Description

Technical Field

[0001] This utility model relates to the technical field of tools for processing electrical control cabinets, and in particular to a copper busbar placement rack. Background Technology

[0002] Copper busbars are crucial electrical connection components in electrical control cabinets. To prevent copper from oxidizing upon contact with air, which reduces conductivity, and to prevent corrosion caused by corrosive gases in certain environments, copper busbars are often coated with tin, zinc, or epoxy resin. After coating with epoxy resin, high-temperature curing is required to improve the bond strength between the epoxy resin and the copper busbar. Currently, curing involves vertically placing the copper busbar on a carrier plate with multiple slots. One end of the copper busbar is inserted into the slot, and then curing is achieved through heating. However, this method can lead to uneven thickness in the early stages of curing due to the creeping of the epoxy resin. Utility Model Content

[0003] This utility model provides a copper busbar placement rack to overcome the shortcomings of the prior art and avoid the problem of uneven thickness caused by the creep of epoxy resin, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A copper busbar placement rack includes a rectangular base frame with upper extension rods welded to both ends. Multiple crossbars are threaded through the upper extension rods, and end nuts are threaded to both ends of the crossbars. The inner ends of the end nuts abut against the outer walls of the upper extension rods. Multiple vertical plates are threaded through each pair of crossbars, and a horizontal arm is formed at the upper end of the vertical plate. A placement plate is welded to the upper wall of the horizontal arm, and a placement groove is formed on the placement plate. A rubber pad is provided on the inner wall of the placement groove. The rubber pad is made of heat-resistant hydrogenated nitrile rubber. This rubber pad can prevent scratches on the outer protective layer of the copper busbar. The rubber pad has multiple raised strips or protrusions, which can reduce the contact area between the copper busbar and the placement groove, thereby ensuring the effect of epoxy resin coating. The copper busbar is placed flat in the placement groove, which can reduce the creep of the epoxy resin layer. The copper busbars are spaced apart to ensure thermal stability.

[0006] Furthermore, the upper end of the placement groove extends outward at an angle, thus ensuring that there is an angle between the width direction and the vertical direction of the copper busbar, which further hinders the creep of the epoxy resin.

[0007] Furthermore, the lower end of the rectangular base frame is fitted with multiple casters by screws to facilitate the movement and transfer of the copper busbar.

[0008] Furthermore, a transverse hole is provided on the cross arm, and a spline sleeve is inserted through the transverse hole. A turntable is installed at both ends of the spline sleeve by screws. The turntable is located on both sides of the cross arm and is eccentrically positioned at both ends of the spline sleeve. A spline rod is inserted through the spline sleeve so that the copper busbar can be pushed out by the rotation of the eccentric plate, thereby facilitating the removal of the copper busbar.

[0009] Furthermore, the spline rod has an L-shaped structure to facilitate its pull-out operation.

[0010] The advantages of the above technical solution are:

[0011] This invention provides a mounting rack for curing epoxy resin. When the copper busbar is placed, it is laid flat with an angle between its width and vertical directions. This can reduce the creep of the epoxy resin, thereby improving the uniformity of the thickness after curing to a certain extent. However, it cannot completely guarantee that the epoxy resin will not creep at all. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0013] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0014] Figure 2 A magnified view of point A is shown.

[0015] Figure 3 A magnified view of point B is shown. Detailed Implementation

[0016] like Figures 1-3 As shown, a copper busbar placement rack includes a rectangular base frame 1. Multiple casters 2 are mounted on the lower end of the rectangular base frame 1 by screws. Upper extension rods 3 are welded to both ends of the rectangular base frame 1. Multiple crossbars 31 are inserted between the upper extension rods 3. End nuts 32 are threaded to both ends of the crossbars 31. The inner end of the end nut 32 abuts against the outer wall of the upper extension rod 3. Multiple vertical plates 4 are inserted on each pair of crossbars 31. A horizontal arm 40 is formed at the upper end of the vertical plate 4. A placement plate 41 is welded to the upper wall of the horizontal arm 40. A placement groove 42 is opened on the placement plate 41. A rubber pad is provided on the inner wall of the placement groove 42. The upper end of the placement groove 42 extends outward at an angle.

[0017] A transverse hole 43 is provided on the cross arm 40. A spline sleeve 44 is inserted through the transverse hole 43. A turntable 45 is installed at both ends of the spline sleeve 44 by screws. The turntable 45 is located on both sides of the cross arm 40 and is eccentrically positioned at both ends of the spline sleeve 44. A spline rod 46 is inserted through the spline sleeve 44. The spline rod 46 has an L-shaped structure.

[0018] In this embodiment, the operator places the copper busbars flat in each placement slot 42, with an angle between the width and vertical directions of the placed copper busbars. The copper busbars coated with epoxy resin are then transferred to a curing device and cured at 150°C. During the curing process, the inclined placement of the copper busbars reduces the creeping ability of the epoxy resin, thereby improving the uniformity of the epoxy resin thickness compared to existing placement methods. After curing, the operator moves the spline rod 46 under one of the copper busbars and then rotates the spline rod 46. When the spline rod 46 rotates, the outer periphery of the turntable 45 acts on the lower side of the copper busbar, causing the copper busbar to move upward from the placement slot 42 and then be removed.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
