Description

Technical Field

[0001] This invention relates to the field of ear cover manufacturing technology, and in particular to an ear cover production line. Background Technology

[0002] Over-ear headphones, as the name suggests, are worn on the head and not inserted into the ear canal. Unlike in-ear headphones, over-ear headphones consist of a headband, earcups, drivers, cables, and ear tips. The ear tips of over-ear headphones are used to cover the foam padding and can reduce pressure on the head when wearing the headphones, improving wearing comfort.

[0003] The current production process for ear tips in over-ear headphones generally includes steps such as top sheet forming, baking, cooling, laser punching, bottom sheet welding, double-sided tape application, and mesh fabric application. Each step requires a large number of workers to load and unload materials. For example, after the top sheet is formed, workers need to collect the formed sheets and then push them to the baking equipment using a trolley. The sheets are then placed one by one into the baking station, and so on. After each step, workers are needed to transport the materials. Therefore, the existing ear tip production process suffers from low automation and low production efficiency.

Detailed Implementation

[0054] This invention discloses an ear cover production line to solve the technical problem of low production efficiency caused by low automation in the existing ear cover production process.

Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Laser punching mechanism for punching holes in cooled dough; 5. High-frequency welding mechanism for welding base and dough; 6. Double-sided adhesive bonding mechanism for bonding double-sided adhesive to dough; 7. Mesh bonding mechanism for bonding mesh to dough; 8. Fixture for fixing dough and fixture return conveyor belt for transporting fixture.

[0058] The fixture includes an outer ring, an inner core, and an aluminum sleeve. Specifically, the aluminum sleeve is fitted on the outside of the inner core, and the outer ring is fitted on the outside of the aluminum sleeve. The aluminum sleeve, outer ring, and inner core are assembled to form the fixture.

[0059] The dough forming mechanism 1, the baking mechanism 2, the cooling mechanism 3, the laser punching mechanism 4, the high-frequency welding mechanism 5, the double-sided adhesive bonding mechanism 6, and the mesh bonding mechanism 7 are arranged sequentially on the side of the fixture return conveyor belt 8.

[0060] In this embodiment, the earmuff's outer layer is automatically transferred to the baking mechanism 2 after passing through the outer layer forming mechanism 1 for baking. After baking, the outer layer enters the cooling mechanism 3 for cooling and shaping. Subsequently, the cooled outer layer is transferred to the laser drilling device for drilling. Then, the drilled outer layer is automatically transferred to the high-frequency welding mechanism 5, which welds the outer layer to the base layer. After welding, the outer layer enters the double-sided adhesive bonding mechanism 6, which automatically applies double-sided adhesive to the surface of the outer layer. Finally, the outer layer with double-sided adhesive applied enters the mesh fabric bonding mechanism 7, which applies the mesh fabric to the outer layer. Thus, the earmuff production process is completed. The entire process is completed by automated equipment, requiring no manual operation, which greatly improves the production efficiency of earmuffs.

[0064] The first electric turntable 101 is mounted on the first workbench. The first electric turntable 101 has a first shaft hole at its center. The first electric turntable 101 has a plurality of forming stations 108 arranged radially around the first shaft hole. A fixture aluminum sleeve placement position 109 is provided between each two adjacent forming stations 108. Each forming station 108 has a pre-pressing plate placement position 110 on the side facing the shaft hole.

[0065] The fixture feeding assembly, the dough feeding assembly 102, the prepress plate feeding assembly 103, the fixture aluminum sleeve feeding assembly 104, the prepress plate unloading assembly 105, the pressure holding assembly 106, and the first transfer gripping assembly 107 are sequentially installed on the worktable in the clockwise rotation direction of the electric turntable. The first transfer gripping assembly 107 is used to grip the formed dough and the fixture together and transfer them to the baking mechanism 2.

[0066] Specifically, the aforementioned fixture loading assembly is a multi-axis robot;

[0067] The dough feeding assembly 102 includes a material cylinder for loading dough, a multi-axis movable mechanical gripper, a conveyor belt, and a multi-axis robot. The mechanical gripper grabs the dough from the material cylinder onto the conveyor belt, the conveyor belt transports the dough to one side of the multi-axis robot, and the multi-axis robot grabs the dough onto the forming station 108.

[0072] It should be noted that the fixture feeding assembly can sequentially place the fixture outer ring and fixture inner core onto the forming station 108, so that the fixture outer ring is located outside the fixture inner core. The fixture feeding assembly also places the fixture aluminum sleeve onto the fixture aluminum sleeve placement position 109 of the first electric turntable 101. Then, the first electric turntable 101 rotates clockwise, causing the forming station 108 to rotate to the position of the fabric feeding assembly. The fabric feeding assembly places the fabric onto the forming station 108, covering the fixture outer ring and fixture inner core. Next, the first electric turntable 101 continues to rotate clockwise, causing the forming station 108 to rotate to the position of the pre-press plate feeding assembly 103. The pre-press plate feeding assembly 103 places the pre-press plate from the pre-press plate placement position 110 onto the forming station 108, pre-pressing the fabric and fixing its position. Then, the first electric turntable 101 continues... The clockwise rotation causes the forming station 108 to rotate to the fixture aluminum sleeve feeding assembly 104. At this time, the fixture aluminum sleeve feeding assembly 104 assembles the fixture aluminum sleeve between the fixture inner core and the fixture outer ring, and clamps the fixture aluminum sleeve onto the dough. Then, the first electric turntable 101 continues to rotate clockwise, causing the forming station 108 to rotate onto the pre-press plate unloading assembly 105. The pre-press plate unloading assembly 105 moves the pre-press plate on the forming station 108 to the pre-press plate placement position 110. Subsequently, the electric turntable rotates the forming station 108 onto the pressure holding assembly 106. The pressure holding assembly 106 holds the dough under pressure to form the dough. Finally, the first electric turntable 101 rotates the forming station 108 to the position of the first intermediate transfer gripping assembly 107.

[0112] After high-frequency welding, the outer sheet is picked up by the fourth transfer gripping assembly 603 and placed on the double-sided adhesive bonding station 602. The fourth electric turntable 601 rotates, moving the outer sheet below the fixture aluminum sleeve gripping assembly 604. At this time, the first clamping assembly 606 clamps the outer sheet, and then the fixture aluminum sleeve gripping assembly 604 picks up the fixture aluminum sleeve from the fixture and places it on the fixture return conveyor belt 8. Next, the fixture outer ring gripping assembly 605 picks up the fixture outer ring from the fixture and places it on the fixture return conveyor belt 8. In this process, the fixture... The outer ring and the aluminum sleeve of the fixture are returned to the dough forming mechanism 1 by the fixture return conveyor belt 8, waiting to be grabbed by the fixture feeding component. Then, the dough continues to move to the second clamping component 609 by the fourth electric turntable 601. The second clamping component 609 clamps the dough. The bonding component 607 picks up the double-sided adhesive from the double-sided adhesive feeder 608 and applies the double-sided adhesive to the top surface of the dough. Finally, the dough enters the heating device by the fourth electric turntable 601. The heating device heats the dough to enhance the bonding effect of the double-sided adhesive.
