Description

Technical Field

[0001] This invention relates to the technical field of product material supply, and particularly to a mobile phone earpiece mesh sheet film material supply module. Background Technology

[0002] In the modern mobile phone manufacturing industry, the earpiece mesh is a key component that ensures the acoustic performance and dust and water resistance of the earpiece, making the material supply process crucial. As mobile phones become thinner, lighter, and more high-performance, the earpiece mesh is becoming increasingly precise and is often supplied in the form of sheet-like film, which places extremely high demands on the material supply mechanism. Currently, there are various types of feeding mechanisms for sheet materials. Some traditional feeding mechanisms use roll-to-strip materials, but for precision sheet-like films such as mobile phone earpiece mesh, roll-to-strip materials are prone to bending and deformation, causing irreparable damage and affecting their acoustic performance and appearance. Therefore, most mobile phone earpiece meshes use sheet-to-strip materials that are attached to a base film to protect the product's integrity during transportation and processing. However, this sheet-to-strip material cannot be directly adapted to existing roll-to-strip feeding mechanisms. Some existing technologies use methods such as separating the sheet material through a suction device and then conveying it to a subsequent processing device to achieve continuous and stable feeding of sheet materials.

[0003] For example, Chinese patent CN217263275U, entitled "A Continuous Feeding Device for Sheet Materials," describes a feeding device that carries sheet materials and alternately transports them to a suction device. The suction device uses a suction cup mechanism and connected to it a first lifting mechanism and a first translation mechanism to pick up the sheet materials. However, this method of material handling has defects; it cannot guarantee reliable peeling of the sheet material from the sheet film, and problems such as mesh residue and damage are prone to occur, which is detrimental to the use of subsequent equipment and greatly affects production efficiency and product quality. Some feeding mechanisms use a feeding assembly to feed sheet material strips, such as a sheet material strip feeding mechanism (publication CN220906594U), which includes a mounting frame, a hopper assembly, a feeding assembly, and a feeding assembly. Workers stack sheet-like materials in the hopper assembly, and the material handling assembly retrieves them onto the feeding platform. A gap exists between the feeding platform and the material feeding platform to allow the bottom film to pass through. The material feeding roller rotates, moving the bottom film forward. The bottom film bends, thus feeding the sheet-like materials from the sheet-like material onto the feeding platform. However, this method is prone to inaccurate feeding positions for sheet-like materials like those used in mobile phone earpieces, which are small in size and require extremely high precision. This can lead to mesh misalignment and falling off, failing to meet the high-precision requirements of mobile phone manufacturing. If a simple, precisely positioned, floating spring-loaded ejector pin could be designed to efficiently feed the material while protecting the mesh, effectively preventing mesh residue, misalignment, and damage, the aforementioned problems could be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mobile phone earpiece mesh sheet film feeding module with a simple structure, capable of precise product positioning, and floating spring pins that can efficiently feed material while protecting the mesh, effectively avoiding mesh residue, mesh offset and damage.

Detailed Implementation

[0017] like Figures 1 to 8 As shown, in this embodiment, the present invention includes a transverse module 1, a feeding carrier module 2, and a separation module 3. The feeding carrier module 2 includes a carrier plate 21, several sets of floating ejector pin modules 22, and a fixed base plate 23. The several sets of floating ejector pin modules 22 are disposed between the carrier plate 21 and the fixed base plate 23. The carrier plate 21 is connected to the support end of the transverse module 1 through several sets of support columns 24. The separation module 3 is connected to the movable end of the transverse module 1 and cooperates with the film material product 4 on the carrier plate 21. Thus, the feeding carrier module 2 is fixed to the fixed end of the transverse module 1 by the support columns, and the separation module 3 is fixed to the movable end of the transverse module 1 by the module connecting plate, allowing for back-and-forth movement of the modules. like Figure 1 As shown, in this embodiment, the transverse module 1 includes a base plate 11 and a linear module 12. The linear module 12 is disposed on the upper surface of the base plate 11. The carrier plate 21 is connected to the upper surface of the base plate 11 through several sets of support columns 13. The separation module 3 is connected to the movable end of the linear module 12. Therefore, the linear module 12 realizes the forward and backward movement of the pressure plate module.

[0018] like Figures 4 to 6 As shown, in this embodiment, the separation module 3 includes a fixed plate 31, a separation module 32, and a pressure plate module 33. The fixed plate 31 is connected to the movable end of the linear module 12. The pressure plate module 33 includes two sets of pressure plate support plates 331, two sets of film pressing cylinders 332, and a film pressing cover plate 333. The two sets of pressure plate support plates 331 are respectively disposed at both ends of the fixed plate 31. The two sets of film pressing cylinders 332 are respectively disposed on the outside of the two sets of pressure plate support plates 331. The two ends of the film pressing cover plate 333 are respectively connected to the movable ends of the two sets of film pressing cylinders 332 and cooperate with the bottom film end of the film material product 4 on the carrier plate 21. The separation module 32 is disposed on the upper surface of the fixed plate 31 and cooperates with the film material end of the film material product 4 through several sets of floating ejector pin modules 22. Therefore, the pressure plate 333 in the pressure plate module 33 is fixed by the two sets of pressure cylinders 332 and related fasteners. The pressure cylinders 332 can move the pressure plate 333 up and down in the Z direction to achieve the effect of pressure.

[0019] like Figures 4 to 6 As shown, in this embodiment, the separation module 32 includes a separation support plate 321, several sets of separation lifting plates 322, several sets of separation top blocks 323, and several sets of separation cylinders 324. The separation support plate 321 is disposed in the middle of the upper end surface of the fixed plate 31. The several sets of separation lifting plates 322 are slidably engaged with the two sides of the support surface of the separation support plate 321 via slide rails. The several sets of separation cylinders 324 are disposed on both sides of the upper end surface of the fixed plate 31. The movable ends of the several sets of separation cylinders 324 are connected to the corresponding separation lifting plates 322. The several sets of separation top blocks 323 are disposed at the lifting ends of the corresponding separation lifting plates 322 and drive the corresponding floating pin module 22 to cooperate with the film product 4. Therefore, the separating top block 323 can move up and down in the Z direction through the separating cylinder 324 fixed at the bottom. The separating top block 323 lifts the floating pin module 22, so that the pins on the floating pin module 22 can lift and separate the film particles of the film product 4.

[0020] like Figure 3 , Figure 7 as well as Figure 8As shown, in this embodiment, the floating ejector module 22 includes a spring pressure plate 221, an ejector guide block 222, and several sets of ejector pins 223. The spring pressure plate 221 is connected to the lower end of the ejector guide block 222 by several fixing screws 224. The several sets of ejector pins 223 are disposed inside the ejector guide block 222 and float in cooperation with the spring pressure plate 221 through several ejector springs 225. The lower end of the carrier plate 21 is provided with an ejector mounting groove 25, and the ejector guide block 222 slides in cooperation with the ejector mounting groove 25. The fixed base plate 23 is disposed at the lower end of the carrier plate 21 and is limited in cooperation with the several sets of floating ejector modules 22. It can be seen that the ejector guide block 222 is used to position and guide the several sets of ejector pins 223. When the several sets of ejector pins 223 are lifted upward from the lower end face of the spring pressure plate 221, the ejector springs 225 provide the effects of pressing buffer and releasing reset.

[0021] like Figure 7 and Figure 8 As shown, in this embodiment, the upper end of the ejector pin guide block 222 is in floating engagement with the bottom of the ejector pin mounting groove 25 via several floating springs 226. Thus, the floating springs 226 serve as a buffer for the sliding of the ejector pin guide block 222 within the ejector pin mounting groove 25, as well as providing a resetting effect.

[0022] like Figure 3 As shown, in this embodiment, the carrier plate 21 is provided with a plurality of sets of lifting holes 26, which correspond to a plurality of sets of floating ejector pin modules 22. A plurality of ejector pins 223 engage with the film material end of the film material product 4 through the lifting holes 26. Thus, the ejector pins 223 are lifted, and engage with corresponding film material particles on the film material product 4 through the lifting holes 26.

[0023] like Figure 6 As shown, in this embodiment, the film pressing cover plate 333 is provided with a plurality of material picking ports 334, which correspond to a plurality of lifting holes 26. The external material picking mechanism picks up the film material through the material picking ports 334. Thus, when the film material product 4 is lifted, the film material particles are located within the material picking ports 334, which facilitates positioning and picking up by an external robot or material picking equipment.

[0024] like Figure 1 and Figure 2As shown, in this embodiment, a light source module 5 is provided on the upper end of the fixing plate 31. The light source module 5 includes a light source support plate 51 and a light source 52. The light source 52 is connected to the movable ends of the two sets of pressing cylinders 332 through the light source support plate 51. Therefore, the light source module 5 moves up and down with the pressing cylinders 332, maintaining the optimal light source height after the pressing cover plate 333 presses the film product 4.

[0025] like Figure 3 As shown, in this embodiment, the upper surface of the carrier plate 21 is provided with a plurality of positioning pins 6 and a film detection sensor 7. Thus, the plurality of positioning pins 6 can position the sheet film material placed on the carrier plate 21, while the carrier plate 21 is provided with a plurality of suction holes. These suction holes, connected to a vacuum circuit, can firmly hold the positioned sheet film material to prevent it from shifting during the material handling process.

[0026] The working principle of this invention is as follows: The external feeding module places the sheet film with the mobile phone earpiece mesh onto the call number carrier plate 21. After the sheet film is positioned by several positioning pins 6, the carrier plate 21 vacuum-tightens the sheet film. The separation module 3 moves to the bottom of the carrier plate 21 through the linear module 12, and the film pressing cover 333 descends to press the sheet film. The corresponding separation cylinder 324 extends its movable end, driving the separation top block 324 to push out the floating ejector module 22. Several ejector pins 223 push out the mobile phone earpiece mesh sheet adhered to the sheet film. The six-axis robot arm picks up the sheet film with visual positioning guidance. After the lifting and picking is completed, all components are reset, and the mobile phone earpiece mesh sheet film to be picked up is replaced. By repeating the above steps, the precise positioning, lifting, peeling and feeding of the mobile phone earpiece mesh sheet film can be achieved.

[0027] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
