[0002] The manufacturing process of multi-layer ceramic chip capacitors (MLCC) includes multiple steps. Before cutting, it mainly includes the following processes: batching, casting, printing, lamination, capping and lamination.

[0046] like Figures 1 to 9 As shown, a laminating machine comprises a first unwinding shaft 1 for placing printed electrode coils,

[0047] The second unwinding roll is used to place blank tapes;

[0048] The tape cutting and material moving structure 323 includes an annular cutting knife structure 31 and a material moving structure 32, and is used to cut the printed electrode coil into square sheets, and move the square sheets to the position of the laminate structure 5, and cut the blank tape into blank sheets, and move the blank sheets to the position of the laminate structure 5;

[0049] The PET feeding structure 4 is used to feed the PET base film to the laminating structure 5.

[0050] The laminating structure 5 is provided with a lower mold 51, the cutting and transferring structure 323 moves the square sheet and the blank sheet to the upper side of the lower mold 51, and the PET feeding structure 4 moves the PET bottom film to the upper side of the lower mold 51, and the square sheet, the blank sheet and the PET bottom film are stacked in a preset order;

[0051] The cutter material transfer structure 32 is pressed with the laminated structure 5 at the upper side of the laminated structure 5, so as to press the stacked square material sheets, blank material sheets and PET base film at the upper side of the lower mold 51 of the laminated structure 5 to obtain a laminated film;

[0052] The material unloading structure is used to move the laminated film obtained by lamination to the material box.

[0053] The film to be laminated is cut into the required shape by the cutting and transferring structure 323, and then moved to the position of the lower mold 51 of the laminating structure 5. The laminating of the film is completed under the action of the laminating structure 5. At this time, during the laminating process, the cutting and transferring structure 32 is located at the upper side of the lower mold 51, and then acts as the upper mold to complete the laminating process. The cutting and transferring structure 32 has multiple functions of cutting, transferring, and laminating the upper mold, thereby simplifying the overall structure of the laminating machine, reducing equipment costs, and at the same time, improving the laminating efficiency during the laminating process.

[0054] At this time, since different materials need to be pressed together, in order to use only one cutting and transferring structure 323 and a corresponding laminating structure 5, as shown in FIG. Figure 1 and Figure 2As shown, in this embodiment, the laminate structure 5 is located in the middle of the first unloading shaft 1 and the second unloading shaft 2, and the tape cutting and material transfer structure 323 is set between the first unloading shaft 1 and the second unloading shaft 2 through a frame, and moves laterally between the first unloading shaft 1 and the second unloading shaft 2. The tape cutting and material transfer structure 323 passes through the upper side of the lower mold 51 of the laminate structure 5 during the movement. The laminate structure 5 is set in the middle of the first unloading shaft 1 and the second unloading shaft 2, and then the tape cutting and material transfer structure 323 moves back and forth between the first unloading shaft 1, the second unloading shaft 2, and the laminate structure 5, and the printed electrode coil and the blank tape are cut into square sheets and blank sheets, and moved to the position of the laminate structure 5 to complete the lamination process, thereby achieving the single structure and multifunctional effect of the tape cutting and material transfer structure 323.

[0055] The material transfer structure 32 in the strip cutting and material transfer structure 323 is mainly used to transfer the cut square pieces and blank pieces. Figures 4 to 6 As shown, in this embodiment, the material moving structure 32 includes a moving plate 321, and the moving plate 321 moves laterally on the upper side of the frame through a guide rail slider structure. The material moving structure 32 also includes a vertical moving rod 322 arranged vertically on the moving plate 321, and a lower moving plate 323 is arranged at the lower end of the vertical moving rod 322, and a pressing suction plate 324 is arranged at the lower side of the lower moving plate 323, and a plurality of adsorption holes are arranged on the lower surface of the pressing suction plate 324, and a material moving driving structure 325 for controlling the vertical moving rod 322 and the lower moving plate 323 to move up and down is arranged on the upper side of the moving plate 321. The vertical moving rod 322 and the lower moving plate 323 are controlled to move up and down by the material moving driving structure 325, so as to realize the up and down movement of the pressing suction plate 324, so as to adsorb and fix the cut square pieces and blank pieces.

[0056] Of course, the laminating machine also includes a stripping plate, which is provided with two, respectively located on the left and right sides of the pressing structure. The first unloading shaft 1 and the second unloading shaft 2 are respectively provided with printed electrode coils and blank material strips. At the same time, a first winding shaft and a second winding shaft are provided for winding up the residual material. The first unloading shaft 1, the second unloading shaft 2 and the first winding shaft and the second winding shaft are all directly driven by a servo motor 5151. In this structure directly driven by the servo motor 5151, during use, the tension feedback is sensitive and the precision is higher. The film coming out of the first unloading shaft 1 and the second unloading shaft 2 is double-layered. Therefore, it is necessary to pass through the stripping plate position first, and the corresponding film needs to be cut at the stripping plate position. After the cutting is completed, the cut square sheet and blank sheet are moved to the lower mold 51 position of the laminating structure 5 through the material transfer structure 32.

[0057] When the pressing and suction plate 324 of the material transfer structure 32 is used to move the cut square sheets and blank sheets, the square sheets and blank sheets need to be taken out at the stripping plate position first. Therefore, the pressing and suction plate 324 needs to move downward, and after adsorption, it also needs to move upward.

[0058] The up and down movement of the pressing suction plate 324 is achieved by the material moving driving structure 325. Figures 4 to 6 As shown, in the present embodiment, the material moving driving structure 325 comprises an upper top plate 3251 fixed on the upper side of the vertical moving rod 322, an elastic member 3252 is provided between the upper top plate 3251 and the moving plate 321, the elastic member 3252 is sleeved on the outer side of the vertical moving rod 322, two wedge blocks 3253 are provided on the upper side of the moving plate 321, and the inclined surfaces of the two wedge blocks 3253 are facing the middle position, and the wedge blocks 3253 move on the upper side of the moving plate 321 through the guide rail slider structure, and a protrusion 3254 is provided on the lower side of the upper top plate 3251 that abuts against the inclined surfaces of the wedge blocks 3253, when the wedge blocks 3253 move laterally, the vertical moving plate 321 moves up and down, and the material moving driving structure 325 is also provided with a motor 5151 screw rod structure for driving the two wedge blocks 3253 to move toward or away from the middle position at the same time. At this time, the movable plate 321 moves horizontally on the frame through the guide rail slider structure. Therefore, the movable plate 321 does not move in the vertical direction. At this time, the screw connected to the two wedge blocks 3253 has two sections of positive and negative threads, that is, when the motor 5151 drives the screw to rotate, the two wedge blocks 3253 move toward the middle position at the same time, or move toward the outside at the same time. During the movement of the wedge blocks 3253, the protrusions 3254 at the upper ends of the wedge blocks 3253 are also inclined. In this way, during the left and right movement of the wedge blocks 3253, the wedge blocks 3253 act on the protrusions 3254 and the upper top plate 3251, so that the upper top plate 3251 moves up and down, and then the pressing suction plate 324 fixed to the upper top plate 3251 through the vertical movable plate 321 moves up and down, so as to complete the adsorption and fixation of the square sheet and the blank sheet, and after moving to the upper side of the lower mold 51, the square sheet and the blank sheet are placed at the lower mold 51 position.

[0059] For the corresponding film to be cut into rectangles at the peeling plate position, such as Figures 4 to 6As shown, in the present embodiment, the annular cutting knife structure 31 comprises an annular movable plate 321311 at the lower side of the lower moving plate 323, the annular movable plate 321311 is located at the outer side of the pressing suction plate 324, the lower moving plate 323 is fixed with a cylinder 312, the piston rod of the cylinder 312 is fixed with an annular movable ring, and is used to control the up and down movement of the annular movable plate 321311, the annular movable plate 321311 is provided with a corresponding movable seat 313 through a guide rail slider around, a tool 314 is provided on the lower side of the movable seat 313, and the upper side of the annular movable plate 321311 is also provided with a synchronous motor 5151 and a synchronous belt, which are used to control the tool 314 to move along the guide rail direction of the guide rail slider. Specifically, the annular movable plate 321311 is located at the lower side of the lower movable plate 323, and a cylinder 312 is provided on the lower movable plate 323. The cylinder 312 is used to control the up and down movement of the annular movable plate 321311, thereby controlling the up and down movement of the movable plate 321 and the tool 314. Of course, a vertical connecting rod and a corresponding linear bearing are also provided between the annular movable plate 321311 and the lower movable plate 323, so as to realize the annular movable plate 321311 being stably positioned on the outer side of the lower movable plate 323. The tool 314 moves up and down at a certain speed. At this time, when the piston rod of the cylinder 312 is fully retracted, the lowest point of the tool 314 is higher than the lower side surface of the pressing suction plate 324 on the lower side of the lower moving plate 511, so as to avoid the tool 314 affecting the pressing suction plate 324 to adsorb and fix or put down the square sheet or blank sheet to the lower mold 51. When the piston rod of the cylinder 312 is extended, the lowest point of the tool 314 is lower than the lower side surface of the pressing suction plate 324 on the lower side of the lower moving plate 511, thereby completing the film cutting process of the tool 314 on the stripping plate.

[0060] At this time, the cutter 314 is attached to the side of the pressing and suction plate 324 , so that the film cut by the cutter 314 can correspond to the size of the pressing and suction plate 324 .

[0061] At this time, in order to cut the film into square pieces and blank pieces that can be taken out, as Figures 3 to 5As shown, in this embodiment, the annular movable plate 321311 is rectangular as a whole, and the guide rail slider is provided with four sections, which correspond to the four sides of the annular movable plate 321311 respectively. The movable seat 313 and the corresponding tool 314 are respectively provided with four, which are located at the four sides of the rectangle of the annular movable plate 321311. Four movable seats 313 and tools 314 are arranged around the annular movable plate 321311, and then they are controlled simultaneously by the synchronous motor 5151 and the synchronous belt, so that the four movable seats 313 and tools 314 move synchronously, and the trajectories of the four tools 314 form a rectangle, so that the film can be cut into corresponding rectangles. At this time, the size of the square sheet and the blank sheet obtained by cutting is highly uniform, and the size of the product obtained by pressing is also relatively uniform. At the same time, each tool 314 only needs to cut one side position and work at the same time, so that the production efficiency will be higher during the cutting process.

[0062] Furthermore, at this time, the tool 314 is located at the outer side of the pressing suction plate 324. In this way, during the operation, after the tool 314 has cut the film, it is only necessary to control the tool 314 to move upward through the cylinder 312, and control the wedge block 3253 to move outward through the driving structure (that is, the motor 5151 screw structure), so that the vertical connecting rod and the pressing suction plate 324 can move downward, so that the cut square sheet or blank sheet can be adsorbed and taken out, and then moved to the position of the lower mold 51, and the annular cutting knife structure 31 used for cutting and the material transfer structure 32 used for the cut square sheet or blank sheet can be set together, which can shorten the time for the relevant mechanism to move to the corresponding workstation, thereby improving production efficiency and reducing production costs.

[0063] After the square sheet, the blank sheet and the PET sheet are moved to the lower mold 51 of the laminate structure 5, it is necessary to complete the pressing at the lower mold 51. Figure 3As shown, in the present embodiment, the laminating structure 5 also includes a lower fixed plate 52, the upper side of the lower fixed plate 52 is connected to an upper fixed plate 53 through a column, the lower side of the lower fixed plate 52 is provided with a pressing drive structure 54, the lower mold 51 is arranged at the upper side of the lower fixed plate 52, the lower mold 51 is fixed to the pressing drive structure 54, under the action of the pressing drive structure 54, the lower mold 51 moves up and down, when the lower mold 51 moves upward to complete the pressing, the upper side of the upper top plate 3251 of the cutting and transferring structure 323 abuts against the lower side of the upper fixed plate 53, thereby completing the pressing. At this time, the pressing drive structure 54 adopts a hydraulic cylinder, and the pressure reaches 60 tons during the pressing process. Under the action of the pressing drive structure 54, the lower mold 51 moves upward. During the pressing process, the cutting and transferring structure 323 is located at the upper side of the lower mold 51, and the multi-layer film stacked on the upper side of the lower mold 51 is located between the lower mold 51 and the pressing suction plate 324. In this way, the cutting and transferring structure 323 now acts as an upper mold and is pressed with the lower mold 51, so that the stacked multi-layer film is completed.

[0064] When the cutting and transferring structure 323 acts as the transferring structure 32 to move the square sheet or the blank sheet, in order not to affect the movement of the transferring structure 32 between the two stripping plates and the lower mold 51, there is a gap between the upper top plate 3251 of the transferring structure 32 and the upper fixed plate 53 of the laminating structure 5. During the pressing process, since the cutting and transferring structure 323 is used as the upper mold as a whole, it is subjected to a greater pressure transmitted from the lower mold 51. Therefore, before pressing, it is necessary to adjust the position of the wedge block 3253 (specifically, control the wedge block 3253 to move toward the middle position) so that the upper top plate 3251 moves upward, thereby making the upper top plate 3251 move upward. The upper side of plate 3251 abuts against the lower side of the upper fixed plate 53, and then the pressing drive structure 54 controls the lower mold 51 to move upward, so that the stacked multi-layer film on the upper side of the lower mold 51 abuts against the pressing suction plate 324, thereby completing the pressing process. During the pressing process, the upward force acting on the pressing suction plate 324 is transmitted to the upper top plate 3251 through the pressing suction plate 324, the lower moving plate 323, and the vertical moving rod 322. Therefore, even if the pressure of the pressing drive structure 54 is very large, it will not affect the wedge block 3253, the movable plate, and the annular cutter structure 31, thereby ensuring that the cutting and material moving structure 323 can operate normally.

[0065] At this time, the strip cutting and material transfer structure 323 is used for cutting, material transfer and pressing the upper mold, thereby simplifying the overall equipment, reducing the production cost of the equipment, and improving the use efficiency of parts.

[0066] Furthermore, since the flatness requirement is high during the pressing process, in this embodiment, a plurality of height adjustment blocks 55 are provided on the upper side of the upper top block, and the adjustment blocks are evenly distributed on the upper side of the upper top block, and the height adjustment blocks 55 are fixed to the upper side of the upper top block by fasteners. By adjusting the position or thickness of the height adjustment blocks 55, the position of the upper top plate 3251 and the corresponding pressing suction plate 324 can be better adjusted.

[0067] The lower mold 51 is mainly used to carry the cut film. However, in the process of placing the film, there may be a deviation in the upper and lower positions. Therefore, it is necessary to make certain adjustments to the lower mold 51 to ensure the neatness of the stacked films. Figure 7 and Figure 8 In this embodiment, the lower mold 51 includes a lower movable plate 511 connected to the driving structure, an upper movable plate 512 is provided on the upper side of the lower movable plate 511 through a guide rail slider structure, a rotating plate 513 is provided on the upper side of the upper movable plate 512 through a bearing, the bearing is arranged in the middle position of the rotating plate 513, the rotating plate 513 is rotatably arranged on the upper side of the movable plate 321 with the bearing as the center, a carrying plate 514 is provided on the upper side of the rotating plate 513, a rotating driving structure 515 for driving the rotating plate 513 to rotate is also provided on the outer side of the rotating plate 513, and a lateral driving structure for driving the upper movable plate 512 to move along the guide rail slider is provided on the side of the lower movable plate 511.

[0068] Under the action of the transverse driving structure, the upper movable plate 512 can move along the guide rail direction on the upper side of the lower movable plate 511, so that the upper movable plate 512 can be adjusted laterally, and the supporting plate 514 on the upper side of the upper movable plate 512 can move laterally.

[0069] Under the action of the rotating drive structure 515, the rotating plate 513 rotates with the bearing at the center position as the center, so that the angular position of the rotating plate 513 and the upper supporting plate 514 can be adjusted. At this time, since the rotating plate 513 and the upper movable plate 512 are arranged to rotate, the main friction between the two is during use. In order to reduce the friction between the two and delay the service life, a friction plate 56 is provided between the rotating plate 513 and the upper movable plate 512. Specifically, a copper plate is used as the friction plate 56. In this way, during use, the friction loss can be reduced, thereby delaying the service life of the equipment. At this time, after adding the copper plate as the friction plate 56, since the copper plate can also withstand a certain pressure, it can also be used for pressure transmission during use.

[0070] The rotary drive structure 515 is mainly used to control the rotation of the rotary plate 513, and therefore cannot withstand the increase in the upper and lower side positions of the rotary plate 513 to avoid bearing the pressure during the pressing process. Therefore, in the present embodiment, the rotary drive structure 515 includes a motor 5151 fixed to the side of the lower movable plate 511, the shaft of the motor 5151 is connected to a transverse movable plate 5152 through a screw rod, the transverse movable plate 5152 is connected to the lower movable plate 511 through a side guide rail slider 5153, the upper side of the transverse movable plate 5152 is connected to a top adjustment plate 5155 through a top guide rail slider 5154, a rotary connecting plate 5156 is fixed to the side of the upper movable plate 512, the top adjustment plate 5155 and the rotary connecting plate 5156 are connected through a vertical shaft 5157, and the vertical shaft 5157 is respectively connected to the top adjustment plate 5155 and the rotary connecting plate 5156 through bearings.

[0071] At this time, two transition plates are provided on the side of the transverse moving plate 5152, and the two transition plates are arranged at intervals. The side of the transition plate is connected to the upper moving plate 512 through the side guide rail slider 5153 structure, and one of the transition plates is threadedly connected to the screw rod through a moving pair, so that the transverse moving plate 5152 can be controlled to move along the guide rail direction of the side guide rail slider 5153 by the motor 5151.

[0072] The top adjustment plate 5155 is connected to the upper side of the transverse moving plate 5152 through the top guide rail slider 5154, and the rotating connecting plate 5156 fixed to the rotating plate 513 is located between the two transition plates. Vertical holes are provided on the top adjustment plate 5155 and the rotating connecting plate 5156. The vertical shaft 5157 is connected at the position of the vertical hole through a bearing. The vertical shaft 5157 passes through the transverse moving plate 5152 up and down. A receiving hole larger than the outer diameter of the vertical shaft 5157 is provided at the position of the transverse moving plate 5152. When the motor 5151 drives the transverse moving plate 5152 to move through the screw rod, the transverse moving plate 5152 drives the vertical shaft 5157 to move horizontally synchronously, but at this time the transverse shaft is rotated again. The movable plate 321 is connected to the rotating plate 513, and the rotating plate 513 can only rotate. Therefore, the trajectory of the vertical axis 5157 connected to the rotating plate 513 through the rotating connecting plate 5156 must be an arc. Therefore, when the transverse movable plate 5152 moves, the top adjustment plate 5155 connected to the upper end of the vertical axis 5157 will seriously cause the lateral movement of the guide rail of the side guide rail slider 5153, as well as synchronous longitudinal movement along the guide rail direction of the top guide rail slider 5154, thereby forming an arc movement of the vertical axis 5157 at the upper end position. At this time, the accommodating hole set at the position of the transverse movable plate 5152 is set larger, and will not affect the lateral and longitudinal movement of the vertical axis 5157 with the vertical axis 5157.

[0073] At this time, the rotating driving structure 515 for driving the rotating plate 513 to rotate is set at the outer position of the rotating plate 513 and the supporting plate 514, and will not be affected by external pressure during the pressing process, thereby ensuring stability during use and avoiding damage or affecting the service life due to excessive pressure during the pressing process.

[0074] Since the pressure is relatively high during the pressing process, and the upper movable plate 512 is connected to the lower movable plate 511 through a guide rail slider, generally speaking, in order to ensure the accuracy and service life of the guide slider, the guide rail slider cannot withstand a large pressure, so the upper movable plate 512 and the lower movable plate 511 cannot be directly pressed together through the guide rail slider. In this embodiment, concave steps are provided on both sides of the upper movable plate 512, and the upper movable plate 512 is connected to the lower movable plate 511 through the guide rail slider at the position of the concave step. A moving gap is provided between the lower moving plates 511, and a floating steel sheet 516 corresponding to the slider in the guide rail slider is provided at the recessed step position of the upper moving plate 512. Both ends of the floating steel sheet 516 are fixed to the lower side surface of the upper moving plate 512 by pads, and the floating steel sheet 516 is fixed to the upper position of the slider in the guide rail slider by fasteners. When the cutter material transfer structure is pressed with the laminate structure at the upper position of the laminate structure, the floating steel sheet 516 is deformed, and the upper moving plate 512 and the lower moving plate 511 are abutted at the moving gap position. There is a moving gap between the upper movable plate 512 and the lower movable plate 511. When there is no pressing, the upper movable plate 512 and the lower movable plate 511 are connected by the guide rail slider. In this way, the movement of the upper movable plate 512 can be controlled by the lateral driving mechanism, so as to adjust the position of the upper movable plate 512 and the upper side position rotating connecting plate, the rotating plate 513, and the bearing plate 514. At the beginning of pressing, since there is a deformable floating steel sheet 516 between the upper movable plate 512 and the lower movable plate 511, the floating steel sheet 516 will be deformed at this time, thereby making the upper movable plate 512 and the lower movable plate 511 The moving gap between the movable plates 511 becomes smaller until the upper movable plate 512 and the lower movable plate 511 are completely fitted together at the original moving gap position. In this way, the contact between the upper movable plate 512 and the lower movable plate 511 is changed from the guide rail slider structure to the lower side of the upper movable plate 512. The guide rail slider structure does not bear the upper and lower pressing forces. In this way, during the pressing process, damage to the guide rail slider structure can be avoided, thereby achieving movement and pressing of the upper movable plate 512 under greater pressure. At the same time, the guide rail slider structure at this position can be protected to avoid damage during use, thereby affecting the normal use of the laminating machine.

[0075] like Fig. 9As shown, for the PET loading structure 4 and unloading structure, they are arranged at the side of the laminating structure 5, including a guide rail perpendicular to the laminating structure 5, and a loading and unloading bracket 41 moving on the upper side of the guide rail, the top of the loading and unloading bracket 41 is connected to a horizontal bracket 42 via a rotating cylinder 312 or a motor 5151, and PET film storage tables 43 and finished product collection tables 44 are respectively arranged on both sides of the horizontal bracket 42, and a suction cup plate 45 is arranged on the side of the horizontal bracket 42 close to the laminating structure 5, and the suction cup plate 45 is connected to the horizontal bracket 42 via a vertical cylinder 312 and a horizontal cylinder 312, so as to realize the horizontal movement (along the guide rail direction) and up and down movement of the suction cup plate 45, and a plurality of vacuum suction cups are arranged on the lower side of the suction cup plate 45, so as to realize the PET film being taken out from the PET film storage table 43 and moved to the upper side of the lower mold 51 of the laminating structure 5, and the pressed film after pressing is taken out from the upper side of the lower mold 51 and moved to the position of the finished product collection table 44.
