[0002] An earphone is one of the electronic products with a high daily usage frequency. For a wired earphone, its ear wire is one of the very important components. Generally, after the ear wire is manufactured, various tests need to be carried out on the ear wire, and only the ear wire that passes the tests can be used to complete the subsequent production of the earphone. Before carrying out various tests on the ear wire, the ear wire needs to be wrapped with a film to prevent damage to the ear wire surface during the tests.

[0003] The existing ear wire wrapping method usually uses the method of manually taking the film, manually aligning, and manually wrapping the film around the ear wire. This method has the defects of low work efficiency, incomplete wrapping, uneven wrapping appearance, and high labor cost. Moreover, there is no film wrapping module on the market that can replace manual labor, improve work efficiency, and improve the wrapping qualification rate.

[0004] Therefore, there is an urgent need for a film wrapping module that can improve work efficiency and the wrapping qualification rate to overcome the above defects. Summary of the Invention

The left lifting and pushing block and the right lifting and pushing block are also respectively arranged on the left and right sides of the carrier table and are initially at the same height as the carrier table or lower than the carrier table. The left side pushing block is arranged above the left lifting and pushing block, and the right side pushing block is arranged above the right lifting and pushing block. The left lifting and pushing block and the right lifting and pushing block each move in the up-down direction, and the left side pushing block and the right side pushing block each move in the horizontal direction.

[0007] Preferably, the rising height of the left lifting and pushing block and the right lifting and pushing block is the thickness of the object to be wrapped.

[0008] Preferably, the left lifting and pushing block selectively abuts below the left lifting and pushing block, and the right lifting and pushing block selectively abuts below the right lifting and pushing block.

[0009] Preferably, the film wrapping module further includes a left side pushing connecting block, a right side pushing connecting block, a left side pushing mounting plate and a right side pushing mounting plate. The left side pushing mounting plate and the right side pushing mounting plate are respectively installed on opposite sides of the pallet. The left cylinder is installed on the left side pushing mounting plate. The left side pushing connecting block is slidably arranged on the left side pushing mounting plate. The output end of the left cylinder is connected to the left side pushing connecting block. The left side pushing connecting block is connected to the left pushing block. The left cylinder drives the left connecting block to move, thereby driving the left pushing block to move. The right cylinder is installed on the right side pushing mounting plate. The right side pushing connecting block is slidably arranged on the right side pushing mounting plate. The output end of the right cylinder is connected to the right side pushing connecting block. The right side pushing connecting block is connected to the right pushing block. The right cylinder drives the right connecting block to move, thereby driving the right pushing block to move.

[0010] Preferably, the left side pushing connecting block, the right side pushing connecting block, the left side pushing mounting plate and the right side pushing mounting plate are all of L-shaped plate structures. The left side pushing connecting block includes a first vertical plate and a first horizontal plate. The left side pushing mounting plate includes a second vertical plate and a second horizontal plate. The first horizontal plate is slidably arranged on the second horizontal plate.

When the film wrapping module of the present invention works specifically, the film is located on the bearing platform. Since the left lifting and pushing block is initially at the same level as or lower than the bearing platform, the left lifting and pushing block is initially located below the film. In the first step, the left lifting and pushing block moves upward, thereby folding the left side of the film upward. In the second step, the left side pushing block moves to the right, thereby tightly wrapping the left side of the film to the right; then the left lifting and pushing block and the left side pushing block reset. In the third step, the right lifting and pushing block is initially located below the film, and the right lifting and pushing block moves upward, thereby folding the right side of the film upward. In the fourth step, the right side pushing block moves to the left, thereby tightly wrapping the right side of the film to the left. Thus, the action of tightly wrapping the film around the ear wire is completed. Therefore, the film wrapping module of the present invention has the advantages of high automation degree, improved work efficiency, improved wrapping qualification rate and reduced labor cost.

[0025] In order to elaborate in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0026] Please refer to Figures 1 to 5, the encapsulation module 3 of the present invention includes a pallet 301, a carrier 302 for carrying a film, a left lifting block 303 and a right lifting block 305 for driving the film to wrap upward, a left pushing block 304 and a right pushing block 306 for driving the film to wrap laterally, a left lifting cylinder 307 for driving the left lifting block 303 to move, a left side cylinder 308 for driving the left pushing block 304 to move, a right lifting cylinder 309 for driving the right lifting block 305 to move, and a right side cylinder 310 for driving the right pushing block 306 to move. The left lifting cylinder 307 and the right lifting cylinder 309 are installed on the pallet 301 at intervals. The output end of the left lifting cylinder 307 is arranged upward and connected to the left lifting block 303. The output end of the right lifting cylinder 309 is arranged upward and connected to the right lifting block 305. The left lifting block 303 and the right lifting block 305 are also respectively arranged on the left and right sides of the carrier 302 and are initially set at the same height as the carrier 302, so that initially, the left lifting block 303 and the right lifting block 305 are both located below the film. It can be understood that initially, the film is simultaneously located on the carrier 302, the left lifting block 303, and the right lifting block 305. Of course, in other embodiments, the left lifting block 303 and the right lifting block 305 are initially lower than the carrier 302 and can also move upward to wrap the ear wire upward. The left side cylinder 308 and the right side cylinder 310 are spaced apart in the left-right direction and are arranged on opposite sides of the pallet 301. The output end of the left side cylinder 308 is arranged to the right and connected to the left pushing block 304. The output end of the right side cylinder 310 is arranged to the left and connected to the right pushing block 306. The left pushing block 304 is arranged above the left lifting block 303, and the right pushing block 306 is arranged above the right lifting block 305. The left lifting block 303 and the right lifting block 305 each move in the up-down direction, and the left pushing block 304 and the right pushing block 306 each move in the horizontal direction. It should be noted that the left pushing block 304 is spaced apart from the left lifting block 303 in the up-down direction, and the right pushing block 306 is spaced apart from the right lifting block 305 in the up-down direction. More specifically, as follows:

[0027] Please refer to Figures 5 to 8, the rising heights of the left lifting block 303 and the right lifting block 305 are the thickness of the ear line. Preferably, the left lifting block 303 selectively abuts below the left lifting block 303, and the right lifting block 305 selectively abuts below the right lifting block 305. Thus, the left pushing block 304 and the right pushing block 306 are used to limit the positions of the left lifting block 303 and the right lifting block 305. Preferably, the upper surfaces of the left lifting block 303 and the right lifting block 305 are smooth surfaces, thereby reducing the resistance to the movement of the left pushing block 304 and the right pushing block 306. Preferably, the rightmost side of the left pushing block 304 and the leftmost side of the left lifting block 303 are aligned in the vertical direction. When the left lifting block 303 moves upward to the proper position, it abuts below the left pushing block 304, which is beneficial to limiting the position of the left lifting block 303. In addition, the left lifting block 303 also provides a bearing space for the movement of the left pushing block 304; the leftmost side of the right pushing block 306 and the rightmost side of the right lifting block 305 are aligned in the vertical direction. Similarly, when the right lifting block 305 moves upward to the proper position, it abuts below the right pushing block 306, which is beneficial to limiting the position of the right lifting block 305. In addition, the right lifting block 305 also provides a bearing space for the movement of the right pushing block 306.

[0028] Please refer to Figures 1 to 4 , the film wrapping module 3 further includes a left pushing connection block 3, a right pushing connection block 312, a left pushing mounting plate 313 and a right pushing mounting plate 314. The left pushing mounting plate 313 and the right pushing mounting plate 314 are respectively installed on opposite sides of the pallet 301. The left air cylinder 308 is installed on the left pushing mounting plate 313. The left pushing connection block 311 is slidably arranged on the left pushing mounting plate 313. The output end of the left air cylinder 308 is connected to the left pushing connection block 311. The left pushing connection block 311 is connected to the left pushing block 304. The left air cylinder 308 drives the left pushing connection block 311 to move, thereby driving the left pushing block 304 to move. The left pushing mounting plate 313 provides an installation space for the left air cylinder 308. The left pushing connection block 311 is used as an intermediate member to link the left pushing block 304, thereby optimizing the space arrangement of the film wrapping module 3. Specifically, both the left pushing connection block 311 and the left pushing mounting plate 313 are L-shaped plate structures. The left pushing connection block 311 includes a first vertical plate 3111 and a first horizontal plate 3112. The left pushing mounting plate 313 includes a second vertical plate 3131 and a second horizontal plate 3132. The first horizontal plate 3112 is slidably arranged on the second horizontal plate 3132. The top of the first vertical plate 3111 is connected to the left pushing block 304. The left air cylinder 308 is installed on the second vertical plate 3131. More specifically, the top of the first vertical plate 3111 is pivotally connected to the left pushing block 304, and a relatively small-angle rotation can be made between the first vertical plate 3111 and the left pushing block 304.

[0029] Please continue to refer to Figures 1 to 4, the right cylinder 310 is installed on the right push mounting plate 314. The right push connecting block 312 is slidably disposed on the right push mounting plate 314. The output end of the right cylinder 310 is connected to the right push connecting block 312. The right push connecting block 312 is connected to the right push block 306. The right cylinder 310 drives the right push connecting block 312 to move, thereby driving the right push block 306 to move. Specifically, both the right push connecting block 312 and the right push mounting plate 314 are L-shaped plate structures. Similarly, the right push connecting block 312 includes a third vertical plate (not shown in the figure) and a third horizontal plate (not shown in the figure). The right push mounting plate 314 includes a fourth vertical plate 3141 and a fourth horizontal plate 3142. The third horizontal plate is slidably disposed on the fourth horizontal plate 3142. The top of the third vertical plate is connected to the right push block 306. The right cylinder 310 is installed on the fourth vertical plate 3141. Similarly, the top of the third vertical plate is pivotally connected to the right push block 306, and a relatively small-angle rotation can be made between the third vertical plate and the right push block 306.

[0030] Please refer to Figures 1 to 2 , at the bottom of the first horizontal plate 3112, there is a slider 317, and at the top of the second horizontal plate 3132, there is a slide rail 318 for the slider 317 to slide. With the slider 317 and the slide rail 318, a guiding effect is provided for the movement of the left push connecting block 311. It can be understood that at the bottom of the third horizontal plate, there is a slider 317, and at the top of the fourth horizontal plate 3142, there is a slide rail 318 for the slider 317 to slide. With the slider 317 and the slide rail 318, a guiding effect is provided for the movement of the right push connecting block 312.

[0031] Please continue to refer to Figures 5 to 8 , in this embodiment, the left push block 304 is made of silica gel, and the right push block 306 is made of silica gel. The lower right side of the left push block 304 has an arc transition surface 321, and the lower left side of the right push block 306 has an arc transition surface 321. Since the silica gel material is elastic and flexible, and the lower right side of the left push block 304 has an arc transition surface 321, when the left push block 304 moves to the right, the air bubbles are discharged while wrapping the film, avoiding insufficient tightness of the film wrapping. Similarly, with the material and the arc transition surface 321 of the right push block 306, when the right push block 306 moves to the left, the air bubbles are discharged while wrapping the film, avoiding insufficient tightness of the film wrapping.

[0032] Please refer to Figure 1 and Figure 2, the pallet 301 also moves in the vertical direction. The film wrapping module 3 further includes a bottom plate 315 and a lifting cylinder 316 for driving the movement of the pallet 301. The lifting cylinder 316 is installed on the bottom plate 315, and the output end of the lifting cylinder 316 is connected to the pallet 301. Preferably, in this embodiment, the film wrapping module 3 further includes a guiding structure for guiding the movement of the pallet 301. The guiding structure includes guiding blocks 319 and guide rails 320. The guide rails 320 are provided on opposite sides of the pallet 301 and are vertically arranged. The guiding blocks 319 are provided on opposite sides of the bottom plate 315. When the lifting cylinder 316 drives the pallet 301 to move up and down, the guide rails 320 move relative to the guiding blocks 319 in the vertical direction.

[0033] Please refer to Figure 1 and Figure 3 , preferably, a plurality of suction holes 3021 are further provided on the surface of the carrier table 302, which is beneficial to the stable placement of the film position and prevents the film from shifting during the wrapping process.

[0034] It can be understood that in this embodiment, the object to be wrapped is an ear wire. Of course, in other embodiments, the object to be wrapped can be a strip-shaped object with a regular shape, so it is not limited thereto.

[0035] Combined with the attached drawings, the working principle of the film wrapping module 3 of the present invention is described as follows: When the film wrapping module 3 of the present invention is transferred to the film taking station, the lifting cylinder 316 drives the pallet 301 to move upward. When the carrier table 302 contacts the film and sucks the film tightly by means of the suction holes 3021, the lifting cylinder 316 then drives the pallet 301 to move downward. When the film wrapping module 3 of the present invention is transferred to the station for wrapping the ear wire, the lifting cylinder 316 drives the pallet 301 to rise so that the film on the carrier table 302 abuts against the upper ear wire. Then, the left lifting cylinder 307 drives the left lifting push block 303 to move upward, so that the left side of the film is folded upward; then, the left side cylinder 308 drives the left side push block 304 to move to the right, so that the left side of the film is folded to the right; then, the left lifting cylinder 307 and the left side cylinder 308 drive the left lifting push block 303 and the left side push block 304 to reset respectively; then the right lifting cylinder 309 drives the right lifting push block 305 to move upward, so that the right side of the film is folded upward; then, the right side cylinder 310 drives the right side push block 306 to move to the left, so that the right side of the film is folded to the left; then, the right lifting cylinder 309 and the right side cylinder 310 drive the right lifting push block 305 and the right side push block 306 to reset respectively. Then, the lifting cylinder 316 drives the pallet 301 to move downward to avoid the ear wire.

[0036] Compared with the prior art, the film wrapping module 3 of the present invention relies on the orderly cooperation among the bearing platform 302, the left lifting push block 303, the right lifting push block 305, the left side push block 304, the right side push block 306, the left lifting cylinder 307, the right lifting cylinder 309, the left side cylinder 308 and the right side cylinder 310, so as to fold the film in a certain order to wrap the ear wire. When the film wrapping module 3 of the present invention works specifically, the film is located on the bearing platform 302. Since the left lifting push block 303 is initially on the same platform as the bearing platform 302 or lower than the bearing platform 302, the left lifting push block 303 is initially located below the film. In the first step, the left lifting push block 303 moves upward, so as to fold the left side of the film upward. In the second step, the left side push block 304 moves to the right, so as to tightly wrap the left side of the film to the right; then the left lifting push block 303 and the left side push block 304 return to their original positions. In the third step, the right lifting push block 305 is initially located below the film, and the right lifting push block 305 moves upward, so as to fold the right side of the film upward. In the fourth step, the right side push block 306 moves to the left, so as to tightly wrap the right side of the film to the left. Thus, the action of tightly wrapping the film around the ear wire is completed. Therefore, the film wrapping module 3 of the present invention has the advantages of high automation degree, improved work efficiency, improved wrapping qualification rate and reduced labor cost.

[0037] The above-disclosed are only the preferred examples of the present invention, and the scope of the rights of the present invention cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
