Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to an assembly and processing equipment for transformer copper sheet groups. Background Technology

[0002] The copper lamination assembly is a key conductive component forming the transformer windings or leads. It typically consists of two copper laminations with an insulating film sandwiched between them, providing electrical connection while ensuring interlayer insulation. Its structural precision, assembly robustness, and insulation reliability directly affect the transformer's electrical performance, temperature rise control, and long-term operational safety. In mass transformer production, the efficient, precise, and stable assembly of the copper lamination assembly is crucial for ensuring product quality and production efficiency. Therefore, the industry widely employs specialized assembly and processing equipment to automate the feeding, positioning, bonding, and subsequent processing of copper laminations and insulating films, improving assembly consistency and automation levels.

[0003] Existing transformer copper sheet assembly and processing equipment (such as the structure disclosed in utility model patent CN 212874254 U) achieves multi-station continuous automatic assembly of copper sheets by setting up a processing disc, a rotating indexing disc, and feeding, bonding, tinning, and unloading units distributed around it. However, it still has a key defect in practical applications: after the stacking of the upper and lower copper sheets and the insulating film, the equipment lacks an effective auxiliary extrusion or pressing mechanism, resulting in the three-layer structure being temporarily fixed only by adhesive or surface tension, leading to insufficient tightness of the fit. During subsequent transfer, tinning, or welding processes, the insulating film is easily misaligned, wrinkled, or even detached due to vibration, temperature changes, or mechanical stress, seriously affecting the interlayer insulation performance and product yield. Utility Model Content

[0004] The purpose of this invention is to provide an assembly and processing equipment for transformer copper sheet assemblies, which solves the problem in the prior art that after the upper copper sheet, lower copper sheet and insulating film are stacked, the equipment lacks an effective auxiliary extrusion or pressing mechanism, resulting in the three-layer structure being temporarily fixed by adhesive or surface tension, and the tightness of the fit is insufficient.

[0005] To achieve the above objectives, this utility model provides an assembly and processing equipment for transformer copper sheet groups, including a workbench and a slide rail disposed on one side of the top of the workbench. A mounting frame is provided on one side of the slide rail, and a sliding seat that slides with the slide rail is connected to one side of the mounting frame. A positioning structure that is detachably connected to the top of the slide rail is provided on one side of the sliding seat. A placement plate is connected to one bottom side of the mounting frame, and a pressure plate is provided on the top of the placement plate. One side of the pressure plate is slidably connected to the inside of the mounting frame through a sliding structure. The bottom side of the pressure plate is connected to the top of the placement plate through an elastic reset structure. A pushing structure is provided on the top of the mounting frame, and the output end of the pushing structure is connected to a contact plate that contacts the top of the pressure plate.

[0006] The positioning structure includes a side plate fixedly connected to one side of the sliding seat and a positioning rod disposed on the top of the side plate and slidably passing through the side plate at one end. The top of the slide rail is provided with several positioning holes that are adapted to the positioning rod.

[0007] The sliding structure includes a vertical plate fixedly connected to one side of the top of the placement plate and a sliding groove opened on one side of the vertical plate. A lifting plate is provided on one side of the vertical plate, and a sliding rod is slidably connected inside the sliding groove. One end of the sliding rod is connected to the side wall of the lifting plate, and the other end is connected to the side wall of the pressure plate.

[0008] The sliding seat has a handle on one side, and one side of the handle is fixedly connected to the side wall of the sliding seat.

[0009] The mounting frame is fixedly connected to one side of a mounting plate, which is bolted to the top of the sliding seat.

[0010] The elastic reset structure includes a contact plate disposed at the bottom of the lifting plate and a reset spring disposed at the bottom of the contact plate. One end of the reset spring is connected to the contact plate and the other end is connected to the top of the placement plate. The pushing structure includes a pushing cylinder mounted on the top of the mounting frame. The output end of the pushing cylinder is connected to the top of the contact plate. A damper is disposed inside the reset spring.

[0011] This utility model discloses a transformer copper sheet assembly and processing equipment. The equipment effectively solves the problem of loose bonding of copper sheets caused by the lack of auxiliary pressing mechanism in the prior art by setting a pressure plate driven by a pushing structure and a corresponding elastic reset structure and contact plate in the mounting frame. After the upper copper sheet, lower copper sheet and insulating film are stacked, the pressure plate can apply stable and uniform vertical pressure to the three-layer structure, which significantly improves the interlayer bonding and avoids the phenomenon of insulation film displacement, wrinkling or falling off caused by weak adhesion or fixation by surface tension alone.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1 Please see Figure 1-5 As shown, the assembly and processing equipment for transformer copper sheet groups in this embodiment includes a workbench 1 and a slide rail 2 disposed on one side of the top of the workbench 1. A mounting frame 3 is disposed on one side of the slide rail 2. A sliding seat 4 that slides and engages with the slide rail 2 is connected to one side of the mounting frame 3. A positioning structure that is detachably connected to the top of the slide rail 2 is disposed on one side of the sliding seat 4. A placement plate 12 is connected to the bottom of one side of the mounting frame 3. A pressure plate 13 is provided on the top of the placement plate 12. One side of the pressure plate 13 is slidably connected to the inside of the mounting frame 3 through a sliding structure. The bottom side of the pressure plate 13 is connected to the top of the placement plate 12 through an elastic reset structure. A pushing structure is provided on the top of the mounting frame 3. The output end of the pushing structure is connected to a contact plate 15 that contacts the top of the pressure plate 13.

[0021] In actual operation, the assembly and processing equipment for the transformer copper sheet group first places the lower copper sheet, insulating film, and upper copper sheet to be assembled onto the placement plate 12 in sequence, completing the initial stacking and positioning. Subsequently, the mounting frame 3 slides along the slide rail 2 to the predetermined position via the sliding seat 4 connected to one side. The positioning structure between the sliding seat 4 and the slide rail 2 ensures that the mounting frame 3 is stable and does not easily shift during processing. When the stacked copper sheet group is located directly below the pressure plate 13, the pushing structure set on the top of the mounting frame 3 is activated. The pushing structure drives the contact plate 15 connected to its output end to move downward. The contact plate 15 then contacts the top of the pressure plate 13 and applies downward pressure. Under this pressure, the pressure plate 13 overcomes the elastic reset structure on its bottom side and re-establishes contact with the placement plate 12. The elastic force generated by the top connection moves vertically downward along the sliding structure inside the mounting frame 3, thereby uniformly and controllably squeezing the copper sheet assembly on the placement plate 12. This squeezing process ensures that the upper copper sheet, insulating film, and lower copper sheet are tightly bonded together, effectively expelling interlayer air and enhancing the adhesion of the adhesive or improving the physical adhesion of the glue-free structure. After the pressing is completed, the pushing structure retracts, the contact plate 15 moves upward, and the pressure plate 13 automatically returns to its initial height under the action of the elastic reset structure, preparing for the next pressing operation. Subsequently, the sliding seat 4 drives the mounting frame 3 to slide out of the workstation along the slide rail 2, making it easy for manual or robotic arms to remove the pressed copper sheet assembly for subsequent tinning or soldering processes. The entire process is simple to operate, with controllable cycle time, and is suitable for batch continuous production.

[0022] Example 2 Please see Figure 1-5 As shown, the transformer copper sheet assembly and processing equipment of this embodiment includes a positioning structure comprising a side plate 6 fixedly connected to one side of the sliding seat 4 and a positioning rod 7 disposed on the top of the side plate 6 and slidably penetrating the side plate 6 at one end. The top of the slide rail 2 is provided with a plurality of positioning holes 5 that are adapted to the positioning rod 7. Specifically, through the setting of the side plate 6, the positioning rod 7 and the positioning holes 5 on the top of the slide rail 2, when the sliding seat 4 drives the mounting frame 3 to move along the slide rail 2 to the pressing position, the operator can insert the positioning rod 7 into the corresponding positioning hole 5 to achieve quick locking between the sliding seat 4 and the slide rail 2. This effectively prevents the mounting frame 3 from shifting or shaking due to force during the pressing process and ensures that the pressure plate 13 applies pressure to the copper sheet assembly with accurate and stable positioning effect.

[0023] A handle 8 is provided on one side of the sliding seat 4. One side of the handle 8 is fixedly connected to the side wall of the sliding seat 4. Specifically, by fixing the handle 8 to the side wall of the sliding seat 4, the operator can hold the handle 8 to easily push or pull out the entire mounting frame 3 assembly, so that it can smoothly slide into or out of the working area along the slide rail 2, thereby simplifying the manual operation process, improving the efficiency of loading and unloading materials, and reducing labor intensity.

[0024] Example 3 Please see Figure 1-5 As shown, this embodiment of a transformer copper sheet assembly and processing equipment includes a sliding structure comprising a vertical plate 11 fixedly connected to one side of the top of a placement plate 12 and a sliding groove 17 formed on one side of the vertical plate 11. A lifting plate 18 is provided on one side of the vertical plate 11. A sliding rod 19 is slidably connected inside the sliding groove 17. One end of the sliding rod 19 is connected to the side wall of the lifting plate 18, and the other end is connected to the side wall of the pressure plate 13. Specifically, through the arrangement of the vertical plate 11, the sliding groove 17, the lifting plate 18, and the sliding rod 19, the pressure plate 13 is connected to the lifting plate 18 through the sliding rod 19 and is guided and slid within the sliding groove 17 on one side of the vertical plate 11. This allows the pressure plate 13 to rise and fall smoothly in the vertical direction under the drive of the pushing structure, avoiding uneven force distribution or edge warping of the copper sheet assembly due to skew during the pressing process, thereby improving the guiding accuracy and operational stability of the pressing action.

[0025] A mounting plate 9 is fixedly connected to one side of the mounting frame 3. The mounting plate 9 is bolted to the top of the sliding seat 4. Specifically, by bolting the mounting plate 9 to the top of the sliding seat 4, the mounting frame 3 is firmly connected to the sliding seat 4 through the mounting plate 9. During the pressing process, the load can be effectively transferred and the overall structural rigidity can be maintained. This avoids the position displacement of the pressure plate 13 or equipment vibration caused by loose connection, thereby enhancing the structural stability and long-term operational reliability of the equipment.

[0026] The elastic reset structure includes a contact plate 15 disposed at the bottom of the lifting plate 18 and a reset spring 14 disposed at the bottom of the contact plate 15. One end of the reset spring 14 is connected to the contact plate 15, and the other end is connected to the top of the placement plate 12. The pushing structure includes a pushing cylinder 10 mounted on the top of the mounting frame 3. The output end of the pushing cylinder 10 is connected to the top of the abutment plate 16. A damper is disposed inside the reset spring 14. Specifically, through the pushing cylinder 10, the abutment plate 16, the contact plate 15, the reset spring 14, and the reset structure, a damper is disposed inside the reset plate 14. The damper located inside the return spring 14 pushes the cylinder 10 to drive the contact plate 16 to press down the contact plate 15, which in turn drives the pressure plate 13 to apply controllable pressure to the copper sheet assembly. After pressing is completed, the return spring 14 pushes the contact plate 15 and the pressure plate 13 to automatically return to their original positions. The damper buffers the reset process, preventing the pressure plate 13 from rapidly springing up and causing impact or damage to the workpiece. This achieves the effect of stable pressing, reliable reset and gentle buffering, effectively ensuring the bonding quality of the copper sheet assembly and extending the service life of the equipment.

[0027] In actual operation, the assembly and processing equipment for the transformer copper sheet assembly first involves the operator stacking the lower copper sheet, insulating film, and upper copper sheet sequentially on the placement plate 12 to complete the initial positioning. Then, the operator holds the handle 8 fixed to the side wall of the sliding seat 4 and pushes the entire mounting frame 3 assembly along the slide rail 2 set on one side of the top of the workbench 1 into the pressing position. Once the sliding seat 4 has moved to the predetermined position, the operator inserts the positioning rod 7, which slides through the top of the side plate 6, into the corresponding positioning hole 5 on the top of the slide rail 2, thus aligning the sliding seat 4 with the slide rail. The detachable locking between 2 ensures the overall structure remains stable and does not shift during subsequent pressing. At this time, the mounting frame 3 is fixedly connected to the mounting plate 9 on one side and bolted to the top of the sliding seat 4, forming a rigid connection, effectively transmitting load and preventing loosening. Then, the push cylinder 10 installed on the top of the mounting frame 3 is activated, and its output end drives the abutment plate 16 to move downward. The abutment plate 16 presses against the contact plate 15 located at the bottom of the lifting plate 18, thereby pushing the return spring 14 connected to the contact plate 15 to compress, while simultaneously driving the pressure plate 13 to move downward. The pressure plate 13 passes through... The sliding rod 19 connected to its side wall is linked with the lifting plate 18 and achieves vertical guiding sliding in the sliding groove 17 opened on one side of the vertical plate 11. The vertical plate 11 itself is fixedly connected to the top side of the placement plate 12, thereby ensuring that the pressure plate 13 runs smoothly and without tilting during the pressing process. The pressure plate 13 applies uniform pressure to the copper sheet group on the placement plate 12, so that the upper copper sheet, insulating film and lower copper sheet are tightly attached, effectively expelling interlayer air and improving the bonding strength or physical adhesion. After pressing is completed, the cylinder 10 is pushed to retract, the contact plate 16 moves upward, and at this time it is reset. Under the elastic action, the spring 14 pushes the contact plate 15 and the pressure plate 13 to automatically reset. The damper set inside the reset spring 14 buffers the reset process to prevent the pressure plate 13 from rebounding quickly and causing impact or damage to the workpiece. After the reset is completed, the operator pulls out the positioning rod 7 and holds the handle 8 again to slide the sliding seat 4 together with the mounting frame 3 out of the work position along the slide rail 2. This makes it easy for manual or robotic arms to remove the pressed copper sheet group and enter the subsequent tinning or welding process. The whole process structure is closely coordinated, the actions are smooth and the rhythm is controllable, which is suitable for batch continuous production.

[0028] This equipment, through the organic coordination of all the above structures, comprehensively solves the problems of poor adhesion, easy detachment, and impact on insulation performance and product yield in existing technologies: the workbench 1 provides a stable foundation for the whole machine; the slide rail 2 and the sliding seat 4 form a sliding guide system, which, together with the handle 8, enables convenient entry and exit of the mounting frame 3; the positioning structure composed of the side plate 6, the positioning rod 7, and the positioning hole 5 ensures accurate locking of the position during pressing and prevents force deviation; the mounting plate 9 firmly connects the mounting frame 3 to the sliding seat 4 with bolts, enhancing the overall rigidity; the placement plate 12 serves as a copper sheet assembly support platform, and the vertical plate 11 and the sliding groove 17 set on it provide vertical guidance for the pressure plate 13; the pressure plate 13 is connected to the lifting plate 18 through the sliding rod 19, achieving stable downward pressing when the pushing cylinder 10 drives the contact plate 16 to press down the contact plate 15; the return spring 14 and the built-in damper form an elastic return buffer system, which not only ensures reliable return of the pressure plate 13 but also avoids impact damage.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
