Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a tooling for quickly applying thermal conductive silicone grease to a rectifier bridge. Background Art

[0002] A rectifier bridge is an electronic device that converts alternating current with a level floating above and below zero into unidirectional direct current through the unidirectional conduction characteristics of a diode. Thermal conductive silicone grease needs to be applied to the rectifier bridge to fill the gap between the rectifier bridge and the heat sink so that the rectifier bridge can conduct energy normally, maintain the normal operating temperature of the rectifier bridge, avoid damage to the rectifier bridge, and extend its service life.

[0003] Currently, the thermal grease is applied to multiple rectifier bridges in turn by manually holding the rectifier bridges. The rectifier bridges need to be placed in the material box with the installation contact surface facing upwards, and the rectifier bridges are assembled directly from the material box.

[0004] When applying thermal grease on the rectifier bridge, the thickness of the applied thermal grease cannot be guaranteed, and the efficiency of single-piece application is low, resulting in wasteful repeated actions. Utility Model Content

[0005] The utility model aims to solve the problem of low smearing efficiency of rectifier bridge in the background technology and propose a tool for quickly smearing thermal conductive silicone grease of rectifier bridge.

[0006] The technical solution of the utility model is a tool for quickly applying thermal conductive silicone grease to a rectifier bridge, comprising:

[0007] A placement box, wherein two symmetrically arranged support plates are fixedly installed on the top of the placement box, a coating screen is fixedly installed inside the placement box, a rectifier bridge body is fixedly installed inside the placement box, and the coating screen is provided with a plurality of coating holes located directly above the rectifier bridge body;

[0008] The smearing assembly comprises a guide straight rod and a smearing plate, wherein the guide straight rods are fixedly installed on the opposite sides of the two support plates, and the smearing plate is slidably connected to the guide straight rods;

[0009] The smearing hole is provided with thermal conductive silicone grease, and the bottom of the smearing plate is in contact with the thermal conductive silicone grease.

[0010] Optionally, a plurality of the guide straight rods are provided, the plurality of the guide straight rods are parallel to the coating screen, a guide curved rod is fixedly installed between two adjacent guide straight rods, and the guide curved rod adopts an inverted U-shaped structure.

[0011] Optionally, there is a spacing between the multiple groups of application holes, the length of the guide curved rod is smaller than the spacing between two application holes in the left and right directions, and the guide curved rod is located directly above the spacing between the two application holes in the left and right directions.

[0012] Optionally, when the smear plate slides at the guide straight rod, the bottom of the smear plate contacts the smear hole; when the smear plate slides at the guide curved rod, the bottom of the smear plate is separated from the smear mesh plate.

[0013] Optionally, a nylon spiral column is rotatably connected inside the placement box, and the shaft of the nylon spiral column is threadedly connected to the coating mesh plate.

[0014] Optionally, a plurality of wedge-shaped guide blocks are fixedly mounted on both sides of the smear plate, the bottom of the wedge-shaped guide block is slidably connected to the smear mesh plate, and the wedge-shaped guide block is located between two smear holes in the front-to-back direction.

[0015] Optionally, a protective cover is snapped onto the outer wall of the placement box, and the protective cover is a transparent plastic cover.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] The utility model enables an smearing plate to slide on a guide straight rod, so as to scrape the thermal conductive silicone grease at the smearing hole into the hole of the smearing hole, thereby smearing the thermal conductive silicone grease on the rectifier bridge body. The rectifier bridge body is placed under multiple groups of smearing holes, so that multiple rectifier bridge bodies can be smeared at one time, the smearing efficiency is improved, and the actions consumed in taking and putting down the rectifier bridge body are saved, thereby saving the smearing efficiency.

[0018] Furthermore, the plurality of guide straight rods are parallel to the coating mesh plate, so that the distance between the bottom of the coating plate and the coating mesh plate is always stable, thereby making the thickness of the thermal grease coated on the rectifier bridge body stable.

[0019] Furthermore, when the smear plate moves to between the two groups of smear holes in the left and right directions, the smear plate moves to the guide bent rod and starts to move upward, avoiding smearing the thermal grease between the two groups of smear holes in the left and right directions, causing waste; the wedge-shaped guide block pushes the thermal grease between the two smear holes in the front and rear directions to the smear holes, avoiding waste.

[0033] like Figure 2 and 3 As shown, since there are multiple groups of coating holes 8, the rectifier bridge bodies 7 are placed under the multiple groups of coating holes 8, so that multiple rectifier bridge bodies 7 can be coated at one time, thereby improving the coating efficiency.

[0034] like Figure 2 , Figure 4 , Figure 5 As shown, a coating assembly 3 is provided between the two support plates 4, and the coating assembly 3 includes a guide straight rod 31 and a coating plate 33. The guide straight rod 31 is fixedly installed on the opposite side of the two support plates 4, and the coating plate 33 is slidably connected to the guide straight rod 31. Thermal grease is provided at the coating hole 8, and the bottom of the coating plate 33 is in contact with the thermal grease. The thermal grease at the coating hole 8 is scraped into the hole of the coating hole 8 by sliding the coating plate 33 on the guide straight rod 31, and since the rectifier bridge body 7 is located below the coating hole 8, the thermal grease will be coated on the rectifier bridge body 7.

[0035] A plurality of guide straight rods 31 are provided, and the plurality of guide straight rods 31 are parallel to the coating mesh plate 6 , so that the distance between the bottom of the coating plate 33 and the coating mesh plate 6 is always stable.

[0036] like Figure 2 As shown, the outer wall of the placement box 1 is clamped with a protective cover 2, and the protective cover 2 adopts a transparent plastic cover. The protective cover 2 plays a dustproof role to prevent dust from contacting with the thermal grease, resulting in poor thermal conductivity. The transparent cover allows the operator to see the internal coating status and stop coating in time when the coating is abnormal. The inside of the placement box 1 is rotatably connected with a nylon spiral column 5, and the rod of the nylon spiral column 5 is threadedly connected to the coating mesh plate 6.

Since the multiple guide straight rods 31 and the coating mesh plate 6 are parallel to each other, the thickness of the coated thermal grease is stable. The rectifier bridge body 7 is placed under the multiple groups of coating holes 8, so that multiple rectifier bridge bodies 7 can be coated at one time, which improves the coating efficiency and saves the actions of picking up and putting down the rectifier bridge body 7, thereby saving the coating efficiency.

The wedge-shaped guide block 34 pushes the thermal grease moved between the two smear holes 8 in the front-to-back direction to the smear holes 8 to avoid waste.

[0041] In this embodiment, when the smear plate 33 moves to between the two groups of smear holes 8 in the left and right directions, the smear plate 33 moves to the guide bent rod 32 and starts to move upward to avoid smearing the thermal grease between the two groups of smear holes 8 in the left and right directions, causing waste; the wedge-shaped guide block 34 pushes the thermal grease between the two smear holes 8 in the front and rear directions to the smear holes 8 to avoid waste.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
