Description

Technical Field

[0001] The invention relates to an operating platform of a machine or a production line, and in particular to a combined constant temperature adsorption platform. Background Art

[0002] The structure of the vacuum adsorption platform currently used in the market is a frame made of welded profiles to fix the honeycomb core, and then the bottom plate and panel are bonded to the bottom and surface respectively. The principle is that the filling and supporting role of the honeycomb core makes the flatness of the panel of the entire platform reach a very high precision, and the flatness can reach an accuracy of 0.05mm-0.15mm. But because of such a high-precision platform, it is more susceptible to the influence of the external environment. In actual use, the machine will generate high temperature during operation, and the temperature directly acts on the workpiece and the panel, causing the temperature of the platform panel to rise. There is a large temperature difference between the panel and other parts of the platform, and the deformation of each part due to temperature is inconsistent. The platform panel is seriously deformed, its flatness accuracy is damaged, and it no longer meets the requirements of the machine. The quality of the processed products is unstable and the products are unqualified.

[0003] In addition, our company has developed a new generation of products, such as the attached Figure 1 and Figure 2 As shown, the honeycomb core structure is adopted. In order to control the temperature, multiple flow channels 1.3 need to be set through the panel 1. The flow channels 1.3 and the adsorption holes 1.1 are arranged at intervals. This increases the difficulty of manufacturing the panel, increases the cost and makes it difficult to ensure the shape accuracy of the panel. Summary of the invention

[0007] Preferably, the flow channel array groups are spaced and positioned and planarly supported by flow channel plug-in plates and flow channel support plates which are transversely arranged in the frame.

[0028] See also Figure 3-Figure 8 A combined constant temperature adsorption platform includes a panel 10, a flow channel array group 20, a frame 30 and a bottom plate 40.

[0029] The panel 10 and the bottom plate 40 are connected to the upper and lower sides of the frame 30 by bonding, screw connection or the like.

[0030] The flow channel group 20 is filled in the frame 30, the bottom plate 40 is provided with an exhaust flange mounting hole 41, and the adsorption holes 11 are evenly distributed on the panel 10. The flow channel group 20 is composed of hollow flow channel tubes 21 arranged side by side, and the two ends of the flow channel tubes 21 are inserted into the slots of the flow channel group plug 22.

[0031] The flow channel array group 20 is spaced and positioned and supported in a plane by a flow channel plug-in plate 33 and a flow channel support plate 34 which are transversely arranged in the frame 30 .

[0032] See also Figure 4 and Figure 5 The flow channel plug-in plate 33 and the flow channel support plate 34 are evenly spaced and arranged between the two longitudinal beams 31 of the frame 30 .

[0033] See also Figure 6 A surface positioning plate 212 is fixedly arranged on the upper surface of the flow channel tube body 211 of the flow channel tube 21. The flow channel tube body 211 is a hollow tube, and the inner hole 213 of the tube body is formed.

[0034] See also Figure 7 and Figure 8 , flow channel spacing grooves 331 are evenly arranged on the top surface of the flow channel plug-in plate 33, and the upper surface of the flow channel support plate 34 is a horizontal support plate surface 341. Two supporting ridges 3411 are raised upward on both sides of the horizontal support plate surface 341, and the two supporting ridges 3411 serve as the actual support body of the horizontal support plate surface 341.

[0035] See also Figure 4 and Figure 6 The two ends of the flow channel tube 21 are inserted into the grooves of the flow channel array plug 22, and the flow channel tube body 211 of the flow channel tube 21 is evenly spaced and supported by the flow channel plug plate 33 and the flow channel support plate 34. This improves uniform heat dissipation and stability.

[0036] Preferably, the flow channel plug plate 33 and the flow channel support plate 34 are hollow plate structures, or are formed by bending a plate structure, and through holes are provided on the side plates of the flow channel support plate 34, so as to reduce the weight of the overall structure and improve the lightweight design.

[0037] Preferably, the adsorption holes 11 are arranged on the upper surface of the panel 10 .

[0038] In order to allow the coolant, ie, water fluid, in the flow channel tube 21 to communicate, through holes are provided at intervals in the slots of the flow channel array plug 22 so that the ends of the flow channel array 20 are connected.

[0039] Preferably, connecting screw holes are provided on the two end pressure plates 32 of the frame 30 to realize threaded connection.

[0040] In order to improve the sealing performance, a sealant is provided between the butt joint surface of the end pressure plate 32 and the flow channel array plug 22 .

[0041] In addition, the air outlet flange mounting holes 41 are arranged on the bottom plate 40 at equal intervals.

[0042] The end pressure plate 32 is provided with mounting holes, and the mounting holes are respectively provided with inlet joints and outlet joints for connecting with pipelines of external equipment.

[0043] The external fan is fixedly connected to the multiple exhaust port flange mounting holes 41 of the platform through pipelines and flange joints. The exhaust port flange mounting holes 41 are connected to the flow channel array group 20, and the adsorption holes 11 on the panel 10 are correspondingly connected to the flow channel array group 20. When the external fan is working, negative pressure is generated, and the air path formed by the platform generates adsorption force on the adsorption holes 11 on the panel 10 to achieve the function of adsorbing workpieces. At the same time, because there are multiple exhaust port flange mounting holes 41, valve control elements can be set on the external pipeline, so that the area of ​​the platform can be independently controlled to determine whether it is adsorbed, thereby greatly improving the utilization rate of the fan.

[0044] The external pump and temperature control device are connected to the inlet and outlet joints on the panel through pipes. When the external pump is working, it pushes the coolant into the inlet joint, then flows around the panel loop and out of the outlet joint, then passes through the external temperature control device to regulate the temperature of the coolant, and finally enters the inlet joint again through the external pump, forming a continuously circulating cooling loop. Through the continuous temperature control of the temperature control device, the constant temperature control of the platform can be achieved.

[0045] The constant temperature adsorption platform provided by the present invention uses a coolant circulation structure and arranges multiple flow channels on the panel of the platform, which can form a loop with external equipment. The heat of the platform is exported through the temperature control system, and the panel is controlled and maintained within the required temperature range, thereby eliminating the panel deformation caused by temperature difference, ensuring that the flatness accuracy of the platform panel is not destroyed, and stabilizing the quality of the processed products.

[0046] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
