[0056] Figure 1 A schematic diagram of the structure of the support mechanism 1 provided in an embodiment of the present invention is shown. Figure 2 A schematic diagram of the structure of the foam feeding mechanism 3 provided in an embodiment of the present invention is shown. Figures 1-2 As shown, this embodiment provides a foam bonding device, which includes a foam bonding apparatus. The foam bonding apparatus includes a carrying mechanism 1, a foam feeding mechanism 3, and a foam bonding mechanism (not shown in the figure). The carrying mechanism 1 includes a carrying turntable 11 and a carrying fixture 12 disposed on the carrying turntable 11. The carrying fixture 12 can carry the screen to be bonded. A feeding station, a bonding station, and a discharging station are arranged sequentially at intervals around the carrying turntable 11. The carrying turntable 11 is rotatable and can drive the carrying fixture 12 on it to move between the stations. The foam feeding mechanism 3 is located on the bonding station and is used to carry foam. The foam bonding mechanism is disposed between the carrying mechanism 1 and the foam feeding mechanism 3. The foam bonding mechanism is configured to attach the foam on the foam feeding mechanism 3 to the surface of the screen to be bonded on the carrying fixture 12 that has moved to the bonding station.

[0057] The foam attaching device provided by the embodiment greatly reduces the size of the foam attaching device in the length direction, has a smaller floor area, and has a higher space utilization rate; when the screen body to be attached is subjected to the feeding and discharging operations on the feeding station and the discharging station, the foam attaching mechanism can perform the foam attaching operation on the screen body to be attached on the attaching station, thereby saving the standby time of the foam attaching mechanism and improving the processing efficiency of the foam attaching device; the foam feeding mechanism 3 and the foam attaching mechanism are arranged outside the carrying turntable 11, which is also beneficial to the maintenance of the air and valve devices in the foam attaching device.

[0058] Further, the carrying jig 12 is provided with a carrying groove, the profile of the carrying groove is matched with the profile of the screen body to be attached, and the groove wall of the carrying groove can be attached to the outer wall of the screen body to be attached, so as to realize the accurate positioning of the screen body to be attached.

[0059] Optionally, the carrying jig 12 is detachably connected to the carrying turntable 11. The operator can replace the carrying jig 12 according to different specifications of the screen body to be attached, so that the carrying groove of the carrying jig 12 is matched with the screen body to be attached of the corresponding specification, thereby improving the versatility of the carrying mechanism 1. Specifically, the carrying jig 12 can be connected to the carrying turntable 11 by means of bolt connection, clamping or the like, and the embodiment does not limit the detachable connection mode between the carrying jig 12 and the carrying turntable 11.

[0060] Optionally, the carrying jig 12 is further provided with a plurality of carrying suction holes arranged in an array, the carrying suction holes are communicated with the vacuum generator, and the carrying jig 12 can tightly suck the screen body to be attached through the negative pressure action of the carrying suction holes, so as to avoid the falling of the screen body to be attached when the carrying turntable 11 rotates.

[0061] Further, the carrying mechanism 1 further includes a carrying rotation driving assembly 13, the output end of the carrying rotation driving assembly 13 is connected with the carrying turntable 11, so as to drive the carrying turntable 11 to rotate. In the embodiment, the carrying rotation driving assembly 13 is specifically a carrying rotation motor.

[0062] Further, as shown in FIG. 1, the foam attaching device further includes a foam feeding mechanism 3 arranged on the carrying turntable 11, and the foam feeding mechanism 3 is arranged on the carrying turntable 11 and is matched with the carrying groove of the carrying jig 12. Figure 2As shown, the foam feeding mechanism 3 comprises a feeding base 31, a winding roller 32, a first collecting roller 33, a second collecting roller 34 and a supporting sliding plate 35. The winding roller 32, the first collecting roller 33 and the second collecting roller 34 are all rotationally arranged on the feeding base 31. The winding roller 32 is used for winding a foam assembly. The foam assembly comprises a foam, a first bottom film and a second bottom film. The first bottom film and the second bottom film are respectively attached to two sides of the foam. The first collecting roller 33 is used for winding the first bottom film. The second collecting roller 34 is used for winding the second bottom film. The supporting sliding plate 35 is slidingly arranged on the feeding base 31 to be transferred between a supporting station and a feeding station. When the supporting sliding plate 35 slides to the supporting station, it can support the foam after the foam is separated from the first bottom film and the second bottom film. When the supporting sliding plate 35 slides to the feeding station, the foam adhering mechanism can easily grab the foam carried thereon.

[0063] Optionally, a plurality of supporting suction holes arranged in an array are arranged on the supporting sliding plate 35. The supporting sliding plate 35 adsorbs the corresponding foam through the negative pressure effect of the supporting suction holes to prevent the foam from falling off when the supporting sliding plate 35 slides from the supporting station to the feeding station.

[0064] Further, a stripping piece is further arranged on the supporting sliding plate 35. The stripping piece can strip the foam from the first bottom film to prevent the foam from being wound on the first collecting roller 33 with the first bottom film. Optionally, the thickness of the stripping piece gradually decreases towards the first collecting roller 33 to facilitate the end of the stripping piece to be inserted between the foam and the first bottom film to realize the separation of the two. Optionally, the number of the stripping piece is at least two to realize the uniform and rapid separation of the foam and the first bottom film.

[0065] Since the foam has a relatively light mass, the foam separated from the first bottom film and the second bottom film is easy to fold. In order to avoid this phenomenon, the foam feeding mechanism 3 further comprises a pressing assembly 36. The pressing assembly 36 comprises a pressing cylinder and a pressing plate. The pressing cylinder is arranged on the feeding base 31. The output end of the pressing cylinder is connected with the pressing plate to drive the pressing plate to move in the vertical direction. When the supporting sliding plate 35 slides between the supporting station and the feeding station, the pressing cylinder drives the pressing plate to move upward to avoid the supporting sliding plate 35. When the supporting sliding plate 35 is located on the supporting station, the pressing cylinder drives the pressing plate to move downward to make the foam fall flat on the supporting sliding plate 35.

[0066] Optionally, at least one tensioning roller 37 is rotationally arranged between the winding roller 32 and the first collecting roller 33 and between the winding roller 32 and the second collecting roller 34 to make the foam assembly always keep a tight state during the transmission process and improve the stability of the work of the foam feeding mechanism 3.

[0067] Further, the supply base 31 comprises a first support base 311 and a second support base 312, the second support base 312 is slidingly arranged on the first support base 311, and the roll material roller 32, the first material collecting roller 33, the second material collecting roller 34, the material supporting sliding plate 35 and the pressing assembly 36 are all arranged on the second support base 312. By arranging the first support base 311 and the second support base 312 in sliding cooperation, when the roll material roller 32 needs to be replaced, the second support base 312 can be slid relative to the first support base 311 to the material replacing position to replace the roll material roller 32; and after the replacement is completed, the second support base 312 is slid relative to the first support base 311 to the material taking position, so as to facilitate the foam adhering mechanism to grab the corresponding foam from the material supporting sliding plate 35.

[0068] In the embodiment, the first support base 311 is provided with a sliding slide rail, and the second support base 312 is provided with a sliding slide block, the sliding slide block is slidingly matched with the sliding slide rail, so as to ensure the stability of the sliding process between the two. Of course, in other embodiments, the sliding slide rail can also be arranged on the second support base 312, and the sliding slide block can be arranged on the first support base 311, which can also achieve the above-mentioned effect. Optionally, limit protrusions are further arranged on both sides of the first support base 311, when the second support base 312 abuts against the limit protrusions, the second support base 312 stops sliding, so as to limit the sliding of the second support base 312, and prevent the second support base 312 from sliding off the first support base 311.

[0069] Further, a limit cylinder 313 is arranged on the first support base 311, and a limit hole is arranged on the base of the second support base 312, the output end of the limit cylinder 313 can extend into the limit hole at the bottom of the second support base 312, so as to prevent the second support base 312 from sliding when the foam adhering mechanism takes the material from the material supporting sliding plate 35, and ensure the accuracy of the material taking process.

[0070] Optionally, in the embodiment, the number of the foam supply mechanisms 3 is at least two. The at least two foam supply mechanisms 3 are arranged side by side on the adhering station. When the roll material roller 32 of one of the foam supply mechanisms 3 needs to be replaced, the foam adhering mechanism can grab the foam from the other foam supply mechanism 3, so as to save the time of stopping and waiting for the material of the foam adhering mechanism, and improve the adhering efficiency of the foam adhering device. The number of the foam supply mechanisms 3 is not limited in the embodiment, and three, four or more foam supply mechanisms can also be arranged, and the operator can adjust according to the actual production rhythm and layout space.

[0071] It should be noted that the specific structure of the foam adhering mechanism is not limited in the embodiment, and only the foam adhering mechanism which can realize the adhering of the foam on the foam supply mechanism 3 to the surface of the adhering screen body on the carrying mechanism 1 is within the protection scope of the embodiment.

[0072] In order to realize the automatic loading operation of the screen body to be attached, the foam attaching device further comprises a loading device, which is arranged at the loading station and can grab the screen body to be attached and transfer it to the carrier jig 12 circulating at the loading station. Specifically, the foam attaching device further comprises a workpiece temporary storage position, and the operator can place the screen body to be attached at the workpiece temporary storage position. The loading device is used to transfer the screen body to be attached at the workpiece temporary storage position to the carrier mechanism 1. With this arrangement, the position of the operator for loading is far away from the position of the carrier mechanism 1, which can ensure the safety of the operator and avoid the operator being injured by the foam supply mechanism 3.
