Description

Technical Field

[0001] This invention belongs to the field of visual inspection technology, specifically relating to a die-cutting inspection device for protective films of electronic products. Background Technology

[0002] Visual inspection of electronic product protective films (such as PET, PE, and TPU materials) after die-cutting is a technology that uses machine vision systems to automatically and accurately inspect the dimensional accuracy and appearance defects of die-cut parts. Its core objective is to replace manual visual inspection, improve inspection efficiency and consistency, and adapt to the high-speed and high-yield production needs of the 3C industry.

[0003] Currently, during the die-cutting process of electronic product protective films, friction exists between the electronic product protective film and the die-cutting equipment and the die-cutting inspection equipment, which causes the electronic product protective film to acquire static electricity. This results in the adsorption of dust and other fine impurities on the electronic product protective film. The presence of these fine impurities will affect the clarity of the images captured by the visual inspection camera, thereby affecting the inspection accuracy. Based on this, a die-cutting inspection device for electronic product protective films is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a reasonably designed die-cutting and inspection device for protective films of electronic products in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A die-cutting inspection device for protective films of electronic products includes an inspection base, an inspection box, and a vision inspection camera disposed within the inspection box. The inspection base is equipped with a conveying mechanism for conveying the protective film. An adjusting mechanism is fixedly connected to the inspection base for adjusting the tension of the protective film. The conveying mechanism is configured in two sets: one set is fixedly connected to the inspection base, and the other set is threadedly connected to the adjusting mechanism and then slidably connected to the inspection base. Both sets of conveying mechanisms are used to adjust the tension of the protective film located directly below the vision inspection camera. The testing box is equipped with a leveling mechanism for leveling the protective film of electronic products, and a spraying mechanism for reducing static electricity on the protective film of electronic products.

[0006] As a further optimization of the present invention, the spraying mechanism includes a liquid tank fixedly connected to the top of the detection box, a piston cylinder fixedly connected inside the detection box, an inlet pipe fixedly connected to the top of the piston cylinder, the inlet pipe being fixedly connected to the liquid tank, a piston plate being slidably connected inside the piston cylinder, a piston rod being fixedly connected to the piston plate, the piston rod being slidably connected to the piston cylinder, a water inlet hole being opened at one end of the piston rod located on the piston plate, a spray pipe being fixedly connected to the other end of the piston rod, and an atomizing nozzle being installed at the bottom of the spray pipe.

[0007] As a further optimization of the present invention, the leveling mechanism includes a servo motor mounted on the detection box via a motor mount. The output end of the servo motor is fixedly connected to a first screw, and a second screw is fixedly connected to the first screw via a transmission assembly. A leveling plate is threaded through both the first screw and the second screw.

[0008] As a further optimization of the present invention, the first screw passes through the detection box and is rotatably connected to the detection box, the piston rod is fixedly connected to the plate, and the spray pipe is fixedly connected to the plate.

[0009] As a further optimization of the present invention, the transmission assembly includes a main synchronous pulley fixedly connected to a first screw, a driven synchronous pulley fixedly connected to one end of the second screw, and a synchronous belt tensioned on the main synchronous pulley and the driven synchronous pulley.

[0010] As a further optimization of the present invention, the conveying mechanism includes a mounting frame, on which a conveying motor is fixedly connected. An upper conveying shaft is fixedly connected to the output end of the conveying motor, and an upper gear is fixedly connected to one end of the upper conveying shaft. A lower conveying shaft is rotatably connected to the mounting frame, and a lower gear is fixedly connected to one end of the lower conveying shaft. The lower gear meshes with the upper gear.

[0011] As a further optimization of the present invention, one set of the mounting brackets of the conveying mechanism is fixedly connected to the detection seat, and the other set of the mounting brackets of the conveying mechanism is slidably connected to the detection seat.

[0012] As a further optimization of the present invention, the adjustment mechanism includes a fixed plate fixedly connected to the detection seat, a sliding groove provided on the fixed plate, a sliding plate slidably connected in the sliding groove, an adjustment roller rotatably connected to one side of the sliding plate, and an adjustment plate fixedly connected to the other side. An electric lead screw is fixedly connected to the detection seat, the electric lead screw passes through a mounting bracket slidably connected to the detection seat, a first bevel gear is fixedly connected to the electric lead screw, an adjustment screw is rotatably connected to the fixed plate, the adjustment screw passes through the adjustment plate and is threadedly connected to the adjustment plate, and the bottom of the adjustment screw is fixedly connected to a second bevel gear, the second bevel gear meshing with the first bevel gear.

[0013] As a further optimization of the present invention, an electric telescopic rod is fixedly connected to the top of the detection seat, a backlight heating plate is fixedly connected to the output end of the electric telescopic rod, a baffle is fixedly connected to the backlight heating plate, a drainage groove is provided on the backlight heating plate, and the backlight heating plate is located inside the detection box.

[0014] As a further optimization of the present invention, a front guide roller is rotatably connected to the detection seat, a rear guide roller is rotatably connected to the detection seat, the detection box is fixedly connected to the top of the detection seat, a controller is fixedly connected to the detection box, an electric telescopic rod is fixedly connected to the middle of the detection box, a lifting plate is fixedly connected to the output end of the electric telescopic rod, and the visual inspection camera is fixedly connected to the bottom of the lifting plate.

[0015] The beneficial effects of this invention are as follows: 1. This invention utilizes a spraying mechanism and a leveling mechanism in combination. An antistatic liquid is sprayed onto the die-cut protective film of electronic products through an atomizing nozzle. This process amplifies and reveals minute defects on the protective film, while simultaneously eliminating static electricity adhering to the film, reducing the probability of fine dust adsorption. Furthermore, as the leveling plate moves to both sides, the sprayed antistatic liquid is concentrated, ensuring that it remains abundantly only at the defect sites, with minimal residue on the outer surface of the protective film. This avoids excessive antistatic liquid coverage that could affect detection accuracy.

[0016] 2. The present invention, through the setting of the leveling mechanism, enables the die-cut electronic product protective film to be flatly adhered to the backlight heating plate, avoiding wrinkles and stacking of the die-cut electronic product protective film, which would affect the detection accuracy. At the same time, it can also prevent air bubbles from existing between the die-cut electronic product protective film and the backlight heating plate, which would cause inconsistent distances between the die-cut electronic product protective film and the lens of the visual inspection camera, resulting in local blurring of the captured image. This further improves the clarity of the captured image and enhances the detection accuracy.

[0017] 3. This invention, through the setting of the adjustment mechanism, allows the die-cut electronic product protective film located on the backlight heating plate to be in a slightly relaxed state, thereby eliminating dimensional detection errors caused by stretching deformation. Simultaneously, it can accurately expose minor burrs, chipped edges, or corner gaps that are easily generated by tool wear and uneven pressure during the die-cutting process. Furthermore, it prevents tiny air bubbles, local wrinkles, or uneven adhesive layer thickness within the electronic product protective film from being dispersed and flattened due to stretching after tensioning. This allows the visual inspection camera to accurately capture images of the die-cut electronic product protective film, improving inspection accuracy and ensuring inspection quality. At the same time, it prevents further stretching of the electronic product protective film between the upper and lower conveyor shafts and the adjusting roller, thus avoiding damage to the electronic product protective film and providing excellent protection.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a die-cutting inspection device for protective films of electronic products includes an inspection base 1, an inspection box 2, and a visual inspection camera 5 installed inside the inspection box 2. An electric telescopic rod 111 is fixedly connected to the top of the inspection base 1. A backlight heating plate 11 is fixedly connected to the output end of the electric telescopic rod 111. A heating wire is installed inside the backlight heating plate 11, and a temperature sensor is installed on the backlight heating plate 11. The heating wire is used to heat the backlight heating plate 11. The heating wire, in conjunction with the temperature sensor, controls the heating temperature of the backlight heating plate 11 to approximately 25°C (the temperature sensor and heating wire are existing technologies and are not shown in the figure, so they will not be described in detail). This reduces the impact of temperature differences on the inspection, thereby improving the inspection accuracy. A baffle 12 is fixedly connected to the backlight heating plate 11, and a drainage groove 13 is formed on the backlight heating plate 11. The backlight heating plate 11 is located inside the inspection box 2. A front guide roller 7 and a rear guide roller 10 are rotatably connected to the inspection base 1. The inspection box 2 is fixedly connected to the top of the inspection base 1, and a control device is fixedly connected to the inspection box 2. The controller 6 is used to control the operation of the die-cutting inspection equipment. An electric telescopic rod 3 is fixedly connected to the middle of the inspection box 2. A lifting plate 4 is fixedly connected to the output end of the electric telescopic rod 3. A visual inspection camera 5 is fixedly connected to the bottom of the lifting plate 4. Two sets of conveying mechanisms 8 are provided on the inspection seat 1. The conveying mechanisms 8 are used to convey the electronic product protective film. The conveying mechanism 8 includes a mounting frame 86. A conveying motor 81 is fixedly connected to the mounting frame 86. An upper conveying shaft 82 is fixedly connected to the output end of the conveying motor 81. An upper gear 83 is fixedly connected to one end of the upper conveying shaft 82. A lower conveying shaft 85 is rotatably connected to the mounting frame 86. A lower gear 84 is fixedly connected to one end of the lower conveying shaft 85. The lower gear 84 meshes with the upper gear 83. The mounting frame 86 of one set of conveying mechanisms 8 is fixedly connected to the inspection seat 1. The mounting frame 86 of the other set of conveying mechanisms 8 is slidably connected to the inspection seat 1. An adjustment mechanism 9 is fixedly connected to the inspection seat 1. The adjustment mechanism 9 is used to adjust the tension of the electronic product protective film in conjunction with the conveying mechanism 8.

[0022] In use, the die-cut electronic product protective film to be inspected is passed sequentially through the front guide roller 7, a set of conveying mechanisms 8, the backlight heating plate 11, another set of conveying mechanisms 8, the adjusting mechanism 9, and the rear guide roller 10, and connected to the external winding device. At this time, the die-cut electronic product protective film is limited to the two baffles 12. During inspection, the conveying motor 81 is started so that the upper conveying shaft 82 and the lower conveying shaft 85 intermittently convey the die-cut electronic product protective film. When the conveying stops, the electric telescopic rod 3 is started, and the distance between the vision inspection camera 5 and the die-cut electronic product protective film is adjusted by the lifting plate 4. Then, the vision inspection camera 5 can be started to take pictures of the die-cut electronic product protective film. The controller 6 receives the captured pictures and analyzes whether there are defects in the die-cut electronic product protective film.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the adjustment mechanism 9 includes a fixed plate 91 fixedly connected to the detection seat 1. A slide groove 92 is provided on the fixed plate 91. A slide plate 93 is slidably connected in the slide groove 92. An adjustment roller 94 is rotatably connected to one side of the slide plate 93, and an adjustment plate 95 is fixedly connected to the other side. An electric lead screw 96 is fixedly connected to the detection seat 1. The electric lead screw 96 is threaded through the mounting bracket 86 which is slidably connected to the detection seat 1. A first bevel gear 97 is fixedly connected to the electric lead screw 96. An adjustment screw 99 is rotatably connected to the fixed plate 91. The adjustment screw 99 is threaded through the adjustment plate 95. The bottom of the adjustment screw 99 is fixedly connected to a second bevel gear 98. The second bevel gear 98 meshes with the first bevel gear 97.

[0024] When the die-cut electronic product protective film is stopped and inspection begins, the electric lead screw 96 is activated, causing the mounting bracket 86, which is slidably connected to the inspection seat 1, to slide towards the backlight heating plate 11. This allows the die-cut electronic product protective film on the backlight heating plate 11 to be in a slightly relaxed state, thereby eliminating dimensional inspection errors caused by stretching deformation. Simultaneously, it accurately exposes minor burrs, chipped edges, or corner gaps that can easily occur due to tool wear and uneven pressure during the die-cutting process. Furthermore, it prevents the dispersion of tiny air bubbles, localized wrinkles, or uneven adhesive layer thickness within the adhesive layer after the electronic product protective film has been stretched. The film is flattened, allowing the visual inspection camera 5 to accurately capture images of the die-cut electronic product protective film, improving inspection accuracy and ensuring inspection quality. At the same time, the electric lead screw 96 drives the adjusting screw 99 to rotate through the first bevel gear 97 and the second bevel gear 98. This causes the adjusting plate 95 to move downwards through the sliding plate 93, thereby preventing further stretching of the electronic product protective film between the upper conveyor shaft 82, the lower conveyor shaft 85, and the adjusting roller 94, which could lead to damage to the electronic product protective film. This provides good protection for the electronic product protective film.

[0025] like Figure 2 , Figure 3 , Figure 6 , Figure 8 and Figure 9As shown, a leveling mechanism 14 for leveling the protective film of electronic products is fixedly connected to the testing box 2. The leveling mechanism 14 includes a servo motor 141 mounted on the testing box 2 via a motor mount. A first screw 142 is fixedly connected to the output end of the servo motor 141. The first screw 142 passes through the testing box 2 and is rotatably connected to the testing box 2. A second screw 146 is connected to the first screw 142 via a transmission assembly. The second screw 146 is rotatably connected to the testing box 2. A leveling plate 147 is threaded through both the first screw 142 and the second screw 146. The bottom of the leveling plate 147 is made of a soft material. The transmission assembly includes a main synchronous pulley 143 fixedly connected to the first screw 142. A driven synchronous pulley 145 is fixedly connected to one end of the second screw 146. A synchronous belt 144 is tensioned on the main synchronous pulley 143 and the driven synchronous pulley 145. The main synchronous pulley 143 and the driven synchronous pulley 145 have the same size and specifications.

[0026] After the adjustment mechanism 9 brings the die-cut electronic product protective film to a normal state, the servo motor 141 is activated to rotate the first screw 142, which in turn causes the second screw 146 to rotate synchronously and at the same speed through the transmission assembly. This causes the two flat plates 147 to slide to both sides, flattening the die-cut electronic product protective film and ensuring it adheres smoothly to the backlight heating plate 11. This prevents wrinkles and stacking of the die-cut electronic product protective film, which would affect detection accuracy. It also prevents air bubbles between the die-cut electronic product protective film and the backlight heating plate 11, which could cause inconsistencies in the distance between the die-cut electronic product protective film and the lens of the visual inspection camera 5, resulting in partial blurring of the captured image. This further improves the clarity of the captured image and enhances detection accuracy.

[0027] like Figure 3 , Figure 6 , Figure 8 and Figure 9As shown, a spray mechanism 15 for weakening static electricity on the protective film of electronic products is fixedly connected to the test box 2. The spray mechanism 15 includes a liquid tank 151 fixedly connected to the top of the test box 2. The top of the liquid tank 151 has a liquid filling port. A piston cylinder 153 is fixedly connected inside the test box 2. The top of the piston cylinder 153 is fixedly connected to a liquid inlet pipe 152. A one-way valve is installed in the liquid inlet pipe 152, so that the piston cylinder 153 can only draw liquid through the liquid inlet pipe 152. The liquid inlet pipe 152 is fixedly connected to the liquid tank 151. A piston plate is slidably connected inside the piston cylinder 153. 154. A piston rod 155 is fixedly connected to the piston plate 154. A one-way valve is installed inside the piston rod 155, so that the liquid in the piston cylinder 153 can only be discharged through the piston rod 155. The piston rod 155 is fixedly connected to the plate 147. The piston rod 155 and the piston cylinder 153 are in a sealed sliding connection. A water inlet hole 156 is opened at one end of the piston rod 155 located on the piston plate 154. A spray pipe 157 is fixedly connected to the other end of the piston rod 155. The spray pipe 157 is fixedly connected to the plate 147. An atomizing nozzle 158 is installed at the bottom of the spray pipe 157.

[0028] As the plate 147 moves to both sides, it drives the piston rod 155 to pull the piston plate 154 outward from the piston cylinder 153. This allows the antistatic liquid in the piston cylinder 153 to enter the piston rod 155 through the water inlet 156, then into the spray pipe 157, and finally sprayed onto the die-cut electronic product protective film through the atomizing nozzle 158. On the one hand, this allows some minor defects on the electronic product protective film to be magnified and displayed by the droplets. On the other hand, it allows the static electricity attached to the electronic product protective film to be eliminated by the antistatic liquid. During this process, the plate 147 moves to both sides, and the atomizing nozzle 158 is on the forward side of the plate 147. Therefore, the plate 147 can concentrate the sprayed antistatic liquid, so that the antistatic liquid only remains in large quantities at the defect sites, while less remains on the outer surface of the electronic product protective film. This avoids the large coverage of antistatic liquid affecting the detection accuracy. When the plate 147 moves to the edge, it pushes the concentrated antistatic liquid into the drainage trough 13.

[0029] The specific working principle of this invention is as follows: In use, the die-cut protective film for electronic products to be inspected is sequentially passed through the front guide roller 7, a set of conveying mechanisms 8, the backlight heating plate 11, another set of conveying mechanisms 8, the adjusting mechanism 9, and the rear guide roller 10, and connected to the external winding device. At this time, the die-cut protective film adheres to both sides of the baffle 12. During inspection, the conveying motor 81 is started so that the upper conveying shaft 82 and the lower conveying shaft 85 intermittently convey the die-cut protective film. When the conveying stops, the electric telescopic rod 3 is started to adjust the distance between the vision inspection camera 5 and the die-cut protective film through the lifting plate 4. At the same time, the electric lead screw 96 is started so that the mounting bracket 86, which is slidably connected to the inspection seat 1, slides towards the backlight heating plate 11, so that the die-cut protective film on the backlight heating plate 11 is in a slightly relaxed state, thereby eliminating the dimensional inspection caused by stretching deformation. The system measures and accurately exposes minor burrs, chipped edges, or corner gaps caused by tool wear and uneven pressure during the die-cutting process. It also prevents tiny air bubbles, localized wrinkles, or uneven adhesive thickness within the adhesive layer from spreading and flattening due to stretching after the electronic product protective film is stretched. This allows the visual inspection camera 5 to accurately capture images of the die-cut electronic product protective film, improving inspection accuracy and ensuring inspection quality. Simultaneously, the electric lead screw 96 drives the adjusting screw 99 to rotate via the first bevel gear 97 and the second bevel gear 98. This causes the adjusting plate 95, under the rotation of the adjusting screw 99, to move the adjusting roller 94 downwards via the sliding plate 93. This prevents further stretching of the electronic product protective film between the upper conveyor shaft 82, the lower conveyor shaft 85, and the adjusting roller 94, thus protecting the electronic product protective film effectively. After the adjustment mechanism 9 brings the die-cut electronic product protective film to a normal state, the servo motor 141 is activated to rotate the first screw 142, which in turn causes the second screw 146 to rotate synchronously and at the same speed through the transmission component. This causes the two flat plates 147 to slide to both sides, flattening the die-cut electronic product protective film and ensuring that it adheres smoothly to the backlight heating plate 11. This prevents the die-cut electronic product protective film from being wrinkled or stacked, which would affect the detection accuracy. It also prevents air bubbles between the die-cut electronic product protective film and the backlight heating plate 11, which would cause the distance between the die-cut electronic product protective film and the lens of the visual inspection camera 5 to be inconsistent, resulting in partial blurring of the captured image. This further improves the clarity of the captured image and the detection accuracy. After flattening, the electric telescopic rod 111 is activated to lower the backlight heating plate 11 by a certain distance. Meanwhile, as the plate 147 moves to both sides, it will drive the piston rod 155 to pull the piston plate 154 to slide out of the piston cylinder 153, so that the antistatic liquid in the piston cylinder 153 enters the piston rod 155 through the water inlet 156, and then enters the spray pipe 157. Finally, it sprays the antistatic liquid onto the die-cut electronic product protective film through the atomizing nozzle 158. On the one hand, it can magnify and show some minor defects on the electronic product protective film by the droplets. On the other hand, it can eliminate the static electricity attached to the electronic product protective film by the antistatic liquid. In this process, the plate 147 moves to both sides, and the atomizing nozzle 158 is on the forward side of the plate 147. Therefore, the plate 147 can gather the sprayed antistatic liquid, so that the antistatic liquid is only left in large quantities at the defect, while less remains on the outer surface of the electronic product protective film. This avoids the large coverage of antistatic liquid affecting the detection accuracy. When the plate 147 moves to the edge, it will push the gathered antistatic liquid into the drainage tank 13. Then the visual inspection camera 5 can be activated to capture images of the die-cut electronic product protective film. The controller 6 receives the captured images and analyzes whether there are any defects in the die-cut electronic product protective film. After the shooting is completed (at this time, the backlight heating plate 11 descends a certain distance so that the entire plate 147 is not tightly attached to the electronic product protective film, so as to avoid the electronic product protective film being carried inward when the entire plate 147 moves inward, causing the electronic product protective film to wrinkle inward, and avoiding the situation of the electronic product protective film being squeezed and damaged), the servo motor 141 is started to move the entire plate 147 on both sides inward, and then the piston plate 154 is pushed into the piston cylinder 153 by the piston rod 155, so that the piston cylinder 153 draws the antistatic liquid in the liquid tank 151 through the liquid inlet pipe 152 until the two entire plates 147 are attached together, and when the next die-cutting inspection part of the electronic product protective film reaches directly below the visual inspection camera 5, the electric telescopic rod 111 is started to move the backlight heating plate 11 upward, so that the entire plate 147 and the electronic product protective film are reattached.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
