Description

Technical Field

[0001] This utility model relates to the field of hoop welding equipment, and specifically to a hoop laser welding system. Background Technology

[0002] In industrial manufacturing, automotive, and municipal industries, clamps are crucial devices for connecting and securing cylindrical objects such as pipes and hoses. The clamp seat, as the core component of the clamp, directly determines the clamp's tightening effect, sealing performance, and service life through its welding quality. With increasing reliability requirements in clamp applications, a new type of clamp seat has emerged—this type of clamp seat features a seamed structure (such as…). Figure 1 As shown, the weld seam is intentionally offset from the bottom centerline to avoid stress cracking caused by overlapping weld points during subsequent welding with the hoop band, thus ensuring safe use. The hoop laser welding system, as the core equipment for forming the weld seam of the new hoop, directly affects the production quality and application promotion of the new hoop due to its adaptability and welding precision.

[0003] Currently, most laser welding systems for hoop seats in the industry are designed for traditional one-piece seamless hoop seats or conventional center-seam hoop seats. When these systems are applied to weld the seam hoop seats developed by the applicant, the following problems arise: First, the positioning adaptability is poor. The positioning mechanism of the existing system cannot stably clamp the new hoop seat with the weld seam off the center line, which easily leads to hoop seat displacement, resulting in weld seam position deviation and affecting the subsequent assembly accuracy of the hoop seat and hoop band. Second, the welding accuracy is insufficient. The laser welding head cannot accurately match the offset weld seam trajectory of the new hoop seat, which easily leads to problems such as weld deviation and missed welds, resulting in substandard weld seam strength and failing to guarantee the safety of the new hoop seat, thus restricting the large-scale production and market application of the new hoop seat.

[0004] In view of this, this solution provides a laser welding system for clamp seats, which not only effectively makes up for the shortcomings of existing technologies, but also improves the welding efficiency of clamp seats and ensures the quality of the welded clamp seats, which is of great significance for ensuring the production efficiency and quality of clamps. Utility Model Content

[0005] The present invention aims to provide a laser welding system for hoop seats to solve the technical problem of the lack of a laser welding system for producing novel welded hoop seats in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser welding system for clamps, comprising a feeding and sorting unit, a transfer unit, a welding unit, and a control unit; the welding unit comprises a welding tank, a welding robot, and an unloading assembly; the control unit comprises a vibration controller, a transfer controller, and a welding robot control device; The feeding and sorting unit includes a vibratory plate and a sorting trough. The vibratory plate includes a plate body and a first vibrator. A second vibrator is provided at the bottom of the sorting trough. A full load sensor is provided at the entrance of the sorting trough. The first vibrator, the second vibrator, and the full load sensor are all electrically connected to the vibration controller.

[0007] The principles and advantages of this scheme are: 1. This solution simplifies the control logic of the welding system by continuously setting up feeding and sorting units, transfer units, and welding units, and setting up corresponding controllers / control devices for individual control at each stage. On the one hand, it facilitates the orderly and continuous sorting and feeding of the randomly scattered hoop seats in the vibratory feeder, transferring them to the welding tank, and laser welding them, thereby obtaining welded hoop seats that can be directly used for hoop assembly after passing the hammering test. On the other hand, independent control of each stage also reduces the control difficulty of the welding system. There is no need to preset complex control logic; the welding purpose can be achieved simply by the reasonable spatial arrangement between mechanical equipment, effectively reducing the cost of system equipment and improving production efficiency.

[0008] 2. This solution sets up a full-load sensor at the entrance of the sorting slot. The control unit controls the opening and closing of the first vibration transducer based on the signal from the full-load sensor, thereby controlling the sorting and feeding amount in real time. On the one hand, it effectively balances the supply of feeding amount and energy saving, achieving a balance between continuous production and energy saving and cost reduction. On the other hand, it can also control the feeding situation in real time, reduce the risk of feeding interruption, and ensure production continuity.

[0014] Technical effect: The above-mentioned settings in this solution facilitate the limitation of the movement range of the push-pull component, and at the same time, further prevent the hoop from jumping up and down and changing position when it is vibrated and transferred to the transfer groove.

[0018] Technical effect: The above-mentioned settings in this solution facilitate the buffering and collection of the unloading hoop.

[0019] Preferably, as an improvement, the welding groove is provided with a limiting tongue, the external shape of which is adapted to the contour of the inner cavity of the hoop seat, and the unloading plate is adapted to the curvature of the bottom surface of the limiting tongue.

[0021] Preferably, as an improvement, several rollers are embedded in both sides of the inner wall of the welding groove.

[0022] Technical benefits: The above-mentioned configuration in this solution effectively reduces the resistance of the hoop seat when entering and exiting the welding groove, thereby improving production efficiency; it also effectively protects the hoop seat and reduces wear caused when it enters and exits the welding groove.

Detailed Implementation

[0034] The following detailed description illustrates the specific implementation method: Example 1 This solution provides a laser welding system for clamps, and a fully automated laser welding and control system for clamps, as shown in the attached document. Figures 2-6 The diagram shows a material feeding and sorting unit, a transfer unit, a welding unit, and a control unit. The control unit includes a vibration controller 71, a transfer controller 72, and a welding robot control device 73. The material feeding and sorting unit is connected to the vibration controller 71 and is used to arrange the hoop seats 1 in an orderly manner into a uniform position. The transfer unit is electrically connected to the transfer controller 72 and is used to transfer the sorted hoop seats 1 to the welding unit. The welding unit includes a welding tank 51, a welding robot, and an unloading assembly. Both the welding robot and the unloading assembly are electrically connected to the welding robot control device 73 and are used to weld the hoop seats 1 and unload and collect them.

[0035] For reference, both the vibration controller 71 and the transfer controller 72 in this solution can be PLC controllers. The electrical components mentioned or to be mentioned in this embodiment (including PLC controllers, welding robot control equipment 73, etc.) can be commercially available products as needed, and their internal structures will not be described in detail.

[0036] like Figure 2As shown, the feeding and sorting unit includes a connected vibratory plate 2, an inclined trough 21, and a sorting groove 3. The vibratory plate 2 includes a plate body and a first vibrator. For structural details of the plate body, please refer to the applicant's previous patent application, "Laser Welding Feeding Fixture for Hoop Seat". A second vibrator 32 is provided at the bottom of the sorting groove 3, and a full-load sensor 31 is provided at the entrance of the sorting groove 3. The first vibrator, the second vibrator 32, and the full-load sensor 31 are all electrically connected to the vibration controller 71. For reference, the full-load sensor 31 can be an infrared detector. The vibration controller 71 is provided with a start button, a stop button, an emergency stop button, and a buzzer, which are used to start, stop, emergency stop, and alarm the first vibrator and the second vibrator 32, respectively. In actual production, after the full-load sensor 31 detects the hoop 1, it transmits a full-load signal to the vibration controller 71. The vibration controller 71 then shuts down the first vibrator based on the full-load signal, facilitating the cessation of material feeding by shutting down the vibratory feeder 2 when the hoop 1 is fully loaded in the sorting groove 3. When the full-load signal disappears (i.e., the full-load sensor 31 no longer detects the hoop 1), the first vibrator is restarted, effectively ensuring the material feeding volume while saving energy. During this process, the vibration controller 71 starts the second vibrator 32 to continuously vibrate and transport the workpieces in the sorting groove 3 to the transfer unit. The control logic of "the full-load sensor 31 transmitting a full-load signal to the vibration controller 71 after detecting the hoop 1" and "the vibration controller 71 shutting down the vibrator based on the full-load signal" is publicly available and implementable control logic in existing equipment, and will not be elaborated here.

[0037] like Figures 3-5 As shown, the transfer unit includes a push-pull component 41, a shifting cylinder 42 that drives the push-pull component 41 to move left and right, a limiting block 45 that restricts the movement range of the push-pull component 41, a transfer detector 43, and a transfer cylinder 44. The shifting cylinder 42 and the limiting block 45 are located at opposite ends of the push-pull component 41. The push-pull component 41 is provided with a transfer groove 411, which is parallel to and offset from the sorting groove 3 and the welding groove 51. When the shifting cylinder 42 pulls the push-pull component 41 so that the inlet of the transfer groove 411 is aligned with the sorting groove 3, the transfer detector 43 is aligned with the outlet of the transfer groove 411. When the shifting cylinder 42 pushes the push-pull component 41 so that the outlet of the transfer groove 411 is aligned with the welding groove 51, the movable end of the transfer cylinder 44 is aligned with the inlet of the transfer groove 411. The top surface of the push-pull component 41 is provided with a cover plate 412 covering the space above the transfer groove 411. The end of the cover plate 412 above the inlet of the transfer groove 411 is higher than the end above the outlet of the transfer groove 411. The top of the limiting block 45 is provided with a limiting plate 451, which extends above the cover plate 412. In this embodiment, the limiting plate 451 is L-shaped. The side plate of the L-shaped limiting plate 451 and the outer side of the limiting block 45 are provided with threaded holes, and the two are fixed by screws and nuts. The top plate of the L-shaped limiting plate 451 is located above the push-pull component 41 to prevent the workpiece inside the push-pull component 41 from jumping and dislodging when the shifting cylinder 42 pushes the push-pull component 41 to move left and right.

[0038] For reference, the transfer detector 43 can be an infrared detector. Both the shift cylinder 42 and the transfer cylinder 44 are magnetic cylinders. Magnetic rings are provided on the piston rods of the shift cylinder 42 and the transfer cylinder 44. The shift cylinder 42 is externally equipped with a first magnetic switch 421, and the transfer cylinder 44 is externally equipped with a second magnetic switch 441. The first magnetic switch 421, the second magnetic switch 441, the shift cylinder 42, the transfer detector 43, and the transfer cylinder 44 are all electrically connected to the transfer controller 72. The second magnetic switch 441 is also electrically connected to the welding robot control device 73.

[0039] Specifically, the pushing and pulling direction of the shifting cylinder 42 is consistent with the long axis direction of the push-pull component 41, the long axis direction of the push-pull component 41 is perpendicular to the conveying direction of the hoop 1, and the transfer groove 411 passes through the short axis direction of the push-pull component 41; the pushing direction of the transfer cylinder 44 is consistent with the transfer direction of the hoop 1, and the shifting cylinder 42 drives the push-pull component 41 to move so that the inlet of the transfer groove 411 alternately aligns with the sorting groove 3 and the moving end of the transfer cylinder 44, and the outlet end of the transfer groove 411 alternately aligns with the transfer detector 43 and the welding groove 51. By combining the transfer groove 411, the transfer detector 43, the shifting cylinder 42 and the transfer cylinder 44, the hoop 1 in the sorting groove 3 can be transferred to the welding groove 51. In actual production, the hoop 1 in the sorting groove 3 enters the transfer groove under the action of the second vibrator 32. After the transfer detector 43 detects that the hoop 1 is in place, it transmits a transfer signal to the transfer controller 72. The transfer controller 72 controls the transfer cylinder 42 to push or pull the push-pull component 41 according to the transfer signal, so that the transfer groove 411 is alternately aligned with the sorting groove 3 and the welding groove 51. When the transfer cylinder 42 pushes the push-pull component 41 into place, it triggers the first magnetic switch 421, thereby starting the transfer cylinder 44 to push the hoop 1 in the welding groove 51 into the welding groove 51. When the transfer cylinder 44 pushes the hoop 1 in the welding groove 51 into the welding groove 51, it triggers the second magnetic switch 441, which starts the transfer cylinder 42 to pull back the push-pull component 41 and start welding. Among them, "the transfer detector 43 transmits a transfer signal to the transfer controller 72 after detecting that the hoop 1 is in place", "the transfer controller 72 starts the transfer cylinder 42 to push the push-pull component 41 according to the transfer signal", "the first magnetic switch 421 is triggered and the transfer cylinder 44 is started", "the second magnetic switch 441 is triggered and the transfer cylinder 44 is started and the push-pull component 41 is pulled back", and "the second magnetic switch 441 is triggered and welding is started" are all control logics that can be implemented by existing equipment, and will not be described in detail here.

[0040] like Figure 3 , Figures 5-6As shown, several rollers 512 are embedded in the middle of the inner walls on both sides of the welding groove 51 to facilitate smoother entry of the hoop 1 into the welding groove 51 or during unloading; a limiting tongue 511 is provided inside the welding groove 51, and an unloading cylinder 513 is provided outside the welding groove 51. A support block is provided for the piston rod of the unloading cylinder 513 to support the piston rod and prevent it from flickering during pushing and pulling, which would affect the accuracy. One end of the limiting tongue 511 is fixed to the inner wall of the end side of the welding groove 51. The external shape of the limiting tongue 511 is adapted to the contour of the inner cavity of the hoop 1. The hoop 1, which is transferred to the welding groove 51, is fitted onto the limiting tongue 511, which facilitates the fixing and limiting of the position of the hoop 1. The unloading cylinder 513 is located behind the limiting tongue 511. The movable end of the unloading cylinder 513 is fixed with an unloading plate 514. The unloading plate 514 is adapted to the curvature of the bottom surface of the limiting tongue 511. An arc-shaped through groove is provided on the inner wall of the end side of the welding groove 51 for the unloading plate 514 to pass through. When the hoop 1 is welded, the unloading plate 514 can extend under the limiting tongue 511 to push out the hoop 1 fitted onto the limiting tongue 511 for unloading. A welding unloading groove 52 is provided below the active area of ​​the push-pull component 41, directly opposite the welding groove 51. A discharge ramp 53 is provided below the welding unloading groove 52. A collection bucket 54 is placed below the discharge ramp 53 to facilitate the collection of the clamp seat 1 pushed out by the discharge piece 514.

[0041] The welding robot includes a fixed base, an upper arm, and a lower arm. A welding assembly is fixed to the movable end of the lower arm. The welding assembly includes a laser generator 61, a welding head 611, an air blowing head 62, and an illumination camera 63. The laser generator 61 has a mounting base 612, which is fixed to the end of the lower arm with screws (this is conventional technology and will not be described further). The air blowing head 62 is connected to a nitrogen tank via an air pipe 621. The air pipe 621 has an air inlet valve to facilitate the creation of a protective atmosphere at the welding point during welding. The camera end of the illumination camera 63 is aligned with the welding point. The wires of the illumination camera 63 are wrapped in a corrugated pipe 631 and fixed to the laser generator 61. The illumination camera 63 is electrically connected to a display 632 for real-time visual tracking of the welding point. The upper arm, lower arm, laser generator 61, air inlet valve, illumination camera 63, display 632, first unloading cylinder 513, and second unloading cylinder 513 are all electrically connected to the welding robot control device 73. The welding robot control device 73 has pre-set information such as the movement trajectory of the upper and lower arms, the power and time of the laser generator 61, and the air pressure. Based on the welding signal transmitted after being triggered by the second magnetic switch 441, the welding robot control device 73 starts the upper arm, lower arm, laser generator 61, and air inlet valve, causing the welding components to weld the clamp 1 in the welding groove 51, and then starts the unloading cylinder 513 to push the clamp 1 to unload. The control logic of "the welding robot control device 73 starting the upper arm, lower arm, laser generator 61, and air inlet valve to weld the weld 13 of the clamp 1 and starting the unloading cylinder 513" is publicly available and can be implemented in existing equipment, and will not be elaborated here.

[0042] After unloading, the hoop 1 slides into the collection bucket 54 along the welded unloading groove 52 and the unloading inclined plate 53.
