Description

Technical Field

[0001] This utility model is a film application table with a film separation component, belonging to the field of film application table technology. Background Technology

[0002] In the automotive audio manufacturing industry, applying protective or decorative films to the speaker housing surface is a critical process that directly impacts the product's wear resistance, acoustic performance (such as vibration noise suppression and frequency response optimization), and appearance consistency. This process requires the diaphragm to be uniformly bonded to complex curved surfaces (such as the curved surface of the housing) without bubbles or wrinkles, with a bonding accuracy controlled within ±50μm to avoid acoustic distortion or aesthetic defects. However, the protective film covering the diaphragm surface must be removed before application; this step is crucial for the subsequent bonding quality.

[0003] In current production, the separation of protective film is highly dependent on manual operation. Operators need to manually peel off the protective film, which is time-consuming and difficult. Especially at the separation edge, because the protective film is extremely thin, it is very difficult to peel it off the edge quickly. The separation time for a single piece exceeds 2 minutes, which is inefficient and seriously restricts the efficiency and quality stability of mass production of car audio equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a film application stage with a film separation component to solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A film application station with a film separation assembly includes: a worktable and a film placed on the worktable; A support seat slidably disposed on one side of the workbench, a first drive assembly for driving the support seat to move laterally, a first negative pressure assembly disposed above the support seat, and a second drive assembly for driving the first negative pressure assembly to rise and fall. A second negative pressure component is embedded and installed on the upper surface of the worktable, the second negative pressure component being located below the diaphragm; It also includes a control module, which is electrically connected to the first drive component, the second drive component, the first negative pressure component, and the second negative pressure component. The control module controls the first drive component to drive the support seat to move laterally toward one side of the worktable, so that the first negative pressure component is located directly above the second negative pressure component. In cooperation with the second drive component, the first negative pressure component is driven to move downward until it is in contact with the upper surface of the diaphragm. The control module synchronously controls the activation of the first negative pressure component and the second negative pressure component. The first negative pressure component adsorbs the protective film attached to the top of the membrane, and the second negative pressure component adsorbs the bottom of the membrane. The second driving component controls the first negative pressure component to move upward and separate the protective film on the membrane.

[0006] As a further improvement, the first drive assembly includes a motor installed inside the worktable and a gear installed at one end of the motor drive shaft. The support base includes a rack that is slidably inserted into the worktable, the rack meshing with a gear on its upper part, and a base integrally provided on the outer end of the rack, and the second drive assembly is installed on the base.

[0007] As a further improvement, the workbench is provided with a receiving cavity, which includes a first cavity for accommodating the motor and a second cavity for accommodating the rack. The first cavity is cylindrical and the second cavity is elongated.

[0008] As a further improvement, the second drive assembly includes an electric push rod vertically mounted on the base, with an auxiliary plate fixedly mounted on the top of the electric push rod, and the first negative pressure assembly disposed below the auxiliary plate.

[0009] As a further improvement, the auxiliary plate is made of metal, and the bottom of the auxiliary plate is fixed to the top of the electric push rod by welding.

[0010] As a further improvement, the first negative pressure assembly includes a first negative pressure adsorption nozzle inserted and fixed below the auxiliary plate, the first negative pressure adsorption nozzle being connected to an external air pump.

[0011] As a further improvement, the first negative pressure adsorption nozzle is provided with several independent adsorption channels for precisely adsorbing the protective film edge of the membrane.

[0012] As a further improvement, the second negative pressure assembly includes a second negative pressure suction nozzle embedded in and mounted on the surface of the workbench, the top of the second negative pressure suction nozzle being flush with the workbench, and the second negative pressure suction nozzle being connected to an external air pump.

[0013] As a further improvement, the second negative pressure assembly also includes a pressure sensor disposed on one side of the second negative pressure suction nozzle, which detects the downward pressure state of the first negative pressure suction nozzle.

[0014] Beneficial effects: This invention achieves precise and rapid separation of the protective film edge by adopting a negative pressure collaborative control mechanism, shortening the separation time to within 5 seconds, making it convenient for operators to further peel off all the protective film.

[0015] After the operator places the diaphragm with protective film on the workbench, the control module is activated, driving the first drive component to move the support seat laterally and positioning the first negative pressure component directly above the diaphragm. The second drive component simultaneously presses down on the first negative pressure component, causing it to adhere to the upper surface of the membrane. Then, the control module precisely and synchronously activates both the first negative pressure component (adsorbing the protective film) and the second negative pressure component (adsorbing the membrane substrate), and lifts the first negative pressure component via the second drive component, achieving stress-free peeling of the protective film's edges. The separation time is reduced to within 5 seconds, facilitating the operator to further remove all protective films. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Reference Figure 1-9 As shown, a film application table with a film separation assembly includes: a worktable 1 and a film 2 placed on the worktable 1; A support base 3 is slidably disposed on one side of the workbench 1, a first drive assembly 5 drives the support base 3 to move laterally, a first negative pressure assembly 7 is disposed above the support base 3, and a second drive assembly 6 drives the first negative pressure assembly 7 to rise and fall. A second negative pressure component 8 is embedded and installed on the upper surface of the workbench 1, and the second negative pressure component 8 is located below the diaphragm 2; It also includes a control module 4, which is electrically connected to the first drive component 5, the second drive component 6, the first negative pressure component 7, and the second negative pressure component 8. The control module 4 controls the first drive component 5 to drive the support base 3 to move laterally toward one side of the worktable 1, so that the first negative pressure component 7 is located directly above the second negative pressure component 8. In cooperation with the second drive component 6, the first negative pressure component 7 is driven to move downward until it is in contact with the upper surface of the diaphragm 2. The control module 4 synchronously controls the first negative pressure component 7 and the second negative pressure component 8 to be turned on. The first negative pressure component 7 adsorbs the protective film 21 attached to the top of the membrane 2, and the second negative pressure component 8 adsorbs the bottom of the membrane 2. The second driving component 6 controls the first negative pressure component 7 to move upward and separate the protective film 21 on the membrane 2.

[0030] By adopting a negative pressure collaborative control mechanism, the edge of the protective film 21 is accurately and quickly separated, and the separation time is shortened to within 5 seconds, making it convenient for the operator to further peel off all the protective films 21.

[0031] After the operator places the diaphragm 2 with protective film 21 on the workbench 1, the control module 4 is activated, driving the first drive component 5 to move the support base 3 laterally and positioning the first negative pressure component 7 directly above the diaphragm 2. The second drive assembly 6 simultaneously presses down on the first negative pressure assembly 7, causing it to adhere to the upper surface of the membrane 2. Subsequently, the control module 4 precisely and synchronously activates the first negative pressure assembly 7 (adsorbing the protective film 21) and the second negative pressure assembly 8 (adsorbing the substrate of the membrane 2), and lifts the first negative pressure assembly 7 via the second drive assembly 6, achieving stress-free peeling of the edges of the protective film 21. The separation time is shortened to within 5 seconds, facilitating the operator to further remove all protective films 21.

[0032] As a further improvement, the first drive assembly 5 includes a motor 51 installed inside the worktable 1 and a gear 53 installed at one end of the drive shaft 52 of the motor 51. The support base 3 includes a rack 31 that is slidably inserted into the workbench 1. The rack 31 meshes with a gear 53 on its upper part. A base 32 is integrally provided on the outer end of the rack 31. The second drive component 6 is installed above the base 32.

[0033] By replacing the traditional guide rail structure with a gear 53 and rack 31 transmission mechanism, the motor 51 is built into the worktable 1, and the gear 53 at the end of the drive shaft 52 precisely meshes with the sliding rack 31. The outer end of the support 3 is integrated with the base 32 to support the second drive assembly 6. When manually peeling off the protective film 21, the edge of the protective film 21 is difficult to separate, resulting in a long separation time for the protective film 21 of the diaphragm 2. The gear 53 and rack 31 provide high-rigidity linear motion, eliminating sliding gaps and improving displacement control accuracy to within ±10μm, ensuring that the first negative pressure component 7 is accurately positioned directly above the diaphragm 2. The built-in motor 51 reduces external vibration interference, and the integrated base 32 strengthens structural rigidity, avoiding slight wobbling during complex curved surface fitting, while also reducing mechanical wear and extending equipment life.

[0034] During operation, after the system is started, the motor 51 drives the gear 53 to rotate, and through the meshing of the rack 31, it pushes the support seat 3 to move laterally along the inner cavity of the worktable 1, completing precise positioning within 5 seconds; The second drive component 6 then presses down on the first negative pressure component 7 to adhere to the membrane 2, and the synergistic negative pressure adsorption achieves stress-free separation of the protective membrane 21. This solves the problems of time-consuming manual operation (>120 seconds / piece) and positioning deviation, and improves the separation efficiency by more than 95%.

[0035] As a further improvement, the workbench 1 is provided with a receiving cavity, which includes a first cavity 33 for accommodating the motor 51 and a second cavity 34 for accommodating the rack 31. The first cavity 33 is cylindrical and the second cavity 34 is elongated.

[0036] Because the workbench 1 integrates a cylindrical first cavity 33 and a long strip second cavity 34, the cylindrical first cavity 33 is adapted to the motor 51 body, and a heat dissipation space is reserved to prevent the motor 51 from overheating.

[0037] The elongated second cavity 34 precisely constrains the movement trajectory of the rack 31, ensuring no lateral displacement deviation and controlling the positioning error within ±10μm. It effectively isolates workshop dust and oil mist from intrusion, extends the life of transmission components by more than 3 times, and optimizes the compactness of the equipment, avoiding exposed mechanisms from occupying operating space.

[0038] During operation, after the system starts, the motor 51 rotates smoothly within the first cavity 33, driving the gear 53 to mesh with the rack 31. The rack 31 slides linearly along the elongated guide groove of the second cavity 34, completing the precise positioning of the support 3 directly above the diaphragm 2 within 5 seconds. This process is fully automated, requiring no manual intervention, completely eliminating the bottleneck of single-piece separation exceeding 120 seconds, and improving efficiency by more than 95%. In practical applications, this structure ensures that the protective film 21 separates without residual stress, and the bonding accuracy remains stable within ±30μm.

[0039] As a further improvement, the second drive assembly 6 includes an electric push rod 61 vertically mounted on the base 32, with an auxiliary plate 62 fixedly mounted on the top of the electric push rod 61, and the first negative pressure assembly 7 disposed below the auxiliary plate 62.

[0040] The auxiliary plate 62 is made of metal, and the bottom of the auxiliary plate 62 is fixed to the top of the electric push rod 61 by welding.

[0041] By using an electric push rod 61 vertically mounted on the base 32, and a metal auxiliary plate 62 welded to the top to support the first negative pressure component 7, the problem of insufficient vertical movement accuracy and structural rigidity defects in the process of separating the protective film 21 in the process of applying film to the body of a car audio speaker is to be solved.

[0042] The electric push rod 61 provides closed-loop control with micron-level lifting accuracy (error ≤ ±5μm), eliminating the hysteresis and vibration of traditional pneumatic components and ensuring that the first negative pressure component 7 smoothly adheres to the surface of the diaphragm 2. The metal auxiliary plate 62 (such as aluminum alloy or stainless steel) has high thermal stability and anti-deformation ability, and the welding fixation eliminates mechanical gaps, avoiding displacement deviation caused by temperature drift or load when bonding complex curved surfaces, directly guaranteeing the ±50μm bonding accuracy requirement, while extending the maintenance-free cycle of the equipment by more than 2 times.

[0043] During operation, after startup, the control module 4 instructs the electric actuator 61 to drive the auxiliary plate 62 to move vertically. Within 5 seconds, the first negative pressure component 7 is pressed down onto the upper surface of the diaphragm 2 for precise adhesion. Simultaneously, negative pressure adsorption is activated to achieve stress-free separation of the protective membrane 21. Compared to the threaded screw structure, the electric actuator 61 has a 40% faster response speed, and the welded metal auxiliary plate 62 maintains rigid support during high-speed movement, significantly reducing the impact of vibration and noise on acoustic performance and providing a highly reliable process guarantee for mass production.

[0044] As a further improvement, the first negative pressure assembly 7 includes a first negative pressure adsorption nozzle 71 inserted and fixed below the auxiliary plate 62, the first negative pressure adsorption nozzle 71 being connected to an external air pump 72. The first negative pressure adsorption nozzle is provided with several independent adsorption channels 73 for precisely adsorbing the edge of the protective film 21 of the membrane 2.

[0045] By adopting the structure of insert-type first negative pressure adsorption nozzle 71 and independent adsorption channel 73, the problems of curling, tearing and residual air bubbles caused by uneven adsorption at the edge of the protective film 21 in the process of applying film to the body of car audio speaker can be directly solved.

[0046] During manual operation, the edge of the protective film 21 is prone to micro-deformation due to uneven force (deviation exceeding ±100μm), and it is easier to separate the protective film 21 from the edge. However, the edge of the protective film 21 is difficult to adsorb. Therefore, by using multiple sets of fine independent adsorption channels 73 simultaneously through partitioned negative pressure adsorption control, the micro-changes at the edge of the protective film 21 can be precisely adapted, and the adsorption accuracy can be improved to within ±10μm.

[0047] During operation, the first negative pressure suction nozzle 71 presses down onto the upper surface of the membrane 2, and the independent channel specifically activates the edge area for adsorption. Precise adsorption of the protective film 21 is completed within 5 seconds. Simultaneously, the electric push rod 61 is lifted to perform stress-free peeling, working in conjunction with the second negative pressure component 8 to maintain the stability of the membrane 2 substrate. Afterwards, the operator can directly peel off the entire protective film 21 through its separated edge. The single-piece separation time is reduced to within 5 seconds, increasing efficiency by over 95%. As a further improvement, the second negative pressure assembly 8 includes a second negative pressure suction nozzle 81 embedded in and mounted on the surface of the workbench 1. The top of the second negative pressure suction nozzle 81 is flush with the workbench 1, and the second negative pressure suction nozzle 81 is connected to an external air pump 72.

[0048] By adopting an embedded second negative pressure suction nozzle 81 structure, the top of which is precisely flush with the surface of the workbench 1 and connected to an external air pump 72, the problem of displacement, vibration and surface defects caused by unstable adsorption at the bottom of the diaphragm 2 in the process of applying film to the body of a car audio speaker is solved.

[0049] During manual operation, the membrane 2 is prone to slight displacement due to external force, which makes negative pressure adsorption difficult. The flush design eliminates the height difference on the surface of the workbench 1, ensuring that the membrane 2 is completely attached to the substrate and avoiding air gaps. The embedded structure provides a uniform negative pressure distribution, controlling the adsorption accuracy within ±10μm, directly meeting the ±50μm bonding accuracy requirement.

[0050] During operation, after the membrane 2 is placed on the workbench 1, the control module 4 instructs the air pump 72 to start the second negative pressure component 8 to establish a stable negative pressure to adsorb the substrate of the membrane 2. During the separation stage of the protective membrane 21, the first negative pressure component 7 positions and adsorbs the protective membrane 21, the second negative pressure component 8 keeps the membrane 2 absolutely stationary, and the electric push rod 61 lifts to achieve stress-free peeling.

[0051] The second negative pressure component 8 also includes a pressure sensor 82 disposed on one side of the second negative pressure suction nozzle 81, which detects the downward pressure state of the first negative pressure suction nozzle. After the first negative pressure component 7 is fully depressed, the pressure sensor 82 monitors the pressure of the first negative pressure component 7, and the control module 4 synchronously activates the first negative pressure suction nozzle and the second negative pressure suction nozzle 81 to perform suction. When the first negative pressure component 7 rises, the pressure sensor 82 detects that the pressure has been released, and for 3 seconds, the first negative pressure suction nozzle and the second negative pressure suction nozzle 81 maintain the suction state. Then, the control module 4 controls both to release pressure, and then the entire protective film 21 is manually peeled off along with the edge of the separated protective film 21.

[0052] The aforementioned electric linear actuator 61 is an existing product, and its specific structure will not be described in detail. It is also known as an electric linear actuator or linear actuator, which is an electromechanical integrated device that converts electrical energy into linear motion. It is widely used in industrial automation, medical equipment, smart homes, automobiles and solar tracking systems to achieve functions such as pushing, pulling, lifting or precise positioning.

[0053] Its core structure includes an electric motor (usually 12V / 24V DC or 220V AC), a reduction gearbox, a transmission mechanism (such as a trapezoidal screw or ball screw), a telescopic push rod, and guide and limit components.

[0054] The working principle is based on a screw drive mechanism: after the motor 51 is powered on, it rotates and outputs low speed and high torque through the reduction gearbox, driving the lead screw or nut to rotate; since the push rod is restricted from rotating by the guide structure, the rotational motion of the lead screw is converted into the linear extension and retraction motion of the push rod. The extension or retraction can be achieved by controlling the forward and reverse rotation of the motor 51. The stroke of the push rod is determined by the lead screw pitch and the speed of the motor 51. The thrust is usually between 50N and 10,000N, the speed range is about 1–100mm / s, and most models have self-locking capability, maintaining the position even after power failure.

[0055] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings.

Various modifications and variations can be made to this utility model by those skilled in the art.
