Description

Technical Field

[0001] This invention relates to the field of laminator technology, and particularly to a high-efficiency laminator.

Background Art

[0002] The lamination process refers to the process of firmly laminating two or more film sheets under pressure and heating conditions according to a set method. This process is widely used in the industry, and among them, MLCC and all-solid-state batteries are the fields where the lamination process is most commonly applied.

[0003] MLCC (Multi-layers Ceramic Capacitor), that is, a multilayer ceramic capacitor, is also called a laminated capacitor and is one of the most widely used capacitors. MLCC is formed by alternately laminating ceramic dielectric film sheets printed with electrodes. This process is called lamination. Then, a ceramic block is formed by high-temperature sintering, and a metal layer is formed at both ends of the block.

[0004] The lamination process of MLCC includes the following steps. That is, the lower die for lamination descends, the upper die moves away from the lamination workbench, then the upper die adsorbs the film sheet and peels the A film sheet from the wound film tape. Subsequently, the circular cutter mechanism descends to cut the film sheet into square pieces, the upper die conveys the film sheet to the lamination workbench, the lower die ascends to laminate the film sheet, and pressure holding is performed after lamination is completed.

[0005] In the manufacturing process of all-solid-state batteries, it is necessary to put the roll materials of the positive electrode sheet and the negative electrode sheet into the laminator and perform lamination in the laminator in a way that the positive electrode sheet and the negative electrode sheet are alternately arranged.

[0006] The following is an analysis of the tact time (TT) for each step in the conventional MLCC and all-solid-state battery stacking manufacturing process. The overall stacking cycle (TT) in conventional equipment is 9 seconds or more, of which the holding pressure process takes at least 3 seconds. During the holding pressure process, the upper and lower dies for stacking are pressed together by the pressure of a hydraulic cylinder, preventing the lower die from descending and the upper die from moving away from the stacking workbench. As a result, other parts of the equipment are in a standby state during this period, which significantly limits the improvement of the production efficiency of the stacking machine.

[0007] To improve the efficiency of the laminating machine, it is conceivable to place the holding pressure process in the lamination process on a separate lamination workbench and perform the holding pressure while simultaneously carrying out other lamination processes (such as the lower die's descent, the upper die's movement and detachment, the film sheet's adsorption, peeling by the peeling blade, cutting by the circular cutter mechanism, the upper die's re-importation, and the lower die's rise to start lamination). This would make it possible to shorten the overall lamination cycle (TT) to within 6 seconds, significantly reducing the lamination cycle (TT) and improving production efficiency.

[0008] One conventional method employs a "dual hydraulic cylinder" mode (including two main hydraulic cylinders, two upper molds, and one shared mobile lower mold). In this invention, "dual hydraulic cylinder" refers to a configuration consisting of two main hydraulic cylinders, or two main hydraulic cylinders combined with multiple auxiliary small hydraulic cylinders. After lamination pressurization is complete, the lower mold descends, and then a servo motor drives a ball screw mechanism to move the lower mold and the laminated ceramic block below the second upper mold (i.e., below the second hydraulic cylinder), and then the lower mold rises due to the drive of the second hydraulic cylinder to begin holding pressure. After holding pressure is complete, the lower mold is returned to below the first upper mold by the servo motor and ball screw mechanism. Simultaneously with holding pressure, the first upper mold moves away from the lamination workbench, and other lamination processes (such as film sheet adsorption, peeling by a peeling blade, cutting by a circular cutter mechanism, and subsequent re-importation of the upper mold) are executed synchronously. In this way, it becomes possible to perform the lamination process and the holding pressure process simultaneously, shortening the production cycle (TT) and improving the lamination production efficiency.

[0009] However, the "dual hydraulic cylinder" mode has the following problems. First, this mode has low frame structure rigidity, and whether a four-column or six-column structure is adopted, its structural strength and deformation are inferior to that of a single hydraulic cylinder with a four-column structure.

[0010] Furthermore, in the dual hydraulic cylinder mode, the large guide post for moving the lower die up and down is fixed to a guide post fixing plate provided on a movable straight guide rail. As such, the large guide post is movable on the straight guide rail, and its strength is significantly reduced under the high pressure of the hydraulic cylinder, making it difficult to ensure the pressure accuracy of the lamination.

[0011] Conventional MLCC and all-solid-state battery stacking machines have the following main defects: (1) In conventional laminating machines, the laminating process and the holding pressure process are carried out separately. During the holding pressure process, the upper and lower dies for lamination are pressed together by the pressure of a hydraulic cylinder, so the lower die cannot be lowered and the upper die cannot be moved and detached from the lamination workbench. As a result, during this holding pressure period, the other parts of the equipment are in standby mode, the product production cycle (TT) is lengthened, and the improvement of the production efficiency of the laminating machine is severely limited.

[0012] (2) Although the "twin cylinder" mode enables the synchronized execution of the lamination process and the holding pressure process, this mode has the problem of low frame strength, and because the large guide post, which is an important component, is fixed to a guide post fixing plate provided on a slidable straight guide rail, the large guide post is movable in the direction of the first straight slide rail, and its strength is significantly reduced under the high pressure action of the hydraulic cylinder, making it impossible to ensure lamination accuracy, and thus severely limiting its application to actual production.

[0013] To overcome the above-mentioned shortcomings, this invention innovatively introduces a "integration of two sets of single hydraulic cylinder lamination and holding pressure mechanisms." That is, two sets of single hydraulic cylinder lamination and holding pressure mechanisms (each including an upper die set, a fixed lower die set, and a hydraulic cylinder) share one set of A film supply mechanism and B film supply mechanism. As soon as the lamination process starts in the first set of single hydraulic cylinder lamination and holding pressure mechanisms, the upper die moves and detaches in the second set of single hydraulic cylinder lamination and holding pressure mechanisms, the peeling blade in the film supply mechanism moves to the peeling position, the upper die then adsorbs the film sheet and peels the film sheet from the wound film tape, the circular cutter mechanism descends and cuts the film sheet into rectangular pieces, the upper die transports the film sheet to the lamination work table, and the lower die rises to laminate the film sheet and perform holding pressure. By performing alternating operations in this manner, the lamination process and the holding pressure process can be carried out simultaneously, reducing the product production cycle (TT) and significantly improving lamination efficiency. Furthermore, the single hydraulic cylinder and fixed lower die overcome the drawbacks of the "dual hydraulic cylinder" mode, namely the low frame structure strength and low lamination accuracy. [Overview of the Initiative]

[0014] The primary objective of this invention is to provide a highly efficient laminating machine in order to solve the defects present in conventional laminating machines mentioned in the background art above.

By having the first and second sets of single hydraulic cylinder lamination and pressure holding mechanisms operate alternately in this way, other lamination processes (such as the lower die lowering, the upper die moving and detaching, the film sheet adsorption, peeling by the peeling blade, cutting by the circular cutter mechanism, the upper die being transferred, and the lower die rising to start lamination) and the pressure holding process can be performed simultaneously. This reduces the product production cycle (TT), significantly improves lamination efficiency, and overcomes the drawbacks of low frame structure strength and low lamination accuracy in the "dual hydraulic cylinder" mode by using single hydraulic cylinders and a fixed lower die.

This enables alternating operation of the film sheet taking process by the two sets of single hydraulic cylinder lamination pressure mechanisms without requiring waiting time, saving working time and significantly improving lamination efficiency.

[0033] Specifically, multiple heating rods (not shown) are embedded inside the lower mold 403 and the upper mold 404, and are used to heat the laminated film sheet.

[0035] Furthermore, the A film supply mechanism 200, the B film supply mechanism 300, and the Z-axis lifting platform are prior art and configurations well known to those skilled in the art, and are not included in the inventive features to be protected in this invention. For specific configurations, please refer to the Chinese patent document "Simplified MLCC Conveying Module Including Film Adsorption and Cutting" (Publication No.: CN118366789A). Therefore, the detailed configuration and operating principle will not be described in detail in this invention. Specifically, the operating principle and process of this invention are as follows: 1. Lamination and pressure holding of film sheets by the first single hydraulic cylinder lamination and pressure holding mechanism. In the first single-cylinder stacking and holding pressure mechanism, the lower die descends by the drive of the hydraulic cylinder, and the upper die moves out of the housing space. The A film supply mechanism is provided with a wound film tape, and a film sheet is attached to the film tape. The film sheet is transported forward by the peeling blade to the peeling position, and the A film supply mechanism and the B film supply mechanism are provided with a Z-axis lifting platform. The peeling blade rises via a ball screw mechanism by the rotation of a servo motor, and the film sheet on the peeling blade comes into contact with the lower end wall of the upper die. The upper die picks up the film sheet with vacuum suction holes, and the film tape continues to advance, peeling the film sheet from the film tape. After that, the A film sheet is cut into rectangular pieces by a circular cutter, the peeling blade descends by the Z-axis lifting platform and exits from the peeling position, and at the same time the upper die transports the cut A film sheet into the housing space of the frame, the lower die rises by the action of the hydraulic cylinder, and the lower and upper dies stack and hold pressure on the A film sheet.

[0036] 2. Lamination and pressure holding of film sheets by the second single hydraulic cylinder lamination and pressure holding mechanism. While the first single-cylinder lamination and pressure-holding mechanism is laminating and holding the film sheets, the upper die of the second single-cylinder lamination and pressure-holding mechanism moves out of the frame's housing space, the peeling blade in the A film supply mechanism moves back to the peeling position, the Z-axis lifting platform raises the peeling blade so that the film sheet on the peeling blade contacts the lower end wall of the upper die. The upper die picks up the A film sheet with vacuum suction holes, and the film tape continues to advance, peeling the film sheet from the film tape. Subsequently, the circular cutter cuts the A film sheet into rectangular pieces, the Z-axis lifting platform lowers the peeling blade and exits the peeling position, the upper die transports the cut A film sheet into the frame's housing space, the lower die rises due to the action of the hydraulic cylinder, and the lower and upper dies perform lamination and pressure-holding of the A film sheet.

[0037] While the first single-cylinder lamination and pressure-holding mechanism is performing lamination and pressure-holding of the film sheets, the upper die of the second single-cylinder lamination and pressure-holding mechanism begins to take in the film sheets. By operating the first and second single-cylinder lamination and pressure-holding mechanisms alternately in this manner, other lamination processes (such as the lower die descending, the upper die moving and detaching, the film sheet adsorption, peeling by the peeling blade, cutting by the circular cutter mechanism, the upper die being transferred, and the lower die rising to start lamination) and the pressure-holding process can be performed simultaneously. This reduces the production cycle (TT) of the product, significantly improves lamination efficiency, and overcomes the drawbacks of low frame structure strength and low lamination accuracy in the "dual-cylinder" mode by using a single hydraulic cylinder and a fixed lower die.

[0038] The advantages of this invention are as follows: (1) This invention makes it possible to carry out the lamination process and the holding pressure process simultaneously, thereby reducing the product production cycle (TT), significantly improving production efficiency, and drastically reducing lamination manufacturing costs. (2) In this invention, the lower mold is slidably connected by a guide post and a frame, and because the rigidity of the frame is high, the stacking accuracy is high, overcoming the drawbacks of low frame structural strength and inability to ensure stacking accuracy in the "dual hydraulic cylinder" mode.

[0039] While preferred embodiments of the present invention have been described above, this does not limit the scope of the patent for the present invention. Within the scope of the present invention, any equivalent modifications made based on the description and drawings of the present invention, or any application thereof directly or indirectly to other related technical fields, are all included within the scope of patent protection of the present invention.
