Description

Technical Field

[0001] The utility model belongs to the field of transformer iron core manufacturing, and specifically provides automatic assembly equipment for three-dimensionally wound transformer iron cores. Background Art

[0002] The iron core plays a crucial role in the transformer manufacturing process, and its quality directly impacts the performance of the final transformer. Given the current state of the industry, on-site manual assembly using relatively simple tools remains the most common and widespread processing method. The basic process involves three workers, each controlling a core, aligning, assembling, and securing the three cores. Transport equipment then secures the assembled cores before transporting them to the next workstation.

[0003] However, in practice, due to the heavy core and the fact that amorphous alloy transformer cores are made from coiled amorphous strips with sharp edges that can easily fall apart during assembly, assembly typically requires highly skilled workers and the collaboration of multiple skilled workers to complete the assembly in one go. Furthermore, the fit and precision of the assembly process are easily affected by human factors, resulting in low product yields and high costs.

[0004] The existing production process involves a large number of people and lacks reliable equipment support, resulting in significant safety risks. Therefore, there is an urgent need to develop an automated assembly device for three-dimensionally wound transformer cores to address these issues. With this in mind, this patent application is filed. Utility Model Content

[0005] The automatic assembly equipment for three-dimensional wound transformer cores described in this application aims to solve the problems existing in the above-mentioned prior art and propose an automated assembly solution, so as to effectively improve the assembly efficiency and qualification rate, and relatively improve the operation safety while effectively reducing the processing cost.

[0006] In order to achieve the above-mentioned design purpose, the automatic assembly equipment of the three-dimensional wound transformer core includes a main rotating table, and three lifting groups are axially symmetrically distributed and connected on the top of the main rotating table; the main rotating table is composed of a bottom support fixed to the ground, and a rotating platform vertically and coaxially connected to the bottom support and used to carry the lifting group; a bottom slewing bearing assembly is connected between the bottom support and the rotating platform, and the bottom slewing bearing assembly includes a driving device arranged on the bottom support, and the driving device drives the rotating platform to rotate back and forth; a roller line driven by a motor for conveying workpieces is arranged on the rotating platform, and a slewing bearing for carrying and driving the lifting group is respectively arranged at the end and both sides of the conveying direction of the roller line; a through hole is provided at the center of the rotating platform and on the roller line, and the lifting device driven by the screw and nut assembly is respectively connected to the roller line and the pallet.

[0007] Furthermore, a group of beam-type gratings are arranged on the bottom support.

[0008] Furthermore, the three lifting groups have the same overall structure, and each lifting group consists of a transverse movement component and a jacking component.

[0009] Furthermore, a gear connected to the slewing bearing transmission is provided at the bottom of the transverse moving assembly, and a transverse moving cylinder and a transverse moving screw are arranged horizontally on the side of the transverse moving assembly. The transverse moving screw is driven by a servo motor through a synchronous belt, and the driving ends of the transverse moving cylinder and the transverse moving screw are respectively connected to the jacking assembly.

[0010] Furthermore, a linear guide rail is connected between the transverse movement assembly and the jacking assembly, and a guide rail block fixed to one side of the transverse movement assembly is slidably connected to the linear guide rail, and the guide rail block is supplied with oil by a centralized oil supply device.

[0011] Furthermore, the tops of the traverse cylinder and the traverse screw rod are respectively covered with accordion shields for protection.

[0012] Furthermore, the jacking assembly includes an upper support frame and a lower support frame arranged vertically, as well as a clamping cylinder and a jacking screw. The jacking screw is driven by a servo motor through a synchronous belt assembly. The output end of the clamping cylinder is driven and connected to the lower support frame, and the output end of the jacking screw is driven and connected to the upper support frame.

[0013] In summary, the automatic assembly equipment for three-dimensional transformer cores proposed in this application has the following advantages:

[0014] 1. A rotating mechanism is set at the bottom of the device, which reduces the original three raw material receiving points to one, lowering the requirements for raw material supply points and reducing supporting facilities, saving space and reducing costs.

[0015] 2. A light barrier is installed at the operating station to ensure that the equipment's rotation operation will not be started when someone is present, thereby ensuring personnel safety.

[0016] 3. The roller line set laterally can remove the core group after the assembly is completed. Even if the core group is not taken away and enters the next process, it will not affect the assembly of the next core, which significantly improves the assembly efficiency.

[0017] 4. The center position of the lifting device is set on the rotary axis of the main rotary table and passes through the ring of the slewing support, making the whole machine structure more compact.

[0018] 5. The top plate of the lifting device can pass through the position reserved by the roller line, ensuring the smooth fall of the iron core without increasing the volume of the device. It can also be directly removed from the top during maintenance, making inspection and maintenance more convenient.

[0019] 6. The lateral movement of the lifting group adopts the lateral movement method of cylinder and screw, which improves the movement speed without affecting the positioning accuracy, and reduces the rotation radius compared to single-layer feeding, making the equipment more flexible and reliable.

[0020] 7. The upper and lower supports of the equipment are movable, which can adapt to the assembly of cores of different specifications and models. In addition, the upper and lower supports can be controlled separately to clamp and release at different heights, thereby making the overall equipment able to adapt to different adjacent process equipment, thus improving the adaptability of the equipment.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions proposed in this application in conjunction with the above-mentioned drawings. For those skilled in the art, the described embodiments are only part of the solutions of this application and not all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without making any creative efforts should fall within the scope of protection of this application.

[0027] Example 1, as Figures 1 to 3 As shown, the automatic assembly equipment for three-dimensional winding transformer core includes a main rotating platform 1, and three lifting groups 2 axially symmetrically distributed and connected on the top of the main rotating platform 1;

[0028] The main rotating platform 1 is composed of a bottom support 11 fixed to the ground, and a rotating platform 13 vertically and coaxially connected to the bottom support 11 and used to carry the lifting group 2;

[0029] A bottom slewing bearing assembly is connected between the bottom support 11 and the rotating platform 13. The bottom slewing bearing assembly includes a driving device provided on the bottom support 11. The driving device drives the rotating platform 13 to rotate back and forth through a gear rack meshing assembly.

[0030] A roller line 12 is provided on the rotating platform 13, which is powered by a motor through a chain and is used to transport the workpiece. A slewing bearing 16 is provided at the end and both sides of the roller line 12 for carrying and driving the lifting group 2.

[0031] A through hole is provided on the drum line 12 at the center of the rotating platform 13, and a lifting device 15 driven by a screw nut assembly is connected to the drum line 12 and the tray 14 respectively;

[0032] Furthermore, a set of through-beam light barriers 17 is installed on the bottom support 11. When a worker stands on one side of the rotating platform 13, the detection signal of the through-beam light barriers 17 is blocked, triggering an alarm. The rotating platform 13 will not rotate, ensuring the worker's safety. When the worker leaves the rotating platform 13, the detection signal of the through-beam light barriers 17 is unblocked, the alarm stops, and the rotating platform 13 can rotate.

[0033] The three lifting groups 2 have the same overall structure, and each lifting group 2 is composed of a transverse moving component and a jacking component;

[0034] The bottom of the transverse moving assembly is provided with a gear connected to the slewing bearing 16 to realize the reciprocating rotation of the lifting group 2 as a whole around its vertical axis; the transverse moving cylinder 21 and the transverse moving screw 23 are arranged horizontally on the side of the transverse moving assembly. The transverse moving screw 23 is driven by a servo motor through a synchronous belt. The driving ends of the transverse moving cylinder 21 and the transverse moving screw 23 are respectively connected to the lifting assembly;

[0035] A linear guide rail is connected between the transverse moving assembly and the jacking assembly. A guide rail block fixed to one side of the transverse moving assembly is slidably connected to the linear guide rail. The guide rail block is oiled by a centralized oil supply device 24.

[0036] The tops of the transmission components such as the traverse cylinder 21 and the traverse screw rod 23 are respectively covered with accordion shields 22 for protection.

[0037] The lifting assembly includes an upper support frame 28 and a lower support frame 29, arranged vertically, as well as a clamping cylinder 25 and a lifting screw 27. The lifting screw 27 is driven by a servo motor through a synchronous belt assembly 26. The output end of the clamping cylinder 25 is driven and connected to the lower support frame 29, and the output end of the lifting screw 27 is driven and connected to the upper support frame 28, thereby achieving a change in the vertical distance between the upper and lower supports. When the operator places the iron core on the upper support frame 28, the lifting screw 27 drives the upper support frame 28 to rise to a predetermined height, and then the clamping cylinder 25 drives the lower support frame 29 downward to prevent the iron core from shifting or falling off during rotation.

[0038] Based on the structural design of the above-mentioned three-dimensional winding transformer core automatic assembly equipment, this application can realize the following core automatic assembly process:

[0039] In the initial state, the traverse cylinder 21 and traverse screw rod 23 of the lifting group 2 are all retracted;

[0040] During assembly, the main rotating platform 1 drives the three lifting groups 2 to rotate until one of the three groups reaches the designated assembly station. The upper support frame 28 of the lifting assembly is driven by the lifting screw 27 and moves to the designated height. The pressing cylinder 25 contracts upward, and the vertical distance between the upper support frame 28 and the lower support frame 29 is reduced.

[0041] Then, the traverse cylinder 21 and the traverse screw 23 extend in sequence and pass through the iron core horizontally; when the material detection signal is triggered, the clamping cylinder 25 extends downward, and the vertical distance between the upper support frame 28 and the lower support frame 29 is expanded to clamp the iron core;

[0042] Subsequently, the lateral moving assembly of the lifting group 2 retreats as a whole, and the lifting group 2 returns to the center position as a whole, completing the core clamping action;

[0043] According to the above steps, after the three lifting groups 2 have completed the core clamping action, the three lifting groups 2's lateral cylinders 21 are extended at the same time, and the three lateral screw rods 23 are extended at the same time to clamp the three cores together. After the clamps are manually fastened, the entire assembly operation is completed.

[0044] After the assembly is completed, the lifting screw 27 extends downward, the distance between the upper support frame 28 and the lower support frame 29 is reduced and moves downward, and the lifting device 15 supports the tray 14 and lifts it to carry the iron core; after the iron core is separated from the upper support frame 28, the transverse movement components of the lifting group 2 are all retracted, the lifting device 15 descends, the tray 14 is separated from the lifting device 15 and falls on the roller line 12, and the roller line 12 operates to transport the tray 14 containing the iron core out and transport the empty tray 14 back to the designated position.
