Description

Technical Field

[0001] The utility model relates to the technical field of rectifier bridge processing, in particular to a glue dispensing device for rectifier bridge production. Background Art

[0002] As we all know, the rectifier bridge generally carries a sufficiently large inductive load, so there is no current discontinuity in the rectifier bridge. When the rectifier bridge is generally used, a smoothing reactor is often connected to its load end, so its load can be regarded as a constant current source. Multiple groups of three-phase rectifier bridges are connected to each other so that the harmonics generated by the rectifier bridge circuit cancel each other out. According to the type of rectifier transformer, it can be divided into traditional multi-pulse transformer rectifier and auto-coupling multi-pulse transformer rectifier. The traditional multi-pulse transformer rectifier uses an isolation transformer to achieve isolation between the input voltage and the output voltage, but the rectifier transformer has a large equivalent capacity and a bulky volume.

[0003] The rectifier bridge needs a dispensing device during processing. The application number is CN202223165465.1. The patent name is a fast dispensing device for the production and processing of the rectifier bridge. A fast dispensing device for the production and processing of the rectifier bridge is disclosed, which belongs to the field of dispensing devices, including a dispensing machine body, a dispensing mechanism is arranged on the dispensing machine body, and a bearing table is movably installed on the table of the dispensing machine body. During the placement of the pallet, one side of the pallet fits the alignment arm on the side of the bearing table, and the other side of the pallet fits the alignment arm behind the bearing table, so that it is convenient for the pallet to be accurately placed at the center of the bearing table, ensuring that the placement of the pallet is unified each time, which can save the adjustment of the automatic dispensing program, thereby reducing the trouble of the dispensing machine dispensing error caused by the inaccurate position of the pallet. Through the anti-slip card plate and the elastic block, the clamping port between the anti-slip card plate and the alignment arm clamps the pallet, so that the position of the pallet on the bearing table can be fixed, thereby reducing the trouble of the bearing table shaking and shifting when the bearing table slides to adjust the position, and can also prevent the problem of displacement of the pallet caused by external force factors.

[0004] The above structure also has the disadvantages of unstable clamping and slow centering clamping response. When glue residue is left, it is inconvenient to clean up. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4, A dispensing device for the production of a rectifier bridge, comprising a workbench 1, a dispensing assembly and a support assembly. The dispensing assembly and the support assembly are arranged at one end of the workbench 1. The dispensing assembly includes a support frame 2, a first electric slide rail 3, a first electric slider 4, a lifter 5 and a dispenser 6. The support frame 2 is in a U shape, and the two free ends of the support frame 2 are arranged on the workbench 1. The first electric slide rail 3 is arranged on the top wall of the support frame 2 near the support assembly. The first electric slider 4 is slidably connected to the first electric slide rail 3. The first electric slider 4 protrudes from the first electric slide rail 3 and is provided with the lifter 5. The output end of the lifter 5 is provided with the dispenser 6. The support assembly includes a first sliding frame 7, a first left-right threaded screw 8, a first motor 9, a first slider 10, a second sliding frame 11, a second left-right threaded screw 12, a second motor 13, a second slider 14, a clamping block 15 and a moving assembly. A moving assembly for driving the first sliding frame 7 to move is arranged on the workbench 1. The first left-right threaded screw 8 and two groups of symmetrically arranged first sliders 10 are arranged in the first sliding frame 7. The first left-right threaded screw 8 is threadedly connected to the first slider 10. The output end of the first motor 9 penetrates through the side wall of the first sliding frame 7 and is connected to the first left-right threaded screw 8. The second sliding frame 11 is arranged on the first slider 10. The second left-right threaded screw 12 and two groups of symmetrically arranged second sliders 14 are arranged in the second sliding frame 11. The second left-right threaded screw 12 is threadedly connected to the second slider 14. The output end of the second motor 13 penetrates through the second sliding frame 11 and is connected to the second left-right threaded screw 12. The clamping block 15 is arranged on the second slider 14.

[0025] At first, start the first motor 9. The first motor 9 drives the first left-right threaded screw 8 to rotate, and the two groups of first sliders 10 move towards each other. Then start the second motor 13. The second motor 13 drives the second left-right threaded screw 12 to rotate, and the two groups of second sliders 14 move towards each other. The clamping block 15 stably clamps the material in a centered manner. Cooperating with the moving assembly, it is convenient to adjust the front and rear positions of the material. The first electric slide rail 3 drives the first electric slider 4 to move. Start the lifter 5. The lifter 5 drives the dispenser 6 to dispense glue on the material. In this embodiment, both the first motor 9 and the second motor 13 are servo motors, with rapid response and precise control.

[0026] During the actual use process, it is inevitable that glue will leak. If it accumulates in the first sliding frame 7, it is easy to affect the stable operation of the first slider 10. Therefore, cleaning holes are arranged on the front and rear sides of the first sliding frame 7.

[0027] In the above structure, if only the clamping block 15 is used to clamp and support the material, unstable clamping may occur. In order to solve the above problem, the width of the first slider 10 is greater than that of the second slider frame 11. The second slider frame 11 is arranged at an end away from the first slider frame 7. The second slider frame 11 is perpendicular to the first electric slide rail 3. The first slider 10 provides stable support, and the bottom wall of the clamping block 15 is higher than the first slider 10.

[0028] In this embodiment, the lifter 5 adopts a cylinder to ensure the operation stability of the lifter 5.

[0029] In order to facilitate the stable movement of materials forward and backward, the moving component includes a second electric slide rail 16 and a second electric slider 17. The second electric slide rail 16 is arranged perpendicular to the support frame 2. The second electric slider 17 and the second electric slide rail 16, the first slide frame 7 is set on the second electric slider 17, and the second electric slide rail 16 drives the second electric slider 17 to move, so as to facilitate the adjustment of the position of the material on the first slide frame 7.
