Description

Soldering paste smearing frame

Technical Field

The utility model relates to the technical field of electronic component manufacturing, in particular to a soldering paste smearing frame.

Background

The rectifier bridge is used as a power component and is widely applied to various power supply devices to convert input alternating-current voltage into output direct-current voltage. Usually, a connecting piece is packaged in the rectifier bridge and connected with the pin. Before the connecting piece of the rectifier bridge is welded with the pin, solder paste needs to be coated on the connecting piece. The traditional manual smearing mode is that a screen plate is placed above a plate body provided with a connecting piece, and the screen plate is taken down after soldering paste is brushed on, so that the soldering paste can be attached to the connecting piece. However, this method is inefficient in applying solder paste, uniformity of application is difficult to ensure, and the screen plate needs to be additionally and separately placed. Therefore, a solder paste application stand is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a solder paste smearing frame, which solves the problems that the traditional solder paste smearing mode is low in efficiency and the smearing uniformity is difficult to guarantee.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

a soldering paste smearing frame comprises a base, wherein two supporting rods are fixedly arranged at the position, close to the edge, of the base, a fixed seat is arranged on each supporting rod, and a shaft rod penetrates through the two fixed seats and is movably connected with the fixed seats; a connecting rod is fixedly arranged on the shaft lever, and a balancing weight is arranged at one end of the connecting rod; the shaft lever on still fixed be provided with the connecting block, the connecting block keep away from the one end of balancing weight and be provided with the otter board.

Furthermore, a base plate is fixedly arranged above the base, and a limiting groove is formed in the upper end face of the base plate.

Furthermore, the base on be fixed with the nut, the bracing piece be the threaded rod, the bracing piece lower extreme fixed set up in the nut.

Furthermore, a bearing is fixedly arranged in the fixed seat, and the connecting rod is movably connected with the fixed seat through the bearing.

Furthermore, a fixing plate 10 with a C-shaped structure is fixedly arranged at one end, far away from the balancing weight, of the connecting block, and the net plate is fixedly arranged in the fixing plate.

Furthermore, the upper end face of the screen plate is also provided with a smearing groove.

The utility model has the beneficial effects that: by using the soldering paste smearing frame, the situation that soldering paste is not smeared in place can be avoided, the screen plate can be automatically lifted after the soldering paste is smeared, and the additional independent placement is not needed, so that the product quality is improved, and the production efficiency is also improved.

The utility model will be explained in more detail below with reference to the drawings and examples.

Drawings

Fig. 1 is a structural view of a solder paste applying frame according to the present invention.

Detailed Description

As shown in fig. 1, the solder paste smearing frame comprises a base 1, wherein two support rods 4 are fixedly arranged at the positions, close to the edge, of the base 1, a fixed seat 5 is arranged on each support rod 4, and a shaft lever 6 penetrates through the two fixed seats 5 and is movably connected with the fixed seats 5; a connecting rod 7 is fixedly arranged on the shaft lever 6, the connecting rod 7 can be fixed in the middle of the shaft lever 6, and a balancing weight 8 is arranged at one end of the connecting rod 7; the shaft lever 6 is further fixedly provided with a connecting block 9, and one end, far away from the balancing weight 8, of the connecting block 9 is provided with a screen plate 11.

Further, in order to facilitate better fit of the mesh plate 11 with the connecting sheet disc when the mesh plate is downward, a backing plate 2 is fixedly arranged above the base 1; in order to better limit the connecting sheet disc and prevent the disc body from moving to cause that the soldering paste is not coated in place, the upper end surface of the backing plate 2 is provided with a limit groove 21.

Further, in order to facilitate the installation of the supporting rod 4, the base 1 is fixedly provided with a nut 3, the supporting rod 4 is a threaded rod, and the lower end of the supporting rod 4 is fixedly arranged in the nut 3. The fixing seat 5 can be connected with the supporting rod 4 through a threaded structure, and the mounting height of the fixing seat 5 can be conveniently adjusted.

Further, in order to be movably connected better, a bearing is fixedly arranged in the fixed seat 5, and the connecting rod 7 is movably connected with the fixed seat 5 through the bearing.

Further, in order to fix the mesh plate 11 better, one end of the connecting block 9, which is far away from the counterweight block 8, may be welded and fixed with a fixing plate 10 having a C-shaped structure, and the mesh plate 11 is fixed in the fixing plate 10.

Furthermore, in order to facilitate the application of the solder paste and prevent the solder paste from being adhered to the outside, the upper end surface of the screen plate 11 is further provided with an application groove 111, and the mesh is arranged in the application groove 111.

The use method of the utility model comprises the following steps: the connecting sheet disc fully distributed with the connecting sheets is placed in the limiting groove 21, the screen plate 11 is pressed downwards, the screen plate 11 is attached to the connecting sheet disc, the mesh is just corresponding to the position of the connecting sheets, then soldering paste is placed in the smearing groove 111, the soldering paste is scraped into the mesh through the scraper, and the soldering paste can be stuck on the connecting sheets. After the painting is finished, the screen plate 11 is loosened, the screen plate 11 can be automatically lifted under the influence of the gravity of the balancing weight 8, and finally the connecting sheet disc is taken down.

The utility model has been described above with reference to the accompanying drawings, and it is to be understood that the utility model is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description, since various modifications may be made without departing from the spirit or scope of the utility model.
