[0036] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] According to the concept of this application, Figures 1 to 6To describe an embodiment of the heat exchanger plate adsorption assembly. Specifically, the heat exchanger plate adsorption assembly is constructed as a split structure, which has two components, namely a negative pressure head 10 and a high-density sponge 11. By arranging the high-density sponge 11 below the negative pressure head 10, the high-density sponge 11 deforms when it is pressurized, so that the high-density sponge 11 can completely fit the uneven surface of the heat exchange plate, and form a closed negative pressure inside it, so that the adsorption assembly can adapt to heat exchange plates with different roughness, and through the fixing ring 12 and the support rod 14, the inner wall of the high-density sponge 11 can be supported, thereby improving the stability of the device.

[0038] Please refer to Figures 1 to 6 , a heat exchanger fin adsorption assembly, comprising a negative pressure head 10 and a high-density sponge 11;

[0039] A negative pressure head 10, with a fixing ring 12 fixedly installed just below the negative pressure head 10;

[0040] High-density sponge 11, which is fixedly installed just below the fixing ring 12. At least one through hole is provided on the outer side of the fixing ring 12. A negative pressure cavity is formed between the negative pressure head 10 and the high-density sponge 11 through the through hole. The high-density sponge 11 wraps the negative pressure cavity.

[0041] The negative pressure head 10 presses down the high-density sponge 11 through the fixing ring 12 , so that the high-density sponge 11 is flat, and the flat high-density sponge 11 falls into the pressing area of ​​the fixing ring 12 as a whole.

[0042] The fixing ring 12 is installed between the high-density sponge 11 and the negative pressure head 10 through the internal mounting hole. When the negative pressure head 10 is pressed down through the fixing ring 12, the high-density sponge 11 is pressed into a flat shape. At this time, the pores on the side wall of the high-density sponge 11 are squeezed and closed, so that a seal is formed between the inner cavity of the high-density sponge 11 and the heat exchange plate and the negative pressure head 10. The through hole on the outside of the fixing ring 12 facilitates air circulation between the negative pressure cavity and the negative pressure head 10, which is convenient for rapid adsorption;

[0043] The high-density sponge 11 can be deformed when it comes into contact with an uneven surface and can fill the grooves on the surface, so that the negative pressure head 10 can be firmly adsorbed on the heat exchange plates with different roughness and adapt to heat exchange plates with different roughness. The thickness of the high-density sponge 11 is 5mm-20mm, which can just fill the grooves on the surface of the heat exchange plate, avoiding loose adsorption due to being too large or too small, thereby improving the stability of adsorption.

[0044] At least one support rod 14 is equidistantly arranged on the outside of the fixing ring 12. The fixing ring 12 can evenly flatten the high-density sponge through the peripheral support rods 14. The support rod 14 is fixedly connected to the high-density sponge 11 at one end away from the fixing ring 12, and is used to fix the position of the fixing ring 12. The high-density sponge 11 is evenly pressed down by the fixing ring 12 and the support rod 14. Because the fixing ring 12 and the support rod 14 are made of hard plastic, alloy or metal support, they can provide support for the high-density sponge 11, which is beneficial to improving the stability of the support of the high-density sponge 11. A bolt hole 13 is arranged at the center of the inner side of the fixing ring 12. The bolt passes through the bolt hole 13 to connect the high-density sponge 11 and the negative pressure head 10. The high-density sponge 11 is easily disassembled and replaced by bolt fixation. Due to the scale and rust generated on the surface of the heat exchange plate after long-term use, the surface of the high-density sponge 11 is easily blocked after multiple contacts, resulting in unreliable fixation. The cooperation between the bolts and the bolt holes 13 can save replacement time and improve work efficiency.

[0045] The upper end of the negative pressure head 10 is coaxially fixedly connected with a connector 102, and an air pipe 101 is fixed at the center of the upper end of the connector 102; the upper end of the negative pressure head 10 is coaxially provided with a connector 102, and the upper end of the connector 102 is penetrated by an air pipe 101, and the air pipe 101 forms a communication structure with the negative pressure head 10 through the connector 102, and the end of the air pipe 101 away from the negative pressure head 10 is connected to an air pump, and the air pump or vacuum generator extracts air from the bottom of the negative pressure head 10 through the air pipe 101, so that when the negative pressure When the head 10 is adsorbed on the surface of the heat exchange plate, a negative pressure chamber is formed inside the high-density sponge 11, so that the heat exchange plate can be firmly fixed and grasped, thereby facilitating the automatic grasping of the processing machine tool and improving the automation system of the device. The outer side of the connecting piece 102 is threadedly connected to the connecting plate 9, and one end of the connecting plate 9 is penetrated by a mounting hole 91, and the connecting piece 102 is coaxially arranged with the mounting hole 91. The connecting piece 102 is threadedly connected to the mounting hole 91, so that the adsorption component is connected to the robot arm device, thereby facilitating assembly.

[0046] A mobile robotic arm device includes an adsorption component and a robotic arm device, wherein the robotic arm device includes a connecting rod 7, a support plate 8 and a connecting plate 9, the connecting plate 9 is slidably connected to the support plate 8 on the side away from the adsorption component, limiting grooves 92 are fixed on both sides of the connecting plate 9, and the inner side of the support plate 8 is provided with a limiting protrusion adapted to the limiting groove 92, the protruding shape of the limiting protrusion is the same as the cross-section of the limiting groove 92, which is used to display the sliding direction of the connecting plate 9 to prevent it from shaking, which is beneficial to improve the stability of the device, and at the same time, because the connecting plate 9 fixes the adsorption component, the distance between the two groups of adsorption components can be adjusted by adjusting the position of the two groups of connecting plates 9, so that it can adapt to heat exchange plates of different sizes.

[0047] The connecting rod 7 passes through the support plate 8 and is rotatably connected to the support plate 8. The upper end of the connecting rod 7 passes through the support arm 5 and is rotatably connected to the support arm 5. The upper end of the connecting rod 7 is coaxially connected to the output end of the second servo motor 6 through a coupling. The second servo motor 6 drives the connecting rod 7 and the support plate 8 to rotate the connecting rod 7 in a circle, which is convenient for adjusting the reverse direction of the support plate 8 and the adsorption component, thereby improving the flexibility of the robot arm device.

[0048] A rotating shaft 71 is fixed at the connection between the connecting rod 7 and the support plate 8, so that the connecting rod 7 can drive the support plate 8 to rotate synchronously, thereby improving the stability of the connection. A connecting block 4 is inserted at the end of the support arm 5 away from the second servo motor 6. The connecting block 4 is used to connect the electric telescopic rod 1a and the mechanical arm device, and the structure is simple.

[0049] A rotating seat 2 is movably connected to the inner side of the connecting block 4, and a first servo motor 3 is fixedly connected to the upper end of the rotating seat 2. The rotating seat 2 and the mechanical arm device are driven to rotate by the first servo motor 3, so that the mechanical arm device and the adsorption assembly can be transferred together to the top of the corresponding installation area of ​​the heat exchange plate to adjust the position of the heat exchange plate. An electric telescopic rod 1a is fixedly connected to the lower end of the rotating seat 2, and the lower end of the electric telescopic rod 1a is fixed to the base 1. The electric telescopic rod 1a can enable the device to gently handle the heat exchange plate, which is beneficial to improve the stability of the device. Two groups of adsorption assemblies are symmetrically arranged about the vertical center line of the support plate 8 to improve the stability of the adsorption assembly.

[0050] The heat exchange plate adsorption assembly provided by the utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0051] The heat exchanger adsorption assembly and its mobile mechanical arm are arranged at the corner of the pre-installed conveyor line and the rotary silo. When in use, the heat exchanger above the pre-installed conveyor line moves with the conveyor belt to the bottom of the negative pressure head 10, and the first servo motor 3 drives the rotating seat 2 to rotate. At the same time, the rotating seat 2 drives the connecting block 4 and the support arm 5 to rotate to the top of the heat exchanger on the pre-installed conveyor line. At this time, the electric telescopic rod 1a contracts downward and drives the negative pressure head 10 to move downward. The high-density sponge 11 is deformed to fill the groove on the surface of the heat exchanger until the high-density sponge 11 is compressed into a flat shape, and its side pores are closed to form a sealed state, so that The high-density sponge 11 is completely fitted to the heat exchange plate. At this time, the air pump is started, and the air pump draws air to the bottom of the negative pressure head 10 through the air pipe 101. At this time, a negative pressure state is formed under the negative pressure head 10, thereby adsorbing and grabbing the heat exchange plate, and then the first servo motor 3 is started again to move the heat exchange plate to the top of the heat exchange plate placement rack. At the same time, the electric telescopic rod 1a contracts downward until the heat exchange plate is superimposed on the top of the placement rack. Thereafter, the air pump is turned off to separate the adsorption assembly from the heat exchange plate, thereby completing the alignment. When the high-density sponge 11 needs to be replaced, only the bolt in the center of the fixing ring 12 needs to be unscrewed to remove the high-density sponge 11.
