Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of auxiliary tooling, and in particular relates to a tooling for welding pins on a power board. Background Art
[0002] Pin header, a type of connector, is widely used in PCB board connection. It is known as a universal connector. Its function is to bridge the blocked circuit or isolated circuits, and is responsible for the task of current or signal transmission. It is usually used with female headers to form a board-to-board connection; or with electronic wiring harness terminals to form a board-to-wire connection; it can also be used independently for board-to-board connection.
[0003] Technicians in related fields have found that the current common manual welding method is to insert the pins of the pin header directly into the power board, and then use a solder gun to perform spot welding directly. However, because the power board and the pin header are not positioned, when the pin header is inserted into the power board for welding, the pin header will be tilted and not perpendicular to the power board. Although it generally does not affect the normal use effect, it will affect the overall appearance. Moreover, if the boards need to be connected through the pin header, the tilted welded pin header will cause the two boards to be misaligned. Forcing the boards to be straightened will affect the pins of the pin header. Utility Model Content
[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a tool for welding pin headers of a power board.

DETAILED DESCRIPTION
[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0023] like Figure 1 to Figure 4 As shown, a tooling for welding pins on a power board of the utility model comprises a metal plate 1, a column 2 is installed at a corner of the metal plate 1, a slide groove 3 is provided on the column 2, a lower clamping plate 4 is slidably installed on the slide groove 3, a screw rod 5 is rotatably installed on the column 2, the screw rod 5 is threadedly connected to the lower clamping plate 4, an upper clamping plate 6 is installed on the upper side of the lower clamping plate 4, the side of the upper clamping plate 6 contacts the side of the column 2, a bearing 7 is installed on the upper clamping plate 6, a screw rod 8 is fixedly installed on the inner ring of the bearing 7, and the screw rod 8 is threadedly connected to the lower clamping plate 4;
[0024] A rectangular column 9 is connected to the side of the column 2, a moving block 10 is sleeved and installed on the outer side of the rectangular column 9, and the moving block 10 is connected to a cylinder 11, and the cylinder 11 and the rectangular column 9 are perpendicular to each other;
[0025] The metal plate 1 is installed with a magnetic seat 12, and a connecting block 13 is installed on the top of the magnetic seat 12. The connecting block 13 is provided with a cross through hole 14, and the cross through hole 14 matches the specifications of the cylinder 11. A clamping seat 15 is connected to the top of the connecting block 13, and the clamping seat 15 is provided with a T-slot 16. Three sockets 17 are slidably placed in the T-slot 16, and the sockets 17 are provided with a jack 18. The clamping seat 15 is provided with a movable groove 19, and a top block 20 is slidably installed in the movable groove 19. The end of the top block 20 corresponds to the side of the T-slot 16. The clamping seat 15 is threadedly connected with a rotating rod 21, and the end of the rotating rod 21 contacts the side of the top block 20.
[0026] In this embodiment, when using a tooling for welding pins of a power board, the edge of the power board is placed on the lower clamping plate 4 so that it is parallel to the edge of the lower clamping plate 4, and then the screw rod 8 is rotated. Under the reaction force of the screw thread of the screw rod 8, the upper clamping plate 6 moves toward the direction of the lower clamping plate 4, thereby clamping the power board;
[0027] Insert the pin header into the socket 18 on the socket 17. Since the position of the socket 17 is not limited at this time, it can adapt to the placement of pin headers with different adjacent spacing sizes. After the pin header is placed, rotate the rotating rod 21 to move the top block 20 toward the T-slot 16 until the top block 20 contacts the side of the socket 17 and fixes the position of the socket 17, which is conducive to the rapid placement of subsequent pin headers of the same specification.
[0028] The screw rod 5 is rotated to make the lower clamping plate 4 rise and fall on the column 2, and the magnetic seat 12 on the metal plate 1 is manually and directly slid to align the pins of the pin header with the pin holes on the clamped power board. The rectangular column 9 and the circular column 11 are perpendicular to each other, which ensures that the direction of the placed pin header is horizontal, thereby ensuring the matching effect with the power board. After the position of the pin header is aligned, the magnetic seat 12 is started to determine the position of the pin header, and the screw rod 5 is rotated to make the lower clamping plate 4 descend. The pins of the pin header enter the pin holes of the power board, and manual or automatic welding can be started directly;
[0029] The arrangement of the cross through hole 14 allows the pin header to be placed in two directions, which is suitable for matching the horizontal or vertical welding of the pin header.
[0030] Preferably, the contact surfaces of the lower clamping plate 4 and the upper clamping plate 6 are fixedly mounted with rubber pads. With this design, the power board will not be injured when clamped. In fact, anti-injury measures can also be considered according to specific circumstances.
[0031] Preferably, a copper sleeve is installed at the contact position between the moving block 10 and the rectangular column 9. Such a design ensures smooth sliding while having good anti-wear effect and ensuring service life. In fact, protective measures can also be considered according to specific circumstances.
[0032] Preferably, the cross-section of the upper clamping plate 6 is L-shaped. This design expands the contact area between the upper clamping plate 6 and the column 2, thereby making it less likely for the upper clamping plate 6 to deviate in angle when subjected to the rotational force of the screw rod 8. In fact, the structure of the upper clamping plate 6 can also be considered based on specific circumstances.
[0033] Preferably, two guide pillars 22 are installed in the movable groove 19, and the top block 20 slides and matches with the guide pillars 22. Such a design ensures smooth movement of the top block 20. In fact, a structure that ensures smooth movement of the top block 20 can also be considered according to specific circumstances.
[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
