Description

Technical Field

[0001] This utility model relates to the field of automatic film application technology, and in particular to an automatic auxiliary material application device. Background Technology

[0002] Currently, in China's 3C manufacturing automation product auxiliary material application industry, this market share continues to grow with the continuous development of intelligent manufacturing, such as product film application. Traditional film application operations mostly rely on manual labor or semi-automatic equipment, generally suffering from low efficiency, poor consistency, and high requirements for operator proficiency. Although some existing automated equipment can achieve basic picking and placing and applying functions, there are still several obvious limitations in practical applications: On the one hand, the positioning of the material supply and application process mostly relies on mechanical fixation or simple sensors, making it difficult to detect and compensate for the film position, product posture, and bonding angle in real time, resulting in a high defect rate such as misalignment and incorrect application; on the other hand, the working mode of picking up only one film at a time restricts the overall cycle time, limiting the room for improvement in production efficiency. In addition, most equipment is often designed for products of specific sizes or models, making it difficult to flexibly adapt to the production needs of multiple specifications and small batches, resulting in insufficient equipment versatility and increasing production line adjustment and hardware investment costs. Therefore, the industry urgently needs an automated film application equipment that is compact, has high application accuracy, is highly adaptable, and can significantly improve production efficiency, in order to solve the problems of unstable film quality, low efficiency, and limited applicability in existing technologies.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1-4As shown, this application discloses an automatic auxiliary material application equipment, including a machine base 1, a left and right conveyor belt 2 on the machine base 1, a film application mechanism 3 above the conveyor belt 2, a feeder 4 for providing auxiliary materials on the rear side of the conveyor belt 2, a position detection component 5 above the film application mechanism 3, a material detection component 7 between the conveyor belt 2 and the feeder 4, and a loading and unloading mechanism 6 above both the left and right ends of the conveyor belt 2.

[0024] The film application mechanism 3 includes a first support 31, on which a front-to-back translation drive 32 is provided. The front-to-back translation drive 32 is connected to a first linear module 34 for left-to-right transmission. A first linear guide rail 33 is provided between the first linear module 34 and the first support 31. The first linear module 34 is connected to a suction component 35 for handling and applying auxiliary materials.

[0025] In this application, the auxiliary material application equipment is used to apply film to the surface of products. A belt conveyor 2 transports the product left and right; an application mechanism 3 picks up, transports, and applies the film; a feeder 4 provides continuous and automatic film supply; a position detection component 5 detects the position of the product and the film, ensuring that the application mechanism 3 can accurately pick up and apply the film; an unloading mechanism 6 enables offline film application, eliminating the need for manual loading and unloading; and a material detection component 7 detects the orientation and type of film picked up by the application mechanism 3, ensuring accurate film application.

[0026] In this application, the film application mechanism 3 includes a first bracket 31, a front-to-back translation drive 32, a first linear guide rail 33, a first linear module 34, and a suction assembly 35. The first bracket 31 is used for mounting the various components. The front-to-back translation drive 32 drives the first linear module 34 and the suction assembly 35 to move synchronously back and forth, enabling the film to be picked up from the feeder 4 and then applied to the product on the conveyor belt 2. The first linear guide rail 33 guides the front-to-back translation of the first linear module 34, ensuring smooth front-to-back translation of the suction assembly 35. The first linear module 34 drives the suction assembly 35 to move left and right, enabling horizontal left-to-right movement during film picking and application. With the cooperation of the front-to-back translation drive 32 and the first linear module 34, movement can be achieved at any position on the same horizontal plane, ensuring accurate film picking and application.

[0027] In this application, the belt conveyor 2 consists of three consecutive motor and belt conveyor lines connected end to end. The belt of the middle belt conveyor 2 is an optical belt, and the ring formed by it has a surface light source inside, which can shine upward to illuminate the products conveyed to the belt conveyor 2. It works in conjunction with the position detection component 5 to achieve precise positioning of the products and ensure the film application accuracy of the products.

[0028] like Figure 5As shown, in one embodiment of this application, the suction assembly 35 includes a second bracket 351, on which two vertically arranged second linear guide rails 352 are provided. The sliders of the two second linear guide rails 352 are respectively connected to a vertically arranged hollow shaft 353. The lower ends of the two hollow shafts 353 are respectively connected to a suction nozzle 354. A lifting drive 355 for driving the two sliders to move in opposite directions is provided between the two second linear guide rails 352.

[0029] In this embodiment, the second support 351 consists of a vertical plate and a horizontal plate, forming a right-angled support. The second linear guide rail 352 guides the vertical movement of the hollow shaft 353, ensuring smooth vertical movement. A bearing is provided at the connection between the hollow shaft 353 and the second linear guide rail 352 to ensure that the hollow shaft 353 can rotate relative to the slider of the second linear guide rail 352. A suction nozzle 354 is connected to the lower end of the hollow shaft 353. The vertical movement of the hollow shaft 353 drives the suction nozzle 354 to move up and down synchronously. Simultaneously, the hollowness of the hollow shaft 353 serves as a ventilation channel for the suction nozzle 354. The lifting drive component 355 drives the slider of the second linear guide rail 352 to rise and fall, thereby driving the hollow shaft 353 to rise and fall synchronously.

[0030] In this embodiment, there are two second linear guide rails 352, hollow shafts 353, and suction nozzles 354, which can hold two films and transport two films at once, reducing the time spent transporting films back and forth and improving film application efficiency. The lifting drive component 355 consists of a motor, a belt, and pulleys. The two pulleys are arranged vertically. The motor drives the belt to move up and down, which in turn drives the two sliders of the two second linear guide rails 352 to move in opposite directions. This drives the two hollow shafts 353 to move synchronously in opposite directions, either from left to right or from left to right, to pick up two films and apply them one by one. The two actions alternate without interference. This allows for the application of one film, two films, or even multiple films, and there are no restrictions on the application position.

[0031] like Figure 5 and Figure 6As shown, furthermore, each of the two hollow shafts 353 is connected to a bearing seat 356, which is rotatably mounted on the second bracket 351. A rotary drive component 357 is connected between the two bearing seats 356 to drive their rotation. The rotatable arrangement of the bearing seats 356 on the second bracket 351 ensures that the bearing seats 356 can rotate relative to the second bracket 351, thereby driving the hollow shafts 353 to rotate, and consequently driving the suction nozzle 354 to rotate, thus rotating the adsorbed membrane. This allows the membrane to be rotated to a set angle before application. The rotary drive component 357 drives the bearing seats 356 to rotate, causing the hollow shafts 353 to rotate synchronously. The bearing seats 356 contain ball spline bushings 358, and the hollow shafts 353 have keyways 3531. Balls are positioned between the keyways 3531 and the ball spline bushings 358. The arrangement of the ball spline sleeve 358, keyway 3531, and balls ensures that the hollow shaft 353 can slide up and down relative to the ball spline sleeve 358, and the balls reduce the friction during sliding, ensuring smooth up and down movement of the hollow shaft 353 relative to the bearing housing 356. The ball spline sleeve 358 is fixedly connected to the bearing housing 356, ensuring that the bearing housing 356 can drive the ball spline sleeve 358 and the hollow shaft 353 to rotate synchronously when rotating, thereby driving the nozzle 354 to rotate.

[0032] Based on the above embodiments, the rotary drive component 357 further includes a motor, a drive pulley mounted on the motor output shaft, synchronous pulleys mounted at the lower ends of the two bearing seats 356, and a synchronous belt that transmits power between the drive pulley and the two synchronous pulleys. The rotation of the motor enables the synchronous belt to transmit power between the drive pulley and the two synchronous pulleys. The synchronous pulleys are fixedly connected to the bearing seats 356, thereby driving the bearing seats 356 to rotate relative to the second bracket 351, thus achieving the purpose of rotating the hollow shaft 353.

[0033] like Figure 4 As shown, in another embodiment of this application, the position detection component 5 includes a first detection camera 51 mounted above the front side of the suction component 35 and two second detection cameras 52 mounted above the suction component 35. A first light source 53 is provided below the first detection camera 51, and a second light source 54 is provided below each of the two second detection cameras 52. There are two feeder feeders 4, and the two second light sources 54 are respectively located below the feeding platforms of the two feeder feeders 4.

[0034] In this embodiment, the position detection component 5 includes a first detection camera 51 and a second detection camera 52 arranged front and rear. The first detection camera 51 is used to detect the position of the product, ensuring accurate film application. The second detection camera 52 is used to detect the position of the film on the feeder 4, ensuring that the suction nozzle 354 can accurately pick up the film. The first light source 53 provides sufficient brightness to the first detection camera 51, ensuring accurate product detection. Simultaneously, the surface light source located within the annular structure of the conveyor belt 2 further ensures the accuracy of the detected product position, improves film application quality, and effectively prevents inaccurate product position detection due to light source obstruction. The second light source 54 is located below the feeding platform of the feeder, providing sufficient illumination to ensure the imaging quality of the second detection camera 52 and accurate detection of the film on the feeding platform of the feeder 4.

[0035] In this embodiment, there are two feeders 4, which can effectively improve the handling efficiency and film application efficiency of the film and greatly reduce the film handling time.

[0036] like Figure 7 As shown, in another embodiment of this application, the loading and unloading mechanism 6 includes a second linear module 61 arranged in front and behind. The second linear module 61 is connected to a cylinder 62 arranged in front and behind. The lower end of the cylinder 62 is connected to a horizontally arranged mounting plate 63. A plurality of vacuum suction cups 64 are mounted on the mounting plate 63.

[0037] In this embodiment, the loading and unloading mechanism 6 is used for automatic loading and unloading of the adhesive applicator in offline mode. It can transport products from the product supply end to the conveyor belt 2 and remove the film-applied products from the conveyor belt 2. The second linear module 61 drives the cylinder 62, mounting plate 63, and vacuum suction cup 64 to move synchronously back and forth, realizing the transport of products. The cylinder 62 is used to drive the mounting plate 63 and vacuum suction cup 64 to rise and fall, realizing the adsorption and release of products. When the second linear module 61 drives the vacuum suction cup 64 to the product supply end, and then the cylinder 62 drives the vacuum suction cup 64 to fall, the vacuum suction cup 64 picks up the product, and then, with the cooperation of the cylinder 62 and the second linear module 61, the product can be transported to the conveyor belt 2. The product unloading operation is the same, except that the vacuum suction cup 64 picks up the film-applied product, and then, with the cooperation of the cylinder 62 and the second linear module 61, the product is lowered and transported out of the conveyor belt 2 and placed at the unloading station.

[0038] like Figure 8As shown, based on the above embodiment, the material detection component 7 includes two third detection cameras 71, which are respectively disposed in front of the two feeder feeders 4. A third light source 72 is provided above each of the two third detection cameras 71. The material detection component 7 is used to detect the placement angle of the film adsorbed on the nozzle 354. By comparing and detecting the detected film placement angle with the required adhesion angle, the film adsorbed on the nozzle 354 can be rotated to the required adhesion angle by the rotation drive 357 before the product is laminated, improving the adhesion quality. Specifically, by taking a picture of the film on the nozzle 354 from below using the third detection camera 71, it can be determined whether the film is at the adhesion angle. If it is, the film is laminated directly; otherwise, the rotation drive 357 rotates it to the adhesion angle. The third light source 72 provides light to the third detection camera 71, ensuring the detection accuracy of the third detection camera 71. Simultaneously, the third detection camera 71 is also used to detect whether there is a film on the nozzle 354, preventing empty or missed lamination.

[0039] In this application, the working process of the applicator is as follows: the product is transported to the conveyor belt 2 by the loading and unloading mechanism 6 located on the left side; the conveyor belt 2 stops transporting the product after it reaches the set position; at the same time, the feeder 4 supplies material, the film applicator 3 operates, and the forward and backward translation drive 32 and the first linear module 34 cooperate to move the suction assembly 35 to the feeding platform of the feeder 4; the lifting drive 355 of the suction assembly 35 drives the hollow shaft 353 and the suction nozzle 354 to descend and adsorb the film; then the suction assembly 35 moves to the material detection assembly. Above 7, the material detection component 7 detects the film placement angle, and the first detection camera 51 of the position detection component 5 detects the film application position of the product on the conveyor belt 2. It detects whether the film placement angle is consistent with the required application angle. If they are inconsistent, the hollow shaft 353 is driven to rotate by the rotary drive component 357 to adjust the film angle. Then, the film application mechanism 3 applies the film to the product to complete the product application. Finally, the conveyor belt 2 transports the film-applied product to the lower part of the loading and unloading mechanism 6 on the right side, and the film-applied product is transported out by the loading and unloading mechanism 6 at this position.
