Description

Technical Field

[0001] The invention relates to the technical field of power source processing, in particular to a fixed-point welding device used for power source processing. Background Art

[0002] A power supply is a device that can convert other forms of energy into electrical energy and provide electrical energy to circuits (electronic devices). In the process of power supply processing, a soldering machine is often needed for spot welding. For example: using a soldering machine to weld cables on the metal conductive sheet of a power socket, a complete conductive path is established from the external power supply to the socket, and then to the electrical device plugged into the socket, so that the current can be transmitted smoothly, thereby powering the electrical device.

[0003] When the cable is soldered to the metal conductive sheet of the power socket by a soldering machine, the core of the cable is usually exposed, and the core and the metal conductive sheet are attached together. Then, the solder head of the soldering machine moves down and the tin bar is quickly connected and transported to melt the tin bar at the core and the metal conductive sheet, thereby completing the welding. However, some cables have multiple loose cores, which are not convenient to twist or twist into one strand. After such a core is soldered to the metal conductive sheet of the power socket by a soldering machine, it will not only affect the electrical performance (such as increased resistance), but also affect the mechanical performance (such as reduced connection strength and poor fatigue resistance), thereby affecting the processing quality of the power supply. At the same time, such a core is not convenient to quickly pass through the small holes on the metal conductive sheet and use a soldering machine to weld (commonly known as perforation welding), which affects the processing efficiency and quality of the power supply.

[0033] The synchronous movement mechanism includes a connecting block 17 and a collar 23. The connecting block 17 is fixedly connected to the side wall of the support plate 3 near the upper edge, and the end of the connecting block 17 away from the support plate 3 is fixedly connected with a spiral ring 22, and the spiral ring 22 is located on the outside of the rotating tube 18.

A slider 29 is fixedly connected to the outer wall of the collar 23, and the lower end of the slider 29 is in contact with the upper surface of the spiral ring 22.

[0034] In this embodiment, the electric push rod 4 is first started to drive the pressure rod 6 to move upward, and the pressure rod 6 will slide up with the four plug blocks 38 in the four slots 13 on the cushion rod 10 respectively until the spacing between the pressure rod 6 and the cushion rod 10 meets the two conductive plates of the power socket 2. The two conductive plates of the power socket 2 are inserted between the two adjacent plug blocks 38 and between the pressure rod 6 and the cushion rod 10 respectively, and then the electric push rod 4 is used to drive the pressure rod 6 to move downward until the pressure rod 6 presses and fixes the two conductive plates of the power socket 2. At this time, the power socket 2 is also fixed. Figure 2 As shown, at this time, the centers of the small holes of the two conductive sheets of the power socket 2 correspond to the centers of the two rotating tubes 18 respectively.

[0035] Then, a power cable 8 is first inserted along the bottom of a branch pipe 28. Both the branch pipe 28 and the rotating tube 18 are transparent bodies. The power cable 8 can be placed between the two sets of electric guide wheels 31. Finally, the micro bidirectional slide 9 is started to drive the two support blocks 12 to move closer to each other. The two support blocks 12 can drive a set of connecting rods 14 connected to each other to slide in the two sets of slide grooves 11 respectively. The two sets of connecting rods 14 can drive the electric guide wheels 31 connected to each other to slightly squeeze the outer surface of the power cable 8. Then, the two sets of electric guide wheels 31 are started, and the two sets of electric guide wheels 31 rotate accordingly, and will drive the power cable 8 to move vertically upward until the exposed wire core of the power cable 8 corresponds to the multiple rubber pads 19, as shown in FIG. Figure 4 and Figure 5 As shown, the support blocks 12 are then driven to move closer to each other by the micro bidirectional slide 9 again, until the two sets of electric guide wheels 31 are driven to clamp and fix the power cable 8. The power socket 2 and the power cable 8 are both parts of the power supply device.

[0036] Then, the motor 7 is started to drive the gear 27 to rotate, and the gear 27 will drive the ring gear 24 to rotate, and the ring gear 24 will drive the rotating tube 18, multiple connecting columns 30, multiple square shells 20, multiple rubber pads 19, multiple blocks 26, multiple springs 15, collars 23, multiple connecting plates 25, springs 216, fixed rings 21 and sliders 29 to rotate together. When the slider 29 rotates, it will move upward while rotating along the spiral surface of the spiral ring 22. The spiral ring 22 is fixed to the support plate 3 through the connecting block 17 and the position does not change, and the slider 29 will also move upward while rotating with the collar 23. During the upward movement of the collar 23, the spring 216 connected to the fixed ring 21 will be squeezed, and during the upward movement of the collar 23, the multiple connecting plates 25 will be driven to rotate upward synchronously. The multiple connecting plates 25 will drive the blocks 26 connected to each other to move toward the rotating tube 18 synchronously. The blocks 26 can drive the connected connecting columns 30 to slide in the inner wall of the rotating tube 18 toward the axis of the rotating tube 18, and the multiple blocks 26 can squeeze the spring 15 connected to the rotating tube 18, the multiple connecting columns 30 can drive the connected square shells 20 to move toward the axis of the rotating tube 18, and the multiple square shells 20 can drive the connected rubber pads 19 to move toward the axis of the rotating tube 18. In summary, the multiple rubber pads 19 will rotate while approaching the core of the power cable 8. Finally, the contact between the multiple rubber pads 19 and the core can gather and twist the cores that were originally multiple bundles and loose (it should be noted that when the core of the power cable 8 is twisted, because the outer sheath of the power cable 8 has been fixed by two sets of electric guide wheels 31, the power cable 8 can still remain stable when the core of the power cable 8 is twisted), so that the core becomes one strand. Then, the motor 7 is turned off, and the multiple rubber pads 19 are kept pressing the wire core for a period of time to shape it, and then the motor 7 is started again and the gear 27 is reversed. Then, according to the opposite principle and the reaction force of the spring 1 15 and the spring 2 16, the multiple rubber pads 19 will rotate and move away from the wire core of the power cable 8. Similarly, another power cable 8 is inserted along the bottom of another branch pipe 28, and the wire core of the other power cable 8 will also be gathered and twisted, and fit together tightly.

[0037] Finally, the two sets of electric guide wheels 31 are controlled by the micro bidirectional slide 9 to lightly clamp the power cable 8, and the two sets of electric guide wheels 31 are started to rotate to drive the power cable 8 to move vertically upward continuously, and then the core of the power cable 8 will quickly pass through the small holes of the conductive sheet on the power socket 2, and then the solder head 1 is tilted downward to squeeze and twist the core into a strand, and then the tin bar is quickly connected and transported, and the core will be welded to the conductive sheet on the power socket 2 to complete the perforation welding. The power cable 8 that is squeezed, gathered and twisted into a strand has closer contact between its cores, which improves the reliability of electrical performance and the strength of mechanical performance, thereby improving the processing quality and efficiency of the power supply.

[0038] Example 2: Please refer to Figure 6 and Figure 7 The present embodiment further explains the first embodiment. The replenishing mechanism includes a spacer 36 and a discharge pipe 37. The spacer 36 is fixedly connected to the inner wall of the square shell 20 near the upper edge. The discharge pipe 37 is movable and passes through the rubber pad 19 and the wall surface of the square shell 20 near the axis of the rotating tube 18 in sequence. A hole groove 33 is opened on the outer wall of the discharge pipe 37. The discharge pipe 37 is located above the spacer 36. A spring 35 is fixedly connected between one end of the discharge pipe 37 located inside the square shell 20 and the inner wall of the square shell 20.

[0039] The replenishing mechanism also includes a sealing ring 34 , which is fixedly embedded in the inner wall of the square shell 20 corresponding to the dosage tube 37 , the hole groove 33 corresponds to the sealing ring 34 , and the inner ring surface of the sealing ring 34 fits the outer wall of the dosage tube 37 .

[0040] In this embodiment, when the multiple rubber pads 19 rotate and move close to the wire core, they can gather and twist the wire cores that were originally multiple and loose, so that they form a strand. At this time, each rubber pad 19 will form an extrusion state with the wire core, and each rubber pad 19 will undergo a certain deformation. Then, during the deformation process, each rubber pad 19 will drive the respectively connected agent outlet tube 37 to slide into the corresponding square shell 20, and the agent outlet tube 37 will squeeze the spring three 35 connected to the square shell 20, and the agent outlet tube 37 will slide in the sealing ring 34, and the hole groove 33 on the agent outlet tube 37 will move into the corresponding square shell 20. The square shell 20 contains flux, and the flux will enter the agent outlet tube 37 along the hole groove 33 and fall along the opening of the agent outlet tube 37 onto the surface of the gathered and twisted wire core. When the multiple rubber pads 19 leave the wire core and reset, under the action of the spring three 35, each outlet tube 37 will automatically move outward and the hole groove 33 on each outlet tube 37 will be hidden in the corresponding sealing ring 34, thereby preventing the flux from being discharged along the outlet tube 37.

[0041] It should be noted that the flux can be selected to have a certain viscosity. The flux is a well-known prior art and will not be elaborated on. After the flux with a certain viscosity falls on the surface of the wire core after gathering and twisting, it can make the wire core become a more stable and less likely to loosen, avoiding the rebound of several bundles in the wire core, and the flux can further improve the welding firmness between the conductive sheet of the power socket 2 and the wire core of the power cable 8, thereby further improving the processing quality of the power supply.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
