[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] Reference Figures 1 to 4The present embodiment is a rapid feeding device for electrode caps, comprising a working plate 100, a pushing assembly 200 and a feeding assembly 300. An operating hole 101 is provided in the middle of the working plate 100. A clamping strip 102 is horizontally provided on the end face of the working plate 100 at one side of the operating hole 101. The pushing assembly 200 comprises an L-shaped bracket 201 provided on the side wall of the working plate 100. A first cylinder 202 is provided on the L-shaped bracket 201. A long push-pull block 203 is fixed to the end of the telescopic rod of the first cylinder 202. The push-pull block 203 has a clamping groove 203a provided on the side wall of the working plate 100. The clamping strip 102 is slidably clamped in the clamping groove 203a. The push-pull block 20 A storage block 204 is provided at the other end. A straight plate 205 is hingedly connected to the lower portion of the side wall of the storage block 204. A storage slot S is formed between the side wall of the straight plate 205, the top wall of the storage block 204, and the side wall of the push-pull block 203. A support plate 206 is provided at the bottom end of the storage block 204. A second cylinder 207 is provided at the top end of the support plate 206. The telescopic rod of the second cylinder 207 faces the middle of the storage slot S. The feeding assembly 300 includes an arcuate guide rail 301 and an inclined guide rail 302. The cross-sections of the arcuate guide rail 301 and the inclined guide rail 302 are both concave. One end of the arcuate guide rail 301 is gap-fitted with the top end of the push-pull block 203, and the other end of the arcuate guide rail 301 is smoothly connected to the inclined guide rail 302.

[0018] Since the clamping strip 102 is slidably engaged in the clamping groove 203a, the first cylinder 202 on the L-shaped bracket 201 can push the push-pull block 203 to move toward the working hole 101 through the telescopic rod. When the push-pull block 203 moves toward the working hole 101, the top of the push-pull block 203 can just block the electrode cap in the arc guide rail 301. When the storage slot S formed between the side wall of the straight plate 205, the top wall of the storage block 204, and the side wall of the push-pull block 203 moves to one side of the working hole 101, the second cylinder 207 at the top of the support plate 206 telescopic rod pushes the electrode cap in the storage slot S into the external clamping member (the clamping member is a common prior art, as shown in the accompanying drawings). As shown, since the electrode cap only needs to have its head ground, the clamping member only clamps the tail of the electrode cap, and the head of the electrode cap is still in the storage slot S. When the telescopic rod of the first cylinder 202 contracts and pulls the push-pull block 203 away from the working hole 101, the head of the electrode cap squeezes the straight plate 205. Since the straight plate 205 is hinged to the lower part of the side wall of the storage block 204, the straight plate 205 is squeezed by the electrode cap and starts to rotate until the electrode cap passes through the straight plate 205. The first cylinder 202 pulls the push-pull block 203 to the discharge end of the storage slot S facing the arc guide rail 301. At this time, the electrode cap in the arc guide rail 301 falls into the storage slot S and waits for the next feeding.

[0019] In this embodiment, a first connecting rod 203b is provided on one side of the push-pull block 203, and a second connecting rod 205a is provided on one side of the straight plate 205. The top height of the first connecting rod 203b is lower than the top height of the second connecting rod 205a, and a spring 208 is connected between the first connecting rod 203b and the second connecting rod 205a.

[0020] The straight plate 205 is squeezed by the electrode cap and starts to rotate. After the electrode cap passes the inner wall of the straight plate 205 , the straight plate 205 can rotate back to its original position under the pulling force of the spring 208 .

[0021] In this embodiment, a first limit frame 303 and a second limit frame 304 parallel to each other are provided on both sides of the middle part of the arc guide rail 301, and an arc plate 301a is movably provided at the top of the arc guide rail 301. The arc of the arc plate 301a is the same as that of the arc guide rail 301, and a first threaded rod 301b and a second threaded rod 301c are respectively provided at positions corresponding to the first limit frame 303 and the second limit frame 304 on one side of the arc plate 301a. The first threaded rod 301b and the second threaded rod 301c respectively pass through the first limit frame 303 and the second limit frame 304 and are threadedly connected to nuts.

[0022] Since electrode caps have various specifications and different diameters, the distance between the arc plate 301a and the arc guide rail 301 can be adjusted to adapt to electrode caps of different diameters. After the position of the arc plate 301a is determined, the nut is tightened to fix the position between the arc plate 301a and the arc guide rail 301.

[0023] In this embodiment, a third limit frame 305 and a fourth limit frame 306 parallel to each other are provided on both sides of the side wall of the inclined guide rail 302, and a limit plate 302a is movably provided at the top of the inclined guide rail 302. A third threaded rod 302b and a fourth threaded rod 302c are respectively provided at positions on the side wall of the limit plate 302a corresponding to the third limit frame 305 and the fourth limit frame 306. The third threaded rod 302b and the fourth threaded rod 302c respectively pass through the third limit frame 305 and the fourth limit frame 306 and are threadedly connected with nuts.

[0024] For electrode caps with different diameters, the distance between the limiting plate 302a and the inclined guide rail 302 can be adjusted, and the nut can be tightened to fix the position between the limiting plate 302a and the inclined guide rail 302.

[0025] In this embodiment, the side walls of the arc guide rail 301 and the inclined guide rail 302 are respectively fixed to the working plate 100 through connecting blocks 307 .

[0026] Working principle: Since the specifications of the electrode caps are various and the diameters are not consistent, the distance between the arc plate 301a and the arc guide rail 301, as well as the distance between the limit plate 302a and the inclined guide rail 302, can be adjusted to adapt to the electrode caps of different diameters, ensuring that the electrode caps can be lined up and fed in the arc guide rail 301 and the inclined guide rail 302. Tighten the nut so that the first threaded rod 301b, the second threaded rod 301c, the third threaded rod 302b and the fourth threaded rod 302c are separated. The first limiting frame 303, the second limiting frame 304, the third limiting frame 305 and the fourth limiting frame 306 are fixed respectively, and can have a high adaptability to electrode caps of different specifications. Since the snap-in strip 102 is slidably snapped into the snap-in groove 203a, the first cylinder 202 on the L-shaped bracket 201 can push the push-pull block 203 to move toward the working hole 101 through the telescopic rod. When the push-pull block 203 moves toward the working hole 101, the top of the push-pull block 203 can just block the electrode cap in the arc guide rail 301. When the storage slot S formed between the side wall of the plate 205, the top wall of the storage block 204, and the side wall of the push-pull block 203 moves to one side of the working hole 101, the telescopic rod of the second cylinder 207 at the top of the support plate 206 pushes the electrode cap in the storage slot S into the external clamping member (the clamping member is a common existing technology, as shown in the accompanying drawings). Since the electrode cap only needs to be ground at the head, the clamping member only clamps the tail of the electrode cap, and the head of the electrode cap is still in the storage slot S. When the telescopic rod of the first cylinder 202 is retracted, the push-pull block is pulled. When 203 moves away from the working hole 101, the head of the electrode cap presses the straight plate 205. Since the straight plate 205 is hinged to the lower part of the side wall of the storage block 204, the straight plate 205 is squeezed by the electrode cap and starts to rotate. After the electrode cap passes the inner wall of the straight plate 205, the straight plate 205 can rotate back to its original position under the tension of the spring 208. The first cylinder 202 pulls the push-pull block 203 to the discharge end of the storage slot S facing the arc guide rail 301. At this time, the electrode cap in the arc guide rail 301 falls into the storage slot S and waits for the next feeding.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
