Description

Technical Field

[0001] This invention relates to the field of drain basket manufacturing technology, specifically to a spot welding machine and method for manufacturing wire drain baskets. Background Technology

[0002] The main body of the wire drain basket is woven or welded from 0.8-3mm stainless steel or galvanized steel wire. It features high weld density, high precision requirements for mesh spacing, thin and easily deformable wire walls, and a burr-free and burn-scar-free appearance. Traditional general-purpose resistance spot welding machines with their universal planar electrodes cannot match the arc-shaped contact characteristics of round wires, resulting in unstable contact area and uneven distribution of resistance heat, easily leading to problems such as incomplete welds, over-welds, or wire melting. Therefore, a spot welding machine based on the wire drain basket was developed. It utilizes the resistance heat generated by current passing through the metal contact points to locally melt the metal while simultaneously applying... Applying pressure forms strong weld points without the need for consumables such as welding wire and flux. The welding process is environmentally friendly with no strong light and a small heat-affected zone, effectively preventing deformation of thin wires and damage to the plating. For the special structure of the drain basket, these welding machines generally adopt medium-frequency inverter power supply technology, which provides stable DC output current and precise and controllable heat input, resulting in good weld point consistency and uniform tension. They are also equipped with custom tooling molds that can be quickly replaced, which can accurately position the basket frame and mesh wires, significantly solving the industry pain points of traditional AC welding machines, such as many burrs, easy cold welds, and easy rusting later.

[0003] In actual production applications, existing wire deflector welding machines often encounter problems. Due to residual internal stress from the uncoiling and leveling process of the wire, as well as the elastic deformation characteristics of the circular cross-section, the wire may not fully engage with the bottom of the positioning groove during manual or mechanical placement. This results in a gap between the wire and the bottom of the groove, which can lead to slight deviations in the wire's position during welding. This affects the accuracy of the weld and the overall flatness of the mesh. Furthermore, during long-term continuous production, spatter formed by the ejection of locally molten metal droplets under electromagnetic force and thermal expansion during welding gradually accumulates at the bottom and sidewall gaps of the positioning groove, gradually raising the positioning reference surface. This not only affects the positioning accuracy of the subsequent wire but may also impact the stable conduction of the welding current.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide a spot welding machine and method based on a wire drain basket, in order to solve the problems mentioned in the background art, such as the easy springback of wires, resulting in installation gaps and the accumulation of welding impurities. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spot welding machine and method based on a wire drain basket, comprising a main body, wherein a side fixing seat and a main fixing seat are provided inside the main body, the surface of the main fixing seat is provided with a plurality of grooves for fixing the wire, a fixing component is provided inside the main fixing seat, a cleaning seat is fixed to the side wall of the main fixing seat, and a cleaning component is provided inside the cleaning seat; The cleaning assembly includes a rotating column rotatably installed in the cleaning seat and a sliding rod fixed in the cleaning seat. The rotating column has a reciprocating groove on its surface, a sliding block is slidably installed in the reciprocating groove, a cleaning brush is fixed on the surface of the sliding block, and a rotating disk is installed at the end of the rotating column. A one-way gear is provided on the surface of the rotating disk. It also includes a transmission disc rotatably installed in the cleaning seat, the side wall of the transmission disc being elastically rotatably connected with one-way teeth, a transmission bevel gear fixed on the surface of the transmission disc, a drive bevel gear rotatably installed in the cleaning seat, a drive wheel fixed on the side wall of the drive bevel gear, and a drive rack fixed to the side wall of the side fixing seat.

[0007] Preferably, the sliding block is slidably mounted on the surface of the sliding rod, and the shape of the cleaning brush corresponds to the groove on the surface of the main fixing seat.

[0008] Preferably, the transmission disk is located inside the rotating disk, and the one-way teeth mesh with the one-way gear.

[0009] Preferably, a coil spring is provided inside the transmission disc, and the transmission disc is connected to the cleaning seat through the coil spring.

[0010] Preferably, the driving bevel gear meshes with the transmission bevel gear, and the driving wheel meshes with the driving rack.

[0011] Preferably, the fixing component includes a sliding plate that is elastically slidably installed in a groove on the surface of the main fixing seat, a sliding column fixed at the bottom of the sliding plate, two sets of connecting rods rotatably installed on the surface of the sliding column, a one-way rack fixed on the surface of the sliding column, and two sets of clamping plates symmetrically rotatably installed in the main fixing seat. It also includes a pawl that is rotatably mounted in the main fixed seat, and a reset rod that is elastically limited and slidable in the main fixed seat, wherein multiple reset blocks are fixed on the surface of the reset rod.

[0012] Preferably, the clamping plates are symmetrically distributed on both sides of the groove on the surface of the main fixing seat, and the clamping plates are connected to the sliding column through a connecting rod.

[0013] Preferably, the one-way rack engages with the pawl, the reset block is designed to be inclined, and the position of the reset block corresponds to that of the pawl.

[0014] Preferably, the method includes the following steps: S1: The side fixing seat moves towards the main fixing seat, driving the cleaning component to pre-clean the grooves on the surface of the main fixing seat; S2: The wire is placed in the groove and the sliding plate is pressed down.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of a main fixing seat and fixing components, achieves the limiting and reliable clamping of the wire. The main fixing seat has a limiting groove on its surface. The fixing components are triggered by the weight of the wire itself to automatically clamp both sides of the wire. Together with the one-way rack and pawl, they form a self-locking mechanism to offset the internal stress remaining after the wire is unwound and leveled and the vibration generated by welding. This avoids the problem of the wire springing back and not being fully inserted into the groove bottom, ensuring the stability of the wire position during welding and eliminating defects such as weld point offset and uneven penetration caused by installation gaps. At the same time, the clamping surface of the clamping plate is equipped with an elastic rubber pad to take into account the clamping needs of wires of different diameters, ensuring clamping force to prevent rotation and avoiding damage to the wire surface, thereby improving the welding qualification rate and product consistency.

[0016] 2. This invention, through the setting of a side fixing seat, a cleaning seat, and a cleaning component, cleans the groove before and after welding, simplifying the manual operation process, removing residual welding spatter and metal debris from the previous round, ensuring that the wire can completely fit the bottom reference surface of the groove, and also completing post-weld cleaning, promptly removing spatter generated during the current welding, avoiding problems such as decreased positioning accuracy, increased contact resistance, and incomplete weld joints caused by spatter accumulation, which affect the welding work, ensuring the long-term stability of welding quality, and improving the continuous production efficiency of the equipment.

[0019] Please see Figures 1-10 The present invention provides a technical solution: a spot welding machine and method based on a wire drain basket, comprising a main body 1, a side fixing seat 101 and a main fixing seat 2 are provided in the main body 1, a plurality of grooves for fixing wires are opened on the surface of the main fixing seat 2, a fixing component is provided in the main fixing seat 2, a cleaning seat 201 is fixed on the side wall of the main fixing seat 2, and a cleaning component is provided in the cleaning seat 201. The cleaning assembly includes a rotating column 5 rotatably installed in the cleaning seat 201 and a sliding rod 602 fixed in the cleaning seat 201. The rotating column 5 has a reciprocating groove 501 on its surface, a sliding block 601 is slidably installed in the reciprocating groove 501, a cleaning brush 6 is fixed on the surface of the sliding block 601, a rotating disk 502 is installed at the end of the rotating column 5, and a one-way gear 503 is provided on the surface of the rotating disk 502. It also includes a transmission disc 7 rotatably installed in the cleaning seat 201. The side wall of the transmission disc 7 is elastically rotatably connected with a one-way tooth 701. A transmission bevel gear 703 is fixed on the surface of the transmission disc 7. A drive bevel gear 704 is rotatably installed in the cleaning seat 201. A drive wheel 705 is fixed on the side wall of the drive bevel gear 704. It also includes a drive rack 102 fixed on the side wall of the side fixing seat 101. The cleaning assembly is directly aligned with the positioning groove on the surface of the main fixing seat 2 to reduce alignment deviation.

[0020] In one embodiment of the present invention, the sliding block 601 is slidably mounted on the surface of the sliding rod 602. The shape of the cleaning brush 6 corresponds to the groove on the surface of the main fixing seat 2. The sliding rod 602 provides a limit for the movement of the sliding block 601, so that it can only slide in a straight line to avoid deviation during movement. The bristle contour of the cleaning brush 6 is processed according to the groove on the surface of the main fixing seat 2, which can penetrate into the bottom and side wall gaps of the groove and form a uniform contact pressure with the groove wall, making it easy to remove welding spatter, oxide scale and metal debris remaining in various corners of the groove.

[0021] In one embodiment of the present invention, the transmission disk 7 is located inside the rotating disk 502, and the one-way teeth 701 mesh with the one-way gear 503. The nested structure ensures the coaxiality of the transmission disk 7 and the rotating disk 502, and is more conducive to the meshing transmission of the one-way teeth 701 and the one-way gear 503. When the transmission disk 7 rotates forward, the elastically installed one-way teeth 701 pop out and mesh tightly with the one-way gear 503, transmitting power to the rotating disk 502 to drive the cleaning brush 6 to move. When the transmission disk 7 rotates in reverse, the one-way teeth 701 are squeezed inward by the tooth surface of the one-way gear 503 and retract to avoid it, disengaging from the mesh.

[0022] In one embodiment of the present invention, a coil spring 702 is provided inside the transmission disk 7. The transmission disk 7 is connected to the cleaning seat 201 through the coil spring 702. When the side fixed seat 101 moves linearly, the drive rack 102 meshes with the drive wheel 705 to drive the transmission disk 7 to rotate. The coil spring 702 stores elastic potential energy and releases energy when it disengages, providing reciprocating motion power for the cleaning brush 6.

[0023] In one embodiment of the present invention, the drive bevel gear 704 meshes with the transmission bevel gear 703 to realize the reversal of power and ensure the stability of power transmission. The drive wheel 705 meshes with the drive rack 102, and the cleaning component is driven by the movement of the side fixing seat 101 without the need for an additional power source.

[0024] As one embodiment of the present invention, the fixing component includes a sliding plate 3 elastically slidably installed in a groove on the surface of the main fixing seat 2, a sliding column 301 fixed at the bottom of the sliding plate 3, two sets of connecting rods 303 rotatably installed on the surface of the sliding column 301, a one-way rack 302 fixed on the surface of the sliding column 301, and two sets of clamping plates 304 symmetrically rotatably installed in the main fixing seat 2. When the wire to be welded falls into the groove, it can press down the sliding plate 3 by its own weight, drive the sliding column 301 down, and pull the clamping plates 304 on both sides to simultaneously close inward and clamp the wire through the connecting rods 303; It also includes a pawl 4 rotatably mounted in the main fixed seat 2, and a reset rod 401 elastically limited and slidable in the main fixed seat 2, with multiple reset blocks 402 fixed on the surface of the reset rod 401.

[0025] In one embodiment of the present invention, the clamping plates 304 are symmetrically distributed on both sides of the groove on the surface of the main fixing seat 2, which ensures the uniformity of the clamping force applied to the wire and avoids lateral displacement of the wire, and keeps it in the center position. The clamping plates 304 are connected to the sliding column 301 through the connecting rod 303. When the sliding column 301 is pressed down by the wire, the two sets of connecting rods 303 simultaneously pull the clamping plates 304 on both sides to rotate inward around the axis point to complete the clamping action. When the sliding column 301 moves up to reset, it pushes the clamping plates 304 on both sides to open outward and release the clamping.

[0026] In one embodiment of the present invention, the one-way rack 302 meshes with the pawl 4. The elastically installed pawl 4 and the one-way rack 302 form a one-way transmission. When the wire presses down on the sliding column 301 and drives the one-way rack 302 downward, the pawl 4 swings around the axis to avoid it and does not obstruct the movement. When the wire rebounds and tends to rise due to the residual internal stress of unwinding and leveling, the pawl 4 is engaged with the one-way rack 302 under the action of the return spring, forming a locking structure to prevent the sliding column 301 from moving upward. The return block 402 is designed with an inclination and its position corresponds to the pawl 4. Pushing the return rod 401 drives the return block 402 to squeeze the pawl 4, which can make the pawl 4 rotate to disengage. The sliding column 301 can move upward to reset under the force of the return spring.

[0027] As one embodiment of the present invention, the method includes the following steps: S1: The side fixing seat 101 moves toward the main fixing seat 2, driving the cleaning component to pre-clean the grooves on the surface of the main fixing seat 2; S2: The wire is placed in the groove and the sliding plate 3 is pressed down. The sliding column 301 drives the clamping plate 304 to clamp the wire through the connecting rod 303. The pawl 4 and the one-way rack 302 self-lock and fix the position. S3: After welding is completed, the side fixing seat 101 is retracted, the reset rod 401 is manually pushed to unlock the pawl 4 and the one-way rack 302, the sliding plate 3 automatically lifts the workpiece for unloading, the side fixing seat 101 is retracted, and the cleaning assembly is driven to complete the post-weld cleaning work.

[0028] Working principle: When using the spot welding machine based on the wire drain basket, first adjust the position of the side fixing seat 101 so that it is close to the main fixing seat 2. As the side fixing seat 101 moves, the drive rack 102 fixed on the side wall of the side fixing seat 101 gradually extends into the cleaning seat 201 and meshes with the drive wheel 705 in the cleaning seat 201. Through the meshing of the drive bevel gear 704 and the transmission bevel gear 703, the transmission disk 7 is driven to start rotating forward. At this time, the one-way tooth 701 and the one-way gear 503 set on the side wall of the rotating disk 502 are meshed. The one-way gear 503 directly drives the rotating disk 502 to start rotating. At the same time, the coil spring 702 in the transmission disk 7 is gradually stretched and stores elastic potential energy. As the side fixing seat 101 moves, the rotating disk 502 gradually rotates, driving the rotating column 5 to rotate synchronously. A sliding block 601 is slidably installed in the reciprocating groove 501 opened on the surface of the rotating column 5, and the sliding block 601 is slidably installed on the surface of the sliding rod 602 fixed in the cleaning seat 201. While the rotating column 5 rotates, the sliding block 601 gradually drives the cleaning brush 6 to perform reciprocating linear motion. The shape of the cleaning brush 6 fits the groove design opened on the surface of the main fixing seat 2, and can penetrate into the bottom and side wall gaps of the groove to pre-clean the welding spatter, oxide scale and metal shavings remaining in the groove before processing. The side fixing seat 101 is moved until the driving rack 102 disengages from the driving wheel 705 and stops. At this time, there is still an installation gap between the side fixing seat 101 and the main fixing seat 2. After the coil spring 702 loses its external limit, it begins to rewind and reset, driving the transmission disk 7 to reverse. At this time, the one-way tooth 701 will adaptively rotate inward to avoid it, not engaging with the rotating disk 502, and not driving the rotating disk 502 to rotate. The wires are then placed sequentially into the grooves on the surface of the main fixing seat 2. As the wires fall, they contact and press against the surface of the sliding plate 3, which in turn pushes the sliding column 301 downwards in the vertical direction. The sliding column 301 is connected to the clamping plates 304 on both sides via two sets of symmetrically arranged connecting rods 303. As the sliding column 301 descends, it pulls the clamping plates 304 to rotate around the axis, gradually clamping both sides of the wire. The one-way rack 302 fixed at the bottom of the sliding column 301 descends synchronously, and the one-way rack 302 engages with the pawl 4 in one direction. 2. During descent, the elastically mounted pawl 4 will automatically shift to avoid the one-way rack 302, allowing it to descend smoothly. When the one-way rack 302 tends to move upward due to wire rebound or vibration, the pawl 4 engages with the one-way rack 302 under the elastic force of the return spring, preventing the one-way rack 302 from rising and ensuring the stability of the position of the one-way rack 302, thereby ensuring the stability of wire clamping. At the same time, the surface of the clamping plate 304 is provided with an elastic rubber pad to provide sufficient clamping friction for small-diameter wires, while avoiding indentation or deformation on the surface of large-diameter wires. After the wire is installed, start the side fixing seat 101 again to move it towards the main fixing seat 2 until it is completely close to the wire fixed on the surface of the main fixing seat 2, so as to completely fix the position of the wire and facilitate subsequent welding processing. After the welding process is completed, the rear side fixing seat 101 is retracted and moved to a position where the drive rack 102 is not engaged with the drive wheel 705. At this time, the reset rod 401 is manually pushed. The reset rod 401 drives the surface-mounted reset block 402 to move synchronously into the main fixing seat 2. The reset block 402 is designed with an inclination and is in close contact with the side wall of the pawl 4. As the reset block 402 moves, the inclination side wall of the reset block 402 squeezes the side wall of the pawl 4, causing it to rotate around the axis point and move away from the one-way rack 302. After the one-way rack 302 loses the limitation of the pawl 4, it moves upward quickly under the elastic force of the reset spring to return to its original position, driving the sliding plate 3 to rise synchronously. At the same time, it releases the clamping limitation on the wire and lifts the wire after processing, making it easier for the subsequent workers to take out the workpiece. After the processed workpiece is removed, the side fixed seat 101 continues to move away from the main fixed seat 2. As the side fixed seat 101 retracts, the drive rack 102 gradually meshes with the drive wheel 705 again, causing the drive transmission disk 7 to rotate in the opposite direction. At this time, the one-way tooth 701 adaptively rotates into the transmission disk 7 to avoid meshing with the rotating disk 502 and does not drive the rotating disk 502 to rotate, so that the rotating column 5 can remain stationary for a period of time, allowing the operator time to react and preventing the situation where the workpiece is forgotten and the reaction is not timely. The rotation of the transmission disk 7 drives the coil spring 702 to coil and store elastic force. When the side fixed seat 101 moves to the point where the drive rack 102 disengages from the drive wheel 705, the coil spring 702 quickly releases the stored elastic potential energy, driving the transmission disk 7 to rotate forward, driving the rotating disk 502 to rotate, and driving the cleaning brush 6 to perform reciprocating linear motion to clean the groove after processing, removing the spatter and metal debris generated during this welding process, and preparing for the next welding cycle.
