Description

Technical Field

[0001] This utility model relates to the field of electronic product processing technology, and in particular to an automatic loading and unloading film application device. Background Technology

[0002] Automatic film applicators are automated film application devices used for electronic products. They achieve high-precision application of protective films through robotic arms and a precision control system, ensuring no bubbles or wrinkles. Their core functions include surface cleaning, position calibration, and film lamination, making them suitable for applying protective films to precision components such as mobile phones, computers, and wafers.

[0003] This equipment is typically equipped with a robotic arm and vacuum suction clamps for automated loading and unloading. However, in high-cleanliness environments, the film-coating material may release trace particles, such as cutting debris and residual silicone oil from the release film, which can easily cause blockages in the vacuum pipeline or failure of critical components such as solenoid valves and vacuum generators, affecting the stability of the equipment. Utility Model Content

[0004] Therefore, it is necessary to provide an automatic loading and unloading film applicator to address the problem that the loading and unloading structure using vacuum adsorption clamps is prone to blockage of the vacuum system or failure of key components due to impurities.

[0005] An automatic film applicator includes: an automatic film applicator, two vacuum suction robotic arms, two electric conveyor belts, and two anti-clogging mechanisms. The two vacuum suction robotic arms are respectively located on the feeding side and the discharging side of the automatic film applicator, and the two electric conveyor belts are respectively located on the side of the two vacuum suction robotic arms facing away from the automatic film applicator.

[0006] In one embodiment, the anti-clogging mechanism includes two tri-pronged pipes, both of which are embedded in the gas pipeline of the vacuum adsorption robotic arm. One end of each tri-pronged pipe is fixedly connected to and communicates with a first one-way valve and a second one-way valve, respectively. The one-way blocking direction of the first one-way valve and the opposite one-way valve at the same height is the same, and the one-way blocking direction of the first one-way valve and the opposite one-way valve at the same height is opposite. A detachable filter assembly is fixedly connected and communicates with the first one-way valve and the opposite one-way valve.

[0007] In one embodiment, the detachable filter assembly includes a bent pipe fixedly connected to and communicating with the outlet end of a first one-way valve. A mounting cylinder is fixedly connected to the surface of the bent pipe, and a filter cylinder is embedded inside the mounting cylinder. A discharge pipe is fixedly connected to and communicating with the inlet end of a second one-way valve on the surface of the mounting cylinder. The opposite ends of the bent pipe and the discharge pipe are respectively located on the inner and outer sides of the filter cylinder.

[0008] In one embodiment, the side end of the mounting cylinder is provided with a threaded hole, and a sealing cap that is fixedly connected to the filter cylinder is threaded to the inner side of the threaded hole.

[0009] In one embodiment, the inner diameter of the filter cartridge is larger than the diameter of the bend, and one end of the bend extends through the inner side of the filter cartridge.

[0010] In one embodiment, the sealing cap has a threaded groove at one end inside the mounting cylinder, and the surface of the filter cylinder has an external thread that is threadedly connected to the threaded groove.

[0011] In one embodiment, the other end of the sealing cap has a beveled hexagonal corner.

[0012] In one embodiment, a sealing ring is embedded in the surface of the sealing cap, and the sealing ring fits against the mounting cylinder.

[0013] In one embodiment, the inner diameter of the sealing ring is larger than the inner diameter of the mounting cylinder, and the diameter of the sealing ring is smaller than the diameter of the mounting cylinder and the sealing cap.

[0014] Beneficial effects

[0015] 1. The above-mentioned automatic loading and unloading film-applying device effectively prevents vacuum system blockage through an anti-clogging mechanism, ensuring stable equipment operation. The anti-clogging mechanism adopts a bidirectional airflow filtration design. When the airflow passes through the three-way pipe, regardless of the flow direction, it must be guided to the detachable filter assembly through the first and second one-way valves. The multi-layer filter media of the filter cartridge intercepts debris, dust, and oil. This design prevents impurities from entering the vacuum generator or porous suction cup of the vacuum adsorption robotic arm, significantly reducing the risk of failure of key components and improving the reliability of loading and unloading operations.

[0016] 2. This film applicator enables rapid maintenance and reduces downtime through its modularly designed detachable filter components. The filter cartridge is fixed inside the mounting cylinder by the engagement of the threaded groove and the external thread. The hexagonal design of the sealing cap facilitates manual disassembly. When replacing the filter cartridge, simply unscrew the sealing cap to remove it. The operation is simple and efficient. This design ensures that the regular cleaning or replacement of the filter components does not affect the production cycle and maintains the efficient and continuous operation of the automatic film applicator.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is combined Figure 1 - Figure 5 This invention describes an automatic loading and unloading film-applying device.

[0027] In one embodiment, an automatic film applicator includes: an automatic film applicator 100, two vacuum suction robotic arms 200, two electric conveyor belts 300, and two anti-clogging mechanisms 400. The two vacuum suction robotic arms 200 are respectively disposed on the feeding side and the discharging side of the automatic film applicator 100, and the two electric conveyor belts 300 are respectively disposed on the side of the two vacuum suction robotic arms 200 facing away from the automatic film applicator 100.

[0028] The automatic film applicator 100 is the core film applicator, which performs precise film application on electronic products. Its core structure includes:

[0029] Film applicator: Integrated with a high-precision pressure sensor to ensure that the film is applied without bubbles or wrinkles.

[0030] Positioning module: Equipped with a visual positioning system (such as a CCD camera) or mechanical positioning fixture to ensure alignment between the product and the film.

[0031] Drive system: The lifting and lateral movement of the film applicator head is controlled by a servo motor or pneumatic device.

[0032] Membrane roll mechanism: includes unwinding shaft, waste film collection shaft and tension control components, to realize automatic membrane conveying and waste membrane recycling.

[0033] The vacuum adsorption robotic arm 200 is a structure that completes the gripping, transfer, and placement of electronic products on the feeding and discharging sides of the automatic film applicator 100. It is a SCHUNK GSW-V20-SND125 model vacuum robotic arm, and its core structure includes:

[0034] Adsorption end: Equipped with a porous silicone suction cup or a customized fixture to adapt to different product shapes, and achieves stable adsorption through a vacuum generator.

[0035] Sports institutions:

[0036] Multi-axis robotic arm: It adopts a three-axis (XYZ) linear module or a six-axis collaborative robotic arm, driven by servo motors.

[0037] Rotation module (optional): A rotary cylinder is added at the end for adjusting the product angle.

[0038] Sensors: Integrated pressure sensor (to detect adsorption state) and photoelectric sensor (for product positioning).

[0039] The vacuum generating system, specifically, includes the following structure:

[0040] Vacuum generator: The air pipe is connected to the multi-hole suction cup of the vacuum clamp by controlling the air pipe through the solenoid valve. The opposite ends of the air pipe and the multi-hole suction cup of the vacuum clamp are fixedly connected and connected to the opposite ends of the two three-way pipes 410. It should be noted that the airflow must first pass through the first one-way valve 420 and then through the opposite second one-way valve 430.

[0041] Air supply line: Connects to the factory's compressed air network, and supplies air to the vacuum generator after passing through a filter and pressure reducing valve.

[0042] Control and detection module: PLC controller, and requires a vacuum pressure sensor to monitor the adsorption force in real time and trigger an alarm if adsorption fails.

[0043] The electric conveyor belt 300 transports products to be laminated on the infeed side and carries laminated products on the outfeed side. It is the AZM-HT1 model of the Qintaisheng brand fully automatic laminating equipment, whose core structure includes:

[0044] Conveyor belt body: anti-static belt or synchronous belt, width adapted to the size of electronic products.

[0045] Drive unit: A geared motor works in conjunction with a frequency converter to achieve speed control.

[0046] Guidance organization:

[0047] Adjustable guardrail: Aluminum alloy guide rail to prevent product deviation.

[0048] Detection module: photoelectric sensor or fiber optic sensor, to detect the product arrival signal.

[0049] The overall operation of the film-applying device is as follows: The product to be applied is placed on the electric conveyor belt 300 on the feeding side. After the electric conveyor belt 300 transports the product to the designated position, the vacuum suction robot arm 200 grabs the product through a vacuum suction cup. After the visual positioning system calibrates the position, it is transferred to the automatic film applicator 100. In the automatic film applicator 100, the film applicator head presses down with constant pressure, simultaneously releasing the protective film and recycling waste materials to ensure no bubbles or wrinkles. After the film is applied, the vacuum suction robot arm 200 on the discharge side grabs the finished product and transfers it to the electric conveyor belt 300 on the discharge side for transport to the next process. After a single operation is completed, all mechanisms reset and stand by. This system has a short cycle time, high yield rate, and convenient changeover. It is suitable for applying films to various electronic products and supports intelligent production management.

[0050] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the anti-clogging mechanism 400 includes two three-way pipes 410. Both three-way pipes 410 are embedded in the gas pipeline of the vacuum adsorption robotic arm 200. One end of each three-way pipe 410 is fixedly connected to and communicates with a first one-way valve 420 and a second one-way valve 430. The one-way blocking direction of the first one-way valve 420 and the opposite one-way valve 430 at the same height is opposite. The first one-way valve 420 and the opposite one-way valve 430 are fixedly connected and communicate with a detachable filter assembly 440.

[0051] like Figure 3 , Figure 4 and Figure 5As shown, the detachable filter assembly 440 includes a bent pipe 441 fixedly connected to and communicating with the air outlet of the first one-way valve 420. A mounting cylinder 442 is fixedly connected to the surface of the bent pipe 441. A filter cylinder 443 is embedded inside the mounting cylinder 442. A discharge pipe 444 is fixedly connected to and communicating with the air inlet of the second one-way valve 430. The opposite ends of the bent pipe 441 and the discharge pipe 444 are respectively located on the inner and outer sides of the filter cylinder 443.

[0052] The filter cartridge 443 is equipped with various cylindrical filter media arranged from the inside out, as detailed below:

[0053] Stainless steel mesh (outer layer): intercepts large particles and mechanical impurities.

[0054] Fiber layer (middle layer): Adsorbs fine dust and particulate matter.

[0055] Oleophilic / hydrophobic layer (inner layer): Polypropylene (PP) or Teflon coating can separate oil.

[0056] The mounting cylinder 442 has a threaded hole 445 on its side end, and a sealing cap 446 that is fixedly connected to the filter cylinder 443 is threaded to the inside of the threaded hole 445. The inner diameter of the filter cylinder 443 is larger than the diameter of the bent tube 441, and one end of the bent tube 441 extends through to the inside of the filter cylinder 443. The sealing cap 446 has a threaded groove 447 on one end inside the mounting cylinder 442, and an external thread 448 that is threaded to the threaded groove 447 is on the surface of the filter cylinder 443. The other end of the sealing cap 446 has a beveled hexagonal edge. A sealing ring 449 is embedded in the surface of the sealing cap 446 and fits against the mounting cylinder 442. The inner diameter of the sealing ring 449 is larger than the inner diameter of the mounting cylinder 442, and the diameter of the sealing ring 449 is smaller than the diameters of the mounting cylinder 442 and the sealing cap 446.

[0057] In this embodiment, when the user needs to replace the filter cartridge 443, the user only needs to unscrew the sealing cap 446 from the threaded hole 445, and then remove the sealing cap 446 together with the filter cartridge 443. Finally, the filter cartridge 443 is screwed out of the threaded groove 447 through the external thread 448. At this time, the filter cartridge 443 is completely removed, and the user can quickly complete the installation work by reversing the above operations on the new filter cartridge 443.

[0058] Working Principle: During the negative pressure adsorption or pressure restoration operation of the porous suction cup by the vacuum generator through the pipeline, the airflow follows the connected three-way pipe 410 through the first one-way valve 420 in the unlocked state, and then enters the mounting cylinder 442 through the bend pipe 441. The filter cylinder 443 filters out impurities such as debris, dust, and oil in the airflow. Subsequently, the clean airflow enters another three-way pipe 410 through the discharge pipe 444 and the connected second one-way valve 430. The other three-way pipe 410 guides the airflow to the vacuum generator or the porous suction cup accordingly. This design of bidirectional airflow filtration ensures that the airflow is filtered and purified before entering the corresponding connected structure, regardless of the flow direction. This effectively reduces the risk of blockage and failure of the vacuum generator or the porous suction cup, thereby improving the effectiveness and reliability of vacuum adsorption furniture loading and unloading operations.

[0059] It should be noted that the automatic film applicator 100, vacuum adsorption robotic arm 200, electric conveyor belt 300, first one-way valve 420, second one-way valve 430, and filter cartridge 443 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the automatic film applicator 100, vacuum adsorption robotic arm 200, and electric conveyor belt 300 can be powered by built-in power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0060] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
