[0002] The pin welding tool is a device specially used for fixing and welding pins. In the traditional welding process, the fixing of pins has always been a problem, because the pins need to pass through the bottom of the top cover from bottom to top, and then the two are placed on the substrate. In this process, the pins are easy to fall off. Therefore, a positioning device is needed that can effectively support and position the pins and uniformly crimp them to the substrate.

In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0004] The fully automatic pin positioning device comprises a limit plate, a plurality of limit seats arranged on the top of the limit plate, an upper cover plate which is movable and positioned on the plurality of limit seats, and a bottom plate which is arranged below the limit plate and cooperates with the lifting guide thereof; a plurality of through pin holes are arranged in the limit seat, a supporting space for limiting a plurality of substrates is formed between the plurality of limit seats, a pin is arranged in the pin hole, one end of the pin is arranged against the substrate, and the other end of the pin is arranged against the bottom plate.

[0005] Specifically, each vertex angle position of the limit plate is connected to the bottom plate via a pin-type screw.

[0006] Specifically, a linear bearing is arranged outside the pin-type screw.

[0007] Specifically, a cover plate groove for positioning the upper cover plate is provided on the top of the limiting seat.

[0008] Specifically, each vertex corner of the upper cover plate is positioned in the cover plate groove.

[0009] Specifically, a substrate groove for positioning the substrate is provided on the top of the limiting seat.

[0010] Specifically, each vertex corner of the substrate is positioned in the substrate groove.

[0011] Specifically, the bottom surface of the substrate is in contact with a plurality of pins for welding.

[0012] Compared with the prior art, the beneficial effects of the fully automatic pin positioning device of the utility model are mainly reflected in:

[0013] By inserting the pins from top to bottom in the limiting plate, a number of pins are pressed against the bottom plate, and the bottom plate pushes the pins back to the substrate, so that the bottom surface of the substrate effectively contacts all the pins, avoiding the problem of poor contact of the pins, thereby improving the welding quality of the pins and the substrate.

[0019] The technical solutions in the embodiments of the present utility model are clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Example:

[0021] Reference Figure 1-3 As shown, this embodiment is a fully automatic pin positioning device, including a limit plate 1, a plurality of limit seats 2 arranged on the top of the limit plate 1, an upper cover plate 3 that is movably covered and positioned on the plurality of limit seats 2, and a bottom plate 4 that is arranged below the limit plate 1 and cooperates with the lifting guide thereof; a plurality of through pin holes 21 are arranged in the limit seat 2, and a supporting space for limiting a plurality of substrates 5 is formed between the plurality of limit seats 2, a pin 51 is arranged in the pin hole 21, one end of the pin 51 is arranged against the substrate 5, and the other end of the pin 51 is arranged against the bottom plate 4.

[0022] Each vertex position of the limiting plate 1 is connected to the bottom plate through a pin-shaped screw 11 , and a linear bearing 12 is arranged outside the pin-shaped screw 11 , so that the bottom plate 4 can be lifted, opened and closed stably relative to the limiting plate 1 .

[0023] A cover plate groove 22 for positioning the upper cover plate 3 is provided on the top of the limiting seat 2 , and each vertex position of the upper cover plate 3 is positioned in the cover plate groove 22 , so as to keep the upper cover plate 3 stably positioned on a plurality of limiting seats 2 .

[0024] A substrate groove 23 for positioning the substrate 5 is provided on the top of the limiting seat 2 . Each vertex position of the substrate 5 is positioned in the substrate groove 23 , ensuring that the substrate 5 is stably positioned in the plurality of substrate grooves 23 .

[0025] The length of the pins 51 is greater than the positioning height between the substrate 5 and the limiting plate 1. The pins 51 penetrate the limiting plate 1 and abut against the bottom plate 4. The bottom surface of the substrate 5 is in contact with the pins 51 for welding.

[0026] When this embodiment is applied, the limit plate 1 is in a positioning state, the bottom plate 4 is slidably connected relative to the limit plate 1, and the bottom plate 4 is in an extended state under the action of its own weight. A number of pins 51 penetrate into the pin holes 21, and a number of pins 51 abut against the surface of the bottom plate 4; the limit plate 1 is in a descending state, and the bottom of the bottom plate 4 contacts the platform surface (not shown in the figure), and the bottom plate 4 pushes the number of pins 51 upward, and a number of pins 51 abut against the bottom surface of the substrate 5, and the substrate 5 moves in the same direction until it abuts against the bottom surface of the upper cover plate 3 to limit the height; the contact position between the substrate 5 and the pins 51 is welded.

[0027] In the present embodiment, the pins 51 are inserted into the limiting plate 1 from top to bottom, and a number of the pins 51 are pressed against the bottom plate 4. The bottom plate 4 pushes the pins 51 back to the substrate 5, so that the bottom surface of the substrate 5 effectively contacts all the pins 51, thereby avoiding the problem of poor contact of the pins 51 and improving the welding quality of the pins 51 and the substrate 5.
