Description

Technical Field

[0001] The utility model relates to the technical field of electrode cap replacement, in particular to an electrode cap replacement machine. Background Art

[0002] The electrode cap is an essential component in the welding process. Installed at the end of the welding torch, it plays a crucial role in conducting current and providing welding pressure. In modern automated production processes, automated electrode cap replacement equipment is widely used to improve production efficiency and ensure consistent welding quality. These devices enable quick and accurate replacement of electrode caps, reducing manual intervention and improving production continuity and reliability.

[0003] Chinese invention patent CN118417670A discloses an electrode cap replacement mechanism, comprising a frame, a cap removal mechanism, and a cap installation mechanism. The cap installation mechanism comprises a cap outlet, a push assembly, an upper cover, a lower cover, a locking portion, and a magazine. Two cap outlet channels are arranged in an alternating pattern within the cap outlet, with outlet openings connected to the channels on both the first and second surfaces of the cap outlet. In this mechanism, the electrode caps within the magazine are arranged closely together. When an electrode cap needs to be replaced, the push assembly pushes the rearmost electrode cap within the magazine, pushing each electrode cap into the cap outlet channel. The electrode caps entering the cap outlet channel are then pushed along the cap outlet channel and moved to the outlet opening for installation by the subsequent electrode caps. However, in actual use, due to the excessive length of the cap outlet channel, multiple electrode caps often remain within the cap outlet channel while the machine is operating. After all the electrode caps in the magazine have been used up, some remain within the cap outlet channel, unable to be pushed further to the outlet opening and thus remaining trapped in the channel, preventing them from being effectively utilized. Therefore, there is still room for improvement. Utility Model Content

[0024] See also Figure 1 as well as Figure 2 The present invention discloses an electrode cap replacement machine, including a cap discharging frame 1, a magazine 2, a cap discharging portion 3, and a power mechanism 4. The magazine 2 is arranged in the cap discharging frame 1, and the magazine 2 is used to store the electrode cap. The cap discharging portion 3 is arranged at one end of the cap discharging frame 1. The cap discharging portion 3 is provided with a cap discharging channel 31 and a cap discharging opening 32. The cap discharging channel 31 is connected to the magazine 2. The power mechanism 4 is arranged on the cap discharging frame 1, and the power mechanism 4 is used to push the electrode cap in the magazine 2 toward the cap discharging channel 31. The power mechanism 4 is provided with a pushing member 5, and the pushing member 5 is used to push the electrode cap in the cap discharging channel 31 toward the cap discharging opening 32.

[0025] Specifically, a cap discharging frame 1 has an opening on one side, and a magazine 2 is disposed at the opening of the cap discharging frame 1. The magazine 2 is detachably connected to the opening of the cap discharging frame 1. A storage channel 21 for storing electrode caps is provided within the magazine 2. In this embodiment, two storage channels 21 are provided, arranged parallel to each other within the magazine 2. Two cap discharging openings 32 and two cap discharging channels 31 are provided, and the two cap discharging openings 32 are disposed on opposite sides of the cap discharging portion 3. One end of each cap discharging channel 31 communicates with a different storage channel 21, and the other end communicates with a different cap discharging opening 32. A power mechanism 4 is disposed at the bottom of the cap discharging frame 1. When a new electrode cap needs to be replaced, the power mechanism 4 pushes the electrode cap in the magazine 2 toward the cap outlet channel 31, so that the electrode cap moves along the storage channel 21 and the cap outlet channel 31 toward the cap outlet opening 32; when there is no electrode cap in the magazine 2 and there is an electrode cap in the cap outlet channel 31, the pushing member 5 is used to push the electrode cap in the cap outlet channel 31 toward the cap outlet opening 32, ensuring that the electrode cap in the cap outlet channel 31 can be fully utilized, avoiding the problem of the electrode cap being trapped in the cap outlet channel 31 and being unusable, and improving resource utilization.

[0026] See also Figure 2 The cap outlet channel 31 includes a first channel 33 and a second channel 34. The first channel 33 is connected to the magazine 2, and the second channel 34 is connected to the cap outlet opening 32. Both the first channel 33 and the second channel 34 can only accommodate one electrode cap. Specifically, the first channel 33 is connected to the storage channel 21 in the magazine 2. When the electrode cap in the first channel 33 is pushed into the second channel 34 by the pusher 5, the electrode cap in the second channel 34 is opposite to the cap outlet opening 32. The setting of the first channel 33 and the second channel 34 shortens the cap outlet channel 31, so that the cap outlet channel 31 can only accommodate two electrode caps at most, reducing the accumulation of electrode caps in the cap outlet channel 31. The pusher 5 only needs to push the electrode cap in the first channel 33 to the electrode cap in the second channel 34 to move all the electrode caps in the cap outlet channel 31 toward the cap outlet opening 32, ensuring that all the electrode caps in the cap outlet channel 31 can be fully utilized.

[0027] See also Figure 2 The power mechanism 4 includes a guide rail 41, a slider 42, a driving member, a connecting rod and a first pushing block 43. The guide rail 41 is arranged in the cap-out frame 1, and the guide rail 41 is arranged parallel to the magazine 2. The slider 42 is slidably connected to the guide rail 41. The driving member is used to drive the slider 42 to slide along the guide rail 41. A sliding hole for sliding the connecting rod is provided on one side of the magazine 2. The two ends of the connecting rod are respectively connected to the slider 42 and the first pushing block 43. The first pushing block 43 is arranged in the magazine 2.

[0028] Specifically, the driving member is a pneumatic cylinder, the output end of which is connected to the guide rail 41 and is used to control the movement of the slider 42 on the guide rail 41. A sliding hole for the connecting rod to slide is provided on the side of the magazine 2 near the guide rail 41. The length of the sliding hole is consistent with the length of the guide rail 41. The connecting rod passes through the sliding hole and is slidably connected to the sliding hole. The first pushing block 43 is provided in the storage channel 21. When the power mechanism 4 is in operation, the pneumatic cylinder drives the slider 42 to slide along the guide rail 41. The slider 42 moves in a direction close to the cap outlet channel 31. The slider 42 drives the connecting rod and the first pushing block 43 to move in the direction of the cap outlet channel 31. The first pushing block 43 pushes the electrode cap in the magazine 2 farthest from the cap outlet channel 31 in the direction of the cap outlet channel 31, so that all the electrode caps in the magazine 2 move along the storage rail and the cap outlet channel 31 to the cap outlet opening 32. Through the cooperation of the cylinder, the guide rail 41, the slider 42 and the connecting rod, the movement of the first push block 43 is precisely controlled, thereby accurately pushing the electrode cap in the magazine 2 toward the cap outlet channel 31, thereby improving the efficiency and accuracy of electrode cap replacement.

[0029] See also Figure 2 The pushing member 5 includes a second pushing block 52 connected to the first pushing block 43. When the first pushing block 43 moves to one end of the sliding hole close to the first channel 33, the second pushing block 52 is located in the first channel 33. The second pushing block 52 pushes the electrode cap in the first channel 33 to move toward the second channel 34, and makes the electrode cap in the second channel 34 face the cap outlet 32, ensuring that after the electrode cap in the clip 2 is used up, a special pushing component can continue to push the electrode cap in the cap outlet channel 31, solving the problem of the electrode cap in the cap outlet channel 31 being stuck and unusable. The continuous pushing of the electrode cap in the cap outlet channel 31 is achieved, the utilization rate of the electrode cap is improved, and the continuity of the replacement of the electrode cap is ensured.

[0030] See also Figure 2 The second pushing block 52 is adapted to the first channel 33, ensuring that the second pushing block 52 can smoothly push all the electrode caps in the cap outlet channel 31 to the cap outlet 32, and in the process of pushing the electrode cap, the force is more uniform, avoiding the electrode cap from rotating when turning or being blocked in the channel, resulting in mismatch with the electrode rod, further improving the efficiency and stability of electrode cap replacement.

[0031] See also Figure 2 The first push block 43 is detachably connected to the second push block 52. The push member 5 also includes a fixing rod 51, which is connected to the side of the first push block 43 near the first channel 33. A fixing groove 53 is recessed on one side of the second push block 52, which engages with the fixing rod 51. The fixing rod 51 and the fixing groove 53 cooperate to achieve a detachable connection. When the push blocks need to be replaced or repaired, the first push block 43 and the second push block 52 can be easily separated.

[0032] See also Figure 2 The side of the second pushing block 52 near the first channel 33 is made of an elastic material. In this embodiment, the side of the second pushing block 52 near the first channel 33 is made of silicone. During the pushing process of the electrode cap, the elastic material can provide a buffer for the electrode cap and the first channel.

[0033] The implementation principle of this embodiment is as follows:

[0034] When the electrode cap needs to be replaced, the cylinder drives the slider 42 to slide along the guide rail 41, and the slider 42 moves toward the direction close to the cap outlet channel 31. The slider 42 drives the connecting rod and the first push block 43 to move toward the cap outlet channel 31. The first push block 43 pushes the electrode cap farthest from the cap outlet channel 31 in the magazine 2 to move toward the cap outlet channel 31, so that the electrode cap enters the cap outlet channel 31 along the storage channel 21 and leads to the cap outlet port 32.

[0035] When the electrode cap in the magazine 2 is used up, the first pushing block 43 is continued to be driven to move toward the cap outlet channel 31, so that the first pushing block 43 moves to the end of the sliding hole close to the first channel 33, and the second pushing plate is pushed into the first channel 33. The second pushing plate pushes the electrode cap in the first channel 33 to move toward the second channel 34, and the electrode cap in the second channel 34 is opposite to the cap outlet opening 32, ensuring that the electrode cap in the cap outlet channel 31 can be fully utilized, avoiding the problem of the electrode cap being trapped and unusable in the cap outlet channel 31.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
