Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to an automatic welding solder feeding device and an automatic welding solder feeding method. Background Technology

[0002] According to the product design requirements, the processed copper busbars and copper bars need to be welded together. During welding, the copper busbars, solder, and copper bars need to be placed in sequence from bottom to top. The copper busbars and copper bars are semi-finished products that need to be welded. The solder is used as an auxiliary material. After the solder melts, it melts and mixes with the semi-finished products that need to be welded to form a weld with good conductivity and strength.

[0003] Currently, the production process mainly uses manual placement. First, the copper busbar is placed at the bottom of the welding area, then the solder is placed on the copper busbar, and finally the copper bar material is placed on top of the solder. After confirming that the placement is correct, the welding equipment is started to perform pressure welding to complete the welding process.

[0004] Therefore, there is an urgent need for automated solder feeding equipment and methods to solve the above problems. Summary of the Invention

[0005] The first objective of this invention is to provide an automatic welding material feeding device to replace the existing manual welding material feeding solution, reduce the occurrence of manual omissions, misplacements, and improper placement, improve operation time and efficiency, and enhance welding material feeding efficiency and accuracy.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] The system comprises a frame, a first drive mechanism, a first mounting plate, a second drive mechanism, and a second mounting plate. The first drive mechanism is mounted on the frame, and the first mounting plate is located at the output end of the first drive mechanism. The first drive mechanism is configured to drive the first mounting plate to move along the X-axis. The second drive mechanism is mounted on the first mounting plate, and the second mounting plate is located at the output end of the second drive mechanism. The second drive mechanism is configured to drive the second mounting plate to move along the Y-axis. The X-axis and Y-axis are perpendicular to each other.

[0009] The conveying and positioning device, mounted on the second mounting plate, includes a feeding mechanism, a tensioning mechanism, a feeding mechanism, and a guiding structure arranged sequentially along the Y-axis. The feeding mechanism is configured to fix and release the solder strip. The tensioning mechanism is configured to detect the tension of the solder strip and control the feeding mechanism to start and stop by a tension feedback signal. The feeding mechanism is configured to convey the solder strip of a preset length to the guiding structure. The guiding structure is configured to guide the solder strip to the welding area. When the second mounting plate moves along the Y-axis, it can drive the entire conveying and positioning device to switch between an idle station and a docking station.

[0010] The cutting device includes a third drive mechanism, a fourth drive mechanism, and a cutting mechanism.

The rotary motor can drive the rotating shaft to rotate and drive the solder reel to rotate synchronously to feed the solder.

[0014] Two limiting baffles are sleeved on the rotating shaft and located on both sides of the solder tray, respectively abutting against both sides of the solder tray. The rotating shaft is fixed with the two limiting baffles by interference fit. The limiting baffles are configured to restrict the solder tray from moving axially along the rotating shaft.

[0018] A baffle plate is fixed to the side of the positioning rod. The solder strip is sequentially wrapped around the upper surface of the first guide roller, the lower surface of the positioning rod, and the upper surface of the second guide roller so that the solder strip is arranged in a U-shape. The positioning rod moves upward along the guide rail under the support of the solder strip, or moves downward along the guide rail under its own gravity, so as to drive the baffle plate to move up and down synchronously along the Z-axis.

[0019] The lower sensor and the upper sensor are both fixed on the second mounting plate and are spaced apart along the Z-axis direction. They correspond to the lower limit movement position and the upper limit movement position of the positioning rod, respectively.

The pressing plate is connected to the output end of the pressing cylinder. The pressing cylinder can drive the pressing plate to reciprocate along the Z-axis direction to press and fix or loosen the solder strip sandwiched between the pressing plate and the support plate.

[0023] The clamping assembly includes an actuating cylinder, an opening / closing cylinder, and a gripper. The actuating cylinder is fixed to the second mounting plate, the opening / closing cylinder is located at the output end of the actuating cylinder, and the gripper is located at the output end of the opening / closing cylinder.

The connecting end of the limiting rod is connected to the end of the piston rod of the actuating cylinder opposite to the opening and closing cylinder. The limiting end of the limiting rod passes through the cylinder body of the actuating cylinder on the side opposite to its output end and extends outward. The limiting end of the limiting rod is also provided with a limiting protrusion, which is configured to limit the extension stroke of the piston rod along the Y-axis by abutting against the end face of the cylinder body of the actuating cylinder, thereby limiting the feeding length of the solder strip.

[0032] The first motor can drive the first lead screw to rotate, causing the first nut to move along the X-axis direction, and the first slider to slide synchronously along the first slide rail, thereby guiding the first mounting plate to move linearly along the X-axis direction, so that the position of the conveying positioning device and the cutting device along the X-axis direction is adjustable.

[0033] As an optional solution for an automated solder loading device, the second drive mechanism includes:

[0036] The second cylinder can drive the second slider to move along the Y-axis direction, and the second slider slides along the second slide rail, thereby guiding the second mounting plate to move linearly along the Y-axis direction, so that the conveying and positioning device can switch between the idle station and the docking station.

[0037] The second objective of this invention is to provide an automatic solder feeding method for welding, which is applied to the aforementioned automatic solder feeding equipment to replace the existing manual solder feeding scheme, reduce human intervention errors, and significantly improve the efficiency and accuracy of solder feeding.

[0038] To achieve this objective, the present invention adopts the following technical solution:

[0039] An automatic solder feeding method for welding, applied to the aforementioned automatic solder feeding equipment, includes the following steps:

[0040] Step S1: The first driving mechanism drives the first mounting plate to move along the X-axis direction, which in turn drives the second mounting plate, the conveying and positioning device and the cutting device to move synchronously along the X-axis direction to adapt to the position requirements of the corresponding welding area in the X-axis direction.

[0041] Step S2: In the initial state, the conveying and positioning device is in the idle station, the cutting mechanism is in the avoidance station, the third drive mechanism drives the fourth drive mechanism to move along the Y-axis direction, and drives the cutting mechanism to move synchronously to adjust the cutting length of the solder strip in the future.

[0042] Step S3: The second drive mechanism drives the second mounting plate to move along the Y-axis, which in turn drives the conveying and positioning device to move synchronously along the Y-axis, switching from the idle station to the docking station. The feeding mechanism fixes and releases the solder strip. The tensioning mechanism detects the tension of the solder strip and controls the feeding mechanism to start and stop by the tension feedback signal. The feeding mechanism conveys the solder strip of a preset length to the guide structure. The guide structure guides the solder strip to the welding area.

[0043] Step S4: After welding is completed, the second drive mechanism drives the second mounting plate to move along the Y-axis, causing the conveying and positioning device to move synchronously along the Y-axis, switching from the docking station to the idle station; the fourth drive mechanism drives the cutting mechanism to move along the X-axis, switching from the avoidance station to the cutting station, and the cutting mechanism cuts the solder strip between the guide structure and the welding area; after the cutting mechanism completes the cutting of the solder strip, the fourth drive mechanism drives the cutting mechanism to move along the X-axis, switching from the cutting station to the avoidance station;

[0044] Step S5: Repeat steps S3-S4 thereafter.

[0045] The beneficial effects of this invention are:

[0046] This invention provides an automatic welding solder feeding device. During operation, a first drive mechanism on the frame drives a first mounting plate to move along the X-axis, causing a second drive mechanism, a second mounting plate, a conveying and positioning device, and a cutting device to adapt to the welding area's position along the X-axis. The second drive mechanism drives the second mounting plate to switch the conveying and positioning device between an idle station and a docking station. In the docking station, the feeding mechanism releases the solder strip, the tensioning mechanism detects the tension and controls the start and stop of the feeding, and the feeding mechanism conveys a solder strip of a preset length to the welding area via a guide structure. The third drive mechanism of the cutting device drives a fourth drive mechanism to adjust the cutting length along the Y-axis, and the cutting mechanism is positioned in a avoidance station to avoid the docking path. After welding is completed, the conveying and positioning device switches to an idle station, and the fourth drive mechanism drives the cutting mechanism to switch to the cutting station, cutting the solder strip between the guide structure and the welding area. The cutting mechanism then returns to the avoidance station. Repeating the above process achieves automatic solder feeding, conveying, and cutting. This automatic welding material feeding equipment precisely controls the length and positioning accuracy of the welding material through the coordinated movement of multiple mechanisms, replacing manual operation, reducing manual omissions, misplacements, and improper placement, lowering labor costs and positioning errors, improving operation time and efficiency, enhancing welding material feeding efficiency and accuracy, and significantly improving the automation level and production efficiency of the welding process.

[0047] This invention also provides an automatic solder feeding method for welding, applied to the aforementioned automatic solder feeding equipment. A first driving mechanism drives a first mounting plate to move along the X-axis, quickly adapting to the X-axis position requirements of the welding area. A second driving mechanism drives a second mounting plate to switch between an idle station and a docking station. A tensioning mechanism detects the solder strip tension in real time and provides feedback to control the feeding mechanism's start and stop. A feeding mechanism precisely feeds a preset length of solder strip to a guide structure, which stably guides the solder strip to the welding area. A fourth driving mechanism drives a cutting mechanism to switch between an avoidance station and a cutting station to complete precise cutting. This automatic solder feeding method achieves automatic solder feeding, positioning, guiding, and cutting, replacing existing manual solder feeding methods. It reduces human intervention errors, lowers labor costs, increases operating time and efficiency, and reduces manual omissions, misplacements, and improper placement, significantly improving welding feeding efficiency and accuracy.

[0074] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0075] like Figures 1-2As shown, this embodiment provides an automatic solder feeding device and an automatic solder feeding method. The automatic solder feeding device includes a frame 1, a first drive mechanism 21, a first mounting plate 22, a second drive mechanism 31, a second mounting plate 32, a conveying and positioning device 4, and a cutting device 5. The first drive mechanism 21 is disposed on the frame 1, and the first mounting plate 22 is disposed at the output end of the first drive mechanism 21. The first drive mechanism 21 is used to drive the first mounting plate 22 to move along the X-axis direction. The second drive mechanism 31 is disposed on the first mounting plate 22, and the second mounting plate 32 is disposed at the output end of the second drive mechanism 31. The second drive mechanism 31 is used to drive the second mounting plate 32 to move along the Y-axis direction. The X-axis direction and the Y-axis direction are perpendicular to each other. The conveying and positioning device 4 is mounted on the second mounting plate 32 and includes a feeding mechanism 41, a tensioning mechanism 42, a feeding mechanism 43, and a guiding structure 44 arranged sequentially along the Y-axis. The feeding mechanism 41 is used to fix and release the solder strip 100. The tensioning mechanism 42 is used to detect the tension of the solder strip 100 and control the feeding mechanism 41 to start and stop by the tension feedback signal. The feeding mechanism 43 is used to convey the solder strip 100 of a preset length to the guiding structure 44. The guiding structure 44 is used to guide the solder strip 100 to the welding area. When the second mounting plate 32 moves along the Y-axis, it can drive the entire conveying and positioning device 4 to switch between an idle station and a docking station. The cutting device 5 includes a third drive mechanism 51, a fourth drive mechanism 52, and a cutting mechanism 53. The third drive mechanism 51 is mounted on the first mounting plate 22, the fourth drive mechanism 52 is located at the output end of the third drive mechanism 51, and the cutting mechanism 53 is located at the output end of the fourth drive mechanism 52. The fourth drive mechanism 52 drives the cutting mechanism 53 to move along the X-axis and switches between a cutting station and a retraction station. The cutting mechanism 53 cuts the solder strip 100 between the guide structure 44 and the welding area. The third drive mechanism 51 drives the fourth drive mechanism 52 to move along the Y-axis, causing the cutting mechanism 53 to move synchronously, so that the cutting length of the solder strip 100 is adjustable. When the conveying and positioning device 4 is in an idle station, the cutting mechanism 53 is located in the cutting station to cut the solder strip 100. When the conveying and positioning device 4 is in the docking station, the guide structure 44 docks with the welding area, and the cutting mechanism 53 is located in the retraction station to avoid the docking path between the guide structure 44 and the welding area.

[0076] When the automatic welding feeder is working, the first drive mechanism 21 on the frame 1 drives the first mounting plate 22 to move along the X-axis, which in turn drives the second drive mechanism 31, the second mounting plate 32, the conveying and positioning device 4, and the cutting device 5 to adapt to the welding area in the X-axis direction. The second drive mechanism 31 drives the second mounting plate 32 to switch the conveying and positioning device 4 between an idle station and a docking station. In the docking station state, the feeding mechanism 41 releases the welding strip 100, the tensioning mechanism 42 detects the tension and controls the start and stop of the feeding, and the feeding mechanism 43 conveys the welding strip of a preset length. The solder strip 100 is fed to the welding area via the guide structure 44. The third drive mechanism 51 of the cutting device 5 drives the fourth drive mechanism 52 to move the cutting mechanism 53 to adjust the cutting length along the Y-axis, and the cutting mechanism 53 is positioned at the avoidance station to avoid the docking path. After welding is completed, the conveying and positioning device 4 switches to the idle station, and the fourth drive mechanism 52 drives the cutting mechanism 53 to switch to the cutting station, cutting the solder strip 100 between the guide structure 44 and the welding area. Then the cutting mechanism 53 returns to the avoidance station, and the above process is repeated to realize automatic solder feeding, conveying and cutting. This automatic solder feeding equipment accurately controls the solder conveying length and positioning accuracy through the coordinated movement of multiple mechanisms, replacing manual operation, reducing manual omissions, misplacements, and improper placement, reducing labor costs and positioning errors, improving operation time and efficiency, improving welding feeding efficiency and accuracy, and significantly improving the automation level and production efficiency of the welding process.

[0077] like Figures 1-2 As shown, the automatic solder feeding method of this embodiment is applied to the above-mentioned automatic solder feeding equipment. The automatic solder feeding method includes the following steps:

[0078] Step S1: The first drive mechanism 21 drives the first mounting plate 22 to move along the X-axis, which in turn drives the second mounting plate 32, the conveying and positioning device 4 and the cutting device 5 to move synchronously along the X-axis to adapt to the position requirements of the corresponding welding area in the X-axis direction.

[0079] Step S2: In the initial state, the conveying and positioning device 4 is in an idle position, the cutting mechanism 53 is in a non-positioning position, the third driving mechanism 51 drives the fourth driving mechanism 52 to move along the Y-axis, and drives the cutting mechanism 53 to move synchronously to adjust the cutting length of the subsequent solder strip 100.

[0080] Step S3: The second drive mechanism 31 drives the second mounting plate 32 to move along the Y-axis, which in turn drives the conveying and positioning device 4 to move synchronously along the Y-axis, switching from the idle station to the docking station. The feeding mechanism 41 fixes and releases the solder strip 100. The tensioning mechanism 42 detects the tension of the solder strip 100 and controls the feeding mechanism 41 to start and stop by releasing the material through the tension feedback signal. The feeding mechanism 43 conveys the solder strip 100 of the preset length to the guide structure 44. The guide structure 44 guides the solder strip 100 to the welding area.

[0081] Step S4: After welding is completed, the second drive mechanism 31 drives the second mounting plate 32 to move along the Y-axis, which in turn drives the conveying and positioning device 4 to move synchronously along the Y-axis, switching from the docking station to the idle station; the fourth drive mechanism 52 drives the cutting mechanism 53 to move along the X-axis, switching from the avoidance station to the cutting station, and the cutting mechanism 53 cuts the solder strip 100 between the guide structure 44 and the welding area; after the cutting mechanism 53 completes the cutting of the solder strip 100, the fourth drive mechanism 52 drives the cutting mechanism 53 to move along the X-axis, switching from the cutting station to the avoidance station;

[0082] Step S5: Repeat steps S3-S4 thereafter.

[0083] The first drive mechanism 21 drives the first mounting plate 22 to move along the X-axis, which can quickly adapt to the position requirements of the welding area in the X-axis direction. The second drive mechanism 31 drives the second mounting plate 32 to move the conveying and positioning device 4 between the idle station and the docking station. The tensioning mechanism 42 detects the tension of the solder strip 100 in real time and feeds back to control the feeding mechanism 41 to start and stop feeding. The feeding mechanism 43 accurately conveys the solder strip 100 of the preset length to the guide structure 44. The guide structure 44 stably guides the solder strip 100 to the welding area. The fourth drive mechanism 52 drives the cutting mechanism 53 to switch between the avoidance station and the cutting station to complete the precise cutting. This automatic solder feeding method realizes automatic solder feeding, positioning, guiding and cutting, replacing the existing manual solder feeding scheme, reducing manual intervention error, reducing labor costs, improving operation time and operation efficiency, reducing manual omission, misplacement and improper placement, and greatly improving the efficiency and accuracy of solder feeding.

[0084] It is worth noting that, such as Figure 1 As shown in the initial state, the conveying positioning device 4 is in an idle position far from the welding area, and the cutting mechanism 53 is located in a avoidance position far from the guide structure 44. When the conveying positioning device 4 needs to be docked, the conveying positioning device 4 moves from the idle position along the Y-axis to the docking position close to the welding area. When the cutting mechanism 53 needs to cut, the cutting mechanism 53 moves from the avoidance position along the X-axis to the cutting position close to the guide structure 44.

[0085] like Figures 1-2As shown, the first drive mechanism 21 includes a first motor, a first lead screw 211, a first nut, a first slide rail 212, and a first slider. The first motor is fixed to the frame 1. The first lead screw 211 extends along the X-axis and is connected to the output end of the first motor. The first lead screw 211 is threaded through the first nut, and the first nut is connected to the first mounting plate 22. The first slide rail 212 extends along the X-axis and is fixed to the frame 1. The first slider is slidably disposed on the first slide rail 212 and connected to the first mounting plate 22. The first motor can drive the first lead screw 211 to rotate, thereby causing the first nut to move along the X-axis. The first slider slides synchronously along the first slide rail 212, thereby guiding the first mounting plate 22 to move linearly along the X-axis, so that the positions of the conveying positioning device 4 and the cutting device 5 are adjustable along the X-axis. The threaded engagement between the first lead screw 211 and the first nut, combined with the guiding effect of the first slide rail 212 and the first slider, enables the first mounting plate 22 to achieve high-precision linear motion along the X-axis direction. This significantly improves the position adjustment accuracy and stability of the conveying positioning device 4 and the cutting device 5 in the X-axis direction, reduces motion deviation, ensures precise alignment with the welding area, and provides reliable power and guiding support for the overall automated operation of the automatic welding material feeding equipment.

[0086] like Figures 1-2 As shown, the second drive mechanism 31 includes a second slide rod 311, a second sliding member, a second cylinder, a second slide rail 312, and a second slider. The second slide rod 311 extends along the Y-axis and is fixed on the first mounting plate 22. The second sliding member is slidably sleeved on the second slide rod 311. The second cylinder is fixed on the first mounting plate 22, and the output end of the second cylinder is connected to the second sliding member. The second sliding member is connected to the second mounting plate 32. The second slide rail 312 extends along the Y-axis and is fixed on the first mounting plate 22. The second slider is slidably disposed on the second slide rail 312 and connected to the second mounting plate 32. The second cylinder can drive the second sliding member to move along the Y-axis, and the second slider slides along the second slide rail 312, thereby guiding the second mounting plate 32 to move linearly along the Y-axis, so that the conveying and positioning device 4 can switch between an idle station and a docking station. The sliding engagement between the second slide bar 311 and the second sliding member, combined with the guiding effect of the second slide rail 312 and the second slider, ensures the stability and accuracy of the linear movement of the second mounting plate 32 along the Y-axis, enabling the conveying and positioning device 4 to quickly and accurately switch between idle and docking stations, avoiding jamming or deviation during movement, and improving station switching efficiency.

[0087] like Figures 3-4As shown, the feeding mechanism 41 includes a rotary motor 411, a rotating shaft 412, and two limiting baffles 413. The rotary motor 411 is fixed to the second mounting plate 32. The output end of the rotary motor 411 passes through the second mounting plate 32 and is connected to one end of the rotating shaft 412. The solder strip 100 is rolled into a solder tray 200 and sleeved on the other end of the rotating shaft 412. The rotary motor 411 can drive the rotating shaft 412 to rotate and drive the solder tray 200 to rotate synchronously to feed the solder. The two limiting baffles 413 are sleeved on the rotating shaft 412 and located on both sides of the solder tray 200, and respectively abut against both sides of the solder tray 200. The rotating shaft 412 is fixed with the two limiting baffles 413 by interference fit. The limiting baffles 413 are used to restrict the solder tray 200 from moving axially along the rotating shaft 412. The rotary motor 411 drives the rotating shaft 412 to stably feed the solder tray 200. Two limit baffles 413 are interference-fitted with the rotating shaft 412 and abut against both sides of the solder tray 200, effectively restricting the solder tray 200 from moving axially along the rotating shaft 412. This avoids deviation and jamming during the feeding of the solder strip 100, improves the stability and accuracy of the solder strip 100 conveying, and provides a reliable guarantee for the subsequent automatic feeding process.

[0088] like Figure 3 and Figure 5As shown, the tensioning mechanism 42 includes a first guide roller 421, a second guide roller 422, a guide rail 423, a positioning rod 424, a baffle 425, a lower sensor 426, and an upper sensor 427. Both the first guide roller 421 and the second guide roller 422 are rotatably connected to the second mounting plate 32. The guide rail 423 extends along the Z-axis and is fixed to the second mounting plate 32. The end of the positioning rod 424 is slidably disposed on the guide rail 423, with the X-axis, Y-axis, and Z-axis directions perpendicular to each other. The baffle 425 is fixed to the side of the positioning rod 424. Solder strip 100 is sequentially wound around the upper surface of the first guide roller 421, the lower surface of the positioning rod 424, and the upper surface of the first guide roller 425. The upper surface of the two guide rollers 422 is used to arrange the solder strip 100 in a U-shape. The positioning rod 424 moves upward along the guide rail 423 under the support of the solder strip 100, or moves downward along the guide rail 423 under its own gravity, so as to drive the baffle 425 to move up and down synchronously along the Z-axis. The lower sensor 426 and the upper sensor 427 are both fixed on the second mounting plate 32 and are spaced apart along the Z-axis, respectively corresponding to the lower limit movement position and the upper limit movement position of the positioning rod 424. When the upper sensor 427 senses the baffle 425, it can send a first positioning signal. When the lower sensor 426 senses the baffle 425, it can send a second positioning signal. The automatic solder feeding equipment also includes a controller. The rotary motor 411, lower sensor 426, and upper sensor 427 are all electrically connected to the controller. The controller receives the first positioning signal and controls the rotary motor 411 to drive the solder tray 200 to rotate and feed the solder. The controller receives the second positioning signal and controls the rotary motor 411 to stop. By arranging the solder strip 100 in a U-shape and using the up-and-down movement of the positioning rod 424 to drive the baffle 425 to trigger the upper sensor 427 and lower sensor 426, the controller automatically controls the rotary motor 411 to start and stop feeding the solder strip. This achieves real-time monitoring and dynamic adjustment of the solder strip 100's tension, preventing the solder strip 100 from becoming loose, shifting, or breaking due to excessive tension, ensuring conveying stability and accuracy, and providing reliable tension control for the automatic feeding process.

[0089] like Figure 3 and Figure 6As shown, the feeding mechanism 43 includes a pressing assembly 431 and a clamping assembly 432. The pressing assembly 431 includes a pressing cylinder 4311, a pressing plate 4312, and a support plate 4313. The pressing cylinder 4311 and the support plate 4313 are both fixed on the second mounting plate 32. The support plate 4313 and the pressing plate 4312 are spaced apart along the Z-axis. The support plate 4313 is used to support the solder strip 100. The pressing plate 4312 is connected to the output end of the pressing cylinder 4311. The pressing cylinder 4311 can drive the pressing plate 4312 to reciprocate along the Z-axis to press and fix or release the solder clamped between the pressing plate 4312 and the support plate 4313. The clamping assembly 432 includes an actuating cylinder 4321, an opening / closing cylinder 4322, and a gripper 4323. The actuating cylinder 4321 is fixed to the second mounting plate 32. The opening / closing cylinder 4322 is located at the output end of the actuating cylinder 4321. The gripper 4323 is located at the output end of the opening / closing cylinder 4322. The opening / closing cylinder 4322 can drive the gripper 4323 to close and clamp the solder strip 100, or to open and release the solder strip 100. The actuating cylinder 4321 can drive the opening / closing cylinder 4322 to move along the Y-axis direction, so as to drive the gripper 4323 and the solder strip 100 clamped by the gripper 4323 to be conveyed to the input end of the guide structure 44 according to a preset length. The pressing assembly 431 drives the pressing plate 4312 to press the solder strip 100 through the pressing cylinder 4311, ensuring the positioning stability before conveying. The clamping assembly 432 controls the gripper 4323 to accurately clamp or release the solder strip 100 with the help of the opening and closing cylinder 4322. The action cylinder 4321 moves along the Y-axis to realize the accurate conveying of the solder strip 100 according to the preset length, avoiding the problems of deviation and slippage during the conveying process, and improving the conveying accuracy and reliability of the solder strip 100.

[0090] like Figure 5 and Figure 6 As shown, specifically, the solder strip 100 is conveyed to the feeding mechanism 43 after passing through the tensioning mechanism 42. The pressing cylinder 4311 drives the pressing plate 4312 to move downward, cooperating with the support plate 4313 to press and fix the solder strip 100. Then, the opening and closing cylinder 4322 drives the gripper 4323 to close and hold the solder strip 100 in front of the pressing point. The pressing plate 4312 resets upward and releases the solder strip 100. The actuating cylinder 4321 drives the opening and closing cylinder 4322 to move along the Y-axis, driving the gripper 4323 and the solder strip 100 to be conveyed to the input end of the guide structure 44 according to the preset length. After the conveying is completed, the pressing plate 4312 presses and fixes the solder strip 100 again, and the gripper 4323 opens and resets, completing one feeding cycle. The feeding mechanism 43 works in concert with the pressing component 431 and the clamping component 432 to prevent the solder strip 100 from slipping or deviating during feeding, precisely control the feeding length, improve feeding accuracy, reduce manual intervention, ensure the stability of subsequent solder feeding, and provide support for the efficient operation of the welding process.

[0091] like Figure 4 and Figure 6 As shown, the clamping assembly 432 also includes a limiting rod 4324, which extends along the Y-axis. The connecting end of the limiting rod 4324 is connected to the piston rod of the actuating cylinder 4321 away from the end of the disengaging cylinder 4322. The limiting end of the limiting rod 4324 passes through the cylinder body of the actuating cylinder 4321 away from its output end and extends out. The limiting end of the limiting rod 4324 is also provided with a limiting protrusion. The limiting protrusion is used to limit the extension stroke of the piston rod along the Y-axis by abutting against the end face of the cylinder body of the actuating cylinder 4321, so as to limit the feeding length of the solder strip 100. The limiting rod 4324 abuts against the end face of the cylinder body of the actuating cylinder 4321 through the limiting protrusion, precisely limiting the extension stroke of the piston rod, thereby strictly controlling the feeding length of the solder strip 100, avoiding the impact of excessive or insufficient feeding on welding quality. In conjunction with the clamping action of the gripper 4323, the feeding accuracy is further improved, ensuring the consistency of the feeding parameters of the solder strip 100, and providing reliable support for the stability of subsequent welding processes.

[0092] It is worth noting that the actuating cylinder 4321 is a three-axis cylinder. One end of each of the three piston rods of the three-axis cylinder is connected to the opening and closing cylinder 4322, and the other end of the middle piston rod is connected to the limiting rod 4324. By using a three-axis cylinder as the actuating cylinder 4321, its three piston rods synchronously drive the opening and closing cylinder 4322 to move, effectively improving the movement stability and straightness of the opening and closing cylinder 4322 and the gripper 4323, and avoiding problems such as swaying and jamming during movement. The connection between the middle piston rod and the limiting rod 4324 ensures the synchronization of the movement of the limiting rod 4324 and the piston rod, further enhancing the precise control of the feeding length and improving the overall operational reliability of the feeding mechanism 43.

[0093] like Figure 3 and Figure 6 As shown, the guide structure 44 includes a guide plate 441, a first limiting plate 442, and a second limiting plate 443. The guide plate 441 is fixed on the second mounting plate 32. The first limiting plate 442 and the second limiting plate 443 extend along the Y-axis and are spaced apart on the guide plate 441 along the X-axis. The first limiting plate 442 and the second limiting plate 443 are clamped to form a guide groove 440. The width of the guide groove 440 is adapted to the width of the solder strip 100. The guide groove 440 can guide the solder strip 100 to be transported to the welding area along the Y-axis and restrict the solder strip 100 from deviating along the X-axis. The guide groove 440 is formed by the cooperation of the first limiting plate 442 and the second limiting plate 443. Its clamping width is adapted to the solder strip 100, which can accurately guide the solder strip 100 to be stably transported to the welding area along the Y-axis direction, while effectively limiting the solder strip 100 to deviate along the X-axis direction, avoiding positional deviation of the solder strip 100 at the end of the transport, ensuring the alignment accuracy of the solder strip 100 and the welding area, and providing support for the high-quality completion of subsequent welding processes.

[0094] like Figure 7 As shown, the cutting mechanism 53 includes a third mounting plate 531, a lower cutter 532, a cutting cylinder 533, a connecting seat 534, and an upper cutter 535. The third mounting plate 531 is disposed at the output end of the fourth drive mechanism 52, and the lower cutter 532 is fixedly mounted on the third mounting plate 531. The cutting cylinder 533 is fixedly connected to the third mounting plate 531, and the output end of the cutting cylinder 533 is connected to the upper cutter 535 through the connecting seat 534. The cutting edges of the upper cutter 535 and the lower cutter 532 are aligned vertically. The cutting cylinder 533 can drive the upper cutter 535 to move along the Z-axis direction, and work together with the lower cutter 532 to cut the solder strip 100 sandwiched between the two. The upper cutter 535 and the lower cutter 532 are precisely aligned. The cutting cylinder 533 drives the upper cutter 535 to move along the Z-axis, working in conjunction with the lower cutter 532 to quickly cut the solder strip 100. The cut is smooth and burr-free, avoiding the impact of incomplete cutting or cut deformation on subsequent welding processes. At the same time, the cutting action is responsive and can be accurately matched with the automatic feeding rhythm, improving the overall automation efficiency of the automatic solder feeding equipment.

[0095] like Figure 7 As shown, the third drive mechanism 51 includes a mounting platform 510, a third motor, a third lead screw 511, a third nut, a third slide rail 512, and a third slider 513. The third motor is fixed to the first mounting plate 22. The third lead screw 511 extends along the Y-axis and is connected to the output end of the third motor. The third lead screw 511 is threaded through the third nut, which is connected to the mounting platform 510. The fourth drive mechanism 52 is mounted on the mounting platform 510. The third slide rail 512 extends along the Y-axis and is fixed to the first mounting plate 22. The third slider 513 is slidably mounted on the third slide rail 512 and connected to the mounting platform 510. The third motor can drive the third lead screw 511 to rotate, causing the third nut to move along the Y-axis. The third slider 513 slides synchronously along the third slide rail 512, thereby guiding the mounting platform 510 and the fourth drive mechanism 52 to move linearly along the Y-axis, so that the position of the cutting mechanism 53 in the Y-axis direction is adjustable, thereby adjusting the cutting length of the subsequent solder strip 100. The threaded transmission of the third lead screw 511 and the third nut, together with the guide limit of the third slide rail 512 and the third slider 513, drives the mounting table 510 and the fourth drive mechanism 52 to move in a high-precision linear motion along the Y-axis, thereby realizing the precise adjustment of the Y-axis position of the cutting mechanism 53, and thus flexibly adjusting the cutting length of the solder strip 100 to adapt to the material requirements of different welding scenarios, and improving the versatility and cutting accuracy of the automatic solder feeding equipment.

[0096] like Figure 7As shown, the fourth drive mechanism 52 includes a fourth slide rod, a fourth sliding member, a fourth cylinder 521, a fourth slide rail 522, and a fourth slider. The fourth slide rod extends along the X-axis and is fixed on the mounting platform 510. The fourth sliding member is slidably sleeved on the fourth slide rod. The fourth cylinder 521 is fixed on the mounting platform 510. The output end of the fourth cylinder 521 is connected to the fourth sliding member. The fourth sliding member is connected to the third mounting plate 531. The fourth slide rail 522 extends along the X-axis and is fixed on the mounting platform 510. The fourth slider is slidably disposed on the fourth slide rail 522 and connected to the third mounting plate 531. The fourth cylinder 521 can drive the fourth sliding member to move along the X-axis, and the fourth slider slides along the fourth slide rail 522, thereby guiding the third mounting plate 531 to move linearly along the X-axis, so that the cutting mechanism 53 switches between the avoidance station and the cutting station. The dual guidance of the fourth slide bar and the fourth slide rail 522 ensures the stability and accuracy of the linear movement of the third mounting plate 531 along the X-axis, driving the cutting mechanism 53 to quickly and accurately switch between the avoidance station and the cutting station. During cutting, the solder strip 100 is precisely aligned, and during avoidance, the conveying path of the solder strip 100 is not interfered with, improving the coordination between the cutting action and the feeding process, and ensuring the smooth operation of the automatic welding solder feeding equipment.
