Description

Technical Field

[0001] This invention relates to the field of sheet transfer equipment technology, and in particular to a sheet handling and transfer device and its control method. Background Technology

[0002] The process involves placing multiple cut flat blanks into a hot molding die for hot molding. However, because the flat blanks are directly transported to the hot molding die using a transfer trolley, the seams between the blanks can shift during the trolley's movement. When the suction cups adhere the entire blank to the hot molding equipment, it can lead to asymmetrical fiber structure within the molded workpiece, resulting in the workpiece's performance failing to meet usage requirements. Summary of the Invention

[0010] The linear module extends along a sliding direction perpendicular to the transfer trolley, the vacuum suction cup assembly transports the sheet material on the transfer trolley to the transfer platform, and the first limiting assembly and two second limiting assemblies precisely position the sheet material.

[0011] Furthermore, the transfer trolley is provided with a scribing area for placing the material sheet.

[0012] Furthermore, the transfer platform is equipped with a mobile gantry frame, and a laser marking machine is installed on the mobile gantry frame;

[0013] The moving gantry frame drives the laser marking machine to move along the length of the material sheet to spray a reference line on the central axis of the material sheet.

[0014] Furthermore, the transfer trolley is equipped with a scanner that works in conjunction with the barcode on the material sheet;

[0015] Furthermore, the laser projector projects the contour trajectory line corresponding to the material sheet onto the bearing surface of the transfer trolley.

[0023] Furthermore, the support base is fixedly mounted on the transfer platform, and the support base includes two symmetrically arranged support blocks, with the first limiting component disposed between the two support blocks;

[0024] The first limiting component includes a movable seat, a driving component for driving the movable seat to move along the X direction, a cylinder disposed on the movable seat, and a stop block disposed on the driving end of the cylinder.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] like Figures 1 to 9 The sheet handling and transfer device shown includes: a transfer truss 1, a transfer trolley 2, a laser projector 3, and a handling assembly 4; the transfer truss 1 is arranged side by side on one side of the hot molding equipment; the transfer trolley 2 is used to carry the cut sheet and move along the running track from the cutting machine to the material picking position of the hot molding equipment; multiple laser projectors 3 are arranged along the length of the transfer truss 1 to perform initial positioning of the sheet on the transfer trolley 2; the handling assembly 4 is arranged on the transfer truss 1 and includes multiple linear modules 41 arranged on the transfer truss 1, a screw jack 42 located on the same side of the drive end of the multiple linear modules 41, and a vacuum suction cup assembly 43 arranged on the drive end of the screw jack 42, for handling the sheet on the transfer trolley 2;

[0052] Among them, a transfer platform 5 is set in the arched space erected by the transfer truss 1, and the transfer platform 5 is provided with a support seat 6 for supporting the material piece, a first limiting component 7 for limiting the material piece in the X direction, and two second limiting components 8 for limiting the material piece in the Y direction.

[0053] The linear module 41 extends along a sliding direction perpendicular to the transfer trolley 2, and the vacuum suction cup assembly 43 transports the sheet material on the transfer trolley 2 to the transfer platform 5. The first limiting assembly 7 and two second limiting assemblies 8 precisely position the sheet material. It should be noted that the X direction refers to the length direction of the sheet material, while the Y direction refers to the width direction of the sheet material.

[0054] This invention achieves automatic handling and positioning of sheet metal by setting up a transfer trolley 2, a linear module 41, a screw jack 42, and a vacuum suction cup assembly 43, which greatly improves production efficiency. Based on the initial positioning of the laser projector 3, the support base 6 on the transfer platform 5, the first limiting assembly 7, and the second limiting assembly 8 together form a precision positioning system, which can ensure the precise position of the sheet metal in the X and Y directions, ensuring the accuracy of the sheet metal's position during handling and improving product quality.

[0055] In a preferred embodiment of the present invention, the transfer trolley 2 is provided with a scribed area 2a for placing the material sheet. The scribed area 2a provides a clear reference frame for the material sheet, which facilitates the determination of the initial placement position of the material sheet, helps to reduce the positional deviation of the material sheet during handling and transfer, and ensures that the material sheet can be accurately transported to the target position.

[0056] In a preferred embodiment of the present invention, a movable gantry 9 is provided on the transfer platform 5, and a laser marking machine 10 is provided on the movable gantry 9; the movable gantry 9 drives the laser marking machine 10 to move along the length of the material sheet to spray a reference line on the central axis of the material sheet. The existence of the reference line provides a clear reference for subsequent processing, inspection or alignment steps, which helps to improve the overall production accuracy and consistency.

[0057] In another preferred embodiment, the transfer trolley 2 is equipped with a scanner that works in conjunction with the barcode on the material sheet. The scanner can quickly and accurately read the barcode information on the material sheet, thereby enabling rapid identification and verification of the material sheet, reducing the time spent manually searching and verifying the material sheet, and improving production efficiency. In addition, the laser projector 3 projects the contour trajectory line corresponding to the material sheet onto the bearing surface of the transfer trolley 2. Operators can quickly and accurately verify the preset material sheet sequence and specifications based on the contour trajectory line and perform preliminary positioning.

[0058] The preferred structure of the linear module 41 of the present invention is as follows: the linear module 41 includes a first telescopic arm 411 and a second telescopic arm 412 arranged in parallel, and a third telescopic arm 413 is provided between the first telescopic arm 411 and the second telescopic arm 412; the first telescopic arm 411 is fixed on the transfer truss 1, the third telescopic arm 413 is slidably disposed below the first telescopic arm 411 along its length direction, the second telescopic arm 412 is slidably disposed below the third telescopic arm 413, and the screw jack 42 is slidably disposed below the second telescopic arm 412 through a mounting base.

[0059] Specifically, the first telescopic arm 411, the second telescopic arm 412 and the third telescopic arm 413 form a three-level transmission mode to control the reciprocating motion of the vacuum suction cup assembly 43 to achieve a repeatability positioning accuracy of 0.05mm, thereby ensuring the centering accuracy of the vacuum suction cup assembly 43.

[0060] In this invention, the linear module 41 drives the vacuum suction cup assembly 43 to move horizontally to accurately reach the material position and realize the material handling. However, since the multiple linear modules 41 are independently controlled, in order to ensure that the multiple vacuum suction cup assemblies 43 reach the set adsorption position of the material synchronously, preferably, the driving end of the multiple linear modules 41 is provided with a transmission shaft 44, and the multiple vacuum suction cup assemblies 43 are arranged along the length direction of the transmission shaft 44; and a support frame 45 is provided on the transmission shaft 44 to support and drive the vacuum suction cup assembly 43 to move along the axial direction of the transmission shaft 44, and a linear drive member 46 to drive the support frame 45 to move.

[0061] The linear drive 46 drives the support frame 45 to move, adjusting the spacing between adjacent suction cups to accommodate the handling of sheets of different lengths.

[0062] As a preferred embodiment of the above, the linear drive 46 includes a servo motor and meshing gears and racks; the linear drive 46 is disposed on the right side of the support frame 45, the vacuum suction cup assembly 43 is disposed on the left side of the support frame 45, and a guide rail assembly is provided between the support frame 45 and the drive shaft 44; the rack is fixed on the side of the drive shaft 44 facing the support frame 45, and the gear is fixed on the drive end of the servo motor.

[0063] There are 17 suction cups per meter. Each suction cup is controlled by a stepper motor and can move within 1 meter in the X-axis direction, accurately moving to the designated position to adapt to materials of different sizes and shapes, thereby achieving precise gripping and placement of materials. In addition, the structural design of the support frame 45 and the drive shaft 44 makes the entire structure modular, which is easy to disassemble and replace.

[0064] In this invention, the support base 6 is fixedly mounted on the transfer platform 5. Since the prepreg sheet has a certain degree of flexibility, the support base 6 includes two symmetrically arranged support blocks, and the first limiting component 7 is disposed between the two support blocks. This increases the support area and can effectively disperse the pressure when the sheet is placed, preventing the middle position of the sheet from collapsing due to concentrated force. In addition, in the preferred structure, the first limiting component 7 includes a movable base 71, a driving component 72 for driving the movable base 71 to move in the X direction, a cylinder 73 disposed on the movable base 71, and a stop block 74 disposed at the driving end of the cylinder 73. When the driving component 72 drives the movable base 71 to slide the cylinder 73 to a designated position, the cylinder 73 drives the stop block 74 to move toward the sheet to limit the sheet in the X direction. This can accurately limit the sheet in the X direction and achieve stable limiting of the sheet.

[0065] In a preferred embodiment of the present invention, the second limiting component 8 includes a base 81, a support column 82 slidably disposed on the base 81, and a calibration block 83 disposed on the support column 82; the two calibration blocks 83 are disposed opposite to each other, and a receiving plane 83a and a guide slope 83b at an angle to the receiving plane 83a are provided on the contact surface between the calibration block 83 and the material sheet; the receiving plane 83a provided on the calibration block 83 can stably support the material sheet, avoiding positional deviation of the material sheet due to shaking or sliding during placement; when the guide slope 83b contacts the material sheet, it can gradually guide the material sheet to move to the correct position, avoiding damage to the material sheet due to sudden force; the combined design of the receiving plane 83a and the guide slope 83b enables the material sheet to move smoothly to the correct position when subjected to calibration force. After the sheet is placed on the support 6, the two pillars 82 move toward each other. The guide slope 83b calibrates the two edges of the sheet to limit the sheet in the Y direction, which can ensure that the sheet is accurately limited in the Y direction and avoid subsequent processing or assembly problems caused by positional deviation.

[0066] The present invention also provides a material sheet handling and transfer control method, applied to a material sheet handling and transfer device, comprising the following steps:

[0067] The cutting machine can cut materials into various specifications according to different cutting requirements;

[0068] The cut pieces are placed on the transfer trolley 2 in the preset piece order and move along the running track from the cutting machine to the material picking position of the hot molding equipment;

[0069] Once the transfer trolley 2 reaches the designated position, the laser projector 3 is activated to perform initial positioning of the material sheet on the transfer trolley 2.

[0070] After the initial positioning is completed, multiple linear modules 41 move synchronously, extending along the sliding direction perpendicular to the transfer trolley 2, and using the vacuum suction cup assembly 43 to pick up the material sheet from the transfer trolley 2 and transport it to the transfer platform 5.

[0071] The support seat 6 on the transfer platform 5 supports the material sheet, while the first limiting component 7 and the second limiting component 8 precisely position the material sheet to ensure its accurate position in the X and Y directions.

[0072] After precise positioning, the material sheet is transported to the hot molding equipment for hot molding processing.

[0073] This sheet material handling and transfer device boasts advantages such as high efficiency and automation, precise positioning, flexibility and scalability, as well as safety and reliability. During operation, it enables rapid and accurate handling and positioning of sheets, providing strong support for subsequent processing.

[0074] Those skilled in the art should understand that this invention is not limited to the above embodiments.
