[0037] Such as Figures 1 to 6As shown in the figure, an automatic wire clamping and soldering mechanism includes a machine base 1. In this embodiment, a power system for providing power and a control system for controlling the operation of various devices and equipment on the machine base 1 are provided at the bottom of the machine base 1. On one side of the top of the machine base 1, there is a mounting rack, and a control panel for adjusting the soldering temperature is provided on the mounting rack, which is convenient for the staff to control the soldering temperature. A turntable is provided on the top of the machine base 1, and an operating table for manually placing wires is provided at the front end. A soldering station 2 is rotatably connected to the turntable, and the height of the soldering station 2 is increased by the turntable, which is convenient for subsequent soldering work. In addition, several fixing devices 3, two wire clamping devices 4, two soldering devices 5, a feeder 8, a receiver 9, a pusher 6, and two detection components 7 are also provided on the machine base 1. Through the above devices and equipment, the automatic wire clamping and soldering mechanism can realize automatic wire clamping, automatic soldering, automatic feeding and receiving, and can automatically control the soldering temperature, time, and accurately locate the soldering point, improving the soldering quality and production efficiency at the same time.

[0038] Specifically, as Figure 1 shown in the figure, a plurality of equally spaced fixing devices 3 for fixing the soldering block and the wire are fixedly connected to the top edge of the soldering station 2 by welding. A wire clamping device 4 for clamping the wire to the soldering block and a soldering device 5 for soldering the wire to the outside of the soldering block are provided on the outer periphery of the soldering station 2. The soldering device 5 and the wire clamping device 4 are both fixedly connected to the top edge of the machine base 1 by screwing and are both facing the fixing device 3. The soldering device 5 is located on one side of the wire clamping device 4. The above devices are all electrically connected to the power system at the bottom of the machine base 1. Through the above settings, automatic wire clamping of the soldering block and the wire and the soldering process can be realized, improving the soldering quality.

[0039] As Figure 2 shown in the figure, a feeder 8 for conveying the soldering block and fixing the soldering block on the top of the fixing device 3 is provided on the outer periphery of the soldering station 2 and on the top surface of the machine base 1. The feeder 8 is located on the side of the wire clamping device 4 away from the soldering device 5 and is fixedly connected to the machine base 1. The feeder 8 includes a conveyor belt for conveying the soldering block, an adjustment wire fixed on one side of the conveyor belt for adjusting the placement method of the soldering block, and a mechanical gripper at one end of the conveyor belt for clamping and placing the soldering block from the conveyor belt onto the fixing device 3. The conveyor belt is spirally arranged on one side of the machine base 1, and the soldering block slides from the top of the conveyor belt to the bottom of the conveyor belt. The adjustment wire is located inside the conveyor belt. When the placement method of the soldering block is incorrect, it will be blocked by the adjustment wire during the process of being conveyed to the bottom of the conveyor belt until it is adjusted to the correct placement method. Through the above design, automatic alignment of the soldering block can be realized.

[0040] As Figure 2As shown in the figure, the mechanical gripper includes a support frame welded to the top surface of the machine base 1. A cylinder 431 is connected to the top of the support frame, and this cylinder 431 is electrically connected to the power system at the bottom of the machine base 1. A sliding rod is provided on one side of the cylinder 431, and an installation block is fixedly connected to the other side of the sliding rod by screwing. Sliding grooves are provided on both sides of the installation block, and sliding blocks are slidably connected to the outside of the installation block through the sliding grooves. Both ends of the bottom of the sliding block are movably connected with clamping blocks. When the welding block reaches the bottom of the mechanical gripper, the sliding blocks slide along the bottom of the installation block, and the clamping blocks move relatively to tighten and clamp the welding block. At this time, the piston in the cylinder 431 starts to move, pushing the sliding rod to move, and then pushing the installation block fixed on the sliding rod, so that it slides to the top of the fixing device 3. Subsequently, the sliding blocks slide towards the bottom of the installation block until the welding block is fixed on the fixing device 3; then the sliding blocks move along the top of the installation block, the piston in the cylinder 431 starts to move, pushing the sliding rod to move, and then pushing the installation block fixed on the sliding rod, so that it slides back to its original position. By repeating this process, the mechanical gripper can transport the welding block. Through the above settings, the functions of automatically aligning the feeder 8 and automatically fixing the welding block on the fixing device 3 are realized, improving the welding efficiency.

[0041] In this embodiment, a receiver 9 is also provided for collecting the welding blocks on the top of the fixing device 3. The receiver 9 is electrically connected to the power system at the bottom of the machine base 1. The receiver 9 is located on the side of the feeder 8 away from the wire clamping device 4 and is arranged outside the machine base 1, and a mechanical gripper is provided at one end close to the soldering station 2. In addition, a receiving box is equipped at the bottom of the receiver 9 for collecting the welded welding blocks, realizing automatic material collection and reducing labor costs.

[0042] As Figure 3 shown in the figure, a pusher 6 for pushing the wire is fixedly connected to the top surface of the soldering station 2. The pusher 6 is located at the middle position of the soldering station 2 and is directly opposite to the fixing device 3. The pusher 6 includes a cylinder 431 and a pushing rod on one side of the cylinder 431. A reinforcing block is fixed outside the cylinder 431, and a pushing block is fixedly connected by screwing on one side of the pushing rod. The pushing block is directly opposite to the fixing device 3 and is used to push the wire on the fixing device 3. The movement of the piston in the cylinder 431 is controlled by the control system in the machine base 1. When the air source supplies air, the piston of the cylinder 431 will push the pushing rod outwards, and the pushing rod moves forward to push the wire on the fixing device 3 to the position for wire clamping and soldering, facilitating its subsequent wire clamping and soldering operations.

[0043] As Figure 4 and Figure 6As shown in the figure, the wire clamping device 4 includes a robotic arm 41 for providing support force, a clamping member 42 movably connected to one end of the robotic arm 41. The robotic arm 41 is fixedly connected to the top of the machine base 1. A driving assembly 43 is provided inside the robotic arm 41, and the driving assembly 43 is used to drive the clamping action of the clamping member 42. The driving assembly 43 includes a cylinder 431 and a movable rod 432 movably connected to one side of the cylinder 431. The other side of the movable rod 432 is rotatably connected to the clamping member 42 through a rotating shaft. The cylinder 431 is fixed inside the robotic arm 41 by bolts and is electrically connected to the power system at the bottom of the machine base 1. The cylinder 431 is used to make the movable rod 432 move in a straight line, and the movable rod 432 pushes the clamping member 42 through the rotating shaft to clamp the wire outside the welding block. When the cylinder 431 works, the movable rod 432 will push outwards, and at the same time push the clamping member 42 to move outwards until the clamping member 42 hits the bottom of the fixing device 3. The reaction force of the impact acts through the rotating shaft to make the upper and lower clamping members 42 move relatively towards the middle and clamp, thereby clamping and fixing the wire on the welding block. Through the above design, the automatic wire clamping function of the wire clamping device 4 is realized.

[0044] As Figure 4 shown in the figure, the soldering device 5 includes a soldering gun 51 and a hot air blower 52 for providing hot air. The hot air blower 52 is arranged on one side of the soldering gun 51 close to the wire clamping device 4 for preheating in advance, improving the fluidity and wettability of the welding material, making the solder easier to spread on the welding surface and form a uniform weld seam, reducing defects such as pores and inclusions during welding, and improving the firmness and tightness of welding.

[0045] Specifically, as Figure 5 shown in the figure, the soldering gun 51 of this embodiment includes a support column and a welding gun head on the support column. A card slot is provided at the top of the support column, and the welding gun head is rotatably connected to the card slot through a rotating shaft. The rotation welding frequency of the welding gun head is controlled by the control system on the machine base 1. Through the above design, the automatic soldering function of the welding gun can be realized. When maintenance or replacement of the welding gun head is required, the maintenance cost and time can be reduced.

[0046] As Figure 1 shown in the figure, a detection component 7 is provided at the top of the soldering gun 51. The detection component 7 includes a camera 71 fixedly connected to the top of the machine base 1, an image display 72 for displaying the welding condition, and a lamp bead for providing light. The camera 71 is arranged at the top of the soldering gun 51, the lamp bead is arranged at the bottom of the camera 71 and fixed to the mounting bracket of the machine base 1, and the image display is arranged at the top of the camera 71. The camera 71 is used to photograph and record the welding process, and transmit the image information to the image display 72 for display, so that the staff can monitor the welding process in real time and make necessary adjustments.

[0047] As Figure 3As shown, the fixture 3 includes a fixing block 31 for securing the soldering block, and a fixing bracket 32 on one side of the fixing block 31 for securing the wires. The fixing block 31 is fixedly connected to the edge of the soldering station 2. A clamping block is welded to the top of the fixing block 31, and the soldering block is fixed to the clamping block by clamping. This arrangement facilitates the fixing and removal of the soldering block. Limiting rods are provided on both sides of the fixing bracket 32. The limiting rod near the outer side of the soldering station 2 is equipped with a clamping groove for clamping the wires. This arrangement facilitates the fixing and separation of the wires.

[0048] like Figure 1 As shown, a light shielding plate 81 is provided on the top of the welding station 2. The light shielding plate 81 is fixedly connected to one side of the feeder 8 and is arranged on the top of the operating table. It is located in the middle position of the feeder 8 and the wire clamping device 4. The light shielding plate 81 can reduce the influence of light and heat generated in the welding area and improve the safety of the work of the staff.

[0049] The automatic wire clamping and welding mechanism of this embodiment can clamp and weld two wires. When the welding block is transported by the conveyor belt to the bottom of the mechanical gripper, the gripper moves downward to grip the welding block, then lifts it up and makes a linear motion toward the welding table 2 until it reaches the top of the clamping block. The gripper then moves downward to clamp the welding block onto the clamping block, then returns and repeats the process. As the welding table 2 rotates, the welding block first rotates onto the operating table, where a worker places two wires onto the fixture 3. One end of the first wire is secured in a slot on the fixture 32, and the other end rests on the top of the welding block, near the fixture 32. One end of the second wire is placed on the top of the fixture 32, away from the slot, and the other end rests on the top of the welding block, away from the fixture 32. The welding block then rotates to the front of the first wire clamping device, which clamps the first wire to the welding block. The welding block then moves to the front of the first hot air cylinder for preheating, and the first welding device then welds the first wire. This completes the clamping and welding operations for the first wire.

[0050] After the first conductor is clamped and welded, the pusher 6 pushes the second conductor from the side of the fixing frame 32 into the clamping slot. The second clamping device then clamps the second conductor to the welding block. The welding block is then transferred to the front end of the second hot air cylinder for preheating. The second welding device then welds the second conductor, completing the clamping and welding operations. Finally, the receiver 9 stores the clamped and welded welding block into the receiving box.

[0051] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
