Description

Technical Field

[0001] The utility model relates to the field of electronic manufacturing, in particular to a heat preservation cover device of a heating platform. Background Art

[0002] A high-temperature heating table is a device used to heat objects to high temperatures. It typically consists of a heating element, a temperature control system, and a work surface. High-temperature heating tables are used in many fields, such as soldering and rework of circuit boards in the electronics manufacturing industry, heating reagents or samples in chemical experiments, and heat treating materials in industrial production.

[0003] Traditional high-temperature heating tables are not equipped with an insulation cover structure. In actual use, the heating table loses a lot of heat and the insulation effect is not ideal. At the same time, in order to prevent heat from being lost through the gaps in the ordinary insulation cover, high-temperature resistant rubber strips or asbestos ropes are used to manually seal the gap between the two, which is inefficient. Utility Model Content

[0004] The utility model aims to provide a heat preservation cover device for a heating table which is easy to use and has good heat preservation effect.

[0005] The purpose of the utility model is achieved as follows: A heat preservation cover device for a heating table comprises a heating table, a base and a heat preservation cover body connected to the base;

[0006] A heating platform, which consists of a work surface and a temperature control system base, and the work surface is rectangular;

[0007] The base is composed of two sets of U-shaped plates connected together, the upper and lower sets of U-shaped plates have the same structure and are placed one above the other with their openings facing the same direction; guide posts are provided at the four corners of the upper and lower sets of U-shaped plates, and adjustment nuts are provided on two diagonally opposite guide posts;

[0008] The heat-insulating cover body is a rectangular cavity structure with an opening at the bottom. The heat-insulating cover body is a double-layer shell. The outer side of the heat-insulating cover body is connected to the upper U-shaped plate by bolts. A right-angle positioning plate extends downward from a right angle of the heat-insulating cover body, and a support plate extends inward from the adjacent side plate at a right angle obliquely opposite to the right-angle positioning plate. The support plate is L-shaped.

[0009] A transverse sealing structure is provided in the rectangular cavity above the support plate.

[0010] Preferably, the transverse sealing structure is composed of a silicone pad, a base plate, and a threaded column. The silicone pad is pasted on the front of the base plate. The threaded column is rotatably connected to the center of the back of the base plate. The threaded column passes through the thermal insulation cover. The threaded column and the thermal insulation cover are threadedly connected. A rotating handle is provided at the end of the threaded column.

[0011] Preferably, after the right-angle positioning plate is matched with the work surface at a right angle, a gap is left between the plane where the outer vertical surface of the work surface is located and the plane where the edge of the support plate is located, and the thickness of the silicone pad is greater than the width of the gap.

[0012] Preferably, the length of the silicone pad located on the short side of the support plate is less than the width of the work surface, and the length of the silicone pad located on the long side of the support plate is greater than the length of the work surface.

[0019] 2. A right-angle positioning plate is provided. When the insulation cover is lowered by adjusting the nut, the exposed right-angle positioning plate can first achieve preliminary positioning with the work surface. After achieving preliminary positioning, the insulation cover continues to move down in height. The L-shaped support plate inside the insulation cover will not collide with the work surface, thereby improving the docking efficiency of the two.

[0020] 3. The transverse sealing mechanism is adopted. By rotating the threaded column with the handle, the silicone pad is driven to move inward transversely, thereby sealing the gap between the insulation cover and the work surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-5 As shown, a heat preservation cover device for a heating platform includes a heating platform 1, a base 2 and a heat preservation cover body 3 connected to the base 2;

[0031] The heating table 1 consists of a work surface 101 and a temperature control system base 102. The work surface 101 is rectangular;

[0032] The base 2 is composed of two sets of U-shaped plates 201 connected together. The upper and lower sets of U-shaped plates 201 have the same structure and are placed one above the other with their openings facing the same direction. Guide posts 4 are provided at the four corners of the upper and lower sets of U-shaped plates 201, and two diagonally opposite guide posts 4 are provided with adjustment nuts.

[0033] The thermal insulation cover body 3 is a rectangular cavity structure with an opening at the bottom. The thermal insulation cover body 3 is a double-layer outer shell. The outer side of the thermal insulation cover body 3 is connected to the upper U-shaped plate 201 by bolts; a right-angle positioning plate 5 is extended downward at a right angle of the thermal insulation cover body 3, and the right-angle positioning plate is used for the initial positioning of the work surface. After the initial positioning is achieved, the thermal insulation cover body continues to move down in height, and the L-shaped support plate located in the thermal insulation cover body will not collide with the work surface, thereby improving the docking efficiency of the two; the adjacent side panels at the right angles obliquely opposite to the right-angle positioning plate 5 extend inwardly to provide support plates 6, and the support plates 6 are L-shaped; a transverse sealing structure 7 is provided in the rectangular cavity above the support plate 6.

[0034] like Figure 3-4 As shown, the transverse sealing structure 7 is composed of a silicone pad 701, a base plate 702, and a threaded column 703. The silicone pad 701 is pasted on the front of the base plate 702, and the threaded column 703 is rotatably connected to the center of the back of the base plate 702. The threaded column 703 passes through the thermal insulation cover 3, and the threaded column 703 is threadedly connected to the thermal insulation cover 3. A rotating handle is provided at the end of the threaded column 703. The silicone pad moves transversely on the support plate, and the silicone pad is in close contact with the support plate or a small gap is left. The gap left has limited effect on the internal insulation effect, and can also be used as a ventilation gap to prevent internal overheating and excessive air pressure.

[0035] like Figure 2-5 As shown, after the right-angle positioning plate 5 is matched with the work surface 101 at a right angle, a gap is left between the plane where the outer vertical surface of the work surface 101 is located and the plane where the edge of the support plate 6 is located. The thickness of the silicone pad 701 is greater than the width of the gap. After the silicone pad moves horizontally inward, the thickness of the silicone pad is sufficient to cover the gap, thereby achieving overall sealing.

[0036] like Figure 3-4 As shown, the length of the silicone pad 701 located on the short side of the support plate 6 is less than the width of the work surface 101, and the length of the silicone pad 701 located on the long side of the support plate 6 is greater than the length of the work surface 101, ensuring that the work surface can be embedded in the rectangular cavity.

[0037] like Figure 1-3 As shown, a vent 301 is provided on the top of the heat-insulating cover 3, and the vent 301 is provided with an adjustable valve; if the heating platform may generate gas during operation, the gas can be temporarily discharged through the vent.

[0038] like Figure 1-4 As shown, the outer shell material of the inner layer is selected from stainless steel foil and aluminum-plated film; the outer shell material is selected from aluminum silicate fiber, glass fiber, and rock wool; the outer layer is made of a material with low thermal conductivity, which can effectively reduce heat conduction; for the part of the inner layer that contacts the heating platform, a material that is resistant to high temperature and has good reflective properties is used to reduce radiant heat dissipation.

[0039] like Figure 4 As shown, after the transverse sealing structure 7 collides with the work surface 101, a ventilation gap 8 is left between the silicone pad 701 located on the short side of the support plate 6 and the silicone pad 701 located on the long side of the support plate 6. In order to prevent the accumulation of heat inside the thermal insulation cover and cause danger, a smaller ventilation gap is left to reduce the internal air pressure.

[0040] like Figure 2-3 As shown, a side silicone pad 9 is provided inside the side panel adjacent to the right-angle positioning plate 5. The side silicone pad is embedded in the side panel. After the transverse sealing structure moves inward and collides with the side edge of the work surface, the side silicone pad also collides with the side edge of the work surface, thereby completing the overall thermal insulation seal.

[0041] The working principle of the present invention is explained as follows: when the heating table needs to be insulated, the opening of the U-shaped base is aligned with the heating table and then moved horizontally, and the heating table is placed directly under the insulation cover; then the height of the insulation cover is lowered by adjusting the nut, and the exposed right-angle positioning plate is first preliminarily positioned with the work surface, that is, the right angle of the work table is in conflict with the right-angle positioning plate. After the preliminary positioning is achieved, it is continued to move downward until the lower edge of the insulation cover is located at about half the height of the work surface; the silicone pad is driven to move inward by rotating the threaded column with the handle, so as to achieve the sealing of the gap between the insulation cover and the work surface.

[0042] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
