Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a fully automatic film applicator. Background Technology

[0002] Fully automatic screen protector application machines are widely used in electronics manufacturing and semiconductor production, such as for mobile phone screen protectors and IC chip protectors. The primary function of IC chip protector application is to effectively prevent scratches from hard objects during use, thus significantly extending the chip's lifespan. Simultaneously, it prevents oxidation on the chip surface, ensuring stable chip performance and long-term reliable operation. Furthermore, the chip protective film isolates the chip from environmental factors such as moisture, pollution, and ultraviolet radiation, keeping the chip surface clean and safe. This protective film is typically made of high-quality materials such as polyester, polyurethane, or polycarbonate films and is adhered tightly to the chip surface using adhesive backing, providing comprehensive protection. Workpiece screen protector application generally utilizes electrostatic adsorption to attach the film to the workpiece; however, manual application is inefficient and yields poor results. Therefore, semi-automatic screen protector application machines have emerged on the market, but their automation level is low, requiring significant manual assistance and increasing labor costs. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fully automatic film applicator and its defect identification method.

[0004] The technical solution of this utility model is as follows:

[0005] The process of product loading, film removal, film application, film patching, and unloading is integrated into one fully automated process.

[0006] This utility model provides a fully automatic film applicator, including a machine body, which is equipped with a feeding module, a film applicator, an identification module, a replenishment module, a material tray moving platform, a control system, and a discharging module.

[0007] The material tray moving platform connects the feeding module, film application component, replenishment component, and unloading module.

[0008] The feeding module includes a feeding hopper, feeding track, feeding gripper assembly, transfer feeding, and left lifting device, totaling 5 sub-modules. Each module can be controlled and operated independently.

[0009] The film application assembly includes a film transfer and application device, a right lifting device, and a feeder.

[0010] The replenishment component re-inspects the products after they have been coated, sorts all defective products into the NG area, and replenishes all good products to ensure that the tray contains only good products. This process includes two modules: transfer and unloading, and replenishment component.

[0011] Further feeder: The feeder automatically peels off the film and waits for the nozzle to pick it up. Multiple feeders can be set.

[0012] Furthermore, the feeding gripper assembly is fixed to the machine body.

[0013] The identification components include a pre-inspection component and a re-inspection component.

[0014] Further pre-inspection components include industrial cameras and distance sensors, while the re-inspection component is an industrial camera.

[0015] The invention is used as follows: a tray containing products is placed into the feeding hopper, and then transported to the transfer loading position via the feeding track and grippers. A pre-inspection component checks whether the products in the tray are suitable for film application. After inspection, the tray is transported to the film application transfer platform via the left lifting device for film application. The film application nozzle picks up the film material from the feeder, and after being guided by a positioning camera, it is applied to the product. After film application is completed, the tray is transported to the unloading transfer platform via the right lifting device and moved to the replenishment position. A re-inspection component takes pictures above the platform for re-inspection to determine if there are any defects in the film application. Defective products are picked up by the replenishment nozzle and placed in the NG area. Good products are then picked up from the good product area and placed in the empty positions of the tray. After the tray is replenished, the tray moving platform moves the tray to the unloading position. The tray is transported to the unloading hopper via the unloading grippers and unloading track. After the unloading hopper is stacked to a specified quantity, the equipment reports an error and prompts the operator to manually remove the full tray.

[0016] Defect identification methods:

[0017] Step 1: Pre-application inspection

[0018] The system uses distance sensors and industrial cameras for detection; if any malfunction is detected, an alarm will be triggered for manual intervention.

[0019] Step 2: Post-application follow-up inspection

[0020] The large model is called via API to automatically identify defects.

[0021] The beneficial effects achieved by this utility model are as follows:

[0022] This utility model integrates product loading, film peeling, film application, film patching, and unloading into a fully automated process. It features fast application speed, high precision, and efficient and accurate completion of product film application and handling tasks. It includes pre-application inspection to check for foreign objects, dust, scratches, etc., and post-application re-inspection to check application accuracy, bubbles, foreign objects, etc. Through pre- and re-inspections, the product off-line rate is 100%.

[0038] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0039] The product in this embodiment is an IC chip. The device for placing the IC chip is called a tray or a material tray. The film is divided into sheets.

[0040] Structural Introduction:

[0041] like Figures 1-9 As shown, this utility model provides a fully automatic film applicator, including a machine body 1, a feeding module 2, a film applicator 3, an identification module 4, a replenishment module 5, a material tray moving platform 6, a control system 7, and a discharging module 8.

[0042] The feeding module 2 is on one side of the machine body 1, the unloading module 8 is on the other side of the machine body 1, the film application component 3 can apply the film to the product, and the material tray moving platform 6 connects the feeding module 2, the film application component 3, the replenishing component 5, and the unloading module 8.

[0043] The feeding module 2 includes a feeding bin 205, a feeding track 201, a feeding gripper assembly 202, a transfer feeding 203, and a left lifting device 204, totaling 5 sub-modules. Each module can be controlled and operated independently.

[0044] Feed hopper 205 is used to hold multiple material trays.

[0045] The feeding track 201 automatically separates the trays of products that have been loaded, and feeds the trays to the position to be picked up, waiting for the feeding gripper assembly 202 to pick them up.

[0046] The left lifting device 204 can lift or lower the material tray to the material tray moving platform 6. The left lifting device 204 is equipped with a lifting plate 2041.

[0047] The feeding gripper assembly 202 module grabs the material tray that is already in place on the feeding track 201 and transports it to the transfer feeding position 203. The feeding gripper assembly 202 includes a material tray gripper 2021 and a gripper moving device 2022. The gripper moving device 2022 is fixed to the machine body 1 by a fixing block. The gripper moving device 2022 drives the material tray gripper 2021 to move back and forth. The material tray gripper 2021 is equipped with a cylinder or motor, which can move up and down.

[0048] The transfer and loading unit 203 is located above the material tray moving platform 6. The product is pre-inspected and positioned at this location. The camera and distance sensor move above the material tray under the control of the control system 7 to take pictures, automatically identify and detect the presence of foreign objects, dust, scratches, etc. on the product, and locate the position of each IC chip.

[0049] After the pre-inspection is completed, the material tray moving platform 6 moves the material tray to the left lifting device 204. The left lifting device 204 lifts the material tray to a certain height to prepare for film application.

[0050] The film application assembly 3 includes a film transfer and application device 301, a right lifting device 302, and a feeder 303.

[0051] The left lifting device 204 and the right lifting device 302 have the same structure, see reference. Figure 6 The locations are different.

[0052] The film transfer and film application device 301 applies film to the pre-inspected and OK products in the tray. After the film application is completed, the left lifting device 204 lowers and places the tray on the tray moving platform 6. The tray moving platform 6 moves the tray to the transfer and unloading position, while the left lifting device 204 lifts up a new tray of IC chips that need to be film applied.

[0053] The film transfer device 301 includes a film transfer device 3011 and a film application device 3012. The film application device 3012 includes a suction nozzle 30121, a rotating shaft 30122, and a vacuum generator 30123.

[0054] The vacuum generator 30123 can adsorb or release the film in a vacuum state. The suction nozzle 30121 is fixed on the rotating shaft 30122. The rotating shaft 30122 can be finely adjusted in angle, and the suction nozzle 30121 is adjusted at the same time to align with the IC chip, ensuring the accuracy of each application.

[0055] The right lifting device 302 rises to lift the material tray on the transfer film applicator 301 away from the transfer film applicator 301, waiting for the material to be transferred into place.

[0056] Feeder 303: The feeder automatically peels off the film and waits for the suction nozzle 30121 to pick it up. In this embodiment, there are two sets of feeders 303.

[0057] The replenishment component 5 is used to re-inspect the products after film application, sort all defective products to the NG area 502, replenish good products to ensure that the material tray is full of good products, transfer and unload the materials, and re-inspect at this station to check the application accuracy, air bubbles, foreign objects, etc.

[0058] The right lifting device 302 descends, and the tray containing the IC chip is transferred to the transfer and unloading station. The transfer and unloading tray moves to the unloading tray position, waiting for the unloading gripper to pick it up.

[0059] The feeding assembly 5 includes a suction assembly 501, an NG zone 502, a good zone 503, and a lower camera 504.

[0060] The suction component 501 re-inspects the products after they have been coated, sorts all the defective products into the NG area 502, replenishes them from the good product area 503 until the material tray is full, and then moves them to the unloading position to wait for the unloading gripper to pick them up.

[0061] The structure and operating principle of the material suction assembly 501 are similar to those of the transfer and film application device 301, and it is used to pick up and place IC chips. The material suction assembly 501 is equipped with a material suction nozzle 5011.

[0062] If the re-inspection component 403 finds a defective IC chip in the product after film application, the right lifting device 302 rises and lifts the tray to the designated position. The suction component 501 picks up the defective IC chip and places it in the defective area. Then, the IC chip is taken from the good product area 503, and at the lower camera 504, the angle is adjusted and it is placed in the original position of the defective product to ensure that the entire tray is filled with good products. Then, the right lifting device 302 descends and places the tray on the tray moving platform 6. The tray moving platform 6 moves the tray to the transfer and unloading position.

[0063] If the material feeding component 501 fails to pick up an IC chip, the re-inspection component 403 will take pictures of the defective area and the good area 503 and send them to the control system 7. The control system 7 will automatically determine whether there is a shortage of material. If there is a shortage of material, an alarm will be set to prompt manual handling; otherwise, the IC chip will be picked up again.

[0064] The identification component 4 includes a pre-inspection component 401, a positioning camera 402, and a re-inspection component 403.

[0065] The positioning camera 402 is located on one side of the film application device 3012, which can realize the positioning of one IC chip while applying film to another IC chip.

[0066] Furthermore, the pre-inspection component 401 includes a pre-inspection camera and a pre-inspection distance sensor, and the re-inspection component 403 is equipped with an AI smart camera.

[0067] The unloading module 8 includes an unloading track 801, an unloading gripper assembly 802, and an unloading bin 803, totaling three sub-modules. Each sub-module can be controlled and operated independently.

[0068] The feeding track 801, in conjunction with the feeding bin 803, automatically stacks multiple material trays together.

[0069] The method of using this utility model is as follows: A tray containing products is placed into the feeding hopper 205, and then transported to the transfer loading position 203 via the feeding track and grippers. The pre-inspection component 401 detects whether the products in the tray are suitable for film application. After detection, the tray is transported to the film application transfer platform 3011 via the left lifting device 204 for film application. The film application nozzle 30121 picks up the film material from the feeder 303, guides it through the positioning camera 402, and applies it to the product. After the film application is completed, the tray is moved back to the right lifting device 3012. 2. The material is moved to the unloading and transfer platform and then to the replenishment position. The re-inspection component 403 is placed above the platform to take pictures and re-inspect to determine if there are any defects in the film. Defective products are picked up by the replenishment nozzle 30121 and placed in the NG area 502. Good products are then picked up from the good product area 503 and placed in the empty position of the material tray. After the material tray is full, the material tray moving platform 6 moves the material tray to the unloading position. The material tray is transported to the unloading bin 803 by the unloading claw and the unloading track 801. After the material tray 803 is stacked to the specified quantity, the equipment reports an error and prompts the user to manually remove the full material tray.

[0070] Because of the short equipment cycle, defect detection is crucial.

[0071] The defect identification method consists of two steps.

[0072] Step 1: Pre-application inspection

[0073] The pre-inspection distance sensor 4012 and the pre-inspection camera 4011 are used to detect the presence of foreign objects, dust, scratches, etc. on the product.

[0074] Distance sensors acquire distance data of IC chips throughout the entire tray, and various algorithms detect defects such as dust, scratches, and distance discrepancies.

[0075] Reference Publication No.: CN 118067024A A technical document concerning a product warpage detection device and its detection algorithm.

[0076] The camera 4011 takes pictures during pre-inspection and transmits them to the control system 7. The control system 7 automatically matches the IC chip to determine whether it is good or bad based on the parameters set for foreign objects, dust, scratches, etc.

[0077] Step 2: Post-application follow-up inspection

[0078] The camera in the re-inspection component 403 is equipped with an AI intelligent camera, which can call a large model via API to control system 7 to automatically determine defects.

[0079] This embodiment utilizes the SC6000 series AI smart camera, developed on a high-performance embedded platform, possessing powerful AI capabilities. It has built-in VM algorithm software, allowing free use of over 140 algorithm functions. While possessing powerful processing capabilities, it also maintains high ease of use and strong flexibility, making it widely applicable in complex application scenarios such as positioning, measurement, recognition, and detection across various industries, making it the ideal choice for single-camera vision systems. Numerous images of good and defective products need to be pre-trained on a large model. The trained model then uses artificial intelligence technology to automatically identify defects.

[0080] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
