Description

Technical Field

[0001] This utility model relates to the field of capacitor production technology, specifically to a laminating device for capacitor production that facilitates positioning. Background Technology

[0002] Capacitor lamination is a process that involves applying pressure and temperature (some processes require heating) to tightly bond multiple layers of materials (such as dielectric, electrode, and encapsulation layers) together to enhance the bonding force between layers, eliminate gaps and air bubbles between layers, and improve the density of the internal structure of the capacitor, thereby improving the electrical performance and stability of the capacitor.

[0003] In capacitor lamination, positioning is a crucial step in ensuring interlayer alignment accuracy and product quality. Common positioning methods involve setting baffles at the edge of the lamination platform, which have poor adjustment flexibility. When adapting to different capacitor specifications, the baffles need to be manually disassembled, installed, or adjusted, which is time-consuming and labor-intensive. Some clamping mechanisms driven by pneumatic or hydraulic systems are difficult to control in terms of pressure. Excessive pressure can damage the capacitor material, while insufficient pressure will result in poor positioning. Therefore, a lamination device for capacitor production that facilitates positioning is needed. Utility Model Content

[0004] The purpose of this invention is to provide a lamination device for capacitor production that facilitates positioning, so as to solve the problem of poor positioning effect during lamination mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laminating device for capacitor production with convenient positioning, comprising a laminating device body, a lower pressure plate, a metallized film, and a pressure groove. A base is provided at the bottom of the laminating device body, and a lower pressure plate is provided at the center of the top of the base. A metallized film is placed on the top of the lower pressure plate, and electromagnets are evenly distributed at the top of the lower pressure plate. A silicone layer is provided on the top surface of the lower pressure plate, and limiting plates are provided on both sides of the lower pressure plate via movable plates. A pressure groove is provided at the top of the laminating device body. Pressure sensors are evenly distributed on the side of the limiting plate near the metallized film. A bidirectional lead screw is provided inside the base, and movable sleeves are fitted at both ends of the bidirectional lead screw. The top ends of the movable sleeves are connected to movable plates. A drive motor is fixed at one end of the base, and the output end of the drive motor is connected to the bidirectional lead screw.

[0006] As a further technical solution of this utility model, a cylinder is fixed at the center of the top of the laminating device body, and the output end of the cylinder is connected to a lifting plate through a telescopic rod. The bottom of the lifting plate is connected to the pressing groove through fasteners.

[0007] As a further technical solution of this utility model, guide rods are provided inside the laminating device body on both sides of the lifting plate, and both sides of the lifting plate are connected to the guide rods through guide sleeves.

[0008] As a further technical solution of this utility model, a heating plate is provided at the top of the inside of the pressure groove, and a heating resistor is provided at the center of the inside of the heating plate, and a temperature sensor is provided in the heating plate on one side of the heating resistor.

[0009] As a further technical solution of this utility model, a first heat-conducting plate is provided on all four sides of the interior of the heating plate, and the first heat-conducting plate and the heating resistor are connected by a first heat-conducting rod.

[0010] As a further technical solution of this utility model, a second heat-conducting plate is provided at each of the four corners inside the heating plate, and the second heat-conducting plate and the first heat-conducting plate are connected by a second heat-conducting rod. The first heat-conducting plate, the second heat-conducting plate, the first heat-conducting rod and the second heat-conducting rod are all made of copper alloy.

[0011] As a further technical solution of this utility model, a limiting rod is provided at the bottom of the base, and a limiting sleeve is provided at the bottom of the movable sleeve.

[0012] As a further technical solution of this utility model, each end of the limiting plate is provided with a screw, and the screw passes through the movable plate. The screw and the movable plate are locked and fixed by nuts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-limit lamination device for capacitor production includes a lamination device body, a metallized film, a lower pressure plate, an electromagnet, a silicone layer, a limiting plate, a pressure sensor, a bidirectional lead screw, a movable sleeve, a drive motor, a movable plate, a pressure groove, and a cylinder. When the electromagnet is energized, it attracts the metallized film, quickly and stably fixing it to the lower pressure plate, preventing film displacement before lamination. The silicone layer is made of flexible insulating silicone, which prevents the electromagnet from scratching the metallized film during attraction. While ensuring the fixing effect, it effectively protects the surface of the metallized film from damage, ensuring the capacitor's stability. Subsequent performance remains unaffected. During lamination, the upper pressure plate presses down, and the metal film is compressed at the top, which can easily cause lateral displacement on both sides. At this time, the limiting plate can prevent this displacement, ensuring that each layer of the film maintains an accurate position during the lamination process, thus improving lamination accuracy. The pressure sensor on the limiting plate monitors the pressure between the metallized film and the limiting plate in real time. When the pressure exceeds the threshold, the drive motor drives the bidirectional lead screw to rotate in the opposite direction, increasing the gap between the limiting plate and the metal film, reducing the pressure of the limiting plate on the film, and avoiding film deformation and damage due to hard extrusion. This achieves intelligent adaptive adjustment based on the actual pressure, ensuring a safe and stable lamination process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a laminating device for capacitor production that is easy to limit, comprising a laminating device body 1, a lower pressure plate 3, a metallized film 6 and a pressure groove 7. A base 2 is provided at the bottom of the laminating device body 1, and a lower pressure plate 3 is provided at the center of the top of the base 2. The metallized film 6 is placed on the top of the lower pressure plate 3.

[0023] Electromagnets 16 are evenly distributed at the top of the interior of the lower pressure plate 3, and a silicone layer 14 is provided on the top surface of the lower pressure plate 3.

[0024] The pre-stacked metallized film 6 is placed on top of the lower pressure plate 3. The control system is activated, which energizes the electromagnet 16 inside the lower pressure plate 3, generating magnetic adsorption to fix the metallized film 6 onto the lower pressure plate 3.

[0025] The silicone layer 14 is made of flexible insulating silicone, which can prevent the electromagnet 16 from scratching the metallized film 6 during the adsorption process. While ensuring the fixation effect, it effectively protects the surface of the metallized film 6 from damage and ensures that the subsequent performance of the capacitor is not affected.

[0026] Limiting plates 15 are provided on both sides of the lower pressure plate 3 via movable plates 5. A bidirectional lead screw 12 is provided inside the base 2, and movable sleeves 13 are fitted on both ends of the bidirectional lead screw 12. The top of the movable sleeves 13 are connected to the movable plate 5. A drive motor 4 is fixed at one end of the base 2, and the output end of the drive motor 4 is connected to the bidirectional lead screw 12.

[0027] When the drive motor 4 starts, it drives the bidirectional lead screw 12 to rotate. The movable sleeve 13 on the bidirectional lead screw 12 moves along the bidirectional lead screw 12 with the cooperation of the limiting rod and the limiting sleeve, driving the movable plate 5 and the limiting plate 15 to approach the metallized film 6 until the limiting plate 15 adheres to both sides of the film, thus completing the lateral limiting of the metallized film 6.

[0028] A limit rod is provided at the bottom of the base 2, and a limit sleeve is provided at the bottom of the movable sleeve 13, which serves to guide and limit the movement of the limit plate 15.

[0029] Each of the limiting plates 15 is provided with a screw 17 at one end, and the screw 17 passes through the movable plate (5). The screw 17 and the movable plate 5 are locked together by nuts, which makes it convenient to replace the limiting plate 15.

[0030] The laminating device body 1 has a pressure groove 7 at the top, and a cylinder 9 is fixed at the center of the top of the laminating device body 1. The output end of the cylinder 9 is connected to a lifting plate 10 through a telescopic rod. The bottom of the lifting plate 10 is connected to the pressure groove 7 through fasteners.

[0031] Guide rods 11 are provided inside the laminating device body 1 on both sides of the lifting plate 10, and both sides of the lifting plate 10 are connected to the guide rods 11 through guide sleeves.

[0032] The cylinder 9 at the top of the laminating device 1 is activated, and the lifting plate 10 is pushed down along the guide rod 11 by the telescopic rod, which drives the pressing groove 7 to press down above the metallized film 6. When the pressing groove 7 contacts the metallized film 6, the cylinder 9 continues to apply pressure to laminate the metallized film 6, so that the internal multi-layer materials are tightly pressed together.

[0033] Pressure sensors 18 are uniformly arranged on the side of the limiting plate 15 near the metallized film 6. The pressure sensors 18 monitor the pressure between the metallized film 6 and the limiting plate 15 in real time.

[0034] If the pressure exceeds the preset threshold, it indicates that the metallized film 6 is deformed under pressure and may be damaged. At this time, the control system controls the drive motor 4 to drive the bidirectional lead screw 12 to rotate in the opposite direction. The movable sleeve 13 drives the movable plate 5 and the limiting plate 15 to move, increasing the gap between the limiting plate 15 and the metallized film 6, reducing the pressure of the limiting plate 15 on the metallized film 6, and realizing adaptive adjustment.

[0035] A heating plate 8 is provided at the top of the inside of the pressing groove 7, and a heating resistor 19 is provided at the center of the inside of the heating plate 8 to provide the heat required for the lamination process, so as to soften and fuse the material in the metallized film 6 at high temperature, enhance the interlayer bonding force, and at the same time cure the interlayer adhesive.

[0036] A temperature sensor 24 is installed inside the heating plate 8 on one side of the heating resistor 19 to monitor the temperature inside the heating plate 8 in real time and feed the temperature data back to the control system. The control system adjusts the heating power of the heating resistor 19 according to the preset lamination temperature parameters to achieve precise temperature control.

[0037] The heating plate 8 is provided with a first heat-conducting plate 23 on all four sides, and the first heat-conducting plate 23 and the heating resistor 19 are connected by a first heat-conducting rod 21.

[0038] A second heat-conducting plate 20 is provided at each of the four corners inside the heating plate 8, and the second heat-conducting plate 20 is connected to the first heat-conducting plate 23 by a second heat-conducting rod 22. The first heat-conducting plate 23, the second heat-conducting plate 20, the first heat-conducting rod 21 and the second heat-conducting rod 22 are all made of copper alloy.

[0039] The heat generated by the heating resistor 19 is quickly conducted to the first heat-conducting plate 23 through the first heat-conducting rod 21, and then the heat is further dispersed by the first heat-conducting plate 23. The second heat-conducting plate 20 and the second heat-conducting rod 22 transfer the heat to the four corners of the heating plate 8, making the temperature distribution of the entire heating plate 8 more uniform. The uniform temperature distribution can ensure that the metallized film 6 is heated evenly in all parts during lamination, avoiding problems such as deformation and poor interlayer bonding caused by local temperature differences, and improving the lamination quality and the performance consistency of the capacitor product.

[0040] The specific models and specifications of the drive motor 4, heating resistor 19, cylinder 9, pressure sensor 18 and electromagnet 16 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.

[0041] Working Principle: In this embodiment, the pre-stacked metallized film 6 is placed on top of the lower pressure plate 3. The control system is activated, energizing the electromagnet 16 inside the lower pressure plate 3 to magnetically attract the metallized film 6, fixing it to the lower pressure plate 3. The silicone layer 14 prevents scratches on the surface of the metallized film 6. Then, the drive motor 4 is activated, driving the bidirectional lead screw 12 to rotate. The movable sleeve 13 on the bidirectional lead screw 12 moves along the bidirectional lead screw 12 with the cooperation of the limiting rod and the limiting sleeve, driving the movable plate 5 and the limiting plate 15 to approach the metallized film 6 until the limiting plate 15 adheres to both sides of the film, completing the lateral limiting of the metallized film 6. The cylinder 9 at the top of the laminating device body 1 is activated, pushing the lifting plate 10 downward along the guide rod 11 through the telescopic rod, driving the pressing groove 7 to press down above the metallized film 6. When the pressing groove 7 contacts the metallized film 6, the cylinder 9 continues to apply pressure to laminate the metallized film 6, making the internal Multi-layer materials are tightly pressed together, and the heating plate 8 inside the pressing groove 7 starts to work. The heating resistor 19 heats up, heating the metallized film 6 during the lamination process, so that the interlayer adhesive is cured. The heat from the heating resistor 19 is evenly conducted to various areas of the heating plate 8 through the first heat-conducting plate 23, the first heat-conducting rod 21, the second heat-conducting plate 20 and the second heat-conducting rod 22, so that the heating temperature is more uniform. The temperature sensor 24 monitors the temperature in real time to ensure that the set lamination temperature is reached. The pressure sensor 18 on the limiting plate 15 monitors the pressure between the metallized film 6 and the limiting plate 15 in real time. If the pressure exceeds the preset threshold, it means that the metallized film 6 is deformed by pressure and may be damaged. At this time, the control system controls the drive motor 4 to drive the bidirectional lead screw 12 to rotate in the opposite direction. The movable sleeve 13 drives the movable plate 5 and the limiting plate 15 to move, increasing the gap between the limiting plate 15 and the metallized film 6, reducing the pressure of the limiting plate 15 on the metallized film 6, and realizing adaptive adjustment.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
