Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a high-efficiency laminating machine. Background Technology

[0002] The lamination process refers to the process of firmly stacking two or more films in a set pattern under pressure and heat. This process is widely used in the industry, with MLCCs and solid-state batteries being the most common applications of lamination.

[0003] MLCC (Multi-layer Ceramic Capacitor), also known as multilayer ceramic capacitor, is the most widely used type of capacitor. MLCC is formed by stacking ceramic dielectric films with printed electrodes in an alternating pattern, a process called lamination, followed by high-temperature sintering to form a ceramic block (block), and finally sealing the ends of the block with metal layers.

[0004] The MLCC lamination process includes the following steps: the lower lamination template descends, the upper template moves out of the lamination worktable, the upper template then picks up the film and peels the A film from the roll film strip, the circular knife assembly moves down and cuts the film into square pieces, the upper template transports the film to the lamination worktable, the lower template lifts up to laminate the film, and pressure is maintained after lamination is completed.

[0005] In the solid-state battery manufacturing process, a roll of positive and negative electrode materials needs to be placed into a stacking machine and stacked in the stacking machine in an alternating manner between the positive and negative electrode materials.

[0006] The analysis results of the production cycle time (TT) of each process in the existing MLCC and solid-state battery stacking process are as follows: The entire stacking cycle (TT) of the existing equipment is more than 9 seconds, of which the pressure holding part requires at least 3 seconds. During the pressure holding process, the upper and lower stacking templates are tightly pressed together under the pressure of the hydraulic cylinder. The lower stacking template cannot be lowered and the upper template cannot be removed from the stacking worktable. Therefore, other parts of the equipment can only wait during this period, which greatly limits the improvement of the production efficiency of the stacking machine.

[0007] To improve the efficiency of the laminating machine, the pressure holding process during lamination can be placed on a separate lamination worktable. While the pressure is being held, other lamination processes (including lowering of the lower template, removal of the upper template, suction of the film, stripping of the template by the peeling knife assembly, cutting of the film by the circular knife assembly, moving of the upper template in, and lifting of the lower template to start lamination) are carried out simultaneously with the pressure holding process. This can reduce the entire lamination cycle (TT) to less than 6 seconds, thereby significantly reducing the lamination cycle (TT) and improving production efficiency.

[0008] One existing method is to use a "dual-cylinder" mode (including dual cylinders, dual upper templates, and a shared moving lower template). The "dual-cylinder" referred to in this invention means using two main cylinders or two main cylinders plus several auxiliary small cylinders. After the lamination is completed, the lower template descends, and then the servo motor drives the ball screw assembly to move, causing the lower template and the lamination block to move to the bottom of the second upper template (i.e., above the second cylinder). Then, driven by the second cylinder, the lower template moves upward and begins to hold pressure under the cylinder pressure. After holding pressure, the servo motor and the ball screw drive the lower template back to the bottom of the first upper template. While holding pressure, the first upper template moves out of the lamination worktable and performs other lamination processes simultaneously, including (picking up the film, peeling the mold with the peeling knife assembly, cutting the film with the circular knife assembly, and then the upper template moves back into the lamination worktable). This allows other lamination processes and holding pressure to be performed simultaneously, reducing the production cycle (TT) and improving lamination production efficiency.

[0009] However, the "dual cylinder" mode has the following problems. First, the mold frame structure of the dual cylinder mode has poor strength. Whether the dual cylinder mode adopts a four-column structure or a six-column structure, its structural strength and deformation are far inferior to the single cylinder four-column structure.

[0010] Secondly, in the dual-cylinder mode, the large guide pillar that drives the lower template to move up and down is fixed on the guide pillar fixing plate installed on the sliding linear guide rail. The large guide pillar can move on the linear guide rail. Under the high pressure of the hydraulic cylinder, its strength is basically lost, and it is impossible to guarantee the lamination accuracy of the stack.

[0011] Existing MLCC and solid-state battery stacking machines mainly suffer from the following defects:

[0012] (1) In the existing laminating machine, the laminating process and pressure holding are carried out separately. During the pressure holding process, the upper and lower laminating templates are tightly pressed together under the pressure of the oil cylinder. The lower laminating template cannot be lowered and the upper template cannot be removed from the laminating worktable. Therefore, during the pressure holding period, other parts of the equipment can only wait idle, resulting in a long product production cycle (TT), which greatly limits the improvement of the production efficiency of the laminating machine.

[0013] (2) Although the “double cylinder” mode can realize the simultaneous operation of other processes and pressure holding in the stacking, the “double cylinder” mode not only has poor strength of the mold frame structure, but also the key component, the large guide column, is fixed on the guide column fixing plate installed on the sliding linear guide rail. The large guide column can move in the direction of the first linear guide rail. Under the high pressure of the oil cylinder, the strength of the guide column is basically lost, and the stacking accuracy cannot be guaranteed at all, which greatly limits its application in actual production.

[0014] To overcome the above-mentioned defects, this utility model innovatively introduces a "combined two single-cylinder stacking and pressure-holding mechanism" mode. That is, two single-cylinder stacking and pressure-holding mechanisms (each including an upper template, a fixed lower template, and a cylinder) share a single A diaphragm feeding mechanism and a B diaphragm material feeding mechanism. When the lamination process in the first single-cylinder stacking and pressure-holding mechanism begins lamination, the upper template in the second single-cylinder stacking and pressure-holding mechanism moves out, the peeling blade in the diaphragm feeding assembly moves to the peeling position, the upper template then picks up the diaphragm and peels it from the roll film. Then, the circular blade assembly moves down and cuts the diaphragm into square pieces. The upper template transports the diaphragm to the stacking worktable, and the lower template lifts to stack and hold pressure on the diaphragm. This alternating operation allows other lamination processes and the pressure-holding process to coexist, reducing the product production cycle (TT) and significantly improving lamination efficiency. At the same time, the single cylinder and fixed lower template overcome the defects of poor mold frame structure strength and poor lamination accuracy in the "dual-cylinder" mode.

The lower wall of the upper template can abut against the peeling blade and the upper wall of the lower template. The upper wall of the lower template and the lower wall of the upper template are respectively recessed with multiple vacuum suction holes.

[0017] Optionally, the assembly further includes a circular cutter drive motor, a rotating shaft, a short shaft, a first gear, a second gear, a synchronous pulley, a synchronous belt, a circular cutter holder, and a circular cutter.

[0018] Optionally, it also includes a second slide rail and a second slider. The second slide rail is respectively disposed on the four sides of the outer side of the lower end of the upper template.

[0019] Optionally, the device further includes guide posts and guide sleeves.

[0020] Optionally, it also includes an upper template drive motor, a lead screw, and a drive arm. The upper template drive motor is disposed on the side wall of the end of the first slide rail.

The upper template's lower end wall abuts against the stripper plate and the lower template's upper end wall, respectively. The upper and lower end walls of the lower and upper templates are respectively recessed with multiple vacuum suction holes. While the first set of single-cylinder stacking and pressure-holding mechanisms stacks and holds pressure on diaphragm A, the second set of single-cylinder stacking and pressure-holding mechanisms begins to pick up diaphragm A. The first and second sets of single-cylinder stacking and pressure-holding mechanisms operate alternately, thereby enabling other stacking processes (including lower template descent, upper template removal, diaphragm suction, stripper assembly stripping, circular blade assembly cutting, upper template insertion, lower template lifting to begin stacking, etc.) and pressure-holding processes to be carried out simultaneously. This reduces the product production cycle (TT) and significantly improves stacking efficiency. At the same time, the single cylinder and fixed lower template overcome the defects of poor mold frame structure strength and poor stacking accuracy in the "double cylinder" mode.

[0034] This utility model proposes a high-efficiency stacking machine.

[0035] Example 1

[0036] like Figures 1 to 6As shown, in this embodiment, the high-efficiency laminating machine includes a machine base 100, an A-film feeding mechanism 200, and a B-film feeding mechanism 300. The A-film feeding mechanism 200 and the B-film feeding mechanism 300 are each slidably equipped with a peeling plate 201, and the peeling plate 201 can slide up and down.

The A-film feeding mechanism 200 and the B-film feeding mechanism 300 are respectively located at the front and rear ends of the machine base 100. The pressure-holding mechanisms 400 are respectively disposed on the left and right sides of the A diaphragm feeding mechanism 200 and the B diaphragm feeding mechanism 300. The first single-cylinder stacked pressure-holding mechanism 400 and the second single-cylinder stacked pressure-holding mechanism 500 have the same structure. (It should be noted that the single-cylinder stacked pressure-holding mechanism referred to in this utility model refers to a single-cylinder stacked pressure-holding mechanism that uses one main cylinder or one main cylinder plus several auxiliary small cylinders.) Both the first single-cylinder stacked pressure-holding mechanism 400 and the second single-cylinder stacked pressure-holding mechanism 500 include a frame 401. The machine includes a hydraulic cylinder 402, a lower template 403, and an upper template 404. A frame 401 is mounted on a machine base 100. The hydraulic cylinder 402 is located at the bottom of the frame 401. A receiving cavity 4011 is provided in the middle of the frame 401. The lower template 403 is slidably mounted on the bottom of the receiving cavity 4011. The lower end of the lower template 403 is fixedly connected to the piston rod of the hydraulic cylinder 402. The machine also includes a first slide rail 405 and a first slider 406. Both ends of the first slide rail 405 extend into the receiving cavity 4011 and are connected to the frame 401. The upper end of the upper part is fixedly connected on both sides. The first slider 406 is slidably connected to the first slide rail 405. The two sides of the upper template 404 are fixedly connected to the first slider 406 respectively. The upper template 404 can be slidably arranged in the accommodating cavity 4011. The upper end of the upper template 404 can abut against the upper end wall of the accommodating cavity 4011. The lower end wall of the upper template 404 can abut against the upper end wall of the peeling plate 201 and the lower template 403 respectively. The upper end wall of the lower template 403 and the lower end wall of the upper template 404 are respectively recessed with multiple vacuum suction holes (not shown).

[0037] Specifically, such as Figure 4-6As shown, it also includes a circular cutter drive motor 407, a rotating shaft 408, a short shaft 409, a first gear 410, a second gear 411, a synchronous pulley 412, a synchronous belt 413, a circular cutter holder 414, and a circular cutter 415. The circular cutter drive motor 407 is located at the top corner of the upper end of the upper template 404. The rotating shaft 408 is rotatably located at the top corner of the upper template 404. The short shafts 408 are respectively located at the top corners of the lower end wall of the upper template 404. The first gear 410 is located on the output shaft of the circular cutter drive motor 407, and the second gear 411 is located at the upper end of the rotating shaft 408. The first gear 410 and the second gear 411 mesh with each other. Next, synchronous pulleys 412 are respectively disposed at the lower ends of rotating shaft 408 and short shaft 409. Synchronous pulleys 412 and short shaft 409 are rotatably connected. Synchronous belts 413 are respectively meshed with synchronous pulleys 412. Circular knife holders 414 are slidably disposed on the four outer sides of the lower end of upper template 404. Circular knife holders 414 are respectively fixedly connected to synchronous belts 413. Circular knives 415 are rotatably disposed on the inner side of the lower end of circular knife holders 414. Circular knives 415 are parallel to the four sides of upper template 404, so that the circular knives can slide simultaneously along the four sides of lower template, thereby achieving simultaneous cutting of the stacked film around its perimeter through the circular knives.

[0038] Specifically, such as Figure 4-6 As shown, it also includes a second slide rail 416 and a second slider 417. The second slide rail 416 is respectively disposed on the four sides of the outer side of the lower end of the upper template 404. The second slider 417 is slidably connected to the second slide rail 416. The circular knife holder 414 is fixedly connected to the second slider 417 and plays a guiding role for the circular knife holder.

[0039] Specifically, such as Figure 3 As shown, it also includes guide posts 418 and guide sleeves 419. The guide posts 418 are respectively disposed at the bottom of the accommodating cavity 4011, and the guide sleeves 419 are respectively embedded at the four top corners of the lower template 403.

[0040] Specifically, such as Figure 3As shown, it also includes an upper template drive motor 421, a lead screw 422, and a drive arm 423. The upper template drive motor 421 is respectively set on the side walls of both ends of the first slide rail 405. The two ends of the lead screw 422 are rotatably connected to the side walls of the first slide rail 405, and one end of the lead screw 422 is connected to the output shaft of the upper template drive motor 421. A nut 420 is embedded in the lower end of the drive arm 423. The nut 420 is screwed on the lead screw 422. The upper end of the drive arm 423 is fixedly connected to the upper template 404. The upper template is driven to slide along the left and right directions of the first slide rail by the upper template drive motor and the lead screw. While the first single-cylinder stacking and pressure holding mechanism is stacking and pressure holding, the upper template of the second single-cylinder stacking and pressure holding mechanism continues to pick up the mold pieces without waiting. This realizes the alternating film picking process of the two sets of single-cylinder stacking and pressure holding mechanisms, saving time and greatly improving the stacking efficiency.

[0041] Specifically, multiple heating rods (not shown) are embedded in the lower template 403 and the upper template 404 to facilitate heating of the laminated film.

[0042] Example 2

[0043] The difference between this embodiment and Implementation 1 is that:

[0044] like Figure 7 As shown, the hydraulic cylinder 402 is located on the top of the frame 401, and the upper template 404 is slidably located on the top of the accommodating cavity 4011. The lower end of the upper template 404 is fixedly connected to the piston rod of the hydraulic cylinder 402. The two sides of the lower template 403 are fixedly connected to the first slider 406 respectively. The lower template 403 can slide along the accommodating cavity 4011. The lower end of the lower template 403 can abut against the lower end wall of the accommodating cavity 4011. The lower end wall of the lower template 403 can abut against the peeling plate 201 and the upper template 404 respectively.

[0045] It should be emphasized that the A diaphragm feeding mechanism 200, the B diaphragm feeding mechanism 300, and the Z-axis lifting platform are existing technologies and are structures well known to those skilled in the art. They are not the inventive points to be protected by this utility model. For the specific structure, please refer to Chinese Invention Patent: A Simplified MLCC Handling Module with Diaphragm Suction and Cutting, Publication No.: CN118366789A. Therefore, its detailed structure and working principle will not be described in detail in this utility model.

[0046] Specifically, the working principle and process of this utility model are as follows:

[0047] 1. The first single-cylinder stacking and pressure-holding mechanism stacks and holds pressure on the diaphragm.

[0048] In the first single-cylinder stacking and pressure-holding mechanism, the lower template is driven to descend by a hydraulic cylinder, and the upper template moves out of the accommodating cavity. The A-film feeding mechanism is equipped with a rolled material strip with a film attached to it. The peeling plate moves the film forward to the peeling position. The A-film feeding mechanism and the B-film feeding mechanism are equipped with a Z-axis lifting platform. The servo motor rotates and drives the peeling plate to rise through the ball screw assembly, so that the film on the peeling plate abuts against the lower end wall of the upper template. The upper template adsorbs the film through the vacuum suction hole. The material strip continues to move forward and peels the film off the material strip. Then, the A-film is cut into square pieces by a circular knife. The Z-axis lifting platform drives the peeling plate to descend and the peeling plate retracts from the peeling position. At the same time, the upper template moves the cut A-film into the accommodating cavity of the frame. The lower template rises under the action of a hydraulic cylinder. The A-film is stacked and pressure-held by the lower template and the lower template.

[0049] 2. The second single-cylinder stacking and pressure-holding mechanism stacks and holds pressure on the diaphragm.

[0050] While the first set of single-cylinder stacking and pressure-holding mechanisms stacks and holds pressure on the diaphragm, the upper template in the second set of single-cylinder stacking and pressure-holding mechanisms moves out of the accommodating cavity of the frame. The peeling plate in the A-diaphragm feeding mechanism moves back to the peeling position. The Z-axis lifting platform drives the peeling plate to rise, so that the diaphragm on the peeling plate abuts against the lower end wall of the upper template. The upper template adsorbs the A-diaphragm through the vacuum suction hole. The material belt continues to move forward and peels the diaphragm off the material belt. Then, the A-diaphragm is cut into square pieces by a circular knife. The Z-axis lifting platform drives the peeling plate to fall, and the peeling plate exits the peeling position. At the same time, the upper template moves the cut A-diaphragm into the accommodating cavity of the frame. The lower template rises under the action of the hydraulic cylinder. The A-diaphragm is stacked and pressure-held by the lower template and the lower template.

[0051] While the first single-cylinder stacking and pressure-holding mechanism stacks and holds pressure on the diaphragm, the upper template of the second single-cylinder stacking and pressure-holding mechanism begins to remove the diaphragm. The first and second single-cylinder stacking and pressure-holding mechanisms operate alternately, thereby enabling other stacking processes (including lower template descent, upper template removal, diaphragm removal, stripping assembly for demolding, circular knife assembly for cutting the diaphragm, upper template insertion, and lower template lifting to begin stacking) and pressure-holding processes to be carried out simultaneously. This reduces the product production cycle (TT) and significantly improves stacking efficiency. At the same time, the single cylinder and fixed lower template overcome the defects of poor mold frame structure strength and poor stacking accuracy in the "double cylinder" mode.

[0052] The advantages of this utility model are:

[0053] (1) This utility model enables the simultaneous execution of other lamination processes and pressure holding processes, reduces the product production cycle (TT), significantly improves production efficiency, and greatly reduces the production cost of lamination;

[0054] (2) The lower template of this utility model is connected to the guide column and the frame by sliding. The frame has high strength, which makes the stacking accuracy high and overcomes the defects of poor strength of the "double oil cylinder" mode template frame structure and the inability to guarantee the stacking accuracy.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
