Abstract
Description
Technical Field
[0001] This utility model relates to the field of flux production technology, and more specifically, to a paste flux rolling and feeding device. Background Technology
[0002] In many fields such as electronics manufacturing and welding processes, paste flux plays an indispensable role as a key auxiliary material. It can effectively remove oxides from the metal surface and reduce the surface tension of the solder during the welding process, thereby improving the quality and reliability of the welding and ensuring that the weld joint has good conductivity and mechanical strength.
[0003] A search revealed that Chinese Patent Publication No. CN222683696U discloses a "Paste Flux Rolling and Discharging Device, comprising a mounting frame, a rolling device, a reciprocating moving device, a feeding hopper, and a scraping device, wherein an inclined feeding plate is provided at the bottom of the mounting frame; the rolling device is disposed within the mounting frame; the reciprocating moving device is disposed above the rolling device; the feeding hopper is disposed on the moving end of the reciprocating moving device; and the scraping device is disposed between the rolling device and the feeding plate. This utility model, by placing the feeding hopper on the moving end of the reciprocating moving device, enables the feeding hopper to move with the reciprocating moving device and pour the paste flux onto the rolling device, resulting in better continuity and effectiveness. Furthermore, the scraping device on the feeding plate can automatically scrape off the paste flux on the feeding plate, reducing manual operation and increasing efficiency." However, it still has the following drawbacks:
[0004] When using this device, the viscosity and flowability of the paste flux vary, resulting in significant fluctuations in its flow rate and quantity under different ambient temperatures and pressures. This leads to inconsistent flux amounts at each welding point during the welding process, potentially causing defects such as spatter and porosity in some welds due to excessive flux, thus affecting welding quality. Furthermore, the device cannot change the temperature of the paste flux, making it impossible to maintain suitable flowability and reducing product stability. Therefore, a paste flux compaction and feeding device is proposed. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] like Figure 1 and Figure 3 As shown, this embodiment proposes a paste flux rolling and feeding device, including a base 1, a feeding component 2 for uniformly rolling and feeding paste flux is provided on the top of the base 1, and a cleaning component 3 for cleaning the rolling position is provided on one side of the base 1.
[0029] like Figure 2 and Figure 3As shown, the feeding assembly 2 includes a first servo motor 201 bolted to one side of the base 1. The output end of the first servo motor 201 is equipped with a drive roller 202. A driven roller 203 is rotatably connected to the inner wall of the base 1. A first gear 204 and a second gear 205 are respectively provided at the ends of the drive roller 202 and the driven roller 203 away from the servo motor. The first gear 204 and the second gear 205 mesh with each other. The first servo motor 201 drives the drive roller 202 to rotate, and the first gear 204 and the second gear 205 drive the driven roller 203 to rotate, thus crushing the paste-like flux. A second servo motor 206 is bolted to one side of the base 1. A lead screw 207 is coaxially provided at the output end of the second servo motor 206. The outer wall of the lead screw 207 is threadedly connected to a discharge chamber 2. 08. A crossbar 209 is fixedly connected to the inner wall of the base 1. The second servo motor 206 drives the lead screw 207 to rotate, so that the paste flux in the discharge chamber 208 is evenly spread between the active roller 202 and the driven roller 203. A storage chamber 210 is fixedly connected to the top of the base 1. A resistance wire 211 is provided on the inner wall of the storage chamber 210. Heat is generated by energizing the resistance wire 211 in the storage chamber 210 to heat the paste flux in the storage chamber 210 at a low temperature, so that the paste flux maintains a suitable fluidity. A conveying pipe 212 is fixedly connected to the bottom of the storage chamber 210. The end of the conveying pipe 212 away from the storage chamber 210 is connected to the interior of the discharge chamber 208. A conveyor belt 213 is provided on the inner bottom wall of the base 1 to ensure the smooth conveying of the flux. The resistance wire 211 in the storage chamber 210 generates heat when energized, which heats the paste flux in the liquid storage chamber at a low temperature, keeping the paste flux with suitable fluidity. The paste flux is then transported to the discharge chamber 208 through the conveying pipe 212. The second servo motor 206 drives the lead screw 207 to rotate, causing the discharge chamber 208 to move reciprocally horizontally. As the discharge chamber 208 moves, the paste flux flows evenly from the discharge chamber 208 between the drive roller 202 and the driven roller 203. At the same time, the first servo motor 201 drives the drive roller 202 to rotate, and through cooperation with the driven roller 203, it crushes the spread paste flux, making it more evenly distributed. Finally, it falls onto the conveyor belt 213 to complete the feeding process. This not only makes the paste flux easier to spread evenly and reduces the difficulty of the process, but also avoids the flux solidifying due to excessively low temperature, which would affect the feeding process.
[0030] like Figure 4As shown, the cleaning component 3 includes a liquid storage frame 301 fixedly connected to one side of the base 1. A booster pump 302 is provided on the top of the liquid storage frame 301. A delivery pipe 303 is provided at the output end of the booster pump 302. A liquid outlet frame 304 is provided at the end of the delivery pipe 303 away from the booster pump 302. Multiple nozzles 305 are fixedly connected to one side of the liquid outlet frame 304. The booster pump 302 draws out the cleaning liquid from the liquid storage frame 301 and delivers it to the liquid storage frame 301 through the delivery pipe 303. The nozzles 305 then spray the cleaning liquid evenly onto the compaction area. When the rolling of the paste flux stops, the booster pump 302 draws cleaning fluid from the storage box 301, delivers it to the outlet box 304 through the delivery pipe 303, and finally sprays it out from multiple nozzles 305 to clean the positions of the drive roller 202 and the driven roller 203. The residual paste flux on the surface of the drive roller 202 and the driven roller 203 is completely removed, which improves the cleaning efficiency and reduces manual operation.
[0031] like Figure 4 As shown, two fixing plates 4 are fixedly connected to the inner wall of the base 1, and scrapers 5 are fixedly connected to the top of each fixing plate 4. When the drive roller 202 and the driven roller 203 rotate, the scrapers 5 on the top of the fixing plates 4 come into contact with their surfaces and scrape off the paste-like flux adhering to the surfaces of the drive roller 202 and the driven roller 203. This prevents flux residue from affecting the normal operation of the drive roller 202 and the driven roller 203 and the next rolling effect, ensuring that each rolling achieves a uniform effect and improving product quality.
[0032] like Figure 4 As shown, the outer wall of the conveyor belt 213 is provided with multiple partitions 6, which are evenly distributed along the length of the conveyor belt 213. During operation, the partitions 6 divide the surface of the conveyor belt 213 into multiple independent areas, each of which can hold a certain amount of flux paste, preventing the flux from sliding or accumulating during transport and ensuring the stability and uniformity of the transport.
[0033] like Figure 3 As shown, a connecting plate 7 is fixedly connected to one side of the base 1, and a clamp 8 is fixedly connected to one side of the connecting plate 7. The clamp 8 on the connecting plate 7 fixes the infusion tube 303 in a suitable position to prevent the infusion tube 303 from shaking or getting tangled during operation, ensuring that the cleaning fluid can be delivered smoothly and avoiding the infusion tube 303 from affecting the delivery of the cleaning fluid due to shaking or getting tangled, thus ensuring the normal progress of the cleaning work.
[0034] like Figure 2As shown, a protective cover 9 is bolted to one side of the base 1, and multiple heat dissipation holes 10 are provided through the outer wall of the protective cover 9. The protective cover 9 encloses the first servo motor 201 to prevent external dust, debris, etc. from entering the interior of the first servo motor 201 and affecting its normal operation. At the same time, the heat dissipation holes 10 can dissipate the heat generated by the first servo motor 201 in a timely manner, preventing the first servo motor 201 from being damaged due to overheating.
[0035] like Figure 5 As shown, the outer wall of the crossbar 209 is provided with two limiting rings 11, and a plastic soft ring 12 is provided on the opposite side of each limiting ring 11. When the discharge chamber 208 moves, the limiting rings 11 can limit the movement range of the discharge chamber 208 and prevent the discharge chamber 208 from exceeding the predetermined working area. The plastic soft ring 12 can reduce the friction between the discharge chamber 208 and the limiting rings 11, reduce wear, and at the same time play a certain buffering role to ensure the accuracy of the paste flux feeding.
[0036] Specifically, in use, the paste flux compaction and feeding device works as follows: The resistance wire 211 in the storage chamber 210 is energized to generate heat, which heats the paste flux in the storage chamber at a low temperature, maintaining its suitable fluidity. The paste flux is then conveyed through the conveying pipe 212 to the discharge chamber 208. The second servo motor 206 drives the lead screw 207 to rotate, causing the discharge chamber 208 to reciprocate horizontally. As the discharge chamber 208 moves, the paste flux flows evenly from the discharge chamber 208 between the drive roller 202 and the driven roller 203. Simultaneously, the first servo motor 201 drives the drive roller 202 to rotate, and through its cooperation with the driven roller 203, it compacts the spread paste flux, further distributing it evenly. Finally, the flux falls onto the conveyor belt 213 to complete the feeding process (e.g., ...). Figure 2 and Figure 3 (As shown); when the rolling of the paste flux stops, the booster pump 302 draws cleaning fluid from the storage box 301, delivers it to the outlet box 304 through the delivery pipe 303, and finally sprays it out from multiple nozzles 305 to clean the positions of the drive roller 202 and the driven roller 203. This thoroughly removes the residual paste flux from the surfaces of the drive roller 202 and the driven roller 203, improving cleaning efficiency and reducing manual operation (e.g., Figure 4 (As shown in the figure) This not only makes the paste flux easier to spread evenly and reduces the difficulty of the process, but also avoids the flux solidifying due to low temperature, which would affect the paste flux feeding process.
[0037] All technical features in this embodiment can be freely combined according to actual needs.
[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
