Description

Technical Field

[0001] The invention relates to the technical field of solder paste storage, in particular to a first-in-first-out solder paste storage device. Background Art

[0002] Solder paste is a commonly used auxiliary welding material in the field of electronic welding. It is mainly composed of tin and some flux. It is usually a paste. Generally, solder paste is often bottled or contained in syringes. In actual situations, SMT factories mostly purchase bottled solder paste. The solder paste needs to be kept at a low temperature when stored. When used, it needs to be warmed up for about 4-8 hours in an unopened state to ensure that the temperature of the solder paste returns to the natural ambient temperature to avoid condensation of water vapor in the air and entering the solder paste due to temperature difference. Only then can it be stirred to mix the flux and tin powder evenly to achieve a good use effect. The solder paste should not be frequently warmed up during storage, which will easily make the solder paste lose its activity. Even if the solder paste is well preserved, its shelf life is short. Therefore, when taking solder paste, it is usually taken according to the first-in-first-out principle.

[0003] When solder paste is stored, it is usually stored in a freezer or refrigerator. The existing upright refrigerator or freezer can meet the needs of storing solder paste. The suitable storage temperature range of some solder paste is 2°C to 10°C, which is a small range. The direct cooling refrigerator uses a compressor for refrigeration, which has a faster refrigeration effect and can usually achieve more precise temperature control. It is usually used to store solder paste. However, the temperature distribution inside the direct cooling refrigerator is uneven. Since the evaporator is generally located on the back plate of the refrigerator, there is more cold air near the inner wall of the refrigerator and the temperature is lower. In addition, whether it is a direct cooling refrigerator, the temperature distribution inside the refrigerator is uneven. Whether it is a refrigerator or an air-cooled refrigerator, it is generally a single-door or double-door design. When the solder paste is frequently taken out and the refrigerator door is frequently opened, the external heat is easy to affect the internal temperature of the refrigerator and affect the storage of the solder paste. It is particularly obvious in the summer when the temperature difference between the inside and outside of the refrigerator is high, which is more inconvenient. In addition, when taking the solder paste, the first-in-first-out principle is generally followed. The solder paste needs to be marked, and the person who takes it needs to manually find the information to identify it before taking it. When placing solder paste in the refrigerator, the solder paste is usually stacked on the refrigerator shelf in order. The separation between the solder pastes is not obvious, and it is easy to take it by mistake when taking it, which is more inconvenient. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The solder paste is arranged in sequence and placed into the rubber tubes of multiple storage mechanisms from the upper entrance in sequence. When storing, the multiple storage mechanisms can be driven to rotate by the rotating mechanism to replace the storage mechanism at the entrance, so that the solder paste is stored in sequence by the multiple storage mechanisms, and the multiple storage mechanisms are arranged in sequence from bottom to top inside the cabinet. When users take the solder paste, they can take out the stored solder paste in sequence from the lower exit, so that the solder paste can be taken in sequence according to the first-in-first-out principle, and the order of storing the solder paste can be clearly defined through the rubber tube, which is convenient for users to take, and the temperature in the rubber tube is relatively uniform through the rotating mechanism and the storage mechanism, which is convenient for solder paste storage, and when users take the solder paste, the internal temperature of other storage mechanisms located above the exit is not easily affected by the outside world.

[0021] 2. The user drives the transmission belt to rotate by rotating the roller, so that the transmission belt drives multiple storage mechanisms to move. When the storage mechanism moves to the entrance or exit, the slider on the storage mechanism is stuck in the guide rail and is in an expanded state. The user can pull out the rubber tube from the entrance or exit, straighten the rubber tube, and then pull the adjacent pull rod to slide on the adjacent limit rope. Then the user can insert the solder paste into the rubber tube or take it out in sequence. If the amount to be taken out or put in is large, the magnetic strip on the rubber tube can be pulled open and the solder paste can be put in or taken out from the cutting seam. Since the inner diameter of the rubber tube is similar to that of the solder paste box, the solder paste in the rubber tube will be arranged in sequence, which is convenient for the user to take in sequence;

[0022] 3. The user can rotate the handle to drive the transmission belt through the roller, so that the transmission belt pulls multiple storage mechanisms to move. The multiple storage mechanisms on one side of the transmission belt can pull the two plates on the storage mechanism away from each other, so that the limit rope and the support cloth between the two plates are straightened and in an expanded state, while the storage mechanism on the other side of the transmission belt can move the two plates on the storage mechanism toward each other, so that the plates squeeze the rubber tube and other rubber products to stack them and are in a storage state. The rubber tube in the storage mechanism in the expanded state can be moved by the transmission belt to align with the duct and the air guide hole group, so that the air pump in the duct inputs the colder air in the fixed shell into the rubber tube through the duct and the air outlet, and discharges it back into the fixed shell through the air guide hole group, so that the overall temperature inside the rubber tube is relatively uniform, and when the cabinet door is opened and closed, because the two ends of the rubber tube are connected with the duct and the inside of the fixed shell in a relatively closed state, the rubber tube itself has a certain heat preservation effect, so that the external temperature is not easy to affect the internal temperature of the rubber tube;

[0023] 4. When the sliding block on the storage mechanism is driven out of the guide rail by the rotating mechanism, the electric push rod on the adjacent resistance mechanism can be started to push the adjacent push block to slide along the adjacent rail. The user can manually assist the push rod on the storage mechanism to be inserted into the push block, so that the push block drives the push rod to move, and the moving push block makes the two plates approach or move away through the push rod, which is convenient for the user to unfold or store the storage mechanism.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 10 In an embodiment of the present invention, a first-in-first-out solder paste storage device includes:

[0037] A cabinet 100 for refrigerating and storing solder paste, a thermal insulation frame 200, a storage mechanism 300 for storing boxed solder paste, a rotating mechanism 400 and two driving mechanisms 500 for adjusting the positions of multiple storage mechanisms 300, the cabinet 100 is a one-side open structure, the thermal insulation frame 200 is fixedly connected to one side of the cabinet 100, and the interior of the thermal insulation frame 200 is connected to the interior of the opening on one side of the cabinet 100, an insulation board 210 is fixedly sleeved on the inner wall of the insulation frame 200, and connecting ports 211 are opened at both the top and bottom ends of one side of the insulation board 210, two closed doors 201 for closing the two connecting ports 211 are rotatably connected at one long side of the insulation frame 200, and the two closed doors 201 are respectively located at the two connecting ports 211, and multiple storage mechanisms 300 arranged vertically in sequence are Located inside the cabinet 100, the storage mechanism 300 includes two plate bodies 310, wherein a fixing rod 311 is fixedly connected to the center of one side of one plate body 310, a support cloth 320 is fixedly connected between the bottom surfaces of the two plate bodies 310, and a rubber tube 330 is arranged above the support cloth 320, one end of the rubber tube 330 is fixedly sleeved with a positioning ring 340, and the outer wall of the positioning ring 340 is fixedly connected to a long side edge of the top surface of the support cloth 320, a circular hole is opened at one end of one side of one plate body 310, and the rubber tube 330 is movably inserted into the circular hole, the rotating mechanism 400 is located inside the cabinet 100, and the rotating mechanism 400 is fixedly connected to one end of the fixing rods 311 on multiple storage mechanisms 300, and two driving mechanisms 500 are respectively located at the top and bottom ends of the inside of the cabinet 100.

[0038] Specifically, the cabinet 100 is an existing vertical direct cooling refrigerator or freezer. When installing, the shelves and cabinet doors in the original vertical refrigerator are removed, and then the insulation frame 200 is bonded to the original cabinet door, and then the insulation board 210 is bonded or welded to the inside of the insulation frame 200. The insulation frame 200 and the insulation board 210 are both made of insulation materials. The closed door 201 can use an existing refrigerator cabinet door with a door seal. The upper communication port 211 of the two communication ports 211 is an entrance for putting solder paste, and the upper communication port 211 is located at the bottom. The lower connecting port 211 is an outlet for taking out solder paste. When in use, solder paste is sequentially inserted into the rubber tube 330 on the storage mechanism 300 through the entrance according to data such as batch and production date, so that the solder paste to be used first enters into one rubber tube 330 for storage, and then the rotating mechanism 400 drives the multiple storage mechanisms 300 to rotate as a whole, so that one rubber tube 330 moves downward, and another rubber tube 330 moves to the entrance, and then the solder paste of the subsequent date is inserted into another rubber tube 330. All solder pastes are stored in the multiple rubber tubes 330 in sequence, and the rubber tube 330 located at the bottom in the cabinet 100 stores the solder paste that enters first, and the rubber tube 330 located at the top stores the solder paste that enters later. When taking solder paste, the solder paste is taken through the outlet, which can be first in first out. After the rubber tube 330 is filled with solder paste, the other end of the rubber tube 330 can be manually clamped in the circular hole on the adjacent plate 310, so that the openings at both ends of the rubber tube 330 are close to the rotating mechanism 400, so that when taking solder paste, ... When the solder paste is opened and closed, the other rubber tubes 330 above the outlet are in a relatively closed state, reducing the influence of the opening and closing door on the rubber tube 330 above the outlet, making the temperature change in the rubber tube 330 above the outlet smaller, thereby facilitating the storage of solder paste, and when inserting the solder paste, the rubber tubes 330 are inserted in sequence, and the diameter of the rubber tube 330 is similar to that of the solder paste box, so that the solder paste in the rubber tube 330 can be arranged in sequence inside the rubber tube 330, which is convenient for users to take the solder paste in sequence.

[0039] Embodiment 1

[0040] like Figure 4-Figure 8As shown, in this embodiment, a cutting slit is provided at the top of the outer wall of any rubber tube 330, and a magnetic strip 331 is fixedly connected to the two inner walls of any cutting slit, and the two magnetic strips 331 inside the same cutting slit are mutually attracted and movably connected, and a plurality of pull rods 350 are provided on the adjacent sides of the two plate bodies 310 on any storage mechanism 300, and both ends of any pull rod 350 are fixedly connected to an elastic rope 351, and one end of any elastic rope 351 is fixedly connected to the side wall of the adjacent plate body 310, and the two plate bodies 310 on any storage mechanism 300 are fixedly connected to the two plate bodies 310. The multiple pull rods 350 are arranged in a staggered manner, and holes are provided at both ends of the top and bottom of the outer wall of any pull rod 350 in any storage mechanism 300. A limit rope 360 ​​is slidably sleeved inside any hole, and any limit rope 360 ​​is fixedly connected between two adjacent plates 310. An arc-shaped card shell 312 is fixedly sleeved inside a circular hole on a plate body 310 in any storage mechanism 300, and a rubber clamping ring 332 is fixedly sleeved at the other end of any rubber tube 330, and any rubber clamping ring 332 is movably clamped inside the adjacent arc-shaped card shell 312.

[0041] In this embodiment, when the solder paste is stored, the user can manually pull the rubber tube 330 so that one end of the rubber tube 330 is pulled out of the entrance, and the rubber tube 330 is straightened so that the straightened rubber tube 330 can pull the adjacent pull rod 350 to slide along the adjacent limit rope 360, and then the user can sequentially insert the solder paste into the rubber tube 330. If the amount of solder paste stored is large, the user can use a tool to pry open the magnetic strips 331 on the rubber tube 330 that are clamped together and adsorbed to each other, and then manually arrange the solder paste into the rubber tube 330 in sequence, and then use pliers or other items to close and clamp the two magnetic strips 331, and then insert the rubber tube 330 back into the entrance. At this time, the pull rod 350 that was originally straightened by the rubber tube 330 and driven to move is It will be driven by the reset elastic force of the adjacent elastic rope 351 to slide and reset along the adjacent limit rope 360, so that the reset pull rod 350 pulls the rubber tube 330 to a serpentine state, thereby automatically storing the rubber tube 330, and then the user inserts the other end of the rubber tube 330 into the circular hole on the adjacent plate body 310, and by installing an arc-shaped card shell 312 in the circular hole and installing a rubber clamping ring 332 on the rubber tube 330, the rubber clamping ring 332 is inserted into the arc-shaped card shell 312, thereby improving the fixing effect of the other end of the rubber tube 330. The rubber tube 330 is thicker and can have a heat-insulating effect. When pulled to the serpentine state by the pull rod 350, the pull rod 350 is not easy to squeeze the rubber tube 330 to produce a depression due to the elastic force generated by the thicker inner wall of the rubber tube 330.

[0042] like Figure 3-Figure 4As shown, in this embodiment, an inner wall of the cabinet 100 is fixedly connected to a guide rail 301, and a slider 370 is fixedly connected to the center of one side of another plate 310 on any storage mechanism 300. Any slider 370 is movably clamped inside the guide rail 301, and any slider 370 is provided with a movable wheel.

[0043] During specific implementation, since the rubber tube 330, the support cloth 320, the limiting rope 360, the elastic rope 351, the positioning ring 340, the rubber clip 332, etc. are all soft items, the two plates 310 on the storage mechanism 300 can be manually moved toward each other to squeeze the rubber tube 330 and other items between them, so that they are folded and stored. When the storage mechanism 300 is in use, the two plates 310 can be manually pulled away from each other to make the support cloth 320 naturally unfold and straighten multiple limiting ropes 360, while other rubber products such as the rubber tube 330, rubber clip 332, positioning ring 340, etc. will naturally recover due to their own elastic force, and then the other plate 310 on the storage mechanism 300 will be stuck into the guide rail 301, so that the guide rail 301 can limit the position of the other plate 310, so that the two plates 310 remain in the unfolded state, and the moving wheel facilitates the movement of the slider 370 inside the guide rail 301.

[0044] like Figure 3 and Fig. 9 As shown, in this embodiment, the rotating mechanism 400 includes:

[0045] A frame 410, two rollers 420, a transmission belt 430, a plurality of conduits 440 and a fixed shell 450, one side of the frame 410 is fixedly connected to the other inner wall of the cabinet 100, the two rollers 420 are rotatably connected between the two opposite inner walls of the frame 410, wherein one end of the roller shaft of one roller 420 passes through one side of the frame 410 and is fixedly connected with a handle, the transmission belt 430 is rotatably sleeved between the outer walls of the two rollers 420, the outer wall of the transmission belt 430 is fixedly connected to one end of the fixed rods 311 on the plurality of storage mechanisms 300, the plurality of conduits 440 are all located inside the frame 410, the plurality of conduits 440 are arranged vertically in sequence, and one end of the plurality of conduits 440 passes through the other side of the frame 410, the other ends of the plurality of conduits 440 are all against the inner wall of the transmission belt 430, the transmission belt 430 A plurality of air outlet holes are provided on the inner wall, and a rubber ring 313 is fixedly sleeved on the circular hole of a plate body 310 in any storage mechanism 300, one side of the fixed shell 450 is fixedly connected to the inner wall of the cabinet 100, and the other side of the fixed shell 450 is fixedly connected to one end of a plurality of conduits 440, and the interiors of the plurality of conduits 440 are connected to the interior of the fixed shell 450, and a plurality of air guide hole groups are equidistantly provided on the other side of the fixed shell 450, and the air guide hole group includes a plurality of evenly arranged air guide holes, and an air pump is arranged inside any conduit 440, a plurality of annular iron wires 431 are fixedly sleeved on the inner wall of the transmission belt 430, the outer walls of the two rollers 420 are coated with a rubber layer, and a plurality of annular grooves are provided on the rubber layer on the outer walls of the two rollers 420, and the plurality of iron wires 431 are movably clamped in adjacent annular grooves.

[0046] In specific implementation, the temperature of the inner wall of the refrigerator is the lowest. During installation, the fixed shell 450 is connected to the inner wall of the refrigerator so that the cold air generated by the inner wall of the refrigerator is concentrated inside the fixed shell 450. The multiple storage mechanisms 300 on the outer wall of the transmission belt 430 are evenly distributed. The distance between two adjacent storage mechanisms 300 is equal to the distance between two adjacent ducts 440. The user can manually hold the handle to drive the adjacent rollers 420 to rotate, and the rollers 420 drive the transmission belt 430 to rotate, so that the transmission belt 430 pulls the adjacent storage mechanism 300 to move, driving the storage mechanism The slider 370 on the structure 300 slides in the guide rail 301 or on the cabinet wall, and the positions of the multiple storage mechanisms 300 are adjusted so that the other end opening of each conduit 440 is aligned with the other end opening of the rubber tube 330 on the adjacent storage mechanism 300 and is inserted into the arc-shaped card shell 312, and the opening of one end of the rubber tube 330 is limited by the adjacent positioning ring 340 and naturally abuts on the other side of the fixed shell 450, so that the inside of the rubber tube 330 is connected to the inside of the fixed shell 450 through the air guide holes on the air guide hole group, and the rubber ring 313 on the storage mechanism 300 is closely attached to the transmission When the conduit 440 is aligned with the adjacent rubber ring 313, the air pump is started to suck the cooler air inside the fixed shell 450 and enter the rubber tube 330 through the air outlet holes on the conduit 440 and the transmission belt 430 to cool the solder paste inside the rubber tube 330. Then the cooler air is discharged back to the fixed shell 450 from the air guide hole, so that the overall temperature inside the rubber tube 330 is relatively uniform. The air pump is a prior art and will not be described in detail here. In addition, due to the heat preservation effect of the rubber tube 330, the external temperature is not easily affected by the frequent opening and closing of the door. The internal temperature is increased by the iron wire 431 to increase the carrying capacity of the transmission belt 430, and the iron wire 431 is stuck in the annular groove on the roller 420 to limit the transmission belt 430 and prevent it from deviating. In the storage mechanism 300 located between the transmission belt 430 and the other inner wall of the cabinet 100 and in the storage state, the rubber parts such as the rubber tube 330 squeezed between the two plate bodies 310 have the resilience to squeeze the adjacent plate bodies 310, so that the slider 370 on the plate body 310 can be close to the inner wall of the cabinet body 100, thereby using the pulley on the slider 370 to move on the cabinet wall.

The electric push rods 510 on the two driving mechanisms 500 are respectively located at the top and bottom ends of the other side of the fixed shell 450. The rail 520 is located at the other side of the fixed shell 450. The rails 520 on the two driving mechanisms 500 are respectively fixedly connected to the top and bottom surfaces inside the cabinet 100, and the two rails 520 are both slidably connected with blocks 521 inside. One side of the two blocks 521 is fixedly connected with a shift block 522 through a connecting rod, and the two shift blocks 522 are both arc-shaped. The two shift blocks 522 are diagonally arranged with the center of the cabinet 100 as the center, and the slider 370 in any storage mechanism 300 is fixedly connected with a shift rod 371 at both ends.

[0051] During specific implementation, the two connecting ports 211 on the insulation board 210 are respectively located at the top and bottom of the guide rail 301, so that the storage mechanism 300 for putting solder paste in through the entrance and the storage mechanism 300 for taking out solder paste through the exit are both kept in an expanded state due to the slider 370 being stuck in the guide rail 301. When the storage mechanism 300 needs to be stored or expanded, the slider 370 on the storage mechanism 300 can be driven to disengage from the guide rail 301 by rotating the transmission belt 430, so that the lever 371 falls on the adjacent lever block 522. The user can manually assist the lever 371 to align with the lever block 522, and then start the electric push rod 510 to move the adjacent lever block 522 along the adjacent clamping rail 520, so that the lever block 522 pushes the two plate bodies 310 closer or farther away, so as to facilitate the user to squeeze or pull apart the two plate bodies 310 on the storage mechanism 300, which is convenient for the user to use.
