Description
Technical Field
[0001] This application relates to the field of welding wire counting device technology, and in particular to an automatic welding wire feeding device and method. Background Technology
[0002] Welding is a processing method that uses heat or pressure to bond parts together. Currently, welding technology is widely used in shipbuilding, vehicles, power plant equipment, petrochemicals, aerospace, machinery, and electronic devices. Welding wire is a metal wire used as filler metal or simultaneously as a conductor in welding. Aluminum welding wire can be mainly divided into solid welding wire and flux-cored welding wire. Generally, when welding aluminum and aluminum alloys, thin plates with a chemical composition similar to the base material are often cut into strips as welding wire.
[0003] Depending on the customer's specific needs, the processed welding wire needs to be cut into certain lengths, and then bundled or packaged in specific quantities. Currently, when the welding wire is cut and then discharged, the cut wires are usually collected in the same storage silo, making it impossible to weigh and count the cut wires.
[0004] In existing technologies, the counting of welding wire during packaging is usually done manually by workers, who bundle a specified number of welding wires together. This method can lead to discrepancies in the count, and it is also inefficient and physically demanding for workers, thus requiring improvement. Summary of the Invention
[0005] To facilitate the counting and feeding of welding wire and reduce the labor intensity of personnel, this application provides an automatic welding wire feeding device.
[0006] Firstly, the automatic welding wire feeding device provided in this application adopts the following technical solution: An automatic welding wire feeding device includes a frame, a feeding bin, a rotating shaft, rollers, a pressure plate, a feeding guide plate, a counting sensor, and a discharging bin. The feeding bin is mounted on the frame and has an opening forming a receiving cavity for storing welding wire. The rotating shaft is rotatably connected to the frame via a servo motor. The rollers are coaxially mounted on the rotating shaft and are close to the feeding bin. Limiting grooves are provided on the rollers for clamping single welding wires. The welding wires in the feeding bin are fed to the rollers via vibration. A plurality of limiting grooves are provided on the rollers, spaced apart along the circumferential direction. The pressure plate is located above the roller and is arc-shaped, used to press the welding wire into the limiting groove; the discharge bin is located on the side of the roller away from the feed bin, and is used to receive the welding wire falling into the limiting groove; the feeding guide plate is located on the frame and is used to push the welding wire on the limiting groove into the discharge bin; the counting sensor is located on the frame and between the feeding guide plate and the discharge bin, and is used to count the welding wire falling into the discharge bin.
[0007] By adopting the above technical solution, during production, the welder first puts a certain amount of welding wire into the feed hopper. The welding wire in the hopper is then conveyed to the position of the roller by vibration. The vibration of the feed hopper can be driven by mechanical vibration control, where a motor drives an eccentric block to rotate, generating centrifugal force that drives the feed hopper wall to vibrate. The vibration frequency can be changed by adjusting the motor speed. This vibration control is existing technology and can be directly applied to this application, so it will not be described in detail here.
[0008] Simultaneously, a servo motor drives the rotating shaft to rotate. When the roller rotates to the position corresponding to the limit groove and the welding wire, the welding wire will be stuck in the limit groove. Each limit groove corresponds to the feeding of one welding wire, realizing continuous feeding of the welding wire. The pressure plate above the roller can act as a barrier to prevent the welding wire from falling out of the limit groove during rotation.
[0009] As the rollers continue to rotate, the welding wire gradually approaches the discharge hopper and leaves the area where the pressure plate is located. At this point, the pressure plate no longer blocks the welding wire. Under the action of the feeding guide plate, the welding wire in the limiting groove is pushed into the discharge hopper. At the same time, the counting sensor counts the number of welding wires passing through this area of the discharge hopper, realizing automatic counting of welding wires, replacing manual counting, improving counting accuracy and production efficiency, and reducing the labor intensity of personnel.
[0010] Preferably, it further includes a support plate and an adjusting plate. The support plate is disposed in the feeding hopper and is used to receive the welding wire. The support plate is provided with a ramp, and the roller is located on the lower side of the ramp. The adjusting plate is disposed in the feeding hopper and is located above the support plate. A gap is left between the adjusting plate and the support plate for a single welding wire to pass through. The adjusting plate is movably mounted on the frame. The adjusting plate has a strip-shaped hole, and the fastening screw passes through the strip-shaped hole and is threaded onto the frame.
[0011] By adopting the above technical solution, the welding wire is placed on the support plate and gradually moves along the slope towards the roller under the action of vibration. The presence of the adjusting plate can control the welding wire to approach the roller in a single row, avoiding the welding wires from clustering together and making it easier for a single welding wire to be clamped onto the limiting groove.
[0012] During the production process, workers can adjust the height of the adjusting plate according to the specifications of the welding wire, change the gap between the adjusting plate and the support plate, and ensure that the welding wire is fed to the rollers in a single row.
[0013] Preferably, it also includes a baffle, one side of which is rotatably connected to the discharge hopper, and the other side of which is snapped or inserted into the frame. The baffle is used to block the welding wire falling from the discharge guide plate.
[0014] By adopting the above technical solution, the baffle can act as a barrier to protect the welding wire ejected by the cutting blade, preventing it from falling out of the discharge hopper. When material needs to be retrieved, the baffle can be rotated to overcome friction, thereby opening the discharge hopper and creating sufficient space for operators to carry out the operation.
[0015] Preferably, it also includes a first plate and a second plate, which are used to cover the opening of the feed hopper. The first plate is disposed on the frame, and the second plate is rotatably connected to the first plate. The second plate is connected to a handle for workers to grip. The opening of the feed hopper is provided with a magnetic buckle, which is magnetically attracted to the second plate.
[0016] By adopting the above technical solution, the first and second plates can block the opening of the feed hopper, preventing debris from entering the receiving cavity. When feeding is needed, the operator can grasp the handle, apply force to the second plate, and control the second plate to rotate around the first plate to place the welding wire into the receiving cavity. The presence of the magnetic clasp can improve the connection stability between the second plate and the feed hopper, while not interfering with the opening and closing of the second plate.
[0017] Preferably, the feeding guide plate includes an arc-shaped segment and a straight segment. The arc-shaped segment is located at the upper end of the roller and is arranged along the distribution direction of each of the limiting grooves. When the welding wire is stuck in the limiting groove, the welding wire is between the arc-shaped segment and the pressure plate. One end of the straight segment is connected to the arc-shaped segment, and the other end of the straight segment is inclined along the direction close to the discharge hopper. The straight segment is used to push the welding wire out of the limiting groove.
[0018] By adopting the above technical solution, when the roller drives the welding wire to rotate in the direction close to the discharge hopper, the welding wire can smoothly pass between the arc segment and the pressure plate because the curvature of the arc segment is the same as the curvature of the circle formed by each limiting groove. When the welding wire moves to the intersection of the arc segment and the straight segment, the welding wire and the straight segment move relative to each other (the straight segment is stationary, while the welding wire is rotating). At this time, the straight segment will exert a component force on the welding wire, pushing the welding wire in the limiting groove out and falling into the discharge hopper.
[0019] Preferably, it also includes a strip block, the roller has a strip groove, the strip block is engaged in the strip groove, the limiting groove is opened along the length direction of the strip block; the strip block has a recessed groove, the recessed groove and the strip groove are connected, the strip block is locked on the roller by a fastening bolt, the fastening bolt is located in the recessed groove.
[0020] By adopting the above technical solution, during the production process, there will be situations where welding wires of different diameters need to be counted and discharged. In this case, the position of the adjusting plate can be adjusted according to the specifications of the welding wire, thus changing the distance between the adjusting plate and the support plate. When adjusting the adjusting plate, first loosen the fastening screws, then control the adjusting plate to move up and down to the desired position. During the movement, the fastening screws must always remain within the slotted hole. Finally, tighten the fastening screws again to fix the position of the adjusting plate.
[0021] Similarly, different specifications of welding wire require correspondingly sized limiting grooves. In this case, first loosen the fastening bolts securing the strip block, remove the strip block from the groove, and then replace it with a strip block of the appropriate size limiting groove and secure it. The fastening bolts will be locked within the groove and will not affect the welding wire in the limiting groove.
[0022] Preferably, it further includes a strip block, the roller having a strip groove, the strip block being engaged in the strip groove; it also includes a locking block, a first compression spring, a wedge block, a push block, a second compression spring, a U-shaped frame, and a push rod, the strip block having an installation groove, two locking blocks symmetrically arranged, the two locking blocks being connected by the first compression spring, the elastic force direction of the first compression spring being set along the width direction of the strip block; when the first compression spring is in its natural state, a part of the locking block is located in the installation groove, and the other part is engaged in a preset locking groove on the roller; The wedge block is located in the mounting groove and connected to the locking block. Both locking blocks are provided with wedge blocks. The two ends of the second compression spring are respectively connected to the strip block and the U-shaped frame. The elastic force direction of the second compression spring is parallel to the length direction of the strip block. The push block is provided on the U-shaped frame and two are symmetrically arranged. The push block is slidably connected in the mounting groove. The push block is used to push the wedge surface of the wedge block. The two push blocks are used to drive the two locking blocks to move closer to each other. The push rod is connected to the U-shaped frame and is located at one end of the strip block.
[0023] Using the above technical solution, replacing the strip block requires rotating the fastening bolts twice using external tools, which is somewhat cumbersome. Besides using fastening bolts to secure the strip block, other mechanical structures can also be used for fixation.
[0024] During installation, the worker simultaneously pinches the two locking blocks with both thumbs, compressing the first compression spring. The two locking blocks move closer together and into the mounting groove, allowing the strip block to gradually engage with the groove. When the locking blocks move into the pre-set groove on the roller, the elastic force of the first compression spring causes the two locking blocks to move away from each other and engage with the roller, thus installing the strip block. At this point, the strip block can no longer move along the groove.
[0025] When it's necessary to disassemble the strip block, the worker can apply force to the push rod. The push rod drives the U-shaped frame to move linearly, causing the two push blocks to move synchronously and abut against the wedge-shaped surfaces of the two wedge blocks. This drives the two locking blocks to move linearly and move closer to each other. Once the two locking blocks disengage from the two locking slots, the strip block can be removed from the strip slot. After the force on the push rod is removed, the force of the second compression spring can reset the U-shaped frame and push blocks.
[0026] Preferably, the strip block has a groove, and the push block is slidably connected to the groove.
[0027] By adopting the above technical solution, a matching slider and groove can be set on the push block to achieve linear movement of the push block.
[0028] Preferably, it also includes a face recognition module and a high-definition touch screen, both of which are mounted on the rack and connected to each other via a terminal. The face recognition module is used to identify the welder's identity, and the high-definition touch screen is used to display material requisition information.
[0029] By adopting the above technical solution, the terminal can quickly identify the welder's identity information through a facial recognition module, match it with the welding material distribution records in the data platform, retrieve the welder's material requisition information, and display it on a high-definition touchscreen. The welder confirms the type, quantity, specifications, furnace batch number, usage direction, and project name of the recycled welding rods through a PC display interface. After confirming that everything is correct, the welder begins the material feeding and counting process, feeding the welding wire heads one by one into the equipment. The equipment performs real-time and accurate counting. After the welding wire head counting is complete, the worker enters the remaining quantity and finally clicks the data upload button to complete the entire recycling process.
[0030] Recycling information will be automatically uploaded to the data platform and automatically summarized and statistically analyzed with the distribution data to form the welding material distribution and recycling records required for relevant management. The secondary terminal is characterized by high stability, simple operation, and quick learning curve. With the addition of facial recognition functionality, it can minimize the problem of incorrect data recording. Furthermore, it can be deployed in clusters according to project needs, greatly improving welding material recycling efficiency and reducing the workload of warehouse managers.
[0031] Secondly, this application also provides an automatic welding wire feeding method, which uses an automatic feeding device with all the above-described structures to feed the welding wire, including the following steps: S1. First, the welder feeds the welding wire into the feed hopper. The welding wire in the receiving cavity is conveyed to the position of the roller by vibration. At the same time, the rotating shaft is driven by a servo motor to rotate. When the roller rotates to the limit groove corresponding to the welding wire, the welding wire will be stuck in the limit groove. Each limit groove corresponds to the conveying of one welding wire. The pressure plate above the roller can act as a barrier to prevent the welding wire from falling out of the limit groove during rotation. S2. As the rollers continue to rotate, the welding wire will gradually approach the discharge bin. At this time, the pressure plate will no longer block the welding wire. Under the action of the feeding guide plate, the welding wire in the limiting groove will be pushed into the discharge bin. At the same time, the counting sensor counts the number of welding wires passing through the area of the discharge bin, so as to achieve accurate counting of the target quantity.
[0032] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a feeding bin, a rotating shaft, rollers, a pressure plate, a feeding guide plate, a counting sensor, and a discharge bin, the welding wire is conveyed to the limiting groove of the rollers by vibration. The rollers periodically convey the welding wire, and the movement trajectory of the welding wire is arc-shaped. As the rollers convey the wire, the welding wire is pushed into the discharge bin by the pushing force of the feeding guide plate. The counting sensor on the side counts the number of welding wires falling from the rollers into the discharge bin, realizing automatic counting, replacing manual counting, and reducing the labor intensity of personnel.
[0033] (2) By setting a movable adjustment plate and a detachable strip block, it is convenient to count and discharge welding wires of different diameters, thereby improving the practicality of production. Attached Figure Description

[0036] The technical solutions of this application will now be described with reference to the accompanying drawings of the embodiments.

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[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 an automatic welding wire feeding device. (Refer to...) Figures 1 to 3 The automatic feeding device includes a frame 1, a feeding bin 2, a rotating shaft 3, rollers 4, a pressure plate 5, a feeding guide plate 6, a counting sensor 7, and a discharging bin 8. The frame 1 serves as a support carrier and is fixedly installed on the ground. A face recognition module 9 and a high-definition touchscreen 10 are installed on the frame 1, connected via a terminal. The face recognition module 9 is used to identify the welder's identity. The terminal can quickly identify the welder's identity information through the face recognition module 9, match it with the welding material distribution records in the data platform, retrieve the welder's material requisition information, and display it on the high-definition touchscreen 10. The feeding bin 2 is installed on the frame 1, with an opening forming a receiving cavity for storing welding wire. Support plates 29 are fixedly connected inside the feeding bin 2, with several support plates 29 spaced apart. The surfaces of the support plates 29 are sloped, and the welding wire is placed on the slopes of each support plate 29.
[0042] The rotating shaft 3 is located on the lower side of the slope and is rotatably connected to the frame 1 via a servo motor. The rotating shaft 3 is horizontally positioned. The rollers 4 are circular and coaxially mounted on the rotating shaft 3. Multiple rollers 4 can be spaced apart on the rotating shaft 3. Limiting grooves 11 are formed on the rollers 4 for engaging single welding wires. The welding wire in the feed bin 2 is vibrated and fed to the rollers 4 and engaged in the limiting grooves 11. Several limiting grooves 11 are formed on each roller 4, spaced apart along the circumference. The vibration of the feed bin 2 can be driven by mechanical vibration control, where a motor drives an eccentric block to rotate, generating centrifugal force that drives the wall of the feed bin 2 to vibrate. The vibration frequency is changed by adjusting the motor speed. This vibration control technology is existing and can be directly applied to this application; therefore, it will not be elaborated upon here.
[0043] During production, the welder first feeds a certain number of welding wires into the feed hopper 2. The welding wires in the hopper are then conveyed to the position of the roller 4 by vibration. At the same time, the rotating shaft 3 is driven to rotate by a servo motor. When the roller 4 rotates to the position of the limiting groove 11 corresponding to the position of the welding wire, the welding wire will be stuck in the limiting groove 11. Each limiting groove 11 corresponds to the conveying of one welding wire, realizing the continuous conveying of the welding wire.
[0044] A pressure plate 5 is installed above the roller 4. The pressure plate 5 is arc-shaped and is used to press the welding wire into the limiting groove 11, preventing the welding wire from detaching from the limiting groove 11 during rotation. The discharge bin 8 is installed on the side of the roller 4 away from the feed bin 2. The discharge bin 8 is used to receive the welding wire that falls from the limiting groove 11. The unloading guide plate 6 is fixedly installed on the frame 1 and close to the roller 4. The unloading guide plate 6 is used to push the welding wire on the limiting groove 11 into the discharge bin 8.
[0045] Specifically, the feeding guide plate 6 includes an arc-shaped segment 61 and a straight segment 62. The arc-shaped segment 61 is located at the upper end of the roller 4 and is arranged along the distribution direction of each limiting groove 11. The curvature of the arc-shaped segment 61 is the same as the curvature of the pressure plate 5. When the welding wire is clamped in the limiting groove 11, the welding wire is located between the arc-shaped segment 61 and the pressure plate 5. One end of the straight segment 62 is fixedly connected to the arc-shaped segment 61, and the other end of the straight segment 62 is inclined downward along the direction close to the discharge bin 8. The straight segment 62 is used to push the welding wire out of the limiting groove 11. The counting sensor 7 is installed on the frame 1 and is located between the feeding guide plate 6 and the discharge bin 8. The counting sensor 7 is used to count the welding wire falling into the discharge bin 8.
[0046] As roller 4 continues to rotate, the welding wire gradually approaches the discharge hopper 8 and leaves the area where pressure plate 5 is located. At this point, pressure plate 5 no longer blocks the welding wire. When the welding wire moves to the intersection of the arc segment 61 and the straight segment 62, the welding wire and the straight segment 62 move relative to each other (the straight segment 62 is stationary, while the welding wire rotates). At this time, the straight segment 62 will exert a component force on the welding wire, pushing the welding wire in the limiting groove 11 out and falling into the discharge hopper 8. At the same time, the counting sensor 7 will count the number of welding wires passing through this area of the discharge hopper, realizing automatic counting of welding wires, replacing manual counting, improving counting accuracy and production efficiency, and reducing the labor intensity of personnel.
[0047] The discharge hopper 8 is equipped with a baffle 12. One side of the baffle 12 is rotatably connected to the discharge hopper 8, while the other side is snapped or inserted into the frame 1. The baffle 12 is used to block the welding wire falling from the guide plate 6, preventing the welding wire from leaving the area of the discharge hopper 8 when it falls. When it is necessary to retrieve the material, the welder can overcome the friction to control the rotation of the baffle 12, thereby opening the opening of the discharge hopper 8 and making enough space for the operator to carry out the operation.
[0048] In this embodiment, an adjusting plate 13 is also installed inside the feeding hopper 2. The adjusting plate 13 is located above the plane of each support plate 29, and a gap is left between the adjusting plate 13 and the support plate 29. This gap allows only one row of welding wires to pass through, enabling the welding wires to approach the roller 4 in a single row, avoiding the welding wires from clustering together, and facilitating the single welding wire to be clamped onto the limiting groove 11. A first plate 14 and a second plate 15 are also installed on the frame 1. The first plate 14 and the second plate 15 are used to cover the opening of the feeding hopper 2 to prevent debris from entering the receiving cavity. The first plate 14 is fixedly connected to the frame 1, and the second plate 15 is rotatably connected to the first plate 14 via a hinge. A handle 16 for workers to grip is fixedly connected to the second plate 15. A magnetic snap is also installed at the opening of the feeding hopper 2, and the magnetic snap is magnetically attracted to the second plate 15. The presence of the magnetic snap can improve the connection stability between the second plate 15 and the feeding hopper 2, while not interfering with the opening and closing of the second plate 15. When feeding is required, the operator can grasp the handle 16, apply force to the second plate 15 and control the second plate 15 to rotate around the first plate 14 so as to put the welding wire into the receiving cavity.
[0049] Combination Figure 4 and Figure 5 In addition, the adjusting plate 13 is vertically movable and mounted on the frame 1. A vertically oriented slot 17 is provided on the adjusting plate 13, and a fastening screw passes through the slot 17 and is threaded onto the frame 1. A slot 18 is provided on the roller 4, and a slot 19 is detachably connected within the slot 18. A limiting groove 11 is provided along the length of the slot 19. Several slots 18 are provided, and each slot 18 contains a slot 19. Each slot 19 has a limiting groove 11. A recess 20 is also provided on the slot 19, which communicates with the slot 18. The slot 19 is locked onto the roller 4 by a fastening bolt located within the recess 20. One end of the fastening bolt passes through the slot 19 and is screwed onto the roller 4.
[0050] During production, to meet the counting and feeding requirements of welding wires with different diameters, the position of the adjusting plate 13 can be adjusted according to the welding wire specifications to change the distance between the adjusting plate 13 and the support plate 29. When adjusting the adjusting plate 13, the fastening screws must be loosened first, and then the adjusting plate 13 is moved up and down to the target position. During the movement, the fastening screws must always be in the slotted hole 17. Finally, the fastening screws are tightened again to fix the position of the adjusting plate 13.
[0051] Similarly, welding wires of different specifications require corresponding limiting grooves 11. During operation, first loosen the fastening bolts securing the strip block 19, remove the strip block 19 from the strip groove 18, and then replace it with a strip block 19 equipped with a corresponding limiting groove 11 and secure it. After the fastening bolts are tightened, they will fall into the recess 20 and will not interfere with the welding wire on the limiting groove 11.
[0052] The implementation principle of the automatic welding wire feeding device in this application embodiment is as follows: During production, the welder first puts a quantitative amount of welding wire into the feeding hopper 2. The welding wire in the receiving cavity is conveyed to the position of the roller 4 by vibration. The servo motor synchronously drives the rotating shaft 3 to rotate. When the roller 4 rotates to the position of the limiting groove 11 aligned with the welding wire, the welding wire will be stuck in the limiting groove 11. Each limiting groove 11 corresponds to the conveying of a single welding wire, thereby realizing the continuous supply of welding wire.
[0053] When the roller 4 drives the welding wire to rotate towards the discharge bin 8, the welding wire can smoothly pass between the arc segment 61 and the pressure plate 5 because the curvature of the arc segment 61 is consistent with the circular curvature formed by the limiting grooves 11. When the welding wire runs to the intersection of the arc segment 61 and the straight segment 62, the welding wire and the straight segment 62 move relative to each other. The straight segment 62 remains fixed, and the welding wire continues to rotate. At this time, the straight segment 62 will generate a component force on the welding wire, pushing the welding wire in the limiting groove 11 out and causing it to fall into the discharge bin 8.
[0054] During the feeding process, the counting sensor 7 counts the number of welding wires passing through the feeding bin area, achieving automatic wire counting. This method replaces manual counting, improving counting accuracy and production efficiency while reducing the labor intensity of workers.
[0055] Example 2 The difference between Embodiment 2 and Embodiment 1 lies in the disassembly and assembly structure of the strip block 19; this embodiment does not use fastening bolts for locking. (Refer to...) Figure 6 Specifically, the strip block 19 is equipped with a locking block 21, a first compression spring 22, a wedge block 23, a push block 24, a second compression spring 25, a U-shaped frame 26, and a push rod 27. The strip block 19 has a mounting groove 28. Two locking blocks 21 are symmetrically arranged and connected by the first compression spring 22, whose elastic force direction is along the width direction of the strip block 19. When the first compression spring 22 is in its natural state, part of the locking block 21 is located within the mounting groove 28, and the other part is engaged in a pre-set slot on the roller 4. The pre-set slot on the roller 4 is rectangular. The first compression spring 22 is located within the mounting groove 28, and the two locking blocks 21 are movably connected within the mounting groove 28.
[0056] Wedge blocks 23 are located within the mounting groove 28 and are fixedly connected to the locking blocks 21. Each locking block 21 has a wedge block 23, with the wedge-shaped surfaces of the two wedge blocks 23 facing the long sides of the strip block 19. The two ends of the second compression spring 25 are connected to the strip block 19 and the U-shaped frame 26, respectively. The direction of the spring force of the second compression spring 25 is parallel to the length direction of the strip block 19. Push blocks 24 are fixedly connected to the U-shaped frame 26, and two are symmetrically arranged. The push blocks 24 are slidably connected within the mounting groove 28. The movement of the push blocks 24 relies on the cooperation of a slider and a sliding groove; that is, a sliding groove is provided on the strip block 19, and a slider that cooperates with the sliding groove is connected to the push blocks 24. The two push blocks 24 are used to push the wedge-shaped surfaces of the two wedge blocks 23, and the two push blocks 24 are used to drive the two locking blocks 21 closer together. The push rod 27 is fixedly connected to the U-shaped frame 26 and is located at one end of the strip block 19. The length direction of the push rod 27 is parallel to the elastic force direction of the second compression spring 25.
[0057] During installation, the worker simultaneously pinches the two locking blocks 21 with both thumbs, compressing the first compression spring 22. The two locking blocks 21 move closer together and into the mounting groove 28, facilitating the gradual insertion of the strip block 19 into the strip groove 18. When the locking blocks 21 move into the preset groove on the roller 4, the first compression spring 22 releases its elastic force, causing the two locking blocks 21 to move away from each other and lock onto the roller 4, completing the installation of the strip block 19. At this point, the strip block 19 can no longer move along the strip groove 18.
[0058] When it is necessary to disassemble the strip block 19, the operator can apply force to the push rod 27. The push rod 27 drives the U-shaped frame 26 to move linearly, causing the two push blocks 24 to move synchronously and abut against the wedge-shaped surfaces of the two wedge blocks 23. This action will drive the two locking blocks 21 to move linearly and move closer to each other. After the two locking blocks 21 disengage from their corresponding slots, the strip block 19 can be removed from the strip groove 18. After the force on the push rod 27 is removed, the elastic force of the second compression spring 25 will cause the U-shaped frame 26 and the push blocks 24 to return to their initial positions.
[0059] Based on the above embodiments, this application also provides an automatic welding wire feeding method, which uses an automatic welding wire feeding device with all the above structures to count the fed welding wires, including the following steps: S1. First, the welder feeds the welding wire into the feed hopper 2. The welding wire in the hopper is conveyed to the position of the roller 4 by vibration. At the same time, the servo motor drives the rotating shaft 3 to rotate. When the roller 4 rotates to the position of the limiting groove 11 corresponding to the welding wire, the welding wire will be stuck in the limiting groove 11. Each limiting groove 11 is responsible for conveying a single welding wire. The pressure plate 5 above the roller 4 can act as a barrier to prevent the welding wire from falling out of the limiting groove 11 during rotation.
[0060] S2. As roller 4 continues to rotate, the welding wire gradually approaches the discharge bin 8. At this point, pressure plate 5 no longer obstructs the welding wire. Under the action of discharge guide plate 6, the welding wire in limit groove 11 is pushed into discharge bin 8. At the same time, counting sensor 7 counts the number of welding wires passing through the discharge bin area, achieving accurate counting of the target quantity.
[0061] 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.
