Description

Technical Field

[0001] The present invention relates to the technical field of transformer potting, and particularly to a multi-station high-frequency transformer potting device and method. Background Art

[0002] A transformer potting device is a special equipment used for potting and encapsulating transformers during the production process. Its main function is to evenly fill glue (such as epoxy resin or silicone rubber) into the inside or surface of the transformer to achieve the purposes of sealing, fixing, moisture-proof, anti-corrosion, and improving insulation performance. The device usually includes a glue delivery system, a vacuum degassing system, a glue injection component, and a control system, etc., which can precisely control the flow rate and position of the glue, ensure that the glue fully fills the voids inside the transformer, reduce the generation of bubbles, and thus improve the stability and durability of the transformer. Some advanced devices are also equipped with a vibration component or ultrasonic defoaming technology to further eliminate the bubbles in the glue and improve the potting quality.

[0003] For example, in the prior art with publication number CN118335498A, a multi-station high-frequency transformer potting device is disclosed. The potting device includes a potting rack, on which a horizontally placed bottom plate is provided. On the top surface of the bottom plate, a number of potting cylinders for placing high-frequency transformers are rotatably arranged in an array; a driving component is provided on the potting rack, and on the driving component, a telescopic member with a vertical telescopic direction is provided. The telescopic end of the telescopic member is fixed with a cross plate, and a number of potting components corresponding to the potting cylinders are provided on the cross plate; in the process of potting in the present invention, the transformer is driven to rotate, so that the glue is in full contact with the transformer, and the glue can enter the gaps of the transformer under the mutual impact with the transformer, thus effectively reducing the formation of bubbles and enabling the transformer to obtain better potting protection.

[0004] The problems existing in the prior art are: the potting rack and the potting cylinders are fixed, and then the glue is sprayed out through the potting nozzle. When it is closed, there is still a part of the residual glue in the potting nozzle, which is prone to glue leakage problems, and when continuously potting multiple transformers, the processing continuity is relatively low. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] The present invention provides a multi-station high-frequency transformer potting device and method, which can solve the problem of glue leakage in the prior art. The specific solutions are as follows: On the one hand, the present invention provides a multi-station high-frequency transformer potting device, which includes a conveyor belt for conveying the transformer, and a potting assembly located above the conveyor belt. The potting assembly includes a glue outlet head and a potting box. The glue outlet heads are evenly distributed around the potting box. A fixed core is arranged inside the glue outlet head, and the glue outlet head is slidably connected to the fixed core. One end of the glue outlet head extends into the potting box and is elastically connected to the inner wall of the potting box through a first spring; The outer diameter of the fixed core and the inner diameter of the glue outlet head increase towards one end of the potting box. Under the extrusion of the first spring, the inner diameter of the glue outlet head contacts the outer diameter of the fixed core, and at this time the glue outlet head is closed; A central column, a driving disk and a driving block fixed on the outer wall of the central column are arranged inside the potting box; When the glue outlet head is in a closed state, one end of the glue outlet head located inside the potting box abuts against the outer wall of the driving disk; when one end of the glue outlet head is squeezed by the driving block, the glue outlet head slides outwards towards the outside of the potting box, separating the outer diameter of the fixed core from the inner diameter of the glue outlet head, so that the glue inside the potting box flows out to pot the transformer.

[0007] Preferably, the transformers are evenly distributed in multiple rows on the conveyor belt, with several transformers arranged in each row. The number of axially distributed glue outlet heads of the potting box corresponds to the positions of the transformers in each row, and the potting box rotates as the conveyor belt runs.

[0008] Preferably, the rotation speed of the potting box is configured such that when the glue outlet head is open, its position is in the same vertical plane as the head of the transformer, and when the glue outlet head is closed, its position is in the same vertical plane as the tail of the transformer.

[0009] Preferably, a sealing ring is arranged inside the outlet end of the glue outlet head, and a rotating core is arranged at one end of the fixed core close to the outlet end of the glue outlet head. The rotating core is rotatably connected to the end of the fixed core. When the glue outlet head is closed, the sealing ring contacts the outer wall of the rotating core, completely blocking the outlet end of the glue outlet head.

[0010] Preferably, a feed cavity is formed in the middle of the central column, and one end of the feed cavity penetrates to one end of the central column and is concentrically sleeved and installed with a feed pipe.

[0011] Preferably, a second motor is arranged at one end of the conveyor belt, and the second motor can drive the conveyor belt to run. Specifically, a base is arranged below the conveyor belt. A through cavity matching the conveyor belt is arranged inside the base. Driving rollers are rotatably installed at both ends of the base. Both ends of the conveyor belt are wound around the outer walls of the driving rollers. The second motor is fixedly installed in the middle of the base. A whole circle of teeth is arranged on the inner side of the conveyor belt. The output shaft of the second motor is fixedly connected with a gear, and the gear meshes with the teeth.

[0012] Preferably, a spiral groove is formed on the outer wall of the rotating core, and a dial rod is fixedly connected to the inner wall of the glue outlet head. The open end of the dial rod is inserted into the spiral groove. When the glue outlet head slides relative to the fixed core, the dial rod can slide inside the spiral groove, thereby driving the rotating core to rotate.

[0013] Preferably, a spiral piece is fixedly connected to the outer wall of the rotating core. The spiral piece is located above the spiral groove, and the width of the spiral piece matches the distance between the fixed core and the glue outlet head. When the glue outlet head slides relative to the fixed core, the rotating core and the spiral piece can be rotated. The direction of the spiral piece is configured such that when the glue outlet head changes from the closed state to the open state, the spiral piece can generate a thrust force towards the outlet direction of the glue outlet head, and when the glue outlet head changes from the open state to the closed state, the spiral piece generates a thrust force towards the inside of the glue outlet head.

[0014] Preferably, a driving disc and a driving block are fixedly connected to the outer wall of the central column. The driving block is located at the bottom end of the driving disc, and the driving block protrudes from the circumferential contour of the driving disc. A baffle is provided at one end of the glue outlet head close to the inside of the glue filling box, and an extrusion block is provided at one end of the baffle close to the driving disc. It is configured such that when the glue outlet head rotates with the glue filling box, the extrusion block on the glue outlet head can rotate around the outer wall of the driving disc or the driving block. And when the extrusion block rotates while fitting on the outer wall of the driving disc, under the action of the first spring, the glue outlet head is in the closed state. When the extrusion block passes by the driving block, due to the protrusion of the driving block, the extrusion block and the glue outlet head move towards the outside of the glue filling box, thereby changing the glue outlet head to the open state, and the glue inside the glue filling box can be discharged from the glue outlet head to achieve the purpose of discharging glue.

[0015] On the other hand, the present invention provides a method for filling glue into a multi-station high-frequency transformer, including the following steps: S1. Transfer the transformer to the glue filling station through a conveyor belt; S2. Drive the driving block on the central column inside the glue filling box to rotate; S3. When the driving block contacts the end of the glue outlet head extending into the glue filling box, push the glue outlet head to slide towards the outside of the glue filling box against the elastic force of the first spring; S4. Separate the inner conical surface of the glue outlet head from the outer conical surface of the fixed core by sliding to form a gap for the glue liquid to flow through; S5. The glue liquid flows from the glue filling box through the gap and out of the glue outlet head to the transformer to complete the glue filling; S6. When the driving block moves away from the glue outlet head, the first spring pushes the glue outlet head to reset, so that the inner conical surface and the outer conical surface contact again to seal the flow channel.

[0016] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects: 1. The present invention realizes automatic switch control through the coordinated sliding design of the glue dispensing head and the fixed core, and only dispenses glue at the corresponding position of the transformer to avoid invalid glue filling or misoperation. This automated mechanism reduces the need for human intervention, improves the continuity and accuracy of the production line, and ensures accurate glue delivery, reducing product defective rate.

[0017] 2. The present invention forms a complete seal through the closed ring and the rotating core when the glue discharge head is closed to prevent glue from overflowing or dripping. The spiral blade design promotes the recovery of internal residual materials to avoid the accumulation of residual glue, thereby greatly reducing the risk of glue loss and environmental pollution, improving resource utilization efficiency and simplifying cleaning and maintenance work.

[0018] 3. The present invention ensures that the glue filling operation matches the movement trajectory of the transformer by the linkage rotation of the glue filling box and the conveyor belt, and triggers the opening and closing of the glue discharge head through the driving block, so as to ensure that the glue filling operation matches the movement trajectory of the transformer. The precise timing control allows the glue to evenly cover each workstation, avoids leakage or repeated operation, and improves production efficiency and product consistency.

[0019] 4. The present invention drives the internal glue to turn over by continuously rotating the glue filling box, effectively mixes the glue components, prevents precipitation or stratification, and maintains the uniformity of glue mixing, which ensures the stability of glue performance, improves the glue filling quality and product durability, and is particularly suitable for the high-precision requirements of high-frequency transformers.

[0020] 5. The spring system of the present invention provides a stable reset force to ensure that the dispensing head quickly returns to its original position and closes, thereby enhancing the reliability and durability of the device. The rotating core ball head structure prevents component deviation and maintains stable operation of the structure. This design improves the overall robustness of the equipment, reduces the failure rate, and extends the service life, making it suitable for long-term continuous production environments.

Detailed implementation manners

[0024] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to illustrate the principle of the present invention.

[0025] Embodiment 1: As shown in Figure 1 、 Figure 2 , this embodiment provides a multi-station high-frequency transformer glue filling device, including a conveyor belt 1 for conveying the transformer 2, and a glue filling assembly located above the conveyor belt 1. The glue filling assembly includes a glue outlet head 3 and a glue filling tank 4. The glue outlet heads 3 are evenly distributed around the glue filling tank 4. A fixed core 5 is arranged inside the glue outlet head 3, and the glue outlet head 3 is slidably connected to the fixed core 5.

[0026] As shown in Figure 3 、 Figure 4 , one end of the glue outlet head 3 extends into the glue filling tank 4 and is elastically connected to the inner wall of the glue filling tank 4 through a first spring 6. Through the default extrusion force of the first spring 6, the glue outlet head 3 can be kept in a state of not discharging glue.

[0027] As shown in Figure 4As shown, the outer diameter of the fixed core 5 and the inner diameter of the glue outlet head 3 increase towards one end of the glue filling tank. Under the extrusion of the first spring 6, the inner diameter of the glue outlet head 3 contacts the outer diameter of the fixed core 5, and at this time, the glue outlet head 3 is closed. The specific configuration is as follows: an outer inclined surface 5a is provided at one end of the fixed core 5 away from the glue filling tank 4, and an inner inclined surface 3a is provided at one end of the glue outlet head 3 away from the glue filling tank 4. Since the fixed core 5 is stationary, when the glue outlet head 3 approaches the glue filling tank 4, the inner inclined surface 3a can contact the outer inclined surface 5a, so that the glue in the glue filling tank 4 cannot be discharged from the glue outlet head 3, achieving the effect of closing the glue outlet head 3. When the glue outlet head 3 moves away from the glue filling tank 4, the inner inclined surface 3a can be separated from the outer inclined surface 5a, so that a gap is generated between the glue outlet head 3 and the fixed core 5, and the glue can be discharged from the glue outlet head 3, achieving the purpose of discharging glue.

[0028] As Figure 4 , Figure 5 shown, a central column 7 is provided inside the glue filling tank 4. An outer wall of the central column 7 is fixedly connected with a driving disk 8 and a driving block 9. The driving block 9 is located at the bottommost end of the driving disk 8, and the driving block 9 protrudes from the circumferential contour of the driving disk 8. A baffle 10 is provided at one end of the glue outlet head 3 close to the inside of the glue filling tank 4, and an extrusion block 11 is provided at one end of the baffle 10 close to the driving disk 8.

[0029] In the above solution, the extrusion block 11 is located below the driving disk 8. Since the driving disk 8 and the driving block 9 are fixed on the central column 7, when the glue outlet head 3 rotates with the glue filling tank 4, the extrusion block 11 on the glue outlet head 3 can rotate around the outer wall of the driving disk 8 or the driving block 9. And when the extrusion block 11 rotates while fitting on the outer wall of the driving disk 8, under the action of the first spring 6, the glue outlet head 3 is in a closed state. When the extrusion block 11 passes by the driving block 9, due to the protrusion of the driving block 9, the extrusion block 11 and the glue outlet head 3 move towards the outside of the glue filling tank 4, so that the glue outlet head 3 changes to an open state, and the glue inside the glue filling tank 4 can be discharged from the glue outlet head 3, achieving the purpose of discharging glue.

[0030] As Figure 5 shown, as a possible embodiment, the transformers 2 are evenly distributed in multiple rows on the conveyor belt, and several transformers 2 are provided in each row. The number and positions of the glue outlet heads 3 axially distributed on the glue filling tank 4 correspond to the number and positions of the transformers 2 in each row, and the glue filling tank 4 rotates as the conveyor belt 1 operates.

[0031] As Figure 1 , Figure 2As shown in the figure, both ends of the glue filling box 4 are rotatably connected to the side walls of the support frame. One end of the glue filling box 4 penetrates through one end of the support frame and is fixedly installed with a first motor 12. The output shaft of the first motor 12 is connected to one end of the glue filling box 4. Thus, the first motor 12 can drive the glue filling box 4 to rotate. It should be noted that one end of the central column 7 is fixedly connected to one of the side walls of the support frame, so that the central column 7 does not rotate with the rotation of the glue filling box 4.

[0032] As Figure 6 shown in the figure, as a driving method of the conveyor belt 1, a second motor 13 is provided at one end of the conveyor belt 1. The second motor 13 can drive the conveyor belt 1 to operate. Specifically: a base 14 is provided below the conveyor belt 1. A through cavity matching the conveyor belt 1 is provided inside the base 14. Driving rollers 15 are rotatably installed at both ends of the base 14. Both ends of the conveyor belt 1 are wound around the outer walls of the driving rollers 15. The second motor 13 is fixedly installed in the middle of the base 14. A whole circle of teeth 16 is provided on the inner side of the conveyor belt 1. The output shaft of the second motor 13 is fixedly connected with a gear 17. The gear 17 meshes with the teeth 16. Thus, when the second motor 13 is started, the conveyor belt 1 can be driven to operate, and the rotation speeds of the second motor 13 and the first motor 12 can be adjusted according to the viewing angle requirements, so that the glue discharging timing of the glue discharging head 3 matches the position of the transformer 2.

[0033] It should be noted that the rotation speed of the glue filling box 4 is configured such that when the position of the glue discharging head 3 is opened, it is in the same vertical plane as the head of the transformer 2, and when the aforementioned glue discharging head 3 is closed, its position is in the same vertical plane as the tail of the aforementioned transformer 2, thereby completing the glue filling work of a single transformer 2.

[0034] As Figure 7 shown in the figure, as a possible embodiment, a sealing ring 18 is provided inside the outlet end of the glue discharging head 3. One end of the fixed core 5 close to the outlet end of the glue discharging head 3 is provided with a rotating core 19. The rotating core 19 is rotatably connected to the end of the fixed core 5. The rotating structure is a semi-circular ball head rotating structure (a ball head is provided at the top of the rotating core 19, and a ball groove is opened at the position corresponding to the ball head at the bottom end of the fixed core 5. The ball head can freely rotate in the ball groove, and the bottom of the ball head is a cylindrical structure, so that the rotating core 19 can only rotate around its own central axis, avoiding the deviation of the axis of the rotating core 19 from the fixed core 5). When the glue discharging head 3 is closed, the sealing ring 18 contacts the outer wall of the rotating core 19, completely blocking the outlet end of the glue discharging head 3 and preventing the overflow of surplus materials.

[0035] As Figure 7As shown, as a possible embodiment, a channel 20 is provided in the middle of the fixed core 5. The top of the channel 20 communicates with the side of the fixed core 5 through a feed port 21, and the bottom of the channel 20 communicates with the outer inclined surface 5a through a discharge port 22. It is configured that when the glue outlet head 3 is in the open state, the feed port 21 is above the baffle 10, so that the glue inside the glue filling tank 4 can enter the channel 20 from the feed port 21. When the glue outlet head 3 is in the closed state, the feed port 21 is inside the baffle 10, and the baffle 10 blocks the feed port 21, so that the glue inside the glue filling tank 4 cannot enter the channel 20 from the feed port 21.

[0036] As Figure 2 shown, in order to continuously supply glue to the glue filling tank 4, a feed cavity 23 is provided in the middle of the central column 7. One end of the feed cavity 23 close to the middle of the central column 7 communicates with the outer wall of the central column 7. One end of the feed cavity 23 penetrates to one end of the central column 7 and is coaxially sleeved and installed with a feed pipe. External glue can enter the feed cavity 23 in the middle of the central column 7 from the feed pipe, and then enter the glue filling tank 4 from the opening of the feed cavity 23.

[0037] As Figure 8 shown, a second spring 24 is also sleeved on the part of the glue outlet head 3 located outside the glue filling tank 4. One end of the second spring 24 is fixedly connected to the outer wall of the glue filling tank 4, and the other end of the second spring 24 is fixedly connected to the annular step outside the glue outlet head 3. Through this solution, the return force of the glue outlet head 3 can be made greater to ensure that the glue outlet head 3 can be completely closed.

[0038] As Figure 7 、 Figure 9 、 Figure 10 shown, a sleeve is also provided at the top of the rotating core 19. The sleeve can make the diameter of the rotating core 19 match the diameter of the fixed core 5. A spiral piece 25 is fixedly connected to the outer wall of the rotating core 19. The width of the spiral piece 25 matches the distance between the fixed core 5 and the glue outlet head 3. When the glue outlet head 3 and the fixed core 5 slide relative to each other, the rotating core 19 and the spiral piece 25 can rotate. A spiral groove 26 is also provided on the outer wall of the rotating core 19. The spiral groove 26 is adjacent to the spiral piece 25 and is located below the spiral piece 25. A dial rod 27 is fixedly connected to the inner wall of the glue outlet head 3. The open end of the dial rod 27 is inserted into the spiral groove 26. Thus, when the glue outlet head 3 and the fixed core 5 slide relative to each other, the dial rod 27 can slide inside the spiral groove 26, thereby driving the rotating core 19 to rotate.

[0039] In the above solution, the direction of the spiral piece 25 is configured such that when the glue outlet head 3 changes from the closed state to the open state, the spiral piece 25 can generate a thrust towards the outlet direction of the glue outlet head 3. When the glue outlet head 3 changes from the open state to the closed state, the spiral piece 25 generates a thrust towards the inside of the glue outlet head 3, thereby pushing the remaining material inside the glue outlet head 3 towards the inside of the glue outlet head 3, thus avoiding glue leakage.

[0040] It should be noted that in the above solution, through the continuous rotation of the glue filling tank 4, the opening and closing of the glue outlet head 3 can be cooperatively controlled. Moreover, when the glue filling tank 4 rotates itself, it can also continuously agitate the glue inside the glue filling tank 4, so that the composite glue is evenly mixed.

[0041] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that this embodiment provides a method, including the following steps: S1. Glue outlet head control: The glue outlet head is elastically connected to the inner wall of the glue filling tank through a first spring. In the default state, the spring extrusion force pushes the inner inclined surface of the glue outlet head against the outer inclined surface of the fixed core to form a sealed state (closed). The fixed core remains stationary, but the glue outlet head can move under the sliding connection. When the glue filling tank rotates, the extrusion block on the glue outlet head moves accordingly: when the outer wall of the driving disk rotates, the glue outlet head remains closed; once the extrusion block touches the driving block (protruding from the driving disk), the glue outlet head is pushed away from the glue filling tank, and the inner inclined surface and the outer inclined surface are separated to form a gap, and the glue is discharged from the gap (opened). The position of the driving block is designed to trigger opening only at the head position of the transformer, and the tail position is reset to close through the spring.

[0042] S2. Glue supply and anti-leakage: The glue flows from the feed pipe into the feed cavity of the central column and then enters the inside of the glue filling tank. When the glue outlet head is opened, the feed port on the fixed core is not blocked by the baffle, and the glue flows into the channel and is discharged from the discharge port; when closed, the baffle covers the feed port to block the glue flow. The sealing ring at the outlet end of the glue outlet head fits tightly with the rotating core to ensure complete sealing when closed. The rotating core is connected to the fixed core through a ball head structure to avoid deviation; the spiral piece and the lever drive the rotating core to rotate when the glue outlet head slides: when in the open state, the spiral piece generates an outward thrust to help the glue discharge; when closed, it generates an inward thrust to recover the remaining material to prevent leakage.

[0043] S3. Synchronization and power drive: The first motor drives the glue filling tank to rotate, and the second motor drives the conveyor belt to operate through gear teeth meshing. The speeds of the two motors are adjusted according to the principle of "aligning with the head of the transformer when the glue outlet head is opened and aligning with the tail when closed" to achieve the matching of the glue filling timing and the plumb plane of the transformer position. The rotation of the glue filling tank also evenly agitates the glue inside to avoid stratification.

[0044] In summary, the present invention realizes automatic switch control through the coordinated sliding design of the glue head 3 and the fixed core 5, and glue is only discharged at the corresponding position of the transformer to avoid invalid glue filling or misoperation. This automated mechanism reduces the need for human intervention, improves the continuity and accuracy of the production line, and ensures accurate glue delivery, reducing the product defect rate; the closed ring 18 and the rotating core 19 form a complete seal when the glue head 3 is closed to prevent glue overflow or dripping; the spiral blade 25 design promotes the recovery of internal residual materials to avoid residual glue accumulation. This greatly reduces the risk of glue loss and environmental pollution, improves resource utilization efficiency and simplifies cleaning and maintenance work; through the linkage rotation of the glue filling box 4 and the conveyor belt 1, the opening and closing of the glue head 3 is triggered by the drive block 9 to ensure that the glue filling operation matches the motion trajectory of the transformer 2, and the precise timing control allows the glue to evenly cover each workstation, avoiding leaking or repeated operations, and improving production efficiency and product consistency; the glue filling box 4 continuously rotates to drive the internal glue to turn over, effectively mix the glue components, and prevent precipitation or stratification. This ensures the stability of the glue performance, improves the quality of glue filling and the durability of the transformer 2, and is particularly suitable for the high-precision requirements of high-frequency transformers; the first spring 6 and the second spring 24 system provide a stable reset force to ensure that the glue head 3 quickly returns to its original position and closes; the ball head structure of the rotating core 19 prevents the components from deviating and maintains the stable operation of the structure. These designs improve the overall robustness of the equipment, reduce the failure rate and extend the service life, and adapt to long-term continuous production environments.
