Description

Technical Field

[0001] The present invention relates to the technical field of soft copper pre-bending, and specifically to an automatic soft copper pre-bending device. Background Technique

[0002] The DCB process, also known as the direct copper bonding process, is a special process method for directly bonding copper foil to the surface of a ceramic substrate. The ceramic copper-clad substrate manufactured by this process has high thermal conductivity, high electrical performance, and high reliability. Therefore, it has a wide range of applications in fields such as electronic packaging and radiator manufacturing. The basic principle of the DCB process is to introduce an appropriate amount of oxygen element between copper and ceramic before or during the bonding process. Within a certain temperature range, copper and oxygen form a Cu-O eutectic liquid. The eutectic liquid can wet both the metal copper foil and the Al2O3 ceramic substrate well. After cooling to room temperature and curing, a firm bond can be formed between the two. Due to the problem of large air bubbles, softening the copper sheet first can effectively reduce the proportion of large air bubbles.

[0003] After softening the copper, pre-bending is required to make a radian in advance. To ensure the pre-bending effect, generally, the amount of copper sheets pre-bent at one time is required not to be greater than a certain value, which requires high technical requirements for manual labor; since it is difficult to separate the stacked copper sheets from each other, and the quantity needs to be counted each time, the labor intensity is high and the production efficiency is low; at the same time, due to other factors, the number of products taken during pre-bending may exceed the required value, and the pre-bending effect cannot be guaranteed.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The pre-bending equipment of the present invention adopts fully automated operation, without manual intervention, and can independently complete the entire pre-bending process. It can efficiently adjust the operation parameters of the equipment to achieve precise pre-bending effects for softened copper materials. Compared with traditional manual operations, this fully automated operation method not only greatly saves labor costs but also ensures consistent high-quality effects during the pre-bending of softened copper. It not only improves production efficiency but also reduces the possibility of human operation errors, thereby further improving the quality and consistency of products.

[0015] 2. During the loading and unloading process of softened copper, the present invention adopts a lifting method to ensure that the softened copper will not be subject to any physical compression or damage during handling. Different from the traditional suction nozzle transportation method, the traditional method transports softened copper by adsorbing it with a suction nozzle, but this method often leaves suction nozzle marks or pits on the copper surface, seriously affecting the appearance quality and subsequent processing accuracy of the softened copper, and even may lead to product scrapping. Through the lifting method, the softened copper material no longer directly contacts the equipment surface, avoiding adverse phenomena such as suction nozzle marks and pits, thus effectively protecting the integrity and quality of the softened copper surface. The lifting method is more stable and safe, effectively reducing the risk of accidental damage during transportation and improving the controllability and stability of the production process.

[0016] 3. During the process of realizing the material frame exchange, the rotating component of the present invention only needs to use one cylinder to simultaneously complete all actions of rotating, fixing, and releasing the material frame. Traditional material frame exchange methods often require multiple cylinders to work together, which not only have a complex structure, occupy a large space, but also may increase the equipment maintenance cost. Using one cylinder greatly simplifies the equipment design, reduces the manufacturing and maintenance costs. At the same time, this design reduces the coordination difficulty between moving parts, ensures the safety and stability during the operation process, and improves the operation efficiency and reliability of the equipment.

The support column 61 is installed on one side of the second linear module 53. An upper plate 62 and a lower plate 63 are installed on the support column 61. A third conveyor belt 64 is installed on the upper plate 62. A fourth conveyor belt 65 is installed on the lower plate 63. The third conveyor belt 64 and the fourth conveyor belt 65 are connected to the control system.

[0038] The working principle of the present invention:

[0039] During operation, the softened copper is transported to the first conveyor belt 22. When the softened copper is transported from the first conveyor belt 22 to the pallet 27, the control system controls the first motor to start. The first motor drives the first linear module 24 to start. The first linear module 24 drives the slide plate 25 to slide on the first linear module 24 in the direction away from the first motor. The slide plate 25 drives the U-shaped block 26 to move. The U-shaped block 26 drives the pallet 27 to move. The pallet 27 drives the softened copper to move. The pallet 27 sends the softened copper above the lower template 3405.

[0040] When the softened copper is above the lower template 3405, the cylinder rod of the lifting cylinder 3402 is controlled to extend, and the cylinder rod drives the sliding block 3403 to move, and the sliding block 3403 drives the support plate 3404 to slide in the through groove away from the lifting cylinder 3402, and the support plate 3404 lifts the softened copper until it is separated from the support plate 27, and the first motor is controlled to start, and the first motor drives the first linear module 24 to start, and the first linear module 24 drives the slide plate 25 to slide on the first linear module 24 toward the direction close to the first motor, and the slide plate 25 drives the U-shaped block 26 to move, and the U-shaped block 26 drives the support plate 27 to move to the initial position, and the cylinder rod of the lifting cylinder 3402 is controlled to be retracted, and the cylinder rod drives the support plate 3404 to be retracted to the initial position, and the support plate 3404 places the softened copper in the limit column 3407.

[0041] When the softened copper is located in the limiting column 3407, the cylinder rod of the pre-bending cylinder 3503 is controlled to extend, and the cylinder rod drives the movable plate 3504 to slide on the column 3502, and the movable plate 3504 drives the upper template 3505 to move in the direction close to the lower template 3405, until the upper arc surface 3506 is pressed on the lower arc surface 3406, and the softened copper is pre-bent. When the pre-bending of the softened copper is completed, the cylinder rod of the pre-bending cylinder 3503 is controlled to be retracted, and the cylinder rod drives the upper template 3505 to move to the initial position in the direction away from the lower template 3405, and the discharging device 4 is controlled to transport the pre-bent softened copper to the second conveyor belt 52.

[0042] When the softened copper enters the second conveyor belt 52, the second conveyor belt 52 transports the softened copper to the partition of the material frame 56. After a piece of softened copper is inserted, the second motor 54 is controlled to start, and the second motor 54 drives the second linear module 53 to start. The second linear module 53 drives the lifting block 55 to slide on the second linear module 53, and the lifting block 55 drives the rotating component 57 to move, and the rotating component 57 drives the material frame 56 to move. Every time a piece of softened copper is inserted, the lifting block 55 drives the material frame 56 to rise to a certain height until the material frame is full.

[0043] When the soft copper fills the material frame, control the second motor 54 to start. The second motor 54 drives the second linear module 53 to start. The second linear module 53 drives the lifting block 55 to slide. The lifting block 55 drives the material frame 56 to rise to the third conveyor belt 64. Control the rod of the rotary cylinder 5705 to rotate. The rod of the rotary cylinder 5705 drives the first gear 5702 to rotate. The first gear 5702 drives the second gear 5706 to rotate. The second gear 5706 drives the rotating column 5703 to rotate. The rotating column 5703 drives the T-shaped block 5704 to rotate. The T-shaped block 5704 drives the material frame 56 and the lead screw 5709 to rotate around the rotating column 5703. The lead screw 5709 drives the fourth gear 5708 to rotate around the third gear 5707. The fourth gear 5708 rotates self. The fourth gear 5708 drives the lead screw 5709 to rotate self. The lead screw 5709 drives the slider 5711 to slide on the lead screw 5709 in the direction away from the fourth gear 5708. The slider 5711 drives the limit plate 5712 to slide in the groove. The limit plate 5712 drives the connecting plate 5713 to move. The connecting plate 5713 drives the inserting plate 5714 to move. When the material frame 56 rotates to the third conveyor belt 64, the inserting plate 5714 leaves the fixed block, and the filled material frame 56 is transported out from the third conveyor belt 64.

[0044] Control the second motor 54 to start. The second motor 54 drives the second linear module 53 to start. The second linear module 53 drives the lifting block 55 to slide. The lifting block 55 drives the material frame 56 to descend to the fourth conveyor belt 65. The empty material frame 56 is transported on the fourth conveyor belt 65 to the T-shaped block 5704. Control the rod of the rotary cylinder 5705 to reverse. The rod of the rotary cylinder 5705 drives the first gear 5702 to rotate. The first gear 5702 drives the second gear 5706 to reverse. The second gear 5706 drives the rotating column 5703 to reverse. The rotating column 5703 drives the T-shaped block 5704 to reverse. The T-shaped block 5704 drives the material frame 56 and the lead screw 5709 to rotate around the rotating column 5703 in reverse. The lead screw 5709 drives the fourth gear 5708 to rotate around the third gear 5707 in reverse. The fourth gear 5708 rotates self. The fourth gear 5708 drives the lead screw 5709 to rotate self. The lead screw 5709 drives the slider 5711 to slide on the lead screw 5709 in the direction close to the fourth gear 5708. The slider 5711 drives the limit plate 5712 to slide in the groove. The limit plate 5712 drives the connecting plate 5713 to move. The connecting plate 5713 drives the inserting plate 5714 to move. When the inserting plate 5714 inserts into the fixed block, the T-shaped block 5704 just drives the material frame 56 to rotate until the empty material frame 56 rotates to the initial position and continues to start loading.
