Description

Technical Field

[0001] This utility model relates to the field of transformer oil gap pad manufacturing technology, specifically to an automatic inserting device for milled oil gap pads. Background Technology

[0002] Oil gap spacers are an important component of transformers, typically installed between layers of the transformer windings, between discs, or between the windings and the yoke. Between winding layers and discs, they are distributed according to a specific pattern, dividing the windings into several oil channels.

[0003] Currently, the production of oil gap gaskets typically employs two processes: stamping and milling. In the milling process, many oil gap gaskets are clamped together and milled in one go. After milling, they are clamped and conveyed out by a clamping device. However, when the clamping device is released, the multiple oil gap gaskets clamped together become scattered and fall apart, requiring manual picking and threading. This results in a huge workload for workers, high labor intensity, and low production efficiency, making it impossible to meet the requirements of automated production processes.

[0004] Therefore, there is an urgent need for an automatic inserting device for milled oil gap pads to form an automated collaborative production process, avoid the milled oil gap pads from scattering everywhere, and replace manual inserting, thereby reducing labor intensity and improving production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic inserting device for milling oil gap pads, so as to solve at least one aspect of the problems and defects mentioned in the background art.

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

[0007] An automatic inserting device for milling type oil gap pads, comprising:

[0008] A feeding device, wherein a material conveying device is provided on the top of the feeding device;

[0009] A guide device is provided on one side of the material conveying device;

[0010] A material pushing device is provided on one side of the guiding device.

[0011] The automatic inserting device for milling type oil gap pads according to this scheme has at least the following technical effects:

[0012] The automatic inserting device for milled oil gap pads forms an automated and collaborative production process through a feeding device, a material conveying device, a guiding device, and a pushing device. It can automatically and accurately insert the inserting strip into the groove at the bottom of the milled oil gap pad, effectively reducing the connection time between each ring and making the production process compact and efficient.

[0013] Compared to the traditional method of conveying the pads by clamping, this device prevents multiple oil gap pads from scattering due to the clamping device loosening, effectively avoiding manual picking and replacing manual pad threading. This significantly reduces labor intensity, improves the accuracy and consistency of milling the oil gap pads, and ensures product quality.

[0014] As a further embodiment of this utility model: the feeding device includes a lifting mechanism, and a strip storage rack is provided on the top of the lifting mechanism.

[0015] Since the feeding device includes a lifting mechanism, and a strip storage rack is set on the top of the lifting mechanism, the strips can be stacked on the strip storage rack to provide sufficient material reserves for the production process, avoid production interruptions caused by frequent addition of strips, and improve the continuity and stability of production. As the strips are continuously grabbed and conveyed, the number of strips on the strip storage rack gradually decreases, and its height will also decrease accordingly. By controlling the height of the strip storage rack through the lifting mechanism, the strips are always kept in a suitable position, which makes it easy for the material conveying device to quickly grab the strips and convey them to the next process, ensuring production efficiency.

[0016] As a further embodiment of this utility model: the material conveying device includes a support frame, which is disposed on the top of the feeding device, and a transverse movement mechanism is provided on the support frame.

[0017] As a further improvement of this utility model, the transverse mechanism is provided with a flipping mechanism.

[0018] As a further embodiment of this utility model: the bottom of the flipping mechanism is provided with a gripping mechanism that can be raised and lowered, and the bottom of the gripping mechanism is provided with a suction cup.

[0019] The material conveying device includes a support frame positioned on top of the feeding device. A lateral movement mechanism is mounted on the support frame, and a tilting mechanism is mounted on the lateral movement mechanism. A gripping mechanism with suction cups is mounted at the bottom of the tilting mechanism. When it is necessary to grip the threading strip from the feeding device and convey it to the guiding device, the lateral movement mechanism moves the tilting mechanism, which in turn moves the gripping mechanism above the feeding device. The gripping mechanism then descends, causing its suction cups to contact the surface of the threading strip, adhering it to the suction cups. The gripping mechanism then rises back to its original position, and the tilting mechanism rotates it 90°. The lateral movement mechanism then moves both the tilting and gripping mechanisms towards the guiding device, conveying the threading strip to it. This completes one material conveying cycle. This allows the material conveying device to quickly and accurately complete the conveying task of the threading strip, ensuring its smooth entry into the next process and improving the timeliness and stability of material conveying.

[0020] As a further embodiment of this utility model: the guiding device includes a guide platform, on which a plurality of power rollers and a plurality of auxiliary rollers are symmetrically arranged.

[0021] As a further embodiment of this utility model: a drive motor is provided at the bottom of the guide platform corresponding to the power roller.

[0022] The guiding device includes a guide platform with several power rollers and several auxiliary rollers symmetrically arranged on it. A drive motor is installed at the bottom of the guide platform corresponding to the power rollers. The drive motor drives the symmetrical power rollers to rotate simultaneously toward the rear end of the guiding device. The material conveying device conveys the strip to the front end of the power rollers of the guiding device. The symmetrical power rollers clamp the strip, causing it to be unloaded from the material conveying device and continuously move toward the rear end of the guiding device. The auxiliary rollers assist in correcting and guiding the posture of the strip during its movement, preventing it from tilting after passing the power rollers, ensuring the correct position of the strip during its movement, improving the conveying stability of the strip, and allowing it to accurately enter the next process.

[0023] As a further improvement of this utility model, a width adjustment cylinder is provided at one end of the drive motor.

[0024] By setting a width-adjusting cylinder at one end of the drive motor, the gap width between the symmetrical power roller and the symmetrical auxiliary roller can be adjusted. This allows the power roller and auxiliary roller to adjust the width of their symmetrical gap according to the thickness of the strip, maintaining a suitable clamping force on the strip. This ensures that the power roller can drive the strip to move, avoiding gaps that are too large or too small, which would result in either too loose a clamping force and loss of conveying power or too tight a clamping force and deformation of the strip. Furthermore, this design can adapt to the conveying of strips of different thicknesses, improving the versatility and flexibility of the guiding device.

[0025] As a further embodiment of this utility model: the pushing device includes a pushing platform, and a pushing rod is provided on the top of the pushing platform.

[0026] As a further embodiment of this utility model: the top of the pusher platform is provided with stop blocks at both ends along the length of the oil gap pad block.

[0027] The pushing device includes a pushing platform with a pushing rod on top and stops at both ends along the length of the oil gap pad. When the guiding device conveys the threading strip to the pushing device and inserts it into the groove at the bottom of the oil gap pad, the pushing rod pushes the oil gap pad. Under the constraint of the stops at both ends, the threading strip generates a reaction force with the bottom of the oil gap pad, bending both ends of the threading strip so that it is embedded and tightly locked into the groove at the bottom of the oil gap pad. This completes the threading operation of the oil gap pad, ensuring the connection between the threading strip and the oil gap pad is firm and preventing the threading strip from loosening or falling off, thus improving the overall quality and stability of the oil gap pad.

[0028] This device achieves stable conveying and precise guidance of the threading strips, and can adapt to threading strips of different specifications, improving the versatility of the equipment; it ensures the correct posture and accurate position of the threading strips, guaranteeing the smooth progress of subsequent processes; it also realizes automated threading of oil gap pads, improving production efficiency; it ensures tight fit of the threaded strips, improving the quality and stability of the oil gap pads; it reduces labor costs and defect rate, ensures product consistency, and reduces production costs and maintenance difficulty.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] like Figure 1 The present invention, as shown in the embodiment, provides an automatic inserting device for milling oil gap pads, comprising: a feeding device 1, a material conveying device 2 on the top of the feeding device 1; a guiding device 3 on one side of the material conveying device 2; a pushing device 4 on one side of the guiding device 3; a plurality of inserting strips 5 stacked on the feeding device 1; and oil gap pads 6 placed on the pushing device.

[0044] Specifically, the automatic inserting device for milled oil gap pads forms an automated collaborative production process through the feeding device 1, the material conveying device 2, the guiding device 3, and the pushing device 4. It can automatically and accurately insert the inserting strip 5 into the groove at the bottom of the milled oil gap pad 6, effectively reducing the connection time between each ring and making the production process compact and efficient.

[0045] Compared to the traditional method of conveying the strip through a clamping device, this device can prevent multiple oil gap pads 6 from scattering due to the loosening of the clamping device. It can effectively avoid manual picking and replace manual strip threading, greatly reducing labor intensity, improving the accuracy and consistency of milling the oil gap pads 6, and ensuring product quality.

[0046] like Figure 1 and Figure 2 As shown, the feeding device 1 includes a lifting mechanism 11, and a strip storage rack 12 is provided on the top of the lifting mechanism 11.

[0047] Specifically, since the feeding device 1 includes a lifting mechanism 11, and a strip storage rack 12 is provided on the top of the lifting mechanism 11, by stacking the strips 5 on the strip storage rack 12, sufficient material reserves can be provided for the production process, avoiding production interruptions caused by frequent addition of strips 5, and improving the continuity and stability of production; as the strips 5 are continuously grabbed and conveyed, the number of strips 5 on the strip storage rack 12 gradually decreases, and its height will also decrease accordingly. By controlling the height of the strip storage rack 12 through the lifting mechanism 11, the strips 5 are always kept in a suitable position, so that the material conveying device 2 can quickly grab the strips 5 and convey them to the next process, ensuring production efficiency.

[0048] like Figure 1-3As shown, the material conveying device 2 includes a support 21, which is set on the top of the feeding device 1. A transverse mechanism 22 is set on the support 21, and a flipping mechanism 23 is set on the transverse mechanism 22. A gripping mechanism 24 is set at the bottom of the flipping mechanism 23, which can be raised and lowered. A suction cup 241 is set at the bottom of the gripping mechanism 24.

[0049] Specifically, the material conveying device 2 includes a support 21, which is located on top of the feeding device 1. A transverse mechanism 22 is installed on the support 21, and a flipping mechanism 23 is installed on the transverse mechanism 22. A gripping mechanism 24 is installed at the bottom of the flipping mechanism 23, and a suction cup 241 is installed at the bottom of the gripping mechanism 24. When it is necessary to grip the threading strip 5 on the feeding device 1 and convey it to the guide device 3, the transverse mechanism 22 drives the flipping mechanism 23 to move, and drives the gripping mechanism 24 at the bottom of the flipping mechanism 23 to move above the feeding device 1. At this time, the gripping mechanism 24 descends, and the suction cup 241 at its bottom abuts against the surface of the threading strip 5, so that the threading strip 5 is adsorbed on the suction cup 241. At this time, the gripping mechanism 24 rises to its original position, the flipping mechanism 23 flips the gripping mechanism 24 by 90°, and the transverse mechanism 22 begins to drive the flipping mechanism 23 and the gripping mechanism 24 to move towards the guide device 3, conveying the threading strip 5 to the guide device 3. The material conveying device 2 completes one material conveying cycle. This enables the material conveying device 2 to quickly and accurately complete the conveying task of the threading strip 5, allowing the threading strip 5 to smoothly enter the next process, thus improving the timeliness and stability of material conveying.

[0050] like Figure 1 and Figure 4 As shown, the guiding device 3 includes a guide platform 31, on which a plurality of power rollers 32 and a plurality of auxiliary rollers 33 are symmetrically arranged. A drive motor 34 is provided at the bottom of the guide platform 31 corresponding to the power rollers 32.

[0051] Specifically, the guiding device 3 includes a guiding platform 31, on which several power rollers 32 and several auxiliary rollers 33 are symmetrically arranged. A drive motor 34 is provided at the bottom of the guiding platform 31 corresponding to the power rollers 32. The drive motor 34 drives the symmetrical power rollers 32 to rotate simultaneously toward the rear end of the guiding device 3. The material conveying device 2 conveys the threading strip 5 to the front end of the power rollers 32 of the guiding device 3. The symmetrical power rollers 32 clamp the threading strip 5, so that the threading strip 5 is unloaded from the material conveying device 2 and continues to move toward the rear end of the guiding device 3. The auxiliary rollers 33 assist in correcting and guiding the posture of the threading strip 5 during its movement, preventing the threading strip 5 from tilting after passing the power rollers 32, ensuring the correct position of the threading strip 5 during its movement, improving the conveying stability of the threading strip 5, and enabling the threading strip 5 to accurately enter the next process.

[0052] Furthermore, a width adjustment cylinder 35 is provided at one end of the drive motor 34.

[0053] Specifically, by setting a width adjustment cylinder 35 at one end of the drive motor 34, the gap width between the symmetrical power roller 32 and the symmetrical auxiliary roller 33 can be adjusted. This allows the power roller 32 and the auxiliary roller 33 to adjust the width of their symmetrical gap according to the thickness of the threading strip 5, so that the power roller 32 and the auxiliary roller 33 maintain a suitable clamping force on the threading strip 5. This ensures that the power roller 32 can drive the threading strip 5 to move, avoiding gaps that are too large or too small, which would result in either too loose clamping of the threading strip 5 and loss of conveying power or too tight clamping that would cause the threading strip 5 to be squeezed and deformed. Furthermore, this design can adapt to the conveying of threading strips 5 of different thicknesses, improving the versatility and flexibility of the guiding device operation.

[0054] like Figure 4 and Figure 5 As shown, the pushing device 4 includes a pushing platform 41, a pushing rod 42 is provided on the top of the pushing platform 41, and a stop block 43 is provided at both ends of the top of the pushing platform 41 along the length direction of the oil gap pad block.

[0055] Specifically, the pushing device 4 includes a pushing platform 41, with a pushing rod 42 on the top of the pushing platform 41 and stops 43 at both ends along the length of the oil gap pad 6. When the guiding device 3 conveys the threading strip 5 to the pushing device 4 and inserts the threading strip 5 into the groove at the bottom of the oil gap pad 6 on the pushing device 4, the pushing rod 42 pushes the oil gap pad 6. Under the restriction of the stops 43 at both ends, the threading strip 5 generates a reaction force with the bottom of the oil gap pad 6, bending both ends of the threading strip 5 so that it is embedded and tightly locked in the groove at the bottom of the oil gap pad 6, thereby completing the threading operation of the oil gap pad 6, ensuring the firm connection between the threading strip 5 and the oil gap pad 6, preventing the threading strip 5 from loosening or falling off, and improving the overall quality and stability of the oil gap pad 6.

[0056] This device achieves stable conveying and precise guidance of the threading strip 5, and can adapt to different specifications of threading strip 5, improving the versatility of the equipment; ensures the correct posture and accurate position of the threading strip 5, guaranteeing the smooth progress of subsequent processes; and realizes automated operation of the oil gap pad 6 for threading, improving production efficiency; ensures tight fit of the threaded strip, improving the quality and stability of the oil gap pad 6; reduces labor costs and defect rate, ensures product consistency, and reduces production costs and maintenance difficulty.

[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
