Abstract
Description
Technical Field
[0001] This utility model belongs to the field of diode welding technology, and more specifically, it relates to a precision welding device for diode electrodes. Background Technology
[0002] To ensure welding precision, dual-pulse precision spot welding machines are mostly used when welding diode electrodes. During welding, the diode needs to be fixed on the welding table first, and then a multi-functional dual-pulse power supply with capacitor discharge is used. The spot welding machine has two independently adjustable pulse discharges in each welding process. One pulse is used to remove plating or contaminants, so as to improve the surface condition of the workpiece and achieve good contact between the electrode and the welding surface. The second pulse reliably welds the workpiece together, thereby ensuring the precision welding of the diode electrode.
[0003] For example, CN220612578U discloses a welding apparatus, which includes: a frame, a support fixture located on the frame, an upper electrode movably connected to the frame and located above the support fixture, a lower electrode movably connected to the frame and located below the support fixture, a grinding mechanism for grinding the welding portion of the upper electrode, and a transfer mechanism. The support fixture includes a welding area for placing a diode to be welded and a through hole located in the welding area and extending vertically. The lower electrode can pass through the through hole to contact the diode to be welded. The grinding mechanism is located on one side of the support fixture. The transfer mechanism can transfer the upper electrode between the welding area and the grinding mechanism. The above welding apparatus, through the grinding mechanism fixed on the frame, allows the upper electrode to be directly transferred to the grinding mechanism for grinding without disassembly when grinding is required, saving maintenance time for the upper electrode and increasing production output.
[0004] Based on the above, when welding diode electrodes, existing spot welding machines mostly use pressure plates to fix the diodes uniformly on the welding table. All the diode electrodes on the welding table need to be welded one by one before they can be removed and replaced with new ones. This results in a long downtime for the spot welding machine and affects the welding efficiency of the diode electrodes. Utility Model Content

This device solves the problem that in existing spot welding machines, diodes are mostly fixed to the welding table using pressure plates. All diode electrodes on the welding table need to be welded one by one before they can be removed and replaced with new ones.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model's anti-slip rubber pad increases the friction of the workpiece to be welded, preventing displacement during welding and effectively ensuring the fixation of the workpiece, thereby guaranteeing the welding effect on the diode electrodes. The movement of the position-fixing pressure plate automatically releases the diode's positioning, effectively avoiding the inconvenience of manually removing the pressure plate and reducing the workload of workers. Simultaneously, it allows for simultaneous welding and unloading, avoiding the need to weld all diode electrodes on the welding table one by one before removing them to replace with new workpieces, reducing downtime of the spot welding machine, improving its working efficiency, and thus increasing the welding efficiency of the diode electrodes. The action of the first and second limit push plates automatically pushes out the welded diode, facilitating its removal, reducing operational difficulty, and effectively improving the diode unloading efficiency.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0023] Example 1:
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] This utility model provides a precision welding device for diode electrodes, including a spot welding machine support 1, a limiting linear module 2, a sliding welding table 3, a position fixing pressure plate 4, a limiting structure, a limiting pressure inclined block 5, and a limiting extrusion plate 6; the limiting linear module 2 is bolted to the upper part of the spot welding machine support 1, and a slider is slidably connected to the upper part of the limiting linear module 2; the sliding welding table 3 is fixedly connected to the outside of the upper slider of the limiting linear module 2; multiple position fixing pressure plates 4 are provided, and multiple position fixing pressure plates 4 are evenly distributed and slidably connected to the upper part of the sliding welding table 3; the limiting structure is provided on the upper part of the sliding welding table 3; multiple limiting pressure inclined blocks 5 are provided, and multiple limiting pressure inclined blocks 5 are respectively fixedly connected to the upper part of multiple position fixing pressure plates 4; the limiting extrusion plate 6 is fixedly connected to the left side of the spot welding machine support 1.
[0026] The limiting structure includes a first limiting groove 302 and a second limiting groove 308; multiple first limiting grooves 302 are provided, and multiple first limiting grooves 302 are evenly distributed on the upper part of the sliding welding table 3; multiple second limiting grooves 308 are provided, and multiple second limiting grooves 308 are evenly distributed on the upper part of the sliding welding table 3.
[0027] The limiting structure also includes a limiting support strip 301 and an anti-slip rubber pad 403; the limiting support strip 301 is fixedly connected to the upper part of the sliding welding table 3; multiple anti-slip rubber pads 403 are provided, and multiple anti-slip rubber pads 403 are respectively bonded to the lower part of the fixed pressure plate 4 at multiple positions.
[0028] The limiting structure also includes a guide connecting cylinder 401 and a second reset elastic element 402; multiple guide connecting cylinders 401 are provided, and multiple guide connecting cylinders 401 are respectively fixedly connected to the left and right sides of multiple fixed pressure plates 4; multiple second reset elastic elements 402 are provided, and multiple guide connecting cylinders 401 are respectively elastically connected to the sliding welding table 3 through multiple second reset elastic elements 402.
[0029] The specific usage and function of this embodiment are as follows: When welding diode electrodes, the workpiece to be welded is first placed in the first limiting groove 302 and the second limiting groove 308, and the position to be welded is located above the limiting support bar 301. The sliding welding table 3 slides to the right along the limiting straight module 2 under the action of the slider. At this time, the limiting pressure inclined block 5 will gradually move away from the limiting extrusion plate 6. The second reset elastic element 402 will pull the position fixing pressure plate 4 to reset so that the anti-slip rubber pad 403 is in close contact with the workpiece to be welded and presses the workpiece to be welded. The guide connecting cylinder 401 will guide the movement of the position fixing pressure plate 4. When the sliding welding table 3 moves completely to the right side of the welding head, all the workpieces to be welded are pressed. At this time, the sliding welding table 3 moves to the left, and the welding head will weld multiple workpieces to be welded in sequence. The double pulse of the spot welding machine can improve the welding accuracy of the diode electrodes. During the process of the sliding welding table 3 moving to the left, the limiting pressure inclined block 5 will contact the limiting extrusion plate 6 in sequence, so that the position fixing pressure plate 4 above the welded diode is lifted.
[0030] Example 2:
[0031] As attached Figure 2 To be continued Figure 5 As shown:
[0032] Based on Embodiment 1, a pusher structure is also included; the pusher structure is disposed on the upper part of the sliding welding table 3.

[0035] The specific usage and function of this embodiment are as follows: When the position fixing plate 4 is lifted, the position limiting plate 305 is no longer blocked by the guide connecting cylinder 401. The first reset elastic member 306 pushes the sliding mounting plate 303 to reset, so that the first limiting push plate 304 and the second limiting push plate 307 push the soldered diode upward, making it convenient to remove the soldered diode. When the position fixing plate 4 is reset, the guide connecting cylinder 401 will squeeze the position limiting plate 305 again, so that the sliding mounting plate 303 drives the first limiting push plate 304 and the second limiting push plate 307 to retract.
