Description

[0001] Priority of Related Applications

[0002] This application is based on the Chinese patent application No. 202211588102.0, filed on December 05, 2022, with the invention title of: An automatic production line for toughened glass insulators, and claims its priority. The entire content thereof is incorporated herein by reference. Technical Field

[0003] The present invention belongs to the technical field of glass insulators, and particularly relates to an automatic production line for toughened glass insulators. Background Art

[0004] An insulator is a special insulating control device. It is used to increase the creepage distance and is usually made of glass or ceramic, playing an important role in transmission lines. In the early years, insulators were mostly used on utility poles. However, due to the characteristics of glass insulators such as good arc resistance, good vibration resistance, not easy to age, and good self-cleaning property, it has gradually developed that a disc-shaped glass insulator is used at one end when connecting to a high-voltage wire tower. Currently, the main production process of toughened glass insulators is: batching, melting, feeding, pressing into shape, isothermal toughening, then through thermal shock, and finally packaging. Among them, the important production processes include pressing the melted material into shape and transporting the glass insulator to the specified equipment for isothermal toughening operation through a conveying device after pressing into shape.

[0005] However, in the existing production line, the glass insulator pressed into shape by the glass part mold is buckled inside the mold, and the glass part mold cannot be opened, so the manipulator cannot easily grab it. Moreover, the temperature generated in the next process of isothermal toughening is very high, and an ordinary conveyor belt cannot meet the requirements, and a conveying device made of high-temperature resistant materials is needed. However, such a conveying device often has low precision. When the manipulator grabs the glass insulator and places it on the conveying device, the insulator often slips from the conveying device to the ground. Summary of the Invention

[0006] The present invention mainly aims at the above existing problems and invents an automatic production line for toughened glass insulators. When the driving rod of the first cylinder expands and contracts, the forming mold can make an opening and closing movement around the rotating column; the adjacent driving grooves between the chain blocks cooperate with the adjacent teeth on the driving wheel, and the distance between the teeth determines the running distance of the chain, effectively improving the conveying precision when the chain runs; at the same time, the limiting cylinders and circular notches of each chain block are connected to form a chain, and when the chain turns, the limiting cylinders rotate relative to the circular notches, realizing that the chain can convey while turning.

The rotating frame 23 is formed by the cooperation of several aluminum profiles to form a double-layer hexagonal frame. There are also several height-adjustable gaskets 27 at the bottom of the rotating frame 23. Such a setting ensures the stability of the workbench surface and adjusts the overall height of the device according to the needs of different sites. In this embodiment, the rotary machine 24 can preferably be a mechanical indexing turntable, which can convert the uniform input motion of the motor into an intermittent output motion and rotates more smoothly to ensure further processing in the later stage. The top of the rotary machine 24 is fixedly connected to the first tabletop 25, and the second tabletop 26 extends upward from the first tabletop 25. When the rotary machine 24 rotates, the first tabletop 25 and the second tabletop 26 will also rotate accordingly. There are also several cylinder 1s 21 on the surface of the first tabletop 25. Except for the area of the telescopic rod, the other parts of the cylinder 1 are inside the area of the second tabletop 26. The glass solution is poured into the forming mold by other devices.

When the driving rod expands and contracts, the left mold 31 and the right mold 32 can make opening and closing movements around the rotating column 33. When the first tabletop 25 rotates, the forming mold can also rotate accordingly to adjust the position. The cooperation of the rotating action and the opening and closing action facilitates the manipulator 5 to grab. The stamping device 1 is provided on one side of the rotating device 2. The stamping device 1 is used to press the glass liquid inside the forming mold 3 into a glass part 6. The manipulator 5 is provided on the other side of the rotating device 2. The conveying device 4 is provided on one side of the manipulator 5. A clamp for clamping the glass part 6 is provided at the end of the manipulator 5.

In this embodiment, the conveying device 4 includes a guide rail 41, a chain 42, a glass part storage rack 43 and a driving device. Several support columns 3 9 are provided at the bottom of the guide rail 41.The height of the third support column 9 can be selected according to the movement range of the manipulator 5. The material of the third support column 9 is preferably made of iron material with high temperature resistance. The chain 42 is installed inside the guide rail 41. The overall shape of the guide rail 41 is U-shaped. The chain 42 is composed of a number of chain blocks 421.

A drive groove 425 is provided in the middle of each chain block 421. A second fixed platform 426 is provided at the top of the drive groove 425. The limit cylinders 422 and circular notches 423 of each chain block 421 are connected to each other to form the chain 42.

A number of balls should be provided inside the slide grooves 411. The guide rods one 424 on both sides of each chain block 421 extend into the slide grooves 411. Under the action of the balls, the guide rods one 424 are slidably connected to the slide grooves 411. A drive device is provided at the bottom of the guide rail 41. One side of the drive device is drivingly connected to the drive wheel 7. A number of gear teeth 71 are provided on the surface of the drive wheel 7. The gear teeth 71 cooperate with the drive groove 425. The glass part storage rack 43 is connected to the second fixed platform 426.

The adjacent drive grooves 425 between the chain blocks 421 cooperate with the adjacent gear teeth 71 on the drive wheel 7. When the drive wheel 7 rotates, the distance between the gear teeth 71 determines the running distance of the chain 42, thus effectively improving the conveying accuracy when the chain 42 runs. The limit cylinders and circular notches of each chain block are connected to each other to form the chain. When the chain turns, the limit cylinder 422 rotates relative to the circular notch 423, realizing that the chain 42 can convey in a curved manner.,

[0031] Such as Figure 7As shown, in this embodiment, the stamping device 1 includes a vertical rod 11, a fixing block 12, a fixing block 13, a cylinder 14, a guide rod 15 and a stamping die 16.

A guide rod 2 15 is fixedly connected to the inside of each of the cylindrical bosses, and a plurality of through holes matching the guide rod 2 15 are provided on the surface of the fixed block 2 13. The guide rod 2 15 passes through the fixed block 2 13 and is fixedly connected to the stamping die 16. The spacing between the fixed block 2 13 and the fixed block 1 12 can be adjusted according to actual needs. The four guide rods 2 15 cooperate with the stamping die 16 to ensure to a certain extent that there will be no deviation during the stamping action. When the driving shaft at the end of the cylinder 2 14 is extended and retracted, the guide rod 2 15 is vertically stamped downward under the guidance of the fixed block 2 13.

[0032] like Figure 8 As shown, in this embodiment, a driving fixed platform 8 is provided at the bottom of the guide rail 41, and the driving device includes a driving motor 81, a transmission belt 82, a transmission 83, a gear 1 84, and a transmission chain 85. The driving fixed platform 8 can preferably be made of ceramic fiber material with excellent heat insulation. The driving device is installed at the bottom of the driving fixed platform 8. The driving shaft at the end of the driving motor 81 and the transmission shaft at the end of the transmission 83 are connected by a transmission belt 82. The other end of the transmission 83 is provided with a gear 1 84. The driving shaft at one end of the driving wheel 7 is provided with a gear 2 72. The gear 1 84 and the gear 2 72 are connected by a transmission chain 85. When the driving motor 81 is working, it is transmitted to the transmission 83 through the transmission belt 82. The transmission 83 changes speed according to the actual conveying speed requirement of the user. After the speed change, the gear 1 84 on the other side of the transmission 83 rotates, and the gear 1 84 drives the transmission chain 85 to rotate the gear 2 72, and the gear 2 72 drives the driving wheel 7 to rotate.

[0033] like Figure 9 As shown, in this embodiment, a clamp 51 and a clamp 52 are provided at the end of the manipulator 5, and the shapes of the clamp 51 and the clamp 52 are symmetrical to each other. Rectangular through holes are provided on the outside of the clamp 51 and the clamp 52, and inclined surfaces for fitting the glass piece 6 are provided inside the clamp 51 and the clamp 52. The height of the rectangular through hole is greater than or equal to the height of the glass piece 6. The clamp 51 and the clamp 52 can be opened and closed under the action of the cylinder inside the manipulator to clamp the glass piece 6.

[0034] like Figure 10As shown, in this embodiment, the glass part storage rack 43 includes a first support column 431, a second support column 432, a support piece 433, a storage plane 434, and a storage boss 435.

A storage boss 435 is arranged on the surface of the storage plane 434. The storage boss 435 is composed of four arc-shaped pieces. The inside of the arc-shaped piece is an inclined arc surface, and the bottom is a plane. Separating the arc-shaped pieces is beneficial to the glass part 6 being heated evenly during the isothermal toughening operation.

[0035] Working principle and usage process of the present invention:

[0036] The present invention mainly relates to pressing and conveying in the production process of glass insulators. During pressing and forming, the already produced glass solution is poured into the forming die 3 arranged on the surface of the first table 25. The rotary machine 24 rotates, and the first table 25 will also rotate accordingly. When it rotates to the working area of the stamping device 1, the rotary machine 24 stops rotating. Then, the drive shaft at the end of the second cylinder 14 extends, and the second guide rod 15 vertically presses downward under the guiding action of the second fixing block 13 until the stamping die 16 and the forming die 3 cooperate. After stamping is completed, a glass part 6 is formed. Then, the rotary machine 2 drives the first table 25 to rotate. When it rotates to the working area of the manipulator 5, the rotary machine 24 stops rotating. The first cylinder 21 on the surface of the first table 25 will retract, and the left die 31 and the right die 32 will open a certain angle around the rotating column 33. Then, the manipulator 5 rotates to the upper part of the glass part 6, and the cylinders inside the manipulator drive the first clamp 51 and the second clamp 52 to perform a closing action to clamp the glass part 6. The manipulator 5 holds the glass part 6 above the conveying device 4, and the manipulator 5 places the glass part 6 on the storage boss 435 on the glass part storage rack 43. After placement, the clamp of the manipulator 5 loosens and returns to the initial position.

[0037] During conveying, the glass part storage rack 43 is detachably installed on the second fixing platform 426 on the surface of the chain 42. The drive motor 81 is transmitted to the transmission 83 through the transmission belt 82. The transmission 83 changes the speed according to the actual conveying speed requirements of the user. After speed change, the first gear 84 on the other side of the transmission 83 rotates. The first gear 84 drives the transmission chain 85 to make the second gear 72 rotate. The second gear 72 then drives the driving wheel 7. The driving wheel 7 drives the driving groove of the chain 42, and the chain will move forward. The distance between the teeth 71 during movement determines the running distance of the chain 42, effectively improving the conveying accuracy when the chain 42 runs. During turning in the movement process, the limit cylinder 422 rotates relative to the circular notch 423, enabling the chain 42 to turn and be linearly conveyed to the isothermal toughening operation equipment.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
