[0033] The following is the attached Figure 1 To Attachment Figure 4 , describing the membrane loader 3000 according to the first aspect of the embodiment of the present invention.

[0034] Reference Figure 1 , which is a molded product formed by injection molding and pressing the diaphragm 1000 and the housing 2000 in the present invention.

[0035] Reference Figures 1 to 4A film loader 3000 of the present embodiment includes a conveying mechanism 100, a plurality of angle adjustment mechanisms 200, a plurality of fixtures 300 and a visual inspection mechanism 400. The conveying mechanism 100 is used to convey the film 1000 along a set conveying path, and a loading station, an inspection station and a material taking station are sequentially arranged along the conveying path; a plurality of angle adjustment mechanisms 200 are arranged on the conveying mechanism 100, and are used to adjust the angle of the film 1000; a plurality of fixtures 300 are respectively arranged on the corresponding angle adjustment mechanisms 200; the visual inspection mechanism 400 is arranged at the inspection station, and is used to detect the position of the film 1000.

[0036] It can be understood that in this embodiment, the membrane loader also includes a control module (not shown in the drawings), which is electrically connected to the conveying mechanism 100, the angle adjustment mechanism 200 and the visual detection mechanism 400 to drive the conveying mechanism 100, the angle adjustment mechanism 200 and the visual detection mechanism 400 to operate.

[0037] It is understandable that, referring to Figure 2 In this embodiment, the conveying mechanism 100 can realize conveying by means of a motor and a screw; specifically, the angle adjustment mechanism 200 is connected to the screw nut of the screw, and the motor is connected to one end of the screw. The motor drives the screw to rotate, thereby driving the horizontal movement of the screw nut, thereby driving the horizontal movement of the angle adjustment mechanism to convey the diaphragm.

[0038] In order to make the conveyance of the diaphragm 1000 more stable and reliable, in this embodiment, the angle adjustment mechanism 200 can also be guided by the cooperation of the slide rail and the slider to ensure the stable conveyance of the diaphragm 1000 .

[0039] Specifically, in the embodiment of the first aspect of the present invention, the conveying mechanism 100 first conveys the jig 300 to the loading station, and manually places the diaphragm 1000 in the jig 300, and then the conveying mechanism 100 conveys the diaphragm 1000 to the inspection station, the visual inspection mechanism 400 detects the position of the diaphragm 1000 and compares it with the set position, and then sends an adjustment signal to the control module, the control module sends the adjustment signal to the angle adjustment mechanism 200, and then the angle adjustment mechanism 200 receives the signal that needs to be adjusted, and drives the diaphragm 1000 to rotate a corresponding angle according to the signal. At the same time, the conveying mechanism 100 conveys the diaphragm 1000 to the material picking station. Specifically, the position of the diaphragm 1000 is detected by the visual detection mechanism 400 to determine the position of the diaphragm 1000, and the position of the diaphragm 1000 is compared with the set position to obtain the angle value that the angle adjustment mechanism 200 needs to adjust. Then, the angle adjustment mechanism 200 drives the diaphragm 1000 to adjust the corresponding angle according to the adjustment signal sent by the visual detection mechanism, so that the diaphragm 1000 is in the required material picking position, thereby ensuring the accuracy of subsequent loading of the diaphragm 1000, so that the texture of the diaphragm 1000 can accurately coincide with the texture of the outer shell 2000, thereby ensuring the production quality of the product. At the same time, when the angle adjustment mechanism 200 is in action, the conveying mechanism 100 synchronously conveys the diaphragm 1000 from the detection station to the material picking station, thereby improving the working efficiency of the equipment.

The diaphragm 1000 is manually placed in the placement cavity 310, and the placement of the diaphragm 1000 is roughly positioned by cooperating with the positioning groove 320 and the protrusion 1100, so as to facilitate manual loading and subsequent adjustment of the angle of the diaphragm 1000.

[0041] It is understandable that, referring to Figure 4 In this embodiment, a first suction component 330 is provided in the placement cavity 310. The first suction component 330 is used to suck the membrane 1000 placed in the placement cavity 310. The membrane 1000 is sucked and fixed in the placement cavity 310 by the first suction component 330 to prevent the membrane 1000 from shifting or escaping from the placement cavity during transportation, thereby ensuring stable transportation of the membrane 1000.

[0042] Specifically, in this embodiment, the first suction component 330 can achieve suction of the diaphragm 1000 through a suction head and a vacuum air source; wherein, when the diaphragm 1000 is placed in the placement cavity 310, the vacuum air source is turned on to allow the suction head to suck the diaphragm 1000, and when the diaphragm 1000 needs to be released, the vacuum air source is turned off to allow the suction head to release the diaphragm 1000.

[0043] It is understandable that, referring to Figure 3 and Figure 4 In this embodiment, the angle adjustment mechanism 200 includes a rotating component 210 and a driving component 220. The fixture 300 is arranged on the rotating component 210. The rotating component 210 is connected to the driving component 220 to drive the fixture 300 to rotate; specifically, the driving component 220 receives a signal sent by the control module, and drives the rotating component 210 to rotate a corresponding angle according to the signal, thereby driving the diaphragm 1000 to rotate a corresponding angle, so that the diaphragm 1000 accurately reaches the material picking position, thereby ensuring the subsequent accurate overlap between the diaphragm 1000 and the housing 2000.

[0044] In this embodiment, the rotating component 210 can be a rotating platform, the driving component 220 is a motor, the fixture 300 is placed on the rotating platform, and the motor is connected to the rotating platform; wherein the motor receives the signal sent by the control module, and then drives the rotating platform to rotate a corresponding angle, thereby driving the diaphragm 1000 to rotate a corresponding angle.

[0046] Specifically, the conveying mechanism 100 conveys the diaphragm 1000 to the inspection station, the CCD camera 410 takes a picture of the diaphragm 1000 and compares it with the set position of the diaphragm 1000, and then sends the compared signal to the control module, the control module sends the comparison signal to the angle adjustment mechanism 200, and drives the angle adjustment mechanism 200 to drive the diaphragm 1000 to rotate, thereby adjusting the angle of the diaphragm 1000.

[0047] It is understandable that, referring to Figure 2 In this embodiment, a plurality of in-place detection mechanisms 500 are further included. The in-place detection mechanisms 500 are respectively arranged at the loading station and the unloading station, and are used to detect whether the fixture 300 is delivered in place; specifically, the in-place detection mechanism 500 is electrically connected to the control module, and sends an in-place signal to the control module to detect whether the fixture 300 is delivered in place. In this embodiment, the in-place detection mechanism 500 can be detected by an in-place sensor.

[0048] It is understandable that, referring to Figure 2 In this embodiment, a safety grating 600 is also included, and the safety grating 600 is arranged at the loading station. The setting of the safety grating can avoid personal injury to the staff when the equipment is working. At the same time, the safety grating 600 is highly flexible, making it more convenient for the staff to load the diaphragm 1000.
