Description

Technical Field

[0001] This utility model relates to the field of material storage equipment technology, and in particular to a solder paste storage cabinet. Background Technology

[0002] Solder paste is an indispensable key material in surface mount technology (SMT) production, and its quality directly affects the soldering quality of electronic components and the reliability of the final product. Solder paste is typically composed of tin alloy powder and flux, and has strict requirements for storage conditions, especially storage time and temperature. To ensure soldering quality, electronic manufacturing companies generally follow the "first-in, first-out" material management principle, that is, prioritizing the use of solder paste that has entered the warehouse first, to prevent problems such as flux deterioration and solder powder oxidation caused by prolonged storage, thereby avoiding soldering defects such as cold solder joints and bridging.

[0003] Currently, the industry primarily uses traditional warehouse shelves or ordinary lockers for solder paste storage management. These storage devices are typically simple layered or grid-style structures. In practice, operators need to manually identify the production date or warehousing label on the solder paste bottle and manually select the oldest bottle from a pile of solder paste for use. This management method, which relies on manual identification and memory, has the following drawbacks: on busy production lines, it is easy to mistakenly use the wrong bottle due to human negligence or convenience, leading to the failure to strictly enforce the "first-in, first-out" principle, resulting in some solder paste accumulating and expiring, causing unnecessary material waste and economic losses.

[0004] Therefore, we designed a solder paste storage cabinet. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a solder paste storage cabinet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solder paste storage cabinet, comprising:

[0008] The cabinet has an entrance at the top and an exit at the bottom front.

[0009] The flow channel, whose upper and lower ports correspond to the inlet and outlet respectively, is used to store and guide the solder paste container, so that the solder paste container can roll along its path;

[0010] The flow channel includes at least one first inclined flow guide plate and at least one second inclined flow guide plate. The first and second inclined flow guide plates are inclined in opposite directions and are staggered vertically.

[0011] Furthermore, multiple viewing holes are evenly spaced along the path of the flow channel on both the left and right side walls of the cabinet.

[0012] Furthermore, the front and rear side walls of the cabinet are provided with transparent slots corresponding to the deflection areas of the flow channel.

[0013] Furthermore, a concave notch is provided in the middle of the outlet in the height direction.

[0014] Furthermore, the inner bottom surface of the flow channel is provided with an upwardly protruding first ridge and a second ridge along its path;

[0015] The first protruding ridge and the second protruding ridge are spaced apart along the width direction of the flow channel.

[0016] Furthermore, the top of the first convex ridge is higher than the top of the second convex ridge.

[0017] Furthermore, a buffer strip is fitted onto the top of both the first and second protruding ridges.

[0018] Furthermore, the inner cavity of the cabinet is provided with at least one partition for dividing the inner cavity of the cabinet into at least two chambers along the left-right direction.

[0019] Furthermore, the tilt angle of the first inclined guide plate and the second inclined guide plate is 3-8 degrees.

[0020] Furthermore, the insertion port is located on the top front side of the cabinet; a handle is installed in the middle of the front side wall of the cabinet.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Through the meandering flow channel formed by the first and second inclined guide plates with opposite inclination and staggered vertical arrangement, the solder paste can automatically and orderly roll to the dispensing outlet by gravity after being poured in, completely avoiding the chaos caused by manual searching and retrieval, ensuring that the solder paste stored first is used first, effectively preventing the solder paste from expiring and deteriorating due to long-term accumulation, and at the same time greatly reducing the manpower and time costs of warehouse management;

[0023] 2. By setting viewing holes evenly distributed along the flow path on the left and right side walls of the cabinet, and opening viewing slots in the channel deflection areas on the front and rear side walls, the storage cabinet can be observed from multiple angles and without blind spots to observe the rolling status of the solder paste can, the remaining inventory, and whether there is any blockage, which greatly improves the convenience of use and the orderliness of management.

[0024] 3. The bottom surface of the guide channel is provided with a first convex ridge and a second convex ridge with different heights, which together form an effective guiding and anti-slip mechanism, ensuring that the solder paste can always roll along the center of the predetermined path. A buffer strip is sleeved on the top of the convex ridge, which can significantly absorb the impact energy generated when the solder paste can rolls and changes direction. This not only effectively reduces operating noise, but also avoids deformation or damage to the solder paste can due to bumps.

[0025] 4. By installing vertical partitions inside the cabinet, the internal space can be easily divided into multiple independent chambers, thereby enabling the partitioning, classification, storage, and management of solder paste cans of different types, models, or batches without interference, greatly improving the equipment's versatility and space utilization. In addition, the concave notch design of the retrieval outlet is ergonomic, making it easy for people to reach in and put in the solder paste cans. The handle on the front of the cabinet not only facilitates the handling of the entire equipment but also ensures that the solder paste cans placed inside the cabinet will not fall out.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Example 1, please refer to Figures 1 to 5 A solder paste storage cabinet includes a cabinet body 1 and a flow channel disposed therein.

[0037] The cabinet 1 is generally a vertical box structure. It has an inlet 11 at the top for inserting solder paste cans. The bottom front side of the cabinet 1 has an outlet 12 for removing solder paste cans that have been rolled there.

[0038] The flow channel is located inside the cabinet 1, with its upper end connected to the top inlet 11 and its lower end connected to the front bottom outlet 12. This flow channel is used to store and guide solder paste cans by gravity, so that after the solder paste cans are put in from the inlet 11, they can automatically roll along the path of the flow channel to the outlet 12, realizing "first-in, first-out" inventory management.

[0039] The flow channel includes at least one first inclined flow guide plate 2 and at least one second inclined flow guide plate 3. In this embodiment, as... Figure 3 and Figure 5 As shown, the first inclined guide plate 2 and the second inclined guide plate 3 are arranged alternately, with opposite inclination directions. For example, the first inclined guide plate 2 tilts from the upper front to the lower rear of the cabinet 1, while the immediately following second inclined guide plate 3 tilts from the upper rear to the lower front of the cabinet 1, repeating this process to form a meandering zigzag rolling path. This design greatly extends the rolling path of the solder paste can within the cabinet, increasing storage capacity within the limited cabinet height. To ensure that the solder paste can roll smoothly under its own weight, the tilt angle of the first inclined guide plate 2 and the second inclined guide plate 3 is preferably set between 3 and 8 degrees.

[0040] To facilitate observation of the storage and rolling status of the solder paste containers inside the cabinet, such as... Figure 2 and Figure 3 As shown, multiple viewing holes 13 are evenly spaced along the entire flow channel path on the left and right side walls of cabinet 1. Furthermore, as... Figure 1-2 and Figure 5 As shown, on the front and rear side walls of the cabinet 1, corresponding to the deflection area of ​​the flow channel (i.e., the junction of the first inclined flow guide plate 2 and the second inclined flow guide plate 3), there are viewing slots 14, providing a more direct viewing angle. When the solder paste can gets stuck in the flow channel, it can be moved through the viewing hole 13 and the viewing slot 14 to solve the problem of the solder paste can getting stuck.

[0041] To facilitate users reaching into the retrieval port 12 to retrieve the solder paste container, such as Figure 1 and Figure 3 As shown, the outlet 12 has a recessed notch 15 in the middle of the height direction.

[0042] Preferably, at least one vertical partition 16 is provided in the inner cavity of the cabinet 1. The partition 16 divides the inner cavity of the cabinet 1 into at least two independent chambers along the left-right direction. Each chamber is provided with an independent flow channel. This arrangement allows for the classified storage of solder paste of different models, specifications or brands within the same storage cabinet, achieving zoned management and preventing interference between them.

[0043] Example 2, please refer to Figures 4 to 5 A solder paste storage cabinet is described in this embodiment, which further optimizes the flow channel based on the first embodiment.

[0044] To prevent the solder paste can from tilting during rolling and to guide it to roll along a predetermined path center, a first protruding ridge 4 and a second protruding ridge 5 are provided in the middle of the inner bottom surface of the guide channel, along its entire path. The first protruding ridge 4 and the second protruding ridge 5 are spaced apart along the width direction of the guide channel, together forming a guide groove.

[0045] In other words, the inclined upper surfaces of the first inclined guide plate 2 and the second inclined guide plate 3 are provided with a first protruding ridge 4 and a second protruding ridge 5 along the length direction.

[0046] In specific manufacturing, an upward-facing U-shaped plate can be provided on the inclined upper surface of the first inclined guide plate 2 and the second inclined guide plate 3, and the two side walls of the U-shaped plate are respectively formed with a first protruding ridge 4 and a second protruding ridge 5.

[0047] Preferably, the top of the first convex ridge 4 is higher than the top of the second convex ridge 5, forming an asymmetrical structure that can better adapt to the shape and rolling characteristics of the solder paste can.

[0048] To cushion the impact and noise generated when the solder paste can rolls and changes direction, and to protect it from damage, a buffer strip 6 can be fitted onto the top of both the first convex ridge 4 and the second convex ridge 5. This buffer strip 6 can be made of materials with elastic and damping properties, such as rubber, silicone, or foam.

[0049] Example 2, please refer to Figure 6 and Figure 7 A solder paste storage cabinet, based on Embodiment 1, has an inlet 11 located on the front side of the top of the cabinet body 1. Additionally, a handle 7 can be installed in the middle of the front side wall of the cabinet body 1 for easy handling of the entire storage cabinet.

[0050] The working principle of this invention is as follows: the user inserts the solder paste container into the top inlet 11. Under the action of gravity, the solder paste container slowly rolls along a meandering channel formed by the alternation of the first inclined guide plate 2 and the second inclined guide plate 3. The protruding ribs on both sides serve to guide and prevent side slippage, while the buffer strips on them serve to reduce shock and noise. The solder paste container eventually rolls to the bottom front outlet 12, where the user can easily reach out and remove it from the recessed notch 15. When multiple types of solder paste need to be stored, they can be divided into multiple chambers by the partition 16 for classified storage. The user can observe the internal condition at any time through the viewing holes 13 on both sides and the viewing slots 14 on the front and back sides.

[0051] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims within this utility model.
