Abstract
The utility model relates to a gravity PIN gland, including the welding jig, the last sleeve that is provided with of welding jig, be provided with gravity butt piece in the sleeve, gravity butt piece slides with the sleeve and is connected. In the welding process, if do not have the gland, then can lead to some components and parts to float high easily when the welding, but if whole gland, then because the tolerance of roughness and components and parts height, lead to pressing uneven, and gravity PIN sets up on the tool support plate according to the welding position of components and parts, gravity PIN includes sleeve and gravity butt piece, the utilization is come solitary every components and parts of pushing down with the gravity PIN who has appointed quality, avoid floating high, because it is that every components and parts push down alone, the influence of the high tolerance of the roughness of tool and components and parts just is completely excluded like this.
Description
Technical Field
The utility model relates to a gland, in particular to gravity PIN gland.
Background
The printed circuit board is also called PCB, flexible printed circuit board, etc. It has been widely used in the fields of communication, home appliances, etc. The chip and the IC integrated circuit are grains in the electronic information industry, and the semiconductor technology embodies the industrial modernization level of a country and guides the development of the electronic information industry. Electrical interconnection and assembly of semiconductors, integrated circuits, must be by circuit boards. Typically, various components are soldered to a printed circuit board by reflow soldering.
In the welding process, if no gland is arranged, part of components are easy to float high during welding, but the heights of the welded components are different by a plurality of overall glands, so that uneven pressing can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a gravity PIN gland.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a gravity PIN gland, includes the welding tool, be provided with the sleeve on the welding tool, be provided with gravity butt piece in the sleeve, gravity butt piece slides with the sleeve and is connected.
Preferably, one end of the gravity abutting piece, which is far away from the welding jig, is hemispherical.
Preferably, a sliding groove is formed in the sleeve, and the gravity abutting piece is connected in the sliding groove in a sliding mode.
Preferably, the gravity abutment is made of brass.
Preferably, the inner wall of the sliding groove is provided with a guide groove, and the gravity abutting piece is provided with a guide strip matched with the guide groove.
Preferably, the welding jig is provided with a mounting hole, and the sleeve is arranged in the mounting hole in a matched mode.
Preferably, the sleeve is provided with threads, and the sleeve is screwed in the mounting hole in a matching manner.
To sum up, the utility model discloses following beneficial effect has:
1. in the welding process, if do not have the gland, then can lead to some components and parts to float high easily when the welding, but if whole gland, then because the tolerance of roughness and components and parts height, lead to pressing uneven, and gravity PIN sets up on the tool support plate according to the welding position of components and parts, gravity PIN includes sleeve and gravity butt piece, the utilization is come solitary every components and parts of pushing down with the gravity PIN who has appointed quality, avoid floating high, because it is that every components and parts push down alone, the influence of the high tolerance of the roughness of tool and components and parts just is completely excluded like this.
Drawings
FIG. 1 is a schematic view of the overall structure of the embodiment;
fig. 2 is a sectional view of the entire structure in the embodiment.
In the figure, 1, a welding jig; 11. a sleeve; 12. a gravity abutting member; 111. a sliding groove; 112. a guide groove; 13. and (7) installing holes.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
Example (b):
a gravity PIN gland is shown in figures 1 and 2 and comprises a welding jig 1, wherein a sleeve 11 is arranged on the welding jig 1, a gravity abutting part 12 is arranged in the sleeve 11, and the gravity abutting part 12 is connected with the sleeve 11 in a sliding mode; in the welding process, if do not have the gland, then can lead to some components and parts to float high easily when the welding, but if whole gland, then because the tolerance of roughness and components and parts height, lead to pressing uneven, and gravity PIN sets up on the tool support plate according to the welding position of components and parts, gravity PIN includes sleeve 11 and gravity butt piece 12, utilize and come solitary every components and parts of pushing down with the gravity PIN who has appointed quality, avoid floating high, because every components and parts are pushed down alone, the influence of the high tolerance of the roughness of tool and components and parts just is completely excluded like this.
As shown in fig. 1, an end of the gravity abutting piece 12 facing away from the welding jig 1 is hemispherical.
As shown in fig. 1 and 2, a sliding groove 111 is provided in the sleeve 11, and the gravity abutment member 12 is slidably coupled in the sliding groove 111.
As shown in fig. 1, the gravity abutment 12 is made of brass.
As shown in fig. 1, the inner wall of the sliding slot 111 is provided with a guide slot 112, and the gravity abutting piece 12 is provided with a guide strip 121 engaged with the guide slot 112.
As shown in fig. 1 and 2, the welding jig 1 is provided with a mounting hole 13, and the sleeve 11 is fittingly disposed in the mounting hole 13.
As shown in fig. 1, the sleeve 11 is provided with a thread, and the sleeve 11 is screwed in the mounting hole 13.
The working principle is as follows:
in the welding process, if do not have the gland, then can lead to some components and parts to float high easily when the welding, but if whole gland, then because the tolerance of roughness and components and parts height, lead to pressing uneven, and gravity PIN sets up on the tool support plate according to the welding position of components and parts, gravity PIN includes sleeve 11 and gravity butt piece 12, utilize and come solitary every components and parts of pushing down with the gravity PIN who has appointed quality, avoid floating high, because every components and parts are pushed down alone, the influence of the high tolerance of the roughness of tool and components and parts just is completely excluded like this.
