[0002] The conductive nozzle is a common accessory of the welding gun, which is installed on the welding gun elbow.

The diameter of the middle section of the conductive nozzle is larger than that of the small diameter end and the large diameter end. The conductive nozzle needs to be threaded at the small diameter end using a thread rolling machine to facilitate connection with the welding gun. When a large number of conductive nozzles are produced and processed, if manual feeding is used, it is not conducive to improving production efficiency.

[0024] Put a large number of conductive nozzles into the vibrating disk hopper 202, and the base 201 vibrates to drive the vibrating disk hopper 202 to feed. The conductive nozzles are transported along the feeding track 202a to the opening 202b and enter the material selection plate 301. After adjusting the conductive nozzles through the material selection port 302 on the material selection plate 301, they enter the arc guide plate 304. The conductive nozzles pass through the feeding track 305 and the inclined track 306 in turn along the arc guide plate 304, and finally enter the feed trough 401f through the through hole 401e-1 on the side wall of the feed block 401e to queue up. The first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e can be the MOV-02 roller-type mechanical air valve of the brand Yijia Pneumatic. After opening the first roller-type mechanical air valve 403d, the compressed gas in the gas tank enters the first cylinder 401c, and the telescopic rod of the first cylinder 401c pushes the long strip push block 401d pushes the conductive nozzle that falls from the feed trough 401f to the push trough 401b to the first feed hole 402f-2 on the top of the feeding box 402f and enters the feeding hole 402f-1. At this time, the first roller-type mechanical air valve 403d is closed. The first cylinder 401c and the second cylinder 402d use spring-type cylinders with the brand name of Kecheng Pneumatic and the model number of MSA16X10SCA. After the first cylinder 401c is de-energized, the telescopic rod automatically shrinks back to its original position under the action of the internal spring. Then the second roller-type mechanical air valve 403e is opened, and the compressed gas in the gas tank enters the second cylinder 402d. The telescopic rod of the second cylinder 402d pushes the conductive nozzle in the feeding hole 402f-1 to the external processing equipment. At this time, the second roller-type mechanical air valve 403e is closed. After the second cylinder 402d is de-energized, the telescopic rod automatically shrinks back to its original position under the action of the internal spring.

[0025] In this embodiment, the linkage assembly 403 also includes a rotating motor 403f arranged on one side of the support frame 403a, and a first gear 403f-1 is arranged at the output end of the rotating motor 403f, and a second gear 403b-1 is arranged at one end of the rotating shaft 403b passing through the support frame 403a, and a chain 403f-2 is arranged between the first gear 403f-1 and the second gear 403b-1.

[0026] After the rotating motor 403f is turned on, the rotating motor 403f drives the first gear 403f-1 to rotate, and the first gear 403f-1 drives the second gear 403b-1 at the end of the rotating shaft 403b to rotate through the chain 403f-2, thereby driving the rotating shaft 403b to rotate.

[0027] In this embodiment, the first cam 403d-1 and the second cam 403e-1 are provided at positions on the outer wall of the rotating shaft 403b corresponding to the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e. The outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 are in opposite directions. The outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 touch and open the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e alternately as the rotating shaft 403b rotates.

[0028] The first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e are roller-type mechanical air valves of the brand Yijia Pneumatic, model MOV-02. When the roller on the roller-type mechanical air valve is squeezed, the roller-type mechanical air valve opens, and when the roller is not squeezed, the roller-type mechanical air valve closes. Since the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 are in opposite directions, when the rotating shaft 403b rotates, the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 touch alternately with the rotation of the rotating shaft 403b. Open the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e to supply air to the first cylinder 401c and the second cylinder 402d, so that the telescopic rods of the first cylinder 401c and the second cylinder 402d are extended. When the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 successively separate from the rollers of the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e, the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e are closed successively, so that the first cylinder 401c and the second cylinder 402d are cut off from air.

[0029] In this embodiment, the material selection port 302 includes a front opening 302a, a middle opening 302b, and a rear opening 302c that are interconnected. The width of the front opening 302a is adapted to the small diameter end of the conductive nozzle, the width of the front opening 302a is smaller than the diameter of the large diameter end of the conductive nozzle, the width of the rear opening 302c is adapted to the large diameter end of the conductive nozzle, and the middle opening 302b is adapted to the diameter of the middle section of the conductive nozzle.

[0030] Since the small diameter end of the conductive nozzle needs to be processed into threads by external processing equipment, the small diameter end of the conductive nozzle needs to be transported forward. When the small diameter end of the conductive nozzle enters the material selection plate 301 forward, the conductive nozzle falls directly from the material selection port 302 into the arc-shaped material guide plate 304. When the small diameter end of the conductive nozzle enters the material selection plate 301 backward, since the width of the front opening 302a is smaller than the diameter of the large diameter end of the conductive nozzle, the large diameter end of the conductive nozzle is stuck at the junction of the front opening 302a and the middle opening 302b, and the small diameter end of the conductive nozzle flips downward from the rear opening 302c to the small diameter end facing forward and backward, and the entire conductive nozzle falls on the arc-shaped material guide plate 304.

[0031] In this embodiment, the bottom end of the feed block 401e is fixed to the top of the receiving block 401a through the first support block 401e-2, and limiting plates 401f-1 are respectively provided on both sides of the top of the feed trough 401f, and arc-shaped guide plates 401f-2 are respectively provided at the bottom ends of the two limiting plates 401f-1.

[0032] The conductive nozzles enter the feed trough 401f through the through hole 401e-1 in turn and queue up to be pushed into the feeding box 402f. The limit plates 401f-1 on both sides of the top of the feed trough 401f can prevent the conductive nozzles from falling from the feed trough 401f to the outside, and the arc-shaped guide plates 401f-2 at the bottom of the two limit plates 401f-1 can guide the conductive nozzles to fall into the feed trough 401f.

[0033] In this embodiment, the bottom end of the receiving block 401a is fixed to the top of the connecting workbench 100 through the second supporting block 401a-1, and a second feeding hole 401d-1 is opened at the top of the long push block 401d corresponding to the arc guide plate 401f-2.

[0034] The conductive nozzle in the feed trough 401f falls into the second feed hole 401d-1 on the long strip push block 401d under the guidance of the arc-shaped guide plate 401f-2, and the telescopic rod of the first cylinder 401c pushes the long strip push block 401d until the second feed hole 401d-1 on the long strip push block 401d is aligned with the first feed hole 402f-2 at the top of the feeding box 402f, so that the conductive nozzle in the second feed hole 401d-1 passes through the first feed hole 402f-2 into the feeding hole 402f-1 of the feeding box 402f and waits to be pushed.

[0035] In this embodiment, the top of the feeding box 402f is flush with the bottom wall of the pushing groove 401b, and a long strip-shaped limiting hole 402f-3 communicating with the feeding hole 402f-1 is provided on the top of the feeding box 402f on one side of the first feeding hole 402f-2.

[0036] The top of the feeding box 402f is flush with the bottom wall of the pushing groove 401b, which ensures that the long strip pushing block 401d can be pushed to the top of the feeding box 402f.

[0037] In this embodiment, a block 402f-4 passing through the long strip limiting hole 402f-3 is provided on the top of the telescopic rod of the second cylinder 402d located in the feeding hole 402f-1, and a second baffle 402f-5 is provided on the outer wall of the telescopic rod of the second cylinder 402d located outside the feeding hole 402f-1. A spring 402f-6 is sleeved on the outer wall of the telescopic rod of the second cylinder 402d, and the spring 402f-6 is located between the feeding box 402f and the second baffle 402f-5.

[0038] In this embodiment, a third baffle 402b-1 is disposed at one end of the slide rail 402b away from the mounting plate 402c.

[0039] When the telescopic rod of the second cylinder 402d is extended, since the spring 402f-6 is located between the feeding box 402f and the second baffle 402f-5, the feeding box 402f is first pushed to move under the elastic force of the spring 402f-6, until the sliding block 402e at the bottom end of the feeding box 402f is blocked by the third baffle 402b-1, the telescopic rod of the second cylinder 402d continues to extend and squeezes the spring 402f-6 through the second baffle 402f-5, and the telescopic rod of the second cylinder 402d pushes the conductive nozzle in the feeding hole 402f-1 of the feeding box 402f, and sends the conductive nozzle to the external processing location. After the second cylinder 402d is cut off, the telescopic rod of the second cylinder 402d returns to its original position. During the process, the telescopic rod supports the long strip limiting hole 402f-3 through the block 402f-4 and then pulls the feeding box 402f back to its original position to wait for the next loading.

[0040] In this embodiment, the bottom end of the inclined track 306 is fixed to the top end of the workbench 100 through a support rod 306a.

[0041] Working principle: put a large number of conductive nozzles into the vibrating disk hopper 202, the base 201 vibrates to drive the vibrating disk hopper 202 to feed, the conductive nozzles are transported along the feeding track 202a to the opening 202b and enter the material selection plate 301, because the small diameter end of the conductive nozzle needs to be processed into threads by external processing equipment, the small diameter end of the conductive nozzle needs to be transported forward, when the small diameter end of the conductive nozzle enters the material selection plate 301 forward, the conductive nozzle directly falls into the arc-shaped material guide plate 304 from the material selection opening 302, when the small diameter end of the conductive nozzle enters the material selection plate 301 backward, because the width of the front opening 302a is smaller than the diameter of the large diameter end of the conductive nozzle, the large diameter end of the conductive nozzle is stuck at the junction of the front opening 302a and the middle opening 302b, and the small diameter of the conductive nozzle The end of the conductive nozzle is turned downward from the rear opening 302c to the small diameter end, and the entire conductive nozzle falls on the arc guide plate 304. The conductive nozzle passes through the feeding track 305 and the inclined track 306 in sequence along the arc guide plate 304, and finally enters the feed trough 401f through the through hole 401e-1 on the side wall of the feed block 401e to queue up. The conductive nozzle in the feed trough 401f falls into the second feed hole 401d-1 on the long strip push block 401d under the guidance of the arc guide plate 401f-2. After the rotating motor 403f is turned on, the rotating motor 403f drives the first gear 403f-1 to rotate, and the first gear 403f-1 drives the second gear 403b-1 at the end of the rotating shaft 403b to rotate through the chain 403f-2, and then To drive the rotation of the rotating shaft 403b, the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e can be roller-type mechanical air valves of model MOV-02 of Yijia Pneumatic. When the roller on the roller-type mechanical air valve is squeezed, the roller-type mechanical air valve opens, and when the roller is not squeezed, the roller-type mechanical air valve closes. Since the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 are in opposite directions, when the rotating shaft 403b rotates, the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 rotate with the rotation of the rotating shaft 403b and touch the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e alternately to open, The first cylinder 401c and the second cylinder 402d supply air, so that the telescopic rods of the first cylinder 401c and the second cylinder 402d extend in sequence, and when the outer curved surface of the first cam 403d-1 and the outer curved surface of the second cam 403e-1 successively separate from the rollers of the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e, the first roller-type mechanical air valve 403d and the second roller-type mechanical air valve 403e are closed successively, so that the first cylinder 401c and the second cylinder 402d are cut off from air. When the outer curved surface of the first cam 403d-1 touches and opens the first roller-type mechanical air valve 403d, the gas in the gas tank enters the first cylinder 401c, and the telescopic rod of the first cylinder 401c pushes the long strip push block 401d.Until the second feed hole 401d-1 on the long strip push block 401d is aligned with the first feed hole 402f-2 at the top of the feed box 402f, so that the conductive nozzle in the second feed hole 401d-1 enters the feed hole 402f-1 of the feed box 402f through the first feed hole 402f-2 and waits to be pushed. As the rotating shaft 403b rotates, the outer curved surface of the first cam 403d-1 disengages from touching the first roller-type mechanical air valve 403d. At this time, the first roller-type mechanical air valve 403d is closed, the first cylinder 401c is de-energized, and the first cylinder 401c and The second cylinder 402d is a spring-type cylinder of the brand name Kecheng Pneumatic, model number MSA16X10SCA. After the first cylinder 401c is de-energized, the telescopic rod automatically shrinks back to its original position under the action of the internal spring. At this time, the outer curved surface of the second cam 403e-1 begins to touch and open the second roller-type mechanical air valve 403e, and the gas in the gas tank enters the second cylinder 402d. When the telescopic rod of the second cylinder 402d is extended, the spring 402f-6 is located between the feeding box 402f and the second baffle 402f-5.
