Description

Technical Field

[0001] This utility model relates to automated equipment, and more particularly to a wireless earphone case inner shell assembly equipment. Background Technology

[0002] With the development of the times, industrial production technology is also developing rapidly, and automated equipment is being used more and more in industrial production. Currently, wireless earphones usually come with an earphone case for storing the earphones. The earphone case usually needs to assemble an inner shell inside that matches the shape of the earphones to fix the earphones. In order to make the size more compact, the earphones usually need to be placed at an angle inside the earphone case. In order to match the angle of the earphones, the inner shell also needs to be assembled at an angle inside the earphone case. The assembly end inside the earphone case also needs to be set at an angle to adapt to the angled inner shell. Since the assembly end is set at an angle, traditional assembly mechanisms usually have difficulty assembling the angled assembly end. Therefore, the inner shell can only be assembled manually. In the industrial field that emphasizes cost reduction and efficiency improvement, it lacks competitiveness and is not conducive to large-scale promotion and industrialized production.

When the headphone box needs to be swung, the first lifting cylinder 52 lifts the carrier from the main line 1 and extends the carrier into the receiving opening of the swing frame 55. Then, the clamping cylinder 58 drives the clamping blocks 59 to move closer together to fix the carrier. After the carrier is fixed, the first swing cylinder 56 drives the swing plate 54, the swing frame 55, the second swing cylinder 57, the carrier, and the headphone box to rotate around the Y-axis, thereby counteracting the tilt angle of the headphone box assembly end in the Y-axis direction.

The pressure holding block 65 can squeeze the inner shell of the earphone box that is lifted by the second top plate 63 under the drive of the pressure holding cylinder 64. When it is necessary to secure the inner shell, the second lifting cylinder 62 lifts the carrier from the main line 1, and then the pressure holding cylinder 64 drives the pressure holding block 65 to press the inner shell on the headphone case, thus securing the inner shell and the headphone case. In some optional embodiments, the headphone case and the inner shell are secured by snap-fit ​​fasteners.

[0039] Optionally in this embodiment, there are two assembly stations, which are spaced apart along the main flow line 1. The inner shell is divided into a left inner shell and a right inner shell. One assembly station is used to assemble the right inner shell, and the other assembly station is used to assemble the left inner shell.

[0040] Movement Process: First, the carrier transport module 2 places the carrier with the headphone box fixed on the main line 1. Then, driven by the main line 1, the carrier moves to the first lifting cylinder 52. The first lifting cylinder 52 lifts the carrier off the main line 1. Then, the flipping module 5 rotates the carrier along the X and Y axes respectively to counteract the tilt angle of the headphone box assembly end. Then, the robotic arm 41 drives the finger cylinder 42 to move to the material tray. After the finger cylinder 42 clamps the inner shell, it moves to the upper-view camera 8 driven by the robotic arm 41. The upper-view camera 8 detects whether the appearance of the bottom end of the inner shell is qualified. If it is qualified, the robotic arm 41 places the inner shell on the headphone box assembly end. If the inner shell is unqualified, the robotic arm 41 places the inner shell in the scrap position of the material tray. After the inner shell is placed on the headphone box assembly end, the first lifting cylinder 52 lowers the carrier. Returning to the main line 1, the carrier moves to the second lifting cylinder 62 under the drive of the main line 1. The second lifting cylinder 62 lifts the carrier, and then the pressure holding cylinder 64 drives the pressure holding block 65 to squeeze the inner shell, fixing the inner shell and the earphone box. Then the second lifting cylinder 62 puts the carrier back to the main line 1, completing the assembly of one side of the inner shell. Then the second downward-looking camera 92 detects whether the assembly position of the inner shell is qualified. If it is not qualified, the main line 1 directly drives the carrier to move to the non-conforming product unloading mechanism 10. The non-conforming product unloading mechanism 10 places the carrier on the non-conforming product flow line 20. If the inner shell assembly is qualified, the same process is used to assemble the inner shell of the other side. After the assembly of the inner shells on both sides is completed, the main line 1 drives the carrier to move to the discharge end of the main line 1, thereby realizing the automated assembly of the inner shell of the wireless earphone box.

[0041] The wireless earphone case inner shell assembly equipment in this embodiment has the advantage of a high degree of automation.
