Technical Field
[0001] This utility model relates to the technical field of pin tinning equipment, specifically a thermistor pin tinning equipment. Background Technology
[0002] Thermistor pin tinning equipment is a specialized automated device used to automatically tin the pins of thermistors. It is mainly used for pre-treatment of the pin surface before soldering in the electronic component manufacturing process. The purpose is to improve the solderability of the pins by uniformly coating them with a layer of solder, ensuring the reliability of subsequent soldering to the circuit board. However, in existing technologies, some traditional single-bath tinning processes suffer from problems such as solder dross accumulation, uneven wetting due to temperature stratification, and low efficiency in dross removal during downtime. Even in some simpler tinning equipment, to ensure the stability and positioning accuracy of the placement board, the placement board is secured with bolts. The mounting plate is fixed to the main body of the equipment using methods such as slots. When different sizes of pins need to be processed, the fixing device can be loosened and the mounting plate adapted to the corresponding pin size can be replaced. This design helps to ensure the accuracy of the pin position during the soldering process, improve the soldering quality and consistency. At the same time, the fixed mounting plate also facilitates the overall layout and debugging of the equipment, and reduces the impact of the mounting plate loosening or position change on the soldering effect. However, at present, most mounting plates are installed by bolts and screw holes, which makes it inconvenient to install or remove the mounting plate when soldering pins of different sizes.
[0003] A device for soldering the thermistor pins is proposed to address the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a device for soldering the pins of a thermistor, in order to solve the problem mentioned in the background art that the current installation of the placement board is mostly done by bolts and screw holes, which makes it inconvenient to install or disassemble the placement board.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermistor pin soldering device, including a workbench, wherein a connecting plate is fixedly installed on one side surface of the workbench near the top;
[0006] A drive motor is fixedly installed in the middle of the top surface of the connecting plate. A threaded rod is fixedly connected to the output end of the drive motor through one side surface of the connecting plate. A threaded plate is threadedly fitted on the surface of the threaded rod. Limiting rods are connected through the two sides of the threaded plate. A stabilizing plate is fixedly installed on both sides of the surface of the threaded plate. A first linear guide is fixedly installed inside the stabilizing plate. A sliding sleeve is connected through the surface of the first linear guide. A fixing block is fixedly connected to the side surface of the sliding sleeve near the bottom.
[0007] Also includes:
[0008] A locking rod is connected through the middle of the interior of the fixing block;
[0009] The surface of the lever is fitted with a tension spring;
[0010] Among them, a blocking block is fixedly connected to the side surface of the lever away from the fixing block.
[0011] Preferably, one side surface of the tension spring is fixedly connected to the fixing block, and the other side surface of the tension spring is fixedly connected to the blocking block.
[0012] Preferably, a fixing plate is rotatably connected to the bottom surface of the threaded rod, the fixing plate is fixedly connected to the worktable, the fixing plate is fixedly connected to the limiting rod, and extension blocks are symmetrically installed on both sides of the fixing plate.
[0013] Preferably, a hot solder bath is fixedly installed on the surface of the workbench, and a collection frame is fixedly installed on one side of the hot solder bath.
[0014] Preferably, a second linear guide rail is fixedly installed on one side surface of the extension block, and a scraper is connected through the surface of the second linear guide rail.
[0015] Preferably, a sliding groove is formed in the middle of the surface of the fixed block, a sliding block is slidably connected inside the sliding groove, a slot is formed on one side inside the sliding block, and a placement plate is fixedly connected to the top surface of the sliding block.
[0016] Preferably, the locking rod engages with the locking slot.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This thermistor pin soldering device, through the cooperation of a fixing block, a sliding groove, a sliding block, a slot, a placement plate, a locking rod, a tension spring, and a blocking block, allows for relatively convenient replacement of the placement plate. The specific details are as follows:
[0018] 1. By setting up a fixed block, sliding groove, sliding block, slot, placement plate, locking rod, tension spring, and blocking block, when soldering is required for a different pin type after soldering one type, the placement plate needs to be replaced. During replacement, pulling the blocking block moves the locking rod, which in turn moves the tension spring, causing it to deform. After the locking rod separates from the slot, pushing the placement plate causes the sliding block on the placement plate to slide inside the sliding groove, misaligning the locking rod and slot, allowing the placement plate to be removed for further processing. When replacing different placement boards, the sliding block is aligned with the sliding groove. The placement board is then pushed, causing the sliding block on the placement board to slide inside the sliding groove. After the sliding block slides to a certain position inside the sliding groove, the locking rod and the locking groove are aligned at the same level. Then, the tension spring causes the blocking block and the locking rod to return to their original positions, allowing the locking rod and the locking groove to re-engage, thus completing the installation of the placement board. This makes it easier to replace the placement board. At the same time, fixing the placement board facilitates the overall layout and debugging of the equipment and reduces the impact of loose or changed placement board position on the soldering effect.
[0019] 2. By setting up an extension block, a second linear guide rail, and a scraper, when soldering the pins, the placement plate is moved above the solder bath through the cooperation of the drive motor, threaded rod, threaded plate, limit rod, stabilizing plate, first linear guide rail, sliding sleeve, fixing block, and fixing plate. Then, by controlling the switch, the second linear guide rail is activated, causing it to move its own sliding sleeve. This movement of the sliding sleeve moves the scraper, allowing it to scrape the surface of the solder bath. Finally, by activating the drive motor, the output end of the drive motor drives the threaded rod... The rotation of the rod, through the rotation of the threaded rod, causes the threaded plate to descend. Simultaneously, the two sides of the threaded plate are slidably connected to the limiting rod, while the bottom of the limiting rod is fixedly connected to the fixed plate and the top is fixedly connected to the connecting plate. Through the cooperation between the limiting rod, the fixed plate, and the connecting plate, the threaded plate can be limited, allowing it to move on the threaded rod. As the threaded plate descends, it causes the stabilizing plate and the fixing block to descend as well. After the stabilizing plate and the fixing block descend to a certain extent, the pins on the placement plate come into contact with the solder bath, thus completing the soldering process on the pins.

[0027] 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.
[0028] Please see Figure 1-6 This utility model provides a technical solution: a thermistor pin soldering device, including a workbench 1, a connecting plate 2 fixedly installed on one side surface of the workbench 1 near the top; a drive motor 3 fixedly installed in the middle of the top surface of the connecting plate 2, a threaded rod 4 fixedly connected to the output end of the drive motor 3 through one side surface of the connecting plate 2, a threaded plate 5 threadedly fitted on the surface of the threaded rod 4, limit rods 6 penetrating through both sides of the threaded plate 5, a stabilizing plate 7 fixedly installed on both sides of the surface of the threaded plate 5, a first linear guide rail 8 fixedly installed inside the stabilizing plate 7, a sliding sleeve 9 penetrating through the surface of the first linear guide rail 8, and a fixing block 10 fixedly connected to one side surface of the sliding sleeve 9 near the bottom; it also includes: a clamping rod 21 penetrating through the middle of the inside of the fixing block 10; wherein, a tension spring 22 is fitted on the surface of the clamping rod 21; wherein, a blocking block 23 is fixedly connected to the side surface of the clamping rod 21 away from the fixing block 10, such as Figure 1-6As shown, by setting up the cooperation between the fixing block 10, sliding groove 17, sliding block 18, card slot 19, placement plate 20, card rod 21, tension spring 22 and blocking block 23, the placement plate 20 can be replaced relatively easily.
[0029] One surface of the tension spring 22 is fixedly connected to the fixing block 10, and the other surface of the tension spring 22 is fixedly connected to the blocking block 23, as shown below. Figure 6 As shown, when soldering is required for one type of pin after soldering is completed, and another type of pin needs to be soldered, the placement board 20 needs to be replaced. When replacing the placement board 20, the blocking block 23 is pulled. After the blocking block 23 is pulled, the locking rod 21 can be moved. At the same time, the movement of the blocking block 23 will cause the tension spring 22 to move, thereby causing the tension spring 22 to deform. After the locking rod 21 separates from the slot 19, the placement board 20 is pushed, causing the sliding block 18 on the placement board 20 to slide inside the sliding groove 17. This causes the locking rod 21 to be misaligned with the slot 19, thereby allowing the placement board 20 to be disassembled and replaced.
[0030] A fixed plate 11 is rotatably connected to the bottom surface of the threaded rod 4. The fixed plate 11 is fixedly connected to the worktable 1 and to the limiting rod 6. Extension blocks 12 are symmetrically installed on both sides of the fixed plate 11. A solder bath 13 is fixedly installed on the surface of the worktable 1. A collection frame 14 is fixedly installed on one side of the solder bath 13. A second linear guide 15 is fixedly installed on one side of the extension block 12. A scraper 16 is connected through the surface of the second linear guide 15. Figure 1As shown, by setting the extension block 12, the second linear guide rail 15, and the scraper 16, when the pins are hot-tinned, the cooperation between the drive motor 3, the threaded rod 4, the threaded plate 5, the limit rod 6, the stabilizing plate 7, the first linear guide rail 8, the sliding sleeve 9, the fixing block 10, and the fixing plate 11 moves the placement plate 20 above the hot-tinning bath 13. At this time, the control switch is activated to start the second linear guide rail 15, causing the second linear guide rail 15 to move its own sliding sleeve. The movement of the sliding sleeve drives the scraper 16 to move, so that the scraper 16 can scrape the surface of the hot-tinning bath 13. Then, by starting the drive motor 3, the output end of the drive motor 3 drives... The rotation of the threaded rod 4 causes the threaded plate 5 to descend. Simultaneously, the two sides of the threaded plate 5 are slidably connected to the limiting rod 6. The bottom of the limiting rod 6 is fixedly connected to the fixing plate 11, and the top is fixedly connected to the connecting plate 2. Through the cooperation between the limiting rod 6, the fixing plate 11, and the connecting plate 2, the threaded plate 5 is limited, allowing it to move on the threaded rod 4. As the threaded plate 5 descends, it causes the stabilizing plate 7 and the fixing block 10 to descend as well. Once the stabilizing plate 7 and the fixing block 10 have descended to a certain extent, the pins on the placement plate 20 come into contact with the solder bath 13, thus completing the soldering process on the pins.
[0031] A sliding groove 17 is formed in the middle of the surface of the fixed block 10. A sliding block 18 is slidably connected inside the sliding groove 17. A slot 19 is formed on one side of the inside of the sliding block 18. A placement plate 20 is fixedly connected to the top surface of the sliding block 18. The locking rod 21 is engaged with the slot 19. Figure 4-6 As shown, when installing different placement plates 20, after aligning the sliding block 18 with the sliding groove 17, the placement plate 20 is pushed so that the sliding block 18 on the placement plate 20 slides inside the sliding groove 17. After the sliding block 18 slides to a certain position inside the sliding groove 17, the locking rod 21 and the locking slot 19 are on the same horizontal line. Then, through the action of the tension spring 22, the blocking block 23 and the locking rod 21 can be driven to return to their original positions, so that the locking rod 21 and the locking slot 19 are re-engaged, thereby completing the installation of the placement plate 20. This makes it easier to replace the placement plate 20. At the same time, the fixing of the placement plate 20 facilitates the overall layout and debugging of the equipment and reduces the impact of loosening or changing position of the placement plate 20 on the soldering effect.
[0032] Working principle: Before using this thermistor pin soldering device, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 6As shown, by first setting up a fixed block 10, a sliding groove 17, a sliding block 18, a slot 19, a placement plate 20, a locking rod 21, a tension spring 22, and a blocking block 23, when tinning is needed for a different pin type after tinning one type of pin, the placement plate 20 needs to be replaced. When replacing the placement plate 20, the blocking block 23 is pulled. After the blocking block 23 is pulled, the locking rod 21 can be moved. At the same time, the movement of the blocking block 23 will cause the tension spring 22 to move, thus deforming the tension spring 22. After the locking rod 21 separates from the slot 19, the placement plate 20 is pushed, causing the sliding block 18 on the placement plate 20 to slide inside the sliding groove 17. This causes the locking rod 21 to be misaligned with the slot 19, thus allowing the placement plate to be tinned. The placement plate 20 is disassembled for replacement. When installing different placement plates 20, after aligning the sliding block 18 with the sliding groove 17, the placement plate 20 is pushed so that the sliding block 18 on the placement plate 20 slides inside the sliding groove 17. After the sliding block 18 slides to a certain position inside the sliding groove 17, the locking rod 21 and the locking slot 19 are on the same horizontal line. Then, through the action of the tension spring 22, the blocking block 23 and the locking rod 21 can be driven to return to their original positions, so that the locking rod 21 and the locking slot 19 are re-engaged, thus completing the installation of the placement plate 20. This makes it easier to replace the placement plate 20. At the same time, the fixing of the placement plate 20 facilitates the overall layout and debugging of the equipment and reduces the impact of loosening or changing position of the placement plate 20 on the soldering effect.
[0033] Secondly, by setting up the extension block 12, the second linear guide rail 15, and the scraper 16, when the pins are hot-tinned, the cooperation between the drive motor 3, the threaded rod 4, the threaded plate 5, the limit rod 6, the stabilizing plate 7, the first linear guide rail 8, the sliding sleeve 9, the fixing block 10, and the fixing plate 11 moves the placement plate 20 above the hot-tin bath 13. At this time, the control switch is activated to start the second linear guide rail 15, causing the second linear guide rail 15 to move its own sliding sleeve. The movement of the sliding sleeve drives the scraper 16 to move, allowing the scraper 16 to scrape the surface of the hot-tin bath 13. Then, by starting the drive motor 3, the output end of the drive motor 3 is driven... The rotation of the threaded rod 4 causes the threaded plate 5 to descend. Simultaneously, the two sides of the threaded plate 5 are slidably connected to the limiting rod 6. The bottom of the limiting rod 6 is fixedly connected to the fixing plate 11, and the top is fixedly connected to the connecting plate 2. Through the cooperation between the limiting rod 6, the fixing plate 11, and the connecting plate 2, the threaded plate 5 is limited, allowing it to move on the threaded rod 4. As the threaded plate 5 descends, it causes the stabilizing plate 7 and the fixing block 10 to descend as well. Once the stabilizing plate 7 and the fixing block 10 have descended to a certain extent, the pins on the placement plate 20 come into contact with the solder bath 13, thus completing the soldering process on the pins.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
