[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.
[0030] like Figure 1 and Figure 2 As shown, an earphone shell coating machine 10 includes a machine base 100, a pressing assembly 200, and two film feeding assemblies 300. A feeding belt 400 is rotatably mounted on the machine base 100. The pressing assembly 200 includes a pressing drive 210, a pressing plate 220, and a soft block 230. The pressing drive 210 is mounted on the machine base 100, and the pressing plate 220 is mounted on the output shaft of the pressing drive 210, and the pressing plate 220 is located on the upper part of the feeding belt 400. A soft block 230 is disposed on the side of the pressure plate 220 near the feeding belt 400. Two film feeding assemblies 300 are disposed adjacently on the machine base 100. The film feeding assembly 300 includes a film roll 310, a film carrier plate 320, a film pressing drive 330, a film pressing plate 340, a film cutting drive 350, a film cutting knife 360, a film clamping drive 370, and at least two film clamping members 380. The film roll 310 is rotatably disposed on the machine base 100. 0 is used to release the film. The film carrier plate 320 is set on the side of the machine base 100 near the film roll 310. The film clamping drive 370 is set on the machine base 100. Each film clamping member 380 is spaced apart on the output shaft of the film clamping drive 370. The film clamping drive 370 is used to drive the film clamping members 380 to move closer to or away from the film carrier plate 320, so that the film clamping members 380 clamp the film away from the film carrier plate 320 and lay it horizontally on the feed belt 400. The film pressing drive 33 The film pressing plate 340 is set on the output shaft of the film pressing drive 330 and is located above the film carrier plate 320. The film pressing drive 330 is used to drive the film pressing plate 340 down to press the film on the film carrier plate 320. The film cutting drive 350 is set on the machine base 100 and the film cutting knife 360 is set on the output shaft of the film cutting drive 350. The film cutting drive 350 is used to drive the film cutting knife 360 to cut the film.
[0031] It should be noted that the headphone shell wrapping machine 10 of this application is used in conjunction with the material handling robot of an injection molding machine. Two film-laying assemblies 300 and a pressing assembly 200 are sequentially arranged on the machine base 100. Both film-laying assemblies 300 are used to release film. One film-laying assembly 300 is used to lay a first layer of film on the feeding belt 400, and the other film-laying assembly 300 is used to lay a second layer of film on the first layer of film. After the robot of the injection molding machine has filled the first layer of film with several headphone shells in rows and columns, the feeding belt 400 moves the first layer of film and several headphone shells to the other film-laying assembly 300. Then, the second layer of film is laid on each headphone shell. Then, the feeding belt 400 moves the two layers of film and each headphone shell to the pressing assembly 200. The pressing assembly 200 presses the two layers of film together to complete the packaging of the headphone shells. Finally, the feeding belt 400 continues to move the film-wrapped headphone shells to achieve unloading. Specifically, the pressing drive 210 is mounted on the machine base 100, and the pressing plate 220 is mounted on the output shaft of the pressing drive 210. The pressing drive 210 drives the pressing plate 220 to move up and down. For example, the pressing drive 210 is a cylinder. The soft block 230 is mounted at the bottom of the pressing plate 220. When the pressing plate 220 drives the soft block 230 to descend, the soft block 230 presses the two layers of film together to complete the packaging. The film roll 310 is a roll-shaped film structure that releases the film by rotation. The film roll 310 is rotatably mounted on one side of the machine base 100. The film carrier plate 320 is mounted on the machine base 100, and the film carrier plate 320 is arranged adjacent to the film roll 310. The film clamping drive 370 drives each film clamping member 380 to move laterally relative to the machine base 100, so that the film clamping member 380 can cross the feed belt 400 to move closer to or away from the film carrier plate 320. In one embodiment, the clamping component 380 is an air clamp. This allows the clamping component 380 to pull the film from the carrier plate 320 to the side of the machine 100 away from the carrier plate 320, so that the film is laid laterally on the feed belt 400. After the first layer of film is laid, the robot arm of the injection molding machine places a fixed quantity of earphone shells in rows on the first layer of film. Then, the pressing drive component 330 drives the pressing plate 340 to descend, so that the pressing plate 340 presses the film on the carrier plate 320. Then, the cutting drive component 350 drives the cutting blade 360 to move laterally to cut the film laid on the feed belt 400 and the film pressed by the pressing plate 340. Thus, by the cooperation of two film-laying components 300, a layer of film is laid at the bottom and top of the earphone shell respectively, and finally, the two layers of film are pressed together by the soft block 230 to complete the automatic packaging of the earphone shell. Compared to existing manual operations, it can effectively improve packaging efficiency and reduce labor costs by replacing manual operations.
[0032] In one embodiment, both the film cutting drive 350 and the film clamping drive 370 are screw modules driven by a motor. Further, in one embodiment, the film pressing drive 330 is a cylinder.
[0033] In one embodiment, the soft block 230 is made of sponge. In this way, the sponge presses the two thin films together, preventing the earphone shell located between the two thin films from being crushed.
[0034] like Figure 1 In one embodiment, a support frame 110 is provided on the machine base 100, the support frame 110 spans the feeding belt 400, and the pressing drive component 210 is provided on the support frame 110.
[0035] It should be noted that the support frame 110 spans both sides of the feeding belt 400, and the pressing drive 210 is installed on the support frame 110, so that the pressing drive 210 drives the pressing plate 220 to move up and down on the feeding belt 400.
[0036] like Figure 1 In one embodiment, the pressure plate 220 is provided with a plurality of spaced guide posts 240, and each guide post 240 is provided with a support frame 110.
[0037] Thus, each guide post 240 passes through the support frame 110. For example, a linear bearing is installed on the support frame 110, and the guide post 240 passes through the linear bearing to make the pressure plate 220 move stably up and down relative to the support frame 110.
[0038] like Figure 1 and Figure 3 As shown, in one embodiment, a plurality of clearance grooves 321 are provided on the carrier film plate 320, and the film clamping member 380 is used to extend into the clearance grooves 321 to clamp the film.
[0039] It should be noted that the film cutting knife 360 cuts the film along the edge of the film carrier plate 320. Thus, by opening the clearance groove 321 on the film carrier plate 320, the film clamping member 380 can clamp the film from the clearance groove 321, thereby enabling the film clamping drive member 370 to drive the film clamping member 380 to pull and traction the film to lay it on the feeding belt 400.
[0040] like Figure 1 As shown, in one embodiment, a roller 390 is also rotatably mounted on the machine base 100. The roller 390 is located between the film roll 310 and the carrier film plate 320 so that the roller 390 rolls with the film.
[0041] It should be noted that the film roll 310 is located below the machine base 100. In order for the film to be stably attached to the film carrier plate 320 so that it can be clamped by the film clamping member 380 or cut by the film cutting knife 360, a roller 390 is rotatably mounted on the machine base 100 at a position outside the film carrier plate 320. For example, the roller 390 is mounted on the machine base 100 by bearings, so that the roller 390 can rotate relative to the machine base 100.
[0042] like Figure 1 As shown, in one embodiment, the film feeding assembly 300 further includes a rotating shaft 3110 and two card holders 3120. The two card holders 3120 are arranged facing each other on the machine base 100. The rotating shaft 3110 passes through the film roll 310, and the two ends of the rotating shaft 3110 are rotatably connected to the two card holders 3120 respectively.
[0043] It should be noted that the film roll 310 has a roll-shaped structure, and its axis is usually provided with a drum. After the rotating shaft 3110 passes through the drum, the rotating shaft 3110 is rotatably connected to the two card holders 3120, so that the film roll 310 can rotate relative to the machine base 100.
[0044] like Figure 1 and Figure 4 As shown, in one embodiment, the card holder 3120 is provided with a card slot 3121, and a plurality of steel balls 3130 are rotatably disposed on the inner side wall of the card slot 3121 so that the outer side wall of the rotating shaft 3110 rolls with the steel balls 3130.
[0045] It should be noted that, for example, the slot 3121 has a U-shaped groove structure. The steel ball 3130 is embedded in the inner wall of the slot 3121, and part of the structure of the steel ball 3130 protrudes from the inner wall of the slot 3121. In this way, the rotating shaft 3110 is placed in the slot 3121, so that the multiple steel balls 3130 support the rotating shaft 3110, thereby enabling the rotating shaft 3110 to rotate stably within the slot 3121.
[0046] like Figure 4 As shown, in one embodiment, a stop 3140 is detachably provided on the inner sidewall of the slot 3121, and the stop 3140 is used to support the rotating shaft 3110.
[0047] It should be noted that, for example, a sliding groove is provided on the inner side wall of the slot 3121, and the two sides of the stop block 3140 slide into the sliding groove, so that the stop block 3140 can slide stably along the slot 3121 to support the rotating shaft 3110. In this way, the rotating shaft 3110 can be prevented from falling out of the slot 3121 due to accident. It should also be noted that when the stop block 3140 is inserted into the sliding groove, the stop block 3140 and the rotating shaft 3110 are in a non-contact state to avoid friction between the stop block 3140 and the rotating shaft 3110.
[0048] In one embodiment, each clamping member 380 in the two film-laying assemblies 300 can be equipped with a single clamping drive member 370 for joint driving. It is only necessary to span the two film rolls 310 with a single clamping drive member 370, thus saving one clamping drive member 370.
[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
