Description

Technical Field

[0001] This utility model relates to the field of solder bar storage technology, and in particular to a lead-free solder bar storage device. Background Technology

[0002] In the fields of electronic manufacturing, circuit repair and precision instrument assembly, soldering is the core process for achieving a stable connection between electronic components and circuit boards. Solder bars, as a key consumable in the soldering process, directly determine the soldering quality and the service life of electronic equipment.

[0003] In actual production or maintenance scenarios, the number of solder bars of different specifications often varies significantly. However, existing storage devices mostly use fixed partitions to divide storage areas, resulting in a fixed internal space that cannot be dynamically adjusted according to the amount used. This leads to a situation where specifications with high usage require additional storage devices due to insufficient partition space, while specifications with low usage have idle partition space, resulting in a waste of overall storage space. This increases storage costs and occupies too much workbench or warehouse space, thus limiting its use.

[0004] To address this, a lead-free solder bar storage device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a lead-free solder bar storage device that solves the problem that existing storage devices mostly use fixed partitions to divide storage areas, resulting in a fixed internal space that cannot be dynamically adjusted according to the amount of usage. This leads to a situation where high-volume specifications require additional storage devices due to insufficient partition space, while low-volume specifications have idle partition space, resulting in a waste of overall storage space, increased storage costs, and excessive occupation of workbench or warehouse space, thus limiting its use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lead-free solder bar storage device, comprising a storage box, wherein an adjustment mechanism is provided inside the storage box, the adjustment mechanism comprising a partition component and a positioning component, the partition component comprising a partition cavity, the number of partition cavities being set to multiple and the partition cavities being disposed inside the storage box, the front and rear sides of the inner wall of the storage box being provided with transverse grooves, a crossbar being fixedly connected inside the transverse grooves, a rectangular frame being slidably connected to the surface of the crossbar and the rectangular frame being fixedly connected to the partition cavity, and silicone plates being adhered to both sides of the partition cavity.

[0007] Preferably, the positioning component includes a positioning rod that penetrates the partition cavity and extends into the interior of the rectangular frame. Two positioning rods are fixedly connected to a triangular block at their adjacent ends. The surface of the crossbar has multiple slots that cooperate with the positioning rods. A first spring is sleeved on one end of the positioning rod inside the partition cavity. The two ends of the first spring are fixedly connected to the triangular block and the inner wall of the partition cavity, respectively.

[0008] Preferably, a pressing block is provided between the two triangular blocks on opposite sides, the pressing block having an inclined surface on the side closest to the triangular blocks, and a moving rod fixedly connected to the top of the pressing block, the moving rod passing through the partition cavity.

[0009] Preferably, a second spring is sleeved at one end of the movable rod located in the partition cavity, and the two ends of the second spring are fixedly connected to the extrusion block and the interior of the partition cavity, respectively. The elastic force of the second spring is greater than that of the first spring.

[0010] Preferably, a U-shaped frame is fixedly connected to the left side of the partition cavity, and a connector is rotatably connected inside the U-shaped frame via a bearing. A sealing top plate is fixedly connected to the surface of the connector, and the sealing top plate is used in conjunction with the storage box.

[0011] Preferably, a metal block is installed inside the bottom of the sealed top plate, and a magnetic block that is magnetically connected to the metal block is provided inside the top of the storage box.

[0012] Preferably, the bottom of the sealing top plate is provided with a placement groove, the interior of the placement groove is provided with a movable frame, the bottom of the inner wall of the movable frame is fixedly connected with a placement net, the top of the placement net is provided with a desiccant plate, the inner walls of the placement groove are provided with limit grooves on both sides, and the movable frame is fixedly connected with limit blocks that cooperate with the limit grooves on both sides.

[0013] Preferably, a fixing plate is fixedly connected to the outer side of the movable frame, and the fixing plate is bolted to the sealing top plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a partition component, allows multiple partition cavities within the storage box to classify and store lead-free solder bars of different specifications. The partition cavities are slidably connected to the crossbar via a rectangular frame, and can move left and right within the storage box. The space size of each partition cavity can be flexibly adjusted according to the actual quantity and specifications of the solder bars stored, solving the problem of the inflexible space adjustment of existing storage devices and improving the space utilization of the storage box. At the same time, the silicone plates on both sides of the partition cavities can play a buffering and protective role, preventing the solder bars from being damaged by collisions during storage.

[0016] 2. This application, by setting a positioning component, allows the partition cavity to be positioned when the position needs to be adjusted. Pulling the moving rod upward causes the squeezing block to move upward, thereby releasing the squeezing block from the two triangular blocks. This allows the positioning rod to overcome the elastic force of the first spring and be pulled out of the slot, enabling the partition cavity to slide. Since the elastic force of the second spring is greater than that of the first spring, after releasing the moving rod, the squeezing block will move downward under the action of the second spring to continue squeezing the two triangular blocks, causing the positioning rod to re-insert into the slot, thus achieving the positioning of the partition cavity. The operation is convenient and quick. Attached Figure Description

Detailed Implementation

[0023] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A lead-free solder bar storage device includes a storage box 1. An adjustment mechanism 2 is provided inside the storage box 1. The adjustment mechanism 2 includes a partition component 21 and a positioning component 22. The partition component 21 includes a partition cavity 211. The number of partition cavities 211 is set to multiple and the partition cavities 211 are located inside the storage box 1. A transverse groove 3 is provided on the front and rear sides of the inner wall of the storage box 1. A crossbar 212 is fixedly connected inside the transverse groove 3. A rectangular frame 213 is slidably connected to the surface of the crossbar 212 and is fixedly connected to the partition cavity 211. Silicone plates 214 are glued to both sides of the partition cavity 211.

[0026] In this embodiment: By setting the separator component 21, the separator cavity 211 is used to classify and store lead-free solder bars of different specifications, realizing the orderly separation of solder bars and avoiding confusion caused by mixed storage. The transverse groove 3 is opened on the front and rear sides of the inner wall of the storage box 1, which can provide installation space for the crossbar 212, and at the same time guide the sliding of the rectangular frame 213, ensuring that the separator cavity 211 moves smoothly along a fixed trajectory. The crossbar 212 is the sliding track of the rectangular frame 213, which can support the separator cavity 211 and restrict its movement direction, ensuring that the positions of multiple separator cavities 211 can be adjusted. To ensure stability, the rectangular frame 213 is fixedly connected to the partition cavity 211 and sleeved on the surface of the crossbar 212. It can slide along the crossbar 212, driving the partition cavity 211 to move synchronously, thus realizing flexible adjustment of the space size between the cavities. The silicone plate 214 is bonded to both sides of the partition cavity 211, which has elasticity and buffering effect. On the one hand, it can reduce the hard friction between adjacent cavities when the partition cavity 211 moves or is hit by external force. On the other hand, it can avoid scratches caused by direct contact between the solder bar and the side wall of the partition cavity 211, while enhancing the clamping stability of the internal solder bar.

[0027] Specifically, such as Figure 5 As shown, the positioning component 22 includes a positioning rod 221, which passes through the partition cavity 211 and extends into the interior of the rectangular frame 213. A triangular block 222 is fixedly connected to one end of each of the two positioning rods 221 that are close to each other. A plurality of slots 223 are provided on the surface of the crossbar 212 and the slots 223 cooperate with the positioning rods 221. A first spring 224 is sleeved on one end of the positioning rod 221 inside the partition cavity 211. The two ends of the first spring 224 are fixedly connected to the triangular block 222 and the inner wall of the partition cavity 211, respectively.

[0028] Specifically, such as Figure 5 As shown, a pressing block 225 is provided between the opposite sides of the two triangular blocks 222. The side of the pressing block 225 near the triangular blocks 222 is set as an inclined surface. A moving rod 226 is fixedly connected to the top of the pressing block 225 and the moving rod 226 passes through the partition cavity 211.

[0029] Specifically, such as Figure 5 As shown, a second spring 227 is sleeved on one end of the moving rod 226 located in the partition cavity 211. The two ends of the second spring 227 are fixedly connected to the pressing block 225 and the interior of the partition cavity 211, respectively. The elastic force of the second spring 227 is greater than that of the first spring 224.

[0030] In this embodiment: by setting the positioning component 22, the positioning rod 221 can be inserted into the slot 223 on the surface of the crossbar 212. The sliding of the rectangular frame 213 and the partition cavity 211 is restricted by mechanical engagement, thereby fixing the position of the partition cavity 211. The first spring 224 is sleeved on the end of the positioning rod 221 located inside the partition cavity 211. In its natural state, the first spring 224 is compressed by the triangular block 222, allowing the positioning rod 221 to be inserted into the slot 223 and maintain its positioning state. When the moving rod 226 is pulled upward, the compressed elastic force of the first spring 224 is released, thereby driving the positioning rod 221 out of the slot 223, releasing the positioning effect of the positioning rod 221 on the partition cavity 211. The pressing block 225 is located between the two triangular blocks 222, with inclined surfaces on both sides. In the initial state, the inclined surfaces of the pressing block 225 will push the triangular blocks 222 to drive the positioning rod 221 to move laterally, thereby realizing the extension and retraction of the rod. 23 can cooperate with the positioning rod 221 to form a positioning point. By selecting different slots 223, the partition cavity 211 can be fixed in different positions to meet different space adjustment needs. By setting the moving rod 226, pulling the moving rod 226 upward can drive the pressing block 225 to move upward, so that the unlocking action of the positioning rod 221 can be triggered. The second spring 227 has a greater elastic force than the first spring 224. In its natural state, it can push the pressing block 225 downward to press the two triangular blocks 222, so that the triangular blocks 222 drive the positioning rod 221 to insert into the slot 223 and maintain the positioning state of the partition cavity 211. When the moving rod 226 is moved upward, it can drive the pressing block 225 to move upward until the pressing block 225 is away from the triangular block 222, releasing the pressing effect on the triangular block 222. This allows the two triangular blocks 222 to be disengaged from the slot 223 under the return force of the first spring 224, thus releasing the positioning effect on the partition cavity 211.

[0031] Specifically, such as Figure 1 As shown, a U-shaped frame 4 is fixedly connected to the left side of the partition cavity 211. A connector 5 is rotatably connected inside the U-shaped frame 4 via a bearing. A sealing top plate 6 is fixedly connected to the surface of the connector 5. The sealing top plate 6 is used in conjunction with the storage box 1.

[0032] Specifically, such as Figure 1 As shown, a metal block 7 is installed inside the bottom of the sealed top plate 6, and a magnetic block 8 that is magnetically connected to the metal block 7 is installed inside the top of the storage box 1.

[0033] In this embodiment: With the above settings, the U-shaped frame 4 is fixedly connected to the left side of the partition cavity 211, serving as the supporting base for the sealing top plate 6. It can provide a stable mounting carrier for the connector 5. The connector 5 is rotatably connected to the U-shaped frame 4 through a bearing, which can form a movable connection between the sealing top plate 6 and the U-shaped frame 4, allowing the sealing top plate 6 to flexibly rotate around the connection point, realizing the opening and closing of the storage box 1. The sealing top plate 6 works in conjunction with the storage box 1. When closed, it can cover the opening of the storage box 1, forming a closed space, effectively blocking external dust and impurities from entering the interior of the storage box 1, and protecting the lead-free solder bar from contamination. The metal block 7 is installed inside the bottom of the sealing top plate 6, serving as a magnetic adsorption component. It can generate an adsorption force with the metal block 7 inside the sealing top plate 6 through magnetism, so that the sealing top plate 6 can tightly fit the storage box 1 in the closed state, thereby enhancing the sealing effect. Compared with traditional mechanical latches, the magnetic connection structure is easier to operate, and opening and closing do not require additional unlocking steps. At the same time, it can ensure that the sealing top plate 6 will not be accidentally opened under non-human operation.

[0034] Specifically, such as Figure 4 As shown, a placement groove 9 is provided at the bottom of the sealing top plate 6. A movable frame 10 is provided inside the placement groove 9. A placement net 11 is fixedly connected to the bottom of the inner wall of the movable frame 10. A desiccant plate 12 is provided at the top of the placement net 11. Limiting grooves 13 are provided on both sides of the inner wall of the placement groove 9. Limiting blocks 14 that cooperate with the limiting grooves 13 are fixedly connected to both sides of the movable frame 10.

[0035] Specifically, such as Figure 4 As shown, a fixing plate 15 is fixedly connected to the outer side of the movable frame 10, and the fixing plate 15 is bolted to the sealing top plate 6.

[0036] In this embodiment: With the above configuration, the placement slot 9 is located at the bottom of the sealed top plate 6, providing installation space for the movable frame 10 and forming an independent moisture-proof unit accommodating area. The movable frame 10 serves as the supporting frame for the desiccant plate 12, integrating the desiccant plate 12, placement net 11, and other components into a single movable module, facilitating the replacement and maintenance of the desiccant plate 12. Its outline matches the placement slot 9, ensuring the moisture-proof structure can be stably installed within the placement slot 9. The placement net 11 is fixed to the bottom of the inner wall of the movable frame 10 to support the desiccant plate 12. Simultaneously, its mesh structure allows air circulation, enabling the desiccant plate 12 to fully contact the air inside the storage box 1, thus absorbing moisture and preventing dampness. The desiccant plate 12 is made of silica gel desiccant or other moisture-absorbing materials, which can absorb moisture in the storage box 1, reduce internal humidity, prevent lead-free solder bars from oxidizing and deteriorating due to moisture, and extend their shelf life. The limiting groove 13 can provide a guide and constraint track for the limiting block 14, ensuring that the moving frame 10 moves smoothly in and out of the placement groove 9, preventing the moving frame 10 from shifting or shaking during assembly or use, and ensuring structural stability. The fixing plate 15 can be bolted to the sealing top plate 6 to firmly lock the moving frame 10 in the placement groove 9, preventing the moving frame 10 from falling off accidentally. At the same time, the detachable bolted structure makes it easy to disassemble the moving frame 10 later to replace the desiccant plate 12, taking into account both the reliability of fixing and the convenience of maintenance.

[0037] Working principle: First, flip the sealing top plate 6 upwards, causing it to rotate around the U-shaped frame 4. The metal block 7 separates from the magnetic block 8, opening the storage box 1. If it is necessary to adjust the internal space of the partition cavity 211, pull the moving rod 226 of the target partition cavity 211 upwards. When the moving rod 226 moves upwards, it will drive the pressing block 225 at its bottom to move upwards simultaneously. At this time, the pressing block 225 will disengage from the inclined surfaces of the triangular blocks 222 on both sides, no longer applying pressure to the triangular blocks 222. The originally compressed space... The first spring 224 will recover its elastic deformation, generating an outward pushing force that pushes the triangular block 222 and the positioning rod 221 to move synchronously, causing the positioning rod 221 to be pulled out of the slot 223 on the surface of the crossbar 212, releasing the restriction on the rectangular frame 213 and the partition cavity 211. At this time, the partition cavity 211 can slide freely along the crossbar 212. Then, the rectangular frame 213 slides along the crossbar 212 to the desired position. Then, the moving rod 226 is released, so that the downward restoring force of the second spring 227 will drive the squeeze... As the pressure block 225 moves downward, its inclined surface pushes the triangular block 222, causing the positioning rod 221 to move laterally. This allows the positioning rod 221 to re-insert into the corresponding slot 223, thus completing the positioning of the partition cavity 211. Repeat the above operation to adjust other partition cavities 211 and divide the storage space to accommodate different specifications of solder bars. Then, place the lead-free solder bars of different specifications into the corresponding partition cavities 211, and then flip the sealing top plate 6 downward to cover the opening of the storage box 1. The metal block 7 will magnetically attract the magnetic block 8 to achieve a sealed fixation. The desiccant plate 12 inside the sealed top plate 6 circulates with the air inside the storage box 1 through the placement net 11, which can absorb moisture and keep it dry. When the desiccant plate 12 is saturated with moisture, unscrew the bolts connecting the fixing plate 15 and the sealed top plate 6, pull out the moving frame 10 along the limiting groove 13, replace the desiccant plate 12 on the top of the placement net 11, reset the moving frame 10 through the limiting block 14 and the limiting groove 13, and re-bolt the fixing plate 15 to complete the replacement.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
