DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-7 The present invention provides a technical solution: a sheet double-sided laminating machine based on machine vision positioning, comprising a machine body 1, and also comprising:

[0044] A feeding module 2 is provided on one side of the machine body 1 and is used for feeding the sheet material;

[0045] The transfer module 3 is arranged on the machine body 1, and is used to carry the sheets fed by the feeding module 2, and to turn over the sheets during the transfer process;

[0046] The unloading module 4 is arranged on the machine body 1 and is used for unloading the sheets transferred from the transfer module 3;

[0047] The double-sided film laminating module 5 is arranged on the machine body 1 and is used for laminating the sheets before and after turning over during the sheet transfer process.

[0048] Wherein, the feeding module 2 comprises:

[0049] A loading bin 21 is provided on the machine body 1 and is used for placing sheets to be loaded;

[0050] A loading rack 22 is mounted on the machine body 1 at the transfer module 3;

[0051] A feeding slide 23 is horizontally slidable on the feeding frame 22. A feeding cylinder 24 is disposed on the feeding slide 23. A feeding suction cup 25 is disposed at the telescopic end of the feeding cylinder 24.

[0052] During the loading process, the loading slide 23 will slide on the loading rack 22 on one side of the loading bin 21 to just above the loading bin 21, and then the telescopic cylinder will extend to allow the loading suction cup 25 on it to absorb the sheet, and then the loading slide 23 will move toward the transfer module 3 to place the sheet on the transfer module 3. At the same time, the loading bin 21 is composed of a chamber and a supporting plate. After absorbing a sheet, the supporting plate will move up a certain distance so that the uppermost sheet is always at the end of the chamber. The upward movement of the supporting plate is achieved by the rotation of the threaded rod driven by the motor. In addition, the movement of the loading slide 23 can also be achieved by the rotation of the threaded rod driven by the motor to achieve the sliding of the loading slide 23 on the loading rack 22.

[0053] In addition, the transfer module 3 includes:

[0054] The feeding conveyor belt 31 and the unloading conveyor belt 32 are arranged in a ring shape and are symmetrically arranged on the machine body 1. A plurality of placement trays 33 for placing sheets are evenly arranged on the feeding conveyor belt 31 and the unloading conveyor belt 32. Notches 34 are arranged on both sides of the placement trays 33.

[0055] The flip assembly 35 is disposed between the loading conveyor belt 31 and the unloading conveyor belt 32 and is used to flip the film-laminated sheet on the loading conveyor belt 31 and place it on the unloading conveyor belt 32 for film lamination.

[0056] Meanwhile, the flip assembly 35 comprises:

[0057] The turning seat 351 is located between the loading conveyor belt 31 and the unloading conveyor belt 32 and is disposed on the machine body 1;

[0058] An electric telescopic rod 352, one end of which is rotatably arranged at the middle of the flip seat 351, and the other end of which is provided with a clamping claw 353 for clamping the sheet from the notch 34;

[0059] The turning power member 354 is disposed on the turning seat 351 and is used to drive the electric telescopic rod 352 to turn 180 degrees.

[0060] Wherein, the turning power member 354 comprises:

[0061] A connecting shaft 3541, one end of which is connected to the rotation point of the electric telescopic rod 352, and the other end of which is connected to a gear 3542;

[0062] The sector-shaped tooth plate 3543 is meshed with the gear 3542. A shaft sleeve 3544 is provided at the center of the sector-shaped tooth plate 3543. A connecting rod 3545 with a sliding groove is fixedly provided on the shaft sleeve 3544. A rotating shaft and a shaft frame for rotating the shaft sleeve 3544 are provided on the shaft sleeve 3544.

[0063] The rotating shaft 3546 slides in the sliding groove of the connecting rod 3545. The end of the rotating shaft 3546 away from the gear 3542 is provided with a connecting plate 3547. The end of the connecting plate 3547 away from the rotating shaft 3546 is provided with a rotating motor 3548 for driving the connecting plate 3547 to rotate.

[0064] When performing the flipping operation, the rotating motor 3548 drives the connecting plate 3547 to rotate, so that the rotating shaft 3546 slides in the slide groove of the connecting rod 3545, thereby driving the connecting rod 3545 to swing, thereby driving the fan-shaped toothed plate 3543 to swing, so that the gear 3542 rotates 180 degrees forward and then 180 degrees in the reverse direction, thereby realizing the 180-degree flipping of the electric telescopic rod 352. When the electric telescopic rod 352 flips to the side of the loading conveyor belt 31, the electric telescopic rod 352 drives the clamping claw 353 to extend to clamp the film-laminated sheet on the loading conveyor belt 31, and then flips 180 degrees to the placement plate 33 on the unloading conveyor belt 32, and then the electric telescopic rod 352 retracts and disengages. The plate 33 is placed to realize a sheet material transfer. At the same time, the loading conveyor belt 31 and the unloading conveyor belt 32 stop moving during the flipping and transferring process. At the same time, the loading module 2 and the unloading module 4 will perform synchronous loading and unloading operations during the stopping time, thereby speeding up the overall time of the process. In addition, through the setting of the flipping power part 354, the rotating motor 3548 can be in a state of rotational movement in one direction, avoiding the rotating motor 3548 from rotating forward and reversely, which affects the service life of the rotating motor 3548 and the invariance of switching. Therefore, through the flipping power part 354, the rotating motor 3548 can be kept in the same direction of rotation to realize the flipping of the electric telescopic rod 352.

[0065] Wherein, the double-sided film laminating module 5 comprises:

[0066] The front film laminating assembly 51 is arranged on one side of the feeding conveyor belt 31 of the machine body 1 and is used for laminating the front side of the sheet material conveyed by the feeding conveyor belt 31;

[0067] The back film pasting assembly 52 is arranged on one side of the unloading conveyor belt 32 of the machine body 1, and is used to paste film on the back side of the sheet after the flipping power member 354 transfers the sheet with the front film pasted to the unloading conveyor belt 32.

[0068] Finally, the front film assembly 51 includes:

[0069] The front film bin 511 is arranged on the machine body 1 on one side of the feeding conveyor belt 31, and is used to place the film for front film lamination on the sheet material. The arrangement and working principle of the front film bin 511 are consistent with those of the feeding bin 21;

[0070] A first vacuum film suction disk 512 is disposed directly above the front film bin 511, and a first cylinder 513 is disposed on the first vacuum film suction disk 512 for driving the first vacuum film suction disk 512 to move up and down;

[0071] A first slide 514 is mounted on the machine body 1 at the position of the front film bin 511. A first slide 515 is provided on the first slide 514 for fixing the first cylinder 513 thereon. A second cylinder 516 is provided on the first slide 515 at the transport side of the feeding conveyor belt 31. A first roller 517 is provided at the telescopic end of the second cylinder 516.

[0072] In actual operation, the first slide 515 can slide on the first slide 514 through the threaded rod and the motor. When the first slide 515 moves to the top of the front film bin, the first cylinder 513 drives the first vacuum film suction disk 512 to move downward close to the upper end of the front film bin 511, and then absorbs the film at the upper end, and then moves to the side of the upper material conveyor belt 31 to the sheet position of the upper material conveyor belt 31. Then, when the second cylinder 516 is extended, the first roller 517 is pressed down to squeeze the film onto the sheet. The loading conveyor belt 31 rotates synchronously, so that under the pressure of the first roller 517, the film is completely attached to the surface of the sheet, and the bubbles generated during the film application can be effectively removed by the roller application, so as to achieve the adhesion of the front film. After the flipping power part 354 turns the sheet over, the working principle of the back film application component 52 is the same as that of the front film application component 51, so as to achieve the film application on the back of the sheet. After the front and back of the sheet are applied, the unloading conveyor belt 32 will transfer the sheet to the position of the unloading module 4 for unloading operation. The setting of the unloading module 4 is the same as that of the loading module 2, and the reverse operation can be performed, that is, the sheet is sucked down by the vacuum suction cup, and then transferred and placed to achieve unloading;

[0073] It should be noted that the sliding of the first slide plate 515 is achieved by the rotation of the threaded rod driven by a motor. In order to achieve accurate positioning of the first slide plate 515 and move it to just above the placement tray 33 where the sheet is placed, laser rangefinders or photographic imaging devices are arranged on both sides of the loading conveyor belt 31 at the position of the first slide plate 515 to achieve machine vision positioning of the film. The first slide plate 515 is driven to slide according to the measurement and imaging results of the laser rangefinder or the photographic imaging device, so that the adsorbed film can be just aligned with the sheet below.
