaft of the first motor is coaxially connected to the drive shaft. The bottom surface of the carrier can be placed on the two drive belts 13.

[0031] Optionally in this embodiment, the first lifting mechanism 2 includes a lifting cylinder and a top block. The lifting cylinder is fixed inside the main flow line 1, and the top block is fixed to the cylinder rod of the lifting cylinder. A positioning block protrudes from the top surface of the top block, and a positioning notch is provided on the bottom surface of the carrier for the positioning block to extend into. The top block can extend from between the two transmission belts 13 under the drive of the lifting cylinder to lift or lower the carrier. The first lifting mechanism 2 and the second lifting mechanism 3 have the same structure. The positioning block on the top surface of the top block is used to position the carrier to prevent the carrier from shaking during the lifting process.

[0032] Optionally in this embodiment, the assembly mechanism 4 includes a four-axis robotic arm 41, a nozzle holder 42, and a nozzle 43. The nozzle holder 42 is fixed to the end of the four-axis robotic arm 41, and the nozzle 43 is fixed to the nozzle holder 42. The nozzle 43 is connected to a vacuum generator. The nozzle 43 is capable of picking up or placing magnets.

[0033] Optionally in this embodiment, the magnet feeding mechanism 5 includes a fixed plate 51, a rotary motor, a rotating drum 52, a hopper 53, a first cylinder, a feeding platform 54, a second cylinder, a gravity block, and a stop block 55. The rotary motor is fixed to the fixed plate 51, and the rotating shaft of the rotary motor is coaxially connected to the rotating drum 52. At least one hopper 53 is vertically fixed to the outer peripheral wall of the rotating drum 52. A slot for accommodating magnets is vertically opened through the hopper 53. The magnets attract each other and are vertically stacked in the slot. The gravity block is slidably disposed in the hopper 53 and presses the top magnet from top to bottom by gravity. The first cylinder is fixed inside the rotating drum 52, and the stop block 55 is fixed to the cylinder rod of the first cylinder. The stop block 55 can block the magnets and supply them. The feeding platform 54 is slidably connected to the fixed plate 51 via a slide rail. The cylinder rod of the second cylinder is connected to the feeding platform 54.

The feeding platform 54 can move to a position directly below the hopper 53 under the drive of the second cylinder. The stop block 55 can move away from the hopper 53 under the drive of the first cylinder. The magnet at the bottom of the hopper 53 can fall into the cavity 56. The feeding platform 54 can move away from the hopper 53 under the drive of the second cylinder and separate the magnet in the cavity 56 from other magnets. When feeding is required, the hopper 53, fixed to the outer peripheral wall of the rotating drum 52, rotates under the drive of the rotary motor to a position close to the feeding platform 54. The feeding platform 54, driven by the second cylinder, approaches the adjacent hopper 53. Simultaneously, the stop block 55, driven by the first cylinder, moves away from the hopper 53 until the feeding platform 54 is directly below the hopper 53. At this point, the sinkhole 56 is directly opposite the bottom of the slot. The magnets placed inside the hopper 53 fall under the pressure of the gravity block, with the lowest magnet falling into the sinkhole 56. Only one magnet can be accommodated in the cavity 56, so the remaining magnets above the magnets in the cavity 56 will not enter the cavity 56. Then, the second cylinder drives the feeding platform 54 away from the hopper 53. At this time, the magnets in the cavity 56 are driven away from the hopper 53 and separated from the remaining magnets by the feeding platform 54. Then the magnets in the cavity 56 can be picked up by the assembly mechanism 4. At the same time as the feeding platform 54 moves away from the hopper 53, the first cylinder drives the stop block 55 to reset to directly below the hopper 53. The stop block 55 blocks the remaining magnets to prevent them from falling out of the hopper 53.

The material trough 91 is obliquely fixed to the side of the main flow line 1 by the support, with the end of the material trough 91 closer to the main flow line 1 being higher than the end farther from the main flow line 1. The rollers 92 are rotatably connected to the material trough 91 side by side via the rotating shaft. Baffles are provided on both sides of the material trough 91 that protrude upwards. The baffles can prevent the workpiece from moving out of the side of the material trough 91.

[0039] Movement Process: First, the workpiece is placed on the carrier, and then the carrier is placed at the inlet end of the main feed line 1. Driven by the main feed line 1, the carrier and workpiece move to a position close to the assembly mechanism 4. At this time, the first lifting mechanism 2 lifts the carrier and workpiece from the main feed line 1. Then, the four-axis robotic arm 41 drives the suction nozzle 43 to move to the feeding platform 54. The suction nozzle 43 picks up the magnet located in the sink 56 and moves the magnet above the first camera 102. The first camera 102 visually inspects whether the shape of the magnet meets the requirements. If the shape of the magnet does not meet the requirements, the four-axis robotic arm 41 drives the magnet... The iron is moved to the scrap position, and the suction nozzle 43 places the magnet at the scrap position. If the magnet's shape is qualified, the magnet is moved by the four-axis robotic arm 41 to the carrier lifted by the first lifting mechanism 2. Then, the four-axis robotic arm 41 attaches the magnet to the workpiece. In this embodiment, the workpiece is an earphone cover. Adhesive is provided at the magnet attachment position on the workpiece. Then, the first lifting mechanism 2 puts the carrier back to the main line 1. Then, the carrier moves to the detection mechanism 6 under the drive of the main line 1. The second camera 65 can be positioned and followed by the main line via the first electric lead screw 62 and the second electric lead screw 63. On the carrier 1, the second camera 65 can capture images of the workpieces on the carrier from top to bottom to check whether the appearance of the workpieces with attached magnets meets the requirements. If the appearance of the workpiece does not meet the requirements, the pressure holding mechanism 7 does not work, and the unqualified workpieces are moved to the vicinity of the discharge mechanism 8 under the drive of the main flow line 1. The fourth cylinder 82 drives the push plate 83 to push the unqualified workpieces and move them onto the roller 92 of the unqualified product flow line 9. Since the material trough 91 is inclined, the unqualified workpieces on the roller 92 can move away from the main flow line 9 under the action of gravity. One end of line 1, while the empty carrier moves to the discharge end of the main line 1 under the drive of the main line 1. If the appearance of the workpiece with the magnet attached is qualified, the carrier moves to the pressure holding mechanism 7 under the drive of the main line 1. Then the second lifting mechanism 3 lifts the carrier, and the pressure block 73 approaches and squeezes the magnet attached to the workpiece under the drive of the third cylinder 72 to ensure that the magnet and the workpiece are tightly connected. Then the second lifting mechanism 3 puts the carrier back into the main line 1, and then the carrier moves to the discharge end of the main line 1 under the drive of the main line 1. This process is repeated to realize the automated mounting of the magnet on the headphone cover.

[0040] The headphone cover magnet mounting equipment in this embodiment has the advantages of high automation and high mounting accuracy.
