Technical Field

[0001] This utility model relates to an electronic product processing equipment, specifically a fully automatic electronic product film application device. Background Technology

[0002] In the manufacturing process of some sheet-like electronic products, such as mobile phones and tablets, it is necessary to apply a protective film to the product surface to prevent scratches and contamination. Traditional film application mainly relies on manual operation, which suffers from low efficiency, poor consistency, and easy introduction of contamination. While existing semi-automated equipment can achieve some functions, it mostly adopts a separate workstation design, resulting in multiple positioning and transfer of products and significant accumulated errors. In addition, after the film is applied, the product needs to be placed upside down in the packaging box. Conventional automated production lines cannot achieve the process of transferring products without compromising the quality of the film application, which affects the large-scale production of products. Therefore, a fully automated film application device is needed to build a reliable automated system. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a fully automatic electronic product film application device, including a transport conveyor line, on which a carrier for transporting products is arranged, and along the transport direction of the transport conveyor line, the following are arranged sequentially:

[0004] Product dust removal mechanism, used to clean product surfaces;

[0005] A film-applying robot is used to pick up and apply film to the surface of a product.

[0006] Electrostatic dust removal system is used to eliminate static electricity and residual dust on the product surface;

[0007] The flipping mechanism has a transfer frame on its side, which is used to transfer the filmed product to the transfer frame and flip it.

[0008] The flipping mechanism includes a rotary drive and a clamping assembly connected to the output end of the rotary drive.

[0009] Furthermore, the clamping assembly includes a clamping cylinder, two sets of clamping plates that move relative to each other driven by the clamping cylinder, a lower support plate provided at the lower end between the clamping plates, and an L-shaped upper support plate provided on the inner side of the clamping plates.

[0010] Furthermore, the transmission flow line is at least one set of directional linear motors, and the carrier is connected to the moving part of the linear motor.

[0011] Furthermore, the product dust removal mechanism includes a first support and at least one set of rubber rollers, pressure rollers and drive roller assemblies disposed thereon; the pressure roller is disposed above the rubber roller, and a cleaning cloth driven and guided by the drive roller assembly is disposed between the rubber roller and the pressure roller; the rubber roller is located above the conveyor flow line and contacts the product surface when the product moves.

[0012] Furthermore, the product dust removal mechanism is connected to the first longitudinal transfer module, which is arranged in a direction perpendicular to the transport flow line.

[0013] Furthermore, the electrostatic dust removal mechanism is an ion wind cleaning mechanism provided for each carrier, and the ion wind cleaning mechanism is fixed above the transmission flow line by a second bracket.

[0014] Furthermore, the film-applying robot is a four-axis articulated robot, and its output end is equipped with a film-applying component.

[0015] Furthermore, the film-applying assembly includes: a third bracket fixed to the robotic arm, a fourth bracket slidably connected to the third bracket, and a buffer spring between the third bracket and the fourth bracket; the fourth bracket is provided with an adsorption plate for adsorbing the film, and one end of the adsorption plate is provided with a rolling roller for rolling the film.

[0018] This invention provides a fully automated electronic product film application device, including a transport conveyor, a product dust removal mechanism, an electrostatic dust removal mechanism, a film application robot, and a flipping mechanism. Products are transported to each module via carriers. The product dust removal mechanism uses a rubber roller and a cleaning cloth to remove larger particles and impurities from the product surface. The film application robot, driven by a four-axis articulated robot, picks up the film using an adsorption plate and applies it flexibly with rollers. The electrostatic dust removal mechanism uses ion air to neutralize static electricity and residual dust on the product surface.

[0032] 8 unloading robot Detailed Implementation

[0033] like Figure 1The illustrated fully automatic electronic product screen protector applicator is suitable for screen protector application processes on board-type electronic products such as mobile phones and tablets. The applicator includes a conveyor line 1, along which, in sequence, are a product dust removal mechanism 2, an electrostatic dust removal mechanism 3, an applicator robot 4, a flipping mechanism 5, and a unloading robot 8. A transfer station is located on the side of the flipping mechanism 5. As the product moves along the conveyor line 1, before applicating, the product dust removal mechanism 2 removes dust or debris from the product surface to keep it clean. After dust removal, the applicator robot 4 picks up the film and applies it to the product surface. The product continues to move along the conveyor line 1, where the electrostatic dust removal mechanism 3 eliminates static electricity and removes dust. Finally, the flipping mechanism 5 moves the product to the transfer station and flips it, and finally, the unloading robot 8 moves it to the next process.

[0034] The transport line 1 is used for the directional transfer of products to be coated with film. In this embodiment, the transport line 1 consists of two parallel linear motors 11. A carrier 12 is connected to the moving part of each linear motor 11, and the product is placed above the carrier 12. Each linear motor 11 transports one product, providing forward propulsion, and the product passes through each workstation for processing in sequence.

[0035] Among them, such as Figure 2 As shown, the product dust removal mechanism 2 includes a first support 21, at least one set of rubber rollers 23 rotatably mounted on the first support 21, a pressure roller 24, and a transmission roller assembly. The rubber rollers 23 are located above the conveyor flow line 1 and are made of materials such as rubber, possessing certain adsorption and deformation capabilities. The height of the rubber rollers 23 is approximately equal to the upper surface of the product. When the product passes through the product dust removal station, it comes into contact with the lower surface of the rubber rollers 23. Due to the material properties of the rubber rollers 23, dust and debris on the product surface are captured, thus cleaning the product surface.

[0036] A pressure roller 24 is positioned above a rubber roller 23, arranged in pair with it. A cleaning cloth 25, made of materials such as microfiber, is placed between the rubber roller 23 and the pressure roller 24. Driven and guided by a transmission roller assembly, the cleaning cloth 25 passes between the rubber roller 23 and the pressure roller 24. During contact with the surface of the rubber roller 23, it removes dust and debris adsorbed on the surface, keeping the surface of the rubber roller 23 clean and reusable, preventing unnecessary contamination from repeated contact with the product surface. The transmission roller assembly includes a drive roller 26 and a driven roller 27. The cleaning cloth 25 is sequentially wound around each drive roller 26 and driven roller 27. The drive roller 26 is driven to rotate by a servo motor 28, providing the moving power for the cleaning cloth 25. The driven roller 27 guides the movement path of the cleaning cloth 25, ensuring sufficient friction to the rubber roller 23 and guaranteeing a cleaning effect.

[0037] In this embodiment, two linear motors 11 are provided. In order to enable the product dust removal mechanism 2 to process the products on the two linear motors 11, the first bracket 21 is connected to the transmission end of a first longitudinal movement module 22. The first longitudinal movement module 22 is set along a direction perpendicular to the transmission flow line 1, driving the product dust removal mechanism 2 to move above the two linear motors 11, so as to improve work efficiency.

[0038] like Figure 3 As shown, the electrostatic dust removal mechanism 3 includes two sets of ion air cleaning mechanisms 31, one set for each carrier 12. The ion air cleaning mechanism 31 adopts a fixed structure and is connected above the transmission flow line 1 through the second bracket 32. The principle of ion air cleaning is to ionize the air through a high-voltage electric field. These ion airflows are blown toward the product surface, which can neutralize the static electricity on the product surface and make the surface dust lose its adsorption force, and then be carried away by the airflow.

[0039] This invention features two cleaning stations before and after film application. The first station removes larger particles and debris from the product surface, while the second station neutralizes residual static electricity and removes fine dust. This ensures the cleanliness of the product surface and reduces the formation of air bubbles during film application, thereby guaranteeing the quality of the film application.

[0040] After the product is coated, it is in a face-up position. However, when the product is stored or enters the next process, it needs to be face-down. Therefore, at the end of the conveyor line 1, there is also a... Figure 5 and Figure 6 The flipping mechanism 5 shown is installed at the flipping station to transfer the film-coated product from the transport flow line 1 to a transfer station on one side and flip it. A transfer frame 6 is installed at the transfer station to temporarily store the product. The flipping mechanism 5 includes a product-transferring clamping assembly 54, which is connected to the output end of a rotary drive 53 to drive the product to flip. The flipping mechanism 5 is connected to a lifting module 51 and a second longitudinal movement module 52 to drive the product to move longitudinally and vertically, respectively. The rotary drive 53 is connected to the lifting module 51, and the lifting module 51 is connected to the second longitudinal movement module 52. The second longitudinal movement module 52 can move the product between the transfer frame 6 and the transport flow line 1. Corresponding to the two linear motors 11 in this embodiment, the second longitudinal movement module 52 can move above the two linear motors 11 to transfer the product according to the different product positions, and the clamping assembly 54 transfers the product between the two positions. The second longitudinal transfer module 52 is connected to a lifting module 51, which can drive the product to move vertically, placing or removing the product from the conveyor line 1 or the transfer frame 6. The lifting module 51, the second longitudinal transfer module 52, and the rotary drive component 53 are all controlled by the central system to automatically complete the product transfer process.

[0041] like Figure 4 As shown, the clamping assembly 54 includes a clamping cylinder 541 connected to the output end of the rotary drive 53. Each end of the clamping cylinder 541 is connected to a set of clamping plates 542. The clamping plates 542 move relative to each other under the action of the clamping cylinder 541, clamping the product from both sides. The two sets of clamping plates 542 are connected to the clamping cylinder 541 via slide rails to ensure the stability of the movement of the clamping plates 542.

[0042] A lower support plate 543 is installed at the lower end between the two sets of clamping plates 542 to support the lower surface of the product and prevent it from falling during transfer. An L-shaped upper support plate 544 is bolted to the inner side of each clamping plate 542. One edge of the upper support plate 544 contacts the upper surface of the product. When the product is flipped, this edge provides bottom support, preventing the product from falling. The upper support plate 544 and lower support plate 543 reduce the clamping force required to hold the product, preventing damage from excessive clamping force and thus improving the stability of product transfer. Furthermore, the surface of the lower support plate 543 is provided with adsorption holes to adsorb the product onto its surface.

[0043] After the carrier 12 is in place, the flipping component descends to a position roughly equivalent to that of the product on the carrier 12. The carrier 12 makes clearance arrangements for the upper support plate 544 and the lower support plate 543 so that the product can enter between the two clamping plates 542 without being interfered with. The clamping cylinder 541 is activated to fix the position of the product and then transfer it to the transfer frame 6.

[0044] The film-applying robot 4 is a four-axis articulated robot, which is advantageous for high-speed operation within a short distance. The output end of the film-applying robot 4 is equipped with a film-applying assembly 41. The film-applying assembly 41 adopts a linkage structure, including a third support 42 and a fourth support 43. An adsorption plate 44 is provided on the fourth support 43, which picks up the film from the feeding mechanism by adsorption. The feeding mechanism is used to provide the required film (not shown in the figure). When the film contacts the product, the adsorption plate 44 stops adsorption, and the film is transferred to the product surface. A roller 45 is provided at one end of the adsorption plate 44. The roller 45 is the end-effector of the film-applying process. It contacts the film and moves from one end of the film to the other, applying a pressing force to the film onto the product.

[0045] The third support 42 is the basic load-bearing structure of the film application assembly 41 and is fixedly installed at the output end of the film application robot 4. The fourth support 43 is slidably connected to the third support 42 and provides support for the adsorption plate 44 and the roller 45. When the roller 45 applies pressure to the film, the third support 42 will move relative to the fourth support 43 to achieve flexible pressure on the film and avoid damaging the product. A spring 46 is provided between the third support 42 and the fourth support 43 to provide buffering for the pressure application process and further ensure the uniformity and flexibility of the pressure application process.

[0046] The rotation of the adsorption plate 44 is driven by the connecting rod cylinder 47. The cylinder body of the connecting rod cylinder 47 is rotatably connected to the fourth bracket 43, and the output shaft is rotatably connected to the adsorption plate 44. The adsorption plate 44, the fourth bracket 43, and the connecting rod cylinder 47 form a connecting rod structure, which converts the linear motion of the connecting rod cylinder 47 into the rotational pressing motion of the rolling wheel 45, thereby realizing a controllable rolling action.

[0047] Furthermore, a detection mechanism 7 is provided between the product dust removal mechanism 2 and the electrostatic dust removal mechanism 3 to perform visual identification on the product after film application. If the product is identified as a good product, it is transferred to the electrostatic dust removal mechanism 3; if the product is identified as a defective product, it is moved in the opposite direction for rejection.

[0048] The working process of this utility model is as follows: The product to be coated is first placed on the carrier 12 of the conveyor 1 and driven forward by the linear motor 11; after entering the product dust removal station, the rubber roller 23 rolls and contacts the product surface with the cooperation of the pressure roller 24 to adhere and remove larger dust or debris particles. At the same time, the transmission roller assembly drives the cleaning cloth 25 to clean the surface of the rubber roller 23, keeping it clean and reusable; after the product dust removal is completed, the product continues to move to the coating station, where the coating robot 4 drives the coating assembly 41 to move and picks up the film from the feeding mechanism by vacuum adsorption, and then rolls it from one end to the other by the rolling roller 45 in a "line contact" manner. Applying pressure, the film is attached to the product surface; after film application, the product is identified as good or defective by the inspection mechanism 7. Good products continue to the electrostatic dust removal station, where the ion air cleaning mechanism 31 generates an ion airflow to blow onto the product, neutralizing the static electricity on its surface; then the product arrives at the end of the production line, and the clamping component 54 of the flipping mechanism 5 moves to the top of the carrier 12 under the drive of the lifting module 51 and the longitudinal movement module. The product is clamped by the clamping plate 542 and the upper and lower support plates, and then the rotating drive component 53 drives the flipping action to transfer it to the transfer frame 6 of the transfer station; finally, the unloading robot 8 removes the product and sends it to the next process, completing the fully automatic film application process.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
