[0052] See also Figure 1-12 The present invention describes the above technical solution in detail through the following embodiments:

[0053] A device for tearing off release paper from a front camera of a mobile phone, such as Figure 1-Figure 3 The structure shown includes a work platform 2 equipped with a work protection cover 1, and also includes:

[0054] The rotating assembly 3 is rotatably mounted on the workbench 2 by a servo motor, and specifically includes a tray 31 rotatably mounted on the workbench 2, such as Figure 3 and Figure 5 As shown in the structure, in this embodiment, four evenly distributed material clamping molds 33 are installed on the tray 31 through the support plate 32, among which Figure 5 As shown, the workpiece 6 to be torn off can be clamped in the material clamping die 33, and the material can be fed in and out as the rotating component 3 rotates; and in order to maintain the accurate position of the film tearing process in this embodiment, a limit slot 311 is provided on the tray 31, and a limit electric cylinder 34 is installed on the workbench 2, and a block 341 is provided on the output shaft of the limit electric cylinder 34. When the servo motor rotates 90° each time, the corresponding block 341 is clamped into the limit slot 311, so that the tray 31 remains in position; the workpiece 6 to be torn off in this embodiment is a mobile phone, and its release paper body 61 is located at the camera position. In other embodiments, the material clamping die 33 can be adjusted according to the workpiece.

[0055] Tear off component 5, such as Figure 3 , Figure 4 and Figure 7-Figure 9 The structure shown includes a mounting base 51 fixedly mounted on the workbench 2, and specifically, the mounting base 51 includes a vertical frame leg 511 mounted with a horizontal frame 512, and a mounting back plate 513 mounted on the horizontal frame 512; it should be noted that in order to obtain the ability to adjust the height along the Z-axis, a Z-axis electric cylinder 54 is installed on the mounting back plate 513 as a Z-axis power source, wherein a vertical plate 59 is installed on the mounting back plate 513 through a connecting frame 52, and the Z-axis electric cylinder 54 serves as a power source to drive the mounting vertical plate 59 to adjust the height.

[0056] Specifically, Figure 7 and Fig. 9In the structure shown, the connecting frame 52 includes a first pad block 521 installed on the outer side of the mounting back plate 513, a vertical guide rail 5211 is provided on the first pad block 521, an intermediate plate 523 is connected to the vertical guide rail 5211 through a first slider 522 slidably installed, the intermediate plate 523 is detachably mounted with the vertical plate 59 through the second pad block 524, and the Z-axis electric cylinder 54 drives the intermediate plate 523 to rise and fall along the vertical guide rail 5211.

[0057] It should be noted that if Figure 8-Figure 12 In the structure shown in FIG. 1 , a transmission unit 56, a pressure head unit 57 and a gravity unit 58 are installed on the outer surface of the vertical plate 59; Fig.10 As shown in the positional relationship, the transmission unit 56 of this embodiment includes a tape unwinding reel 561 and a tape rewinding reel 562 rotatably mounted at the upper end of the vertical plate 59, and the pressure head unit 57 is arranged at the lower end of the vertical plate 59, and as shown in FIG. Figure 7 and Fig. 9 As shown, the vertical plate 59 is located at the rear side of the transmission unit 56 and is installed with a damper 55 and a motor 53. The damper 55 and the motor 53 are coaxially connected to the unwinding reel 561 and the taking-up reel 562 respectively, so as to stably convey the adhesive tape.

[0058] Specifically, the winding path of the tape in this embodiment is from the tape unwinding reel 561 through the pressure head unit 57 to the tape rewinding reel 562, wherein Fig.10 The structure shown is provided with a limit wheel pair 563, a first supporting wheel 564, a first limit rod 565, a side limit rod 566, a side supporting wheel 567, a second limit rod 568 and a second supporting wheel 569 in sequence for threading and installing the tape; the tape for sticking and tearing the release paper body 61 is installed and driven between the transmission unit 56, the pressure head unit 57 and the gravity unit 58; it should be noted that the supporting wheels and the limit rods on the above path are rotatably installed mainly to provide a structure for a stable moving path of the limit tape to obtain a stable conveying state. In other embodiments, the limit rods and supporting wheels can be deleted according to the actual conveying stability of the tape.

[0059] Specifically, Fig.10 and Fig.11 As shown in the structure, in this embodiment, the pressure head unit 57 is used to drive the tape to contact the release paper body 61. The pressure head unit 57 includes a mounting plate 571 mounted on the vertical plate 59. The mounting plate 571 is provided with a first vertical slide rail 572 for slidingly mounting a moving block 573. Side fixing blocks 574 for installing side supporting wheels 567 are installed on both sides of the moving block 573. A pressure head body 575 is installed between the two side fixing blocks 574 and below the moving block 573. The pressure head body 575 is provided with a guide groove 5751 for carrying the movement of the tape. The vertical plate 59 can be lifted and lowered as a whole through the action of the Z-axis electric cylinder 54, which will then drive the bottom end of the pressure head body 575 to contact the release paper body 61. In order to better adjust the height of different workpieces, such as Fig. 9As shown, a signal sensor 510 is installed below the horizontal frame 512 . In this embodiment, the signal sensor 510 is used to detect whether the release paper body 61 has adhered to the pressure head body 575 .

[0060] It should be noted that the present embodiment creatively provides a gravity unit 58, which can keep the tape in a flat and taut state; Fig.10 and Fig.12 The structure shown in the figure, the gravity unit 58 comprises a second vertical slide rail 581 fixedly mounted on the vertical plate 59, a second slider 582 is slidably mounted on the second vertical slide rail 581, a gravity block 583 and a limiting roller 584 are mounted on the upper and lower ends of the second slider 582, and the adhesive tape passes between the gravity block 583 and the limiting roller 584; the gravity unit 58 of this embodiment is installed between the second limiting rod 568 and the second roller 569, and the second limiting rod 568 and the second roller 569 are not in the same vertical direction, The gravity unit 58 is located beside the second limit rod 568 and the second support wheel 569. Its purpose is to prevent the tape from maintaining a vertical state between the second limit rod 568 and the second support wheel 569, so that the tape is in an inclined state, and then it can support the gravity unit 58 and maintain a force relationship with the gravity unit 58. The gravity of the gravity block 583 falling by itself can make the tape "tightened", making it difficult for the tape to loosen and derail, and the tape surface can be kept flat so that the release paper body 61 can be stably adhered and torn.

[0061] In this embodiment, in order to better judge whether the release paper body 61 is effectively torn off, Figure 3 , Figure 4 and Figure 6 In the structure shown in FIG. 1 , two side frame assemblies 4 are symmetrically arranged on both sides of the rotating assembly 3 and mounted on the workbench 2; the side frame assembly 4 includes a mounting vertical frame 41 on which a horizontal cross frame 42 is mounted, and a detection device 44 for determining whether a release paper body 61 exists is detachably mounted on the horizontal cross frame 42 through a mounting base plate 43, and as shown in FIG. Figure 6 In the structure shown, a barcode scanner 46 is installed on the vertical frame 41 through a crossbar 45, which can identify the batch number of each workpiece 6 to be torn off.

[0062] The mobile phone front camera release paper tearing device of this embodiment carries the workpiece 6 to be torn off through the rotating component 3. When the workpiece 6 to be torn off rotates to the bottom of the pressure head unit 57, the Z-axis electric cylinder 54 is adjusted to press down, and the tape is transported along the transmission unit 56. When it is pressed down to contact the release paper body 61, the tape sticks to the release paper body 61. Then the Z-axis electric cylinder 54 is lifted upward. The release paper body 61 itself is soft and deformable, so it can stay attached with the tape and will not fall off. It will eventually be rolled up in the take-up reel 562 to complete the operation of tearing off the release paper body 61.

[0063] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0064] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
