Description

Technical Field

[0001] The utility model relates to the technical field of motor production equipment, in particular to automatic tin dipping equipment. Background Art

[0002] In the manufacturing process of electronic components, tinning is a common and necessary process to improve the conductivity of wire pins and prevent oxidation. By immersing the wire pins in molten tin, a uniform and stable tin layer is formed, thereby improving their conductivity and soldering performance. However, traditional tinning equipment has many practical problems, resulting in unsatisfactory tinning results.

[0003] First, the structure of conventional immersion tin equipment is often complex, and the operation process requires more manpower and time, which increases production costs.

[0004] In addition, many existing devices lack effective structures for scraping off the oxide film. The presence of the oxide film will seriously affect the adhesion ability of tin, resulting in poor final tin immersion effect.

[0005] Secondly, existing immersion tinning equipment also has shortcomings in its automatic tin addition function. Many devices cannot achieve automatic tin addition, making it difficult to maintain the temperature and composition of the tin solution at the optimal state, further affecting the quality and efficiency of immersion tinning.

[0006] Furthermore, adjusting the tin immersion depth is also an issue that cannot be ignored. Traditional equipment often lacks a flexible structure for adjusting the tin immersion depth, which not only limits the application range of the equipment, but may also cause uneven tin layer, affecting the reliability of subsequent soldering.

[0007] Finally, existing immersion tin equipment lacks automated testing capabilities, making quality control during production difficult. Existing equipment often relies on manual inspection, which not only increases labor costs but also easily leads to missed inspections or misjudgments, compromising product consistency and reliability.

[0008] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0032] The automatic tin dipping equipment of the utility model integrates the functions of automatic loading, automatic tin dipping, automatic testing and automatic unloading, and meets the requirements of the modern electronic manufacturing industry for high efficiency, high quality and automation.

[0033] More specifically, the loading device 4 preferably includes a material rack for temporarily storing a plurality of coils, a first cylinder for driving the material rack to rise and fall, and a second cylinder for driving the material rack to move inward and outward (equivalent to the radial direction of the turntable 2).

[0034] Furthermore, the fixture 3 includes a base 31 fixed on the turntable 2, and a slider 32 that can be raised and lowered is slidably connected to the base 31. The slider 32 is provided with a plurality of clamping heads 33 that can clamp the coil.

An elastic reset member 34 that can pull the slider 32 upward is provided between the slider 32 and the base 31. The elastic reset member 34 is preferably a spring to ensure that the slider can quickly return to its initial position after the tinning is completed, thereby optimizing the production cycle.

[0035] The tinning device 5 is the core of this equipment. It performs a series of automated operations, including automatic scraping of oxide films, automatic tin addition, and automatic tin dipping, thereby ensuring high quality and efficiency during the tinning process. Specifically, the tinning device 5 comprises a tinning frame 51, on which is mounted a tin furnace 52 with a built-in heating device. A pressure assembly 53 and a tin addition assembly 54 are located above the tin furnace 52, and a tin scraping assembly 55 is located on one side of the tin furnace 52. This is described in detail below.

[0036] First, the pressing assembly 53 includes a pressing block 531 slidably connected to the tinning frame 51. The pressing block 531 is raised and lowered by a lifting drive 532, preferably a motor and ball screw drive assembly. The pressing block 531 includes a downwardly extending pressing portion 533, the lower end of which is provided with a pressing surface 5331. This surface is used to press the slider 32 downward into the tinning pot 52 during the tinning process, ensuring that the coil pins are fully immersed in the tin solution.

[0037] Furthermore, a downwardly extending limit rod 534 is provided on the top pressure block 531. The lower end of the limit rod 534 can extend into the bottom of the tin furnace 52 and is designed to limit the depth of descent of the top pressure block 531, thereby controlling the depth of tin immersion. In order to be able to flexibly adjust the downward extension length of the limit rod 534, a height adjustment structure is provided between the top pressure block 531 and the limit rod 534. The height adjustment structure includes a through hole 5311 provided on the top pressure block 531, through which the limit rod 534 passes, and a top screw 5312 for locking the limit rod 534 and the side wall of the through hole 5311 is provided. The provision of the limit rod 534 allows the operator to flexibly adjust according to the height of different coils, further improving the adaptability of tin immersion.

[0038] In order to ensure that the liquid level of the tin liquid in the tin furnace 52 is always in an appropriate state, a liquid level detection component 521 is provided in the tin furnace 52. The liquid level detection component 521 can monitor the liquid level of the tin liquid in real time to ensure the safety and quality of the production process.

[0039] Regarding tin addition, the tin addition assembly 54 includes a tin breaker 541 and a tin wire guide tube 542, the lower end of which extends directly above the tin pot 52. This design ensures that the tin wire enters the tin pot 52 accurately, facilitating subsequent tin addition operations. Both the tin addition assembly 54 and the liquid level detection assembly 521 are electrically connected to the control system, allowing the tin addition assembly 54 to automatically add or stop tin based on the liquid level, thus avoiding situations where the tin liquid is too much or too little, ensuring normal operation of the equipment.

[0040] To address the issue of tin scraping, a scraper assembly 55 for scraping away the oxide film on the surface of the tin solution is provided on one side of the tin pot 52. The scraper assembly 55 includes a scraper plate 551 and a scraper drive 552 for driving the scraper plate 551 upward and downward, and reciprocating into the tin pot 52. The scraper drive 552 preferably includes a vertically mounted cylinder and an inwardly and outwardly mounted cylinder. Furthermore, a waste tin liquid collection box 553 is detachably connected to one side of the tin pot 52 to facilitate the collection and disposal of the waste tin liquid, maintaining a clean environment and a tidy working environment.

[0041] Through the coordinated work of the above components, the tin immersion device 5 of the present invention can realize automated, efficient and high-quality tin immersion operations, greatly improving production efficiency, reducing manual intervention, and improving product consistency and reliability.

[0042] The test device 6 of the present invention provides real-time monitoring and testing capabilities, ensuring that the tinning quality of each wire pin meets standards. Specifically, the test device 6 includes a test frame 61, which is equipped with a test table 62. Several conductive pads 621 are arranged on the test table 62. These conductive pads 621 are connected via electrical cables to a test instrument for measuring coil parameters, including but not limited to coil continuity and resistance.

[0043] A push-down member 63 is located above the test bench 62. The main function of the push-down member 63 is to press the coil pins on the fixture 3 downward, causing them to contact the corresponding conductive sheet 621, thereby enabling testing. To enable the push-down member 63 to move up and down, it is connected to a push-down drive device 631 for driving it up and down. The push-down drive device 631 is preferably a pneumatic cylinder arranged in the vertical direction. This design ensures that the push-down member 63 can perform the lifting action smoothly and accurately.

[0044] Furthermore, in order to ensure precise contact between the coil pins and the conductive sheet 621, a positioning fork 64 for fine-tuning the inner and outer positions of the coils on the fixture 3 is provided above the test bench 62. The positioning fork 64 is used to make subtle adjustments to the position of the coils during the test to ensure that each coil is accurately positioned. The positioning fork 64 is connected to a fine-tuning drive device 641 for driving it to move up and down and in and out. The fine-tuning drive device 641 preferably includes a vertically arranged cylinder and an inward and outward arranged cylinder. This design can provide the positioning fork 64 with sufficient flexibility and precision to complete the fine-tuning task.

[0045] The test device 6 of the present invention, through the coordinated operation of the above components, can monitor and test the coils in real time after the tinning process. This design not only improves testing efficiency but also greatly increases the reliability and accuracy of the test, helping to ensure that the tinning quality of each coil meets high standards.

[0046] The unloading device 7 typically includes a retrieving gripper for removing coils from the fixture 3, a retrieving drive mechanism for raising and lowering the gripper and moving it in and out, preferably including a vertically mounted cylinder and an inwardly mounted cylinder, and a conveyor assembly. This unloading mechanism allows processed coils to be quickly and safely transported to the next process step, ensuring efficient operation of the entire automated tinning system.

[0047] In summary, the automatic tin immersion equipment of this embodiment not only realizes the full automation of the tin immersion process, improves production efficiency and product quality, but also takes into account the convenience and flexibility of operation in design, fully meeting the diverse needs of the modern electronic manufacturing industry.
