Description

Technical Field

[0001] The present invention relates to a processing device for a light guide plate and its process flow, in particular to a circular light guide plate processing and laminating process and its laminating and packaging device. Background Art

[0002] Since the light guide plate is made of acrylic material and mostly has irregular shapes, the light guide plate is generally injection-molded. And the light transmission of the light guide plate is carried out by using the light guide points engraved on the surface. The deviation between the shape of the light guide plate and the design, the appearance of abnormal scratches or depressions on the surface of the light guide plate, etc. will seriously affect the practical situation of the light guide plate. Therefore, it is necessary to process and package the injection-molded light guide plate to ensure the performance of the light guide plate. When processing the injection-molded light guide plate, generally, workers manually move the light guide plate from the injection station to the cutting station for cutting, and then move it to the laminating station for laminating. Multiple manual operations are required during the processing, wasting a lot of manpower and having low production efficiency. Moreover, the structure of the laminating machine cannot automatically laminate special-shaped light guide plates such as circular ones, resulting in low production quality. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an overall automated processing, packaging, and collection process for a light guide plate, as well as a light guide plate laminating device that integrates a laminating reel, a pressing device, a cutting device, and a clamping device to achieve automated laminating.

[0035] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflict.

[0036] Refer to Figure 1 , Figure 2 , a circular light guide plate processing and film covering process, which is characterized in that it includes the following steps:

[0037] Step 1: Injection molding. When injection molding, the original two-way gate is changed to a vertical one-way gate to facilitate subsequent cutting processing;

[0038] Step 2: Cut the gate by using an automatic cutting device. First, use the manipulator on the automatic cutting machine to suck the injection-molded light guide plate, and then place it at the cutting position for cutting. The cutting time for each gate is 1 second. The automated processing steps save labor costs while improving production efficiency and quality;

[0039] Step 3: Remove static electricity and cool the cut light guide plate. The cooling time is 10 seconds;

[0040] Step 4: Automatically laminate the light guide plate using the light guide plate laminating and packaging equipment;

[0041] Step 5, the collecting part 8 automatically collects the finished products. When the finished products are stacked on the collecting plate 81 of the laminating and packaging equipment, each time a product is stacked, the collecting plate 81 will automatically descend under the influence of gravity. When the descending height exceeds 0.4 meters, the height sensor is triggered, and the laminating and packaging equipment pauses and emits an alarm sound to notify the on-site personnel to remove the finished products. The on-site personnel put the finished products into the packing boxes for packaging and shipping. Compared with taking the goods once for each processed product, the downtime during the machine processing is reduced, and the production efficiency is further improved.

[0042] Refer to Figure 2 , a circular light guide plate laminating and packaging equipment used in Step 4, including a supporting part 1, a conveying part, a laminating part, and a collecting part 8. The conveying part, the laminating part, and the collecting part 8 are all arranged on the supporting part 1. The conveying part is located in front of the laminating part and is used to transport the cut light guide plate to the laminating part. The collecting part 8 is located behind the laminating part and is used to collect the laminated light guide plate; the conveying part includes a bottom conveying part 2 and a top conveying part 3. The laminating part includes a laminating reel 4, a pressing device 5, a cutting device 6, and a clamping device 7. The automatic cutting device used in Step 2 is integrally arranged with the laminating and packaging equipment and is connected through the conveying part on the laminating and packaging equipment. By arranging the conveying part on the laminating device integrated with the laminating reel 4, the pressing device 5, the cutting device 6, and the clamping device 7, the automatic control of the light guide plate by the laminating and packaging equipment can be realized, omitting the labor consumption and time consumption of the light guide plate from one processing procedure to another. Moreover, the mechanized conveying part is more accurate in the placement position compared with manual movement, improving the efficiency and quality of the light guide plate processing and laminating.

[0043] Refer to Figure 3 , the supporting part 1 includes a supporting frame 11, a supporting panel 12 arranged on the supporting frame 11, and supporting legs 13 and supporting wheels 14 arranged at the bottom of the supporting frame 11. Adjusting screws are provided on the supporting legs 13, and the height of the supporting legs 13 can be adjusted by rotating the adjusting screws. The supporting wheels 14 are arranged beside the supporting legs 13. When the position of the equipment needs to be moved, the height of the supporting legs 13 can be adjusted so that the height of the supporting legs 13 is less than the height of the supporting wheels 14. At this time, by pushing the equipment, the supporting wheels 14 can drive the equipment to move. When the equipment moves to the appropriate position, the height of the supporting legs 13 is adjusted again so that the height of the supporting legs 13 is greater than the height of the supporting wheels 14, and the equipment is fixed to the ground through the supporting legs 13. This makes the movement and adjustment of the equipment more convenient.

[0044] Refer to Figure 4 , Figure 5, the top conveying part 3 is arranged above the bottom conveying part 2, the head end of the top conveying part 3 corresponds to the tail end of the bottom conveying part 2, the bottom conveying part 2 includes a bottom conveying frame 21, a conveyor belt and a conveying fixture 22, and a slide rail and a slider arranged at the bottom of the conveying fixture 22. The bottom conveying frame 21 is arranged at the end of the supporting part 1. The top conveying part 3 includes a horizontal conveying frame 31, a vertical conveying frame 32, a conveyor belt and a vacuum suction cup 33. Above the vacuum suction cup 33, there are also a vertical lifting cylinder 34 and a rotating cylinder 35. The rotating cylinder 35 is arranged at the bottom of the vertical lifting cylinder 34, and the vacuum suction cup 33 is arranged at the bottom of the rotating cylinder 35. The vertical lifting cylinder 34 is connected to the vertical conveying frame 32 through a slide rail and a slider. The vertical conveying frame 32 is correspondingly arranged on the horizontal conveying frame 31 through a slide rail and a slider and is driven by a conveyor belt. One end of the bottom conveying part 2 extends into the automatic cutting equipment, and the cut light guide plate is directly transported to the film covering and packaging equipment inside the automatic cutting equipment. At the top conveying equipment at one end of the bottom conveying equipment, after being sucked by the top conveying equipment, it is sent to the film covering place for automatic film covering treatment.

[0045] Refer to Figure 4 , Figure 6 , the film covering reel 4 includes an upper film covering reel 41 and a lower film covering reel 42. Below the upper film covering reel 41, in front of the front side edge of the pressing plate 51 and in front of the supporting frame 11, there is also an auxiliary reel 43 for assisting the upper film covering reel 41 and the lower film covering reel 42. The lower film covering reel 42 is arranged below the bottom conveying part 2, and the upper film covering reel 41 is arranged above the pressing device 5. The films on the two film covering reels 4 are respectively attached together below the pressing device 5 through two auxiliary reels 43 parallel to the processing plane, and can directly cover both sides of the light guide plate to wrap the light guide plate, simplifying the process of wrapping the light guide plate with the film.

[0046] Refer to Figure 6 , the pressing device 5 includes a pressing plate 51 and a pressing cylinder 52 arranged at the bottom of the pressing plate 51. The pressing cylinder 52 is arranged on both sides of the pressing plate 51 and is used to drive the pressing plate 51 to lift and lower. When the light guide plate needs to pass through the pressing device 5, the pressing cylinder 52 rises to lift the pressing plate 51 arranged on the pressing cylinder 52. After the light guide plate passes through the pressing device 5 along with the films on both sides, the pressing cylinder 52 is started again to drive the pressing plate 51 downward, so that the pressing plate 51 presses on the two layers of films to fix the two layers of films.

[0047] The clamping device 7 includes a clamping cylinder 71, a clamping claw 72, a support frame and a transverse driving part 75. The support frame includes a transverse supporting frame 73 and a vertical supporting frame 74. The transverse driving part 75 is arranged on the transverse supporting frame 73. The vertical supporting frame 74 is arranged in an "L" shape. One end of the "L"-shaped vertical supporting frame 74 is connected to the transverse driving part 75, and the other end is used to fix the clamping cylinder 71. The transverse driving part 75 includes a conveyor belt and transverse slide rails and transverse sliders arranged on both sides of the conveyor belt. The transverse slider is fixed at one end of the support frame, and the vertical supporting frame 74 is also fixedly connected to the conveyor belt through a connecting block. When the light guide plate is placed between the two layers of film, the clamping cylinder 71 drives the clamping claw 72 to clamp the edge of the film, and then starts the horizontal driving part 75. The horizontal slider on the horizontal driving part 75 drives the vertical support frame 74 and the clamping claw 72 set on the vertical support frame 74 to move on the horizontal slide rail, thereby driving the light guide plate and the film to move together, so that the film is completely wrapped on the light guide plate, realizing the rapid wrapping process of the light guide plate, and at the same time adjusting the position of the light guide plate to facilitate the next step of operation.

[0048] The cutting device 6 includes a top pressure plate 61, a bottom support plate 62, and a cutting plate 63 mounted on the top pressure plate 61. The cutting plate 63 is retracted and arranged on the top pressure plate 61 by a cylinder. The top pressure plate 61 is mounted on a transverse support frame 73 by a cylinder, and the bottom support plate 62 is mounted on the support panel 12 by a cylinder and a slide rod. After the light guide plate is pulled out of the range of the support panel 12 by the clamping device 7, the bottom support plate 62 at the bottom of the light guide plate rises, lifting the light guide plate covered with the film. Then, the top pressure plate 61 located directly above the light guide plate falls and presses against the light guide plate, compacting the film on the light guide plate. At the same time, the cutting plate mounted on the top pressure plate 61 descends together with the top pressure plate 61. After the top pressure plate 61 compacts the film, the cutting plate 63 continues to extend downward by the cylinder, cutting the film, completing the lamination process of the light guide plate.

[0049] The collection section 8 described in step 5 includes a collection plate 81, a support plate, and a buffer column 82 mounted on the support plate to support the collection plate 81. The buffer column 82 is also equipped with a height sensor. As finished products are stacked on the collection plate 81 of the film packaging machine by the clamp 72, the buffer column 82 supporting the collection plate 81 automatically descends under the influence of gravity with each product stacked. When the descent exceeds 0.4 meters, the height sensor is triggered, causing the film packaging machine to pause and sound an alarm to notify on-site personnel to remove the finished product. The on-site personnel then place the finished product into a packaging box for shipment. This reduces downtime during machine processing, compared to removing products as each product is processed, further improving production efficiency.
