Description

Technical Field

[0001] This utility model relates to the field of accessories for electronic components, and in particular to a screw welding machine. Background Technology

[0002] In the field of electronic component manufacturing, in order to achieve a reliable electrical connection between wires and components, a mechanical fixing method using miniature bolts and auxiliary fixing accessories (such as gaskets and wire terminals) is often used. At the same time, in order to ensure that the connection point remains stable in a vibration environment, a soldering process is usually added on the basis of mechanical fixing, and the accessories and bolts are fused and solidified by soldering to form a composite structure.

[0003] However, due to the tiny size of the bolts and accessories, the installation of accessories and the construction of micro-soldering points in the existing process still rely heavily on manual operation. Operators need to use hand soldering tools to solder after completing the assembly of the accessories. However, the lead-containing fumes and other harmful gases produced by the high-temperature melting of solder materials during this process will cause cumulative occupational health damage to the respiratory system of operators if exposed for a long time. At the same time, the assembly and soldering of tiny bolts and accessories requires workers to maintain a high degree of concentration at all times. This high-intensity work mode not only places stringent demands on the professional skills of workers, but also leads to a loss of focus and a decrease in operating speed as the working time increases. Utility Model Content

[0004] The purpose of this invention is to provide a screw welding machine that automates assembly and welding through multi-mechanism collaboration, thereby avoiding operator exposure to harmful gases generated by solder and improving production efficiency.

The workbench is sequentially equipped with an assembly channel, a welding channel, and a discharge channel. The transfer mechanism has grippers that move back and forth between the assembly channel and the welding channel. The parts loading mechanism has a loading guide rail located near the assembly channel. The bolt loading mechanism has a loading pipe located above the assembly channel. The welding mechanism has a heating gun that moves near the welding channel. The welding mechanism also has a feeding assembly that winds up solder and delivers it to the heating gun.

[0006] As a preferred embodiment, the workbench is equipped with a limiting cylinder, and the output shaft of the limiting cylinder is fixedly connected to a limiting block, which is located between the welding channel and the unloading channel.

[0007] As a preferred embodiment, the transfer mechanism includes a traveling cylinder and a lifting cylinder, wherein the output shaft of the traveling cylinder is fixedly connected to the lifting cylinder, and the output shaft of the lifting cylinder is fixedly connected to the gripper.

[0008] As a preferred embodiment, the accessory feeding mechanism includes a vibratory feeder, and one end of the feeding guide rail is connected to the discharge port of the vibratory feeder.

[0009] As a preferred embodiment, the bolt feeding mechanism includes an air-blowing feeding device and a pressing assembly. One end of the feeding pipe is connected to the outlet of the air-blowing feeding device, and the pressing assembly is provided with a limiting cylinder. The other end of the feeding pipe is connected to the limiting cylinder, and the limiting cylinder is located above the assembly channel.

[0010] As a preferred embodiment, the pressing assembly includes a first mounting bracket and a pressing cylinder. The limiting cylinder is connected to the first mounting bracket. A first slider is slidably connected to the first mounting bracket. The pressing cylinder is fixedly connected to the first mounting bracket.

The material tube is fixedly connected to the connecting rod, and the end of the material tube is close to the heating gun. The feeding motor is fixedly connected to the second mounting bracket, and the feeding motor pushes the solder through the material tube.

[0013] The beneficial effects of the screw welding machine disclosed in this utility model are: The parts feeding mechanism pushes the parts into the assembly channel via the feeding guide rail and is located below the feeding pipe; the bolt feeding mechanism feeds the bolts into the assembly channel via the feeding pipe, so that the bolts are assembled into the parts, completing the initial assembly. The transfer mechanism moves the gripper to the assembly channel. After the gripper clamps the assembled bolt, the transfer mechanism moves it to the welding channel, realizing the movement of the bolt from the assembly channel to the welding channel. At the same time, the parts loading mechanism and the bolt loading mechanism continue to carry out the next round of parts and bolt assembly operations. The welding mechanism moves the heating gun closer to the welding channel, and the feeding component pushes the solder to contact the heating gun. After the solder is heated and melted by the heating gun, it adheres to the joint between the parts and the bolts.

This equipment enables automated, continuous assembly and welding processes without operator intervention, effectively preventing personnel from coming into contact with harmful gases generated during soldering. By assembling one set of components and bolts while simultaneously welding another set, it achieves parallel operation, significantly improving production efficiency. Attached Figure Description

The bottom of the workbench 2 is fixedly connected to multiple support columns. The workbench 2 is mounted on the base 1 through the support columns, thus achieving the suspended mounting of the workbench 2. Furthermore, the workbench 2 is provided with an assembly channel 21, a welding channel 22 and a material unloading channel 23 in sequence, and the assembly channel 21, welding channel 22 and material unloading channel 23 all pass through the workbench 2; the assembly channel 21 is connected to the welding channel 22, and the welding channel 22 is connected to the material unloading channel 23. Furthermore, the width of assembly channel 21 and welding channel 22 are both smaller than the width of accessory 7, and the width of assembly channel 21 and welding channel 22 are both larger than the width of bolt 8, so that accessory 7 can be placed on the edge of assembly channel 21 and welding channel 22 without falling off. After bolt 8 is assembled on accessory 7, the threaded part of bolt 8 can pass through assembly channel 21 and welding channel 22. A limiting plate extends on the worktable 2, and the limiting plate is close to assembly channel 21 and welding channel 22, so that when accessory 7 is placed on assembly channel 21 and welding channel 22, the limiting plate can constrain the position of accessory 7. Furthermore, the width of the unloading channel 23 is greater than the width of the accessory 7, so that the welded accessory 7 and bolt 8 can fall into the unloading channel 23. Furthermore, a sensor 211 is provided on the workbench 2, and the sensor 211 is close to the assembly channel 21.

[0020] The transfer mechanism 3 is equipped with a gripper 31. The transfer mechanism 3 drives the gripper 31 to move back and forth between the assembly channel 21 and the welding channel 22.

The output shaft of the limit cylinder 24 pushes the limit block 241 to be placed between the welding channel 22 and the unloading channel 23, blocking the connection between the welding channel 22 and the unloading channel 23. The output shaft of the limit cylinder 24 pulls the limit block 241 to disengage from the welding channel 22 and the unloading channel 23, opening the connection between the welding channel 22 and the unloading channel 23. When the gripper 31 clamps the bolt 8 and transfers it into the welding channel 22, the limiting cylinder 24 opens the connection between the welding channel 22 and the unloading channel 23, so that the welded parts 7 and bolt 8 can fall into the unloading channel 23; when the welding mechanism 6 performs welding work on the parts 7 and bolt 8, the limiting cylinder 24 closes the connection between the welding channel 22 and the unloading channel 23 to prevent the unfinished parts 7 and bolt 8 from falling into the unloading channel 23.

[0022] The accessory feeding mechanism 4 is equipped with a feeding guide rail 41 and includes a vibrating plate 42. The vibrating plate 42 is fixedly connected to the base 1.

At this time, the bolt 8 is stuck at one end of the limiting cylinder 54. When the accessory 7 is below the limiting cylinder 54, the output shaft of the pressing cylinder 532 pushes the first slider 533 to slide down on the first mounting bracket 531, so that the pressing rod 534 pushes the bolt 8 to disengage from the limiting cylinder 54 and install it into the accessory 7. The output shaft of the pressure cylinder 532 pulls the pressure rod 534 to reset via the first slider 533, and the air-blowing feeding device 52 sends the bolt 8 into the limiting cylinder 54 to carry out the next round of assembly work.

A connecting rod 622 is fixedly connected to the second slider 621, and the heating gun 63 is fixedly connected to the connecting rod 622. The output shaft of the welding cylinder 62 pushes the second slider 621 to slide down on the second mounting bracket 61, so that the second slider 621 pushes the heating gun 63 closer to the fittings 7 and bolts 8 in the welding channel 22 via the connecting rod 622.

[0025] The welding mechanism 6 is equipped with a feeding assembly 64, on which solder 642 is wound up. The feeding assembly 64 conveys the solder 642 to the heating gun 63. The feeding assembly 64 includes a material roll, a material tube 641 and a feeding motor. Furthermore, the material roll is rotatably connected to the second mounting bracket 61.

When part 7 moves below the limiting cylinder 54 and blocks the sensor 211, it is confirmed that part 7 is in place. The pressing cylinder 532 then drives the pressing rod 534 to descend, pushing the bolt 8 away from the limiting cylinder 54 and assembling it onto part 7. Subsequently, the pressing cylinder 532 drives the pressing rod 534 to reset, the air-blowing feeding device 52 continues to feed the next bolt 8, and the vibrating plate 42 simultaneously pushes the subsequent part 7 into the assembly channel 21 for the next round of assembly.
