Description

Technical Field

[0001] This utility model relates to the technical field of film and sheet production equipment, and in particular to a high-speed, neat material receiving mechanism for visual positioning of film products. Background Technology

[0002] In the production of precision thin film sheets such as polarizers and optical films, the neatness, non-destructive nature, and high efficiency of the receiving stage are crucial. Current technology often employs a swing-arm receiving mechanism, where the product swings to the top of the material box and then falls freely. This method has the following significant drawbacks:

[0003] First, the product is prone to collision and scratches with the mechanism during the fall, resulting in damage to the product surface or corners (machine damage);

[0004] Secondly, the free fall posture is uncontrollable, and the products stacked in the material box are prone to displacement due to static electricity, airflow and other factors, resulting in loose and uneven material collection, which affects subsequent automated processing.

[0005] Secondly, the equipment has poor compatibility. When changing product specifications, it is necessary to stop the machine to replace the material box and readjust it, which is inefficient.

[0006] Finally, the single-material box design requires the machine to be stopped and replaced after it is full, which makes continuous production impossible and creates a production capacity bottleneck.

[0007] Therefore, there is an urgent need for a material receiving mechanism that can achieve high-speed, neat, damage-free, and continuous production. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-speed neat film product visual positioning receiving mechanism that has a simple structure and can effectively improve the neatness of film product receiving.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a high-speed and neat film product visual positioning and receiving mechanism for neatly receiving film products, including a frame, wherein at least one receiving station is provided on the frame; the receiving station includes a conveying channel and a receiving component; a visual positioning camera for identifying the position and angle of the film products on the channel is provided above the conveying channel;

[0010] The receiving assembly includes a material box, which is mounted on the frame at an angle relative to the horizontal plane;

[0011] The receiving station also includes a four-axis gripping mechanism for transferring products between the conveying channel and the receiving component. The vision positioning camera is signal-connected to the four-axis gripping mechanism. The four-axis gripping mechanism includes a drive component that can move along the XYZ direction and rotate around the Z-axis. The output end of the drive component is provided with a suction cup assembly.

[0012] The conveyor channel is used to transport film products; the vision positioning system is used to identify the position and angle of the film products on the channel; the material box is used to receive and collect film products; the four-axis gripping mechanism controls the suction cup assembly to grip the film products according to the positioning information of the vision positioning system and transports the film products to the material box of the receiving assembly.

[0013] The aforementioned high-speed, neat film product visual positioning and collection mechanism achieves non-destructive, high-speed, and high-precision neat collection of film products through a systematic combination of visual positioning, four-axis precision handling, and tilting material box. This solves the fundamental problems of uneven collection and machine damage mentioned in the background technology.

[0014] Furthermore, the material box is mounted on the frame by four legs at its bottom, and the height of one of the legs is lower than that of the others, forming the lowest reference point of the inclined plane of the material box. The lowest side of the inclined plane constitutes the reference surface for product self-correction.

[0015] The four legs form a specific, stable, and easy-to-implement mechanical structure for the tilting of the material box. Its function is to ensure the accuracy and consistency of the tilting angle of the material box through machining, and the structure is simple and reliable. In addition, it ensures that the product can slide to the same side wall every time, which improves the stability and uniformity of the correction effect.

[0016] Furthermore, this high-speed, neat material receiving mechanism for visual positioning of thin film products also includes a material box base plate, which is mounted on the frame via a linear guide rail assembly, and the material box is mounted on the base plate. The linear guide rail assembly allows the base plate and the material box to slide in and out as a whole, facilitating quick replacement and maintenance of the material box and reducing downtime.

[0017] Furthermore, the driving component includes an X-axis linear module mounted on the frame, a Y-axis linear motor mounted at the output end of the X-axis linear module, a Z-axis lifting assembly mounted at the output end of the Y-axis linear motor, a motor base mounted at the output end of the Z-axis lifting assembly, a rotary motor mounted on the motor base, and a suction cup assembly mounted on the output end of the rotary motor; the suction cup assembly includes a suction cup base plate with the end of the rotary motor, and multiple vacuum suction cups are arrayed on the suction cup base plate.

[0018] The X-axis linear module, Y-axis linear motor, Z-axis lifting assembly, and rotary motor ensure accurate product positioning and rotation, reducing placement deviations from the outset. The Y-axis linear motor operates smoothly and is suitable for high-speed cycles. Furthermore, the arrayed vacuum suction cups provide a physical basis for compatibility with products of different sizes.

[0019] Furthermore, each vacuum suction cup has a corresponding logic valve installed at its air inlet. This structure enables independent control of the vacuum suction cups, selectively activating some suction cups based on product size to avoid over-adsorption or interference with small products, greatly enhancing the size compatibility of the equipment; it also improves the reliability and energy efficiency of product adsorption.

[0020] Furthermore, the material box is a PP material box, with four jig blocks at the bottom of the PP material box. The jig blocks are mounted on the bottom plate of the material box, and the top of the jig blocks has an inclined surface structure to tilt the PP material box. The upper surface of the PP material box has blocks around its perimeter to prevent the film product from slipping off. The PP material box is detachably mounted on the jig blocks.

[0021] Furthermore, the material box is a sheet metal material box, with four supporting feet at the bottom. The supporting feet are mounted on the bottom plate of the material box, and the top of the supporting feet has an inclined structure to allow the sheet metal material box to tilt. The upper surface of the sheet metal material box has a retaining edge to prevent the film product from slipping off. The sheet metal material box is detachably mounted on the supporting feet, and the supporting feet are height-adjustable.

[0022] Furthermore, this high-speed, neat material receiving mechanism for visual positioning of film products also includes a cleaning box assembly, the inlet of which is connected to the outlet of the conveying channel; the cleaning box assembly includes a box body, four feet at the bottom of the box body are provided with cleaning box support feet, and the top of the cleaning box support feet is provided with an inclined surface structure to achieve tilting of the box body; the upper surface of the box body is provided with a cleaning box guard to prevent the film products from slipping.

[0023] Furthermore, the height of one of the cleaning box support legs in the cleaning box assembly is lower than that of the other support legs, forming the lowest reference point of the box body.

[0024] In the event of equipment failure or debugging, the system can automatically guide online products into the cleaning box assembly to prevent product accumulation and damage and equipment jamming, thereby reducing maintenance costs and risks. The cleaning box assembly also adopts a tilting self-correcting structure to ensure the orderly stacking of products during the cleaning process, which facilitates subsequent processing.

[0025] Furthermore, the bottom plate of the material box is provided with a handle on its side for easy pulling. The handle greatly facilitates the operator in pulling and moving the heavy bottom plate of the material box, reducing labor intensity and improving the efficiency and safety of material changing operations.

[0026] The beneficial effects of this utility model are: this utility model is reasonably designed and easy to operate, and has the following advantages:

[0027] (1) High yield: The suction cup assembly uses negative pressure to adsorb the product, while the four-axis gripping mechanism accurately positions and transports it. The two work together to unload the product, accurately avoiding all product contact surfaces. The product is placed smoothly into the material box, breaking the negative pressure and completely eliminating hard collisions and friction, making the product less prone to damage.

[0028] (2) High uniformity: When the product falls, the visual positioning camera guides the data to automatically correct the product position. The four-axis gripping mechanism grabs the product as close as possible to the receiving box to eliminate the air pressure gap between the sheets. The material box is placed at an angle. After the product falls in, the slight misalignment is corrected to ensure the neatness and compactness of the stack.

[0029] (3) High flexibility: This utility model can quickly switch between PP material box and sheet metal material box, and is compatible with products of different sizes (product size range 11 to 24.5 inches), adapting to the needs of flexible and automated production;

[0030] (4) High efficiency: The "dual-station unloading + four-box material collection" is adopted. The rapid positioning and switching of multiple boxes realizes continuous production, greatly reduces downtime, and significantly increases production capacity (up to 1300pcs / h or more).

[0031] (5) High automation: The entire process requires no manual intervention and has an automatic fault clearing function, which reduces labor costs and operational difficulty. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] like Figures 1 to 7The diagram illustrates a high-speed, neatly arranged film product visual positioning mechanism for neatly collecting film products 6. It includes a frame 1 with two collection stations. Each collection station includes a conveyor channel 2 and a collection assembly 5. A visual positioning camera 3 is positioned above the conveyor channel 2 to identify the position and angle of the film products on the channel. The collection assembly 5 includes two material boxes 51, which are mounted on the frame 1 at an angle relative to the horizontal plane. Each collection station also includes a four-axis gripping mechanism 4 for transferring products between the conveyor channel 2 and the collection assembly 5. The visual positioning camera 3 and the four-axis gripping mechanism 4 are signal-connected. The four-axis gripping mechanism 4 includes a drive component that can move along the XYZ directions and rotate around the Z-axis. A suction cup assembly 41 is provided at the output end of the drive component. Two material boxes 51, one for primary use and the other for backup, are used alternately for material collection during the material collection process to increase material collection capacity. When the material box 51 at the current material collection position is about to be full, the system issues an early warning and the four-axis material gripping mechanism 4 quickly moves to another empty material box station to continue material collection, thereby achieving continuous production and increasing capacity.

[0045] This high-speed, neat material receiving mechanism for visual positioning of thin film products also includes a central controller that controls the operation of the entire mechanism.

[0046] The conveying channel 2 includes four parallel wide belts 21, which are driven by a belt drive device.

[0047] The conveyor channel 2 is used to transport film products; the vision positioning camera 3 is used to identify the position and angle of the film products on the channel; the material box 51 is used to receive and accept film products; the four-axis gripping mechanism 4 controls the suction cup assembly 41 to grip the film products according to the positioning information of the vision positioning system 3, and transports the film products to the material box 51 of the receiving assembly 5.

[0048] The aforementioned high-speed, neat film product visual positioning and collection mechanism achieves non-destructive, high-speed, and high-precision neat collection of film products through a systematic combination of visual positioning, four-axis precision handling, and tilting material box. This solves the fundamental problems of uneven collection and machine damage mentioned in the background technology.

[0049] The material box 51 is mounted on the frame 1 by four legs at its bottom, with one leg being lower than the others, forming the lowest reference point of the inclined plane of the material box 51. The lowest side of this inclined plane constitutes the reference plane for product self-correction. In other words, among the four corners of the material box 51, there is one corner with the lowest position.

[0050] The four legs form the tilted setting of the material box 51, which is a specific, stable and easy-to-implement mechanical structure. Its function is to ensure the accuracy and consistency of the tilt angle of the material box 51 through machining, and the structure is simple and reliable. In addition, it ensures that the product can slide to the same side wall every time, which improves the stability and uniformity of the correction effect ≤±1mm.

[0051] This high-speed, neat material receiving mechanism for visual positioning of thin film products also includes a material box base plate 8, which is mounted on the frame 1 via a linear guide rail assembly. The material box 51 is mounted on the material box base plate 8. The linear guide rail assembly allows the material box base plate 8 and the material box 51 to slide in and out as a whole, facilitating quick replacement and maintenance of the material box 51 and reducing downtime.

[0052] The driving components include an X-axis linear module 42 mounted on the frame 1, a Y-axis linear motor 43 mounted on the output end of the X-axis linear module 42, a Z-axis lifting assembly 44 mounted on the output end of the Y-axis linear motor 43, a motor base 45 mounted on the output end of the Z-axis lifting assembly 44, a rotary motor 46 mounted on the motor base 45, and a suction cup assembly 41 mounted on the output end of the rotary motor 46. The suction cup assembly 41 includes a suction cup base plate 47 with the end of the rotary motor 46, and multiple vacuum suction cups 48 are arrayed on the suction cup base plate 47.

[0053] The X-axis linear module 42, Y-axis linear motor 43, Z-axis lifting assembly 44, and rotary motor 46 ensure the accuracy of product positioning and rotation, reducing placement deviations from the outset. The Y-axis linear motor 43 operates smoothly and is suitable for high-speed cycles. In addition, the arrayed vacuum suction cups 48 provide a physical basis for compatibility with products of different sizes.

[0054] Each vacuum suction cup 48 has a corresponding logic valve installed at its air inlet (not shown in the figure). This structure enables independent control of the vacuum suction cup 48, selectively opening some suction cups according to the product size, avoiding excessive adsorption or interference with small products, greatly enhancing the size compatibility of the equipment (11-24.5 inches); at the same time, it improves the reliability and energy efficiency of product adsorption.

[0055] Material box 51 is a PP material box 52. The bottom of the PP material box 52 has four jig blocks 54. The jig blocks 54 are mounted on the bottom plate 8 of the material box. The top of the jig blocks 54 has a sloping structure to make the PP material box 52 tilt. The upper surface of the PP material box 52 has blocks 53 around its perimeter to prevent the film product 6 from slipping off. The PP material box 52 is detachably mounted on the jig blocks 54.

[0056] The material box 51 is a sheet metal material box 55. The bottom of the sheet metal material box 55 has four support feet 57, which are mounted on the bottom plate 8 of the material box. The top of the support feet 57 has a sloping structure to allow the sheet metal material box 55 to tilt. The upper surface of the sheet metal material box 55 has a retaining edge 56 to prevent the film product 6 from slipping off. The sheet metal material box 55 is detachably mounted on the support feet 57, and the support feet 57 are height-adjustable.

[0057] For large-sized products with a size of 24.5 inches, PP material box 52 is used for receiving materials; for small-sized products, sheet metal material box 55 of the corresponding size is used for receiving materials.

[0058] This high-speed, neat material receiving mechanism for visual positioning of film products also includes a cleaning box assembly 7. The inlet of the cleaning box assembly 7 is connected to the outlet of the conveying channel 2. The cleaning box assembly 7 includes a box body 71. The bottom of the box body 71 has four cleaning box support legs 72. The top of the cleaning box support legs 72 has a sloping structure that allows the box body 71 to tilt. The upper surface of the box body 71 has a cleaning box guard edge 73 to prevent the film product 6 from slipping. The height of one of the cleaning box support legs 72 of the cleaning box assembly 7 is lower than that of the other support legs, forming the lowest reference point of the box body 71.

[0059] In the event of equipment failure or debugging, the online products can be automatically imported into the cleaning box assembly 7 to prevent product accumulation and damage and equipment jamming, thereby reducing maintenance costs and risks. The cleaning box assembly 7 also adopts a tilting self-correcting structure to ensure the orderly stacking of products during the cleaning process, which facilitates subsequent processing.

[0060] The bottom plate 8 of the material box has a handle on its side for easy pulling (not shown in the figure). The handle greatly facilitates the operator in pulling and moving the heavy bottom plate 8 of the material box, reducing labor intensity and improving the efficiency and safety of material changing operations.

[0061] The working process of this high-speed, neat material collection mechanism for visual positioning of thin film products is as follows:

[0062] (1) The conveyor channel 2 transports the film product 6 to the area directly below the visual positioning camera 3, the conveyor channel 2 stops, and the visual positioning camera 3 takes a picture of the film product 6.

[0063] (2) The visual positioning camera 3 takes positioning photos and outputs the product's coordinates and angle position, which are then transmitted to the four-axis gripping mechanism 4 via signal.

[0064] (3) The four-axis gripping mechanism 4 moves the suction cup assembly 41 to the center of the film product 6 according to the coordinate position and product angle given by the vision positioning camera 3.

[0065] (4) The suction cup assembly 41 adsorbs the film product 6 and moves it upward. This step can be carried out by selecting different corresponding suction cups according to the size of each batch of film, so as to achieve corresponding formula control.

[0066] (5) During the rapid transport process of the Y-axis linear motor 43, the rotary motor 46 performs rotational correction according to the product angle.

[0067] (6) The four-axis gripping mechanism 4 moves the corrected film product 6 to the tilted material box 51. The film product 6 is located 10mm above the material box 51. After the suction cup assembly 41 breaks the vacuum, it releases the product and makes the product fall into the material box (51) to complete the material collection.

[0068] (7) The four-axis material gripping mechanism 4 returns to its initial position and waits for the next product.

[0069] During the falling process of film product 6, the air pressure gap between the sheets can be eliminated. In addition, the material box 51 is placed at an angle, and after the product falls in, it corrects the slight misalignment and automatically sticks to the low side wall of the material box 51 under the action of gravity, ensuring the neatness and compactness of the material stack.

[0070] In summary, this utility model has a simple structure and achieves precise positioning of products through a four-axis gripping mechanism 4 and a vision positioning camera 3, breaking the conventional swing arm material collection method in the film and sheet industry. Specifically, the four-axis gripping mechanism 4, in conjunction with the start and stop of the conveyor channel 2 and the coordinates provided by the vision positioning camera 3, enables the product to be accurately adsorbed and transported by the suction cup assembly 41 without deviation. At the same time, it can effectively compensate for the angle and position of the product during the unloading process, solving the problems of uneven material collection and machine damage.

[0071] The wide flow channel and multiple suction cups enable the transfer and gripping of materials of different sizes, providing wide compatibility. The material box 51 is set at an angle and can be used with different fixture blocks to switch between PP material box 52 and sheet metal material box 55, realizing multiple material box receiving modes.

[0072] The four-axis material handling mechanism 4 is equipped with a Y-axis linear motor 43, which has a fast operating speed and high production capacity.

[0073] To prevent product damage caused by equipment downtime, a cleaning function has been added. In case of equipment failure, the product will automatically flow to the final cleaning box assembly 7.

[0074] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the description without departing from the essence and scope of the utility model.
