Description

Technical Field

[0001] This invention relates to an automatic laminating machine. Background Technology

[0002] A laminating machine is a device that can coat films such as polyester film, metallized film, or polyolefin film to form film rolls, and is widely used in packaging and other laminating industries. Current laminating machines, during the film winding process, are prone to air bubbles and creases within the film roll due to insufficient pressure, resulting in poor film roll quality. Furthermore, when laminating multiple parts, laminating machines typically process them as a group, then cut and separate the laminated parts to obtain individual laminated parts. However, existing laminating machines require separate cutting of the parts after lamination, resulting in a limited processing method. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic laminating machine that can integrate multiple processing steps to improve production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic laminating machine, comprising:

[0005] frame;

[0007] A copper foil conveying unit, used to convey copper foil to the top or bottom of the blank section;

[0008] A coating roller press is used to press the blank portion and the copper foil together;

[0009] A separation device for cutting and holding the product formed by pressing the blank portion and copper foil together on the strip, comprising a separation mold capable of engaging;

[0010] The discharge device is used to roll up the strip containing the product.

[0011] In the optimized configuration, the conveying device includes a conveying frame mounted on the machine frame, and the film-laying rollers are respectively arranged on the conveying frame in an upper and lower position.

[0012] The optimized automatic laminating machine further includes a cutting device for punching holes in the PI film. The device includes a cutting frame mounted on the frame and located downstream of the conveying device, and a plurality of cutting sections mounted on the cutting frame. Each cutting section includes a cutting base mounted on the cutting frame, a lower cutting die and an upper cutting die mounted on the cutting base, and a cutting extension member that drives the upper cutting die to move up and down.

[0013] The optimized copper foil conveying section includes

[0014] A copper foil feeding rack is used to hold copper foil and has a through-hole for picking up the foil.

[0015] The first material handler is used to take out the copper foil from the copper foil feeding rack from the material handling port. It includes a first material handling telescopic component installed below the copper foil feeding rack and extending and retracting in the vertical direction, and a suction nozzle installed on the first material handling telescopic component and located below the material handling port.

[0016] The second material handling hand includes a gripper for holding the copper foil conveyed by the suction nozzle, a second material handling telescopic member mounted on the frame and used to drive the suction nozzle to move in a downstream direction, and a third material handling telescopic member mounted on the second material handling telescopic member and moving in a direction perpendicular to the movement of the second material handling telescopic member, wherein the gripper is mounted on the third material handling telescopic member.

[0017] The optimized coating roller press base includes a coating roller frame, a coating roller rotatably connected to the coating roller frame, a coating telescopic component that drives one of the coating rollers to move up and down to adjust the clamping force between the coating rollers, and a copper foil guide block installed on the coating roller frame and located upstream of the coating roller and downstream of the copper foil conveying section. The copper foil guide block has a guide port that runs through the upstream and downstream direction.

[0018] The optimized separation device includes a separation frame and a separation telescopic component mounted on the separation frame for driving the opening and closing of the separation mold.

[0019] In an optimized configuration, the automatic laminating machine further includes guide rollers located upstream and downstream of the cutting device, with the axis of the guide rollers being parallel to the film-laying roller.

[0020] The optimized automatic coating machine also includes a tensioning device located downstream of the separation device. The tensioning device includes at least two tensioning rollers and a pressure sensor located on the circumference of one of the tensioning rollers. The position of the tensioning roller is adjusted according to the magnitude of the tension force on the material belt sensed by the pressure sensor.

[0021] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: it realizes the automated process of copper foil lamination, improves the flatness and position of the copper foil and PI film lamination, does not produce bubbles after lamination, avoids the bubble generation after lamination by existing equipment, and the surface of the finished product after cutting is smooth and free of dirt, avoiding the dust on the surface of existing production processes and reducing several production steps.

The copper foil conveying unit 5 is used to convey copper foil to the top or bottom of the blank section; the coating roller press 6 is used to press the blank section and copper foil together; the separating device 7 is used to cut the product formed after pressing the blank section and copper foil together from the strip 0 and hold it on the strip 0, and includes a separating die that can be engaged; the tensioning device 8 is located downstream of the separating device 7, and includes a tensioning frame 82, at least two tensioning rollers 81 mounted on the tensioning frame 82, and a pressure sensor located on the circumferential surface of one of the tensioning rollers 81, and adjusts the position of the tensioning roller according to the magnitude of the tension force on the strip 0 sensed by the pressure sensor; the discharging device 9 is used to roll up the strip 0 containing the product.

[0026] Specifically, the conveying device 2 includes a conveying frame mounted on the frame 1, and film-laying rollers 21 are respectively arranged on the conveying frame in an upper and lower position.

[0027] like Figure 2As shown, the copper foil conveying unit 5 includes: a copper foil feeding rack 51 for placing copper foil, which has a vertically penetrating feeding port 52; a first feeding hand for taking out the copper foil from the feeding port 52, which includes a first feeding telescopic member 53 installed below the copper foil feeding rack and extending and retracting in the vertical direction, and a suction nozzle 54 installed on the first feeding telescopic member 53 and located below the feeding port 52; and a second feeding hand including a gripper 55 for clamping the copper foil conveyed by the suction nozzle 54, a second feeding telescopic member 56 installed on the frame 1 and for driving the suction nozzle 54 to move in the downstream direction, and a third feeding telescopic member 57 installed on the second feeding telescopic member 56 and moving in a direction perpendicular to the movement of the second feeding telescopic member 56, with the gripper 55 installed on the third feeding telescopic member 57.

The second picker sends the copper foil to the inlet. At this time, the copper foil is located between the two PI films and enters the coating roller press 6 together with the PI films. The coating roller press 6 performs hot pressing on the PI film and the copper foil, and then enters the separation device 7.
