Description
TECHNICAL FIELD
[0001] The application relates to the field of photovoltaic micro-inverter processing, in particular to a component welding device for photovoltaic micro-inverter production. BACKGROUND
[0002] As a new type of photovoltaic grid-connected device, the photovoltaic micro-inverter can convert direct current generated by a solar panel into alternating current to meet household and commercial power demand. Unlike traditional centralized inverters, the micro-inverter is provided with one inverter for each solar panel, and has a very wide development prospect.
[0003] After various parts required by the photovoltaic micro-inverter are produced, the parts need to be welded to the circuit board by tin. Most factories still manually hold the welding equipment to weld the components on the circuit board. The components are relatively small, so the components are prone to sliding during processing, and the welding is not accurate enough. Some factories now use welding devices for welding, but most ordinary welding devices cannot continuously weld the pins of four surfaces of the components, so the welding efficiency is not high enough. SUMMARY
[0004] The purpose of the application is to provide a component welding device for photovoltaic micro-inverter production which can continuously weld the pins of four surfaces of the components and fix the components during the welding process.
[0005] A component welding device for photovoltaic micro-inverter production, comprising supporting legs, a workbench, a mounting disc, a welding mechanism and a rotating mechanism. The supporting legs are fixedly connected to the top of the workbench. The mounting disc is rotatably connected to the top of the workbench. The welding mechanism is arranged on the top of the mounting disc. The rotating mechanism is arranged on the outer wall of the mounting cylinder.
[0006] Further, the welding mechanism comprises an electric push rod, a mounting cylinder, a pressing plate, a vertical spring and a welding plate. The electric push rod is fixedly connected to the top of the mounting disc. The bottom of the telescopic rod of the electric push rod is fixedly connected to the mounting cylinder. The pressing plate is slidably connected to the bottom of the mounting cylinder. The vertical spring is fixedly connected between the pressing plate and the mounting cylinder. The welding plate is fixedly connected to the outer wall of the mounting cylinder.
[0007] Further, the rotating mechanism comprises an inclined ring, an inclined block, a horizontal spring, a rack one, an overrunning clutch and a gear one. The inclined ring is fixedly connected to the outer wall of the mounting cylinder. The inclined block is slidably connected to the workbench. The horizontal spring is fixedly connected between the inclined block and the workbench. The inclined block is fixedly connected to the bottom of the rack one. The telescopic rod of the electric push rod is fixedly connected to the overrunning clutch. The overrunning clutch is fixedly connected to the gear one. The gear one is engaged with the rack one.
[0008] Further, the smearing mechanism is arranged on the lower part of the workbench, and comprises an elastic frame, a sliding frame, a return spring, a smearing head and a storage cylinder.
[0009] Further, the scraping mechanism is arranged on the pressing plate, and comprises a scraper, a cylindrical spring, a wedge block, a hinged plate and a torsion spring one.
[0010] Further, the scraping mechanism is arranged on the pressing plate, and comprises a scraper, a cylindrical spring, a wedge block, a hinged plate and a torsion spring one.
[0011] Further, the scraping mechanism is arranged on the pressing plate, and comprises a scraper, a cylindrical spring, a wedge block, a hinged plate and a torsion spring one.
[0012] Further, the scraping mechanism is arranged on the pressing plate, and comprises a scraper, a cylindrical spring, a wedge block, a hinged plate and a torsion spring one.
[0013] The present application has the following advantages: 1. The inclined ring limits the inclined block, so that the horizontal spring is in a compressed state. The operator places the component on the workbench, and then starts the electric push rod. The inclined ring moves downward and is out of contact with the inclined block. The movement of the rack one will squeeze the gear one. The rotation of the electric push rod drives the installation cylinder, the pressing plate, the welding plate and the inclined ring to rotate. The installation cylinder continues to move downward through the vertical spring to drive the pressing plate to continue to move downward until the welding plate contacts the pin on one side of the component. The welding plate welds the pin on one side of the component. This reciprocating movement ensures that the pins on four sides of the component are welded, improving the efficiency of welding.
[0014] 2. When the telescopic rod of the electric push rod rotates, the sliding frame will rotate, so that the storage cylinder slides on the sliding rail driven by the inclined ring. The elastic frame limits the storage cylinder, so that the rosin in the storage cylinder can be applied to the bottom of the welding plate, so that the rosin on the storage cylinder removes the tin remaining on the bottom of the welding plate, so as to facilitate the welding plate to weld the pins of the component again.
[0015] 3、When the pressing plate moves downward and contacts the component, the component will extrude the four positioning plates, so that the four positioning plates swing downward, the four torsion springs will be twisted, and the downward swinging of the four positioning plates will be buckled on the four side walls of the component, the four positioning plates can better limit the component, so that the component is not easy to slide during processing, and the accuracy of component welding is improved.

Detailed Implementation
[0029] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.
[0030] Example 1: A component welding device for photovoltaic micro-inverter production, such as... Figures 1-8 As shown, it includes a support leg 1, a worktable 2, a mounting plate 3, a welding mechanism, and a rotating mechanism. The top of the support leg 1 is bolted to the worktable 2, and the top of the worktable 2 is rotatably connected to the mounting plate 3. The mounting plate 3 is horizontally positioned. The welding mechanism is located on the top of the mounting plate 3, and the rotating mechanism is located on the outer wall of the mounting cylinder 42.
[0031] The welding mechanism includes an electric push rod 41, a mounting cylinder 42, a pressing plate 43, a vertical spring 44, and a welding plate 45. The top of the mounting plate 3 is connected to the electric push rod 41 by bolts. The electric push rod 41 is vertically arranged. The bottom of the telescopic rod of the electric push rod 41 is connected to the mounting cylinder 42 by bolts. The bottom of the mounting cylinder 42 is slidably connected to the pressing plate 43. The pressing plate 43 and the mounting cylinder 42 are connected by a hook and a vertical spring 44. The outer wall of the mounting cylinder 42 is welded with a welding plate 45.
[0032] The rotating mechanism includes a slanted ring 51, a slanted block 52, a horizontal spring 53, a rack 54, an overrunning clutch 55, and a gear 56. The slanted ring 51 is bolted to the outer wall of the mounting cylinder 42. A rectangular plate is mounted on one side of the slanted ring 51, and a slide rail is mounted on the lower side of the rectangular plate. The slanted block 52 is slidably connected to the worktable 2. The horizontal spring 53 is connected to the slanted block 52 and the worktable 2 through a hook. The rack 54 is bolted to the lower part of the slanted block 52. The overrunning clutch 55 is bolted to the telescopic rod of the electric push rod 41. The gear 56 is connected to the overrunning clutch 55 through a flat key. The gear 56 meshes with the rack 54.
[0033] Initially, the inclined ring 51 limits the inclined block 52, causing the horizontal spring 53 to be in a compressed state. First, the operator places the component on the workbench 2, and then the operator activates the electric push rod 41, causing the extension rod of the electric push rod 41 to extend. The extension of the extension rod of the electric push rod 41 drives the mounting cylinder 42 and the pressing plate 43 to move downward. The downward movement of the mounting cylinder 42 drives the welding plate 45 to move downward. The downward movement of the mounting cylinder 42 drives the inclined ring 51 to move downward. The downward movement of the inclined ring 51 disengages from the inclined block 52, and the horizontal spring 53 returns to its original position. The return of the horizontal spring 53 drives the inclined block 52 to move away from the electric push rod 41. The movement of the inclined block 52 away from the electric push rod 41 drives the rack 54 to move in one of the directions. The movement of the 54th motor compresses the gear 56, causing it to rotate. This rotation drives the overrunning clutch 55, which in turn drives the electric push rod 41. The electric push rod 41 then rotates the mounting cylinder 42, the pressing plate 43, the welding plate 45, and the inclined ring 51, until the inclined ring 51 completely disengages from the inclined block 52. At this point, the electric push rod 41 and the pressing plate 43 have rotated exactly ninety degrees. The mounting cylinder 42 continues to move downwards, driving the pressing plate 43 downwards via the vertical spring 44, until the pressing plate 43 contacts the components on the worktable 2. The pressing plate 43 presses down on the components, preventing them from slipping during welding. At this point, the telescopic rod of the electric push rod 41 extends further, causing the mounting cylinder 42 to move along the pressing plate... As plate 43 slides downwards, vertical spring 44 is compressed. Mounting cylinder 42 continues to move downwards, causing welding plate 45 to continue moving downwards until welding plate 45 contacts one of the component's pins. Welding plate 45 then welds the pins on one side of the component. After welding, the operator adjusts electric push rod 41, causing its telescopic rod to retract. This retraction of electric push rod 41 moves mounting cylinder 42 upwards, which in turn moves welding plate 45 upwards, disengaging welding plate 45 from the component's pins. Simultaneously, the upward movement of mounting cylinder 42 moves inclined ring 51 upwards, causing inclined ring 51 to press against inclined block 52, causing inclined block 52 to move closer to electric push rod 41. Spring 53 is stretched, and the inclined block 52 moves towards the electric push rod 41, causing gear 56 to rotate in the opposite direction. The reverse rotation of gear 56 causes the overrunning clutch 55 to rotate in the opposite direction. The reverse rotation of the overrunning clutch 55 does not cause the electric push rod 41 to rotate until the extension rod of the electric push rod 41 is reset. The operator then adjusts the extension rod of the electric push rod 41 again, causing the extension rod of the electric push rod 41 to extend. The extension of the extension rod of the electric push rod 41 again causes the mounting cylinder 42 to move downward, causing the inclined ring 51 to rotate again during the downward movement. This causes the mounting cylinder 42 to rotate, which in turn causes the welding plate 45 to rotate 90 degrees and contact the other side pin of the component. This process is repeated to ensure that all four sides of the component's pins are welded, improving welding efficiency.
[0034] Example 2: Based on Example 1, such as Figures 4-8 As shown, it also includes a coating mechanism, which is located at the lower part of the workbench 2. The coating mechanism includes an elastic frame 61, a sliding frame 62, a return spring 63, a coating head 64, and a storage cylinder 67. The elastic frame 61 is welded to the lower part of the workbench 2. The elastic frame 61 is made of iron material that will deform under force. The sliding frame 62 is bolted to the telescopic rod of the electric push rod 41. The lower part of the sliding frame 62 has a sliding groove. The coating head 64 is slidably connected in the sliding groove at the lower part of the sliding frame 62. The return spring 63 is connected to the coating head 64 and the sliding frame 62 through a hook. The storage cylinder 67 is bolted to one end of the coating head 64. The storage cylinder 67 is connected to the coating head 64 and is slidably connected to the slide rail on the inclined ring 51.
[0035] When the telescopic rod of the electric push rod 41 rotates, it drives the sliding frame 62 to rotate. At the same time, the inclined ring 51 rotates, driving the storage cylinder 67 to rotate. When the storage cylinder 67 rotates to contact the elastic frame 61, the elastic frame 61 limits the movement of the storage cylinder 67, causing it to stop. Meanwhile, the sliding frame 62, welding plate 45, and inclined ring 51 continue to rotate, compressing the return spring 63, causing the storage cylinder 67 to slide on the slide rail provided on the inclined ring 51. Simultaneously, the rosin inside the storage cylinder 67 can be applied to the bottom of the welding plate 45 until the storage cylinder 67 slides to the inclined ring 51. At the end of the slide rail on the ring 51, the slide rail on the inclined ring 51 will limit the storage cylinder 67, so that the storage cylinder 67 continues to move with the inclined ring 51. The storage cylinder 67 will squeeze the elastic frame 61, causing the elastic frame 61 to deform and bend until the elastic frame 61 bends to the point that the storage cylinder 67 passes through. The reset spring 63 will reset, and the reset spring 63 will drive the storage cylinder 67 to brush over the soldering plate 45 again. This process is repeated, so that the rosin on the storage cylinder 67 removes the residual solder at the bottom of the soldering plate 45, so that the soldering plate 45 can be used to solder the pins of the components again.
[0036] Example 3: Based on Example 2, such as Figures 4-10 As shown, it also includes a scraping mechanism, which is mounted on the pressing plate 43. The scraping mechanism includes a scraper 71, a cylindrical spring 72, a wedge block 73, a hinge plate 74, and a torsion spring 75. The scraper 71 is slidably connected to the pressing plate 43 and is horizontally positioned. Two cylindrical springs 72 are connected to the scraper 71 and the pressing plate 43 via hooks. A wedge block 73 is welded to one end of the scraper 71. The bottom of the sliding frame 62 is rotatably connected to the hinge plate 74. Two torsion springs 75 are connected to the hinge plate 74 and the sliding frame 62 via hooks.
[0037] When the sliding frame 62 and the pressing plate 43 move downward together, they will drive the scraper 71, cylindrical spring 72, wedge block 73, and hinge plate 74 downward. The wedge block 73 will squeeze the hinge plate 74, causing the hinge plate 74 to swing downward. The torsion spring 75 will be torn, and the sliding frame 62 will continue to move downward, driving the wedge block 73 to continue moving downward until the wedge block 73 disengages from the hinge plate 74. The torsion spring 75 will then return to its original position, causing the hinge plate 74 to swing upward. When the sliding frame 62 and the pressing plate 43 move upward together, the wedge block 73 will engage with the hinge plate 74. 4. When the bottom contacts the hinge plate 74, it will squeeze the wedge block 73, causing the wedge block 73 to move away from the pressing plate 43. The movement of the wedge block 73 away from the pressing plate 43 will drive the scraper 71 to move away from the pressing plate 43. The two cylindrical springs 72 will be stretched. The scraper 71 will move away from the pressing plate 43 and contact the bottom of the welding plate 45, thereby scraping away the impurities adhering to the bottom of the welding plate 45. Until the wedge block 73 disengages from the hinge plate 74, the two cylindrical springs 72 will return to their original position. The return of the two cylindrical springs 72 will drive the scraper 71 to return to its original position.
[0038] Example 4: Based on Example 3, such as Figures 6-7 As shown, it also includes an elastic plate 81, a hammer 82, and a torsion spring 83. Several elastic plates 81 are bolted to the bottom of the sliding frame 62. The hammer 82 is rotatably connected to the storage cylinder 67. A torsion spring 83 is rotatably connected between the hammer 82 and the storage cylinder 67.
[0039] When the storage cylinder 67 slides back and forth on the sliding frame 62, it causes the bottom of the striking hammer 82 to come into contact with several elastic plates 81 in sequence. One of the elastic plates 81 will squeeze the striking hammer 82, causing the striking hammer 82 to move away from the storage cylinder 67. The second torsion spring 83 will be twisted until the striking hammer 82 continues to move and disengages from one of the elastic plates 81. The second torsion spring 83 will then reset, and the reset of the second torsion spring 83 will cause the striking hammer 82 to reset. This process repeats, causing the striking hammer 82 to strike the storage cylinder 67, thereby allowing the rosin in the storage cylinder 67 to flow out smoothly.
[0040] Example 5: Based on Example 4, such as Figures 11-12 As shown, it also includes a positioning plate 91 and a torsion spring 92. The bottom of the pressing plate 43 is rotatably connected to four positioning plates 91 for limiting the movement of components. The four positioning plates 91 are inclined. The pressing plate 43 is rotatably connected to the four positioning plates 91 respectively with torsion springs 92.
[0041] When the pressing plate 43 moves downward and contacts the component, the component will squeeze the four positioning plates 91, causing the four positioning plates 91 to swing downward. The four torsion springs 92 will be twisted, and the four positioning plates 91 will swing downward and lock onto the four side walls of the component. The four positioning plates 91 can better limit the component, making it less likely to slip during processing and improving the accuracy of component welding. Until the pressing plate 43 moves upward and the component no longer squeezes the four positioning plates 91, the four torsion springs 92 will reset. The reset of the four torsion springs 92 will drive the four positioning plates 91 to swing upward and no longer lock onto the component.
[0042] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
