Description

Technical Field

[0001] The invention belongs to the technical field of fuse welding, and in particular relates to a self-healing capacitor element automatic fuse assembly welding system and method. Background Art

[0002] The low-voltage self-healing capacitor element and the fuse assembly are bent and welded. The self-healing capacitor element is a cylinder formed by winding two layers of metalized film, and metal particles are attached to the two end faces to form the plates. The existing low-voltage self-healing capacitor element welding process adopts manual picking of the fuse assembly, inserting it into the component, manually assisting in flipping it, and controlling the electric soldering iron for soldering by a foot switch. The solder joint size control deviation is large, and the soldering iron tip is manually cleaned and finally manually judged visually. The fuse assembly is manually inserted, bent and flipped, and then welded. The angle deviation between the lead wire A and the wire 1 after welding is large, and the consistency is also poor, which increases the difficulty of the back-end assembly and fixing bracket process. The manual circulation of components and parts adopts batch handling, which occupies a large area.

[0003] Patent application with publication number CN115740875A: A metallized capacitor element automatic welding machine, comprising a base, a fixed plate is arranged on the top of the base; a capacitor welding machine body is arranged on the top of the front side of the fixed plate; a support plate is arranged on the front side of the fixed plate, mounting blocks are arranged on both sides of the top of the support plate, electric telescopic rods are arranged on the opposite sides of the two groups of mounting blocks, and fixed blocks are arranged on the output ends of the two groups of electric telescopic rods; the top support net is attached to the support plate, and the bottom support net is attached to the baffle, so that when the slide plate pushes the welding slag on the collection net, it is not necessary to stop the continued welding of the capacitor element, because the welding slag generated during welding can still be sucked onto the support net by passing through the collection net and the support net in turn through the wind force, and when the slide plate is retracted to the bottom of the support plate, the welding slag falling on the support net can be pushed back to the collection net by the support plate and the baffle, so as to continue to be pushed away by the slide plate, but the prior art mainly discusses the automatic collection of welding slag by the welding station, and does not involve the welding process.

[0004] Our company currently uses manual disassembly of incoming materials, manual insertion, bending, and flipping of parts for assembly, hand-pressing switch control components to open and close the clamping module, ordinary electric soldering iron welding, manual cleaning of the soldering iron tip, and manual inspection. The disadvantages are manual assembly, manual circulation, manual inspection, large footprint, and a relatively messy on-site production environment.

[0020] Furthermore, a funnel-shaped guiding mechanism is used to realize automatic insertion of the fuse assembly through the opening and closing matching of the left clamp and the right clamp, which can effectively reduce the difficulty of perforation caused by the tilting and deformation of the fuse and reduce the tolerance standard of the automatic welding for the incoming materials.

[0029] Wherein: the automatic feeding system puts the fuse assembly 6 into the silo 1, controls the dropping speed and the dropping amount of the silo 1, so that the fuse assembly 6 falls onto the circular vibration plate 2, and the circular vibration plate 2 sends the fuse assembly 6 into the linear vibration feeder 3 for arrangement.

[0030] A fuse assembly grabbing module 4 is arranged at the front top of the linear vibration feeder 3 . The fuse assembly grabbing module 4 has a sliding grabbing mechanism. The grabbing mechanism grabs the fuse assembly 6 arranged at the front end of the linear vibration feeder 3 .

[0031] A funnel-shaped guide mechanism 5 is provided at the bottom of the fuse assembly grabbing module 4. When the fuse assembly module 4 is fed into the fuse assembly 6, the split left clamp block 5a and the split right clamp block 5b are in a closed state, and a funnel-shaped hole is formed in the middle. When the fuse assembly module 4 moves downward and reaches a preset position, the split left clamp block 5a and the split right clamp block 5b are opened to ensure that the fuse assembly 6 can be accurately inserted into the center of the self-healing capacitor element 7, which is called process 1. A conveying mechanism 12 is provided at the bottom of the funnel-shaped guide mechanism 5. A plurality of component carriers 8 are provided on the upper part of the conveying mechanism 12 to clamp or release the self-healing capacitor element 7, fix the self-healing capacitor element 7, and automatically step to the next self-healing capacitor element 7 after one is inserted. The fuse assembly 6 is inserted into the internal hole of the self-healing capacitor element 7, which is called the first semi-finished component.

[0032] The rear end process of the funnel-shaped guiding mechanism 5 is provided with a fuse pressing mechanism 9 and a bending mechanism 10. The first semi-finished component and the component carrier 8 integrally slide in steps to the rear end process. The fuse pressing mechanism 9 moves from top to bottom to press the fixing plug 18 in the first semi-finished component. Then, the cylinder in the bending mechanism 10 drives the pressing block to move upward to the side of the component fuse first, and then the pressing block moves to the right to complete the bending of the end of the fuse, which is called process 2. The fuse pressing mechanism 9 is located at the upper end of the component carrier 8, and the bending mechanism 10 is located at the lower end of the component carrier 8; the first semi-finished component and the component carrier 8 integrally slide to the process 2 through the conveying mechanism 12, complete the pressing of the fixing plug 18 and the bending of the end of the fuse 19, and form a second semi-finished component.

[0033] The bending mechanism 10 is provided with the flipping system 13 and the soldering system 11 at the rear end. The second semi-finished component and the component carrier 8 are integrally stepped and slid to the rear process. The flipping system 13 includes a fixed end and a rotating end. The fixed end can move up and down. The rotating end is connected with a clamp. When in use, the clamp clamps the component, the fixed end moves up, and the rotating end drives the clamp to rotate, so that the component flips 180°, and then solders it through the soldering system 11. The soldering system 11 includes an eddy current soldering iron 11a, an automatic soldering machine 11b and a tin blowing mechanism 11c. After the soldering is completed, the self-healing capacitor component 7 is put back in reverse, which is called process 3. The second semi-finished component and the component carrier 8 are integrally slid to the process 3 through the conveying mechanism 12, and flipped and soldered. After completion, the third semi-finished component is formed. The back-end process of the flipping system 13 and the soldering system 11 is provided with a quality inspection and control system 16, which is called process 4. The third semi-finished product assembly and the component carrier 8 are slid as a whole to the process 4 through the conveying mechanism 12 to perform image inspection and analysis to determine whether the quality of the solder joint 20 meets the requirements. When performing impact inspection and analysis, the light source 15 provided on the frame 21 is used for illumination to cooperate with the inspection.

[0034] The present invention divides the welding of low-voltage self-healing capacitor element fuses with automatic welding requirements into 8 parts, namely, the first part is a feeding system, the second part is a fuse module grabbing part, the third part is a funnel-shaped guiding mechanism, the fourth part is a component carrier, the fifth part is a transmission mechanism, the sixth part is a fuse pressing and bending mechanism, the seventh part is a turning system, and the eighth part is a soldering and quality inspection control system, so as to complete the automatic welding and quality inspection process of the fuse assembly. The feeding part adopts the method of vibrating disk feeding bin. This method has sufficient fuse discharge quantity, stable discharge and reduces the frequency of feeding. A special module mechanism is used to grab the fuse component, which has accurate positioning. The funnel-shaped guide mechanism can effectively reduce the difficulty of perforation caused by the tilt and deformation of the fuse. The component carrier that penetrates the fuse component slides to the fuse pressing and bending mechanism through the transmission mechanism. The fuse component is first pressed with a fixed plug and then bent, which can improve the assembly accuracy of welded parts. The eddy current soldering iron is used for soldering, which has high heating efficiency, fast speed, low consumption and environmental protection, real-time monitoring of temperature and welding time, and data analysis through database and MES and other information systems to achieve process control. Finally, the quality inspection system and image inspection of welding quality are used to ensure excellent processing quality and greatly improve welding efficiency.

When reaching the preset position, the split left clamp block 5a and the split right clamp block 5b of the funnel-shaped guide mechanism 5 are separated, and the fuse assembly 6 continues to vertically descend until the large circle lower end surface of the fixing plug 18 coincides with the upper end surface of the self-healing capacitor element 7, and the fuse assembly 6 is accurately inserted into the center of the self-healing capacitor element 7 to form a first semi-finished assembly; The first semi-finished assembly and the component carrier 8 are transported as a whole to the fuse pressing mechanism 9 through the conveying mechanism 12. The fuse pressing mechanism 9 descends vertically to complete the pressing of the fixing plug 18. Then, the pressing block (the gap arc with the fuse) in the bending mechanism 10 moves left and right to complete the bending of the fuse 19, thereby forming a second semi-finished assembly. The second semi-finished component (such as Figure 5 ) and the component carrier 8 are transported to the flipping mechanism 13 as a whole through the conveying mechanism 12. Through the flipping action, the second semi-finished component of the self-healing capacitor component 7 and the fuse component 6 is flipped 180 degrees. At this time, the end of the fuse component 6 faces upward, and the eddy current soldering iron 11a in the soldering system 11 tilted at an appropriate angle vertically descends to the end of the fuse component 6 of the self-healing capacitor component 7. The side of the eddy current soldering iron 11a is equipped with an automatic tin feeding machine 11b to complete the synchronous feeding of the solder wire, complete the welding of the fuse component 6, and form a third semi-finished component; The eddy current soldering iron 11a places the soldering iron tip into the cleaning tank 14 to complete automatic cleaning within a fixed time; The third semi-finished component (such as Figure 7 ) and the component carrier 8 are transported to the quality inspection control system 16 through the transmission mechanism 12, and the end face of the fuse end of the self-healing capacitor element 7 with the welding point 20 is photographed.
