Description

Technical Field

[0001] This utility model specifically relates to the field of rotary transformer manufacturing technology, and more specifically to a high-efficiency production line for rotary transformers. Background Technology

[0002] A rotary transformer is an electromagnetic induction sensor, mainly used to convert rotation angle or displacement into electrical signals. It has wide applications in electrical drives, aerospace, robotics and other fields. A rotary transformer mainly consists of a stator and a rotor. The working principle of a rotary transformer is based on the phenomenon of electromagnetic induction. Through the electromagnetic coupling relationship between the stator and the rotor, the mechanical rotation angle is converted into an electrical signal.

[0003] The production of rotary transformers includes rotor production, stator production, and final assembly line. The winding of the coils inside the stator is relatively labor-intensive, and an inner winding machine is generally used to quickly wind the stator coils.

[0004] However, in practice, it has been noted that the production of rotary transformers requires the workpieces to be placed in corresponding positions. Manual placement is not only labor-intensive but also time-consuming, which affects efficiency. Some production lines use robotic arms for picking up the workpieces. However, robotic arms can only pick up one workpiece at a time. In multi-station production lines, the loading time for a single robotic arm is relatively long, which affects the overall processing efficiency of the production line. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency production line for rotary transformers. Through the reciprocating movement of the feeding slide and workpiece positioning mechanism, workpieces placed on the feeding conveyor belt can be moved into the winding machine clamping assembly. Furthermore, the workpiece positioner has a through-hole corresponding to the winding machine clamping assembly, allowing for the simultaneous feeding of multiple workpieces and improving workpiece feeding efficiency. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The high-efficiency production line for rotary transformers includes a rotary transformer winding machine. A feeding conveyor belt is installed on the side of the rotary transformer winding machine, and a feeding sliding seat is movably connected to one end of the feeding conveyor belt near the rotary transformer winding machine.

[0008] The feeding sliding seat includes an L-shaped tray located above the feeding conveyor belt, and a workpiece positioner is movably connected above the L-shaped tray. A U-shaped bracket located below the feeding conveyor belt is also provided below the L-shaped tray.

[0009] Both ends of the U-shaped bracket are fixedly connected to lifting cylinders, and the ends of the lifting cylinders pass through the U-shaped bracket and are fixedly connected to both ends of the L-shaped support plate.

[0010] As a further technical solution of this utility model, the U-shaped bracket is integrally provided with a side plate at the bottom, and the side plate away from the rotary transformer winding machine is provided with symmetrical feeding cylinders, and the top of the feeding cylinders is fixedly connected to the feeding conveyor belt.

[0011] As a further technical solution of this utility model, the workpiece positioner includes an outer mounting frame that slides and engages with the upper part of the L-shaped support plate, and an inner positioning frame is arranged in a rectangular array on the inner side of the outer mounting frame, and a mounting bolt is threadedly connected to the connection between the outer mounting frame and the inner positioning frame.

[0012] As a further technical solution of this utility model, each of the positioning inner frames is provided with a through positioning hole, and the lower part of the mounting outer frame is provided with a dovetail-shaped slide groove, and the dovetail-shaped slide groove has an opening on the side near the rotary transformer winding machine.

[0013] As a further technical solution of this utility model, the L-shaped pallet is fixedly connected to a symmetrical dovetail slider on the side near the rotary transformer winding machine, and the dovetail slider slides in cooperation with the dovetail groove below the mounting frame. In addition, the side of the L-shaped pallet is also provided with an inclined shovel surface.

[0014] As a further technical solution of this utility model, the upper protective cover of the rotary transformer winding machine includes winding machine clamping components fixedly connected in a rectangular array in the rotary transformer winding machine, corresponding to the through positioning holes.

[0015] As a further technical solution of this utility model, the end of the rotary transformer winding machine near the feeding conveyor belt is also provided with a limiting protrusion to block the mounting frame, while the side of the winding machine clamping assembly away from the feeding conveyor belt is provided with an auxiliary bracket to temporarily fix the mounting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses an L-shaped pallet to push the workpiece locator above towards the rotary transformer winding machine until the L-shaped pallet moves above the winding machine clamping assembly. At this point, the side of the rotary transformer winding machine is assisted and fixed by a magnetic attraction structure. Then, when the L-shaped pallet moves to the other side, the workpiece locator does not move. As the L-shaped pallet retracts, the material in the workpiece locator falls down into the corresponding position of the winding machine clamping assembly, realizing one-time feeding of four stations, thereby improving feeding efficiency.

[0018] This utility model uses mounting bolts to fix the inner positioning frame in a rectangular array to the outer mounting frame. The inner positioning frame is provided with through positioning holes corresponding to the winding machine clamping components. The workpieces that need to be loaded are positioned to ensure that each workpiece can fall accurately into the winding machine clamping components at the designated position, thereby further improving the loading efficiency.

[0019] In this invention, when the L-shaped pallet retracts, the dovetail-shaped slider at the end of the L-shaped pallet slides in the dovetail-shaped groove below the mounting frame. When retraction is achieved, the L-shaped pallet moves first while the mounting frame remains stationary until the workpiece falls into the designated position. Then, the L-shaped pallet drives the mounting frame to move towards the feeding conveyor belt until the positioning inner frame is moved above the workpiece on the feeding conveyor belt, facilitating the next loading.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8 This utility model provides a high-efficiency production line for rotary transformers, including a rotary transformer winding machine 1. A feeding conveyor belt 3 is provided on the side of the rotary transformer winding machine 1, and a feeding sliding seat 5 is movably connected to one end of the feeding conveyor belt 3 near the rotary transformer winding machine 1.

[0032] The feeding sliding seat 5 includes an L-shaped pallet 54 located above the feeding conveyor belt 3, and a workpiece locator 6 is movably connected above the L-shaped pallet 54. A U-shaped bracket 51 located below the feeding conveyor belt 3 is also provided below the L-shaped pallet 54.

[0033] Both ends of the U-shaped bracket 51 are fixedly connected to lifting cylinders 53, and the ends of the lifting cylinders 53 pass through the U-shaped bracket 51 and are fixedly connected to both ends of the L-shaped support plate 54.

[0034] By adopting the above technical solution, the L-shaped pallet 54 pushes the workpiece locator 6 above it toward the rotary transformer winding machine 1 until the L-shaped pallet 54 moves above the winding machine clamping assembly 4. At this time, the side of the rotary transformer winding machine 1 is assisted and fixed by the magnetic attraction structure. Then, when the L-shaped pallet 54 moves to the other side, the workpiece locator 6 will not move. As the L-shaped pallet 54 retracts, the material in the workpiece locator 6 will fall into the winding machine clamping assembly 4 at the corresponding position, realizing one-time feeding of four stations, thereby improving feeding efficiency.

[0035] Furthermore, a side plate 52 is integrally provided below the U-shaped bracket 51, and a symmetrical feeding cylinder 7 is provided on the side of the side plate 52 away from the rotary transformer winding machine 1, and the top of the feeding cylinder 7 is fixedly connected to the feeding conveyor belt 3.

[0036] Furthermore, the workpiece positioner 6 includes an outer mounting frame 61 that slides and engages with the upper part of the L-shaped support plate 54, and an inner positioning frame 62 is arranged in a rectangular array on the inner side of the outer mounting frame 61, and a mounting bolt 64 is threadedly connected to the connection between the outer mounting frame 61 and the inner positioning frame 62.

[0037] More specifically, each of the inner positioning frames 62 is provided with a through positioning hole 63, and the lower part of the outer mounting frame 61 is provided with a dovetail-shaped slide groove 65, and the dovetail-shaped slide groove 65 has an opening on the side near the rotary transformer winding machine 1.

[0038] By adopting the above technical solution, the positioning inner frame 62 is fixed in a rectangular array in the mounting outer frame 61 by mounting bolts 64, and the positioning inner frame 62 is provided with through positioning holes 63 corresponding to the winding machine clamping component 4, so as to position the workpieces that need to be loaded, ensuring that each workpiece can fall accurately into the winding machine clamping component 4 at the designated position, thereby further improving the loading efficiency.

[0039] Furthermore, the L-shaped pallet 54 is fixedly connected to a symmetrical dovetail slider 55 on the side near the rotary transformer winding machine 1, and the dovetail slider 55 slides in cooperation with the dovetail groove 65 below the mounting frame 61. Moreover, the side of the L-shaped pallet 54 is also provided with an inclined shovel surface 56.

[0040] Furthermore, the rotary transformer winding machine 1 has an upper protective cover 2, and the rotary transformer winding machine 1 has winding machine clamping components 4 fixedly connected in a rectangular array to the winding machine 1, which correspond to the through positioning holes 63.

[0041] More specifically, the end of the feeding conveyor belt 3 near the rotary transformer winding machine 1 is also provided with a limiting protrusion to block the mounting frame 61, while the side of the winding machine clamping assembly 4 away from the feeding conveyor belt 3 is provided with an auxiliary bracket to temporarily fix the mounting frame 61.

[0042] By adopting the above technical solution, when the L-shaped pallet 54 retracts, the dovetail slider 55 at the end of the L-shaped pallet 54 will slide in the dovetail groove 65 below the mounting frame 61. When retraction is achieved, the L-shaped pallet 54 moves first, while the mounting frame 61 remains stationary until the workpiece falls into the designated position. Then, the L-shaped pallet 54 drives the mounting frame 61 to move towards the feeding conveyor belt 3 until the positioning inner frame 62 is moved above the workpiece on the feeding conveyor belt 3, which facilitates the next loading.

[0043] Furthermore, the feeding conveyor belt 3 includes a frame and transmission rollers movably connected at both ends, and a transmission belt is sleeved on the outside of the transmission tube. The transmission rollers are driven by a drive motor, which drives the transmission rollers to rotate. Then, the friction between the transmission rollers and the transmission belt drives the workpieces on the transmission belt to move laterally.

[0044] Furthermore, the feeding conveyor belt 3 is provided with a limiting protrusion at one end near the rotary transformer winding machine 1, which can block the mounting frame 61 when the L-shaped pallet 54 moves towards the mounting frame 61 until the L-shaped pallet 54 is moved below the mounting frame 61.

[0045] Furthermore, the winding machine clamping assembly 4 is provided with an auxiliary bracket on the side away from the feeding conveyor belt 3, and an electromagnet is embedded in the side of the auxiliary bracket. When the L-shaped pallet 54 moves above the winding machine clamping assembly 4, the mounting frame 61 is attracted to the side of the auxiliary bracket, and the mounting frame 61 is temporarily fixed.

[0046] The working principle of this utility model is as follows: In use, the workpieces are first placed in a matrix arrangement above the feeding conveyor belt 3. The conveyor belt 3 moves the workpieces to the other end. At this time, the mounting frame 61 is located above the feeding conveyor belt 3, with a certain distance between them. This continues until the workpiece is below the mounting frame 61. Then, the lifting cylinder 53 drives the upper mounting frame 61 downwards via the L-shaped support plate 54 until the positioning inner frame 62 in the mounting frame 61 is fitted onto the outside of the workpiece. At this time, the workpiece is located in the through positioning hole 63 inside the positioning inner frame 62. Then, the feeding cylinder 7 pushes the U-shaped bracket 51 forward via the side plate 52, and also drives the L-shaped support plate 54 forward. Because the end of the feeding conveyor belt 3 has a limiting protrusion, it blocks the mounting frame 61. Combined with the inclined shovel surface 56 on the side of the L-shaped support plate 54, the workpiece locator 6 and the workpiece are simultaneously moved to the U-shaped support frame 61. Above the L-shaped bracket 51, the lifting cylinder 53 pushes the L-shaped pallet 54 upward slightly until it passes the limit protrusion. Then, the L-shaped pallet 54 continues to move forward until it moves above the rotary transformer winding machine 1. At this time, the electromagnet on the side of the winding machine clamping assembly 4 attracts the edge of the mounting frame 61, temporarily fixing the mounting frame 61. Then, the L-shaped pallet 54 moves in the opposite direction. At this time, the mounting frame 61 does not move immediately. At the same time, the dovetail slider 55 at the end of the L-shaped pallet 54 slides in the dovetail groove 65 until the L-shaped pallet 54 is completely removed from below the through positioning hole 63. The workpiece in the through positioning hole 63 will fall into the winding machine clamping assembly 4 at the corresponding position for automatic feeding. Then, the L-shaped pallet 54 drives the mounting frame 61 back above the feeding conveyor belt 3 through the dovetail slider 55. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
