Description

Technical Field

[0001] The present invention relates to the technical field of shading film detection, and in particular to an automatic shading film detection device. Background Art

[0002] Light-shielding film is usually used in optical devices to block the entry of external light. An ideal light-shielding film can completely absorb ambient light and achieve zero reflection. Light-shielding film products are composed of three parts: base film, light-shielding film and upper dust-proof film. The thickness ranges from 0.5mm to 0.75mm. The upper dust-proof film and base film play a role in fixing and dust prevention. During the silk-screen printing process before the product is formed, the light-shielding film may leak ink (that is, the ink seeps from the silk-screen screen to the film material, generally in the middle of the side), drop ink (that is, there is a small blank without ink on the border of the silk-screen printing), and overflow ink (that is, there is ink protruding from the edge line to the middle during silk-screen printing). When the size of the ink leakage, ink drop, and ink overflow is greater than 20 microns, it is an unqualified product and the light-shielding film needs to be tested. The manual detection method is labor-intensive, inefficient, and easy to miss, which is difficult to meet the needs of industrial production.

[0029] like Figure 1 As shown, an embodiment of the present invention provides an automatic light shielding film detection device, including a product feeding component 100, a glue feeding component 200, a mold clamping and parting component 300, a detection component 400, a defective product removal component 500, an upper dustproof film feeding component 600 and a rear mold clamping component 700. Figure 2As shown, the shading film product consists of three parts: a bonded bottom film 801, a shading film 802 and an upper dustproof film 803. The upper dustproof film 803 and the bottom film 801 play a role in fixing and dustproofing. The product feeding component 100 continuously conveys the product to be inspected to the mold clamping and parting component 300, and the adhesive material feeding component 200 continuously conveys adhesive material, such as transparent tape, to the mold clamping and parting component 300. The mold clamping and parting component 300 makes the adhesive material adhere to the upper dustproof film 803 of the product, and then separates the upper dustproof film 803 from the shading film 802 and the bottom film 801. The separated shading film 802 is conveyed to the inspection component 400 with the bottom film 801 for ink inspection. After judging the ink dot size and confirming good products and defective products, it is conveyed to the defective product removal component 500. The defective product is removed. Component 500 removes the shading film 802 identified as defective, while the good product continues to move with the base film 801 to the rear mold assembly 700. The upper dustproof film loading component 600 simultaneously continuously transports the upper dustproof film 803 to the rear mold assembly 700. The rear mold assembly 700 bonds the upper dustproof film 803 to the shading film 802 and the base film 801 to form a complete product again. The product is finally wound and collected by the rear part of the product feeding component 100. It is controlled in an automated manner without the need for manual intervention, which effectively improves the efficiency and reliability of shading film product inspection and reduces inspection costs.

[0030] In this embodiment, the product feeding assembly 100 includes a product unloading roller 101 at the front end of the entire device and a product receiving roller 102 at the rear end. The product unloading roller 101 and the product receiving roller 102 are both wound with products. The product receiving roller 102 is provided with a product driving unit, and the product receiving roller 102 is driven by the product driving unit to rotate, thereby continuously reeling the product. During the entire process, the bottom film 801 of the product is continuously conveyed, unloaded and received between the product unloading roller 101 and the product receiving roller 102, and the original upper dustproof film 803 of the product is separated after passing through the mold clamping and parting assembly 300. Subsequently, the new upper dustproof film 803 is loaded and pasted to the light shielding film 802 and the bottom film 801 through the upper dustproof film loading assembly 600. The defective products of the light shielding film 802 confirmed after detection will be taken away by the defective product taking assembly 500, and the good products will continue to be conveyed with the bottom film 801.

[0031] In this embodiment, the adhesive material feeding assembly 200 includes an adhesive material feeding roller 201 and an adhesive material receiving roller 202. The adhesive material feeding roller 201 winds the adhesive material, and the adhesive material receiving roller 202 winds the waste material composed of the adhesive material and the upper dustproof film 803 after separation. The adhesive material receiving roller 202 is provided with an adhesive material driving unit, and the adhesive material receiving roller 202 is driven by the adhesive material driving unit to rotate, so as to continuously reel up the waste material. Therefore, the adhesive material is continuously transported, discharged and received between the adhesive material feeding roller 201 and the adhesive material receiving roller 202, and the upper dustproof film 803 is bonded and fixed by the adhesive material after passing through the mold clamping and parting assembly 300, and its bonding force is greater than the bonding force between the upper dustproof film 803 and the bottom film 801, so after being removed from the mold clamping and parting assembly 300, it is transported to the adhesive material receiving roller 202 with the adhesive material and reeled up.

[0032] In this embodiment, the upper dustproof film feeding assembly 600 includes an upper dustproof film discharge roller, which winds up the upper dustproof film 803 and continuously discharges material toward the rear mold clamping assembly 700 .

[0033] At the same time Figure 3 , Figure 4 As shown, the mold clamping and splitting assembly 300 includes a front mold clamping mounting frame 301 and a splitting mounting frame 305. Among them, a plurality of freely rotating first guide rollers 302 are arranged at both ends of the front mold clamping mounting frame 301, and a first driving roller 303 and a freely rotating first driven roller 304 are arranged in the middle of the front mold clamping mounting frame 301. The product and the adhesive material transported to the mold clamping and splitting assembly 300 are first guided by the corresponding first guide rollers 302, and then moved between the first driving rollers 303 and the first driven rollers 304. The first guide rollers 302 are arranged so that the angle of the product and the adhesive material when transported between the two rollers is appropriate, so that the rollers can press and bond the two together. One end of the first driving roller 303 is connected to the first mold clamping driving unit, and the first driving roller 303 is driven to rotate by the first mold clamping driving unit. The first driving roller 303 and the first driven roller 304 drive the product and the adhesive material to be continuously transported and pressed and bonded, so as to ensure that the adhesive material is firmly bonded to the upper dustproof film 803.

[0034] The mold splitting mounting frame 305 is located at the rear of the front mold closing mounting frame 301. A mold splitting piece 306 is provided on the mold splitting mounting frame 305. The mold splitting piece 306 will press the continuously conveyed product and the adhesive material. After the adhesive material and the bottom film pass through the mold splitting piece 306, they have different conveying directions, so that the upper dustproof film 803 can be smoothly separated from the shading film 802 and the bottom film 801 at the edge of the mold splitting piece 306.

[0035] As a further improvement, a slide groove 307 is provided on the front mold clamping mounting frame 301, and sliders 308 are connected to both ends of the first driven roller 304. The sliders 308 are slidably arranged in the corresponding slide grooves 307. A clamping spring 309 is arranged in the slide grooves 307, and the end of the clamping spring 309 is connected to the slider 308. At the same time, a mold clamping handle 310 is installed at one end of the first driven roller 304. The sliders 308 at both ends of the first driven roller are controlled by the mold clamping handle 310 to slide upward along the slide groove 307, so that the first driven roller 304 is lifted, which is convenient for the installation of products and adhesives during the equipment startup stage. When the product and adhesive are installed in place, the mold clamping handle 310 is released, and the first driven roller 304 moves downward under the action of the clamping springs 309 at both ends, and clamps the product and adhesive with the first active roller 303 by elastic force, ensuring that the adhesive and the upper dustproof film 803 are firmly adhered after passing through the roller.

[0036] Similarly, a mounting shaft 311 is provided on the mold splitting mounting frame 305, and both ends of the mounting shaft 311 are rotatably connected to the mold splitting mounting frame 305, and the middle part of the mounting shaft 311 is fixed to the mold splitting sheet 306. A mold splitting handle 312 is installed at one end of the mounting shaft 311, and a locking bolt 313 for locking the mounting shaft 311 is also provided on the mold splitting mounting frame 305. During installation, the locking bolt 313 is loosened, and then the mold splitting handle 312 is rotated to make the edge of the mold splitting sheet 306 tilt up, leaving space for the product and the adhesive to pass through. After installation, the mold splitting handle 312 is reset so that the edge of the mold splitting sheet 306 presses the product and the adhesive again, and then the locking bolt 313 is tightened to fix it.

[0037] At the same time Figure 5 As shown, the detection assembly 400 includes a detection box 401, the bottom of the detection box 401 is open, and the other surfaces are non-translucent surfaces. The light shielding film 802 and the bottom film 801 pass through the bottom of the detection box 401. Among them, the bottom of the detection box 401 is provided with a light source 402, and the top is provided with a line array camera 403. The light source 402 irradiates downward to provide shooting light. The line array camera 403 is connected to the lifting mechanism 404 installed on the top of the detection box 401, and can be adjusted to a suitable height position to capture the image of the light shielding film 802 below. After the image is transmitted to the system, the good and bad condition of the light shielding film 802 is judged by the algorithm set by the system.

[0038] At the same time Figure 6As shown, the defective material picking assembly 500 includes a picking mounting frame 501, on which a picking displacement module 502 is arranged, and the picking displacement module 502 has two degrees of freedom, namely, lateral movement and lifting. The picking displacement module 502 is connected to a stripping block 503 and a pressing cylinder 504, and the stripping block 503 is formed with an inclined surface 505. When the detection assembly 400 detects and determines that the light shielding film 802 is a defective product and the defective product moves to the bottom of the picking mounting frame 501, the picking displacement module 502 drives the stripping block 503 to descend and then move horizontally, so that the inclined surface 505 of the stripping block 503 scoops up the light shielding film 802 and peels it off from the bottom film 801. As the stripping block 503 continues to move, the light shielding film 802 gradually moves onto the inclined surface 505. When the sensor detects that there is a shading film 802 on the inclined surface 505, the pressing cylinder 504 presses down to press the peeled shading film 802 tightly against the inclined surface 505, and finally the material taking displacement module 502 rises to completely separate the shading film 802 from the bottom film 801, and then moves horizontally to the defective product collection area to discharge the material.

[0039] In this embodiment, the rear mold clamping assembly 700 includes a rear mold clamping mounting frame, and a plurality of freely rotatable second guide rollers are arranged at both ends of the rear mold clamping mounting frame, and a second driving roller and a freely rotatable second driven roller are arranged in the middle of the rear mold clamping mounting frame, and one end of the second driving roller is connected to the second mold clamping driving unit, and the second driving roller is driven to rotate by the second mold clamping driving unit. In addition, the rear mold clamping assembly is also provided with a slider, a clamping spring, etc., which is similar to the structure of the front mold clamping mounting frame 301, and will not be repeated here.

[0040] The equipment provided in this embodiment also includes a conveying frame 900, the first end of which is provided with a first guide mechanism, the second end of which is provided with a second guide mechanism, and the middle part of which is provided with a first vacuum suction plate 901 and a second vacuum suction plate 902. At the same time, as shown in FIG7, the first guide mechanism is located between the product discharge roller 101 and the front mold clamping mounting frame 301, and includes two guide plates 903 arranged opposite to each other and a third guide roller 904 connected between the guide plates 903 and freely rotating, and the front end of the guide plate 903 is provided with a third vacuum suction plate 905, and the vacuum adsorption effect of the third vacuum suction plate 905 allows the product to be fully straightened during transportation, and the guiding effect of the guide plate 903 prevents the product from being deviated. The second guide mechanism is located between the rear mold clamping mounting frame and the product receiving roller 102, and is a curved guide slide plate 906, which provides arc support for the product with the dustproof film 803 reattached. The first vacuum suction plate 901 is located directly below the inspection box 401. Through vacuum suction, the bottom film 801 and the light shielding film 802 are attached to the conveying frame 900 and fully unfolded, which is convenient for image capture. The second vacuum suction plate 902 is located directly below the material picking mounting frame 501. Through vacuum suction, the bottom film 801 and the light shielding film 802 are fixed to ensure that the defective material picking component 500 picks up the defective materials, and the entire bottom film 801 is stopped when picking up the materials.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
