[0002] Honeycomb material is a sandwich structure, whose core layer is composed of a series of hexagonal, quadrilateral or other shaped cells, and relatively thin panels are bonded to both sides of the core layer. Honeycomb materials usually have the characteristics of light weight, high strength, flame retardancy, sound insulation, heat insulation and corrosion resistance, and are widely used in the fields of aerospace, construction, automobile manufacturing, etc. due to their unique structure and excellent performance.

[0003] Due to the special structure of honeycomb materials, in order to ensure the bonding effect between the core layer and the panel, a pressing mechanism is usually used to make the glue coated fully contact with the core layer and the panel. However, the glue has a certain fluidity, making the core layer and the panel prone to displacement under the influence of the glue during the extrusion process, and the core layer and the panel will be misaligned after bonding, which affects the processing yield and use effect of honeycomb materials.

[0004] Therefore, a new solution is needed to solve the problem that the core layer and the panel are prone to displacement during the bonding and reinforcement process. Content of the Utility Model

[0019] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Embodiment: The honeycomb material workpiece pressing mechanism, as Figure 1 and Figure 2 shown, includes an equipment body 1. The equipment body 1 includes a robotic arm 2, three conveyor belts 3, and a fastening device 4 arranged in sequence along the conveying direction of the honeycomb material. Both the robotic arm 2 and the fastening device 4 are made of aluminum alloy material. The aluminum alloy material has the characteristics of light weight and high strength, which can ensure the stability of the equipment body 1 during processing. The conveyor belt 3 includes a feeding part 12 and an extrusion part 13 arranged in sequence along the conveying direction of the honeycomb material. A driving motor for driving the conveyor belt 3 to move is provided on the side wall of the equipment body 1. The honeycomb material to be processed can be placed on the feeding part 12 of the conveyor belt 3 through the robotic arm 2, and the honeycomb material to be processed is conveyed when moving along with the conveyor belt 3. The fastening device 4 includes an extrusion device 5 and a rectangular base 6. Both ends of the base 6 are respectively fixed on the inner side walls of the equipment body 1. The base 6 is located directly below the extrusion part 13. The extrusion device 5 is fixed directly above the extrusion part 13 through support rods on both sides of the equipment body 1.

[0021] As Figure 1 、 Figure 2 and Figure 4 shown, the extrusion device 5 includes a cylindrical extrusion rod 10 and a hydraulic component for driving its telescopic movement. The hydraulic component includes a piston rod, a hydraulic oil tank, a hydraulic cylinder, a hydraulic pump, a hydraulic valve, a driving motor, etc. By opening and closing the hydraulic valve, the speed and pressure of the hydraulic oil entering the hydraulic cylinder can be controlled, so as to drive the extrusion rod 10 to perform telescopic movement. When the extrusion rod 10 moves in the direction close to the base 6, it can drive the honeycomb material and the conveyor belt 3 to move in the direction close to the base 6 together.

[0022] As Figures 1 - 3As shown in the figure, a limiting groove 7 is provided on one side of the base 6 close to the extrusion device 5. The cross-section of the limiting groove 7 is rectangular, and the length and width of the limiting groove 7 are respectively the same as the length and width of the honeycomb material. Four rectangular guiding surfaces 8 are provided at the notch of the limiting groove 7 on the base 6. One side of the guiding surface 8 close to the groove 9 is fixedly connected to the opening of the limiting groove 7. The guiding surface 8 is inclined in the direction close to the bottom surface of the limiting groove 7. The distance between the bottom surface of the limiting groove 7 and the side of the guiding surface 8 close to the groove 9 is greater than the thickness of the honeycomb material. The four guiding surfaces 8 can adjust the moving direction of the honeycomb material while it is moving, so that the honeycomb material can be aligned and enter the limiting groove 7.

[0023] As Figures 1 - 4 shown in the figure, the base 6 is provided with three grooves 9 communicating with the limiting groove 7. The cross-section of the groove 9 is concave-shaped. The three grooves 9 are symmetrically arranged along the width direction of the equipment body 1. The three conveyor belts 3 are respectively located directly above the three grooves 9. The conveyor belt 3 is made of rubber material, and the rubber material has good wear resistance, elasticity and anti-slip properties, which can prevent the honeycomb material on the conveyor belt 3 from shifting during the movement. The width of the groove 9 is greater than the width of the conveyor belt 3, and the depth of the groove 9 is greater than the thickness of the conveyor belt 3. When the honeycomb material moves to abut against the bottom surface of the limiting groove 7, the conveyor belt 3 is stretched under pressure and sinks into the groove 9. At this time, the pressure of the extrusion rod 10 can bond and reinforce the core layer and the panel. At the same time, the limiting groove 7 can limit the displacement between the panel and the core layer while extruding the honeycomb material, thus ensuring the use effect of the honeycomb material and improving the processing yield of the equipment body 1. A nano-coating is sprayed on the limiting groove 7, the four guiding surfaces 8 and the three grooves 9. The component of this nano-coating is silicon dioxide. The nano-coating can effectively prevent glue from remaining on the base 6.

[0024] As Figures 1 - 4 shown in the figure, a cylindrical buffer pad 11 is bonded to one end of the extrusion rod 10 close to the honeycomb material. This buffer pad 11 is made of rubber material. The buffer pad 11 can provide a certain buffering effect when the extrusion rod 10 applies pressure to the honeycomb material, and at the same time prevent damage to the honeycomb material during the extrusion process. After the extrusion rod 10 completes the pressing and reinforcement of the honeycomb material, it moves in the direction away from the base 6. At this time, the three conveyor belts 3 will recover elastically by themselves and drive the honeycomb material to pass out of the limiting groove 7 along the direction close to the extrusion device 5. The moving speed of the extrusion rod 10 is less than the rebound speed of the conveyor belt 3 to prevent the conveyor belt 3 from bouncing the honeycomb material during the rebound process. A storage basket 14 made of aluminum alloy material is detachably connected to one end of the equipment body 1 close to the fastening device 4. The processed honeycomb material is conveyed by the conveyor belt and falls into the storage basket 14. Through the mutual cooperation of the robotic arm 2, the three conveyor belts 3 and the fastening device 4, continuous processing operations can be carried out on a number of honeycomb materials to be processed.

[0025] Working principle: When the honeycomb material to be processed is conveyed to the extrusion part 13 through the conveyor belt 3, the hydraulic component drives the extrusion rod 10 to extend in the direction close to the base 6, so as to drive the honeycomb material and the conveyor belt 3 to move in the direction close to the base 6 together. The four guiding surfaces 8 can adjust the moving direction of the honeycomb material while it is moving, so as to drive the honeycomb material to align and enter the limiting groove 7. When the honeycomb material moves to abut against the bottom surface of the limiting groove 7, the conveyor belt 3 is stretched under pressure and sinks into the groove 9. At this time, the honeycomb material is compacted and strengthened by the extrusion rod 10. The limiting groove 7 restricts the displacement between the panel and the core layer while extruding the honeycomb material. After the extrusion rod 10 completes the extrusion and strengthening operation on the honeycomb material, it moves in the direction away from the base 6. At this time, the conveyor belt 3 will recover elastically by itself and drive the honeycomb material to pass out of the limiting groove 7 in the direction close to the extrusion device 5. The honeycomb material to be processed is placed on the feeding part 12 by the robotic arm 2. At this time, the processed honeycomb material and the honeycomb material to be processed are conveyed together through the conveyor belt 3. When the honeycomb material to be processed is conveyed to the extrusion part 13, the processed honeycomb material falls into the storage basket 14. At this time, the conveyor belt 3 stops moving and performs the next round of extrusion and strengthening operation.

[0026] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
