Description

Technical Field

[0001] This invention relates to the field of laser welding equipment technology, and in particular to a laser welding device for irregularly shaped copper electronic components. Background Technology

[0002] With the rapid development of electronic technology, irregularly shaped copper electronic components are increasingly widely used in various precision equipment. These components typically have complex structures and often require double-sided soldering to ensure reliable connections.

[0003] Currently, most existing welding equipment uses fixed clamps. After one welding operation is completed, the product needs to be manually disassembled, flipped, and repositioned before welding the other side can be performed. This secondary clamping operation mode is not only cumbersome and severely restricts production efficiency, but also makes it difficult to guarantee repeatability accuracy. It is very easy to generate cumulative errors, resulting in misalignment of the double-sided welds and affecting the welding quality. Secondly, for welding irregularly shaped components, ordinary clamps are difficult to provide a stable constraint during the flipping process, which can easily cause the product to loosen or slip.

[0004] Therefore, in order to improve the ease of welding and reliability of such products, we propose a laser welding device for irregularly shaped copper electronic components. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for manual disassembly, flipping, and repositioning of the product after one welding operation before welding the other side, and to propose a laser welding device for irregularly shaped copper electronic components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a laser welding device for irregularly shaped copper electronic components, including: The machine tool and the transfer mechanism installed on the machine tool; A welding torch is provided on the moving end of the transfer mechanism, and a slide block is slidably connected above the machine base via a conveying mechanism; The slide block has two clamping and flipping mechanisms that are slidably connected to each other above it via a synchronization mechanism. The two clamping and flipping mechanisms are used to clamp and position the product to be welded. The synchronization mechanism is also equipped with a dust removal mechanism.

[0007] Furthermore, the transfer mechanism includes; An X-axis transfer assembly, a Z-axis transfer assembly mounted on the X-axis transfer assembly slide, and a rotating plate rotatably connected to the Z-axis transfer assembly slide, with a height transfer assembly provided on the end face of the rotating plate, and the welding torch fixed to the slide of the height transfer assembly.

[0008] Furthermore, the synchronization mechanism includes; A motor is fixedly installed on the slide block. A rotating plate is fixedly installed on the shaft end of the motor. Two bearing plates are slidably connected above the slide block. The two ends of the rotating plate are respectively pinned to connecting rods that are rotatably connected to the bearing plates.

[0009] Furthermore, the clamping and flipping mechanism includes; A vertical plate fixedly installed above the supporting plate; A flipping motor is fixedly installed on the side of the upright plate. The shaft end of the flipping motor passes through the upright plate and is fixedly installed with a turntable. Two oppositely distributed movable rods are movably inserted into the end face of the turntable. One end of the movable rod is provided with a clamping component, and the other end is provided with a misalignment control component between it and the upright plate.

[0010] Furthermore, the misalignment control component includes; A guide rod is fixedly installed at the end of the movable rod, and a cylindrical cam is fixedly installed on the end face of the upright plate. The end of the guide rod is slidably connected in the slide rail of the cylindrical cam. A spring is provided between the movable rod and the guide rod.

[0011] Furthermore, the clamping member includes; A guide frame is sleeved on the end of the movable rod, and a clamping frame is fixedly installed above the guide frame. A guide groove is provided on the outer side of the guide frame, and a guide member that slides in the guide groove is provided on the outer side of the movable rod. A limiting plate is fixedly installed on the inner side of the guide frame to stop the upper end of the movable rod, and a tension spring is fixedly connected between the guide frame and the movable rod.

[0012] Furthermore, a wedge block is fixedly installed inside the guide frame, and a threaded sleeve is fixedly installed on the end face of the turntable. An abutment rod is connected to the internal thread of the threaded sleeve, and the inclined surfaces of the abutment rod and the wedge block are arranged opposite to each other.

[0013] Furthermore, a sleeve is fixedly installed on the end face of the turntable, and an electrode rod is movably inserted into the inside of the sleeve through a spring. An electrode plate is fixedly installed on the inner wall of the sleeve, and a spring pin is fixedly installed at the inner end of the electrode rod. The electrode rod is located between the two clamping members.

[0014] Furthermore, the dust removal mechanism includes; The suction pipe is rotatably connected to the top of the dust removal mechanism. The bottom of the suction pipe is connected to an external vacuum source through a connector. A filter cover is placed in the opening at the top of the suction pipe.

[0015] Furthermore, a connecting sleeve is movably connected to the outside of the suction pipe via a shock-absorbing spring, and a loading tray is fixedly installed above the connecting sleeve.

[0016] The present invention proposes a laser welding device for irregularly shaped copper electronic components. The beneficial effects are as follows: The present invention places the products to be welded into corresponding clamping and flipping mechanisms. The two clamping and flipping mechanisms are driven to move relative to each other through the synchronization mechanism so that the two clamping and flipping mechanisms move closer to each other until the end faces of the products to be welded are in close contact, thereby forming a precise welding position. The welding torch is controlled to move to the welding position through the transfer mechanism to weld the product. During this process, thanks to the design of the clamping and flipping mechanism, when it is necessary to weld the other side of the product, there is no need to disassemble the product. The product can be flipped directly using the mechanism. This design not only effectively ensures the stable clamping of the product during flipping and double-sided welding, but also avoids the positioning error caused by secondary assembly, thereby significantly improving the double-sided welding efficiency of irregularly shaped electronic components.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-10 As one embodiment of the present invention, a laser welding apparatus for irregularly shaped copper electronic components is disclosed. This laser welding apparatus, by employing a rotary clamping design, enables rotating welding of both sides of the workpiece during the welding of irregularly shaped electronic components. (Refer to...) Figure 1 , Figure 2 Specifically, the welding device includes a machine base 1 and a transfer mechanism 2 installed on the machine base 1; A welding gun 3 is provided on the moving end of the transfer mechanism 2. Of course, in this embodiment, the welding gun 3 is specifically a laser welding gun, which is used to generate a high-energy laser beam to complete the welding. Its specific structure and principle are conventional methods for those skilled in the art, and will not be described in detail here. A slide block 4 is slidably connected above the machine base 1 through the conveying mechanism 10. Reference Figure 3 The slide block 4 is connected to two clamping and flipping mechanisms 6 via a synchronization mechanism 5. The two clamping and flipping mechanisms 6 are used to clamp and position the product to be welded. The synchronization mechanism 5 is also equipped with a dust removal mechanism 7.

[0021] In other words, the present invention places the products to be welded into the corresponding clamping and flipping mechanisms 6 respectively, and drives the two clamping and flipping mechanisms 6 to move relative to each other through the synchronization mechanism 5, so as to drive the two clamping and flipping mechanisms 6 to move closer to each other until the end face of the product to be welded is in close contact, thereby forming a precise welding position. The welding gun 3 is controlled to move to the welding position through the transfer mechanism 2 to weld the product. During this process, thanks to the design of the clamping and flipping mechanism 6, when the other side of the product needs to be welded, there is no need to disassemble the product. The product can be flipped directly using this mechanism. This design not only effectively ensures the stable clamping of the product during flipping and double-sided welding, but also avoids the positioning error caused by secondary assembly, thereby significantly improving the double-sided welding efficiency of irregularly shaped electronic components.

[0022] Reference Figure 3 In some embodiments, the transfer mechanism 2 of the present invention includes; An X-axis transfer assembly 21, a Z-axis transfer assembly 22 mounted on a slide of the X-axis transfer assembly 21, and a rotating plate 23 rotatably connected to a slide of the Z-axis transfer assembly 22 are provided. A height transfer assembly 24 is provided on the end face of the rotating plate 23. The welding torch 3 is fixed on a slide of the height transfer assembly 24.

[0023] Specifically, the X-axis transfer component 21, Z-axis transfer component 22 and height transfer component 24 are preferably ball screw components to ensure movement accuracy. The conveying mechanism 10 adopts a belt drive structure, including pulleys, synchronous belts and drive motors. The drive motor is fixed on the machine base 1 and drives the pulleys to rotate. The synchronous belt is fixedly connected to the bottom of the slide, thereby driving the slide to move back and forth in the Y direction.

[0024] During operation, the X-axis transfer component 21, the Z-axis transfer component 22, the conveying mechanism 10, and the height transfer component 24 cooperate with each other to achieve four-axis displacement adjustment of the welding torch 3 in the X, Y, Z, and height directions within space. In addition, the present invention preferably also has a rotary drive motor fixedly installed on the slide of the Z-axis transfer component 22 to drive the rotating plate 23 to rotate relative to the Z-axis transfer component 22, thereby adjusting the welding angle of the welding torch 3. In this way, through the coordinated cooperation of the above structures, the device realizes five-axis linkage welding operation, which can flexibly cope with the complex spatial curves and multi-angle welding requirements of various irregular products, and greatly improves the adaptability of welding.

[0025] Reference Figure 5 , Figure 6 In an optional embodiment, the synchronization mechanism 5 of the present invention includes; A motor 51 is fixedly installed on the slide block 4. A rotating plate 52 is fixedly installed on the shaft end of the motor 51. Two bearing plates 53 are slidably connected above the slide block 4. The two ends of the rotating plate 52 are respectively pinned to connecting rods 54 that are rotatably connected to the bearing plates 53.

[0026] Specifically, in this embodiment, the motor 51 drives the rotating plate 52 to rotate. The rotating plate 52 converts torque into thrust through the connecting rods 54 at both ends, pushing the two bearing plates 53 to slide synchronously on the slide block 4. When the rotating plate 52 rotates in the forward direction, the connecting rods 54 push the two bearing plates 53 closer to each other, realizing the synchronous approach of the two clamping and flipping mechanisms 6 so that the product edges come into contact. Conversely, when the rotating plate 52 rotates in the reverse direction, it drives the two bearing plates 53 to move away from each other, realizing the release action.

[0027] Reference Figure 6 Based on the above embodiments, the clamping and flipping mechanism 6 in this embodiment of the invention includes a vertical plate 61 fixedly installed above the bearing plate 53; A flipping motor 62 is fixedly installed on the side of the upright plate 61. The shaft end of the flipping motor 62 passes through the upright plate 61 and is fixedly installed with a turntable 63. Two oppositely distributed movable rods 64 are movably inserted into the end face of the turntable 63. One end of the movable rod 64 is provided with a clamping member 65, and the other end is provided with a misalignment control component 66 between it and the upright plate 61.

[0028] Of course, in this invention, the product to be welded is placed between two clamping members 65.

[0029] During operation, the flipping motor 62 drives the turntable 63 to rotate, thereby causing the two movable rods 64 and the clamping parts 65 on them to rotate synchronously, so as to achieve the flipping of the welded parts.

[0030] It is worth noting that during rotation, the mechanical constraint or guidance of the misalignment control component 66 enables dynamic control of the axial position of the movable rod 64. Specifically, when one of the clamping parts 65 rotates to the upper position with the turntable 63, under the action of the misalignment control component 66, the movable rod 64 will be misaligned relative to the turntable 63, thereby causing the corresponding clamping part 65 to move away from the center of the weldment.

[0031] This design allows a large area of ​​the upper surface of the welded product to be exposed, effectively avoiding the interference of the upper clamping parts with the line of sight and path obstruction of the welding gun 3, thereby greatly improving the convenience of welding operation, avoiding welding dead angles or collision damage caused by clamp obstruction, and ensuring the smooth progress of double-sided welding.

[0032] Reference Figure 7 In an optional embodiment, the misalignment control component 66 of the present invention includes; A guide rod 661 is fixedly installed at the end of the movable rod 64, and a cylindrical cam 662 is fixedly installed on the end face of the upright plate 61. The end of the guide rod 661 is slidably connected in the slide of the cylindrical cam 662; wherein, a spring 663 is provided between the movable rod 64 and the guide rod 661.

[0033] The slide of the cylindrical cam 662 is designed with a closed loop curve trajectory. The trajectory of the slide is configured such that, in the upper half of the region corresponding to the welding position, the slide extends concavely away from the turntable 63.

[0034] Its working principle is as follows: When the turntable 63 drives the movable rod 64 to rotate, the guide rod 661 slides in the slide. When any clamping part 65 rotates to the upper position of the welding surface, its corresponding guide rod 661 slides into the concave area of ​​the slide. Under the guidance of the slide side wall, the guide rod 661 is forced to drive the movable rod 64 to move backward away from the turntable, so that the upper clamping part 65 automatically retracts, offsets the welding surface, and makes room for welding.

[0035] Similarly, when turntable 63 continues to rotate 180 degrees, and the clamping component originally positioned below moves to the top, the retraction action described above will be repeated. This design ensures that regardless of which side of the product faces upwards, the clamping component positioned above will automatically retract, thereby achieving continuous avoidance during double-sided welding. Reference Figure 7 Based on the above embodiments, the clamping member 65 in this embodiment of the invention includes: A guide frame 651 is sleeved on the end of the movable rod 64, and a clamping frame 652 is fixedly installed on the upper part of the guide frame 651. A guide groove 653 is provided on the outer side of the guide frame 651, and a guide member that slides in the guide groove 653 is provided on the outer side of the movable rod 64. Optionally, the guide member described in this invention can be a bolt, which slides through the guide groove 653 to guide the guide frame 651. A limiting plate 654 is fixedly installed on the inner side of the guide frame 651 to stop the upper end of the movable rod 64. A tension spring 655 is fixedly connected between the guide frame 651 and the movable rod 64. The tension spring 655 provides elastic tension so that the limiting plate 654 always tends to be pressed against the upper end of the movable rod 64.

[0036] Reference Figure 7 It should be noted that, in this embodiment of the invention, a wedge block 656 is fixedly installed inside the guide frame 651, and a screw sleeve 657 is fixedly installed on the end face of the turntable 63. The screw sleeve 657 is internally threaded with an abutment rod 658, and the abutment rod 658 and the inclined surface of the wedge block 656 are arranged opposite to each other.

[0037] Specifically, the limiting plate 654 described in this invention is used to limit the initial position of the guide frame 651. When the flipping motor 62 drives the turntable 63 to rotate, as mentioned above, the movable rod 64 located above will drive the clamping member 65 to move backward to avoid misalignment. During this backward movement, the abutment rod 658 fixed on the turntable 63 will rotate with the turntable and gradually contact the inclined surface of the wedge block 656. Since the wedge block 656 is fixed on the guide frame 651, when the abutment rod 658 presses against the inclined surface of the wedge block 656 during rotation, a component force perpendicular to the inclined surface will be generated. This component force forces the guide frame 651 to move slightly downward against the tension of the tension spring 655 while moving backward with the movable rod 64. In this way, the clamping frame 652 located on the upper side will make a small downward displacement while shifting backward to avoid the welding line of sight, thereby further pressing the product. This design not only effectively avoids clamp interference, but also increases the clamping force at the same time by using the flipping and avoidance action, which significantly ensures the stability of the product during the double-sided welding process.

[0038] In addition, the contact rod 658 in this invention adopts a threaded connection design, which makes it easy to adjust its extension length according to the product size, thereby adjusting the pressing stroke.

[0039] Reference Figure 8 , Figure 9 It should be noted that a sleeve 67 is fixedly installed on the end face of the turntable 63 in this invention. An electrode rod 69 is movably inserted into the inside of the sleeve 67 through a tower spring 68. An electrode plate 671 is fixedly installed on the inner wall of the sleeve 67. A spring pin 691 is fixedly installed at the inner end of the electrode rod 69. The electrode rod 69 is located between the two clamping members 65.

[0040] Specifically, in this invention, when the synchronization mechanism 5 drives the clamping and flipping mechanisms 6 on both sides to move relative to each other, the two welding parts are clamped on the corresponding clamping parts 65 respectively and gradually move closer to each other. During this process, the electrode rods 69 on the two turntables 63 are pressed against the ends of the corresponding welding parts under the elastic force of the tower springs 68.

[0041] When the synchronization mechanism 5 is driven into position and the mating surfaces of the two welded parts make physical contact, since both welded parts are made of copper, current can form a closed loop through the electrode rod 69 on one side, the welded part, the welded part on the opposite side, and the electrode rod 69 on the opposite side. At this time, the spring pins 691 at the inner ends of the electrode rods 69 on both sides will touch the electrode plates 671 on the inner wall of the sleeve 67 due to the current conduction, and the system will then control the motor 51 of the synchronization mechanism 5 to stop rotating.

[0042] This design utilizes the conductivity of metal parts to achieve automatic positioning of the welding joint, ensuring the stability of the joint. At the same time, thanks to the reverse thrust of the tower spring 68, the electrode rod 69 always applies a continuous elastic thrust to the welded parts, so that the two products maintain a close fit before and during welding, effectively preventing the weld from loosening and further improving the welding quality.

[0043] Reference Figure 10 In some embodiments, the dust removal mechanism 7 of the present invention includes; The suction pipe 71 is rotatably connected to the upper part of the dust removal mechanism 7. The lower part of the suction pipe 71 is connected to an external vacuum source through a connector 72. A filter cover 73 is placed in the upper opening of the suction pipe 71.

[0044] During operation, an external vacuum source generates negative pressure through connector 72, drawing in welding fumes through the upper end of suction pipe 71. After initial interception by filter cover 73, the fumes are discharged through pipeline, thus maintaining a clean working environment. Of course, the filter cover 73 described in this invention can be configured with a movable plug-in installation method, which facilitates subsequent replacement and maintenance.

[0045] It should be noted that the outer side of the suction pipe 71 is movably connected to the connecting sleeve 75 via a shock-absorbing spring 74, and a loading tray 76 is fixedly installed above the connecting sleeve 75.

[0046] Of course, by employing the design of the shock-absorbing spring 74 in this invention, the product falling into the loading tray 76 can be shock-absorbing, thereby improving the reliability of material feeding.

[0047] It should be noted that during the loading and unloading stages, the two movable rods 64 are both located in the non-clamping area of ​​the slide, i.e., the low area on both sides of the slide, under the control of the cylindrical cam 662. At this time, both movable rods 64 are in a retracted state, and the clamping members 65 maintain the maximum distance between them, i.e., in a loose state without applying clamping force.

[0048] In this initial state, the motor 51 controls the two support plates 53 to move towards the loading tray 76, so that the clamping member 65 corresponds vertically with the loading tray 76. At this time, the welded product loses the clamping force and falls naturally into the loading tray 76 below under its own weight or external force, thus completing the automatic unloading.

[0049] Subsequently, the operator or robot fills the clamping area with new products to be welded. Then, the flip motor 62 drives the turntable 63 to rotate, causing the two movable rods 64 to rotate synchronously to the vertical clamping position. At the same time, the cylindrical cam 662 rotates, forcing the movable rods 64 to extend forward and reset. The clamping member 65 then clamps the product, thus completing the loading and entering the next welding cycle.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
