Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of solder paste storage, and relates to an automatic discharging system for a solder paste storage cabinet. Background Art
[0002] The quality of solder paste plays a crucial role in the SMT soldering process. After production, solder paste should be stored in a refrigerator immediately, at a temperature between 2°C and 10°C. When removing the paste from the refrigerator, it must be allowed to warm to room temperature. This is because the paste is much colder than room temperature immediately after removal. Opening the bottle without warming it up beforehand can easily cause moisture to condense and adhere to the solder paste. During reflow soldering, the intense heat rapidly vaporizes this moisture, causing "tin popping," solder beads, and even damage to components. The correct way to warm the paste is to leave it to thaw naturally at room temperature, leaving the bottle unopened. This allows the paste to naturally return to room temperature. The specific warming time varies with the season, taking approximately 2-3 hours in the hot summer and 4-6 hours in other seasons. Currently, there are only single refrigerated cabinets on the market, and solder paste needs to be refrigerated manually. The solder paste in the refrigerator must be placed in a rewarming cabinet for rewarming several hours before production. This process usually requires manual operation in the early morning hours to prepare for early morning production. The manual process is cumbersome, the workload is large, the time control is inaccurate, the management quality of the solder paste is not ideal, and the small unit storage and retrieval of the solder paste cannot be achieved. On the one hand, the above storage and retrieval methods consume working time and reduce work efficiency. On the other hand, they increase the labor intensity of workers and affect the production efficiency of the entire production line. Utility Model Content

[0015] The technical solution of the present invention is described below in conjunction with the accompanying drawings and implementation methods.
[0016] like Figure 1 As shown, an automatic discharging system for a solder paste storage cabinet includes a bracket 1, an electric cylinder 3 is provided below the bracket 1, and the two are connected by a bolt 2, specifically, the bolt 2 is a hexagon socket bolt; a soft magnetic plate 6 is provided below the electric cylinder 3, and the two are connected by a connecting piece 4, the middle part of the connecting piece 4 is threadedly connected to the protruding end of the electric cylinder 3, and the side part is connected to the soft magnetic plate 6 through a plurality of bolt and nut assemblies 5; a door frame 7 is provided below the soft magnetic plate 6, and the two are slidably connected.
[0017] The door frame 7 is in the shape of a U, and is provided with a slot running through its body and an opening in the middle. The soft magnetic plate 6 is inserted into the slot of the door frame 7; in some embodiments, the inner wall of the slot of the door frame 7 is affixed with magnetic materials such as magnetic strips, and the magnetism of the magnetic material is exactly opposite to that of the soft magnetic plate 6, so that the soft magnetic plate 6 is always adsorbed on the inside of the slot when sliding up and down, so as to ensure the sealing and cooling effect of the refrigerator.
[0018] A release slide 8 is provided on one side of the opening and a receiving slide 11 is provided on the other side, and the two are connected to form a channel; wherein, the release slide 8 is inclined, and an angle of 20 degrees is formed between the end away from the door frame 7 and the horizontal plane; the receiving slide 11 is bent, and an angle of 20 degrees is formed between the end close to the door frame 7 and the horizontal plane, and the other end is horizontally set to achieve speed buffering and ensure that the solder paste is in an upright state when it is stationary outside; in some embodiments, a fence is provided on the outside of the receiving slide 11 to prevent the transport trolley from falling or sliding out of the receiving slide 11 due to a fast sliding speed.
[0019] The door frame 7 is connected to the door of the solder paste storage cabinet, and the release slide 8 is located on the inside of the solder paste storage cabinet door, and the receiving slide 11 is located on the outside of the solder paste storage cabinet door. It should be noted here that a through hole with the same shape and size as the opening of the door frame 7 needs to be cut in the door of the solder paste storage cabinet in advance to facilitate the connection between the solder paste storage cabinet and the door frame 7.
[0020] like Figure 2As shown, the utility model also includes a transport trolley 10, which is used to carry a number of boxes 9 filled with solder paste and move back and forth on the channel formed by the release slide 8 and the receiving slide 11; specifically, the transport trolley 10 is provided with a number of receiving grooves 10a for installing the box bodies 9, and a number of universal wheels 10b are provided at the bottom, wherein the receiving grooves 10a are cylindrical, the height of which is less than the height of the box body 9, and the opening diameter is slightly larger than the diameter of the box body 9.
[0021] The present invention realizes the lifting and lowering of the soft magnetic plate 6 by controlling the forward and reverse rotation of the electric cylinder 3, thereby realizing the opening and closing control of the refrigerator door. Specifically, when the cabinet door is not opened, the carrying trolley 10 is located in the solder paste storage cabinet due to the blocking effect of the soft magnetic plate 6. When the soft magnetic plate 6 is lifted by the electric cylinder 3, the carrying trolley 10 slides along the release slide 8 to the receiving slide 11 under the action of gravity. In addition, the on-site control system can also be used to limit the start and stop time of the electric cylinder 3, so that the soft magnetic plate 6 can realize the automatic timed shutdown function and automatically descend to the initial position after the specified time. Therefore, the present invention can not only realize the automatic taking and placing of solder paste, but also ensure the sealing of the solder paste storage cabinet.
