Description

Technical Field

[0001] The utility model belongs to the technical field of circuit breaker assembly, and specifically relates to a striker feeding mechanism. Background Art

[0002] A circuit breaker is a switching device used in a power system, mainly used to automatically cut off the power supply in case of faults such as overload, short circuit or leakage, to protect electrical equipment and circuits. The circuit breaker consists of an operating mechanism, a contact system and an arc extinguishing device, and has overload, short circuit and leakage protection functions. It is widely used in low-voltage, medium-voltage and high-voltage power systems. Among them, the striker is an important component of the arc extinguishing device, and during assembly, it is moved to the assembly area through a feeding mechanism.

[0003] At present, the assembly work of the striker in the existing technology has the following disadvantages: The striker usually needs to be pressed into a specific shape before assembly. This pressed shape can effectively guide the arc and ensure that the circuit breaker can safely extinguish the arc during operation, thereby protecting other electrical components from damage by the arc. However, the existing striker feeding mechanisms often put the striker after stamping completed by an external stamping device into a vibrating bowl for conveying and then feeding. The traditional striker feeding and stamping forming processes are independently separated and require manual intervention, resulting in a problem of low automation degree. Therefore, a striker feeding mechanism is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the existing striker feeding mechanism, the utility model realizes a fully automated process from feeding to stamping forming and automatic transfer through the coordinated work of feeding, stamping forming and grasping, reduces manual intervention, and improves production efficiency.

A temporary storage part is arranged on the linear vibrating track. A limiting mechanism is arranged on one side of the linear vibrating mechanism, and the limiting mechanism is used to limit the striker at the temporary storage part. The grasping mechanism includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is used to clamp and place the striker at the position of the temporary storage part on the linear vibrating track to the stamping forming mechanism for stamping forming. The second clamping mechanism is used to clamp and place the striker after stamping forming on the stamping forming mechanism to the subsequent assembly working position.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The following gives specific embodiments.

[0025] Please refer to Figures 1-7 , a kind of arc striking piece feeding mechanism of the present invention includes a vibrating bowl 1. One side of the discharging port of the vibrating bowl 1 is provided with a linear vibrator mechanism 2. The linear vibrator mechanism 2 includes a linear vibrator 21, and a linear vibration track 22 is assembled on the linear vibrator 21. A grasping mechanism 4 is arranged on one side of the linear vibrator mechanism 2. A stamping and forming mechanism 3 is arranged between the working position of the linear vibrator mechanism 2 and the working position of the grasping mechanism 4. A temporary storage part 7 is arranged on the linear vibration track 22. A limiting mechanism 6 is arranged on one side of the linear vibrator mechanism 2. The limiting mechanism 6 is used to limit the arc striking piece 01 at the temporary storage part 7. The grasping mechanism 4 includes a first clamping mechanism 47 and a second clamping mechanism 48. The first clamping mechanism 47 is used to clamp and place the arc striking piece 01 at the position of the temporary storage part 7 on the linear vibration track 22 to the stamping and forming mechanism 3 for stamping and forming. The second clamping mechanism 48 is used to clamp and place the arc striking piece 01 after stamping and forming on the stamping and forming mechanism 3 to the subsequent assembly working position;

[0026] The stamping and forming mechanism 3 includes a first cylinder 32 assembled on a support plate 31. The acting end of the first cylinder 32 is assembled with an upper die 33. It also includes a lower die box 34 located directly below the upper die 33. A placement part 35 is opened on the lower die box 34. The placement part 35 is aligned with the outlet of the linear vibration track 22. An activity cavity 341 is opened in the lower die box 34. A lower die 36 is slidably arranged in the activity cavity 341. The top end of the lower die 36 extends to the outside of the lower die box 34. An upper die groove 331 is opened at the bottom end of the upper die 33. A lower die groove 361 corresponding to the upper die groove 331 is opened at the top end of the lower die 36;

[0027] A wall groove 342 is formed in the placement portion 35. A bump 012 is provided on one side of the arc ignition piece 01. The wall groove 342 is used to accommodate the bump 012. The grasping mechanism 4 includes a first sliding seat 42 assembled on a fixed frame 41. A second sliding seat 43 is slidably assembled on the first sliding seat 42. A third air cylinder 44 for driving the second sliding seat 43 to move is assembled on one side of the first sliding seat 42. An assembly seat 45 is slidably assembled on the second sliding seat 43. A fourth air cylinder 46 for driving the assembly seat 45 to move is assembled on one side of the second sliding seat 43. A first clamping mechanism 47 and a second clamping mechanism 48 are assembled on the assembly seat 45. The first clamping mechanism 47 includes a fifth air cylinder 471. Oppositely arranged two first clamping jaws 472 are assembled on the acting end of the fifth air cylinder 471. During operation, first, the blank of the arc ignition piece 01 enters the linear vibrating track 22 through the vibrating disk 1. Then the arc ignition piece 01 moves to the temporary storage portion 7. The limiting mechanism 6 limits its position. Then the third air cylinder 44 pulls the second sliding seat 43 to move, driving the assembly seat 45 and the first clamping mechanism 47 above to move. And the operation of the fourth air cylinder 46 can also drive the first clamping mechanism 47 to move in two other directions, making the first clamping jaws 472 move to the temporary storage portion 7 and clamping the blank of the arc ignition piece 01 at the temporary storage portion 7. Then the third air cylinder 44 does the opposite work, making the second sliding seat 43 drive the first clamping mechanism 47 and the blank of the arc ignition piece 01 above to move to the stamping and forming mechanism 3, and making the arc ignition piece 01 enter the placement portion 35. At this time, the first air cylinder 32 works, driving the upper die 33 to move downward. Then the upper die groove 331 contacts the stamping portion 011 on the arc ignition piece 01. The upper die 33 presses on the stamping portion 011. The upper die groove 331 and the lower die groove 361 stamp the stamping portion 011 into a specific shape. After stamping is completed, the first air cylinder 32 drives the upper die 33 to move upward.

[0028] Further, a lifting mechanism 5 is provided on one side of the support plate 31. The lifting mechanism 5 is used to lift the arc ignition piece 01 after stamping and forming to facilitate subsequent grasping. The lifting mechanism 5 includes a second air cylinder 51. A push rod 52 is assembled on the acting end of the second air cylinder 51. One end of the push rod 52 extends into the movable cavity 341. A first bevel 521 is formed at one end of the push rod 52. A second bevel 362 corresponding to the first bevel 521 is formed at the bottom end of the lower die 36. During operation, when the blank of the arc ignition piece 01 is completed stamping at the stamping and forming mechanism 3, in order to facilitate subsequent clamping of it by the second clamping mechanism 48, the second air cylinder 51 works, driving the push rod 52 to gradually insert into the movable cavity 341. The first bevel 521 contacts the second bevel 362. At the same time, the push rod 52 pushes the lower die 36 upward and drives the arc ignition piece 01 to move upward.

[0029] Further, the second clamping mechanism 48 includes a sixth cylinder 481, and two second clamping jaws 482 arranged oppositely are assembled at the acting end of the sixth cylinder 481. During operation, when the lower die 36 pushes upward and drives the arc striking piece 01 to move upward, the fourth cylinder 46 and the third cylinder 44 operate, causing the first clamping mechanism 47 and the second clamping mechanism 48 to move towards the vibrating bowl 1, so that the second clamping mechanism 48 moves to the stamping and forming mechanism 3. At this time, the first clamping mechanism 47 moves to the temporary storage part 7 again. At this time, the second clamping mechanism 48 clamps the arc striking piece 01 after stamping and forming, and at the same time, the first clamping mechanism 47 also clamps the blank of the arc striking piece 01 at the temporary storage part 7. Then, the fourth cylinder 46 and the third cylinder 44 operate again to move the second clamping mechanism 48 and the fixed arc striking piece 01 to the assembly station, and the first clamping mechanism 47 also drives the blank of the arc striking piece 01 to move to the stamping and forming mechanism 3 again. According to the above principle, the blank of the arc striking piece 01 is repeatedly fed, stamped, picked up and placed to complete the processes.

[0030] Further, the limiting mechanism 6 includes a first limiting mechanism 61 and a second limiting mechanism 62. The first limiting mechanism 61 includes a seventh cylinder 611 and a first limiting block 612 assembled at the acting end of the seventh cylinder 611. One end of the first limiting block 612 extends to one side of the advancing direction of the arc striking piece 01 at the temporary storage part 7 in the linear vibrating track 22. The second limiting mechanism 62 includes an eighth cylinder 621 and a second limiting block 622 assembled at the acting end of the eighth cylinder 621. One end of the second limiting block 622 extends to the other side of the arc striking piece 01 at the temporary storage part 7 in the linear vibrating track 22. During operation, when the blank of the arc striking piece 01 enters the linear vibrating track 22 for conveying, the seventh cylinder 611 operates to drive the first limiting block 612 to insert into the linear vibrating track 22. When the blank of the arc striking piece 01 moves to the temporary storage part 7, the first limiting block 612 blocks it. Then, the eighth cylinder 621 operates to drive the second limiting block 622 to insert into the linear vibrating track 22, block the other side of the blank of the arc striking piece 01 at the temporary storage part 7, and block the subsequent blanks of the arc striking piece 01 entering, which is convenient for the first clamping mechanism 47 to clamp the blank of the arc striking piece 01 at the temporary storage part 7.
