Description

Technical Field

[0001] The utility model relates to the field of rectifiers, in particular to a processing mechanism for transformer rectifiers. Background Art

[0002] With the advancement of industrial production, the demand for high-current DC converters in various industries is increasing and becoming more stringent. The working principle of a rectifier is to convert AC into DC, which is achieved using rectifier diodes. For example, the mains electricity we use today is sinusoidal AC, which is rectified into DC using a bridge rectifier. Rectifiers require welding during production and processing.

[0003] Existing processing mechanisms for transformer rectifiers, such as patent number CN220739896U, discloses a welding device for processing transformer rectifiers. The device uses a telescopic cylinder to contract through four rectifier limit slots to drive the connecting block down, and then drives the connecting rod to push the clamping block to slide in the rectifier limit slot. The clamping block is used to clamp the rectifier in the rectifier limit slot, and the welding robot is used to weld the rectifier below it in conjunction with the rotation of the supporting plate. However, the four rectifiers are clamped and fixed uniformly, resulting in the supporting plate rotating to weld all four rectifiers before the rectifiers can be removed and replaced uniformly. It is inconvenient to disassemble and replace the rectifiers during the welding process, and it is inconvenient to limit and fix rectifiers of different sizes. In addition, the air compressor is used to blow air to cool the welded rectifier. The temperature of the gas blown out by the air compressor is relatively high, which is not conducive to rapid heat dissipation. Utility Model Content

[0022] The utility model is described in further detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a processing mechanism for a transformer rectifier, including a base 1, a turntable 2 and a welding robot 3. The turntable 2 is rotatably installed inside the base 1, and three placement turn blocks 4 are fixedly installed on the outside of the turntable 2. The three placement turn blocks 4 are equidistantly distributed in a ring shape on the outside of the turntable 2. A groove 5 is provided on the top of the base 1, the welding robot 3 is fixedly installed on the left rear of the top of the base 1, and a blowing assembly 6 is fixedly installed on the left side of the base 1.

[0024] The rectifier is fixed by setting a turntable 2 and cooperating with three placement turn blocks 4 installed on the side of the turntable 2. The rectifier is clamped from the side by setting a placement groove 42 in the placement turn block 4 and cooperating with the clamping plate 47 and the slide plate 411 located in the placement groove 42, so as to facilitate the fixation of rectifiers of different sizes and facilitate welding. The placement turn block 4 is rotated and switched between the welding robot 3 and the blowing assembly 6 to save the loading and unloading time in the rectifier processing and improve efficiency. At the same time, through the setting of the blowing assembly 6, the blowing assembly 6 can inhale external air, cool it down, and then blow it to the placement turn block 4, so as to cool the rectifier after welding, thereby improving the heat dissipation effect.

[0025] like Figure 3As shown, the placement rotating block 4 includes a connecting block 41, a placement groove 42 is provided inside the connecting block 41, a sliding groove 43 and a mounting groove 45 located on the inside and outside of the placement groove 42 are provided inside the placement groove 42, a limiting groove 44 connected to the sliding groove 43 is provided on the top of the connecting block 41, a sliding rod 46 is movably connected inside the sliding groove 43, a splint 47 is fixedly connected to the outside of the sliding rod 46, a handle 48 is fixedly connected to the top of the sliding rod 46, a two-way threaded rod 49 is rotatably installed inside the mounting groove 45, the outside of the two-way threaded rod 49 is fixedly connected to a handwheel 410 located outside the connecting block 41, and the external thread of the two-way threaded rod 49 is connected to a slide plate 411.

[0026] By placing the rectifier to be welded in the placement groove 42, and pulling the handle 48 outward, the handle 48 drives the slide rod 46 to slide outward along the sliding groove 43, and the handle 48 is located in the limit groove 44 for limiting, so that the clamping plate 47 on the outside of the slide rod 46 pushes the rectifier to clamp the rectifier in the clamping plate 47 and the placement groove 42, and the handwheel 410 is rotated to drive the bidirectional threaded rod 49 located in the installation groove 45 to rotate, and the rotation of the bidirectional threaded rod 49 drives the slide plates 411 symmetrically arranged on the left and right sides of the outside to slide inward to cooperate with the clamping plate 47 to limit and fix the rectifier, thereby facilitating the clamping and fixing of rectifiers of different sizes inside the placement groove 42, thereby ensuring a fixed welding effect.

[0027] like Figure 4 and Figure 5 As shown, the blowing assembly 6 includes a fixed frame 61, which is fixedly connected to the left side of the base 1. The top of the fixed frame 61 is fixedly connected to an air supply channel 62. A filter 63 is fixedly installed on the outside of the fixed frame 61. A blowing fan 64 is fixedly installed on the bottom of the air supply channel 62. A cooling plate 65 located on the outside of the blowing fan 64 is fixedly installed on the top of the air supply channel 62.

[0028] The rectifier that has just been welded is turned under the blowing fan 64. The blowing fan 64 draws air from the outside through the fixing frame 61 and passes through the filter 63 to block dust before entering the air supply channel 62. The air is guided to the surface of the cooling plate 65 through the air guide plate 66 in the air supply channel 62. The cooling plate 65 cools the bottom surface of the semiconductor cooling plate to cool the air and then flows out to the rectifier through the blowing fan 64 to cool it, thereby improving the cooling effect.

[0029] like Figure 4 As shown, the slide plate 411 is symmetrically arranged on the left and right sides of the bidirectional threaded rod 49 , and the lower part of the slide plate 411 is movably engaged in the installation groove 45 .

[0030] The slide plates 411 are symmetrically arranged on both sides of the bidirectional threaded rod 49 and are clamped in the mounting groove 45, so that the slide plates 411 can slide inward along the mounting groove 45 as the bidirectional threaded rod 49 rotates to clamp and fix the rectifier.

[0031] like Figure 3 As shown, a roller 412 located in the groove 5 is movably installed at the bottom of the connecting block 41 .

[0032] The roller 412 is located inside the groove 5 to ensure smooth rotation of the connecting block 41 .

[0033] like Figure 2 As shown, a servo motor is fixedly installed inside the base 1, and the servo motor and the turntable 2 are driven by mutually meshing gears.

[0034] The servo motor in the base 1 cooperates with the gear transmission on its output shaft and the outside of the turntable 2 to drive the turntable 2 to drive the placement of the turn block 4 to rotate at a fixed angle to facilitate the placement of the turn block 4 and switch between the welding robot 3 and the blowing assembly 6.

[0035] like Figure 2 As shown, the blowing fan 64 is located above the rotating block 4 .

[0036] By arranging the blowing fan 64 above the placement rotating block 4, the blowing fan 64 blows air from above the placement rotating block 4 toward the rectifier to cool it down.

[0037] like Figure 5 As shown, an air guide plate 66 facing the refrigeration plate 65 is fixedly connected to the interior of the air supply channel 62 .

[0038] The air entering is guided to the cooling plate 65 by the air guide plate 66 . The cooling plate 65 is a semiconductor cooling plate, and one surface of the cooling plate located inside the air supply channel 62 cools the air in contact with the cooling plate 65 .

[0039] The following is a detailed description of the working principle of the processing mechanism for the transformer rectifier.

[0040] like Figures 1 to 5As shown, the rectifier to be welded is placed in the placement groove 42, and the handle 48 is pulled outward to drive the slide bar 46 to slide outward along the slide groove 43. The handle 48 is located in the limiting groove 44 to limit the position so that the clamping plate 47 on the outside of the slide bar 46 pushes the rectifier to clamp the rectifier in the clamping plate 47 and the placement groove 42, and the hand wheel 410 is rotated to drive the bidirectional threaded rod 49 located in the installation groove 45 to rotate. The rotation of the bidirectional threaded rod 49 drives the slide plates 411 symmetrically arranged on the left and right sides of the outside to slide inward to cooperate with the clamping plate 47 to limit and fix the rectifier. The servo motor in the base 1 rotates the gears on its output shaft that mesh with the turntable 2, driving the turntable 2 to rotate, so that the rectifier in the placement groove 42 rotates. To the bottom of the welding robot 3, it is welded by the welding robot 3, and the three placement turn blocks 4 and the welding robot 3 and the blowing assembly 6 are all set at 120 degrees. After the welding robot 3 welds the current rectifier, the placement turn block 4 is driven by the turntable 2 to rotate so that the next rectifier is moved to the bottom of the welding robot 3, and the rectifier that has just been welded is rotated to the bottom of the blowing fan 64. The blowing fan 64 inhales air from the outside through the fixed frame 61 and passes through the filter 63 to block dust and then enter the air supply channel 62. It is guided to the surface of the cooling plate 65 through the air guide plate 66 in the air supply channel 62. The cooling plate 65 is used to cool the bottom surface of the semiconductor cooling plate to cool the air. After cooling the air, it is blown to the rectifier through the blowing fan 64 to cool it down and then rotated out for disassembly and replacement.

[0041] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
