Description

Technical Field

[0001] This utility model relates to the technical field of membrane processing platforms, and in particular to a membrane adsorption and conveying fixture. Background Technology

[0002] In precision manufacturing fields such as electronic devices, optical thin films, and flexible printed circuit boards (FPCs), films (such as flexible circuit board substrates, optical protective films, and display panel films) are core raw materials. Their processing requires extremely high precision in conveying, surface flatness, and positioning accuracy. Films are typically thin (e.g., a few micrometers to hundreds of micrometers), soft (e.g., PET, PI, PVC, and other polymers), and easily deformed by external forces. Therefore, on the production line, specialized tooling is required to achieve stable adsorption, precise conveying, and surface flattening to avoid problems such as wrinkles, misalignment, or scratches, and to ensure the quality of subsequent processing (such as drilling, bonding, and exposure).

[0003] Currently, traditional membrane conveying methods mostly use ordinary conveyor belts or roller conveyor lines. However, these methods have significant drawbacks: Firstly, the friction of the conveyor belt can easily cause the membrane to not adhere tightly to the conveying surface. Especially during high-speed conveying or reversal, the membrane is prone to wrinkles or shifts due to uneven tension, affecting positioning accuracy. Secondly, ordinary conveyors cannot provide vertical adsorption force. For ultra-thin or smooth-surfaced membranes (such as PET films with a thickness of less than 50μm), reliable fixation is difficult to achieve, and the "ribbon drifting" phenomenon is likely to occur, leading to conveying failure or processing misalignment. Utility Model Content

[0007] This utility model of membrane adsorption and conveying fixture, through the integrated design of adsorption and flattening functions, adaptive pressure control and stable limiting structure, realizes the coordinated operation of "stable adsorption-precise conveying-real-time flattening" in the membrane conveying process, which significantly improves the efficiency and quality of membrane processing.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the appended spirit and connotation.

[0019] The membrane adsorption and conveying fixture of this utility model embodiment will be described below with reference to the accompanying drawings.

[0020] like Figure 1-2 As shown, the membrane adsorption and conveying fixture of this utility model embodiment includes a fixed frame 10, a conveyor belt 20 rotatably mounted on the fixed frame 10, and an adsorption component 30 mounted on the conveyor belt 20.

[0021] It should be noted that the fixing frame 10 described in this embodiment is installed on the film processing equipment. A stepper motor is provided on the fixing frame 10. The stepper motor is connected to the power supply through a control switch and is operated. The stepper motor is connected to the rotating shaft through a reducer. The rotating shaft drives the conveyor belt 20 to rotate.

[0022] The adsorption assembly 30 includes a fixed housing 301, a driving component 302, a base plate 303, and an adsorption component 304.

[0023] The fixed housing 301 is mounted on the conveyor belt 20, the driving component 302 is mounted on the fixed housing 301, the base plate 303 is mounted on the output end of the driving component 302, the adsorption component 304 is in multiple sets, and the multiple sets of adsorption components 304 are respectively mounted on the base plate 303. A flat pressure component 40 is mounted on one side of the base plate 303.

[0024] It should be noted that in this embodiment, the fixed housing 301 is detachably installed on the conveyor belt 20 and fixed in a limiting manner. The limiting and fixing is achieved by pressing a threaded connection control plate onto the conveyor belt 20 for fixation.

[0025] Furthermore, the adsorption component 304 includes a conduit and a suction nozzle. The conduit is mounted on the base plate 303, and the driving component 302 is a hydraulic cylinder. When the driving component 302 is running, it drives the base plate 303 to move up and down.

[0026] In one embodiment of this utility model, such as Figure 2 As shown, the flat pressing assembly 40 includes a fixed side plate 401, a pressing mechanism 402, and a limiting mechanism 403.

[0027] The fixed side plate 401 is disposed on one side of the base plate 303, the film pressing mechanism 402 is disposed on the fixed side plate 401, and the limiting mechanism 403 is movably disposed on the fixed side plate 401, and the limiting mechanism 403 is connected to the film pressing mechanism 402.

[0028] It should be noted that the fixed side plate 401 is installed on one side of the base plate 303 and on the other side of the moving end of the adsorption membrane, driving the membrane to move. During the adsorption process, the adsorption membrane is adsorbed by the adsorption component 304 and driven to the processing point.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, the film pressing mechanism 402 includes a support plate 4021, a reset component 4022, and a pressure roller 4023.

[0030] The support plate 4021 is mounted on the film pressing mechanism 402, the two ends of the reset component 4022 are respectively connected to the fixed side plate 401 and the support plate 4021, and the pressure roller 4023 is rotatably mounted on the support plate 4021.

[0031] It should be noted that the reset component 4022 is a reset spring. The two ends of the reset component 4022 are respectively connected to the fixed side plate 401 and the support plate 4021. When the reset component 4022 pushes the support plate 4021 down, the pressure roller 4023 moves down and abuts against the surface of the diaphragm.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, the limiting mechanism 403 includes a movable plate 4031 and a positioning block 4032.

[0033] The movable plate 4031 is movably mounted on the fixed side plate 401, and one end of the movable plate 4031 is connected to the support plate 4021. The positioning block 4032 is mounted on the movable plate 4031.

[0034] It should be noted that the movable plate 4031 moves within the fixed side plate 401, and the positioning block 4032 presses against the fixed side plate 401 when it moves, thus limiting the position of the support plate 4021.

[0035] In one embodiment of this utility model, such as Figure 2 As shown, the bottom wall of the pressure roller 4023 is located below the bottom wall of the adsorption component 304, and the pressure roller 4023 is a smooth alloy roller.

[0036] It should be noted that the surface of the pressure roller 4023 is designed to be a smooth plane, which only presses the surface of the diaphragm, flattens the diaphragm, and prevents the diaphragm from moving during the rolling process.

[0037] Specifically, the steps for using the membrane adsorption and conveying fixture are as follows:

[0038] First, place the diaphragm on the conveyor belt 20, start the stepper motor, and the stepper motor drives the rotating shaft to rotate through the reducer, thereby driving the conveyor belt 20 to rotate.

[0039] Next, the driving component 302, i.e., the hydraulic cylinder, starts to work, driving the base plate 303 to descend, so that the suction nozzle of the adsorption component 304 comes into contact with the diaphragm, and the diaphragm is firmly adsorbed onto the suction nozzle through negative pressure adsorption.

[0040] As the conveyor belt 20 continues to rotate, the adsorption assembly 30, which adsorbs the film, moves with the conveyor belt 20 to the film processing station. When the film is transported to the processing point, the drive component 302 drives the base plate 303 to rise, and the adsorption component 304 releases the film, which falls onto the processing equipment. At this time, the pressure roller 4023 of the film pressing mechanism 402, pushed by the reset component 4022 (i.e., the reset spring), abuts against the surface of the film to flatten it. Simultaneously, the movable plate 4031 of the limiting mechanism 403 moves on the fixed side plate 401, and the positioning block 4032 presses against the fixed side plate 401, limiting the support plate 4021 and the pressure roller 4023 to ensure that the pressure roller 4023 can stably flatten the film.

[0041] In summary, the membrane adsorption and conveying fixture of this utility model embodiment can stably and efficiently complete the conveying and flattening of membranes, thereby improving the efficiency and quality of membrane processing.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
