Description

Technical Field

[0001] This application relates to the field of welding material storage and dispensing technology, and in particular to a welding electrode dispensing device and method. Background Technology

[0002] Welding is a material processing method that uses heat, pressure, or both to achieve interatomic bonding in the workpiece. Currently, welding technology is widely used in many industrial fields, including shipbuilding, vehicle manufacturing, power plant equipment, petrochemicals, aerospace, machinery manufacturing, and electronic components.

[0003] Welding electrodes are metal strips used as filler metal or also possessing conductive properties. Aluminum welding electrodes are mainly classified into two categories: solid electrodes and flux-cored electrodes. In conventional welding operations, when welding aluminum and aluminum alloys, thin sheet metal strips with a chemical composition similar to the base metal are typically used as filler electrodes.

[0004] In welding construction management, the quality of welding material storage and the management of its receipt and issuance directly affect the stability of welding processes and project quality. Welding electrodes, in particular, require specific temperature storage to prevent moisture absorption and deterioration, and accurate counting is necessary during issuance to achieve material traceability and cost control. Currently, welding material management relies heavily on manual labor. Based on the differentiated needs of customers, pre-processed welding electrodes are cut to specific lengths, and then managers manually store the cut electrodes in insulation equipment, record the information, and manually count and register them during issuance. This model is the foundation for the standardized use of welding materials and a necessary step in welding construction.

[0005] In existing technical solutions, the counting of welding electrodes during the packaging process is mostly done manually, with operators manually bundling and assembling a specified number of electrodes. Manual counting is prone to omissions and errors due to fatigue, and manual recording of usage information is subject to delays and tampering risks, which is not conducive to traceability and digital management. Therefore, technical improvements are urgently needed. Summary of the Invention

[0006] To facilitate the counting and discharging of welding electrodes and improve production efficiency, this application provides a welding electrode discharging device.

[0007] Firstly, the electrode feeding device provided in this application adopts the following technical solution: A welding electrode dispensing device includes a support frame, a body, a side plate, a feeding bin, a cam assembly, a roller, a traction assembly, a dispensing bin, and a counting sensor. The body is mounted on the support frame, the side plate is located on one side of the body, and the feeding bin is rotatably disposed between the body and the side plate. The feeding bin has a receiving cavity for accommodating welding electrodes. The cam assembly is mounted on the body and is used to drive the feeding bin to vibrate. The roller is rotatably mounted on the body and side plate via a servo motor and is close to the feed hopper. The roller has several limiting grooves, which are distributed in a circumferential shape. The limiting grooves are used to receive welding rods. The traction component is located between the feed hopper and the roller and is used to guide the welding rods in the receiving cavity to the limiting grooves. The discharge bin is located on the support frame and on the side of the roller away from the feed bin. The discharge bin is used to receive welding rods that fall from the roller. The counting sensor is located between the roller and the discharge bin. The detection optical path of the counting sensor is aligned with the discharge path of the limiting groove and is used to count the welding rods that fall into the discharge bin.

[0008] By adopting the above technical solution, firstly, the welder stores the welding rods in the feeding bin. The welding rods in the feeding bin are vibrated by the cam assembly and move along the traction assembly to the position of the roller. As the roller rotates continuously, when the roller rotates to the position of the limiting groove corresponding to the position of the welding rod, the welding rod will fall into the limiting groove. Each limiting groove can only hold one welding rod, and each limiting groove is used to circulate and transport the welding rods one by one.

[0009] As the drum continues to rotate, the welding rods in the limiting groove will gradually approach the discharge hopper. Under their own gravity, the welding rods will detach from the limiting groove and fall into the discharge hopper, which is used to centrally collect and store the welding rods. During the welding rod feeding process, the counting sensor counts the number of welding rods in the limiting groove, thus jointly building the basic functional framework for welding rod storage, transportation, counting and receiving.

[0010] The counting sensor is a through-beam photoelectric sensor. Its detection optical path is directly aligned with the material discharge path of the limiting slot, ensuring that each welding electrode discharged from the limiting slot accurately blocks the light path, triggering the counting signal and preventing missed or incorrect counts. This allows for accurate counting of the number of welding electrodes issued, providing reliable data support for the digital management of welding materials. The counting data is synchronized to the controller in real time, enabling digital recording of welding material issuance information for easy traceability and statistical analysis.

[0011] Preferably, it further includes a base plate, a connecting shaft, and lugs. The base plate is connected to the bottom of the feed hopper, and lugs are connected to the bottom of the base plate. The connecting shaft is horizontally arranged and rotatably connected to the main body. The axis of rotation of the connecting shaft is parallel to the axis of rotation of the roller, and the connecting shaft is close to the roller. The base plate is rotatably mounted on the connecting shaft via the lugs. The cam assembly is located on the side of the base plate away from the connecting shaft and is used to drive the base plate to rotate. The traction assembly includes guide bars and a fixing plate. The fixing plate is disposed on the support frame. The two ends of the guide bars are respectively connected to the base plate and the fixing plate. There are multiple guide bars, and each guide bar is used to guide the welding rod on the base plate to the roller.

[0012] By adopting the above technical solution, the main body and side plates constitute the supporting base of the equipment. The feeding hopper is rotatably connected to the supporting base through the bottom plate. The connecting shaft and the lugs cooperate to provide a rotation fulcrum for the bottom plate, which facilitates the cam assembly to drive the bottom plate to rotate stably, thereby realizing the vibration discharge of the feeding hopper. Under the action of vibration, the welding rods on the bottom plate will fall onto the guide strips, and then fall into the limiting groove of the roller, realizing the conveying of welding rods one by one.

[0013] Preferably, the cam assembly includes a camshaft, a cam body, a push rod, and a roller. The camshaft is rotatably connected to the body via a motor and is located below the base plate. The rotation axis of the camshaft is parallel to the rotation axis of the connecting shaft. The cam body is mounted on the camshaft. One end of the push rod is connected to the bottom surface of the base plate, and the other end is rotatably mounted on the roller via a pin. The outer peripheral surface of the roller is in contact with the outer peripheral surface of the cam body.

[0014] By adopting the above technical solution, the rotation of the camshaft can be driven by a servo motor. When the camshaft drives the cam body to rotate, the cam body pushes the push rod to move up and down through the contact transmission with the roller, thereby driving the base plate to swing up and down around the connecting shaft, realizing the vibration of the feed bin, avoiding the welding rod from getting stuck in the feed bin, and ensuring a stable supply of welding rod to the position of the roller.

[0015] Preferably, it also includes a rotating shaft and a feeding plate. The rotating shaft is rotatably connected to the body and the side plate. The rotating shaft and the rotating shaft are parallel. The roller is coaxially disposed on the rotating shaft. The limiting groove is fishhook shaped. The feeding plate is located between the roller and the discharge bin, and is tangent to the roller. The feeding plate has a feeding port for the welding rod to pass through and fall into the discharge bin.

[0016] By adopting the above technical solution, the rotation of the rotating shaft can be driven by a servo motor. The rotating shaft provides rotational driving force support for the drum. The fishhook-shaped limiting groove can limit the welding rod and prevent the welding rod from falling off during the rotation of the drum. The evenly spaced distribution of the limiting groove can realize the orderly delivery of welding rods one by one, which ensures the accuracy of the subsequent counting process.

[0017] Preferably, it further includes a first bracket, a second bracket, and a hinge block. The first bracket and the second bracket are both mounted on the support frame. The hinge block is located at one end of the discharge bin and is rotatably connected to the first bracket via a pin. The second bracket has an arc-shaped groove, and the other end of the discharge bin overlaps the arc-shaped groove. A U-shaped handle is connected to the discharge bin, and the inlet of the discharge bin faces the outlet.

[0018] By adopting the above technical solution, one end of the discharge bin is rotatably connected to the first support via a pin. Combined with a U-shaped handle, this allows the operator to easily rotate the discharge bin and pour out the welding rods held inside. The layout of the discharge bin's inlet directly facing the discharge plate's outlet ensures that the welding rods conveyed by the roller conveyor can accurately fall into the discharge bin.

[0019] Preferably, a first cover plate is hinged to the upper end of the feeding plate, and a first handle is connected to the first cover plate. The first cover plate, the main body, and the side plate together provide insulation and protection for the roller.

[0020] By adopting the above technical solution, the first cover plate, the main body, and the side plate together shield and insulate the roller, forming a relatively sealed space, reducing heat transfer between the roller and the outside air, and reducing the loss of temperature of the welding rod on the roller.

[0021] Preferably, the top of the feeding hopper is hinged with a second cover plate, and the second cover plate is provided with a second handle; the feeding hopper is provided with a heat insulation layer around its perimeter, and heating plates are embedded inside the bottom plate, the first cover plate and the second cover plate.

[0022] By adopting the above technical solution, workers can grasp the second handle and rotate the second cover plate to open the feeding hopper, facilitating the storage of welding rods inside. The heating plate heats the welding rods inside the feeding hopper from both the top and bottom sides. Combined with the insulation layer around the feeding hopper, it effectively blocks heat exchange between the inside and outside, maintaining a constant temperature environment of 70-150℃ inside the feeding hopper and ensuring the quality of stored welding rods.

[0023] The insulation layer and heating plate around the feeding hopper are combined to maintain a constant temperature environment, ensuring that the temperature inside the feeding hopper is kept within the required range and supporting continuous insulation to prevent the welding rod performance from deteriorating due to temperature fluctuations, thus preparing for subsequent distribution.

[0024] Preferably, the roller includes a pair of discs and a connecting plate. The two discs are arranged opposite to each other, and the two ends of the connecting plate are respectively connected to the two discs. Notches are provided at the edges of the two discs for receiving welding rods. The connecting plate is used to receive welding rods. A mounting block is detachably connected to the side of the disc away from the connecting plate. The mounting block is locked to the disc by fastening bolts. A limiting groove is formed on the mounting block, and the limiting groove communicates with the notch. The connecting plate, the notch, and the mounting block are all distributed at intervals along the circumference of the disc.

[0025] By adopting the above technical solution, during the production process, there will be situations where welding rods of different diameters need to be counted and discharged. In this case, mounting blocks with different sized limiting grooves can be replaced according to the specifications of the welding rods. During replacement, first loosen the fastening bolts securing the mounting block, then remove the mounting block from the disc, and finally replace it with a mounting block with the corresponding sized limiting groove for fixation. The welding wire can fall onto the plane of the two mounting blocks and the connecting plate, achieving conveying.

[0026] Preferably, the roller includes a pair of discs and a connecting plate. The two discs are arranged opposite to each other, and the two ends of the connecting plate are respectively connected to the two discs. Notches are provided at the edges of both discs for receiving welding rods. The connecting plate is used to receive welding rods. A mounting block is detachably connected to the side of the disc away from the connecting plate. A limiting groove is formed on the mounting block, and the limiting groove communicates with the notch. The connecting plate, notch, and mounting block are all distributed at intervals along the circumference of the disc. The mounting block is connected to a pin, and the disc has a slot for the pin to be inserted into; the pin has a mounting groove, and a locking block and a compression spring are provided in the mounting groove; the locking block is slidably connected in the mounting groove and is used to engage with a pre-set locking groove on the disc; the compression spring is horizontally arranged, and its two ends are respectively connected to the pin and the locking block; when the compression spring is in its natural state, part of the locking block is located outside the mounting groove, and the other part is located inside the mounting groove; An extension plate is connected to the locking block. The extension plate moves horizontally via a drive assembly, which includes a pressure rod, a tension spring, and a pull rope. One end of the pressure rod is rotatably connected to the insertion post, and the other end abuts against the connection between the extension plate and the locking block. The two ends of the tension spring are respectively connected to the insertion post and the pressure rod. One end of the pull rope is connected to the pressure rod, and the other end extends out of the insertion post. Two insertion posts are arranged in parallel, and each insertion post is equipped with a locking block.

[0027] Using the above technical solution, replacing the mounting block requires rotating the fastening bolts twice using external tools, which is somewhat cumbersome. Besides using fastening bolts to secure the mounting block, other mechanical structures can also be used for fixation.

[0028] Specifically, during installation, the operator simultaneously pinches two locking blocks with both thumbs, compressing the springs. The two locking blocks then enter the mounting slots of the two inserts, which are then gradually inserted into the slots of the disc. Once the inserts are in place, the locking blocks and the pre-set slots on the disc align. The elastic potential energy of the springs controls the locking blocks to reset and engage within the slots, preventing the inserts from detaching and enabling rapid installation of the mounting blocks.

[0029] During disassembly, the worker can hold the mounting block with one hand to better apply force to the pull rope. Then, the other hand applies a pulling force to the pull rope, in the opposite direction to the insertion direction of the plug. The tension in the pull rope causes the pressure rod to rotate, and the rotation of the pressure rod generates a horizontal component force on the extension plate. Since the locking block can only move in a straight line, the extension plate and the locking block move synchronously, compressing the spring. This causes the locking block to slowly enter and disengage from the mounting slot, allowing the plug to be removed from the disc. The entire process requires no external tools, improving convenience.

[0030] Secondly, this application also provides a method for discharging welding electrodes, which uses a discharging device with all the above-described structures to count and discharge welding electrodes, including the following steps: S1. First, the welder stores the welding rod in the feed hopper. The welding rod in the feed hopper is vibrated by the cam assembly and moves along the traction assembly to the position of the roller. As the roller rotates continuously, when the roller rotates to the position of the limiting groove corresponding to the position of the welding rod, the welding rod will fall into the limiting groove. Each limiting groove can only hold one welding rod. Each limiting groove is used to circulate and transport the welding rod one by one. S2. As the drum continues to rotate, the limiting groove carrying the welding rod will gradually approach the discharge hopper. Under its own gravity, the welding rod will leave the limiting groove and fall into the discharge hopper, which is used to centrally collect and store the welding rod. During the welding rod feeding process, the counting sensor counts the number of welding rods in the limiting groove.

[0031] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a feeding bin, cam assembly, roller, traction assembly, discharge bin and counting sensor, the welding rod in the feeding bin is vibrated by the cam assembly and moves along the traction assembly to the position of the roller, and then the welding rod falls into the limiting groove; as the roller continues to rotate, the welding rod in the limiting groove gradually approaches the discharge bin and completes the feeding. The counting sensor counts the number of welding rods in the limiting groove, realizes the digital recording of welding material distribution information, and facilitates subsequent traceability.

[0032] (2) By setting up insulation plates and heating plates, the insulation layer around the feeding hopper and the heating plate work together to maintain a constant temperature environment, ensure that the temperature inside the feeding hopper is maintained within the required range, and support continuous insulation to avoid the performance degradation of welding rods due to temperature fluctuations, thus preparing for subsequent distribution.

[0033] (3) By setting the mounting block to be detachably connected to the disc, it is convenient to replace the mounting block according to the specifications of different welding rods, thereby improving production flexibility. Attached Figure Description

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0041] Example 1 This application discloses a welding electrode feeding device. (Refer to...) Figures 1 to 3 The discharge device includes a support frame 1, a main body 2, a side plate 3, a feed bin 4, a cam assembly 5, a roller 6, a traction assembly 7, a discharge bin 8, and a counting sensor 9. The support frame 1 is fixedly installed on the ground, the main body 2 is fixedly installed on the support frame 1, and the side plate 3 is fixedly connected to one side of the main body 2. The feed bin 4 is rotatably connected between the main body 2 and the side plate 3. The feed bin 4 has a receiving cavity for storing welding rods. A bottom plate 10 is fixedly connected to the bottom of the feed bin 4, and a lug 11 is connected to the bottom of the bottom plate 10. A connecting shaft 12 is rotatably connected to the main body 2. The connecting shaft 12 is horizontally positioned below the bottom plate 10, and the bottom plate 10 is rotatably mounted on the connecting shaft 12 via the lug 11. The cam assembly 5 is installed on the main body 2 and located on the side of the bottom plate 10 away from the connecting shaft 12. The cam assembly 5 drives the bottom plate 10 to rotate around the connecting shaft 12, thereby causing the feed bin 4 to vibrate. The main body 2 and the side plate 3 constitute the supporting base of the equipment. The feeding bin 4 is rotatably connected to the supporting base through the bottom plate 10. The connecting shaft 12 and the lug 11 cooperate to provide a rotation fulcrum for the bottom plate 10, so that the cam assembly 5 can drive the bottom plate 10 to rotate stably and realize the vibration discharge of the feeding bin 4.

[0042] The cam assembly 5 includes a camshaft 51, a cam body 52, a push rod 53, and a roller 54. The camshaft 51 is rotatably connected to the body 2 via a servo motor or a rotary motor and is located below the base plate 10. The rotation axis of the camshaft 51 is parallel to the rotation axis of the connecting shaft 12. The cam body 52 is fixedly mounted on the camshaft 51. One end of the push rod 53 is connected to the bottom surface of the base plate 10, and the other end is rotatably mounted with the roller 54 via a pin. The outer circumferential surface of the roller 54 is in contact with the outer circumferential surface of the cam body 52. ​​When the camshaft 51 drives the cam body 52 to rotate, the cam body 52, through its contact with the roller 54, pushes the push rod 53 to move up and down, thereby causing the base plate 10 to swing back and forth around the connecting shaft 12, realizing the vibration of the feed bin 4, avoiding the welding rod from getting stuck in the feed bin 4, and ensuring a stable supply of welding rods.

[0043] Combination Figure 4 and Figure 5 The roller 6 is located near the connecting shaft 12. The roller 6 is rotatably connected to the body 2 and side plate 3 via a servo motor and is close to the feed hopper 4. The rotation axis of the roller 6 is parallel to the rotation axis of the connecting shaft 12. Several limiting grooves 13 are provided on the roller 6, arranged circumferentially. These grooves are used to receive welding rods. A traction assembly 7 is installed between the feed hopper 4 and the roller 6 to guide the welding rods in the receiving cavity to the limiting grooves 13. The traction assembly 7 includes guide bars 71 and a fixing plate 72. The fixing plate 72 is fixedly installed on the support frame 1. The two ends of the guide bars 71 are connected to the base plate 10 and the fixing plate 72, respectively. The guide bars 71 are made of metal and have deformation capabilities; when the base plate 10 rotates, the guide bars 71 can adapt by bending. Several guide bars 71 are provided and are inclined. Each guide bar 71 is used to transport the welding rods on the base plate 10 to the limiting grooves 13. The welding rods on the base plate 10 will fall onto the guide bar 71 under the action of vibration, and then fall into the limiting groove 13 of the roller 6, realizing the feeding of welding rods one by one.

[0044] The discharge bin 8 is mounted on the support frame 1 and located on the side of the roller 6 away from the feed bin 4. The discharge bin 8 is used to receive welding rods that fall from the roller 6. The counting sensor 9 is mounted on the body 2 and is located between the roller 6 and the discharge bin 8. In this embodiment, the counting sensor 9 is a through-beam photoelectric sensor. The detection optical path of the counting sensor 9 is aligned with the discharge path of the limiting groove 13, ensuring that each welding rod sent from the limiting groove 13 can accurately block the optical path and trigger the counting signal, avoiding missed or incorrect counting, thereby counting the number of welding rods issued and providing reliable data support for the digital management of welding materials.

[0045] First, the welder stores the welding rods in the feed bin 4. The welding rods in the feed bin 4 are vibrated by the cam assembly 5 and move along the traction assembly 7 to the position of the roller 6. As the roller 6 rotates continuously, when the roller 6 rotates to the position of the limiting groove 13 corresponding to the position of the welding rod, the welding rod will fall into the limiting groove 13. Each limiting groove 13 can only hold one welding rod, and each limiting groove 13 is used to circulate and transport the welding rods one by one.

[0046] As the roller 6 continues to rotate, the welding rods in the limiting groove 13 will gradually approach the discharge bin 8. Under the action of their own gravity, the welding rods will leave the limiting groove 13 and fall into the discharge bin 8, which is used to centrally collect and store the welding rods. During the welding rod feeding process, the counting sensor 9 counts the number of welding rods in the limiting groove 13, thus jointly building the basic functional framework for welding rod storage, conveying, counting and receiving.

[0047] Specifically, a rotating shaft 14 is rotatably connected between the main body 2 and the side plate 3. The axis of rotation of the rotating shaft 14 is parallel to the axis of rotation of the connecting shaft 12. The roller 6 is coaxially mounted on the rotating shaft 14. When the rotating shaft 14 rotates, it can drive the roller 6 to rotate. In this embodiment, the limiting groove 13 is fishhook-shaped. The fishhook-shaped limiting groove 13 can limit the welding rod and prevent the welding rod from falling out of the limiting groove 13 during the rotation of the roller 6. A feeding plate 15 is also installed between the roller 6 and the discharge bin 8. The feeding plate 15 is tangent to the roller 6. A feeding port 16 is opened through the feeding plate 15. The feeding port 16 is used for the welding rod in the limiting groove 13 to pass through and fall into the discharge bin 8.

[0048] The support frame 1 is further equipped with a first bracket 17 and a second bracket 18, which are located at opposite ends of the discharge bin 8. A hinge block 19 is connected to one end of the discharge bin 8, and the hinge block 19 is rotatably connected to the first bracket 17 via a pin. The pivot of the hinge block 19 is perpendicular to the length direction of the discharge bin 8. An arc-shaped groove is formed on the second bracket 18, which matches the surface contour of the discharge bin 8. The other end of the discharge bin 8 overlaps within the arc-shaped groove. The inlet of the discharge bin 8 is directly opposite the outlet 16 of the discharge plate 15. A U-shaped handle 20 is also fixedly connected to the discharge bin 8 for personnel to grip. Operators can grip the U-shaped handle 20 and rotate the discharge bin 8 to empty the welding rods held inside.

[0049] In this embodiment, a first cover plate 21 is hinged to the upper end of the feeding plate 15, and a first handle 22 is connected to the first cover plate 21. The first cover plate 21, the body 2, and the side plate 3 together shield and insulate the roller 6, forming a relatively sealed space, reducing heat transfer between the roller 6 and the outside air, and reducing the temperature loss of the welding rod on the roller 6. A second cover plate 23 is hinged to the top of the feeding bin 4, and a second handle 24 is fixedly connected to the second cover plate 23. The operator can grab the second handle 24 to rotate the second cover plate 23, thereby opening the opening of the feeding bin 4, making it convenient to store the welding rod in the feeding bin 4. Insulation layers 25 are provided around the feeding bin 4, and heating plates 26 are embedded inside the bottom plate 10, the first cover plate 21, and the second cover plate 23. The heating plate 26 can heat the welding rod inside the feeding hopper 4 from the upper and lower sides. Together with the heat insulation layer 25 around the feeding hopper 4, it effectively blocks the heat exchange between the inside and outside, so that the feeding hopper 4 maintains a constant temperature environment of 70-150℃, ensuring the quality of welding rod storage.

[0050] In addition, the roller 6 includes a disc 61 and a connecting plate 62. Two discs 61 are arranged opposite each other, and the rotating shaft 14 is fixedly connected to the center of the disc 61. The two ends of the connecting plate 62 are respectively connected to the two discs 61, and the connecting plate 62 is located between the two discs 61 and close to the edge of the disc 61. Several connecting plates 62 are provided, and each connecting plate 62 is spaced apart along the circumference of the disc 61. Notches 27 are opened at the edges of both discs 61. The notches 27 are used to accommodate welding rods, and the position of the notches 27 corresponds to the position of the end of the connecting plate 62. The connecting plate 62 is used to receive welding rods so that the welding rods can be placed on the connecting plate 62. A mounting block 28 is detachably connected to the side of the disc 61 away from the connecting plate 62. The mounting block 28 is locked to the disc 61 by fastening bolts. A fishhook-shaped limiting groove 13 is provided on the mounting block 28, and the limiting groove 13 communicates with the notch 27. After the welding rod is placed on the connecting plate 62, both ends of the welding rod are located in the notches 27 of the two discs 61 and the limiting grooves 13 of the mounting block 28, respectively.

[0051] During production, there may be situations where welding rods of different diameters need to be counted and discharged. In such cases, the mounting blocks 28 with different sizes of limiting grooves 13 can be replaced according to the specifications of the welding rods. During replacement, first loosen the fastening bolts securing the mounting block 28, then remove the mounting block 28 from the disc 61, and finally replace it with a mounting block 28 of the corresponding specification of limiting groove 13 for fixation. The welding wire can fall onto the plane containing the two mounting blocks 28 and the connecting plate 62, thus achieving conveying.

[0052] The implementation principle of the electrode dispensing device in this application embodiment is as follows: When using the automatic dispensing device to automatically count the electrodes, the second cover plate 23 hinged to the top of the feeding hopper 4 is first manually opened, and the electrodes to be dispensed are loaded into the feeding hopper 4. Then, the second cover plate 23 is closed. At this time, the heating plate 26 embedded in the base plate 10 and the second cover plate 23 is activated, and together with the heat insulation layer 25 set around the feeding hopper 4, the electrode in the feeding hopper 4 is heated and kept warm to ensure that the temperature in the feeding hopper 4 is maintained within the required range, thus preparing for subsequent dispensing.

[0053] When a welder needs to collect welding rods, after passing the equipment's identity verification process, the controller triggers the distribution process. First, the relevant drive structure of the cam assembly 5 is activated, causing the camshaft 51, which is rotatably mounted between the body 2 and the side plate 3, to start rotating. The cam body 52, mounted on the camshaft 51, rotates synchronously with the camshaft 51. Since the outer circumferential surface of the cam body 52 is in contact with the outer circumferential surface of the roller 54, which is rotatably mounted at the end of the push rod 53 via a pin, the rotation of the cam body 52 will push the push rod 53 to move up and down. One end of the push rod 53 is connected to the bottom surface of the base plate 10, and the base plate 10 is rotatably mounted on the connecting shaft 12 between the body 2 and the side plate 3 via the lug 11 connected to the bottom. Therefore, the up and down movement of the push rod 53 causes the base plate 10 and the feed bin 4 fixed on the base plate 10 to vibrate up and down around the connecting shaft 12, preventing the welding rod in the feed bin 4 from getting stuck and ensuring that the welding rod can move smoothly towards the roller 6.

[0054] Simultaneously, the rotating shaft 14, which passes between the main body 2 and the side plate 3 and is parallel to the camshaft 51, begins to rotate. The roller 6 mounted on the rotating shaft 14 rotates synchronously with the rotating shaft 14. The welding rod in the feed bin 4 moves to the roller 6 under the action of vibration and enters the hook-shaped limiting grooves 13 evenly distributed along the length of the edge of the roller 6 under the action of gravity. As the roller 6 continues to rotate, the limiting grooves 13 drive the welding rod to move in the discharge direction. When the welding rod rotates with the limiting grooves 13 to the counting sensor 9 installed on the side wall of the main body 2, since the counting sensor 9 is a through-beam photoelectric sensor and its detection light path is directly opposite the discharge path of the limiting grooves 13 on the roller 6, the welding rod will block the light of the counting sensor 9, triggering a counting signal and realizing accurate counting of each welding rod.

[0055] After the counting is completed, the welding rods continue to rotate with the roller 6, and eventually detach from the limiting groove 13 and enter the discharge bin 8 located next to the roller 6. The discharge bin 8 is rotatably connected to the first bracket 17 installed at the bottom of the main body 2 via a pin. When a certain number of welding rods are collected in the discharge bin 8 or the welder completes the retrieval operation, the welder can hold the U-shaped handle 20 fixedly installed on the outer wall of the discharge bin 8 and push the discharge bin 8 to rotate around the pin on the first bracket 17 to pour out the welding rods in the discharge bin 8, thus completing the entire automatic counting and dispensing process of welding rods.

[0056] Example 2 The difference between Embodiment 2 and Embodiment 1 lies in the method of assembling and disassembling the mounting block 28. In this embodiment, the mounting block 28 is not fastened with bolts, but rather with other mechanical structures. (Refer to...) Figure 6 and Figure 7 Specifically, a pin 29 is fixedly connected to the mounting block 28. The pin 29 has a rectangular cross-section and is perpendicular to the plane of the disc 61. The disc 61 has a slot for the pin 29 to be inserted into. A mounting groove 30 is provided on the pin 29. A locking block 31 and a compression spring 32 are provided within the mounting groove 30. The locking block 31 is slidably connected within the mounting groove 30 and moves along the width direction of the pin 29, i.e., perpendicular to the insertion direction of the pin 29. The locking block 31 is used to engage with a pre-set slot on the disc 61, which communicates with the slot. The locking block 31 can move by using a T-shaped block 33 and a T-shaped groove 34. Specifically, a T-shaped block 33 is fixedly connected to one side of the locking block 31, and a corresponding T-shaped groove 34 is provided within the mounting groove 30. The T-shaped block 33 moves linearly along the T-shaped groove 34. The compression spring 32 is horizontally positioned, with its two ends connected to the insert post 29 and the locking block 31, respectively. When the compression spring 32 is in its natural state, part of the locking block 31 is located outside the mounting groove 30, and the other part is located inside the mounting groove 30.

[0057] An extension plate 35 is fixedly connected to the locking block 31. The extension plate 35 is located within the mounting groove 30 and extends in a direction close to the mounting block 28. The extension plate 35 moves horizontally via a drive assembly 36. The drive assembly 36 includes a pressure rod 361, a tension spring 362, and a pull rope 363. One end of the pressure rod 361 is rotatably connected to the insertion post 29, and the other end abuts against the connection position between the extension plate 35 and the locking block 31. The two ends of the tension spring 362 are hinged to the insertion post 29 and the pressure rod 361, respectively. One end of the pull rope 363 is connected to the pressure rod 361, and the other end extends out of the insertion post 29. Two insertion posts 29 are provided in parallel, located at both ends of the mounting block 28. Each insertion post 29 is equipped with a locking block 31, a compression spring 32, an extension plate 35, and a drive assembly 36. It should be noted that the ends of the two pull ropes 363 located outside the insertion post 29 can be connected together so that the operator can pull the two pressure rods 361 simultaneously.

[0058] During installation, the operator simultaneously pinches the two locking blocks 31 with both thumbs, compressing the compression spring 32. The two locking blocks 31 then enter the mounting slots 30 of the two inserts 29. The inserts 29 are then gradually inserted into the slots of the disc 61. Once the inserts 29 are in place, the locking blocks 31 and the preset slots on the disc 61 correspond. The elastic potential energy of the compression spring 32 controls the locking blocks 31 to reset and engage in the slots, thus preventing the inserts 29 from detaching from the slots and enabling the rapid installation of the mounting block 28.

[0059] During disassembly, the worker can hold the mounting block 28 with one hand to better apply force to the pull rope 363. Then, the other hand applies a pulling force to the pull rope 363, in the opposite direction to the insertion direction of the insertion post 29. The pulling force of the pull rope 363 can drive the pressure rod 361 to rotate. The rotation of the pressure rod 361 will generate a horizontal component force on the extension plate 35. Since the locking block 31 can only move in a straight line, the extension plate 35 and the locking block 31 move synchronously and squeeze the compression spring 32, causing the locking block 31 to slowly enter the mounting groove 30 and then disengage from the groove, so that the insertion post 29 can be removed from the disc 61. The entire process does not require external tools, improving convenience.

[0060] Based on the above embodiments, this application also provides a method for discharging welding electrodes, which uses a discharging device with all the above structures to count and discharge welding electrodes, including the following steps: S1: First, the operator places the welding rods correctly inside the feed hopper 4. Under the vibration of the cam assembly 5, the welding rods in the feed hopper 4 are arranged in an orderly manner along the traction assembly 7 and conveyed to the workstation of the roller 6. As the roller 6 rotates at a uniform speed, when the limiting groove 13 on the surface of the roller 6 rotates to match the position of the welding rod, the welding rod will accurately fall into the limiting groove 13. Each limiting groove 13 is designed to accommodate only a single welding rod. Through the cyclical operation of multiple sets of limiting grooves 13, the welding rods are conveyed one by one in an orderly manner.

[0061] S2: As the roller 6 continues to rotate, the limiting groove 13 carrying the welding rods will gradually move to the area close to the discharge bin 8. Under its own gravity, the welding rods will detach from the limiting groove 13 and fall smoothly into the discharge bin 8, which will then serve as the centralized storage bin for the welding rods. Throughout the entire welding rod feeding process, the counting sensor 9 will perform real-time quantity counting of the welding rods conveyed by the limiting groove 13 to ensure accurate and controllable distribution of welding rods.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
