Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can be mechanical or electrical connections. They can be direct connections or indirect connections through an intermediate medium, and can represent the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention based on the specific circumstances.

[0028] like Figures 1 to 7As shown, this utility model embodiment provides a cylindrical spot welding device, including a conveying channel 110, a carrying mechanism 200, a spot welding mechanism 300, a positioning mechanism 400, a connecting rod 100, and a positioning wheel 500. The conveying channel 110, the carrying mechanism 200, the spot welding mechanism 300, the positioning mechanism 400, and the positioning wheel 500 are all installed on the casing 600.

[0029] The conveying channel 110 is provided with a clamping plate 120 arranged along its axial direction. The clamping plate 120 has a slot 121 arranged along its length direction on both sides. One slot 121 is higher than the other slot 121, and the two slots 121 are arranged vertically. The conveying channel 110 has a feed inlet 111 and a discharge outlet 112. The cylinder is placed in the conveying channel 110 from the feed inlet 111, and its two ends extend into the corresponding slots 121 respectively. It should be noted that the two ends of the cylinder are vertically crossed after being wound and formed, and form the same spacing as the two slots 121.

[0030] The positioning mechanism 400 is located outside the discharge port 112. The positioning mechanism 400 has an open state and a closed state. The conveying mechanism 200 is configured to perform the action of pushing the cylinder from the feed port 111 to the discharge port 112 to abut against the positioning mechanism 400 when the positioning mechanism 400 is in the closed state, so as to position the cylinder and ensure the accuracy of subsequent welding. When the positioning mechanism 400 switches from the closed state to the open state, it pushes the cylinder through the discharge port 112 so that the spot welding mechanism 300 can weld the two ends of the cylinder at multiple points.

[0031] The spot welding mechanism 300 is located outside the discharge port 112 and is used to weld the two ends of the cylinder. Specifically, during operation, the operator pushes the wound cylinder into the conveying channel 110 from the feed port 111, and inserts both ends of the cylinder into the corresponding slots 121. The transport mechanism 200 then pushes the cylinder to the discharge port 112, where a portion of it protrudes and abuts against the closed positioning mechanism 400 for positioning. The positioning mechanism 400 then switches to the open state, and the spot welding mechanism 300 performs the first spot welding on both ends of the cylinder. The transport mechanism 200 pushes the cylinder so that the spot welding mechanism 300 performs multi-point spot welding on both ends of the cylinder to fix them in place. This method has the advantages of high automation and high precision, ensuring a high yield rate and significantly reducing production costs.

[0032] In one embodiment, multiple connecting rods 100 extend along the conveying direction of the cylinder and are spaced apart axially around the cylinder to form a conveying channel 110. The multiple connecting rods 100 arranged axially around the cylinder form a robust "cage" guide structure. This effectively prevents the cylinder from jumping or tilting due to external forces or vibrations during conveying, ensuring a more straight and stable movement trajectory. The channel formed by the connecting rods 100 is open or semi-open, facilitating observation of the cylinder's conveying status and making it easier to handle potential jamming issues.

[0033] Optionally, the positioning mechanism 400 includes a fixed base 410, a connecting piece 420, a first driving device 430, and a positioning arm 440. The first driving device 430 is mounted on the fixed base 410. Both ends of the connecting piece 420 are rotatably connected to the positioning arm 440 and the fixed base 410, respectively. Specifically, the connecting piece 420 is rotatably connected to both ends of the positioning arm 440. The upper end of the positioning arm 440 is rotatably connected to the output end of the first driving device 430. The first driving device 430 can push the positioning arm 440 to rotate downwards. The downward rotation angle of the positioning arm 440 is preferably 90 degrees. At this time, the positioning arm 440 is in a vertical state so that the other end of the positioning arm 440 can abut against the end of the cylinder extending out of the discharge port 112 to achieve positioning. Specifically, the first driving device 430 is preferably a cylinder. The cylinder rod of the cylinder is rotatably connected to the upper end of the positioning arm 440. The cylinder pushes the positioning arm 440 to rotate upward or downward. It should be noted that when the positioning mechanism 400 is in the open state, the positioning arm 440 rotates upward to a position higher than the cylinder so that the cylinder can flow out from the discharge port 112.

[0034] In one embodiment, to enable the conveying mechanism 200 to push the cylinder toward the discharge port 112, the conveying mechanism 200 specifically includes a second driving device 210, a mounting base 220, and a first pushing arm 230. The mounting base 220 is located above the clamping plate 120. The first pushing arm 230 is vertically and rotatably mounted on the end of the mounting base 220 near the inlet 111, extending into the conveying channel 110. A first limiting wall 221 is provided on the mounting base 220, and the first limiting wall 221 is located near the first pushing arm 230. On the side near the feed inlet 111, it should be noted that a first mounting groove is provided on the side of the mounting base 220. The upper end of the first push arm 230 is rotatably connected to the first mounting groove. The first limiting wall 221 is the inner wall of the first mounting groove near the feed inlet 111. The first limiting wall 221 is used to restrict the first push arm 230 from swinging towards the feed inlet 111. The second driving device 210 can drive the mounting base 220 to move along the conveying direction of the cylinder, thereby driving the first push arm 230 to push the cylinder to the positioning mechanism 400 for positioning, ensuring the accuracy of subsequent welding.

[0035] The first push arm 230 can swing toward the discharge port 112. The purpose of this design is to ensure that the cylinder can push the first push arm 230 into the conveying channel 110 when feeding. When the cylinder is pushed into the conveying channel 110, its end near the feed port 111 abuts against the first push arm 230.

[0036] In one embodiment, the conveying mechanism 200 further includes a second push arm 240, wherein the second push arm 240 is vertically and rotatably disposed at one end of the mounting base 220 near the discharge port 112, the second push arm 240 extends into the conveying channel 110, the distance between the second push arm 240 and the first push arm 230 is greater than the length of the cylinder, and a second limiting wall 222 is provided on the mounting base 220, the second limiting wall 222 is located on the side of the second push arm 240 near the feed port 111, the second limiting wall 222 is used to restrict the second push arm 240 from swinging toward the feed port 111. After the first push arm 230 pushes the cylinder to the discharge port 112, the second drive device 210 drives the mounting base 220 to move towards the inlet 111, so that the second push arm 240 abuts against the end of the cylinder near the inlet 111. Furthermore, the second drive device 210 drives the mounting base 220 to drive the second push arm 240 to push the cylinder out of the discharge port 112, so that the spot welding mechanism 300 performs multi-point spot welding on both ends of the cylinder. The second push arm 240 can swing toward the discharge port 112. The mounting base 220 has a second mounting groove at the end away from the feed port 111. The second limiting arm is the inner wall of the second mounting groove. The upper end of the second push arm 240 is rotatably connected to the second mounting groove. When the mounting base 220 drives the second push arm 240 to move toward the feed port 111, the cylinder will push the second push arm 240 to swing toward the discharge port 112, so that the second push arm 240 can move to the end of the cylinder close to the discharge port 112.

[0037] In some specific embodiments, the second driving device 210 includes a motor 211, a lead screw 212, and a connecting seat 214. The lead screw 212 is rotatably mounted above the mounting base 220. Specifically, bearing seats are rotatably mounted at both ends of the lead screw 212, and the bearing seats are fixed to the housing 600. Furthermore, a nut 213 is fitted onto the lead screw 212. The connecting seat 214 is connected to the mounting base 220 and the nut 213. The motor 211 is drively connected to one end of the lead screw 212. That is, the motor 211 rotates the lead screw 212, driving the connecting seat 214 to move, thereby driving the mounting base 220 to move. It should be noted that a guide assembly is also installed. The guide assembly includes a guide rail and a slider. The guide rail extends along the conveying direction of the cylinder and is mounted on the housing 600. The slider slides on the guide rail and is fixedly connected to the connecting seat 214 to ensure the stability of the movement of the mounting base 220.

[0038] In one embodiment, the spot welding mechanism 300 includes a third driving device 310 and a first electrode arm 320 and a second electrode arm 330 arranged vertically at intervals. The first electrode arm 320 is located at the lower end of the clamping plate 120, with its end away from the feed inlet 111 protruding through the discharge outlet 112. A first electrode 321 is vertically mounted on the exposed end of the first electrode arm 320, with its upper end flush with the bottom wall of the lower jaw 121. A second electrode 331 corresponding to the first electrode 321 is mounted on the second electrode arm 330. The third driving device 310 drives the second electrode arm 330 downwards. Specifically, the third driving device 310 is a cylinder, and the second electrode arm 330 is fixedly connected to the cylinder rod. That is, the cylinder pushes the first electrode 321 to overlap the two ends of the cylinder onto the second electrode 331 for welding.

[0039] In one embodiment, the positioning wheels 500 are spaced axially around the cylinder to form a space that fits the cylinder, and the positioning wheels 500 are in rolling connection with the cylinder. The fitting space formed by the positioning wheels 500 provides additional radial support to the cylinder to ensure the stability of the spot welding.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
