Description

Technical Field

[0001] This utility model relates to the field of laser cutting tools technology, and in particular to a cutting and blanking device for processing heavy truck protective brackets. Background Technology

[0002] This utility model relates to the field of laser cutting tool technology, and in particular to a cutting and blanking device for processing heavy truck protective brackets. Cutting and blanking is a key process in the processing of heavy truck protective brackets, and its accuracy and efficiency directly affect the subsequent assembly and performance of the protective bracket. However, existing cutting and blanking devices for heavy truck protective brackets still have many shortcomings and cannot meet the requirements of efficient and high-precision processing. First, existing devices largely rely on manual positioning of materials. When materials are manually held or secured, operational errors can easily cause positional shifts, making it difficult to guarantee the alignment accuracy between the laser cutter and the material. Repeated calibrations are often necessary to ensure accurate cutting, extending preparation time and increasing manual labor intensity. Second, during the cutting process, existing devices use relatively fixed clamping methods. Either the material is completely fixed, restricting movement and rotation, limiting the cutting point to a single plane or fixed area, failing to meet the multi-space cutting requirements of complex protective bracket structures, or the clamping stability is insufficient, requiring manual intervention for unloading the protective bracket after cutting. Manual unloading not only increases labor costs but also reduces overall processing efficiency due to limited manual speed, making it difficult to adapt to the large-scale production needs of heavy-duty truck protective brackets. Therefore, these problems need to be addressed. Utility Model Content

[0005] Preferably, a sealing groove is provided horizontally at the front end of the top of the cutting chamber, and the sealing groove communicates with the inner cavity of the drive chamber. A vertical partition plate is installed on one side of the inner cavity of the drive chamber, and the partition plate divides the drive chamber into a drive chamber on one side and a winding chamber on the other side. A first servo motor is installed in the drive chamber, and the output shaft of the first servo motor passes through the partition plate and is placed in the winding chamber.

[0007] Preferably, the material feeding and conveying assembly includes support blocks horizontally installed at the front and rear ends of the inner bottom of the top plate. A first rotating roller is rotatably connected between the two support blocks on one side, and a second rotating roller is rotatably connected between the two support blocks on the other side.

[0008] Preferably, a sliding groove penetrating the support blocks is laterally formed above the adjacent end faces of the two support blocks. The sliding groove is located above the conveyor belt, and a positioning groove is formed on the top surface of the sliding groove.

High-precision cutting can be completed without repeated calibration, shortening preparation time. Furthermore, during the cutting process, the robotic arm stably holds the material, providing the protective bracket with space for movement and rotation outside the robotic arm's dead zones, further ensuring the multi-space capability of the cutting points. After cutting, the robotic arm directly completes the unloading operation, eliminating the need for manual intervention in the cutting and unloading processes, significantly reducing labor costs and improving overall processing efficiency. This utility model device achieves stable material conveying and cutting environment protection through the cooperation of the feeding and unloading conveying components and the cutting component. The feeding and conveying components uniformly convey the raw material to be cut into the cutting chamber, and the cooperation between the support block and the conveyor belt ensures the offset distance during the material conveying process. The cleaning table, together with the conveyor belt, transports the cutting residue away after cutting. During cutting, the stepper motor drives the rotating rod to extend and retract the sealing cloth, which, together with the sealing groove, achieves the sealing of the cutting chamber. The suction table quickly absorbs the smoke and dust generated during cutting through the connecting pipe, preventing the smoke and dust from overflowing and polluting the environment or adhering to the laser cutter and robotic arm, affecting the performance of the components, extending the service life of the core components, and ensuring the stability of subsequent cutting.

A conveyor belt 21 is sleeved between the second rotating roller and the first rotating roller, facilitating the supply of feed to the conveyor plate assembly. The support block 20, in conjunction with the cleaning table 18, can transport the cut waste material out within the feeding and conveying assembly. A first laser sensor 23 is installed on one side of the front end of the support block 20 to facilitate the initial positioning detection; the first laser sensor 23 is model HG-C1050L. A second laser sensor 24 is installed on the other side of the front end of the support block 20 to facilitate the verification of the detection count by the first laser sensor 23; the second laser sensor 24 is model HG-C1050L. A horizontal sliding groove penetrating the support block 20 is formed above the adjacent end faces of the two support blocks 20. The sliding groove is located above the conveyor belt 21, and a positioning groove is formed on the top surface of the sliding groove, in which a [missing information - likely a device or component] is installed. A metal plate 25 with an inverted U-shaped cross-section is used to facilitate subsequent energization and adhesion of the protective bracket to the transmission plate assembly, preventing damage to the protective bracket. A positioning plate 26, which slidably connects to the metal plate 25, is slidably connected between two sliding grooves.

A coil 28 is wound around the outside of the support column 27, which facilitates the connection between the support column 27, the positioning plate 26, and the... The metal plate 25 forms the principle structure of an electromagnet; the positioning plate 26, the support column 27 and the coil 28 together form a transmission plate assembly. The rear end of the cutting chamber 1 is equipped with a horizontally installed feeding transmission assembly in conjunction with the connecting groove 4.

The feeding transmission assembly is installed in proportion to the cutting chamber 1, and the front and rear ends of the bottom of the cutting chamber 1 are equipped with cleaning tables 18 with similar surfaces abutting the feeding transmission assembly. The cleaning table 18 facilitates the guidance of the component after the limit cut to slide onto the transmission belt 21 of the feeding transmission assembly. A robot arm 19 is installed in the middle of the front end of the bottom of the cutting chamber 1. The robot arm 19 facilitates the clamping of the protective bracket and drives the protective bracket to rotate in the non-dead space, thereby improving the cutting angle and orientation.

[0016] Working principle: When using this utility model, the transmission plate assembly is placed in a special external placement machine for the transmission plate assembly, the external suction pipe of the suction platform 5 is connected to the external suction system, and then the device is powered on. After the equipment is powered on, the second servo motor 22 inside the loading and unloading conveyor components is started, and the metal plate 25 inside the loading and unloading conveyor components is powered on. The second servo motor 22 drives the first transmission roller, which in turn drives the conveyor belt 21 to rotate. The operation of the loading and unloading conveyor components is checked. After the check is completed, the second servo motor 22 of the unloading conveyor component is turned off. At the same time, the placement machine installed on the outside of the loading and unloading conveyor components ejects the conveyor plate assembly. The second laser sensor 24 will detect whether the corresponding conveyor plate assembly is in place. At this time, the loading device installed on the outside of the loading conveyor component transports the roughly formed protective bracket into the conveyor belt 21 of the loading conveyor component. On the transmission plate assembly, support column 27 supports the protective bracket. Metal plate 25 and positioning plate 26 transmit external electrical energy to coil 28. At this time, coil 28 and support column 27 form an electromagnet structure to fix the protective bracket located on support column 27. When the transmission plate assembly on the feeding transmission assembly passes the first laser sensor 23, the power supply to the metal plate 25 of the feeding transmission assembly is turned off, and the support column 27 releases its attraction to the protective bracket. At this time, the first laser sensor 23 also serves to remind the cutting assembly that the item has reached the correct position. At the same time as releasing the attraction to the protective bracket, the second servo motor 22 of the feeding transmission assembly is turned off. The vision camera 17 installed on the connecting plate 15 will take pictures to position the protective bracket in conjunction with external control. The system initiates the operation by activating the robotic arm 19 to clamp the protective bracket. The robotic arm 19 then moves the protective bracket to the center of the top surface of the cleaning table 18. Subsequently, the suction table 5 is opened, and the first linear motor 11 and the second linear motor 12 are activated, driving the third linear motor 13 to the center of the cutting chamber 1. The vision camera 17 then takes a second photograph. After the second photograph is completed, the laser cutter 16, installed in the fixed platform 14, is activated to cut at the position specified in the process requirements. The robotic arm 19 also coordinates with the laser cutter 16 to change the position of the protective bracket (each position change requires a photograph from the vision camera 17). After the protective bracket is cut, the second servo motor 22 of the feeding and conveying assembly is activated to remove the cut waste. Simultaneously, the drive chamber 3, separated by a partition... The first servo motor 8, which is installed separately in the drive chamber, drives the rotating rod 9 to rotate, thereby lifting the sealing cloth 10 limited by the sealing groove 6. At the same time as the first servo motor 8 starts, the second servo motor 22 of the unloading and conveying assembly will also start simultaneously. With the offset code return data of the first servo motor 8, the conveying plate assembly will move to the middle of the unloading and conveying assembly. Then, the robot arm 19 will place the cut protective bracket on the top surface of the conveying plate assembly on the unloading and conveying assembly. The first laser sensor 23 installed on the unloading and conveying assembly will detect whether the protective bracket is being transported and transmit the data to the control system. Then, the first servo motor 8 will cover the sealing cloth 10 for the next cut. The above process can be used.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
