Description

Technical Field

[0001] This invention relates to the field of solder paste processing technology, specifically to a solder paste warming machine. Background Technology

[0002] In the surface mount technology (SMT) production process, solder paste usually needs to be refrigerated in a low-temperature environment to ensure its chemical activity. Before use, the solder paste must be taken out of the refrigerated environment and "warmed up" to restore its temperature to room temperature. Solder paste warming machine is mainly used to solve the problem of warming up solder paste after it is taken out of the low-temperature storage environment. For example, patent CN222778964U discloses a solder paste warming fixture, including a warming box. The upper end of the warming box has a cover with several equidistant through holes. A warming cylinder is installed at the lower end of each through hole, and the warming cylinder has several equidistant ventilation holes. An electric push rod is installed on the bottom wall of the warming cylinder, and a clamping assembly is installed at the top of the electric push rod. Several timers corresponding to the through holes are installed on the cover. A ventilation fan is installed on one side of the warming box. The clamping assembly secures the solder paste, and the electric push rod draws the solder paste into the warming cylinder, preventing insufficiently warmed solder paste from being removed. A pair of ventilation openings on the warming box, combined with the ventilation fan, allow airflow through the ventilation holes to pass over the solder paste, reducing the warming time and facilitating use. For example, patent CN119794500A discloses a solder paste reheating machine for electronic component production, comprising: a machine body, the top of which has evenly distributed placement slots, a cover plate for shielding the placement slots, a control console on one side of the machine body, and heat dissipation cavities on both sides of the machine body; by setting a drive component, the solder paste bottle can be rotated and heated during the reheating process inside the placement slot, improving the uniformity of heating, and at the same time, it can limit the protrusions during the heating process to avoid poor solder paste reheating effect due to insufficient heating time, and can reduce the water adhering to the surface of the solder paste bottle during refrigeration by collecting it uniformly, avoiding the situation where water vapor cannot be formed due to low heating temperature and is discharged during the opening process, resulting in water accumulation inside the placement slot affecting subsequent use.

[0003] However, based on the current solder paste warming equipment, it has been found that it still has certain drawbacks, such as: 1. The reheating and mixing processes are separated; traditional solder paste reheating devices usually only have the function of static reheating. After the solder paste is stored at low temperature, the flux and solder alloy powder inside are prone to sedimentation and separation. The existing processing method is often to first let the solder paste stand to reheat, and then transfer it to a mixer for mixing. This step-by-step operation not only increases the production process and time cost, but also easily causes solder paste contamination or oxidation during the transfer process.

[0004] 2. Condensation affects soldering quality; During the reheating process, due to the large temperature difference between the ambient temperature and the solder paste container, condensation is easily generated on the surface of the container. Existing reheating equipment lacks an effective dehumidification and water removal mechanism. If this moisture inadvertently seeps into the solder paste, it will directly lead to quality problems such as splattering during printing, solder balls or cold solder joints after soldering, which seriously affects the yield of electronic products.

[0005] 3. Uneven heating and poor adaptability: Existing reheating equipment often uses a single heating source, which can easily lead to uneven heating of solder paste. When dealing with small-batch, multi-batch production needs, traditional equipment is difficult to achieve independent temperature control management for different batches of solder paste, resulting in energy waste or poor reheating effect.

[0006] Therefore, we propose a solder paste warming machine to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a solder paste warming machine to solve the problems mentioned in the background art, such as the separation of the warming and mixing processes, which increases production process and time costs, the impact of condensation on soldering quality and the yield of electronic products, and the uneven heating and poor adaptability, which lead to energy waste or poor warming effect.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a solder paste warming machine, comprising a housing for direct placement on a table, a controller being provided at the bottom outer side of the housing, a driving element being fixedly installed at the bottom of the housing, and a top cover being connected to the top of the housing, characterized in that: the output end of the driving element is fixedly connected to a rotating shaft inserted into the housing, and a turntable and a top plate arranged parallel to each other inside the housing are fixedly connected to the top outer side of the rotating shaft; A ring plate is fixed in the middle of the inner wall of the outer shell, a platform is rotatably mounted on the inner side of the turntable, an outer gear ring is protruding from the outer side of the middle of the platform, an inner gear ring that meshes with the outer gear ring is fixed on the inner side wall of the ring plate, and clamping plates are symmetrically arranged on the upper surface edge of the platform. A heating mechanism is provided at the top center of the top plate, and the controller is electrically connected to the heating mechanism via a cable strip.

[0009] Furthermore: the turntable is rotatably connected to the inner side of the ring plate, and the platform is simultaneously rotatably installed inside the turntable and the top plate, with the platform set at equal angles on the inner sides of the turntable and the top plate.

[0010] Furthermore: the top surface of the platform is embedded with a carrier plate, the interior of the platform is filled with absorbent sponge, the interior of the carrier plate is uniformly provided with through holes, and the top of the absorbent sponge protrudes and is inserted into the through hole.

[0011] Furthermore, a water collection plate, also fixed inside the outer shell, is provided below the ring plate. The top of the water collection plate has a frustum-shaped structure, which is eccentrically positioned relative to the outer shell. A drain pipe connecting to the outside of the outer shell is provided on one side of the lowest point of the top surface of the water collection plate.

[0012] Furthermore: the heating mechanism is a first heating element, which is installed at the center of the top plate, and the first heating element and the connection node of the cable strip are electrically connected by a pin.

[0013] Furthermore: an eccentric frame is installed below the water collection plate and installed on the bottom of the inner side of the outer shell. An eccentric groove is opened inside the eccentric frame and deviates from the axis of the eccentric frame. A rotating wheel is rotatably installed in the middle of the eccentric frame and the rotating wheel is fixed to the outside of the rotating shaft. The outer side of the rotating wheel is provided with push plates at equal angles. Under the action of centrifugal force, the push plates slide inside the rotating wheel until they fit against the inner wall of the eccentric groove. The end of the push plate is provided with a sealing plate that keeps the eccentric groove sealed. One side of the eccentric frame is provided with an air inlet slot that communicates with the eccentric groove, and the outer side of the air inlet slot is connected to an air inlet hole located on the side wall of the outer shell. The other side of the eccentric frame is provided with an air outlet hole that communicates with the eccentric groove.

[0014] Furthermore: an exhaust pipe is connected to the outside of the air outlet, the top end of the exhaust pipe is inserted into the top of the air intake cover provided at the top of the top cover, and a jet nozzle located below the top cover is connected to the bottom side of the air intake cover.

[0015] Furthermore, a boss is provided on the top surface of the top cover at the lower interior of the air intake cover, and a gap is maintained between the boss and the air intake cover.

[0016] Furthermore: the heating element includes a central column installed at the center of the top surface of the top plate, and the side wall of the central column is provided with several slots. The heat insulation plate is inserted into the slots, dividing the space above the top plate into multiple independent heat recovery zones.

[0017] Furthermore, a fixing groove is also provided on the side wall of the central column, which is spaced apart from the slot. A second heating element is installed inside the fixing groove for independent heating of the reheating area.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects: the solder paste warming machine achieves automatic mixing while warming the solder paste through a combined revolution and rotation motion mechanism. At the same time, through the dual protection of physical flow guidance and forced air drying, it prevents condensate from seeping into the solder paste, ensuring soldering quality and product yield. It can realize the spatial division and independent temperature control of the warming chamber, adapting to the production needs of multiple batches and differences. 1. This solution includes a rotating shaft, a turntable, a top plate, and a platform. The rotating shaft, turntable, and top plate are driven to rotate by a driving element, which can drive the platform to revolve. At the same time, the platform rotates on its own axis while revolving through meshing with the ring plate. This allows the solder paste to be mixed evenly while the temperature is being restored, preventing the flux from separating from the solder. 2. This solution includes an absorbent sponge, with the solder paste container protected on the top of the carrier board. The bottom surface of the solder paste container is in contact with the top surface of the absorbent sponge, which can absorb dripping condensate. The condensate is then collected to one side by a water collection plate and discharged through a drain pipe. 3. This solution is equipped with an eccentric frame, a rotating wheel, an exhaust pipe, and an air inlet cover. The rotation of the rotating wheel inside the eccentric frame can compress the air through the push plate. The pressurized air is sprayed out through the exhaust pipe connected to the air inlet cover and the jet nozzle, which can accelerate the falling of condensate on the surface of the solder paste can and at the same time dry it, accelerating the removal and evaporation of moisture from the surface of the can. 4. This solution includes a central column, a heat insulation plate, and a second heating element. By disassembling the heat insulation plate and the central column, the space above the top plate can be divided, and the second heating element can be installed in the divided space to facilitate differentiated temperature control and reheating treatment within the same equipment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1 To address the issue that existing solder paste warming devices cannot simultaneously mix the solder paste during warming, requiring the warmed solder paste to be mixed again, thus increasing the number of steps involved; Please see Figures 1-6 The present invention provides the following technical solution: a solder paste warming machine, comprising: a shell 1, a controller 2, a drive element 3, a top cover 4, a rotating shaft 5, a turntable 6, a top plate 7, a ring plate 8, a platform 9, an inner gear ring 10, an outer gear ring 11, a platform 12, an absorbent sponge 13 and a clamping plate 14, as well as a first heating element 17 and a busbar 18. Wherein: the outer shell 1 is placed directly on the table for use, the outer bottom of the outer shell 1 is equipped with a controller 2, the bottom of the outer shell 1 is fixedly installed with a drive element 3, and the top of the outer shell 1 is connected with a top cover 4. The output end of the drive element 3 is fixedly connected with a rotating shaft 5 inserted into the outer shell 1, and the top outer side of the rotating shaft 5 is fixedly connected with a turntable 6 and a top plate 7 arranged parallel to each other inside the outer shell 1. A ring plate 8 is fixed in the middle of the inner wall of the outer shell 1. A platform 9 is rotatably mounted on the inner side of the turntable 6. The turntable 6 is rotatably connected to the inner side of the ring plate 8. The platform 9 is rotatably mounted inside the turntable 6 and the top plate 7. The platform 9 is set at equal angles on the inner sides of the turntable 6 and the top plate 7. An outer gear ring 11 is protruding from the outer side of the middle of the platform 9. An inner gear ring 10 that meshes with the outer gear ring 11 is fixed on the inner side wall of the ring plate 8. Clamping plates 14 are symmetrically arranged on the upper surface edge of the platform 9. A heating mechanism is provided at the top center of the top plate 7. The controller 2 is electrically connected to the heating mechanism through the busbar 18. The heating mechanism is a first heating element 17, which is installed at the center of the top plate 7. The connection node of the first heating element 17 and the busbar 18 is electrically connected through a pin.

[0023] In specific application scenarios, the outer shell 1 and the top cover 4 are connected by a snap fastener. When the top cover 4 is opened, the solder paste container can be placed directly on the top surface of the platform 9. Since the clamping plates 14 are symmetrically arranged on the outer side of the platform 9, the elasticity of the clamping plates 14 uses their inner edges to limit and clamp the solder paste container. The controller 2 controls the drive element 3 to start. Since the rotating shaft 5 of the output shaft of the drive element 3 is fixedly connected to the turntable 6 and the top plate 7, the drive element 3 drives the turntable 6 and the top plate 7 to rotate synchronously on the inner side of the ring plate 8. Since the platform 9 is installed on the inner side of the turntable 6 and the top plate 7, it drives the platform 9 to revolve around the axis of the rotating shaft 5. Meanwhile, an external gear ring 11 is integrally formed and protrudes from the outer side of the middle part of the platform 9. The platform 9 can mesh with the internal gear ring 10 protruding from the inner side wall of the ring plate 8 through the external gear ring 11. Thus, while the turntable 6 and the top plate 7 drive the platform 9 to rotate, the platform 9 is driven to rotate by the meshing of the external gear ring 11 and the internal gear ring 10. This allows the platform 9 to revolve and rotate simultaneously, so that the internal material is mixed evenly while reheating. At the same time, the controller 2 is electrically connected through the busbar 18. Its disconnection end can be connected to the power supply by means of pins, etc. Thus, the first heating element 17 in the middle of the top surface of the top plate 7 is powered and connected for control through the busbar 18 arranged on the bottom surface of the top cover 4, so that the heating device inside the first heating element 17 can work and carry out heating and reheating operations.

[0024] By adopting the above technical solution, the stage 9 is driven by the drive element 3 to revolve around the axis. At the same time, the stage 9 rotates synchronously during the revolution by meshing transmission, so as to drive the solder paste pot to achieve dynamic movement, so that the reheating and mixing are completed simultaneously, eliminating the risk of transfer contamination and time cost of traditional step-by-step operation. Moreover, the combined revolution and rotation motion generates shear force inside the solder paste, which effectively prevents the solder paste flux and solder alloy powder from separating.

[0025] Example 2 To address the issue that existing solder paste reheating equipment causes condensation on the surface of the solder paste container due to temperature differences during reheating, and that moisture mixing into the solder paste will directly affect the soldering quality; Please see Figures 1-10 The present invention also provides the following technical solution: a solder paste warming machine, which further includes: a water collection plate 15, a drain pipe 16, an eccentric frame 19, an eccentric groove 20, an air inlet groove 21, an air outlet 22, a rotating wheel 23, a push plate 24, a sealing plate 25, an air inlet 26, an exhaust pipe 27, an air inlet cover 28, a boss 29, and a jet nozzle 30; Among them: the top surface of the platform 9 is embedded with a carrier plate 12, the interior of the platform 9 is filled with a water-absorbing sponge 13, the interior of the carrier plate 12 is evenly provided with through holes, the top of the water-absorbing sponge 13 protrudes and is inserted into the through hole, the bottom of the ring plate 8 is provided with a water collection plate 15 that is also fixed inside the outer shell 1, the top of the water collection plate 15 is a frustum-shaped structure, the frustum-shaped structure is eccentrically positioned with respect to the outer shell 1, and a drain pipe 16 connected to the outside of the outer shell 1 is provided on one side of the lowest point of the top surface of the water collection plate 15. Below the water collection plate 15, an eccentric frame 19 is installed on the bottom of the inner side of the outer casing 1. An eccentric groove 20 is opened inside the eccentric frame 19, which is offset from the axis of the eccentric frame 19. A rotating wheel 23 is rotatably installed in the middle of the eccentric frame 19. The rotating wheel 23 is fixed to the outside of the rotating shaft 5. A push plate 24 is provided at equal angles on the outside of the rotating wheel 23. Under the action of centrifugal force, the push plate 24 slides inside the rotating wheel 23 until it fits against the inner wall of the eccentric groove 20. A sealing plate 25 is provided at the end of the push plate 24 to keep it sealed with the eccentric groove 20. An air inlet groove 21 is opened on one side of the eccentric frame 19, which communicates with the eccentric groove 20. An air inlet hole 26 located on the side wall of the outer casing 1 is connected to the outside of the air inlet groove 21. An air outlet hole 22 is opened on the other side of the eccentric frame 19, which communicates with the eccentric groove 20. An exhaust pipe 27 is connected to the outside of the air outlet 22. The top end of the exhaust pipe 27 is inserted into the top of the air inlet cover 28 provided at the top of the top cover 4. The bottom side of the air inlet cover 28 is connected to the jet head 30 located below the top cover 4. A boss 29 located on the top surface of the top cover 4 is provided inside the lower part of the air inlet cover 28. A gap is maintained between the boss 29 and the air inlet cover 28.

[0026] In specific application scenarios, when the solder paste can is placed on the surface of the carrier 9, its bottom surface is placed above the carrier plate 12 that is snapped onto the top surface of the carrier 9. The top of the water-absorbing sponge 13 filled inside the carrier 9 protrudes and snaps into the slots opened inside the carrier plate 12. When condensation occurs on the surface of the solder paste can, the water droplets will automatically slide down and drip under the action of gravity and the revolution and rotation of the solder paste can. The dripping water will be absorbed by the water-absorbing sponge 13. At the same time, since the bottom end of the water-absorbing sponge 13 is directly connected to the bottom of the turntable 6, the absorbed water will automatically drip downwards. The water collection plate 15 is fixed inside the outer shell 1 and is located below the turntable 6. The dripping water will fall directly onto the surface of the water collection plate 15. Since the top of the water collection plate 15 is a frustum structure and the center of the frustum structure does not coincide with the center of the outer shell 1, the water on its surface will concentrate on the lower side. The drain pipe 16 is directly connected to this side, thereby directly draining the condensation. Meanwhile, to improve the removal effect of condensate, an eccentric frame 19 is fixedly installed at the bottom of the inner part of the outer casing 1. The rotating wheel 23 is rotatably installed in the middle of the eccentric frame 19, and the rotating wheel 23 is fixed to the rotating shaft 5. When the rotating shaft 5 rotates and drives the platform 9 to move, it drives the rotating wheel 23 to rotate inside the eccentric frame 19. When the rotating wheel 23 rotates, the push plate 24, which is telescopically connected inside, slides outward under the action of centrifugal force, so that the top of the push plate 24 is attached to the inner wall of the eccentric groove 20 that is eccentrically set between the push plate 24 and the rotating wheel 23 through the sealing plate 25. The push plate 24 is made of self-lubricating and wear-resistant materials such as PTFE, POM, PEEK or impregnated graphite nylon to achieve long-term sealing. The inner end of the push plate 24 is elastically connected to the rotating wheel 23 through a spring to ensure that the push plate 24 extends outward stably and reduces the demand for centrifugal force. To ensure air pressurization even at low rotation speeds during solder paste reheating, one side of the rotating wheel 23 and one side of the eccentric groove 20 remain sealed and fitted together while the rotating wheel 23 rotates. When the rotating wheel 23 drives the push plate 24 to rotate, due to the eccentric setting of the rotating wheel 23 and the eccentric groove 20, the push plate 24 compresses the air that is detected intermittently between the rotating wheel 23 and the eccentric groove 20, causing the pressurized air to be discharged outward through the air outlet 22. Since the air outlet 22 is connected to the bottom end of the exhaust pipe 27, the air inlet cover 28 connected to the top end of the exhaust pipe 27 can spray the pressurized air from above onto the solder paste container through the air inlet cover 28. At the same time, an air inlet groove 21 is provided on the other side of the eccentric groove 20 opposite to the air outlet 22. The air inlet groove 21 is connected to the air inlet 26 for continuous air intake, thereby ensuring continuous air pressurization. Pressurized air enters through the top of the air inlet cover 28. Since the air inlet cover 28 is provided with a boss 29 fixed to the top surface of the outer shell 1, the protrusion of the boss 29 disperses the air to the detection through hole of the air inlet cover 28 for downward discharge. The interior of the through hole can be connected to the jet head 30. The air is evenly discharged through the air holes dispersed on the bottom surface of the jet head 30. The downward blowing of air can accelerate the efficiency of condensate dripping and achieve the purpose of dehumidification.

[0027] The above technical solution uses absorbent sponge 13 to adsorb condensate, and air compression is used to force the solder paste can to dry, which can eliminate condensate residue. At the same time, no additional air source is required, and the drying mechanism is fully integrated into the idle space at the bottom of the equipment shell 1. The eccentric frame 19 and the rotating wheel 23 are coaxially mounted on the rotating shaft 5, which does not occupy the effective working space of the reheat chamber. The air path is arranged along the side wall of the equipment, with a short path and no additional air duct loss, which meets the requirements of miniaturization and lightweight design. Moreover, the air blowing intensity is positively correlated with the mixing speed, which can adapt to the working conditions.

[0028] Example 3 Based on the above embodiments, this embodiment provides another implementation method for handling the reheating of different batches of solder paste. Please refer to [link to relevant documentation]. Figures 1-11 The present invention also provides the following technical solution: a solder paste warming machine, which further includes: a central column 31, a slot 32, a heat insulation plate 33, a fixing groove 34, and a second heating element 35; The heating element includes a central column 31 installed at the center of the top surface of the top plate 7. The side wall of the central column 31 is provided with several slots 32. The heat insulation plate 33 is inserted into the slots 32 to divide the space above the top plate 7 into multiple independent heat recovery zones. The side wall of the central column 31 is also provided with a fixing groove 34 spaced apart from the slots 32. The fixing groove 34 is fitted with a second heating element 35 for independent heating of the heat recovery zone.

[0029] In specific application scenarios, when different batches of solder paste need to be reheated for use, the first heating element 17 set in the center of the top plate 7 is replaced with a central pillar 31. The heat insulation plate 33 is inserted into the outside of the central pillar 31 through the slot 32, thereby dividing the internal space. The second heating element 35 is installed in the corresponding divided space through the fixing slot 34, and the second heating element 35 is used to heat and reheat the individual space.

[0030] By adopting the above technical solution, the separation of the heat insulation plate 33 can support the simultaneous warming and use of multiple batches of solder paste of different specifications, meet the needs of small-batch and diversified processing, and at the same time help reduce ineffective energy consumption and save energy.

[0031] Workflow: When using this solder paste warming machine, first open the top cover 4, place the refrigerated solder paste container on the platform 9, clamp it with the clamp 14, close the top cover 4, set the parameters through the controller 2 and start the equipment; The driving element 3 drives the stage 9 to perform a "revolution + rotation" compound motion, so as to achieve simultaneous reheating and mixing; The heating mechanism operates, or the zoned temperature control system heats as needed; The condensate is absorbed by the absorbent sponge 13 and discharged through the water collection plate 15, while the airflow is driven to dry the tank. After the work is completed, open the top cover 4 to remove the solder paste, and the equipment can be used for the next cycle of operation.
