Description

Technical Field

[0001] This utility model specifically relates to the field of earplug spraying technology, and more specifically to an earplug spraying positioning fixture and spraying equipment. Background Technology

[0002] The main purpose of applying adhesive after the earplugs are manufactured is as follows:

[0003] Fixing components: The different parts of the earbud (such as memory foam and silicone core) are firmly bonded together with adhesive to ensure that they will not shift or fall off due to external force or activity during daily use.

[0004] Enhanced structural stability: Spray adhesive can strengthen the overall structure of the earbuds, especially when multiple materials are combined (such as plastic, metal, silicone, etc.). The adhesive can provide a reliable connection and prevent parts from loosening or breaking.

[0005] Sealing, waterproofing, and dustproofing: For earplugs that require waterproofing, adhesive can be sprayed to fill gaps or seal edges to prevent moisture, dust, and other contaminants from entering.

[0042] In this embodiment, the length of the metal positioning rod 14 is not greater than the width of the fixture outer frame 11; one end of the metal positioning rod 14 is engaged with the slot 12, and the other end is suspended.

[0043] By adopting the above technical solution, the metal positioning rod 14 is designed in a suspended manner, which makes it easy to assemble and disassemble the metal positioning rod 14 with the fixture frame 11 and provides sufficient installation space.

[0044] In this embodiment, the inner sides of both ends of the jig frame 11 also have two grooves. The grooves are designed to ensure proper fit with the clip 244, thus preventing relative sliding when the jig is flipped and ensuring the stability of the jig during glue spraying and rotation.

[0045] A glue spraying device with an earplug positioning fixture includes a fixture mounting structure 24 for fixing the fixture outer frame 11, and a glue spraying assembly 22 is provided above the fixture mounting structure 24; wherein the fixture mounting structure 24 is fixed to the frame body 21; the glue spraying assembly 22 is fixed to the inner side wall of the top cover 25, and the top cover 25 is fixed to the frame body 21.

[0046] In this embodiment, the top of the top cover 25 is also provided with a negative pressure pipe 23; the other end of the negative pressure pipe 23 is connected to an air purification device.
