[0005] The metal sheet and adhesive film bonding device comprises an upper die assembly and a lower die assembly, wherein the lower die assembly is provided with a punching template;

[0006] When the upper mold assembly moves in mold closing mode, the workpiece can be punched and attached to the adhesive film, and when the upper mold assembly moves in mold closing mode, the lifting mechanism can be driven to lift the adhesive film upward, so that the adhesive film is pressed against the lower surface of the punching template.

[0007] Thus, the workpiece and the adhesive film are fed in the device, and after being fed into place, the upper mold assembly moves downward to close the mold, punches the workpiece, and presses the cut workpiece onto the adhesive film, thereby realizing automatic punching and film lamination at the same station, improving production efficiency and yield, and when the workpiece is punched, the lifting mechanism can simultaneously move upward and lift the adhesive film, so that the adhesive film rests against the lower surface of the punching template, so that the workpiece can be directly dropped onto the adhesive film after punching, thereby improving the accuracy and quality of lamination.

[0008] In some embodiments, the lifting mechanism includes a plunger, a slider, and a support block;

[0009] The insert knife is connected to the upper die assembly, and the slide block is horizontally slidably connected to the lower die assembly;

[0010] The inserting knife can move downward and push the slider to move horizontally, and the slider moving horizontally pushes the supporting block to move upward.

[0011] In some embodiments, the bottom of the plunger is provided with an inclined first driving surface;

[0012] One end of the slider is provided with an inclined first driven surface, and the other end of the slider is provided with an inclined second driving surface;

[0013] The bottom of the support block is provided with an inclined second driven surface.

[0014] Thus, the first driving surface cooperates with the first driven surface, and the second driving surface cooperates with the second driven surface, so that the downward motion is converted into the horizontal motion, and then the horizontal motion is converted into the upward motion, and vice versa.

[0015] In some embodiments, the support block is drivingly connected to the slider via a tray and a panel;

[0016] The bottom of the tray is provided with a second driven surface, the tray is provided with a first embedding groove, and the embedding plate is connected to the first embedding groove;

[0019] In some embodiments, the panel is provided with a second locating pin.

[0020] Therefore, when the slider pushes the supporting block to move upward, the second positioning needle moves upward accordingly and performs positioning correction on the second material strip.

[0021] In some embodiments, the support block is provided with a limiting boss.

[0022] In some embodiments, the upper die assembly is provided with a punch, and the punching template is provided with a punching hole.

[0023] In some embodiments, the lower mold assembly is provided with a first feed channel and a second feed channel, the first feed channel passes over the punching template, and the second feed channel passes under the punching template.

[0024] In some embodiments, the first feed channel and the second feed channel are arranged perpendicular to each other.

[0025] In some embodiments, the workpieces are arranged in half-cut form on the first material strip, and the adhesive film is arranged on the second material strip.

[0026] Thus, the workpiece can be connected to the first material strip without punching, or can be arranged on the first material strip in a half-cut manner. The half-cut manner is beneficial for reducing the punching force and facilitating bonding.

[0027] Beneficial effects of the present invention: the device can perform punching and film lamination in the same station, thereby improving production efficiency and quality;

[0028] In addition, the lifting mechanism is designed to lift the film during film pasting, so that the workpiece can fall directly onto the film to avoid displacement of the workpiece, and the film can be positioned and corrected to further improve the quality of film pasting;

[0029] Furthermore, the workpieces and the film are fed through corresponding material strips, which further improves the degree of automation and production efficiency, and the workpieces are arranged in a half-cut manner on the material strip, which is conducive to improving the punching quality and film lamination quality.

[0055] Working principle:

[0056] The laminating device comprises an upper die assembly 1 and a lower die assembly 2. The upper die assembly 1 realizes die closing and die opening movements through a cylinder 4. The upper die assembly 1 is provided with a punch 11. The lower die assembly 2 is correspondingly provided with a punching template 23. The punching template 23 is provided with a punching hole 231. The lower die assembly 2 is provided with a first feed channel 21 and a second feed channel 22. The first feed channel 21 passes above the punching template 23, and the second feed channel 22 passes below the punching template 23. The workpiece is fed in the first feed channel 21 through a first material belt 5, and the adhesive film is fed in the second feed channel 22 through a second material belt 6. When the workpiece and the adhesive film are fed into place, the upper die assembly 1 is closed downward. When closing the die, the upper die assembly 1 is provided with corresponding first positioning pins to position the first material belt 5 and the second material belt 6 respectively. Then, the punch 11 punches and separates the workpiece from the first material belt 5, and presses the workpiece onto the adhesive film of the second material belt 6, thereby completing punching and laminating at the same station, thereby improving production efficiency.

[0057] In order to further improve the lamination quality, the lifting mechanism 3 can lift the film upward during lamination, reduce the distance between the film and the workpiece, and make the film abut against the lower surface of the punching template 23. After the workpiece is punched, it can be directly dropped onto the film from the punching hole 231 to avoid the workpiece from falling and shifting. The lifting mechanism 3 includes a plunger 31, a slider 32 and a support block 33. When the plunger 31 moves downward with the upper mold assembly 1, its inclined first driving surface 311 abuts against the first driven surface 321 and pushes the slider 32 to move horizontally. The second driving surface 322 of the slider 32 abuts against the second driven surface 331 at the same time and pushes the support block 33 to move upward.

[0058] The second driven surface 331 can be directly disposed on the support block 33, so that the support block 33 is directly connected to the slider 32 in a driving manner. The second driven surface 331 can also be disposed on the tray 330, and the support block 33 is indirectly driven through the structure of the tray 330 and the panel 340. The panel 340 can be provided with a second positioning pin 350, and when the support block 33 moves upward, the second material strip 6 can be positioned and corrected, thereby further improving the bonding quality.

[0059] After the punching and laminating is completed, the upper mold assembly 1 opens upward and resets, the insert knife 31 withdraws, the slider 32 can be reset under the push of a spring or other structure, the support block 33 falls back, and the corresponding material strip can continue to be fed and the above-mentioned punching and laminating action is repeated.

[0060] The workpieces can be arranged in a half-cut manner on the first material strip 5, which is beneficial to improving the punching quality and can reduce the impact force during film lamination.

[0061] The above disclosure is only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the invention.
