Description

Technical Field

[0001] This invention relates to the field of transformer assembly equipment technology, and more specifically to an assembly and molding equipment system for transformer production. Background Technology

[0002] In the field of transformer manufacturing, as electronic equipment develops towards miniaturization, high performance, and high reliability, increasingly higher demands are placed on the production efficiency and assembly precision of core electronic components such as transformers. Transformers are typically assembled from components such as a magnetic core, a bobbin with wound coils, and necessary insulating materials. The bobbin has coils pre-wound and inner protective tape, while the magnetic core must be precisely assembled into the center hole of the bobbin and fixed with adhesive. Subsequently, the grounding pins of the bobbin need to be bent, and outer protective tape is wrapped around the outside of the magnetic core to complete insulation protection and structural fixation. The precision, consistency, and efficiency of this series of processes directly affect the electrical performance, mechanical strength, and final product quality of the transformer.

[0003] Currently, traditional transformer assembly production relies heavily on manual labor or semi-automatic equipment. Manual assembly suffers from inherent drawbacks such as high labor intensity, low production efficiency, poor product consistency, and susceptibility to human error, making it difficult to meet the demands of large-scale, high-standard production. Existing semi-automatic or stand-alone automated equipment often only completes individual processes, such as individual core assembly, individual glue dispensing, or individual winding.

[0004] These devices often lack efficient coordination and collaboration, requiring manual material transfer, positioning, and clamping between processes. This leads to production interruptions, uncoordinated cycle times, and low overall automation. Furthermore, because the magnetic core and frame are inherently fragile, manual handling and intervention can easily cause component damage, adhesive misalignment, and inconsistent pin bending angles, thus affecting product yield.

This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0031] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1-11 As shown, an assembly and molding equipment for transformer production includes a frame 1, a core assembly station 2 in the middle of the frame 1, and a skeleton conveying mechanism 4 on the left side of the frame 1 for conveying a skeleton 3 to the core assembly station 2. The skeleton 3 is wound with a coil 5 and an inner protective tape 6. The frame 1 is provided with a conveying mechanism 7 in the middle, which can fix the skeleton 3 inside the skeleton conveying mechanism 4 and send it into the magnetic core assembly station 2; The frame 1 is symmetrically provided with magnetic core conveying mechanisms 9 on both sides of the middle section for conveying magnetic cores 8 to the magnetic core assembly station 2; The frame 1 on the front and rear sides of the magnetic core assembly station 2 is respectively equipped with a magnetic core gluing mechanism 10 for dispensing or applying glue to the central column of the magnetic core 8. The frame 1 is provided with a magnetic core assembly mechanism 11 in the middle for assembling the magnetic core 8 onto the frame 3 of the conveying mechanism 7; The first clamping mechanism 12 is provided on the frame 1 on the right side of the magnetic core assembly station 2; The frame 1 is provided with a first flipping conveying mechanism 13 for conveying the skeleton 3 with the magnetic core assembled to the first clamping mechanism 12; The frame 1 is provided with a bending mechanism 15 for bending the grounding pins 14 of the skeleton 3 located in the first clamping mechanism 12. The frame 1 on the right side of the first clamping mechanism 12 is provided with a dispensing and wrapping mechanism 17 that can dispense glue to the grounding pin 14 after bending and wrap an outer protective tape 16 around the outside of the magnetic core 8. The frame 1 is provided with a second flipping conveyor mechanism 17 for feeding the skeleton 3 processed by the bending mechanism 15 into the dispensing and wrapping mechanism 17.

[0033] In this invention, the skeleton 3, which is pre-wound with coil 5 and inner protective tape 6, is transported one by one to the right side of the frame 1 by the skeleton conveying mechanism 4, and then sent to the magnetic core assembly station 2 by the conveying mechanism 7. A magnetic core 8 is conveyed into the magnetic core assembly mechanism 11 by the magnetic core conveying mechanism 9 on both sides of the magnetic core assembly station 2, and the magnetic core glue application mechanism 10 applies glue or adhesive to the end face of the central column of the magnetic core 8. Then, the magnetic core assembly mechanism 11 is controlled to push the glued magnetic core 8 onto the skeleton 3 on the conveying mechanism 7, and the central column of the magnetic core 8 is inserted into the central hole of the skeleton 3 and they are connected and bonded together.

[0034] The first flipping conveyor 13 sends the skeleton 3 with the magnetic core 8 into the first clamping mechanism 12, controls the first clamping mechanism 12 to fix the skeleton 3, and then controls the bending mechanism 15 to work, bending the grounding pin 14 of the skeleton 3 downward and pressing it forward in sequence. After the bending process is completed, the material is fed into the fixture of the dispensing and wrapping mechanism 17 through the second flipping conveyor 17. First, the dispensing and wrapping mechanism 17 is controlled to dispense glue at the grounding pin 14 after bending, and then the outer protective tape 16 is wrapped around the outside of the magnetic core 8.

[0035] This invention achieves fully automated operation from skeleton feeding, magnetic core feeding, gluing, assembly, pin bending to outer protective tape wrapping through the coordinated cooperation of the skeleton conveying mechanism, magnetic core conveying mechanism, conveying mechanism, and flipping conveying mechanism. Each workstation is tightly connected, requiring no manual intervention for handling and positioning, enabling continuous cyclical production. This significantly reduces the assembly time per unit, increasing production efficiency several times compared to traditional manual or semi-automatic methods.

[0036] This invention employs a centralized core assembly station, utilizing a dedicated core gluing mechanism to achieve precise gluing of the central column, and a core assembly mechanism to press and connect the core to the frame. The entire process is guided and positioned by mechanical mechanisms, avoiding problems such as uneven glue application and alignment deviations caused by manual operation, ensuring the strength and consistency of the core bonding, and improving the stability of the product's electrical performance.

[0037] By incorporating a first clamping mechanism and a bending mechanism, the grounding pin can be automatically bent twice (downward bending and forward pressing). The bending angle and position are controllable, avoiding stress damage or inconsistent angles caused by manual bending. Subsequently, an adhesive dispensing and wrapping mechanism applies adhesive to the bending points for fixation, and outer protective tape is automatically wrapped around the outside of the magnetic core. This achieves continuous insulation protection and structural reinforcement, significantly improving the mechanical strength and long-term reliability of the transformer product.

[0038] See Figures 1-3 The skeleton conveying mechanism 4 of the present invention includes a skeleton conveying track 41 disposed on the frame 1. The feed end on the left side of the skeleton conveying track 41 is connected to the skeleton conveying vibratory plate 42. An interception support frame 43 is disposed on the discharge end on the right side of the skeleton conveying track 41. An interception plate 44 is hinged to the interception support frame 43. An interception motor 45 is disposed on the interception support frame 43. A toggle plate 46 that can rotate the interception plate 44 upward to open is disposed on the output shaft of the interception motor 45.

[0039] In this invention, the skeleton 3 arranged in a predetermined direction is conveyed to the skeleton conveying track 41 by the skeleton conveying vibratory plate 42, and the opening and closing of the intercepting plate 44 is controlled by the intercepting motor 45 to control the rotation of the actuating plate 46, thereby realizing the discharge of materials one by one.

[0040] See Figures 3-4The conveying mechanism 7 of the present invention includes a first through groove 71 disposed on the frame 1, a movable frame 72 disposed in the first through groove 71, limit seats 90 disposed on the left and right sides of the upper end face of the movable frame 72, clamping plates 74 disposed on the front and rear sides of the movable frame 72, guide rods 75 disposed at corresponding positions of the clamping plates 74 and the limit seats 90, the guide rods 75 being movably disposed within the limit seats 90, a transmission rack 76 disposed on the inner side of the clamping plates 74, a rotary motor 77 disposed on the lower end face of the movable frame 72, the output axis of the rotary motor 77 extending upward through the movable frame 72 and a drive gear 78 disposed thereon, the drive gear 78 meshing with the transmission rack 76, and a first cylinder 79 disposed in the frame 1, the telescopic shaft of the first cylinder 79 being connected to the movable frame 72.

[0041] In this invention, a hinge frame 18 is provided on the frame 1, and a positioning pressure rod 19 is provided on the hinge frame 18 via a hinge shaft. A pressing vertical rod 20 is provided on the front end of the positioning pressure rod 19. A second cylinder 21 is provided on the frame 1, and the telescopic shaft of the second cylinder 21 is connected to the rear end of the positioning pressure rod 19. The pressing vertical rod 20 can press against the skeleton 3 in the conveying mechanism 7, thereby ensuring that the skeleton 3 maintains accurate positioning during the assembly of the magnetic core and subsequent processes, and will not shift.

[0042] See Figure 3 and 5 -6. The magnetic core assembly mechanism 11 of the present invention includes assembly cylinders 111 symmetrically arranged on the front and rear sides of the magnetic core assembly station 2. A pusher seat 112 capable of carrying the magnetic core 8 conveyed by the magnetic core conveying mechanism 9 is provided on the telescopic shaft of the assembly cylinders 111. The pusher seat 112 in the present invention includes a vertical plate 1121, and a bearing protrusion 1122 is provided on the lower inner side of the vertical plate 1121.

[0043] See Figures 2-35. The magnetic core conveying mechanism 9 of the present invention includes a magnetic core conveying track 91 disposed on a frame 1. The feed end of the magnetic core conveying track 91 is connected to a magnetic core vibrating plate 92, and the discharge end of the magnetic core conveying track 91 is vertically downward. Limit seats 90 are respectively disposed on the left and right sides of the discharge end of the magnetic core conveying track 91. A positioning plate 93 is disposed on the frame 1 outside the limit seats 90. A guide hole 94 is disposed on the positioning plate 93, and a movable part is disposed in the guide hole 94. A guide rod 95 is provided, and an intercepting seat 96 is provided on the inner side of the guide rod 95. An intercepting head 97 that can be inserted between two limiting seats 90 is provided on the inner side of the intercepting seat 96. A top pressure spring 98 is sleeved on the outer wall of the guide rod 95 between the intercepting seat 96 and the positioning plate 93. A clearance hole 99 is provided in the middle of the intercepting seat 96 and the positioning plate 93 respectively. The telescopic shaft of the assembly cylinder 111 is movably disposed in the clearance hole 99. The pusher seat 112 is located inside the intercepting seat 96.

[0044] In this invention, the magnetic core vibratory feeder 92 operates to transport the magnetic core 8 forward within the magnetic core conveying track 91 in a fixed direction. The intercepting seat 96, under the action of the pressure spring 98, moves towards the limiting seat 90, causing the intercepting head 97 to insert below the discharge end of the magnetic core conveying track 91, thereby intercepting the magnetic core 8. The pusher seat 112 is initially positioned directly below the discharge end of the magnetic core conveying track 91. At this time, the pusher seat 112 presses against the intercepting head 97 or the intercepting seat 96, causing it to compress the pressure spring 98 and move outwards, opening the discharge end of the magnetic core conveying track 91. The foremost magnetic core 8 falls onto the pusher seat 112 under its own weight. When the control assembly cylinder 111 is working, the pusher seat 112 moves to the side of the magnetic core conveying mechanism 9. At this time, the intercepting head 97 or the intercepting seat 96 loses the outward pressure. Under the action of the top pressure spring 98, the intercepting head 97 is inserted directly below the discharge end of the magnetic core conveying track 91, thereby closing the discharge end of the magnetic core conveying track 91 and realizing feeding one by one.

[0045] Referring to 1-2, in a first embodiment of the magnetic core gluing mechanism 10 of the present invention, the magnetic core gluing mechanism 10 includes an oblique hole 101 disposed on one of the limiting seats 90, a gluing track 102 disposed on the frame 1, a gluing slider 103 movably disposed on the gluing track 102, a first dispensing pump 104 disposed on the gluing slider 103, a first injection tube 105 disposed on the first dispensing pump 104, the first injection tube 105 being movably disposed within the oblique hole 101, a gluing cylinder 106 disposed on the frame 1, and the telescopic shaft of the gluing cylinder 106 being connected to the gluing slider 103 via a connecting rod 107.

[0046] In this embodiment, the glue-applying cylinder 106 can be controlled to operate, driving the glue-applying slider 103 to move the first glue-applying pump 104 and the first glue-applying tube 105. The glue-applying end of the first glue-applying tube 105 is inserted into the oblique hole 101 and extends toward the central column end face of the magnetic core 8, thereby enabling glue to be applied to the cylindrical end face.

[0047] See figure. In a second embodiment of the magnetic core gluing mechanism 10 of the present invention, the magnetic core gluing mechanism 10 includes a second through groove 108 disposed on the frame 1, an assembly seat disposed in the second through groove 108, a transmission gear 1010 disposed in the assembly seat via a rotating shaft, a flipping seat 1011 disposed on the side of the transmission gear 1010, a flipping rod 1012 disposed on the flipping seat 1011, a glue applicator 1013 disposed at the end of the flipping rod 1012, and a drive rack 1015 disposed on the telescopic shaft of the assembly cylinder 111 via a connecting rod 1014, the drive rack 1015 meshing with the transmission gear 1010.

[0048] In this embodiment, the initial state of the adhesive coating tray 1013 is vertically arranged. When the magnetic core 8 falling from the magnetic core conveying mechanism 9 enters the pusher seat 112, the central column end face of the magnetic core 8 contacts the adhesive coating tray 1013, thereby uniformly applying a layer of adhesive to the central column end face of the magnetic core 8. When the telescopic axis of the assembly cylinder 111 extends to the magnetic core assembly station 2, the drive rack 1015 drives the transmission gear 1010 to rotate, thereby causing the flipping rod 1012 to flip the adhesive coating tray 1013 towards the magnetic core assembly station 2 and fall into the second through groove 108. After the drive rack 1015 passes the transmission gear 1010, the adhesive coating tray 1013 remains stationary in the second through groove 108. When the telescopic axis of the assembly cylinder 111 retracts in the opposite direction, the drive rack 1015 meshes with the transmission gear 1010 again, and the transmission gear 1010 rotates in the opposite direction, thereby causing the adhesive coating tray 1013 to flip upward and reset.

[0049] See Figures 8-9 The first clamping mechanism 12 of the present invention includes a third through groove 121 disposed on the frame 1, a support platform 122 disposed in the third through groove 121, clamping plates 123 disposed on the left and right sides of the support platform 122, a double-headed cylinder 124 disposed inside the frame 1, and the clamping plates 123 respectively disposed on the output shaft of the double-headed cylinder 124.

[0050] See Figures 8-9The bending mechanism 15 of the present invention includes a mounting base 151 disposed on a frame 1 on the front side of the first clamping mechanism 12, a vertical slide rail 152 disposed on the mounting base 151, a vertical slider 153 disposed on the vertical slide rail 152, a bending seat 154 disposed on the vertical slider 153, a connecting arm 155 extending rearwardly disposed on the bending seat 154, a vertical bending head 156 disposed on the connecting arm 155 that can bend the grounding pin 14 downward, a vertical cylinder 155 disposed on the mounting base 151, the telescopic shaft of the vertical cylinder 155 being connected to the bending seat 154, a horizontal cylinder 158 disposed on the frame 1 on the rear side of the first clamping mechanism 12, and a horizontal bending head 157 disposed on the telescopic shaft of the horizontal cylinder 158.

[0051] In this invention, the vertical cylinder 155 can be controlled to drive the bending seat 154 downward, causing the connecting arm 155 to drive the vertical bending head 156 downward, thus bending the grounding pin 14 of the frame 3 downward. Then, the vertical cylinder 155 can be controlled to move in the opposite direction, causing the vertical bending head 156 to return to its original position. The horizontal cylinder 158 can be controlled to operate, causing the horizontal bending head 157 to extend forward and press the bent grounding pin 14 into the groove 81 provided on the magnetic core 8.

[0052] See Figures 10-11 The dispensing and wrapping mechanism 17 of the present invention includes a rotary disk 171 movably mounted on a frame 1. A servo motor for driving the rotary disk 171 to rotate is disposed within the frame 1. Rotary clamps 172 are symmetrically arranged on the rotary disk 171. A rotary motor is disposed on the lower end face of the rotary disk 171 and connected to the rotary clamps 172. A dispensing guide rail 173 is disposed on the frame 1.

Pump 176, a second dispensing tube 177 is provided on the second dispensing pump 176, a dispensing cylinder 178 is provided on the frame 1, the telescopic shaft of the dispensing cylinder 178 is connected to the dispensing slide 174, a tape mounting turntable 179 is provided on the frame 1, an outer protective tape 22 is provided on the tape mounting turntable 179, a guide post 1710 is provided on the frame 1, the outer protective tape 22 passes around the guide post 1710 and is wound around the magnetic core 8, and a cutting mechanism 1711 is provided on the frame 1 to cut the outer protective tape 22 between the two rotating clamps 172.

[0053] In this invention, a visual inspection device can also be installed on the frame 1. The visual inspection device can detect whether there is glue at the contact point between the bending needle and the magnetic core each time. When no glue is detected, a signal is sent to the controller, and the controller controls the entire machine to stop.

[0054] In this invention, when the second flipping conveyor 17 flips and conveys the bent transformer to the rotating disk 171, the transformer falls onto the first rotating clamp 172. At this time, the second glue injection tube 177 points to the bent grounding pin 14. The glue injection cylinder 178 is controlled to move the glue injection slide 174, so that the second glue injection tube 177 contacts the bent grounding pin 14 and performs glue injection. After the glue injection is completed, the glue injection cylinder 178 is controlled to move the glue injection slide 174 in the opposite direction and exit the area of ​​the rotating disk 171. The end of the outer protective tape 22 is attached to the outer wall of the transformer core. At this time, the outer protective tape 22 is delivered to the outer wall of the second transformer core. The rotary motor is controlled to drive the first rotating clamp 172 to rotate, so that the tape can be wrapped around the outer wall of the core. After winding is completed, the tape is cut by the cutting mechanism 1711, and the end of the tape is pressed against the outer wall of the magnetic core of the second transformer. A discharge motor 23 is installed on the front frame 1, and a pneumatic discharge clamp 24 is installed on the rotating shaft of the discharge motor 23. The pneumatic discharge clamp 24 can deliver the transformer with completed tape, and a new transformer with tape is delivered through the second flipping conveyor 17. At the same time, the second rotating clamp 172 rotates to wind the tape. After completion, the rotating disk 171 is controlled to rotate 180°, and the above process is repeated to continuously wind the tape.

[0055] The cutting mechanism 1711 of this invention includes a cutting track 17111 mounted on the frame 1, a cutting slider 17112 mounted on the cutting track 17111, a blade shank 17113 mounted on the left side of the cutting slider 17112, a blade holder 17114 mounted on the left end of the blade shank 17113, a cutting blade 17115 mounted on the blade holder 17114, elastic plates 17116 mounted on the front and rear sides of the blade shank 17113, the elastic plates 17116 and the blade shank 17113 forming an acute angle, and an arc-shaped pressure head 17117 mounted on the left end of the elastic plate 17116. A cutting cylinder 17118 is mounted on the frame 1, and the telescopic shaft of the cutting cylinder 17118 is connected to the cutting slider 17112 via a connector 17119.

[0056] In this invention, the cutting cylinder 17118 can drive the cutting slider 17112 to move the cutter bar 17113 on the cutter holder 17114 to the left. The cutting blade 17115 can cut the outer protective tape 22 between the two rotating clamps 172. After cutting, under the action of the arc-shaped pressure head 17117, the outer protective tape 22 will be pressed onto the transformer that has finished winding the tape and onto the outer wall of the magnetic core of the transformer that is to be wound with tape.

[0057] In one embodiment of the present invention, a compression block 17120, capable of opening the elastic sheet 17116 outward, is movably disposed on the cutter bar 17113. An adjustment knob 17121 is screwed onto the cutter bar 17113, and a compression spring 17122 is disposed on the outer wall of the cutter bar 17113 between the adjustment knob 17121 and the compression block 17120. The present invention allows the opening degree of the elastic sheet 17116 to be adjusted by changing the position of the adjustment knob 17121, thereby enabling the arc-shaped pressure head 17117 to work effectively.

[0058] In this invention, the first flipping conveyor mechanism 13 and the second flipping conveyor mechanism 17 are both composed of a conveying motor 25 and a pneumatic conveying clamp 26, wherein the pneumatic conveying clamp 26 is disposed on the output shaft of the conveying motor 25.

[0059] This invention enables continuous, stable, and directional feeding of the coil-wound core frame, precisely positioning it to the assembly station; it achieves synchronous or sequential feeding of the two half-cores, ensuring uniform and appropriate application of adhesive to the end face of the core's central column before assembly; the glued core is precisely pressed into the central hole of the core frame, ensuring good alignment and strong adhesion. In subsequent processing, the assembled semi-finished product is smoothly transferred to the next station, and the grounding pins are precisely bent and fixed with adhesive after bending. External protective tape is neatly and tightly wrapped around the core. The entire process is automated, ensuring smooth transitions, precise positioning, and coordinated movements between processes, thereby significantly improving the efficiency, consistency, and reliability of transformer assembly, reducing reliance on manual labor, and meeting the needs of modern large-scale intelligent manufacturing.
