Description

Technical Field

[0001] This utility model relates to the field of film application equipment technology, specifically to an automatic insulating film pasting machine, which is particularly suitable for the "steel pressure strip pasting insulating film" process in the field of new energy vehicle production. It can realize the automatic pasting of insulating film on the surface of workpiece without air bubbles, effectively improving production efficiency and reducing production costs. Background Technology

[0002] Steel pressure strips are fixing components for new energy vehicle batteries, and insulating films need to be pasted on their surface to meet insulation performance requirements. If the industry uses manual methods to paste insulating films onto steel pressure strips, there are several drawbacks: Firstly, manual application relies on the operator's experience and skills, making it difficult to ensure consistent application force and angle, easily leading to air bubbles between the insulating film and the steel pressure strip, affecting insulation performance and product quality stability; secondly, manual application is inefficient. With the continuous increase in new energy vehicle production, manual operation can no longer meet the needs of large-scale mass production, and rising labor costs further increase production costs for enterprises. To address the aforementioned issues, while some semi-automatic film application equipment has emerged in the market, these devices often suffer from complex structures, cumbersome operation, and the need to stop the machine for reloading during the application process. This limits continuous production and efficiency improvements, and some still struggle to completely prevent air bubbles. Therefore, developing an automated, continuous film application machine that guarantees bubble-free insulation film application can effectively improve the quality of steel pressure strip products and ensure compliance with the requirements for new energy vehicle components. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing manual labor and film-applying equipment, and to provide an insulating film applicator that enables automated and continuous production of film applicators for workpieces such as steel pressure strips, eliminates film bubbles, improves film quality, and simultaneously reduces production costs and increases production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An automatic insulating film pasting machine includes a film feeding unit, a rolling unit, and a movable support unit located below the two. The film feeding unit and the rolling unit can move horizontally synchronously and rise and fall independently. The upper surface of the movable support unit is used to place and fix the workpiece to be pasted. The film feeding unit includes a vertically arranged cross slide module, which is connected from top to bottom to a feeding tray, a receiving tray and a pressing swing arm, and the bottom end of the pressing swing arm is connected to a film application roller. The rolling unit includes a lifting element and a set of pressure rollers connected to the bottom end of the lifting element; The movable support unit includes two parallel elongated platforms, which move closer to or further away from the area directly below the film-applying roller and pressure roller assembly as they translate.

[0005] Furthermore, a main transverse slide is provided below the film feeding unit and the rolling unit, and a main transverse frame is movably connected above the main transverse slide. The film feeding unit and the rolling unit are fixed on the main transverse frame and move transversely synchronously with it.

[0006] Furthermore, a fixed free-rotating shaft is connected to the center of the feeding tray, a fixed rotary drive motor is connected to the center of the receiving tray, a fixed swing arm shaft is connected to the upper end of the pressing swing arm, and several transition rollers are provided between the swing arm shaft and the film-applying roller; the feeding tray winds the bonding body of the release film and the insulating film, the receiving tray winds the release film separated from the insulating film, and the insulating film moves down along the transition rollers to the film-applying roller after separating from the release film.

[0007] Furthermore, the lifting element is a vertically arranged downward sliding cylinder, with the telescopic movable end of the downward sliding cylinder facing downward and the bottom connected to a pressure roller frame, which is connected to the pressure roller assembly via bearings.

[0008] Furthermore, the platform's top surface has a long, narrow groove along its length to accommodate the workpiece to be coated. The bottom surfaces of the two ends of the higher-positioned platform are connected to horizontal sliding cylinders, and the bottom surface of the middle of the lower-positioned platform is also connected to a horizontal sliding cylinder. Linear guide rail modules are connected to the bottom surfaces of the two ends of the lower-positioned platform. These linear guide rail modules prevent the lower-positioned platform from bending downwards due to gravity and the pressure from the coating rollers and pressure rollers. After the workpiece is placed and fixed in the groove, the main transverse sliding table drives the coating unit and the rolling unit to move laterally, while the downward-pressing swing arm presses down. The coating rollers then apply the insulating film to the upper surface of the workpiece. During this process, the pressure rollers follow the coating rollers, and the downward-pressing sliding cylinder drives the pressure rollers to press down, ensuring a firm bond between the insulating film and the workpiece.

[0009] Furthermore, the platform length at the higher position is greater than that at the lower position, and the moving directions of the film feeding unit and the rolling unit are perpendicular to the moving direction of the platform.

[0010] Furthermore, the main transverse slide, platform, and linear guide module are all mounted on the same worktable surface, which has vertical through holes, and a movable upper support assembly is installed in the vertical through holes.

[0011] Furthermore, the movable upper support assembly includes an upper support slide cylinder, and a support plate is connected to the top of the upper movable part of the upper support slide cylinder; when the platform set at a high position moves to directly above the support plate, the support plate moves up to support the bottom surface of the platform so that its middle section is prevented from being bent and deformed by force.

[0012] Furthermore, the number of transition rollers is ≥2, and a heating fixing block and a film cutting assembly are provided between the transition roller and the film-applying roller closest to the film-applying roller.

[0013] Furthermore, the heating fixing block is equipped with a heating resistor and a temperature sensor. The adhesive strength of the insulating film increases after being heated on its surface. The film-cutting assembly includes a cutter that is pushed and moved by a cylinder. The outer surface of the heating fixing block has a cutter groove to accommodate the cutter's movement. Once the insulating film on a workpiece is pasted laterally from beginning to end, the cylinder pushes the cutter to cut the insulating film.

[0014] The beneficial effects of adopting the technical solution of this utility model are as follows: 1. The automatic insulating film pasting machine provided by this utility model achieves an automated process from film pasting to film cutting through the coordinated work of the film feeding unit, the rolling unit and the movable bearing unit. It eliminates the need for manual intervention in the film pasting process, effectively reducing labor costs and avoiding the quality instability problems caused by manual operation.

[0015] 2. The heating fixing block is used to heat the insulating film, which improves the adhesion of the insulating film. At the same time, the dual action of the initial film application by the film application roller and the secondary rolling by the pressure roller group ensures that the insulating film is tightly attached to the surface of the workpiece, suppresses the generation of air bubbles, and significantly improves the film application quality and the insulation performance of the product.

[0016] 3. The dual-platform structure is designed, and the high and low platforms can be interchanged through the flat sliding cylinder. When film application is performed on one platform, the other platform can be loaded simultaneously without stopping the machine to wait. This orderly cross-operation greatly improves production efficiency and meets the needs of large-scale mass production.

[0017] 4. By using linear guide rail modules to support both ends of the low-level platform and movable upper support components to support the middle section of the high-level platform, the bending deformation of the platform during the stress process is effectively avoided, ensuring the stability of the workpiece position during the film application process and further improving the film application accuracy.

[0018] 5. Although this utility model focuses on steel strip film application in the field of new energy vehicles, it can be adapted to workpieces of different sizes and shapes by adjusting the platform groove size, film application rollers and pressure roller group specifications, and has strong versatility.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 1-10As shown in the summary, the automatic insulating film pasting machine includes a film feeding unit 1, a rolling unit 2, and a movable support unit 3 located below them. The film feeding unit 1 and the rolling unit 2 can move horizontally synchronously and rise and fall independently. The upper surface of the movable support unit 3 is used to place and fix the workpiece to be pasted. The film feeding unit 1, the rolling unit 2, and the movable support unit 3 are all set on a worktable 6. The worktable 6 is equipped with a frame system both above and below it. The frame system adopts a profile assembly frame structure, and is equipped with casters and adjustable support feet at the bottom for easy movement and positioning of the equipment. An electrical cabinet and storage space are provided below the frame for installing control components and storing cables, providing stable support for the equipment. A main horizontal sliding table 4 is set below the film feeding unit 1 and the rolling unit 2. A main horizontal sliding frame 5 is movably connected above the main horizontal sliding table 4. The film feeding unit 1 and the rolling unit 2 are fixed on the main horizontal sliding frame 5 and move horizontally synchronously with it.

[0023] In this embodiment, the film-laying unit 1 includes a vertically arranged cross slide module 101, such as... Figure 10 The cross slide module 101 shown is a vertical combination of a set of forward and backward translational slides and a set of up and down lifting slides, enabling the film feeding unit 1 to move up and down and forward and backward. From top to bottom, the cross slide module 101 is connected to a feeding tray 102, a receiving tray 103, and a downward pressing swing arm 104. The bottom end of the downward pressing swing arm 104 is connected to a film-applying roller 107. A fixed free-rotating shaft is connected to the center of the feeding tray 102, and a fixed rotary drive motor is connected to the center of the receiving tray 103. The rotary drive motor's operating speed is adjustable, adapting to the insulation film conveying speed, ranging from 50 to 300 r / min. A fixed swing arm shaft 105 is connected to the upper end of the downward pressing swing arm 104. The swing arm shaft 105 and the film-applying roller 107 are connected... Several transition rollers 106 are arranged between the layers, with at least two transition rollers 106 in total. The feeding tray 102 winds the bonding body of the release film and the insulating film, while the receiving tray 103 winds the release film separated from the insulating film. After separation, the insulating film moves down the transition rollers 106 to the film-applying roller 107. A heating fixing block 109 and a film-cutting assembly 108 are arranged between the transition roller 106 and the film-applying roller 107, which are closest to the film-applying roller 107. The heating fixing block 109 contains a heating resistor and a temperature sensor. The heating temperature range is 40–80°C, and the temperature is monitored in real time by the temperature sensor, with a temperature control accuracy of ±2°C. The adhesive strength of the insulating film increases after being heated by the surface of the heating fixing block 109. Figure 6 , Figure 7 As shown, the film cutting assembly 108 includes a cutting blade that is pushed and moved by a cylinder. The outer surface of the heating fixing block 109 is provided with a cutting blade groove to accommodate the cutting blade moving through. When the insulating film on a workpiece is pasted, the cylinder pushes the cutting blade to move along the cutting blade groove to cut the insulating film.

[0024] Specifically, in combination Figure 1 , Figure 3As shown, the rolling unit 2 includes a lifting element and a pressure roller assembly 201 connected to the bottom of the lifting element; the lifting element is a vertically arranged downward sliding cylinder 202, the telescopic movable end of the downward sliding cylinder 202 is set downward and the bottom is connected to a pressure roller frame 203, the pressure roller frame 203 is connected to the pressure roller assembly 201 through a bearing, the pressure roller assembly 201 can press the heated insulating film onto the upper surface of the workpiece, the pressure roller is made of silicone, to ensure that the insulating film can be pressed to adhere to the workpiece without damaging the surface of the workpiece.

[0025] More specifically, in combination Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown, the movable support unit 3 includes two parallel elongated platforms 301. The platforms 301 move closer to or further away from the film-applying roller 107 and the pressure roller assembly 201 as they translate. A long, narrow groove is provided in the middle of the top surface of each platform 301 along its length to accommodate the workpiece to be film-applied. The higher platform 301 is longer than the lower platform 301. The bottom surfaces of both ends of the higher platform 301 are connected to flat-push slide cylinders 302. The worktable surface 6 has vertical through holes, and a movable upper support assembly 7 is installed in these holes. The movable upper support assembly 7 includes an upper support slide cylinder 701. The upper movable part is connected to a support plate 702 at its top. When the high-positioned platform 301 moves directly above the support plate 702, the support plate 702 moves upward to support the bottom surface of the platform 301, preventing the middle section from concave and bending. The middle bottom surface of the low-positioned platform 301 is connected to a flat-push slide cylinder 302, and the bottom surfaces at both ends of the low-positioned platform 301 are connected to linear guide rail modules 303. The linear guide rail modules 303 prevent the ends of the low-positioned platform 301 from bending downward due to gravity, the pressure of the film-applying roller 107 and the pressure roller group 201. The moving directions of the film-applying unit 1 and the rolling unit 2 are perpendicular to the moving direction of the platform 301.

[0026] The core workflow of this utility model is as follows: Material preparation: Control the front and rear translation slides in the cross slide module 101 to move the feeding tray 102, receiving tray 103 and pressing swing arm 104 forward towards the worktable 6 for easy manual operation. Load the insulating film raw material (release film and insulating film bonding body) onto the feeding tray 102, pull down the beginning of the insulating film raw material to separate the insulating film from the release film. The release film is rolled into the receiving tray 103 for recycling, while the insulating film is conveyed downward along the transition wheel 106. After loading is completed, control the front and rear translation slides to reset so that the film feeding unit 1 returns to the working position. Platform switching and loading: The moving path directly below the film-applying roller 107 and the pressure roller group 201 is the pasting area. The operation of the flat sliding cylinder 302, controlled by a pneumatic valve, moves the corresponding platform 301 to the pasting area. At the same time, another platform 301 moves in the opposite direction into the loading area. By exchanging the two platforms 301, cross-continuous switching is achieved. In the loading area, the next workpiece to be film-applied is placed in the groove on the corresponding platform 301 and fixed. When the high-positioned platform 301 is in the pasting area for film application, the upper support slide cylinder 701 of the movable upper support assembly 7 drives the support plate 702 to move upward, supporting the middle section of the bottom surface of the high-positioned platform 301 to prevent the platform 301 from concave and bending. Film application process: The heating fixing block 109 heats the passing insulating film, increasing its adhesive strength. The heated insulating film is then conveyed to the film application roller 107 to adhere to the workpiece. The main transverse slide 4 drives the film feeding unit 1 and the rolling unit 2 to move laterally. The downward pressing arm 104 is driven to press down by the telescopic cylinder hinged to it. The film application roller 107 applies the insulating film to the upper surface of the workpiece. During this process, the pressure roller group 201 follows the film application roller 107. The downward pressing slide cylinder 202 drives the pressure roller group 201 to press down, rolling the insulating film downward with appropriate pressure to ensure a firm bond between the insulating film and the workpiece, achieving "dynamic one-time bonding". The extrusion pressure also prevents air bubbles from forming at the joint surface. Cross-cycle production: After one workpiece is pasted, the main transverse frame 5 stops moving, the cylinder in the film cutting assembly 108 pushes the cutter to cut the insulating film, then the film placement unit 1 and the rolling unit 2 move and reset, the platform 301 of the pasting area moves to the loading area, the steel pressure strip that has been pasted is manually removed, and a new steel pressure strip to be pasted is placed at the same time, another platform 301 of the loading area that has been loaded with workpieces moves to the pasting area, the film placement unit 1 and the rolling unit 2 are adjusted to the matching working height according to the height of the platform 301, and the above film pasting steps are repeated to realize cyclic production.

[0027] Through the operation of this embodiment, the process of applying insulating film to steel pressure strips is automated, reducing the film application time for a single steel pressure strip from several minutes to tens of seconds, thus improving production efficiency. After film application, the insulating film adheres tightly to the steel pressure strip, and the rate of obvious bubble formation is reduced from 20% in manual operation to 0, significantly improving the product qualification rate. This effectively reduces the production cost of enterprises and meets the needs of large-scale production of new energy vehicles.

Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. Any modifications, equivalent substitutions, or improvements within the spirit and principles of this utility model should be included within its protection scope.
