Technical Field

[0001] The utility model relates to the technical field of pin row processing, in particular to an auxiliary pin row device which is convenient for alignment. Background Art

[0002] Pin headers and female headers are common types of connectors in electronic components, used to connect circuit boards or between circuit boards and other external devices. Pin headers are usually a row of metal pins with an upright design, and the tips are used to insert into the holes of the circuit board, while female headers are usually used in conjunction with pin headers to form a board-to-board connection. When installing pin and female headers, you first need to fix the board, and then fix the pin headers to the circuit board. You can install them by welding, inserting or pressing them in. Next, align the female header with the pin header and make sure there is a "consistent click" at the bottom to confirm whether the connection is firm.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-5 The utility model provides an embodiment: an auxiliary needle arrangement device for aligning, comprising a base 1, a fixing plate 2 is arranged on one side of the upper end surface of the base 1, and the fixing plate 2 is welded and fixed to the base 1, and a telescopic mechanism 3 is installed on the inner side of the fixing plate 2; and further comprising:

[0028] The needle row positioning mechanism 6 is arranged at the middle position of the upper end surface of the base 1, and the bottom of the needle row positioning mechanism 6 is slidably limited with the base 1;

The pin row positioning mechanism 6 and the female row positioning mechanism 7 are both provided with a transmission cavity inside, and a gear 14 is installed at the center of the transmission cavity. The upper and lower ends of the gear 14 are both provided with movable rods 15, and the movable rod 15 is limited by sliding with the transmission cavity. A tooth groove 16 is provided on a side of the movable rod 15 close to the gear 14, and the tooth groove 16 is meshed with the gear 14;

[0030] The positioning plates 10 are respectively arranged at the front and rear of the inner sides of the pin row positioning mechanism 6 and the female row positioning mechanism 7 . The positioning plates 10 are slidably connected to the pin row positioning mechanism 6 and the female row positioning mechanism 7 through the guide groove 11 . One end of the movable rod 15 is fixed to the positioning plate 10 .

[0031] During positioning, the female and pin header assemblies are placed between the two positioning plates 10 respectively. At this time, the user rotates the rotary wheel 9 by hand to drive the worm 17 to rotate. The contact surface between the worm 17 and the worm wheel 18 forms a spiral friction transmission surface. The rotation of the worm 17 drives the worm wheel 18 to rotate, and then the worm wheel 18 drives the gear 14 to rotate. The upper and lower ends of the gear 14 are respectively meshed with the tooth grooves 16 on the movable rod. Under the meshing action of the two, the positioning plate 10 is driven by the movable rod 15 to move synchronously toward the direction of the female and pin header assemblies. During the movement, the female and pin header assemblies are guided to align with the center of the positioning mechanism, so that the female and pin header assemblies correspond to each other in the horizontal direction, so that the two can be accurately plugged in when they are plugged and fixed.

[0032] See also Figure 2 and Figure 3 A driving seat 8 is provided at the middle position of the outer side of the pin row positioning mechanism 6 and the female row positioning mechanism 7. A worm wheel 18 is rotatably installed inside the driving seat 8, and the shaft of the worm wheel 18 is fixed to the shaft of the gear 14. A worm 17 is installed on one side of the worm wheel 18, and the worm 17 is adapted to the worm wheel 18. By utilizing the self-locking property of the worm 17 and the worm wheel 18, the fixing effect of the positioning plate 10 on the female row and the pin row assembly can be improved, and the problem of reduced accuracy due to loosening can be avoided. Moreover, the positioning mechanism can adapt to a variety of female row and pin row assemblies, and the flexibility is effectively improved.

[0033] See also Figure 1 and Figure 4 A push rod 4 is installed inside the telescopic mechanism 3, and the push rod 4 and the telescopic mechanism 3 are slidably limited, and one end of the push rod 4 extends to the outside of the telescopic mechanism 3. A servo motor 19 is fixedly installed on one side inside the telescopic mechanism 3. A screw 20 is installed on the output shaft of the servo motor 19. The screw 20 extends to the inside of the push rod 4, and the screw 20 is threadedly connected with the push rod 4, which can drive the pin positioning mechanism 6 to move toward the female positioning mechanism 7.

[0034] See also Figure 2 A connecting seat 5 is installed at the other end of the push rod 4, and the connecting seat 5 is slidably connected to the push rod 4.

The output end of the pressure sensor 21 is connected to a microprocessor, and the output end of the microprocessor is connected to the servo motor 19, which effectively avoids the problem of incorrect insertion position due to path deviation.

[0035] See also Figure 1The front and rear ends of the needle row positioning mechanism 6 and the female row positioning mechanism 7 are both provided with guide seats 12, and the front and rear ends of the inner side of the fixed plate 2 are both fixedly installed with guide rods 13, and the guide rods 13 pass through the guide seats 12 on the needle row positioning mechanism 6 and are fixed with the guide seats 12 on the female row positioning mechanism 7. The guide seats 12 on the needle row positioning mechanism 6 are slidably connected with the guide rods 13 to improve the stability of the activity.

[0036] See also Figure 1 A rotary wheel 9 is rotatably mounted on the upper end of the driving seat 8, and the rotary wheel 9 is fixed to the upper end of the worm 17, which is convenient for the user to operate.

[0037] Furthermore, a rubber pad is adhered to the inner side of the positioning plate 10 .

[0038] Working principle: When in use, after the mother and pin assembly are positioned, the servo motor 19 is turned on, and its output shaft drives the screw 20 to rotate, causing friction in the inner screw hole of the push rod 4, and cooperating with the guiding effect of the inner cavity of the telescopic mechanism 3 on the push rod 4, the pin positioning mechanism 6 is driven to move toward the mother positioning mechanism 7 until the internal pin is plugged into the mother. If the pin is not aligned normally due to quality problems, the connecting seat 5 will squeeze the supporting spring, causing the detection end of the pressure sensor 21 to come into contact with the push rod 4, thereby timely reversing the servo motor 19 through the microprocessor to prevent further expansion of the damage to the two.
