Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to automatic loading and unloading equipment for hot pressing of fireproof boards. Background Art

[0002] At present, there are many ways to process boards, which vary depending on different needs. Calendering or engraving fine lines on the surface of the board is a kind of fine processing for the board. This processing is used in places such as floors that require high surface quality and shape accuracy.

[0003] A common way to process patterns is hot pressing, which generally involves stacking patterned steel plates with plates, allowing the patterned side of the steel plate to contact the plate, and then hot pressing to press the pattern of the steel plate onto the plate. Therefore, it involves the loading and unloading of steel plates and plates, and how to realize the automation process of loading and unloading.

[0004] In addition, the quality of the pattern hot-pressed on the plate is also closely related to the cleanliness of the steel plate and the conveying platform for conveying the steel plate and the template. Because the steel plate and the conveying platform are always in the recycling process, there will be dust and impurities on their surface. Therefore, in order to ensure the quality of the pattern of the final pressed plate, the cleanliness of the conveying platform and the steel plate used for pressing must be ensured during loading.

[0005] The purpose of the present invention is to study a loading and unloading device that can achieve the above purpose. Summary of the invention

[0008] The end of the robot arm is provided with a grasping mechanism for grasping the steel plate, the grasping mechanism comprises a mounting plate, a mounting frame and a plurality of vacuum suction cups mounted on the mounting frame, the mounting plate is directly mounted on the end of the robot arm, the middle position of the mounting frame is fixedly mounted on the mounting plate, the vacuum suction cups are arranged on the mounting frame at intervals, and the distance between adjacent vacuum suction cups is 810-830 mm;

[0009] The unloading station is provided with a conveying mechanism, through which the conveying tray located at the unloading station is conveyed to the transfer station, and the loading station is also provided with a conveying mechanism, through which the conveying tray, fireproof board and steel plate are conveyed to the subsequent process, and the transfer station is also provided with a conveying mechanism for transporting the conveying tray;

[0010] The steel plate is transported from the unloading station to the loading station by the mechanical arm;

[0011] The cleaning mechanism includes a cleaning brush and a static elimination rod;

[0012] The cleaning brush is installed on the mounting frame. The cleaning brush is a long strip brush. The length of the cleaning brush is consistent with the length of the loading station. The thickness of the cleaning brush is 1-2 cm. In the vertical plane, the lower end of the bristles of the cleaning brush extends 4-5 mm from the gripping mechanism.

[0013] The static elimination bar is installed at the edge of the loading station and / or the edge of the unloading station. The static elimination bar is lower than the working surface of the loading station and / or the unloading station in the vertical plane, and static dust removal is performed when the conveying carrier passes through the static elimination bar.

[0014] Furthermore, the bristles of the cleaning brush are nylon filaments with a diameter of 0.76 mm, which are bonded at the roots of the bristles to form bristle clusters with a diameter of 25 mm.

[0015] Furthermore, the static elimination bar is a static elimination bar of model AS-6300BF produced by Shanghai Enshuo Electronic Technology Co., Ltd.

[0016] Furthermore, the mounting frame includes a transverse connecting rod and a longitudinal connecting rod, the transverse connecting rods are arranged at intervals along the length direction of the longitudinal connecting rod, and each end of the transverse connecting rod is fixedly connected to the longitudinal connecting rod, and the vacuum suction cup is located at the connection between the transverse connecting rod and the longitudinal connecting rod.

[0017] Furthermore, the robotic arm is a robotic arm that can rotate arbitrarily in three-dimensional space.

[0020] Furthermore, the conveying mechanism is a motor-driven sprocket chain transmission mechanism.

[0021] Furthermore, the thickness of the steel plate is 2-5 mm, and the depth of the pattern is 0.1-0.2 mm.

[0022] Furthermore, when the vacuum suction cup is in a negative pressure state, the vacuum suction cup absorbs the material to be grasped; when the vacuum suction cup blows air outward, the vacuum suction cup blows away dust.

[0023] The beneficial effects of the present invention are:

[0024] The present invention comprises a mechanical arm, a loading station, a transfer station, an unloading station and a conveying tray. A grabbing mechanism for grabbing a steel plate is arranged at the end of the mechanical arm. After the hot pressing is completed, the processing module (including a steel plate, a pressing plate and a conveying tray) is conveyed to the unloading station through other mechanisms. The mechanical arm moves to the unloading station, and the grabbing mechanism grabs the steel plate and places it on the conveying tray at the loading station (at this time, the worker at the loading station has placed the fireproof board to be hot pressed on the conveying tray). Then, the steel plate, the fireproof board and the conveying tray are conveyed to the hot pressing process together through the conveying mechanism. At the same time, the worker at the unloading station takes away the hot-pressed fireproof board. Then, the conveying tray is transferred to the transfer station under the action of the conveying mechanism, and then transferred to the loading station, and the next working process is repeated. Therefore, the present invention can realize automatic loading and unloading of the fireproof board during the hot pressing process, reduce labor, improve automation and production efficiency, and promote the pace of realizing the fully automated process of hot pressing of the fireproof board.

[0025] Furthermore, in the above process, the steel plate used in the hot pressing process of the fireproof board can be cleaned by a cleaning brush to ensure the cleanliness of the surface of the steel plate. With the cooperation of other driving mechanisms, the conveying carrier will pass through the electrostatic dust removal rod, and the electrostatic dust removal rod will perform electrostatic dust removal on the surface of the conveying carrier. That is, through the joint action of the cleaning brush and the static elimination rod, the cleanliness of the steel plate and the conveying carrier used in the hot pressing process of the fireproof board can be ensured, thereby ensuring the quality of the pattern of the final hot-pressed fireproof board;

[0026] Furthermore, the cleaning brush and the grabbing mechanism of the present invention are arranged on the same mechanical arm. Since the lower end of the bristles of the cleaning brush extends out of the grabbing mechanism by 4-5 mm in the vertical plane, the movement of the cleaning brush does not interfere with the movement of the grabbing mechanism, that is, only one power drive mechanism is needed to realize the grabbing of the steel plate and the like and the cleaning of the steel plate at the same time. The structural design is ingenious and the cost is relatively low.

[0027] Furthermore, the bristles of the cleaning brush of the present invention are nylon filaments with a diameter of 0.76 mm, which are bonded into bristle clusters with a diameter of 25 mm through the roots of the bristles. The size and material of the bristles of the cleaning brush are reasonably selected, and have a better cleaning effect without scratching the surface of the steel plate.

[0028] Furthermore, the gripping mechanism of the steel plate of the present invention adopts a vacuum suction cup, which will not scratch the surface and pattern of the steel plate compared to the clamping method such as air claws, thereby ensuring the quality of the pattern of the final pressed fireproof board.
