Abstract
Description
Technical Field
[0001] This invention relates to the field of welding equipment technology, and in particular to a welding equipment for the production of fishing gear accessories. Background Technology
[0002] Fishing tackle accessories include a wide variety of guide rings, typically consisting of a sleeve and a line guide ring. During production, the line guide ring needs to be installed on the end of the sleeve and welded in place. With increasing demands for automated production, related welding processes are gradually shifting from manual operation to automated feeding, positioning, and welding.
[0003] However, in actual production, the guide ring is usually an irregular structure, with its contacts angled relative to the ring body. Furthermore, the contacts may vary in length, angle, and feeding posture between different batches or workpieces. Thus, during automatic feeding and welding, if only fixed-track conveying, fixed-position docking, or fixed-stroke advancement methods are used, the contacts of the guide ring often struggle to form a stable and accurate overlap with the end of the sleeve. This can easily lead to situations such as failure to contact, insufficient contact, excessive slippage, or even exceeding the end of the sleeve, resulting in problems like incomplete welding, missed welding, or misaligned welding.
[0004] Existing automated welding equipment typically focuses on detecting whether the workpiece has reached the predetermined station, or determining whether parts are in contact through vision or limiting methods. However, for parts like the wire guide ring, which have irregular structures and whose contacts are susceptible to dimensional and orientation errors, simply determining whether contact or position is sufficient often fails to accurately reflect whether a suitable lap joint has been formed with the end of the sleeve. Especially with a fixed push-out distance, if the contact length is too long or the angle is abnormal, although the contact may make contact with the end of the sleeve, it may continue to slide along the end surface during further push-out, eventually exceeding the predetermined lap joint position and affecting the welding quality.
[0005] Therefore, when existing welding equipment automatically feeds and welds the wire guide ring and the sleeve, the irregular structure of the wire guide ring makes it difficult to position, and the contact feet have angular and length errors, which easily leads to inaccurate overlap between the contact feet and the end of the sleeve, resulting in problems such as incomplete welding, missing welding, or misaligned welding, which urgently need to be solved. Summary of the Invention
[0006] The purpose of this invention is to solve the problems in the prior art where the irregular structure of the line guide ring makes it difficult to position, and the contact feet have angular and length errors, which easily lead to inaccurate overlap between the contact feet and the end of the sleeve, resulting in incomplete welding, missing welding, or misaligned welding. Therefore, this invention proposes a welding equipment for the production of fishing gear accessories.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a welding equipment for producing fishing gear accessories, comprising: The frame on which the reference plate and servo motor are fixedly mounted; A laser welding assembly, mounted on the frame, is used to weld the sleeve and line guide ring of fishing gear accessories; A rotating disk is rotatably mounted on the frame. The servo motor drives the rotating disk to rotate in increments. The rotating disk is provided with a clamp for holding the sleeve part and making the sleeve part rotate with the rotating disk. A floating top rod is provided inside the clamp. The floating top rod is used to be pressed down when the wire loop part presses against the sleeve part. A wire guide ring conveying and adjusting assembly is mounted on the frame and is used to output the wire guide ring in the horizontal direction. The wire guide ring has a contact foot that is set at a preset angle with the ring body. A non-contact displacement sensor is mounted on the reference plate and cooperates with the floating top rod to detect the displacement of the floating top rod. When the rotating disk rotates to a preset welding angle, the sleeve part is tilted relative to the output direction of the wire guide ring part, so that when the wire guide ring part outputs, its contact foot contacts the end of the sleeve part and slides along the end surface of the sleeve part and presses down, so that the floating top rod generates a corresponding displacement. The wire guide ring conveying adjustment assembly adjusts the output of the wire guide ring according to the displacement, so that the contact foot and the end of the sleeve form a preset overlap position, and the laser welding assembly welds the preset overlap position.
[0008] Preferably, the wire guide ring conveying adjustment assembly includes a fixed guide rail fixedly mounted on the frame, a telescopic guide rail slidably mounted on the output end of the fixed guide rail, and a servo electric cylinder for driving the telescopic guide rail to move. The fixed guide rail and the telescopic guide rail are used to guide and convey the wire guide ring.
[0009] Preferably, a first return spring is provided between the fixed guide rail and the telescopic guide rail, and an elastic pressing plate is connected to the telescopic end of the servo electric cylinder, the end of which extends into the telescopic guide rail; when the servo electric cylinder telescopically moves, it drives the elastic pressing plate to push the telescopic guide rail to move and press the wire guide ring to push the wire guide ring to output in the horizontal direction.
[0010] The elastic clamping sheet has a limiting protrusion at its end that clamps the threaded loop, and the upper side of the telescopic guide rail is threaded with an adjusting bolt for constraining the elastic clamping sheet.
[0011] Preferably, the clamp includes a fixed clamping block and a movable clamping block, the movable clamping block being slidably connected to the fixed clamping block, and a clamping cavity for clamping the sleeve portion being formed between the fixed clamping block and the movable clamping block. A support spring is sleeved on the surface of the floating top rod, and the floating top rod is movably disposed within the clamping cavity. A rubber roller is rotatably mounted on the side of the movable clamping block near the reference plate. A second return spring is provided in the rotating plate for applying an elastic force to the mounting support of the rubber roller. Under the action of the second return spring, the rubber roller rolls in cooperation with the end face of the reference plate, thereby driving the movable clamping block to move relative to the fixed clamping block during the rotation of the rotating plate, thereby opening or clamping the clamp.
[0012] Preferably, the end face of the reference plate is provided with a clearance groove. When the roller rolls into the clearance groove, the movable clamping block moves away from the fixed clamping block so that the clamp opens and allows the sleeve to enter or leave the clamp. When the roller rolls out of the clearance groove, the movable clamping block moves toward the fixed clamping block so that the clamp clamps the sleeve.
[0013] Preferably, two trigger blocks are slidably arranged inside the reference plate, and an electromagnetic driver is provided on the frame to drive the action of each trigger block. The electromagnetic driver drives the corresponding trigger block to retract, so as to form an additional clearance position on the end face of the reference plate for the roller to roll in, thereby releasing the corresponding clamp. A first collection groove and a second collection groove are respectively provided on the frame at different release positions, so as to control the clamp to release the product at different release positions through the corresponding trigger blocks.
[0014] Preferably, the frame is equipped with a first detection camera and a second detection camera. The first detection camera is used to detect the initial docking state between the contact foot of the wire guide ring and the end of the sleeve. The non-contact displacement sensor is used to detect the displacement of the floating top rod and control the output of the wire guide ring conveying adjustment assembly to adjust the output of the wire guide ring so that the contact foot and the end of the sleeve form a preset overlap position. The second detection camera is used to detect the welding quality at the welding point and control the product to enter the first collection tank or the second collection tank according to the detection result.
[0015] Preferably, the frame is provided with a first vibratory plate and a second vibratory plate. The first vibratory plate is used to transport the sleeve part to the clamp, and the second vibratory plate is used to transport the wire guide ring part to the wire guide ring transport adjustment assembly.
[0016] Preferably, when the non-contact displacement sensor detects that the displacement of the floating top rod has not reached the preset range, the wire ring conveying adjustment assembly continues to push the current wire ring output so that the contact foot continues to slide and press down along the end surface of the sleeve. When the displacement reaches a preset range, the wire ring conveying adjustment component is controlled to stop output, so that the contact foot and the end of the sleeve form a preset overlap position, and the laser welding component is controlled to perform welding. When the displacement exceeds the preset range, or fails to reach the preset range within the preset output stroke, it is determined that the current wire guide ring does not meet the welding conditions, and the wire guide ring conveying adjustment component is controlled to remove the current wire guide ring from the welding position and convey the next wire guide ring.
[0017] The present invention has the following beneficial effects: 1. This invention tilts the sleeve section relative to the output direction of the wire guide ring at the welding station, and makes the wire guide ring output horizontally. This allows the contact of the wire guide ring to slide and press down along the end surface of the sleeve section when it approaches the end of the sleeve section. Since the contact generates a corresponding downward displacement during the accurate overlap process, this displacement is detected by a floating top rod and a non-contact displacement sensor. This converts the actual overlap state between the contact and the end of the sleeve section into a quantifiable displacement signal, thereby determining whether the current wire guide ring meets the welding requirements. This not only compensates for positioning errors generated during automatic feeding of the wire guide ring, but also adaptively adjusts for dimensional or posture errors such as inconsistent contact lengths and angles, avoiding problems such as incomplete, insufficient, or excessively slipping contact, leading to weak welds, missed welds, or misaligned welds.
[0018] 2. In this invention, the wire guide ring conveying adjustment component does not use a fixed output stroke to push the wire guide ring to complete the docking. Instead, it adjusts the output of the wire guide ring based on the displacement detected by a non-contact displacement sensor, and stops outputting when the displacement reaches a preset range, allowing the contact to stop at a preset overlap position with the end of the sleeve. This avoids the problem of welding position deviation caused by the contact length being too long or the angle being abnormal, allowing it to continue sliding beyond the end of the sleeve at a fixed pushing distance, thus improving the consistency of the welding position and the stability of the welding quality.
[0019] 3. In this invention, when the non-contact displacement sensor detects that the displacement of the floating top rod does not reach or exceeds the preset range, it can be determined that the current wire guide ring does not meet the welding conditions, and the wire guide ring conveying adjustment component is controlled to remove the current wire guide ring from the welding position and convey the next wire guide ring. In this way, the identification and rejection of unqualified workpieces are completed before welding, reducing the number of defective products entering the welding process and improving the continuity, reliability and product yield of automatic welding.
[0020] 4. In this invention, the fixture rotates with the rotating disk, sequentially passing through the loading station, welding station, inspection station, and release station. Automatic loading of the sleeve section and the wire guide ring section is achieved through the first and second vibrating disks, respectively. Automatic welding is completed through the laser welding assembly. The first and second inspection cameras respectively detect the pre-welding docking status and post-welding welding quality. Furthermore, the trigger block, electromagnetic driver, first collection trough, and second collection trough enable the classified release of products. Thus, the entire device possesses the functions of automatic loading, automatic indexing and transfer, automatic welding, automatic inspection, and automatic sorting of qualified and unqualified products. This reduces manual intervention, improves production efficiency, inspection reliability, and product sorting accuracy, further enhancing the overall automation level and production stability of the equipment.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0036] Example 1 refer to Figures 1-12This embodiment proposes a welding equipment for producing fishing gear accessories, including a frame 100. A reference plate 101 and a servo motor 102 are fixedly mounted on the frame 100. A laser welding assembly 103 and a non-contact displacement sensor 104 are also provided on the frame 100. The laser welding assembly 103 includes a laser generator and a laser welding head. The laser welding head is used to perform laser welding on the overlapping position of the contact foot 503 and the end of the sleeve part 501. A rotating disk 200 is rotatably mounted on the frame 100. The servo motor 102 is used to drive the rotating disk 200 to perform indexing rotation. Multiple clamps 202 are provided on the rotating disk 200. Each clamp 202 is used to clamp the sleeve part 501 and make the sleeve part 501 rotate synchronously with the rotating disk 200.
[0037] like Figure 5 , Figure 6 As shown, a floating top rod 201 is provided inside the clamp 202. The floating top rod 201 can be movably disposed inside the clamp 202 in the vertical direction. When the wire loop portion 502 presses against the sleeve portion 501, the floating top rod 201 can be pressed down. A non-contact displacement sensor 104 is disposed on the reference plate 101 and cooperates with the floating top rod 201 to detect the displacement of the floating top rod 201.
[0038] like Figure 10 As shown, a wire ring conveying adjustment assembly 300 is provided on the frame 100. The wire ring conveying adjustment assembly 300 is used to output the wire ring portion 502 in the horizontal direction. The wire ring portion 502 has a contact foot 503 set at a preset angle with the ring body. When the rotary table 200 rotates to the welding station, the sleeve portion 501 held by the clamp 202 is inclined relative to the output direction of the wire ring portion 502, so that during the output process, the contact foot 503 of the wire ring portion 502 approaches the end of the sleeve portion 501.
[0039] In this embodiment, the wire loop portion 502 does not directly and rigidly abut against the sleeve portion 501. Instead, during the output process, the contact foot 503 first contacts the end of the sleeve portion 501 and slides and presses down along the end surface of the sleeve portion 501. Due to length errors, angle errors, or feeding posture errors of the contact foot 503, when the contact foot 503 and the end of the sleeve portion 501 form an accurate overlap, the downward pressure generated by the contact foot 503 is within a relatively stable range, and the floating top rod 201 generates a corresponding displacement. The non-contact displacement sensor 104 can determine whether the contact foot 503 and the end of the sleeve portion 501 have reached a preset overlap state by detecting this displacement.
[0040] Furthermore, the wire ring conveying adjustment assembly 300 adjusts the output of the wire ring section 502 according to the displacement detected by the non-contact displacement sensor 104. When the displacement does not reach the preset range, the wire ring conveying adjustment assembly 300 continues to push the wire ring section 502 to output, so that the contact 503 continues to slide and press down along the end surface of the sleeve section 501; when the displacement reaches the preset range, the wire ring conveying adjustment assembly 300 stops outputting. At this time, the contact 503 and the end of the sleeve section 501 form a preset overlap position, and then the laser welding assembly 103 welds the contact 503 and the end of the sleeve section 501.
[0041] When the non-contact displacement sensor 104 detects that the displacement of the floating top rod 201 exceeds the preset range, or fails to reach the preset range within the preset output stroke, it is determined that the current wire guide ring 502 does not meet the welding conditions. In this case, the control wire guide ring conveying adjustment assembly 300 removes the current wire guide ring 502 from the welding position and conveys the next wire guide ring 502 to avoid incomplete welding, missed welding, or misaligned welding caused by abnormal length, angle, or positioning of the contact foot 503.
[0042] With the above structural configuration, in this embodiment, when the rotating disk 200 rotates to the preset welding angle ∠A, the inclined arrangement of the sleeve part 501, the horizontal output of the wire loop part 502, and the sliding and pressing relationship of the contact foot 503 along the end surface of the sleeve part 501 convert the accurate overlapping state into a detectable displacement amount. This displacement amount is used as the criterion for the wire loop part 502 to stop output and perform welding, thereby improving welding accuracy and welding stability.
[0043] Example 2 Based on Example 1, this example further explains the specific structure of the wire loop conveying adjustment assembly 300.
[0044] like Figure 8 As shown, the wire guide ring conveying adjustment assembly 300 includes a fixed guide rail 301 fixedly mounted on the frame 100, a telescopic guide rail 302 slidably mounted on the output end of the fixed guide rail 301, and a servo electric cylinder 303 for driving the telescopic guide rail 302 to move. A first return spring 304 is provided between the fixed guide rail 301 and the telescopic guide rail 302. The fixed guide rail 301 and the telescopic guide rail 302 together form the guiding conveying channel of the wire guide ring 502, so that the wire guide ring 502 can be stably output to the welding station in a preset direction.
[0045] Specifically, such as Figure 9 , Figure 10As shown, the telescopic end of the servo electric cylinder 303 is connected to an elastic clamping plate 305, the end of which extends into the telescopic guide rail 302. The end of the elastic clamping plate 305 is provided with a limiting protrusion 306 for clamping the wire loop portion 502. Figure 11 As shown, an adjusting bolt 307 is threaded on the upper side of the telescopic guide rail 302. The adjusting bolt 307 is used to limit and constrain the elastic pressing plate 305 to adjust the pressing force and pressing height of the elastic pressing plate 305 on the wire loop 502.
[0046] At work, such as Figure 10 As shown, the wire guide ring 502 is arranged and moves forward under the guidance of the fixed guide rail 301 and the telescopic guide rail 302. When the servo electric cylinder 303 extends, it drives the elastic pressing plate 305 to move forward. The elastic pressing plate 305 presses the wire guide ring 502 under the action of the limiting protrusion 306, and relies on its supporting action and pushing force in the output direction to push the telescopic guide rail 302 and the wire guide ring 502 to output horizontally towards the welding station. Figure 11 As shown, when the servo electric cylinder 303 retracts, the first reset spring 304 drives the telescopic guide rail 302 to reset, that is, the telescopic guide rail 302 moves away from the rotating disk 200, so as to provide clearance space for the rotation of the rotating disk 200 and facilitate the conveying of the next wire loop part 502.
[0047] Because the elastic clamping plate 305 provides elastic compression to the wire guide ring 502, during the output process of pushing the wire guide ring 502, not only can the wire guide ring 502 be prevented from jumping or deflecting within the guide rail, but the output can also be precisely adjusted by the servo electric cylinder 303 after the non-contact displacement sensor 104 provides feedback on the displacement information. Thus, the output process of the wire guide ring 502 is no longer limited to a fixed stroke, but can be dynamically adjusted according to the actual overlap state, thereby providing a stable conveying foundation for the contact foot 503 to slide along the end surface of the sleeve portion 501 and accurately overlap.
[0048] It should be noted that, as Figure 8 and Figure 9 As shown, the conveying channel within the telescopic guide rail 302 only provides coarse positioning for the output orientation of the contact foot 503. The accurate determination of the overlap position does not depend on the conveying channel itself, but rather on the displacement formed by the sliding and pressing action of the contact foot 503 after contacting the end of the sleeve portion 501. Therefore, when the current wire-passing ring portion 502 cannot form a preset displacement range, it is determined that it does not meet the welding conditions, and the current wire-passing ring portion 502 is withdrawn before the next wire-passing ring portion 502 is conveyed. The relevant detection and control logic is described in detail in Embodiment 4.
[0049] Example 3 Based on Example 1, this example further explains the cooperation structure of the clamp 202, the floating top rod 201 and the reference plate 101.
[0050] Specifically, such as Figure 7 As shown, the clamp 202 includes a fixed clamping block 203 and a movable clamping block 204. The fixed clamping block 203 is fixedly mounted on the rotating disk 200, and the movable clamping block 204 is slidably connected to the fixed clamping block 203. A clamping cavity for clamping the sleeve portion 501 is formed between the fixed clamping block 203 and the movable clamping block 204. The floating top rod 201 is movably disposed in the clamping cavity, and a support spring 205 is sleeved on the surface of the floating top rod 201. The support spring 205 provides an upward supporting force to the floating top rod 201 so that the floating top rod 201 maintains its initial position when not under pressure.
[0051] like Figure 6 , Figure 7 As shown, a rubber roller 206 is rotatably mounted on the side of the movable clamping block 204 near the reference disk 101. A second return spring 207 is provided inside the rotating disk 200. The second return spring 207 is used to apply an elastic force to the mounting support of the rubber roller 206, so that the rubber roller 206 is always pressed against the end face of the reference disk 101. Figure 5 As shown, the end face of the reference plate 101 is provided with a clearance groove 105. When the rubber roller 206 rolls into the clearance groove 105, the movable clamping block 204 moves away from the fixed clamping block 203 under the action of the second return spring 207 and the change in the contour of the reference plate 101, thereby opening the clamp 202. When the rubber roller 206 rolls out of the clearance groove 105, the movable clamping block 204 moves toward the fixed clamping block 203, thereby clamping the sleeve part 501 with the clamp 202. It should be noted that the clamping of the sleeve part 501 by the clamp 202 is not a rigid lock. The clamping force is determined by the pressure between the rubber roller 206 and the end face of the reference plate 101 and the elastic force provided by the second return spring 207. This allows the sleeve part 501 to move synchronously with the clamp 202 when it is clamped, and it can also slide axially relative to the clamp 202 when it is pressed by the contact foot 503 of the wire loop part 502. In this way, when the contact foot 503 contacts the end of the sleeve part 501 and continues to slide and press down, the sleeve part 501 can be pressed and moved within the clamp 202, and drive the floating top rod 201 to move down, thereby facilitating the non-contact displacement sensor 104 to detect the displacement of the floating top rod 201.
[0052] In this embodiment, as Figure 2As shown, the sleeve portion 501 is conveyed to the loading position of the clamp 202. When the rubber roller 206 rolls into the clearance groove 105, the clamp 202 is in the open state, and the sleeve portion 501 enters the clamping cavity; as the rotating disk 200 continues to rotate, the rubber roller 206 rolls out of the clearance groove 105, the movable clamping block 204 moves closer to the fixed clamping block 203, the sleeve portion 501 is clamped and transported together with the clamp 202.
[0053] like Figure 10 As shown, when the clamp 202 rotates the sleeve portion 501 to the welding position, the wire guide ring portion 502 is pushed towards the sleeve portion 501 by the wire guide ring conveying adjustment assembly 300. Its contact foot 503 contacts the end of the sleeve portion 501 and slides and presses down along the end surface. Since the floating top rod 201 is located in the clamping cavity and forms a force transmission relationship with the sleeve portion 501, the pressing action of the contact foot 503 on the sleeve portion 501 is transmitted to the floating top rod 201, causing the floating top rod 201 to move downward against the elastic force of the support spring 205. The non-contact displacement sensor 104 can thus detect the displacement of the floating top rod 201.
[0054] With the above-mentioned structural configuration, the clamp 202 can not only automatically clamp the sleeve part 501 and index and transfer it with the rotating disk 200, but also convert the overlapping and pressing state of the contact foot 503 and the end of the sleeve part 501 into a detectable displacement change through the floating top rod 201, providing a reliable basis for the overlapping judgment before welding.
[0055] Example 4 Based on Example 1, this example further explains the detection and control logic of the non-contact displacement sensor 104, the first detection camera 111, and the second detection camera 112.
[0056] Specifically, such as Figure 2 As shown, the first inspection camera 111 is located near the welding station, preferably on the lower surface of the laser welding head of the laser welding assembly 103, and is used to detect the mating status between the contact 503 of the wire loop portion 502 and the end of the sleeve portion 501; the second inspection camera 112 is located at the post-weld inspection station and is used to detect the welding quality at the weld. Figure 5 As shown, a non-contact displacement sensor 104 is mounted on a reference plate 101 and cooperates with a floating top rod 201 to detect the displacement of the floating top rod 201 in real time.
[0057] In this embodiment, the first detection camera 111 can first identify the initial docking state between the wire loop portion 502 and the sleeve portion 501 to determine whether the contact foot 503 is approaching the end of the sleeve portion 501, or whether there is any obvious abnormal posture or misalignment; when the initial docking state meets the requirements, such as Figure 10As shown, the servo electric cylinder 303 pushes the wire loop part 502 to continue outputting, so that the contact foot 503 contacts the end of the sleeve part 501 and slides and presses down along the end surface. The non-contact displacement sensor 104 synchronously detects the displacement change of the floating top rod 201.
[0058] When the non-contact displacement sensor 104 detects that the displacement of the floating top rod 201 has not reached the preset range, it indicates that the contact foot 503 has not yet formed an accurate overlap with the end of the sleeve part 501, or the current pressure is insufficient. At this time, the control wire ring conveying adjustment component 300 continues to push the current wire ring part 502 output, so that the contact foot 503 continues to slide and press down along the end surface of the sleeve part 501, thereby fine-tuning the overlap position between the contact foot 503 and the end of the sleeve part 501.
[0059] When the non-contact displacement sensor 104 detects that the displacement of the floating top rod 201 has reached a preset range, it indicates that the contact foot 503 has slid to the preset overlap position with the end of the sleeve portion 501. At this time, the control wire ring conveying adjustment component 300 stops output and the control laser welding component 103 welds the contact foot 503 to the end of the sleeve portion 501. Therefore, the output endpoint of the servo electric cylinder 303 is not fixed, but is determined by the displacement corresponding to the contact foot 503 forming an accurate overlap state.
[0060] When the non-contact displacement sensor 104 detects that the displacement of the floating top rod 201 exceeds the preset range, it indicates that the contact foot 503 is abnormally pressed against the end of the sleeve part 501, which may be due to the contact foot 503 being too long, having an abnormal angle, or excessive slippage. Alternatively, if the displacement of the floating top rod 201 does not reach the preset range within the preset output stroke, it indicates that the contact foot 503 may not be in effective contact with the end of the sleeve part 501, or that the current feeding posture of the wire loop part 502 is abnormal. (This situation is referred to...) Figure 12 In both of the above situations, it can be determined that the current wire guide ring 502 does not meet the welding conditions, and the wire guide ring conveying adjustment component 300 is controlled to remove the current wire guide ring 502 from the welding position before conveying the next wire guide ring 502, so as to avoid unqualified workpieces from entering the welding process.
[0061] It should be noted that the preset range of displacement detected by the non-contact displacement sensor 104 can be pre-calibrated based on the specifications of the product to be welded and the results of trial welding. Specifically, a sample with accurate overlap between the contact 503 and the end of the sleeve 501 and qualified welding quality can be selected as a calibration sample. The displacement of the floating top rod 201 in this state is detected, and the corresponding displacement window range is determined by combining the results of multiple repeated detections. This serves as the basis for judging whether the contact 503 and the end of the sleeve 501 have reached the preset overlap state during subsequent automatic welding. The preset range is preferably the upper and lower limit window range of the displacement. When the detected displacement is less than the preset lower limit, it is determined that the contact 503 and the end of the sleeve 501 have not formed an effective overlap; when the detected displacement is greater than the preset upper limit, it is determined that the contact 503 is abnormally pressed or excessively slipped; when the detected displacement is within the preset range, it is determined that the current contact 503 and the end of the sleeve 501 have met the welding requirements.
[0062] With the above settings, this embodiment can detect the overlap state of the contact 503 and the end of the sleeve 501 before welding, in cooperation with the first detection camera 111 and the non-contact displacement sensor 104, and adjust the output of the wire loop 502 in combination with displacement feedback to achieve fine adjustment and accurate positioning of the overlap position; after welding is completed, the second detection camera 112 will detect the welding quality, thereby improving the reliability, welding accuracy and product yield of the whole machine welding process.
[0063] Example 5 Based on Examples 1 to 4, this example further explains the automatic feeding, indexing and transfer, welding, inspection and sorting process of the whole machine.
[0064] Specifically, such as Figure 1 , Figure 3 As shown, a first vibratory feeder 401 and a second vibratory feeder 402 are provided on the frame 100. The first vibratory feeder 401 is used to convey the sleeve portion 501 to the loading position of the clamp 202, and the second vibratory feeder 402 is used to convey the wire guide ring portion 502 to the wire guide ring conveying adjustment assembly 300. A first collection trough 109 and a second collection trough 110 are respectively provided on the frame 100 at different release positions. Figure 5 , Figure 6 As shown, two trigger blocks 107 are slidably disposed inside the reference disk 101, and an electromagnetic driver 108 is disposed on the frame 100 to drive the action of each trigger block 107 respectively.
[0065] During operation, the first vibratory feeder 401 sequentially transports the sleeve portion 501 to the loading station of the clamp 202. After the clamp 202 opens, it receives the sleeve portion 501 into the clamping cavity and clamps the sleeve portion 501 as the rotating feeder 200 continues to rotate. Subsequently, the clamp 202 rotates indexed along with the rotating feeder 200 under the drive of the servo motor 102, causing the sleeve portion 501 to sequentially pass through the loading station, welding station, inspection station, and release station.
[0066] When the fixture 202 rotates to the welding station, the second vibratory feeder 402 conveys the wire guide ring 502 to the wire guide ring conveying adjustment assembly 300. The wire guide ring conveying adjustment assembly 300 pushes the wire guide ring 502 horizontally toward the sleeve section 501. At this time, since the sleeve section 501 is tilted relative to the output direction of the wire guide ring 502, the contact foot 503 slides along its end surface and presses down after contacting the end of the sleeve section 501. The non-contact displacement sensor 104 determines whether the contact foot 503 and the end of the sleeve section 501 have reached a preset overlap state based on the displacement of the floating top rod 201. When the displacement reaches the preset range, the wire guide ring conveying adjustment assembly 300 is controlled to stop output, and the laser welding assembly 103 is controlled to perform welding. When the displacement is abnormal, the current wire guide ring 502 is removed from the welding position, and the next wire guide ring 502 is conveyed.
[0067] After welding is completed, such as Figure 11 As shown, when the servo electric cylinder 303 retracts, the first reset spring 304 drives the telescopic guide rail 302 to reset, that is, the telescopic guide rail 302 moves away from the rotating disk 200, and the clamp 202 continues to rotate with the rotating disk 200 to the inspection station, where the second inspection camera 112 inspects the welding quality. If the inspection result shows that the product welding is qualified, at the corresponding release station, the corresponding electromagnetic driver 108 drives the corresponding trigger block 107 to retract, so as to form an additional clearance position on the end face of the reference disk 101 for the rubber roller 206 to roll into, so that the corresponding clamp 202 is released and the product is released into the first collection tank 109; if the inspection result shows that the product welding is unqualified, the electromagnetic driver 108 at another release station is controlled to drive the corresponding trigger block 107 to move, so that the clamp 202 is released at the corresponding station and the product is released into the second collection tank 110. In this way, qualified and unqualified products are classified and collected.
[0068] Through the above process settings, in this embodiment, the clamp 202 rotates indexedly with the rotating disk 200 under the drive of the servo motor 102, and passes through the loading station, welding station, inspection station and release station in sequence, thereby realizing the continuous transfer of the sleeve part 501 between each station; the first vibrating disk 401 and the second vibrating disk 402 realize the automatic loading of the sleeve part 501 and the wire ring part 502 respectively; the laser welding assembly 103 completes the automatic welding; and the first detection camera 111 and the second detection camera 112 detect the pre-welding docking status and the post-welding welding quality respectively. In addition, the trigger block 107, the electromagnetic driver 108, the first collection tank 109 and the second collection tank 110 realize the classification and release of products, so that the whole device has the functions of automatic loading, automatic indexing and transfer, automatic welding, automatic inspection and automatic sorting of qualified and unqualified products, reducing manual intervention, improving production efficiency, inspection reliability and product sorting accuracy, and further improving the overall automation level and production stability of the equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
