[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-7 This utility model provides a technical solution: an aluminum foil to copper foil bonding mechanism, mainly comprising a support frame 1, a first lifting drive module 2, a copper foil feeding module 3, a second lifting drive module 4, a copper foil clamping module 5, a third lifting drive module 6, an upper pressure table 7, a lower pressure table 8, and a material tray 9, etc. Specifically:
[0022] The supporting frame 1 serves as the foundation for the entire mechanism. A first lifting drive module 2 and a second lifting drive module 4 are installed on its two sides respectively. A third lifting drive module 6 and a material tray 9 are installed on the upper part. A lower pressure table 8 is installed at the bottom inside. A copper foil feeding module 3 is installed at the drive end of the first lifting drive module 2 to drive the lifting of the copper foil feeding module 3. A copper foil clamping module 5 is installed at the drive end of the second lifting drive module 4 to drive the lifting of the copper foil clamping module 5. The drive end of the third lifting drive module 6 extends into the interior of the supporting frame 1 and is equipped with an upper pressure table 7. The third lifting drive module 6 is used to drive the lifting of the upper pressure table 7. The first lifting drive module 2, the second lifting drive module 4, and the third lifting drive module 6 drive the copper foil feeding module 3, the copper foil clamping module 5, and the upper pressure table 7 to lift synchronously.
[0023] An aluminum foil 10 that can move intermittently is provided between the upper pressure table 7 and the lower pressure table 8. The material tray 9 is used to release the copper foil 11. The copper foil feeding module 3 is used to receive the copper foil 11 and can transport the copper foil 11 to the top of the aluminum foil 10. The copper foil clamping module 5 clamps the free end of the copper foil 11. The lower surface of the copper foil 11 has an adhesive layer. The third lifting drive module 6 drives the upper pressure table 7 to lift and lower, thereby cooperating with the lower pressure table 8 to press the copper foil 11 onto the surface of the aluminum foil 10. The upper pressure table 7 and the lower pressure table 8 are also used to cut the pressed copper foil 11.
[0024] The copper foil feeding module 3 includes a first base plate 31 installed at the drive end of the first lifting drive module 2. A linear guide rail 33 and a feeding guide wheel 38 are respectively installed on the upper part of the first base plate 31, and a feeding drive cylinder 32 is installed on the side. A first slide table 34 is slidably connected to the upper part of the linear guide rail 33, and the telescopic end of the feeding drive cylinder 32 is connected to the first slide table 34. A hole is pre-drilled at the top of the first slide table 34, in which a guide tongue plate 35 is installed. A locking drive cylinder 36 is installed at the top of the first slide table 34, and the telescopic end of the locking drive cylinder 36 extends into the hole and is fitted with a locking contact 37. The locking contact 37 is made of silicone or rubber and is used to protect the copper foil 11 from damage while ensuring that it can be pressed down.
[0025] The copper foil clamping module 5 includes a second base plate 51 mounted on the drive end of the second lifting drive module 4. A guide rod 52 and a clamping drive cylinder 53 are respectively mounted on the upper part of the second base plate 51. A second slide table 54 is slidably connected to the outside of the guide rod 52, and the telescopic end of the clamping drive cylinder 53 is connected to the side of the second slide table 54. A gripper cylinder 55 is mounted on the top of the second slide table 54 for clamping the free end of the copper foil 11.
[0026] A cavity 71 is pre-drilled at the bottom of the upper pressure platform 7. An electric heating rod 72 is installed inside the cavity 71 to preheat the bottom of the upper pressure platform 7 and form a hot press. A temperature sensor 73 is installed on the outer side of the bottom of the upper pressure platform 7 to detect the temperature inside the cavity 71. A U-shaped upper cutter 74 is installed on the side of the upper pressure platform 7, with its opening facing downwards, for cutting the left end of the copper foil 11.
[0027] The lower pressure table 8 corresponds to the upper pressure table 7 and is installed at the bottom of the inner side of the support frame 1. A cutting drive cylinder 81 is installed on the side of the lower pressure table 8. A "U"-shaped lower cutter 82 is installed at the telescopic end of the cutting drive cylinder 81, with the opening facing upward, for use in conjunction with the upper cutter 74 to cut the right end of the copper foil 11.
[0028] The work process is as follows:
[0029] 1. Initial preparation:
[0030] The copper foil 11 on the tray 9 is manually passed under the feed guide roller 38, then through the hole in the first slide 34, and introduced into the guide cavity of the guide tongue plate 35. When it is first inserted, the free end of the copper foil 11 needs to protrude a certain distance from the outlet of the guide tongue plate 35 so that the clamping drive cylinder 53 can clamp the free end of the copper foil 11.
[0031] Aluminum foil 10 is introduced between the upper pressure table 7 and the lower pressure table 8 by an external driving device.
[0032] 2. Copper foil feeding:
[0033] The starting mechanism, the locking drive cylinder 36 pushes the locking contact 37 downward, forming a downward pressure on the copper foil 11;
[0034] The feeding drive cylinder 32 shortens, pulling the first slide 34, guide tongue 35, locking drive cylinder 36, and locking contact 37 together to move along the linear guide rail 33 until the entire section of the guide tongue 35 enters between the upper pressure table 7 and the lower pressure table 8, that is, directly above the aluminum foil 10. During this process, the locking contact 37 generates a drag force on the copper foil 11, causing the copper foil 11 on the tray 9 to be released.
[0035] 3. Copper foil clamping:
[0036] After being moved into place, the clamping drive cylinder 53 pushes the second slide 54 and the gripper cylinder 55 together close to the upper pressure table 7 and the lower pressure table 8 until the gripper cylinder 55 clamps the protruding free end of the copper foil 11.
[0037] The locking drive cylinder 36 retracts, pulling the locking contact 37 upward, releasing the downward pressure on the copper foil 11;
[0038] When the feeding drive cylinder 32 extends, it pushes the first slide 34, the guide tongue 35, the locking drive cylinder 36, and the locking contact 37 to reset as a whole. At this time, the copper foil 11 will not move with the first slide 34, but will only stay between the upper pressure table 7 and the lower pressure table 8.
[0039] 4. Copper foil lamination and cutting:
[0040] The third lifting drive module 6 pushes the upper pressure plate 7 down until the lower surface of the upper pressure plate 7 and the upper surface of the lower pressure plate 8 press the aluminum foil 10 and copper foil 11 together. At the same time, the first lifting drive module 2 and the second lifting drive module 4 simultaneously drive the copper foil feeding module 3 and the copper foil clamping module 5 to move down synchronously. That is to say, the downward movement of the copper foil feeding module 3, the copper foil clamping module 5 and the upper pressure plate 7 are carried out synchronously. When the first lifting drive module 2 drives the copper foil feeding module 3 down, the copper foil 11 will be dragged out a small distance by the downward pressure of the upper pressure plate 7. This distance is equivalent to the part that protrudes from the outlet of the guide tongue plate 35 when the copper foil 11 was manually inserted before. It is also to prepare for the next clamping of the end of the copper foil 11 by the gripper cylinder 55.
[0041] During the process of pressing the aluminum foil 10 and copper foil 11 together by the upper pressing platform 7 and the lower pressing platform 8, the electric heating rod 72 in the upper pressing platform 7 preheats the bottom end of the upper pressing platform 7 to form hot pressing, which, combined with the adhesive layer that already exists on the lower surface of the copper foil 11, allows the copper foil 11 to be adhered to the surface of the aluminum foil 10.
[0042] As the upper pressure table 7 moves down to press down on the copper foil 11, the upper cutter 74 moves down synchronously with the upper pressure table 7. Because the height of the blade of the upper cutter 74 is higher than the height of the lower surface of the upper pressure table 7, the upper pressure table 7 presses down on the copper foil 11 first, and then the upper cutter 74 cuts off the left end of the copper foil 11.
[0043] The cutting at the right end is achieved by the upper pressure table 7 moving down to press down on the copper foil 11, and the cutting drive cylinder 81 pushing the lower cutter 82 upward, so that the blade of the lower cutter 82 abuts against the lower surface of the copper foil 11. During the abutment process, the lower surface of the upper pressure table 7 serves as a support surface, thereby achieving the cutting of the right end of the copper foil 11.
[0044] 5. Cyclic operation:
[0045] When both ends of the copper foil 11 are cut off, the cut copper foil 12 will be formed on the surface of the aluminum foil 10;
[0046] At this time, the clamping drive cylinder 53 pulls the gripper cylinder 55 to retract. During the retraction process, the gripper cylinder 55 releases the excess copper foil 11 when cutting off the right end.
[0047] An external drive device pulls the aluminum foil 10 a fixed distance. Once it is in place, the above process is repeated to complete the batch bonding of copper foil 11 to the surface of aluminum foil 10.
[0048] It should be noted that the first lifting drive module 2, the second lifting drive module 4, and the third lifting drive module 6 have the same structure, all consisting of a cylinder and a guide shaft. The extension and retraction of the cylinder pushes the copper foil feeding module 3, the copper foil clamping module 5, and the upper pressure table 7 to rise and fall. The guide shaft plays a stabilizing role. Furthermore, the control program, circuit, and pneumatic structure involved in this mechanism are all technical contents well known to those skilled in the art, and will not be described in detail here.
