Description

Technical Field

[0001] This invention relates to the field of transformer tinning equipment technology, and more particularly to an automatic tinning mechanism for transformers and a transformer production line including the same. Background Technology

[0002] Tin immersion is a method of rust and corrosion prevention treatment for electronic equipment, commonly used in the manufacturing process of transformers. The principle of tin immersion is to immerse transformer components (such as iron cores and windings) in molten tin, allowing the molten tin to deposit on the surface of the components to form a protective film.

[0003] For transformer manufacturing, the exposed pins of the transformer are usually dipped in tin for sealing and protection. However, most existing tinning equipment uses pneumatic grippers to directly clamp multiple transformers into the tin bath and then wrap them with a film. In this method, the pins of transformers in adjacent positions in a group are prone to interference, and the tin liquid is prone to condensation and sticking together, affecting the subsequent transformer finishing process. To address these issues, we propose an automatic tinning mechanism for transformers and a transformer production line that includes it. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies. This invention proposes an automatic tinning mechanism for transformers and a transformer production line including the mechanism. It can ensure group-by-group tinning of transformers while avoiding interference between the bottom pins of ringing transformers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic tinning mechanism for transformers, comprising: a base platform and a material transfer track mounted on the base platform, wherein a feeding assembly, a central platform, a material lifting assembly, and a tinning assembly are sequentially fixed to the base platform along the material transfer track.

[0006] The feeding assembly includes a feeding track perpendicular to the material transfer track, a pneumatic gripper that moves servo-driven along the feeding track, and a material separating component located at the end of the feeding track. The pneumatic gripper is used to grip the transformer on the external linear rail and transfer it to the feeding track. The material separating component is used to equidistantly separate multiple transformers into a group at the end of the feeding track and servo-corresponds to the material lifting assembly.

[0007] The material lifting assembly is servo-shifted by the material transfer track. It includes a slide table slidably connected to the material transfer track, a linear module fixed on the slide table and raised and lowered by the height of the bottom table, and a clamping member located at the bottom of the slide table. The clamping member includes multiple servo-driven blade groups, each blade group corresponding to clamp one of the grouped transformers at the end of the feeding track.

[0008] The tin-immersion assembly includes a heat source, a tin bath, and a lifting component. The tin bath is used to hold molten tin, and the lifting component is used to move the tin bath away from or closer to the heat source to heat the molten tin. The position and size of the tin bath correspond to the blade assembly.

[0009] The central platform is fixed on the base platform, and a tray is provided on its top to hold the transformer after it has been dipped in tin.

[0010] Furthermore, the feeding assembly also includes an outer frame, a first slide rail fixed on the outer frame and in the same direction as the material transfer track, a first lead screw rotatably connected to the top of the outer frame, a first nut seat threadedly connected to the first lead screw, and a slide plate. The first lead screw is driven to rotate by an external motor servo. The first nut seat passes through the outer frame through an extension and is fixed to the slide plate. The slide plate is fixed with a second slide rail at the height of the outer frame and a slide block slidably connected to the second slide rail. A first cylinder is fixed to the top of the slide plate to push the slide block to slide up and down on the second slide rail. The gripper is driven by a clamping cylinder, and the clamping cylinder is connected and fixed to the slide block.

[0011] Furthermore, the feeding track includes a base, a pulley assembly, and a belt. The belt is tensioned and covers the pulley assembly. The pulley assembly is rotated by an external motor. The base also has strip blocks fixed on both sides of the top of the belt for limiting the transformer. The top of the base also has a square groove for wrapping the belt. The top of the square groove is open and the two ends of the inner wall of the opening are spaced apart from the belt. The corresponding space is used to embed the bottom pins of the transformer.

[0012] Furthermore, the material distribution component includes multiple magnetic absorbing pieces equidistantly arranged on the surface of the belt. The spacing between the magnetic absorbing pieces corresponds to the spacing between the blade groups. The magnetic absorbing pieces are used to magnetically fix the external transformer. The base is also fixed with a contact sensing block near the end of the belt. The contact sensing block is electrically connected to the feeding track to realize the positioning of the transformer after it is assembled.

[0013] Furthermore, the linear module includes a first motor, a second lead screw, a second nut seat, a third slide rail, and an intermediate platform. The first motor is fixed to the top of the slide platform, and its output end is coaxially fixed with the second lead screw. The third slide rail is arranged along the height of the slide platform. The second lead screw is rotatably connected to the slide platform and moves in the same direction as the third slide rail. The back of the intermediate platform is threadedly engaged with the second lead screw through the second nut seat. Both ends of the second nut seat are slidably connected to the third slide rail.

[0014] Furthermore, the clamping component includes a second motor, a broken rod coupling, an isolation plate, a fourth slide rail, a gear, and a rack. The second motor is fixedly connected to the intermediate platform, and its output end passes through the isolation plate via the broken rod coupling and is coaxially fixed with the gear. The fourth slide rail includes two components that are symmetrically fixed to the bottom of the isolation plate. Slider blocks are symmetrically slidably connected to both ends of the fourth slide rail. The rack includes two components that mesh with opposite ends on both sides of the gear. A misalignment plate is also fixed to the bottom end of each rack. The blade group is equidistantly fixed to the bottom of the misalignment plate.

[0015] Furthermore, each of the blade groups includes a first blade and a second blade, and the top of each second blade is connected to the bottom of the misalignment plate via a protruding connecting portion, the connecting portion being used to misalign the first blade and the second blade in height.

[0016] Furthermore, the lifting component includes a second cylinder, a guide seat, a guide rod, a third cylinder, a connecting plate, and a pressing plate. The guide rod is vertically slidably connected inside the guide seat. The guide seat includes two components and is disposed on both sides of the heat source. The output end of the second cylinder of one guide seat is fixed to one side of the solder bath through the connecting plate. The top of the second cylinder of the other guide seat is fixed with a support plate. The third cylinder is connected and fixed to the top of the support plate, and its output end is connected and fixed to the pressing plate. The pressing plate can servo-press the side of the solder bath away from the connecting plate.

[0017] A transformer production line includes the aforementioned automatic tin-dipping mechanism for transformers.

[0018] Compared with the prior art, the beneficial effects of the present invention include: using pneumatic grippers to clamp transformers on the external linear rails to the feeding rails, and then using a material separating component to equidistantly separate multiple transformers into a group at the end of the feeding rails and servo-correspond to the lifting component; subsequently, the lifting component is servo-shifted by the material transfer rails, and multiple servo-driven blade groups respectively clamp one of the transformers in the group at the end of the feeding rails; finally, the tinning component performs tinning, and while maintaining the grouping during the tinning process, each transformer can be independently separated to ensure that the bottom pins do not interfere with the clamping process and the tinning process, which is more conducive to the tinning sealing and processability.

[0025] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0026] According to one embodiment of the present invention, Figures 1-4 As shown.

[0027] Regarding the overall structure, such as Figure 1As shown, the automatic tinning mechanism for transformers includes: a base platform 2 and a material transfer track 1 mounted on the base platform 2. The base platform 2 is sequentially fixed with respect to the material transfer track 1, comprising a feeding assembly 3, a central platform 4, a lifting assembly 5, and a tinning assembly 6.

[0028] The feeding assembly 3 includes a feeding track 301 perpendicular to the track direction of the transfer track 1, a pneumatic gripper 302 that moves servo-driven along the track direction of the feeding track 301, and a material separating component 303 located at the end of the feeding track 301. The pneumatic gripper 302 is used to grip the transformer on the external linear rail and transfer it to the feeding track 301. The material separating component 303 is used to equidistantly separate multiple transformers into a group at the end of the feeding track 301 and servo-corresponds to the lifting assembly 5.

[0029] The material lifting component 5 is servo-shifted by the material transfer track 1. It includes a slide table 501 slidably connected to the material transfer track 1, a linear module 502 fixed on the slide table 501 and raised and lowered by the height of the base 2, and a clamping member 503 located at the bottom end of the slide table 501. The clamping member 503 includes multiple servo-driven blade groups 504, each blade group 504 corresponding to clamp one of the grouped transformers at the end of the feeding track 301.

[0030] The tin-immersion assembly 6 includes a heat source 601, a tin bath 602, and a lifting member 603. The tin bath 602 is used to hold molten tin, and the lifting member 603 is used to move the tin bath 602 away from or closer to the heat source 601 to heat the molten tin. The position and size of the tin bath 602 correspond to the blade assembly 504.

[0031] The central platform 4 is fixed on the base platform 2, and its top is provided with a material tray 401 to hold the transformer after tinning.

[0032] like Figures 2-4 As shown, specifically, in this embodiment, the feeding assembly 3 further includes an outer frame 304, a first slide rail 305 fixed on the outer frame 304 and in the same direction as the material transfer track 1, a first lead screw 306 rotatably connected to the top of the outer frame 304, a first nut seat 307 threadedly connected to the first lead screw 306, and a slide plate 308. The first lead screw 306 is driven to rotate by an external motor servo. The first nut seat 307 passes through the outer frame 304 through an extension and is fixed to the slide plate 308. The slide plate 308 is fixed with a second slide rail 309 at the height of the outer frame 304 and a slide block 310 slidably connected to the second slide rail 309. A first cylinder 311 is fixed to the top of the slide plate 308 to push the slide block 310 to slide up and down on the second slide rail 309. The pneumatic gripper 302 is driven by a clamping cylinder 312, and the clamping cylinder 312 is connected and fixed to the slide block 310.

[0033] The above structure enables the pneumatic gripper 302 to move in a dual-axis manner, which realizes the docking operation between the feed track 301 and the external transformer production line. The pneumatic gripper 302 can servo-grip each transformer onto the feed track 301 and then move to the corresponding end to facilitate the subsequent clamping of the clamping component 503.

[0034] Furthermore, the feeding track 301 includes a base 3011, a pulley assembly 3012, and a belt 3013. The belt 3013 is tensioned and covers the pulley assembly 3012. The pulley assembly 3012 is rotated by an external motor. The base 3011 is also fixed with strip blocks 3014 for limiting the transformer on both sides of the top of the belt 3013. The top of the base 3011 is also fixed with a square groove 3015 for wrapping the belt 3013. The top of the square groove 3015 is open and the two ends of the inner wall of the opening are spaced apart from the belt 3013. The corresponding space is used for embedding the bottom pins of the transformer.

[0035] Furthermore, the material distribution component 303 includes a plurality of magnetic absorbing pieces 3031 equidistantly arranged on the surface of the belt 3013. The spacing of the magnetic absorbing pieces 3031 corresponds to the spacing of the blade group 504. The magnetic absorbing pieces 3031 are used to magnetically fix the external transformer. The base 3011 also has a contact sensing block 3032 fixed at the end near the belt 3013. The contact sensing block 3032 is electrically connected to the feeding track 301 to realize the positioning of the transformer after it is grouped.

[0036] It is evident that in order to achieve separate clamping and tinning of grouped transformers, each transformer needs to be pre-positioned. The spacing of the magnetic chuck 3031 corresponds to the spacing of the blade group 504, so that each transformer can be clamped and lifted by the blade group 504.

[0037] Furthermore, the linear module 502 includes a first motor 5021, a second lead screw 5022, a second nut seat 5023, a third slide rail 5024, and an intermediate platform 5025. The first motor 5021 is fixed to the top of the slide platform 501, and its output end is coaxially fixed with the second lead screw 5022. The third slide rail 5024 is arranged at the height of the slide platform 501. The second lead screw 5022 is rotatably connected to the slide platform 501 and is in the same direction as the third slide rail 5024. The back of the intermediate platform 5025 is threadedly engaged with the second lead screw 5022 through the second nut seat 5023. The two ends of the second nut seat 5023 are slidably connected to the third slide rail 5024.

[0038] The linear module 502 is used to realize the displacement of the transformer after clamping in the height direction of the base platform 2, that is, the requirement in the height direction of the tinning operation.

[0039] Similarly, the clamping member 503 includes a second motor 5031, a broken rod coupling 5032, an isolation plate 5033, a fourth slide rail 5034, a gear 5035, and a rack 5036. The second motor 5031 is fixedly connected to the intermediate platform 5025, and its output end passes through the isolation plate 5033 via the broken rod coupling 5032 and is coaxially fixed with the gear 5035. The fourth slide rail 5034 includes two and is symmetrically fixed to the bottom of the isolation plate 5033. The two ends of the fourth slide rail 5034 are symmetrically slidably connected to sliders 5037. The rack 5036 includes two and meshes with the opposite ends on both sides of the gear 5035. Each rack 5036 is also fixed with a misalignment plate 5038 at its bottom end. The blade group 504 is equidistantly fixed to the bottom of the misalignment plate 5038.

[0040] Furthermore, each of the blade groups 504 includes a first blade 505 and a second blade 506. The top of each second blade 506 is connected to the bottom of the misalignment plate 5038 via a protruding connecting portion 507. The connecting portion 507 is used to misalign the first blade 505 and the second blade 506 in height.

[0041] The protruding connecting part 507 can avoid interference that may occur when the two blades are displaced relative to each other. By setting the spacing in advance, each blade group 504 can clamp a transformer on the magnetic chuck 3031, which is convenient and reliable.

[0042] Further, the lifting component 603 includes a second cylinder 6031, a guide seat 6032, a guide rod 6033, a third cylinder 6034, a connecting plate 6035, and a pressing plate 6036. The guide rod 6033 is vertically slidably connected inside the guide seat 6032. The guide seat 6032 includes two cylinders and is disposed on both sides of the heat source 601. The output end of the second cylinder 6031 of one guide seat 6032 is fixed to one side of the solder bath 602 through the connecting plate 6035. The top of the second cylinder 6031 of the other guide seat 6032 is fixed with a support plate. The third cylinder 6034 is connected and fixed to the top of the support plate, and its output end is connected and fixed to the pressing plate 6036. The pressing plate 6036 can servo-press the side of the solder bath 602 away from the connecting plate 6035.

[0043] Heating inside the solder bath 602 is achieved through the lifting component 603. The upward output of the second cylinder 6031 can move the solder bath 602 away from the heat source 601 at the bottom, avoiding excessive heating. To further ensure the stability of the immersion process, a third cylinder 6034 and a clamping block are designed on the other side of the heat source 601. The clamping block achieves hollow positioning of the solder bath 602, avoiding potential safety problems caused by shaking.

[0044] In general, the present invention uses a pneumatic gripper 302 to grip the transformer on the external linear rail and place it onto the feed rail 301. Then, the material separating component 303 separates multiple transformers into a group at equal intervals at the end of the feed rail 301 and servo-corresponds to the lifting component 5. Subsequently, the lifting component 5 is servo-shifted by the transfer rail 1 and clamps one of the transformers in the group at the end of the feed rail 301 respectively through multiple servo-driven blade groups 504. Finally, the tinning component 6 performs tinning. While maintaining the grouping during the tinning process, each transformer can be independently separated to ensure that the bottom pins do not interfere with the gripping and tinning processes, which is more conducive to the tinning sealing and processability.

[0045] Similarly, transformer production lines that include the aforementioned automatic tinning mechanism for transformers should also be within the scope of protection of this invention. Further details will not be provided here.

[0046] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
