Description

Technical Field

[0001] This invention relates to the technical field of auxiliary equipment for tin melting furnaces, and in particular to a tin level monitoring and replenishment device for tin melting furnaces. Background Technology

[0002] A solder level monitoring and replenishment device for solder furnaces is an automated device installed on solder furnaces to monitor the solder level in real time and automatically replenish solder bars. Its core functions are to stabilize the solder level, ensure soldering quality, reduce manual intervention, and improve production efficiency. It mainly consists of a level detection module, a control module, a solder bar storage and feeding mechanism, a solder melting auxiliary structure, and a frame fixing assembly. Common solder level monitoring and replenishment devices for solder furnaces often use a direct cylinder push method, causing solder blocks to fall directly into the solder, which can easily lead to solder splashing. Furthermore, when the solder reaches the preset height, it cannot be stopped in time, requiring the addition of whole blocks, resulting in exceeding the preset amount. In addition, its sensors are often in direct contact with the solder, making them highly susceptible to fluctuations in the solder level. Whether it's solder dross, oxides on the solder surface, or surface agitation caused by adding solder blocks, all can easily lead to sensing errors.

[0003] To address the aforementioned issues, a search revealed a patent with publication number CN218836398U that discloses an automatic solder pot with adjustable solder levels. The patent proposes that "by designing a solder-adding component, information about the molten solder inside the mother furnace is transmitted to the solder-adding component under the action of upper and lower limit liquid level sensors, controlling the position of the solder-adding frame. By adding a large amount of solder blocks into the solder-adding frame and submerging it inside the mother furnace, the frequency of manual solder addition can be reduced, while also reducing burns caused by hot molten solder splashing from direct manual solder addition. The design of the mother furnace and the daughter furnace allows the molten solder inside the mother furnace to flow into the daughter furnace through an overflow hole, reducing the need for additional solder." The liquid level fluctuations caused by the liquid improve quality. The position of the limit rod can be adjusted by adjusting the component, which can reduce the requirements of the solder strip on the liquid level. Although the setting of buffer guide component, quantitative solder feeding structure and non-contact liquid level sensor effectively avoids the splashing of solder caused by direct drop of solder block, realizes segmented and precise solder replenishment, avoids the problem of excessive solder replenishment, and isolates the interference of solder and solder dross on the sensing component, improving the stability of liquid level monitoring, the overall device structure is complicated, the manufacturing and maintenance costs are higher, the high temperature furnace environment can accelerate the aging of components, and the sensing element is still affected by the flue gas in the furnace, resulting in a small detection error.

[0004] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0005] The purpose of this invention is to provide a molten tin level monitoring and replenishment device for molten tin furnaces, in order to solve the problems mentioned in the background art. In the process of use, the existing molten tin level monitoring and replenishment devices for molten tin furnaces mostly adopt the direct push method of cylinder to replenish tin. The tin block falls directly into the molten tin, which easily causes molten tin to splash. When the molten tin reaches the preset height, the material cannot be stopped in time, and the tin block can only be added in whole blocks, resulting in the replenishment amount exceeding the standard. At the same time, the sensor is in direct contact with the molten tin, and is easily affected by tin dross, oxides on the surface of the molten tin, and liquid level fluctuations caused by the addition of tin blocks, which leads to the problem of sensor failure and misjudgment.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This molten solder furnace molten solder level monitoring and replenishment device, through the setting of a conveying mechanism and a moving mechanism, allows for the orderly conveying of solder blocks during use. The conveying mechanism enables the controllable conveying of solder blocks. The limiting rod provides guidance for the second push plate, the first spring provides spring force, and the shaft and sleeve provide rolling friction to reduce friction and prevent solder blocks from getting stuck. When the solder blocks move to the cylinder output end under the action of the spring force, the cylinder can orderly convey the solder blocks to the inclined plate. Under the dual friction of the anti-slip belt and the conveyor belt, the solder blocks are stuck on the inclined plate. Then, the drive motor can realize the slow and controllable conveying of solder blocks, which can prevent the solder blocks from being directly fed into the molten solder, causing the molten solder to splash, and can also be added and stopped immediately. 2. This solder level monitoring and replenishment device for a solder furnace, through the setting of a clamping mechanism and a sensing mechanism, allows the replenishment device to be connected to the solder furnace during use, improving the stability and adaptability of the replenishment device. The float of the sensing mechanism completely isolates the sensor from the high-temperature solder, solder dross, and oxide layer, preventing the sensor from being contaminated, stuck, or damaged by high temperature, greatly extending its service life. With the help of the guide column, it achieves pure vertical guiding movement. With the help of the second spring buffering the buffer surface fluctuation, it can effectively filter the interference of liquid surface oscillation during soldering, avoid false triggering and false action, significantly improve detection stability and control accuracy, and ensure long-term stability of the liquid level.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 The present invention provides a technical solution: a molten tin furnace molten tin level monitoring and replenishment device, comprising a base 1, a conveying mechanism 4, and a sensing mechanism 8.

[0021] Furthermore, a connecting plate 404 is connected to the upper surface of the side plate 402, and a first bracket 405 is connected to one side surface of the connecting plate 404. The inner ring surface of the mounting groove of the first bracket 405 is connected to the outer ring surface of the motor 406. Through the setting of the connecting plate 404 and the first bracket 405, the motor 406 can be stably supported and fixed during use. The connecting plate 404 fixes the first bracket 405 on the side plate 402, providing a stable mounting platform for the motor 406, ensuring that the motor 406 will not deviate or shake during operation, and ensuring stable power output of the conveying mechanism 4. The mounting groove of the first bracket 405 is precisely matched with the outer ring of the motor 406, which can effectively disperse the vibration generated by the motor 406 during operation and prevent the vibration from being transmitted to the conveyor belt 408 and affecting the accuracy of solder block conveying.

[0022] Furthermore, a second connecting rod 409 is connected to the inner surface of the conveyor belt 408, and a connecting block 410 is fitted onto the outer surface of one end of the second connecting rod 409. One side surface of the connecting block 410 is connected to one side surface of the inclined plate 403, and an anti-slip strip 411 is connected to the upper surface of the inclined plate 403. Through the arrangement of the second connecting rod 409, the connecting block 410, and the anti-slip strip 411, stable transmission of the conveyor belt 408 and anti-slip conveying of the solder block can be achieved during use. The second connecting rod 409 cooperates with the connecting block 410. 10. Provides driven support for conveyor belt 408 to ensure the cyclic operation of conveyor belt 408. Anti-slip belt 411 increases the friction between inclined plate 403 and solder block to prevent solder block from sliding during the conveying process, ensuring that solder block can be conveyed smoothly and controllably, and preventing solder block from falling directly and causing solder molten metal to splash. Second connecting rod 409 fits tightly against the inner wall of conveyor belt 408. Connecting block 410 is fixed at the end of inclined plate 403. Anti-slip belt 411 is made of high temperature and wear resistant material, which is suitable for the high temperature environment around the solder pot and is not easy to wear after long-term use.

[0023] Furthermore, a moving mechanism 5 is provided on one side of the outer compartment 401. The moving mechanism 5 includes a support platform 501. A second bracket 502 is connected to the upper surface of the support platform 501. A cylinder 503 is installed on the upper surface of the second bracket 502. The output end of the cylinder 503 is connected to a first push plate 504. Through the arrangement of the support platform 501, the second bracket 502, the cylinder 503, and the first push plate 504, the orderly pushing of solder blocks can be achieved during use. The support platform 501 and the second bracket 502 provide a stable mounting base for the cylinder 503. The cylinder 503 drives the first push plate 504 to reciprocate, pushing the solder blocks in the outer compartment 401 one by one onto the inclined plate 403, realizing the quantitative and orderly delivery of solder blocks, avoiding excessive solder replenishment caused by adding too many solder blocks at once. The support platform 501 is fixedly connected to the outer compartment 401, improving the overall stability.

[0024] Furthermore, a shaft 505 is connected to the inner wall side of the outer chamber 401, and a sleeve 506 is fitted on the outer ring surface of the shaft 505. Through the setting of the shaft 505 and the sleeve 506, the friction force when the solder block moves in the outer chamber 401 can be reduced during use. The shaft 505 provides installation support for the sleeve 506, and the sleeve 506 can rotate with the movement of the solder block, converting the sliding friction between the solder block and the inner wall of the outer chamber 401 into rolling friction, effectively preventing the solder block from getting stuck and ensuring smooth solder block conveying. The shaft 505 is made of corrosion-resistant material, which can resist the wear caused by the friction of the solder block. The sleeve 506 has a smooth surface and is resistant to high temperature, adapting to the environment inside the outer chamber 401. Multiple sets of shafts 505 and sleeves 506 are evenly distributed inside the outer chamber 401 to ensure that the solder block is subjected to uniform force during movement, further avoiding the problem of getting stuck.

[0025] Furthermore, a limiting rod 507 is connected to the inner surface of the transverse through hole of the outer chamber 401. A second push plate 508 is connected to one side surface of the limiting rod 507, and a first spring 509 is sleeved on the outer ring of the limiting rod 507. One side surface of the first spring 509 is connected to one side surface of the second push plate 508, and the other side surface of the first spring 509 is connected to the inner wall side of the outer chamber 401. Through the setting of the limiting rod 507, the second push plate 508, and the first spring 509, the elastic pre-tightening and orderly arrangement of the solder blocks can be achieved during use. The limiting rod 507 is the second push plate. 508 provides guiding support, and the first spring 509 provides elastic force to the second push plate 508, pushing the second push plate 508 to pre-tighten the solder block in the outer chamber 401 towards the pushing direction of the cylinder 503, so that the solder block is always in the ready-to-push state, ensuring that the cylinder 503 can accurately push a single solder block each time, improving the solder replenishment accuracy. The limit rod 507 is clearance-fitted with the through hole of the outer chamber 401 to ensure smooth movement of the second push plate 508. The first spring 509 has good elastic restoring ability and can automatically adjust the pre-tightening force according to the number of solder blocks, avoiding damage to the solder block due to excessive pre-tightening force or loosening of the solder block due to insufficient pre-tightening force.

[0026] Furthermore, a clamping mechanism 6 is provided above the support plate 2. The clamping mechanism 6 includes a crossbar 601. Through the setting of the crossbar 601, it can provide an installation carrier for other components of the clamping mechanism 6 during use. The crossbar 601 serves as the installation axis of the first clamping plate 602 and the second clamping plate 603, providing support for the clamping and fixing action, ensuring that the clamping mechanism 6 can stably adapt and install the device with the tin furnace 7. The crossbar 601 is made of high-strength metal material, which can withstand the squeezing force generated during clamping and is not easily deformed. Its surface is smoothed to facilitate the sliding of the second clamping plate 603 along its axis. The lower surface of the crossbar 601 is fixedly connected to the support plate 2 to ensure a firm installation and provide a stable structural foundation for subsequent clamping actions.

[0027] Furthermore, a first clamping plate 602 is fitted onto the outer ring surface of one end of the crossbar 601, and a second clamping plate 603 is fitted onto the outer ring surface of the crossbar 601. A fixing block 604 is connected to the upper surface of the support plate 2, and a screw 605 is threaded onto the inner ring surface of the fixing block 604. One side surface of the screw 605 is fixedly connected to one side surface of the second clamping plate 603. Through the arrangement of the first clamping plate 602, the second clamping plate 603, the fixing block 604, and the screw 605, adjustable clamping and fixing of the device to the tin furnace 7 can be achieved during use. 4 provides threaded support for the screw 605. When the screw 605 is rotated, it can drive the second clamping plate 603 to move along the crossbar 601 towards the first clamping plate 602, thereby clamping and fixing the device on the edge of the tin furnace 7 of different specifications, improving the adaptability and installation stability of the device. The inner sides of the first clamping plate 602 and the second clamping plate 603 are provided with anti-slip pads, which can increase the friction with the edge of the tin furnace 7 and prevent the device from sliding. The end of the screw 605 is provided with a knob for easy manual rotation and adjustment. The fixing block 604 is welded and fixed to the support plate 2, and the connection is firm and can withstand the reaction force during clamping.

[0028] Furthermore, a vertical rod 801 is connected to the bottom surface of the inner ring of the tin furnace 7. One side surface of the vertical rod 801 is connected to one side surface of the guide post 802. Through the setting of the vertical rod 801 and the guide post 802, vertical guidance can be provided for the sensing mechanism 8 during use. The vertical rod 801 fixes the guide post 802 inside the tin furnace 7, providing vertical guidance for the movement of the sleeve block 803 and the float 804, ensuring that the float 804 can only move vertically along the rise and fall of the molten tin surface, avoiding the float 804 from shifting or shaking, and improving the accuracy of liquid level monitoring. The vertical rod 801 is made of high temperature and corrosion resistant material, and can be used for a long time in the high temperature environment inside the tin furnace 7. The surface of the guide post 802 is smooth and has a clearance fit with the sleeve block 803, reducing the friction when the sleeve block 803 moves.

[0029] Furthermore, the inner bottom surface of the float 804 is connected to a limiting post 805, and the outer ring of the limiting post 805 is fitted with a second spring 806. The inner wall side of the solder pot 7 is connected to a sensor 807, which is located directly below the upper contact of the second spring 806. Through the setting of the limiting post 805, the second spring 806, and the sensor 807, non-contact monitoring and fluctuation buffering of the solder liquid level can be realized during use. When the float 804 rises and falls with the solder liquid level, the limiting post 805 moves synchronously with the float 804. The second spring 806 can buffer the oscillation and fluctuation of the liquid level during soldering and prevent the sensor 807 from being triggered falsely. When the solder liquid is replenished to a predetermined threshold, the upper contact of the second spring 806 contacts the sensor 807, which can stop the soldering.

[0030] Working principle: First, place the base 1 on the working surface, then place the support plate 2 on the base 1. Next, fix the device to the edge of the solder pot 7 through the clamping mechanism 6. Specifically, place the first clamping plate 602 against one side of the solder pot 7, rotate the screw 605 to make it rotate within the fixing block 604, and drive the second clamping plate 603 to move along the crossbar 601 towards the first clamping plate 602 until the device is firmly clamped to the edge of the solder pot 7. Then, put the solder block to be replenished into the outer chamber 401 of the conveying mechanism 4. The shaft 505 and sleeve 506 in the outer chamber 401 can reduce the movement of the solder block. The friction force prevents the solder blocks from getting stuck, while the first spring 509 on the limit rod 507 pushes the second push plate 508 to pre-tighten the solder blocks towards the moving mechanism 5. Then, the cylinder 503 is activated. Supported by the support platform 501 and the second bracket 502, the cylinder 503 drives the first push plate 504 to reciprocate, pushing the solder blocks in the outer compartment 401 one by one onto the inclined plate 403 of the conveying mechanism 4. The anti-slip strip 411 on the inclined plate 403 prevents the solder blocks from slipping. Then, the motor 406 is activated. Supported by the connecting plate 404 and the first bracket 405, the motor 406 drives the... The first connecting rod 407 rotates, driving the conveyor belt 408 to operate. The conveyor belt 408, with the auxiliary support of the second connecting rod 409 and the connecting block 410, achieves cyclic transmission, slowly and controllably conveying the solder block towards the solder pot 7, preventing the solder block from falling directly and causing molten solder to splash. Simultaneously, it achieves precise solder replenishment with immediate addition and stop. During the solder replenishment process, the sensing mechanism 8 inside the solder pot 7 monitors the molten solder level in real time. The vertical rod 801 fixes the guide column 802 inside the solder pot 7. As the float 804 rises and falls with the molten solder level, the sleeve block 803 moves vertically along the guide column 802. The second spring 806 can buffer the oscillation of the liquid surface during the soldering process and prevent the sensor 807 from being triggered falsely. When the solder liquid is replenished to the predetermined level, the contact point at the upper end of the second spring 806 contacts the sensor 807. The sensor 807 sends a signal to stop the cylinder 503 and the motor 406, thus stopping the soldering. The support column 3 and the support plate 2 provide stable support for the conveying mechanism 4 and the moving mechanism 5, ensuring that the entire device operates stably during the soldering process. Ultimately, it achieves orderly, controllable, splash-proof, and high-precision automatic soldering operation for the soldering furnace 7. The cylinder 503 is model SMC CDJ2B16-60Z, the motor 406 is model Shinano SST43D2120, and the sensor 807 is model Omron E2EH-X12D1.
